[Maria-discuss] ALGORITHM INPLACE for 10.0.24-MariaDB
by Rhys.Campbell＠swisscom.com 04 May '16

04 May '16

Hi All, For the following statement... ALTER ONLINE TABLE dom_audit_event ENGINE=INNODB, ALGORITHM=INPLACE; I can still see that MariaDB is still using the value of tmpdir. We have this set to tmpfs on some of our servers and this causes some ALTER statements on big tables to fail. It was my understanding that if you specified INPLACE then the statement would fail if this was not possible. Am I missing something? Cheers, Rhys

[Maria-discuss] New Question: Can't connect to MariaDB through mysql command line client
by AskMonty KB 02 May '16

02 May '16

Hello, A new question has been asked in "MariaDB Community" by chuck_lyon_g. Please answer it at http://mariadb.com/kb/en/cant-connect-to-mariadb-through-mysql-command-line… as the person asking the question may not be subscribed to the mailing list. -------------------------------- I have installed the xampp stack which now includes MariaDB. I have been connecting to it with phpMyAdmin and php scripts through Apache as localhost. This all works with no problem. Today I tried to use the mysql command line tool and got the following error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory") I checked, and indeed that path does not exist. I did, however find the following path: /opt/lampp/var/mysql/mysql.soc Is it possible that the xampp stack installs the database files in a non-standard location and I need to tell mysql about the change? If so, how? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/cant-connect-to-mariadb-through-mysql-command-line…

[Maria-discuss] New Question: JDBC driver configuration error

Hello, A new question has been asked in "MariaDB Community" by Intrinsic. Please answer it at http://mariadb.com/kb/en/jdbc-driver-configuration-error/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I am attempting to connect to MariaDB from a command line Java program. I am getting the "no suitable driver found" error. I am using the mariaDB Type 4 JDBC driver, the JDK 1.8, Windows 10. I have added the maria driver to the lib directory of the JRE, and added this directory to the PATH and CLASSPATH environment variables. I can connect to the mariaDB database using DBVisualizer, when I manually point the configuration of DBVisualizer to the maria driver, so I know that the driver works fine. Here is the Java code: Connection con = DriverManager.getConnection("jdbc:mariadb://localhost:3306/DB?user=root&password=myPassword"); and the error C:\Users\Documents\VTK\Dev>java -cp . VTK3 java.sql.SQLException: No suitable driver found for jdbc:mariadb://localhost:3306/DB?user=root&password=myPassword at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at VTK3.main(VTK3.java:38) Thanks -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/jdbc-driver-configuration-error/
