[Maria-discuss] Reg custom port for maxscale binlog router
by Karthick Subramanian 29 Aug '16

29 Aug '16

Hi all, When I try to configure maxscale for binlogrouter, I noticed that documentation examples using port as 5308. When I try to configure similarly, it says, 111 connection refused or unable to connect master from maxscale. I have enabled the port in centOs7 using firewalld on both master server as well maxscale server: firewall-cmd --add-port=5308/tcp But still,I couldn't able to establish connection from maxscale server to mariadb server(master): mysql -u maxscaleoper -h ip:ip:ip:ip --port 5308 -p ERROR 2003 (HY000): Can't connect to MySQL server on 'ip:ip:ip:ip' (111 "Connection refused") Can anyone please help me on how to resolve this error. Because of this error, I couldn't make maxscale up and running. Regards, Karthick S

Re: [Maria-discuss] Don't replicate procedures in the mysql database
by Federico Razzoli 29 Aug '16

You should keep those procedures in a different database, not mysql. Then you can avoid replication with replication filters: https://mariadb.com/kb/en/mariadb/selectively-skipping-replication-of-binlo… But first, be sure you understand what happens when you call the procedure on the master.

It's totally fine for maintenance procedures. See for example http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.MySQL.SQLRef… > set session sql_log_bin=0; create procedure... This is not scalable and sometime impossible: for the SUPER privilege, at Amazon RDS, it could break other slaves. _______________________________________________ Mailing list: https://launchpad.net/~maria-discuss Post to : maria-discuss(a)lists.launchpad.net Unsubscribe : https://launchpad.net/~maria-discuss More help : https://help.launchpad.net/ListHelp

[Maria-discuss] When using the getGeneratedKeys() method the keys are returned, but in which order?
by Péter Éberhardt 26 Aug '16

26 Aug '16

Hi, I want to insert multiple records into a table using one statement like this through jdbc: INSERT INTO demo (name) VALUES ('Jeff'),('Jones'),('Agnes'),...,('Wolfgang'); Then I want to get the generated ids with the getGeneratedKeys() method and match them to the inserted records but how can I be sure the method gives the ids in the same order as I listed the records in the statement? I can't find any related information in the documentation just the fact the method gives back those ids. DDL: CREATE TABLE demo (id bigint primary key auto_increment , name text); If this information would put into the document also then I can go with my implementation on this way. Thanks, Peter

[Maria-discuss] New Question: Locking/deadlocking on temp tables?
by AskMonty KB 26 Aug '16

26 Aug '16

Hello, A new question has been asked in "MariaDB Knowledge Base" by WebtrendsData. Please answer it at http://mariadb.com/kb/en/lockingdeadlocking-on-temp-tables/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hello - I am coming up to speed on MariaDB, I have a MS Sql Server and Hadoop background but we are starting to use MariaDB heavily. We have some queries that hit tables with mediumtext datatype columns. My understanding is these types of queries will always generate temp tables directly to disk (because of the text/blob types). I've confirmed our temp table engine is Aria. >From what I've read, in the mysql world, this situation would end up with a MyIsam table on disk, which does not have row locking, only table locking. I've tried looking for info on how Aria tables would handle this as I suspect we are getting deadlocks on these tables. Our application is reporting many database deadlocks, our entire database is all ExtraDB tables, yet SHOW ENGINE INNODB STATUS does not report any deadlocks, which leads me to think it is the temp tables. So I guess my question is, does the Aria engine do row locking? Is it possible to get a status similar to SHOW ENGINE INNODB STATUS? Please forgive me if this is painfully obvious or unclear (I'm still learning!), and thank you for your time. -Aaron -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/lockingdeadlocking-on-temp-tables/

Re: [Maria-discuss] Backporting bug fixes to 1.0?
by Justin Swanhart 26 Aug '16

26 Aug '16

Thanks for your armchair diagnosis, but I'm not "striking out" at anybody. I'm outraged by the behavior of MariaDB. I'm passionate about open source, since my whole life has been spent on it. I joined because the company is open source. What I found after I joined was a total lack of regard for it, and a lack of ethics. Would YOU knowingly ask a customer to install software with known vulnerabilities reported ten years ago? Would you ship open source that doesn't compile? Would you extort your current users of your product for bug fixes? If you answered yes to those questions then you don't have ethics either. --Justin Sent from my iPhone On Aug 25, 2016, at 1:15 AM, Jan Steinman <Jan(a)EcoReality.org> wrote: >> On 2016-08-24, at 06:22, Justin Swanhart <greenlion(a)gmail.com> wrote: >> >> I'm bipolar > > Seems more like Borderline to me.
