Workaround to clear up space:

To clear out this directory do the following. It will recreate the directory and repopulate as CA Performance Center contacts the various data sources.

Note that until this is complete, you may see errors on views regarding invalid ribcache syntax, these will go away as the cache is repopulated.

a) Stop the CAPC services as noted here:

You do not need to stop mysql

b) Rename the ribcache directory:

cd /tmp

mv ribcache ribcache.old

or move to a location with sufficient space.

c) Start the CAPC services as noted here:

d) Once the cache has repopulated you can remove the renamed/moved ribcache directory,
