Error description
An S0C4 abend occurs in DFHZRSY1 (640 base) +x'0A96'. R9 was supposed to point to a TCA, but in the originating problem record, it instead pointed to an RPL for a terminal. APAR opened for additional investigation. Abend S0C4 ABENDS0C4 0C4 THREADSAFE KIXOTE

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: DFHZRSY1 abend0C4 at X'0A9A' because * * R9 points to an RPL instead of the TCA. * **************************************************************** * RECOMMENDATION: * **************************************************************** DFHZRSY1 was called as part of the activate scan process for a 3790 userprogram device. DFHZRSY1 was called after the BIND because recovery was required. If this, in turn, calls DFHZSES or DFHZGET, R9 is used to address the RPL from TCTERPLA. R9 is later reused to address the TCA, but now holds the address of an RPL causing an 0C4 abend at X'A9A' in DFHZRSY1 in routine zrsy_module_exit. This in turn causes CICS to fail with DFHSR0601 DFHME0116 program interrupt with system task TCP in control. Additional keywords: msgDFHSR0601 SR0601 0601 LU61 LU6.1 TCTEICRY TCTECRY
Problem conclusion
DFHZRSY1 has been altered to restrict the base register used for the TCA to R12.
