[Maria-discuss] New Question: Migrating from MySQL 5.1.31-community >> MariaDB 5.5
by AskMonty KB 03 Oct '13

03 Oct '13

Hello, A new question has been asked in "Upgrading MariaDB" by flumpydog: -------------------------------- One of our internal development db servers is currently running MySQL 5.1.31-community on CentOS 5.9 as it suits are needs internally for testing only purposes of our sites. I would like to use this box to install and test MariaDB 5.5 on. What would be the best method to make this transition as smooth as possible? The MySQL rpm's are not the ones supplied by CentOS, but are from the MySQL site. Should I do a dump of all the databases on MySQL, remove all the MySQL rpm packages, install MariaDB 5.5 via yum and then do an import of the databases? Or will I have to install a prior release of MariaDB and upgrade from there? Also, all the tables are currently using the MyISAM storage engine. Just so I will have the best experience here and while I am experimenting, what storage engine would you recommend we try, Ari or? Some of these tables contain in excess of a million rows. Is there anything I should be aware of before converting tables? Thanks, Chuck -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/migrating-from-mysql-5131-community-mariadb-55/

[Maria-discuss] The MariaDB Foundation and MariaDB trademark?
by Jeremy Cole 02 Oct '13

02 Oct '13

While poking around on the various sites (discussed at length in previous threads) I was left wondering about the MariaDB trademark. I was under the impression this was going to be owned by and managed by the MariaDB Foundation. It seems like it was registered by Monty Program Ab though, and never transferred to or owned by MariaDB Foundation. So, after the acquisition it is now owned by SkySQL. The SkySQL site's "Trademarks" page<http://www.skysql.com/about/legal/trademarks>definitively confirms this with the text «The "MariaDB" trademark is wholly owned by SkySQL Corporation Ab and is a registered trademark in ...». So, I am left wondering what happened? Was my original understanding incorrect, or was this never properly followed through? While I would hope SkySQL is a good community member and would not do anything bad with the trademark, this does defeat a lot of the original idea with the foundation, by my understanding, and leaves a single commercial entity in more or less full control of MariaDB's future. Can anyone provide some insight? Regards, Jeremy

[Maria-discuss] New Question: yum Install on x86_64 CentOS 5.x
by AskMonty KB 02 Oct '13

02 Oct '13

Hello, A new question has been asked in "MariaDB community" by flumpydog: -------------------------------- I am attempting to install MariaDB on a x86_64 server running CentOS 5.9. I followed the instructions for "Installing MariaDB with yum", created the MariaDB.repo file, however when I run yum, it wants to install i386 rpm files and not x86_64. I even attempted to modify the MariaDB.repo file and use baseurl = http://yum.mariadb.org/5.5/centos5-amd64 , however this did not work. What can I do to correct this as I would like to do this all with yum. Thanks, Chuck -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/yum-install-on-x86_64-centos-5x/

Re: [Maria-discuss] [Maria-developers] [All] MariaDB's best (download) month ever
by Jean Weisbuch 30 Sep '13

30 Sep '13

(this thread was originaly from maria-developpers) The mariadb.com/.org distinction is not really clear as both have a similar layout, designs and duplicate contents, plus distincting both sites from the sole TLD is not the most visible one ; i must admit that the first time i ended up on mariadb.com i thought at first that it was just the mariadb.org website that had a design update. Plus, there is a link to "mariadb.org" on the top menu of mariadb.com, a link to "Community" or "MariaDB Foundation" or a clear title would be better.

[Maria-discuss] MySQL bug affects mariaDB
by Peter Laursen 27 Sep '13

27 Sep '13

I think the 'mysql' client with MariaDB has a similar problem as it has with MySQL - refer? http://bugs.mysql.com/bug.php?id=70443 MariaDB installer installs my.ini to /datadir - what with MariaDB is a subfolder to /basedir. The server will look for it correctly as the registry key defining the service has a --default-file specification. But the command line clients don't read the registry key. @Wlad? -- Peter -- Webyog

[Maria-discuss] multi master and conflicts
by Roberto Spadim 26 Sep '13

26 Sep '13

Hi guys, New problems to solve here =) if anyone could help should be nice :) I have an old system that use only one server with aria/myisam tables (some temporary tables and some views too) I want to implement a multi master replication (near to a cluster...), but i should take care about replication conflicts.... There's some good pratices or books about implementing multi master without replication conflicts? Should I change it to galera cluster? Well maybe.. I don't know what to do with aria storage, galera works with innodb/xtradb/myisam, what about aria? i didn't tested yet I don't know what to do about commit phase with myisam too, since galera do the certificate at commits phase before commit, and myisam problably do a autocommit at each insert/update/delete, this will be a problem, or not? The idea is not use innodb or I should implement some tables or views to have a faster COUNT/MIN/MAX functions (myisam is optimized for it), and i should rewrite some codes to use BEGIN, COMMIT, and cancel if connection is lost Well physical problems... Servers will not be online all time, the network link isn't good, servers are ~50km far via a wifi link with some tree and birds and others problems (that's why i think async replication is ok, instead of galera 'sync' cluster) Any idea is well come, but should be nice something that myisam/aria could be used I asked some days ago about replication and galera and xtradb cluster, but i'm not sure what to do yet tks guys! ideas are wellcome -- Roberto Spadim

[Maria-discuss] New Question: Migrating from MySql: MariaDB server closing client connections unexpectedly
by AskMonty KB 16 Sep '13

16 Sep '13

Hello, A new question has been asked in "General FAQ" by vivek_kubaji: -------------------------------- We in the process of migrating from MySql to MariaDB due to licensing/commercial usage reasons. We have successfully replaced the MySql connector jar with MariaDB client jar (first change) and are now trying to replace MySql server with MariaDB server without changing the data files. All our applications run perfectly for about 8-12 hours after which we see the following exception: org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.JDBCConnectionException: Cannot open connection Caused by: org.hibernate.exception.JDBCConnectionException: Cannot open connection at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:74) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:29) at org.hibernate.jdbc.ConnectionManager.openConnection(ConnectionManager.java:426) at org.hibernate.jdbc.ConnectionManager.getConnection(ConnectionManager.java:144) at org.hibernate.jdbc.JDBCContext.connection(JDBCContext.java:119) at org.hibernate.transaction.JDBCTransaction.begin(JDBCTransaction.java:57) at org.hibernate.impl.SessionImpl.beginTransaction(SessionImpl.java:1326) at org.springframework.orm.hibernate3.HibernateTransactionManager.doBegin(HibernateTransactionManager.java:494) at org.springframework.transaction.support.AbstractPlatformTransactionManager.getTransaction(AbstractPlatformTransactionManager.java:315) at org.springframework.transaction.interceptor.TransactionAspectSupport.createTransactionIfNecessary(TransactionAspectSupport.java:257) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:102) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:185) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:209) at $Proxy4.getMessageCountByStatus(Unknown Source) at com.onmobile.cmfweb.monitoring.CmfMessagesMonitor.getMessageCounts(CmfMessagesMonitor.java:56) at sun.reflect.GeneratedMethodAccessor625.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.springframework.util.MethodInvoker.invoke(MethodInvoker.java:270) at com.onmobile.cmfshare.MethodInvockingBean.invoke(MethodInvockingBean.java:28) at org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean$MethodInvokingJob.executeInternal(MethodInvokingJobDetailFactoryBean.java:212) at org.springframework.scheduling.quartz.QuartzJobBean.execute(QuartzJobBean.java:79) at org.quartz.core.JobRunShell.run(JobRunShell.java:203) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:520) Caused by: java.sql.SQLNonTransientConnectionException: Could not connect to localhost:3306: unexpected end of stream, read 0bytes from 4 at org.mariadb.jdbc.internal.SQLExceptionMapper.get(SQLExceptionMapper.java:136) at org.mariadb.jdbc.internal.SQLExceptionMapper.throwException(SQLExceptionMapper.java:106) at org.mariadb.jdbc.Driver.connect(Driver.java:114) at org.apache.commons.dbcp.DriverConnectionFactory.createConnection(DriverConnectionFactory.java:37) at org.apache.commons.dbcp.PoolableConnectionFactory.makeObject(PoolableConnectionFactory.java:290) at org.apache.commons.pool.impl.GenericObjectPool.borrowObject(GenericObjectPool.java:840) at org.apache.commons.dbcp.PoolingDataSource.getConnection(PoolingDataSource.java:95) at org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:544) at org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider.getConnection(LocalDataSourceConnectionProvider.java:81) at org.hibernate.jdbc.ConnectionManager.openConnection(ConnectionManager.java:423) ... 21 more Caused by: org.mariadb.jdbc.internal.common.QueryException: Could not connect to localhost:3306: unexpected end of stream, read 0bytes from 4 at org.mariadb.jdbc.internal.mysql.MySQLProtocol.connect(MySQLProtocol.java:509) at org.mariadb.jdbc.internal.mysql.MySQLProtocol.connect(MySQLProtocol.java:669) at org.mariadb.jdbc.internal.mysql.MySQLProtocol.<init>(MySQLProtocol.java:264) at org.mariadb.jdbc.Driver.connect(Driver.java:110) ... 28 more Caused by: java.io.EOFException: unexpected end of stream, read 0bytes from 4 at org.mariadb.jdbc.internal.common.packet.buffer.ReadUtil.readFully(ReadUtil.java:84) at org.mariadb.jdbc.internal.common.packet.buffer.ReadUtil.readFully(ReadUtil.java:92) at org.mariadb.jdbc.internal.common.packet.RawPacket.nextPacket(RawPacket.java:77) at org.mariadb.jdbc.internal.common.packet.SyncPacketFetcher.getRawPacket(SyncPacketFetcher.java:67) at org.mariadb.jdbc.internal.mysql.MySQLProtocol.connect(MySQLProtocol.java:467) ... 31 more The exceptions disappear if MySql server is used again. >From what I have debugged so far MariaDB server is closing the client connections for some reason. I initially suspected of idle connections but we are using Hibernate configurations like 'testOnBorrow' so it shouldn't be the case. Can anyone help us to find out the cause for this and help us fix the problem? Is there any specific configuration in MariaDB that I should be doing? I've even run our applications by increasing the value of the param 'interactive_timeout' in the MariaDB server but it did not help. Btw, we are using Spring-Hibernate and pooling our connections using Commons-pool jar. Any kind of help will be deeply appreciated.

[Maria-discuss] New Question: How to install MariaDB rpms in CentOS 6.4 using rpm (not yum cmd) + handling mysql-libs conflicts
by AskMonty KB 14 Sep '13

14 Sep '13

Hello, A new question has been asked in "MariaDB community" by theone: -------------------------------- I need to script the install of MariaDB using the rpm command in CentOS 6.4. I can't use yum since it's gong to be an offline install so there's no live access to the repository. The only MySQL package installed is mysql-libs as various other packages depend on it. When I did a test install of MariaDB with yum using the command: yum install MariaDB-client MariaDB-common MariaDB-compat MariaDB-devel MariaDB-server MariaDB-shared It correctly accounted for mysql-libs and uninstalled it at the end as MariaDB could handle the dependencies after it was installed: Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package MariaDB-client.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-common.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-compat.x86_64 0:5.5.32-1 will be obsoleting ---> Package MariaDB-devel.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-server.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-shared.x86_64 0:5.5.32-1 will be obsoleting ---> Package mysql-libs.x86_64 0:5.1.66-2.el6_3 will be obsoleted --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================================================================================== Package Arch Version Repository Size ==================================================================================================================================================================== Installing: MariaDB-client x86_64 5.5.32-1 mariadb 10 M MariaDB-common x86_64 5.5.32-1 mariadb 23 k MariaDB-compat x86_64 5.5.32-1 mariadb 2.7 M replacing mysql-libs.x86_64 5.1.66-2.el6_3 MariaDB-devel x86_64 5.5.32-1 mariadb 5.6 M MariaDB-server x86_64 5.5.32-1 mariadb 34 M MariaDB-shared x86_64 5.5.32-1 mariadb 1.1 M replacing mysql-libs.x86_64 5.1.66-2.el6_3 Transaction Summary My question is, what is the equivalent way to install the MariaDB packages using the rpm command only as opposed to yum? If I do rpm -ivh MariaDB*.rpm, I will get a ton of messages like the following about conflicts with mysql-libs: file /etc/my.cnf from install of MariaDB-common-5.5.32-1.x86_64 conflicts with file from package mysql-libs-5.1.66-2.el6_3.x86_64 file /usr/share/mysql/charsets/Index.xml from install of MariaDB-common-5.5.32-1.x86_64 conflicts with file from package mysql-libs-5.1.66-2.el6_3.x86_64 I used the --force option to install and then uninstalled mysql-libs and didn't get any weird messages but I'm not sure that is the cleanest method to handle the conflicts. So can someone confirm that installing MariaDB with the following rpm commands would be the same as using yum to install the packages and handle mysql-libs conflicts/removal: rpm -ivh --force MariaDB*.rpm rpm -e mysql-libs Thanks for any input! -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/how-to-install-mariadb-rpms-in-centos-64-using-rpm…

[Maria-discuss] New Question: Replication stops after one hour or so
by AskMonty KB 11 Sep '13

11 Sep '13

Hello, A new question has been asked in "Replication" by Martin22: -------------------------------- Hi there, we operate a big MariaDB-server (24 CPUs, 48 GB RAM, Version 5.5.32 with Percona XTRADB). Because it is mission-critical it is replicated to another server of similar size (row based replication). We get the ball rolling with "innobackupex" (GREAT tool to clone a life server). After setting the slave to its coordinates it starts up, catches up to the master (times behind = 0) and all is well. For an hour. Or four. Or two days. Then the slave suddenly stops executing the masters binlog. There are no errors logged. I checked the binlog and relaylog on master and slave around the last log entry processed and can't find anything strange. I'm at a total loss. I can't say that I'm an MySQL or MariaDB specialist, so I'd like to reach out to this community in order to get some idea what's happening. Anybody got an idea? Thanks in advance!

Many people have expressed to me and others working on MariaDB that it would make the most sense for the KB to be located under a MariaDB domain, so I'm happy to report that the KB is now at https://mariadb.com/kb If you've used the KB in the last couple of days, you've probably already noticed this as the change went live over the weekend. We've also updated the colors to match the new look of mariadb.com. We're working on a complete visual refresh to integrate it completely into the look and feel of the new site. But that will come later. For now it's the same KB with slightly different colors under a new domain. All https://kb.askmonty.org/... links should redirect automatically to the correct spot on the new site.

Hello, A new question has been asked in "Development" by mamfelt: -------------------------------- Since the current owner of mysql is no longer interested in creating/distributing for and IBM platforms - and, as a joomla user I am accustomed to using mysql as backend I am hoping to package and use mariadb on AIX. So, anyone else who has any (successful) experience with compiling mariadb for/on AIX? If yes, what OS level did you use, and compiler? I am trying with OS 5.3TL7 and AIX 6.1TL7. I will prefer to have it work on AIX 5.3 as that should support AIX 6.1 - but at this point I am just looking for a better starting point.

[Maria-discuss] New Question: Hibernate Reverse Engineering wizard with MariaDB
by AskMonty KB 22 Aug '13

22 Aug '13

Hello, A new question has been asked in "MariaDB Documentation" by JohnD: -------------------------------- (Sorry, couldn't find a good place for this query - perhaps there ought to be a folder "MariaDB and ORMs"?) I'm trying to use the Hibernate Reverse Engineering wizard with MariaDB. It's just a very simple example, but I am stuck. I don't see any errors, but it doesn't work as described. Here's what I've got so far: * Windows 7 x64, Eclipse Juno, MariaDB v5.5.3, Hibernate v4.2.3 * I've got an example with Hibernate running using annotations and the same instance of MariaDB, no problem * Now I want to create the classes from the tables, so I'm trying to use the reverse engineering wizard. * I've set up a simple DB and a couple of tables * I've set up a hibernate.cfg.xml file using the same values as my working annotation example * Now I use the wizard (in Eclipse) to "New/Hibernate Reverse Engineering File (reveng.xml)" ** First page ok, second page "Configure Table filters" is where I'm stuck ** I select the correct Console configuration (generated as part of creating the config file) and then press the "Refresh" button ** At this point I should see my two tables in the "Database schema:" column. But it's empty. ** I briefly see "Pending..." - then nothing. ** I can't see any errors. So, how to move forwards? Can I turn on some logging? Where is the error? What logs to check? The Eclipse console window shows a bunch of stuff, all info, no errors and the last three lines are like this: * 2013-08-22 11:34:38,189 DEBUG Worker-33 org.hibernate.connection.DriverManagerConnectionProvider - opening new JDBC connection * 2013-08-22 11:34:38,198 DEBUG Worker-33 org.hibernate.connection.DriverManagerConnectionProvider - created connection to: jdbc:mysql://localhost:3306/omthibernate, Isolation Level: 4 * 2013-08-22 11:34:38,199 INFO Worker-33 org.hibernate.connection.DriverManagerConnectionProvider - cleaning up connection pool: jdbc:mysql://localhost:3306/omthibernate In case it helps, here is the hibernate config (I've tried a lot of variations): {{{ <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="xxx"> <property name="hibernate.connection.driver_class">org.mariadb.jdbc.Driver</property> <property name="hibernate.connection.password">password</property> <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/omthibernate</property> <property name="hibernate.connection.username">user</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> </session-factory> </hibernate-configuration> }}} -------------------------------- To view or answer this question please visit: http://kb.askmonty.org/en/hibernate-reverse-engineering-wizard-with-mariadb/

(connect to database and have permission handling...) mysql_select_db ... select the schema being used mysql_query ... execute a query command (SQL QUERIES) mysql_fetch ... get a row mysql_num_rows .. get number of rows now the nosql... mariadb_handler_socket_openindex( handler socket parameters ) mariadb_handler_socket_query mariadb_handler_socket_fetch mariadb_handler_socket_close mariadb_memcache_get mariadb_memcache_set ... this make mariadb a sql/nonsql database with a single user/permission schema, and a nice language set (SQL, handler socket, memcache, redis, drizzle, hadoop, mongodb or others...) in this case we can use the mysql protocol, but instead of sending a QUERY command, we send a "MARIADB" command, and a new parameter telling what mariadb command it is, this can be used with mysql/mariadb/percona, when used with others database probably the database will report a wrong command message but we can contact mysql to reserve a command id to "others uses", and have compatibility with any mysql fork... but the point is... instead of many connections (3-> mariadb, handler socket write, handler socket read, or 2 -> mariadb, memcached) we have only one 1-> mariadb comments are wellcome, any idea why not implement this instead of many different protocol libs? -- Roberto Spadim

[Maria-discuss] new kind of plugin
by Roberto Spadim 17 Aug '13

17 Aug '13

Hi guys, I was thinking about a new kind of plugin, a field type plugin... i think it's a relative interesting idea... about sintax: ALTER TABLE table ADD field PLUGIN("plugin_name","version","field_type","parameters") NOT NULL/NULL DEFAULT 'something' AUTOINCREMENT, etc.. an example... ALTER TABLE table ADD field PLUGIN("crypt","1","somecrypto","size=255") NOT NULL DEFAULT 'something' internally (to storage engine) this kind of data will be saved as blob (for example), and to client side it will be a blob too when i use: insert into table(field) values ("some text"); and select * from table i will get "some text" but internally (at filesystem) the value is save as a crypto of "some text" --- other idea is compress ADD field PLUGIN("crypt","1","compress","size=255") NOT NULL DEFAULT 'something' internally it will be saved as varchar(255), when i execute insert it will compress the value and when i select it will uncompress the value the parameters for this new field type is: PLUGIN(plugin name, plugin version, plugin field name, parameters) plugin name is the plugin name... plugin version is important to execute alter table, or when using diferent kind of plugin versions we could know what version is being used and execute a automatic alter table for example... plugin field is the type of field in this plugin parameters are parameters for plugin values another idea is a enum with external table... ADD field PLUGIN("external_enum",'1','enum','table=database.table,id=field_id,value=field_value') it will execute a SELECT internally to table "database.table" and return the id/value of that table id is a bigint/int/mediumint/smallint/tinyint value (like enum index) and value is a string value (varchar,char,longtext,text) to storage engine will be used a bigint, for user it will be used as a enum() field ------ thre's more examples with interesting things, like expand opengis, or add others kind of field types, but the main idea is create a plugin interface for field types what you say guys? bye =) -- Roberto Spadim

Hi All. I have: - one devel application server with php53-mysql-5.3.27-1 MariaDB-compat-5.5.32-1.x86_64 MariaDB-common-5.5.32-1.x86_64 MariaDB-shared-5.5.32-1.x86_64 MariaDB-client-5.5.32-1.x86_64 - one devel database server with MariaDB-compat-5.5.30-1.x86_64 MariaDB-server-5.5.30-1.x86_64 MariaDB-common-5.5.30-1.x86_64 MariaDB-shared-5.5.30-1.x86_64 MariaDB-client-5.5.30-1.x86_64 When I try to make a connection from devel to database server with php mysql_connect function then when I am using: - user with local authentication: connection is ok; - user with pam/ldap authentication I get error "Client does not support authentication protocol requested by server; consider upgrading MariaDB client error 1251" When I use mysql command on application server I can connect to the database server with both users, so only php does not work. Have you got similar issues? Any clues anout how to solve the problem? Best regards, Rafal Radecki.

[Maria-discuss] New Question: Timestamps are different
by AskMonty KB 14 Aug '13

14 Aug '13

Hello, A new question has been asked in "Replication, Cluster, & Multi-Master" by confidus: -------------------------------- I am in the very early stages of testing out our Galara cluster with innodb databases. I have a tool that is comparing data against each node on the cluster and I have found that timestamps seem to be the only thing that is inconstant and by exactly 5 hours. I have a record in a Galera cluster that has a field with date time. I took one database and started comparing each table (one by one). I had several thousand records with different timestamps. An example is 2013-07-03 11:13:59, but another server, the date time is 2013-07-03 16:13:59. I would suspect that the times would be synced everywhere exactly the same. If I run a "SELECT NOW();" on all four servers at the same time, I see: +---------------------+ | NOW() | +---------------------+ | 2013-08-13 14:59:51 | +---------------------+ +---------------------+ | NOW() | +---------------------+ | 2013-08-13 14:59:51 | +---------------------+ +---------------------+ | NOW() | +---------------------+ | 2013-08-13 14:59:51 | +---------------------+ +---------------------+ | NOW() | +---------------------+ | 2013-08-13 14:59:51 | +---------------------+ If I run a select @@global.time_zone, @@session.time_zone on all four nodes in the cluster, I also see +--------------------+---------------------+ | @@global.time_zone | @@session.time_zone | +--------------------+---------------------+ | SYSTEM | SYSTEM | +--------------------+---------------------+ And if I enter date on all 4 machines, the time matches just fine. I have checked other non erip databases (some very large databases) and things are correct within those systems.
