DB2 - Problembeschreibung

Problem IC98278 Status: Geschlossen

TOOLS THAT USE THE DB2READLOG API MAY SUFFER BAD PERFORMANCE IF AN OLD LSN
IS REQUESTED

Produkt:
DB2 FOR LUW / DB2FORLUW / A10 - DB2
Problembeschreibung:
In the newer releases of DB2 ( v9.8, v10.1, v10.5 ) if a older 
log file is requested to be read DB2 has to read all the files 
sequentially back up to the old file to verify the correct file 
is chosen. Depending on the number of log files that need to be 
retrieved, and the time required to retrieve each log file, this 
can be a lengthy process where, although the application is 
making progress, it may appear that the application is hung and 
not doing anything.
