PER Activation/Deactivation Recovery

In general, if a problem is encountered at any point in the program event recording (PER) activation/deactivation process, the modules listed in Table 1 try to deactivate PER completely and record diagnostic information.

Table 1. Summary: Modules that try deactivate PER and record diagnostic information
Module Name Diagnostic Information Recorded
IEAVTGLB The system writes a logrec data set error record. The system writes a summary dump, which contains the following:
  • The FRR parameter list, mapped by FRRWA in module IEAVTGLB.
    Note: The logrec data set also contains the FRR parameter list.
  • The communication vector table (CVT) data area.
  • The SHDR data area.
  • The SCE/SCVA data areas for the non-IGNORE PER trap.
  • The model prefixed storage area (PSA) data area.
  • The physical configuration communication area vector table (PCCAVT) data area.
  • The ASCB being processed by IEAVTGLB.
  • The name of the job running in the address space being processed by IEAVTGLB.
  • The physical configuration communication area (PCCA) data area.
  • The PER control registers: 9, 10, and 11.

The system issues message IEA414I and requests percolation if IEAVTGLB encounters a recursive problem.
IEAVTJBN The system:
  • Writes a logrec data set error record.
  • Writes a dump.
  • Issues message IEA422I to indicate that the status of PER in the system is uncertain.
IEAVTLCL The system writes a logrec data set error record. The system writes a summary dump, which contains all, or some, of the following:
  • The FRR parameter list, mapped by FRRPARMS in module IEAVTLCL.
  • The CVT data area.
  • The SHDR data area.
  • The SCE/SCVA data areas for the non-IGNORE PER trap.
  • The ASCB for the address space in which IEAVTLCL was running when the error occurred.
  • The name of the job in the address space.
IEAVTPVT The system writes a logrec data set error record. The system writes a summary dump, which contains all, or some of the following:
  • The FRR parameter list mapped by structure WORK24.
  • The CVT data area.
  • The SHDR data area.
  • The SCE/SCVA data areas.
  • The PCCA data area.
  • The PER control registers: 9, 10, and 11.
The system issues message IEE414I and requests percolation.
