Configure ODBC

vim /etc/odbcinst.ini

Remove the '#' in front of each lines of the [MySQL] section Modify the 'Driver' line to set the correct driver

Example:

[MySQL]
Description     = ODBC for MySQL
Driver          = /usr/lib/libmyodbc5.so
Setup           = /usr/lib/libodbcmyS.so
Driver64        = /usr/lib64/libmyodbc5.so
Setup64         = /usr/lib64/libodbcmyS.so
FileUsage       = 1

Configure MySQL

vim /etc/my.cnf

Add these variables in the file under the [mysqld] section:

• log-bin
• server-id=[UniqueId]

The server-id needs to be a non-zero unique value (do not use 0). If you use the host redundancy feature, the value needs to be different on each host .

Add max_allowed_packet to increase the maximum size of binary blobs in the database. Make sure it is in the [mysqld] section AND [mysqldump] section

 max_allowed_packet = 200MB

Add below to remove database dependencies with DNS servers (**Applicable to TMG users only)

 skip-name-resolve

Add this to make sure the mysql logs don't get too big

 expire_logs_days=60

Example:

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
log-bin
server-id=1123476
max_allowed_packet = 200MB
skip-name-resolve
expire_logs_days=60
