Hi
What would be the impact of this file on the performancce of the system.
When this file was around 2GB the system appeared to have hung and when this
file was cleared things were back to normal.
But there was a reporting user who says their reports are running faster
after the pacct file was cleared. With my limited understanding of what
paacct file is, I interpreted this as follows.
Because the pacct file was growing, the kernel cpu usage was growing and
when this file hit 2GB, then the system was hung. So all the while, the file
has been growing there would have been performance degradation. Once the
file is cleared, the kernel cpu % age reduced and this cpu time was
available for other processes.
Any thoughts or suggestions?
Thank you
