Problem IC79907
|
Status: Closed |
DB2CFIMP <FILENAME> UPDATES DBM CFG PARAMETERS INCORRECTLY WHEN VALUES SET TO AUTOMATIC; CLIENT CONNECTIONS WILL HANG |
| product: |
DB2 CONNECT / DB2CONNCT / 970 - DB2 |
| Problem description: |
If original db2 get dbm cfg shows
MAX_CONNECTIONS = 100 AUTOMATIC
MAX_COORDAGENTS = 200 AUTOMATIC
NUM_POOLAGENTS = 200 AUTOMATIC
when you export the configuration using
db2cfexp filename backup
the filename will contain:
MAX_CONNECTIONS=AUTOMATIC
MAX_COORDAGENTS=AUTOMATIC
NUM_POOLAGENTS=AUTOMATIC
When this file is then used with
db2cfimp filename
The result in the dbm cfg shows:
MAX_CONNECTIONS = 0 AUTOMATIC
MAX_COORDAGENTS = 0 AUTOMATIC
NUM_POOLAGENTS = 1 AUTOMATIC
Any connections to the database will hang waiting for an agent. |
