QACX Files In The iSeries IFS
Read Time:46 Sec
We had almost 8000 QACXxxxxxx files in our tmp directory in the IFS on our System i Enterprise server. They didn’t seem to be causing any harm, but they were definitely taking up space.
According to Oracle in the docs below, these files are temporary and should be cleaned by the system when a UBE completes processing. So far, since I have been monitoring, the UBEs are completing successfully, but the QACX files are remaining in IFS.
According to the Oracle doc, these files can be deleted…preferably when E1 services are down to ensure that you do not delete something the system is using.

Great article, Stewart. I just ran into this today for a customer, in fact.
FYI, the link to the Oracle article above does not work.
Great to hear from you Winston!
I’m glad this helped you.
It doesn’t surprise me that the My Oracle Support document is in a different location. This post was written almost 17 years ago. 😄
I’ve updated it with some additional supporting documentation. 😊
