CHAPTER 1 Before You Begin

Installation Guide for UNIX

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 If a patch has been superseded by a newer patch, use the most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.

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.
