Thanks for the responses. I was concerned about the JES spool too but we don't share spool between LPARs.
When I went from OS/390 2.9 to z/OS 1.4, I ran the 2.9 JES until after the OS was considered stable. Then I did the ACTIVATE and followed that a few weeks later by coming up with the new JES and the old spool. Spool didn't even know I was there. I didn't do an offload-reload because I've heard too many horror stories about corruption in spool files. A friend did an upgrade wth offload-reload and spent most of the following week trying to recover from the damage. It never was quite right and management just decided to deal with the loss. Thanks for the tips about TCP/IP and LE parms changing. I've been getting console messages about things getting changed in a future release. Guess now is the time to pay closer attention. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
