When a CICS region is started with RLS initializing in it, the following error message is received:
TSS9410E UNKNOWN CLASSNAME (SUBSYSNM) FOR SVC (RACHECK ).
The SUBSYSNM resource class needs to be defined to the RDT in CA Top Secret via:
TSS ADD(RDT) RESCLASS(SUBSYSNM) RESCODE(xx) ACLST(ALL,READ,NONE)
Then own the resource and permit it to the CICS region acid via:
TSS ADD(dept) SUBSYSNM(cicsappl) TSS PER(region acid) SUBSYSNM(cicsappl) ACC(READ)
