Hello. Has anyone upgraded from Unidata 7.3.3 to 8.2.1 and saw a large increase in overall system memory usage? Especially in an AIX environment?
We upgraded and went from 50 gig of real memory and 16gb of paging, with 1% paging to currently 130gb real memory and increased paging to 80gb as a precaution after the system ran out of memory the days after the upgrade. We had to add memory and paging space on the fly after the upgrade.
We saw smaller increase on 3 other servers, about 50%, and the server with 990 users, over 850 logged in routinely, we had the extreme memory usage numbers above.
Here is our top ten processes currently:
