We have upgraded our OS/390 TSM server to 4.2.1.9. This appears to have resolved our performance problems. I would like to thank Bill Colwell, John Naylor, and Brian Nick for their advice and assistance.
The first time we started the server it reported that it was upgrading its database, even with the relatively small change in level. We upgraded to 4.2.1.0 before going to 4.2.1.9. The 4.2.1.0 upgrade was packaged as SMPE input. SMPE is the standard OS/390 software maintenance tool, which keeps track of installed levels, verifies that prerequisite products are installed, and so on. The 4.2.1.9 upgrade was delivered as three replacement files with no provision for SMPE tracking. Tivoli has made choices that have led to essentially interchanging the roles of maintenance releases and patches. Sites that need stable code frequently end up running patches for long periods. Given this reality, I find it extremely annoying that patches are not packaged as SMPE input.
