Sybase 15 manual Increase operating system threads

CHAPTER 1 Before You Begin

If your operating system requires patches, install them before you install

Replication Server components.

Note Do not use a patch that is earlier than the version suggested for your operating system. If a patch has been superseded by a newer patch, use the most recent one.

Solaris:

To list all currently installed patches and display the operating system version level, enter:

showrev -p

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.
