Occasionally, customers utilize the MIM DISPLAY CFSIZE to ensure their control file sizes are within acceptable capacity; for those who need to increase their list structure sizes, MIM provides an instruction set to make this change dynamically.
Release : 12.5
Component : MIA, MIC, MII, MIM
To perform this scenario, first issue the MIM DISPLAY CFSIZE command:
Control file size required for current ENQ workload: 27274 Kb
Control File Size required for peak ENQ workload: 31561 Kb
E File Cur Size Rec Sz(Kb) Name
- ---- -------- ---------- --------------------------------------------
* 00 25000 42435 MIMI#TABLE00
01 30000 42435 MIMI#TABLE01
In the above case, it's recommended the site increases their control file list structures using the method detailed below.
While MIM provides full support for system-managed rebuild of coupling facility structure control files, the MIM Programming Guide does state:
"[that] the MVS REBUILD command [cannot be used] to change the size of a MIM list structure. Instead, use the MIM DEALLOCATE and ALLOCATE commands".
