Issue:
User received DBG55166E TESTVER DOESN'T MATCH trying to select the db2 subsystem from main panel
 
Resolution:
The mismatch error DBG55166E normally denotes that the level of code is not the same between the Insight elements (PC task, DC task, IDUIPRMS, etc). Make certain that the PC started task is at the same level of code as the DC. If you are currently running two different PC tasks from two different releases like  R18 and an R19 then make certain they have different PCSSID settings, and that the IDDCPRMS and IDUIPRMS members point to their respective PCSSIDs. You cannot mix releases of Insight for DB2. Everything has to be at the same code level- PC, DC, VTAM UI, INSIGHT clist, etc. Also make sure that you're invoking the correct CLIST you're pointing to the correct libraries.
For this case  the wrong logon proc was being used. User found that the R19 PC and DC procs were over written by a proclib backup causing the mismatch. Correcting that resolved the problem
