DB2 - Problembeschreibung

Problem IC96452 Status: Geschlossen

HADR STANDBY CAN BE SLOW DUE TO INDEX MAINTENANCE

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
HADR standby can slow down due to index maintenance.  The reason 
is due to the fact that lot of the index page split, page merge 
and other records generated in the log are mostly tablespace 
blocking records which cause them to run serially on the same 
tablespace. 
 
Some log records related to create/reorg index have also had 
their blocking level improved to allow for faster replay on the 
standby.
