Checking & Repairing Databases

It's important to run a database check if you ever have an unexpected server outage or if you suspect table corruption.

1. Shutdown modperl:

 /data/wre/sbin/wreservices.pl --stop modperl

2. Run the check with auto-repair:

mysqlcheck -c -v -p --auto-repair --all-databases

3. Restart modperl:

 /data/wre/sbin/wreservices.pl --start modperl

You will get a report at the end of what tables were repaired and the status of the repaired tables. You may also need to shutdown SPECTRE and any other applications that are trying to connect to the database. See the MySQL manual for more details.
