 Posted: Wed Nov 10, 2004 8:17 am Post subject: U0456 ABEND - How can we resolve it? |
 |
|
Hi Board,
Today while running the IMS Database uploading jobs I got an abend. Hence we restarted the job from the last check point onwards. But it has got abended with U0456 error. I saw the explanaction of the abend code.
It is given like that "The PSB locked due to previous error/Prior execution of the program". I understand that previous execution caused to get U0456 abend.
Now I want to see the PSB status whether it is locked (or) not?
If it is not locked how can we restart this PSB?
I tried with the command "/DIS PROGRAM PSBNAME". But I didn't get any information.
And also I know that batch JOB will run in MVS for each and every sub-system when it is up. So for each IMS region there will be a batch job will run. Hence I saw in the SDSF also whether I can find out (or) not. But I didn't find it(May be I don't know how to find).
Please anyone can help how to resolve this problem.
I am getting confusion of "Restarting the PSB", "Restarting the Region" and "Restarting the Database". Please anyone can give me the clear clarification.

Ramu_mohan21,
You need to log on to IMS region, just like you like logon to CICS. once you are logged on then you can issue the
| Code: |
/DIS PROGRAM PSBNAME
|
now it displays the psbname status. If it is locked and stopped then you can start the psb
| Code: |
/START PROGRAM PSBNAME
|

You need to know the high level qualifier of your IMS system job. But as an application programmer you don't have to worry about these jobs, unless your IMS region is down.
As an application programmer you will never have the restart the region or database. It is your IMS admin who does that.
All you will doing is restarting your own PSB.
Hope this helps...
Cheers

Restarting the PSB: You are restarting your PSB(program). This may be due to many reasons. One reason is your case.
Restarting the Region: You are restartng the Region
No idea how to restart the region. Might be the same way...
Restarting the Datbase: You are restarting the Database. You can restart the DB as similar to PSB restart. Instead of PSB you need to give Database.
This is how you check the database is up or stopped.
/DIS DB database-name
/STA DB database-name(to restart).
Hope it helps....
Cheers,
Nippu. |

IMS BMPs run as dependant (subordinate) regions from the IMS control region. To restart the region means that you would be re-starting IMS.
IMS MPP (Online) dependant regions are run either as jobs or as tasks. If they run as jobs, they can be started for an IMS online session using the command /STA REG region-name. If they are run as tasks, then they are started from the OS console (or SDSF if you have the authority).
The START and STOP commands can be restricted by IMS security which is what appears to be happening in your case.
In our shop, only the operators or DBAs can issue these commands in the production environment. |
