Problem IC98804
|
Status: Closed |
TOOLS THAT USE THE DB2READLOG API MAY SUFFER BAD PERFORMANCE IF AN OLD LSN IS REQUESTED |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
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. |
