DPF CATALOG NODE FAIL DEACT APP HUNG IN LOCALDEACTIVATE IN TERM LOG SYNC. SIMILAR TO APAR IC75211 (9.5) and IC74901 (9.7) |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
Similar to APARs fixed in 9.5FP8 (IC75211) and also included in
9.7FP5 (IC74901).
In DPF, when the catalog node fails, a CNF deact app is spawned
to deactivate the database and clean up the database. If it is
the last app, it will send a term log sync to the catalog node.
This term log sync is hung waiting for a reply from the catalog
node when it should have failed with -1229.
On Version 9.7FP5, DB2 might experience a partition hang with
the following symptoms:
There is an agent thread that is in in the process of
deactivating the database in the hung partition (likely -1229
errors will be received on attempting to connect to that
partition)
Database partition is hung with
