Can not start spooler

[Shen Yang]

Hello,

I can not start up spooler. I checked the /var/spool/lp folder, there are no FIFO and SCHED files. When I check the /var/spool/lp/log file, I saw following messge:

FIFO: Printers --

Any ideas what is happening here.

Thanks.

In order for the scheduler program (lpsched) to run, two files cannot
exist on the system. They are the SCHEDLOCK and tmplock files (both
in the /usr/spool/lp directory).

The SCHEDLOCK file is documented in the HP-UX System Administration
Tasks manual (HP Part Number 98594-900061), Chapter 7, or the HP
9000 Series 800 HP-UX System Adminstration Tasks Manual, Volume I
(HP Part Number 92453-90038), Chapter 7. However, the tmplock
file is not mentioned in any HP-UX version 7.0 manuals.

The tmplock file is used in an algorithm which creates the SCHEDLOCK
file. On rare occasions, if the lpsched program is killed within a
small window, this file will be left on the system. Then, if this
file is not removed, the lpsched program will not run.

I checked both /usr/spool/lp and /var/spool/lp folders, there are no SCHEDLOCK and tmplock files on either of them.

Check the mode on the file /var/spool/lp/outputq, it should be 644.

This error message could also be generated if the system has the maximum number of files open that are allowed at any one time.

Hace you tried sam?

# sam

Printers & Plotters
LP Spooler

Save Spooler Configuration

Restore Spooler Configuration

sam will try to recover any errors.

Also double check all the necessary permission/ownership of your spooler directory and executables .. for example:

-r-sr-xr-x root bin /usr/sbin/lpsched

drwxr-xr-x lp bin /var/spool/lp
