Apply or Commit Filesets in AIX

When we installed filesets on a AIX box either we commit them or apply them . Then what does these commit or applied means ? Actually When fileset updates are committed, the older versions are removed whereas when fileset updates are only applied, the previous version is saved. So Applying fileset rather than committing them has advantage of roll back new updates in any unlikely event by rejecting them. Later once we are sure that we are not going to back out the new filesets, we can commit them, which will save you some disk space.
Using lslpp -l |grep -i Applied command you can check Applied filesets in AIX

webmanul01:/> lslpp -l |grep -i Applied

Similarly Using lslpp -l |grep -i Commit command you can check Committed filesets in AIX

webmanul01:/> lslpp -l |grep -i Commit |head

To Commit filesets using smitty : smitty commit
webmanul01:/> smitty commit



Using command

#installp -c all

Here in the above example I have committed all Applied Fileset in AIX. You can rather select individaul fileset also
