Hi all,

When i run my cobol program it abends with U1473.

My cobol program calls another module which accesses IDMS.
The error code is,

Quote:
CEE3250C The system or user abend U1473 R=NULL was issued.


As far as i referred, I got to know that this is because of 'MAXERUS'.
The MAXERUS limit is reached.

What is the solution for this problem?

Correct me If I am wrong.

Hi,

Reason for the 1473 Error code:

A new run unit would exceed the MAXERUS (maximum external run-units) value, as specified in the SYSGEN.

The following possible causes, you can do.

1. This means the system is very busy now (or having sever problems like example given in third point ) and you should be able to just re-run the job again in a few minutes.

2. Or you can get the help from DBA

i.e. The DBA’s may need to change MAXERUS (maximum
external run units) in the SYSGEN.

3. Other than an abnormally busy system, here is an example that can cause the system to be “busy”. You have a batch job
running in protected update. Online transactions are trying to access the same area, so they go into a WAIT state (up to the number of seconds specified in the external wait time). So instead of finishing in 1 or 2 seconds, the stay in a WAIT state for 1 to 20 minutes. New transactions come in, and they try to access the area, and go into a wait state. So in a matter of minutes, you have 70 online tasks all active - but in a WAIT
state. If your MAXERUS is set to 70 - you have reached it - and all new income transactions will ABEND with a 1473.
