Basis Ticket :

We have the ECC 5.0 installed on the HP UX. Whenever I am trying to run the t-code ST06 for the application server of the production, I am getting one message "SAPOSCOL is busy, try again". I am able to get the run the ST06 for other application servers. 
The current version what we have for Saposcol is : Version: COLL 20.87 640 - hpxOscol 07/2003.
It will be a great favour if anybody can provide me the steps from the scrach in how to run the SAPOSCOL.

1) login as <sid>adm

2) check if your saposcol is running at unix level
ps -ef | grep saposcol

3) go to /sapmnt/NPD/exe

Check if saposcol file is existing
Check the owner and the permission of the file

To start SAPOSCOL with the command saposcol (or saposcol -l). 

Saposcol can run independent of the SAP system, so you can try to start it individually using:

Try to start saposcol with command saposcol -l
You can know status of the saposcol by saposcol -s and stop it by saposcol -k

---

Try to check, if you have cleaned up Share memory present in /usr/sap/tmp/dev_coll & try to get latest patch of SAPOSCOL.

Shared memory cleanup can be done as follows:

1) Login with the user <sid>adm and perform these steps
saposcol -d
Collector > clean
Collector > quit
saposcol -k to stop the collector.
Before restarting
saposcol -d
Collector > leave (You should get a message Shared memory deleted)
Collector > quit
cd /usr/sap/tmp
mv coll.put coll.put.sav
cd
saposcol

"coll.put" ,if this file contains the old shared memory and should be deleted in order to get a clean start. Please look at the SAP Note 548699 and follow point 7 very carefully:

If you are unsuccessful in clearing shared memory, please try the following commands to clear the shared memory:

2)
$ saposcol -kc
$ saposcol -f
If this doesn't work, then try:

3)
cleanipc 99 remove on the O/S level (Check note #548699 first)

4) If not you have to do a OS level restart to fix the issue.

Also check if new saposcol can be applied as per Note 19227
