we are using aix 5.3 and we notice that the filesystem /usr is almost full. we have an oracle database running on the server.what are the cause why this filesystem is almost full.what should we do to free some space on this filesystem beside increase the size?thanks

Hi,

commit all your applied filesets and you will see the usage of /usr going down.
Each time you apply a new fileset, the previous version is kept - if you have multiple versions of the same fileset this can occupy a lot of space. This is especially true after applying maintenance levels ...

Kind regards

thanks zxmaus for the reply.what is a fileset?is it under unix or oracle?

A "fileset" in AIX terminology is a software package to be installed. It consists of files to be copied somewhere along with some methods to be carried out at some stages of the installation/deinstallation.

You might want to do a search for "fileset" or "installp" here to find out more about the installation process and related information. You might also be interested in this thread and this thread for some related information about software management in AIX.

I hope this helps.

Use sth like that :

du -am /usr | sort -nr | head

to find out what file/dir keep space.
