Problem IC81601
|
Status: Closed |
A MULTITHREADED CLIENT RUNNING WITH WLB ENABLED AND CONNECTED TO A PURESCALE MEMEBER MAY TRAP. |
| product: |
DB2 CONNECT / DB2CONNCT / 970 - DB2 |
| Problem description: |
A multithreaded client running with WLB enabled and connected to
a pureScale cluster may trap if two threads are
accessing/modifying the server list cache at the same
time(cfgcache/srvlst.xml). This is timing dependent - It can
hit this as early as two minutes into a run and as late as 40
minutes. The likelihood of hitting this is increased when there
are concurrent connection attempts in progress. |
