RP/TUX 6.5, 6.51,8.0,9.1 - Application Server Process IPC Queue Leak After Tuxedo Shutdown
Last updated on JANUARY 19, 2018
Applies to:Oracle Tuxedo - Version 6.5 to 9.1
Information in this document applies to any platform.
Customer has a big MP application. As a routine procedure, they have to shutdown/restart some groups. Since some servers may still be in service at the time of shutdown, they may take a long time to finish tpsvrdone(). The customer usees tmshutdown with -w option to perform the shutdown operation. As a result, some application servers ipc queues are not being removed, these queues remain to take ipc resources without being referenced by Tuxedo. The corresponding Tuxedo servers are removed from bulletin board. The problem seems related to the fact that servers are being killed and the restart server is being launched during the shutdown. The problem is pretty systematic on the client site, so every day, ipc queues containing data (or not) are found left on the system, exhausting the system resources in the long term.
