[EP-tech] Re: mysqldump problem with cachetables



Hi Paolo,

I run the cleanup_cachemaps, but it only removed one orphaned table, leaving me with 942.
Would you know why I have so many cache tables?

Thanks.
Regards,
Malcolm.

Hi Malcom,

you might use --force to "force" mysqldump to continue the backup.

Before starting the backup, you might use "epadmin cleanup_cachemaps *repository_id*" command to drop orphaned cache
