PI40569: CO-REQUISITE TO IMS PA V440 APAR PI40457 AND FOUR OTHER ISSUES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• These issues are being addressed:
  1. Co-requisite to IMS PA APAR PI40457 - RLDS support in DBRC
     options in System Definitions.
  2. If certain log record types (IMS X'4E' - Monitor) are
     extracted by IMS PI the records may be subsequently
     corrupted in processing the extract data set.
  3. Support IMS Service updates which may modify the contents or
     construct of IMS, Connect and other log record types.
  4. Forward fit of IMS Problem Investigator V230 APAR PI41839
     (Random abends {eg S0C4, S0C6} processing IMS V13 log with
     records containing compressed data).  ABEND0C4 ABENDS0C4
                                           ABEND0C6 ABENDS0C6
     Another symptom of this found: ABEND0C1 in ALZ991 ( ALZ99D )
     at x'4B9A' when processing compressed data.   ABENDS0C1 S0C1
  5. Filtering on DB2 LUWID may fail under some circumstances.
     If a Filter for a specific DB2 log code (e.g. DB2 0020 - UR
     control) contains a condition defining a specific LUWID then
     no results will be returned, even if there are records that
     validly satisfy the criteria. The composite key containing
     the LUWID component parts used for comparison checking was
     not being constructed in the case of specific record codes,
     only in the case of CODE=ALL being used.

  This APAR addresses the following issues:
  1. Co-requisite to IMS PA APAR PI40457 - RLDS support in DBRC
     options in System Definitions.
  2. If certain log record types (IMS X'4E' - Monitor) are
     extracted by IMS PI the records may be subsequently corrupted
     in processing the extract data set.
  3. Support IMS Service updates which may modify the contents or
     construct of IMS, Connect and other log record types.
  4. Random abends (eg S0C4, S0C6) processing IMS V13 log with
     records containing compressed data.
  5. Filtering on DB2 LUWID may fail under some circumstances.
  

Problem conclusion

• The following changes have been made for the above issues:
  1. System Definitions may be shared between IMS PA and IMS PI,
     PI40457 introduces RLDS support into DBRC Options in IMS
     PA V4.4, this option must also be supported in IMS PI V2.4.
  2. IMS X'4E' Monitor records are de-blocked and require
     pre-processing in IMS PI for an online Monitor session.
     If these records are subsequently extracted and the extract
     is processed by IMS PI the pre-processing of these records
     is no longer required. Extracted records must be identified
     on input and flagged as not requiring pre-processing which
     may corrupt the extracted record.
  3. Update Knowledge Modules impacted by IMS Service changes.
  4. The IMS x'9904' record may be truncated at any point and a
     continuation record created. If the truncation occurs in a
     block of compressed data, which is then passed to the Data
     Compression and Expansion routine to be expanded with the
     original non-truncated length specified, the expansion
     fails but during the process unrelated storage may be
     overlaid at random causing subsequent abends to occur.
     In processing for the IMS x'9904' record, before calling
     the Data Compression routine to expand compressed data the
     supplied length must be validated against the actual data
     length to ensure truncation has not occurred.
  5. If a Filter for a specific DB2 log code (e.g. DB2 0020 -
     UR control) contains a condition defining a specific LUWID
     then no results will be returned, even if there are records
     that validly satisfy the criteria. The composite key
     containing the LUWID component parts used for comparison
     checking was not being constructed in the case of specific
     record codes, only in the case of CODE=ALL being used.
