Symptom Description INT-PIPs
System or
subsystem runs
slow. The system or the subsystem is not processing at its normal
speed (for example, QBATCH). “INT-PIP20 Performance
Problems” on page 339
If the symptom for the intermittent problem you have is not listed, go to “Failing
Area INT-PIP Table”.
Failing Area INT-PIP Table
Use this table only if you do not have an SRC or cannot find your symptom in the
“Intermittent Symptom Table” on page 20.
Note: Before performing any INT-PIPs in Table 2, first perform all of the steps in
“General Intermittent Problem Checklist” on page 16 for all failing areas.
1. Under Failing Area , find the area of failure.
2. Look down the column for the area of failure until you find an X. Look
across to the
INT-PIP column and perform the INT-PIP indicated.
3. If the INT-PIP does not correct the intermittent problem, continue down
the column for the area of failure until you have performed all of the
INT-PIPs shown for the failing area.
Although an INT-PIP may correct the intermittent problem, use your best
judgment to determine if you should perform the remainder of the INT-PIPs
shown for the failing area.
