Troubleshooting

This chapter describes some of the common problems that might be

encountered in Advanced Printing Software and describes what steps can be

taken to correct the problems.

12.1 Solving Server Problems

This section contains descriptions of server errors that can occur during

normal print system operation. Note that these errors are characterized as

server errors, but this does not necessarily mean that they are errors that

are caused only by spooler or supervisor objects; they can be caused by other

problems on the server host or the network environment..

12.1.1 Determining Which Server Processes Are Running

If a supervisor or spooler process is not responding to client requests, you can

use the following command to determine which server processes are running:

# ps -ef | grep pdsp

If you do not see process entries for pdsplr, pdspvr,orpdspvlpr, make

sure that you are looking at the correct host.

To restart the missing server process, use one of the following commands:

# /usr/pd/lib/pdsplr

# /usr/pd/lib/pdspvr

# /usr/pd/lib/pdspvlpr

If the supervisor or spooler process is running but not responding to client

requests, you can use the pdls command to determine the state of the object:

# pdls -c server -r all -s line server_name

If there is no response from the server, determine if the protoserver daemon

is running:

# rpcinfo -u host 105004

If the protoserver is running, the following is displayed:

# program 105004 version 1.2B ready and waiting
