Xprint F.A.Q. Document revision 10 (16.09.2008)

Page 20/89

E. Starting and stopping

E.1 How can I reduce the delay between a stop-start of Xprint ?

On a Xprint-Net configuration the port Xprint_db stays for a while in TIME-WAIT after the processes are already

gone. During this period Xprint can not be re-started, the message that is returned is: "XP000161: Database

public port open failed"

Following the platform, this period takes about some seconds, to several minutes on the Solaris operating system.

It is possible to reduce the period of TIME-WAIT by means of variable of the kernel.

In the case of the solaris operating system, you can read the actual value with:

ndd /dev/tcp tcp_time_wait_interval

(value is in ms)

If you want to set the value to 1 minute, use:

ndd -set /dev/tcp tcp_time_wait_interval 60000

E.2 How must the Xprint Pot-Masters be rebooted ?

It is strongly advised against restarting all the Pot-Masters at the same time, in order to avoid saturation

about the Xprint DB management.

The mastership handling cannot be processed so quickly between each potential master .

So the servers must likely be booted with a delay corresponding on a startup completion time.

(Same advise can be given when you xpstart on different hosts of a domain)

E.3 Why do I get the error message XP000158 : Database installation

error?

This is because there is no entry for the spooler in the services file. (/etc/services on Linux/Unix), usually

%WINDIR%/system32/drivers/etc/services on Windows. You must add the entry Xprint_db and chose a port

number of your choice.
