Increase operating system threads

HP-UX only – Beginning with version 12.5, Replication Server uses operating system threads instead of Open Client/Server threads™. This requires the operating system kernel to allocate many more threads per process than previously. However, because many HP-UX systems have relatively low default limits on the number of threads per process and total number of threads per kernel, Replication Server can report the following error message:

F. 2002/05/28 12:23:37. FATAL ERROR #1030 ?(?) - /errhand.c(730)
Open Server error: Error: 16361, State: 0, Severity 20 --
'CreateEvent() failed in srv__spawn_thread'.
T. 2002/05/28 12:23:37. (2): Exiting due to a fatal error

To prevent this error message, increase the value of max_thread_proc to 256, and the value of nkthread to 2048 in your operating system:

  1. Log in as the superuser (SU), and go to the root directory.

  2. Start sam.

  3. In sam, select “Kernel configuration.”

  4. Select “Configurable parameters.”

  5. Scroll down to “max_thread_proc.

  6. Increase the value of max_thread_proc.

  7. Select Actions | ProcessNew Kernel to rebuild the kernel.

  8. Restart the system.
