We have as 2064-2C5 with 3 LPARS weighted as follows: SYSA - prod 415 uncapped 5 cpus online SYSB - dev 75 capped 5 cpus online SYSC - sysprog 10 capped 2 cpus online
We have a single TCB CICS region running on SYSA that "maxes out" at about 83% (415 / 5 engines) at most peak times. (CICS sometimes also goes max tasks due to CPU constraint when SYSB is fully loaded. We then change the weight for SYSA to over the 415 for a certain amount of time to let it catch up.) Our SYSB is suffering lately for CPU in the above configuration. At times, SYSA is not maxed out and we would like to give SYSB more CPU dynamically. We are worried, however, that by raising the weight or uncapping SYSB we may cause the high CPU CICS region to suffer on SYSA. If, for instance, we took off the cap on SYSB and it went to a weight of 100, then SYSA would get only a 390 weight. The high CPU CICS region would possibly suffer because of its single TCB architecture. True? Thoughts? We are also thinking of alternate configurations for the plex involving taking engines offline to certain LPARS. Any help would be appreciated. ---------------------------------------------------------------------- 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
