Status: Closed |
ADDITIONAL CALLS IN AGENT BREATHING POINT CAUSE POOR PERFORMANCEIN LOAD UTILITY |
| product: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
Excessive looping in Agent Breathing Point causes poor
performance in the LOAD utility and may make the utility appear
to hang.
To identify, threads may be in this stack:
0x0900000068096D0C sqldReadTemp__FP13SQLD_DFM_WORKl + 0x38C
0x09000000677F8E94 @114@sqldFetchNext__FP13SQLD_DFM_WORK + 0x18

| Local Fix: |
We can set DB2_ROWCOMP_TEMP=disable=util and it will avoid this
area of looping. Please keep in mind that setting this variable
will make some changes in the internal compression used in
utilities such as LOAD and REORG. While their overall
performance will be the same, setting this variable will mean
that they require additional TEMP space. |
