Question

Can DataGate's IBM i DG8_VCATxx library be cleared, or otherwise have old objects removed? There are over 11,000 objects in this library, some dating back to 2012. Please help!

Answer

Yes—it is OK to use CLRLIB with the DG8_VCATxx library. That will remove all objects to which the current user has delete authority. However, do this when there aren’t any active users—otherwise current users will immediately get a non-responsive app and those jobs will lock-up and need manual attention to remove.

Other information

The DG8_VCATxx library (where xx is your system's DataGate version number) helps accelerate the retrieval of file definitions by caching them for DataGate.

Under normal circumstances you don't want to clear this library because it does significantly improve DataGate performance. However, there may be times where it has acquired a number of unused or stale cached file definitions or if your disk space is running so dangerously low that you need disk space. In that case, you can use CLRLIB (as explained above) to clear this library.

You may also need to clear this library is you get this error message:

Acceler8DB Error: Corrupt file defininition cache member.
