scheduler is not running

[Yilak Yehualashet]

I run lpsched and checked the status by running lpstat -t. And it reported scheduler is not running.

Pls advice!!

Hi,

if the scheduler won't start up when you execute lpsched command, check to see if the SCHEDLOCK file exists in the /var/spool/lp directory. If it exists , remove it and try again to start it.

to check if it has been started type:

ps -ef| grep sched

A shorter check if scheduler runs:

lpstat -r

[Yilak Yehualashet]

Tks

There is no SCHEDLOCK in /var/spool/lp and also when i
ps -ef|grep sched
The response
root 20 0 0 07:34:06 ? 0:00 supsched

and the problem is still.

When i run lpsched the immediate response is
scheduler is running

But when i check it with lpstat -t the response is as before scheduler is not running

[federico_3]

and FIFO file under the same directory?
It there is remove it and try to restart the scheduler

Check also the file /var/spool/lp/log to see if there are any problems!

Hi,

start with: lpsched -v
and then look in /var/adm/lp/log for messages of lpsched.

There isn't any FIFO

and for lpsched -v. the log is

lpsched: can't open output queue file
FIFO: Destinations --
FIFO: iss_sup: p not enabled not busy /dev/null
FIFO: Printers --
FIFO: iss_sup pid and id unknown
FIFO: Classes --

Hi,

check permission/user of /var/spool/lp
should be:
drwxr-xr-x 4 lp bin 1024 Oct 31 08:17

Regards

[Yilak Yehualashet]

HI

The permission is as you mentioned

[federico_3]

Have you tried to define a new printer? if yes, remove all the files connected to it ( find / -name "name printer" ) because there could be somthing that blocks the scheduler.

Hi,

do an lpshut and then look with ps -fulp to see if there are any lp processes left. If yes kill them (kill or kill -9 )

Regards

[Yilak Yehualashet]

Hi there

I removed all printer names from all directories found. Still the problem persists.

I trie also lpshut . The imediate response is scheduler not running. and ps -fulp results no lp process.

Hi,

Here's some things to check (done on an 11.00 system):

1) mode and ownership of outputq file
# ll /var/spool/lp/outputq
-rw-r--r-- 1 lp sys 4183200 Sep 29 16:35 /var/spool/lp/outputq
(if outputq doesn't exist, create it, making sure that mode and ownership are correct)

2) mode and ownership of lpsched
# ll /usr/sbin/lpsched
-r-sr-xr-x 1 root bin 57344 Aug 9 1999 /usr/sbin/lpsched

(If you need to change the mode, it's:
chmod 4555 /usr/sbin/lpsched)

3) Once again, permissions of everything down to /var/spool/lp:

# ll -d /
drwxr-xr-x 31 root root 2048 Oct 30 13:54 /
# ll -d /var
dr-xr-xr-x 20 bin bin 1024 Oct 3 13:04 /var
# ll -d /var/spool
drwxr-xr-x 14 root sys 1024 Oct 13 10:11 /var/spool
# ll -d /var/spool/lp
drwxr-xr-x 4 lp bin 1024 Oct 27 07:49 /var/spool/lp

I hope this helps,
Bruce

Thank you all and specially Bruce Laughlin . It was the permission of the outputq.

How could i remove the queues which i removed from all directories. They keep coming on the lpstat -t result.

Thanks

[Andreas Voss]

Hi,

for all queues do:
cancel -e

Hi

I wanted to remove the printer name gss01 , gss and iss_sup.

But it keeps on saying they are non-existant.
they appear on lpstat -t as follows

scheduler is running
no system default destination
device for iss_sup: /dev/null
gss01 accepting requests since Oct 27 10:31
gss accepting requests since Oct 27 10:42
iss_sup accepting requests since Oct 31 07:54
iss_sup not accepting requests since Oct 31 18:13 -

printer gss01 is idle. enabled since Oct 30 18:10
fence priority : 0
printer gss is idle. enabled since Oct 27 10:42

printer iss_sup is idle. enabled since Oct 31 07:54
fence priority : 0
printer iss_sup disabled since Oct 31 18:13 -
new printer

[Andreas Voss]

Hi,

to remove do this:
lpshut
lpadmin -xgss01
lpadmin -xgss
lpadmin -xiss_sup
lpsched

Regards

[Yilak Yehualashet]

Hi

I have done that. For your info here is what i did

/var/spool/lp lpadmin -xgss
lpadmin: destination "gss" non-existent
root@imisaa1:/var/spool/lp lpadmin -xgss01
lpadmin: destination "gss01" non-existent
root@imisaa1:/var/spool/lp lpadmin -xiss_sup
root@imisaa1:/var/spool/lp lpadmin -xiss_sup
lpadmin: destination "iss_sup" non-existent
root@imisaa1:/var/spool/lp lpsched
scheduler is running

root@imisaa1:/var/spool/lp lpstat -t
scheduler is running
no system default destination
gss01 accepting requests since Oct 27 10:31
gss accepting requests since Oct 27 10:42
printer gss01 is idle. enabled since Oct 30 18:10
fence priority : 0
printer gss is idle. enabled since Oct 27 10:42
fence priority : 0
lpstat: execlp failed
no entries

[Andreas Voss]

Hi,
when you want to remove ALL queues you could do:
lpshut
cd /var/spool/lp
mkdir old # just for save
mv pstatus qstatus outputq old
lpsched

Now every lp information is lost and you can start from scratch.

Thank you Andreas !!

You have been of great help
