This is a pretty average month with a few HIPERs and a few interesting performance APARs.
Last month I highlit this OPEN APAR:
PH57664: POOR PERFORMING APPLICATION THAT HAS A COMMIT OR ROLLBACK SQL STMT AND PRECOMPILED BEFORE V8 DUE TO UNNEEDED CCSID CONVERSION – Here you must try and find any of your packages from SYSIBM.SYSPACKAGE that were pre-compiled using a pre-Db2 V8 load library. The only way I have found to do this is to actually look into every DBRM on line one at position 80. Here you will see the pre-compiler version stored. If it is less than „L“ than you have this problem. Here’s an example:
In the DBRM header line you can see the IBMREQD flag in position 79, in this case „L“ as the SQL has no new dependancies, and the pre-compiler version „Q“ in position 80 is Db2 12. If you have any here less than „L“ then, sadly, it requires a precompile,compile/assemble,link & bind to fix the problem. I cannot see how an APAR can fix this! I sincerely hope no-one actually has any…
Much to my happiness it got CLOSed with HIPER PTF UI94517 !
HIPERs:
PH57433: SYSAIDB.SYSAICOLUMNCONFIG.MAX_DATA_VALUE_LEN MAY BE INACCURATE, ABEND0C4 DSNSVBK+013EA OR DSNXOAIF+03146 FOR SQLDI QUERY
PH57473: BROKEN DATA PAGE CAUSED ABEND04E RC00C90101 AT DSNIBHRE ERQUAL0C33 WHEN RUNNING A COPY UTILITY. 23/10/13 PTF PECHANGE
PH57664: POOR PERFORMING APPLICATION THAT HAS A COMMIT OR ROLLBACK SQL STMT AND PRECOMPILED BEFORE V8 DUE TO UNNEEDED CCSID CONVERSION
Interesting for RTS:
None.
RUNSTATS:
None.
Query performance:
PH56737: ABEND0C4 RC10 IN DSNXOTS1+04DA4 CAN OCCUR FOR A QUERY CONTAINING GROUP BY OR SET FUNCTION DISTINCT AND R-SCAN IS CHOSEN FOR TABLE
PH56742: UNEXPECTED ACCESS PATH FOR AN UPDATE STATEMENT ON VOLATILE TABLE WITH AN UNIQUE INDEX WHICH CAN MATCH ALL PREDICATES
IAG2:
None.
FIT/FTB:
PH57537: FTB ACTIVATED BUT NO INDEX WAS LOADED IN MEMORY
Now come the three tables containing all the APARs.
First are the Real-time Statistics APARs – If the RTS are incorrect then any Utility generation or Access path decision based upon them could also be incorrect.
Next are the RUNSTATS APARs – If RUNSTATS causes data problems this, obviously, can have a major impact upon performance after the following BIND, REBIND or dynamic SQL PREPARE.
Finally, come the SQL PERFORMANCE APARs – In here are all relevant performance APARs as well as HIPERs that do not fit into any other category. A HIPER warrants a check in all cases.
All three tables have the same headings:
APAR – The assigned APAR for the problem.
CLOSED – This is the date in YYYY-MM-DD format when the APAR was closed.
STATUS – This column is NEW, NEW & CLOSED, CLOSED or PE xxxxx. A PE means that this APAR went PE and the xxxxx is the corrective APAR.
Db2 12 – If the PTF is for Db2 12 then it is listed here else N/A or OPEN.
Db2 13 – If the PTF is for Db2 13 then it is listed here else N/A or OPEN.
HIPER – Contains Y if the APAR is a HIPER. Can also contain (Y) if it is OPEN but presumed to be a HIPER, else it is blank.
Description – This is the APAR description taken from the header text. Sometimes I add extra details if the description is misleading or incorrect.
Note: If the PTF column has OPEN it means that the PTF was still open when the last check was done; of course it could have been Closed since this post was updated. Every year all APARs that were closed over two years ago are deleted.
