The following problems are seen in a MP application with 15 hosts on a WAN:
The application typically boots without a problem.
- Sometimes, however, nodes become partitioned without any apparent cause.
- Sometimes "tmadmin reconnect" fails, even though the partitioned node is alive.
- Sometimes "tmshutdown -k KILL -y" causes most nodes to be partitioned. After this happens, the only way to shut down the partitioned nodes is to kill the Tuxedo processes and clean up the IPC.
- As a consequence of these failures, it's frequently impossible to unpartition nodes that have become partitioned.
- Sometimes the DBBL appears to be hung. Other times, it appears that the DBBL is not processing its message queue.
