Siemens V4.0 Optimizing performance with Spool, Setting the priority for print jobs from Spool

Configuring Advanced Server for UNIX Configuring printers on the UNIX system

Setting the priority for print jobs from SPOOL V4.x

The priority for print jobs from SPOOL V4.x cannot be modified with the net print <queue> /priority:<number> command.

●To set the priority, use the net print <queue> /parms:"... -pr <number> ..." command. If nothing is set, Advanced Server for UNIX prints with the priority for root (default 1).

5.5.3Optimizing performance with Spool V4.x

In large SPOOL network configurations with many objects, performance problems can arise in connection with Advanced Server for UNIX. When printing, the lmx.srv server process assigned to the PC can accept more jobs in parallel. When querying status infor- mation, e.g.with net print, the lmx.srv server process allocated to this command works exclu- sively for this job, and other PCs are prevented from accessing files and from printing for several seconds.

In order to restrict delays in working with SPOOL V4.x on only one PC with Advanced Server for UNIX V4.0, you can change the configuration of Advanced Server for UNIX in such a way that each PC receives its own server process. This is an acceptable solution in particular for smaller configurations.

To do this, change the settings in the “Process Parameters Entries“ of the Registry of the Advanced Server for UNIX for the keys MaxVCPerProc and MinVCPerProc to “1” .

In order to obtain a separate process for each PC, stop and start the server with the commands:

This solution generates a large number of processes. If this causes problems, please contact your Support Center for optimum partitioning.

5.5.3.1Large SPOOL V4.x configurations

In large SPOOL V4.x configurations with a large number of printers and printer groups and a large number of jobs in the queues, timeout problems may occur on the clients. For example, the Windows Print Manager only waits a certain length of time for the answer from the server; after this time has elapsed an error is returned.

To avoid problem like these, there is a parameter in the “Parameters Entries Section” of the Registry: “CallXpstatDev” . This parameter controls wheather the device status of Spool V4.x is queried or not. The default is set to “not query the device status” .

Prevent the number of print jobs in the printer queue from increasing. This problem is caused by stopping the queue or by long term printer problems.
