Error Message: Dynamic PSB error.

Products

• File Master Plus for IMS

Issue/Introduction

CAWL549E '** Dynamic PSB Error **' .TYPE=W 
'An error was encountered allocating the dynamic PSBLIB ' + 
'temporary PDS. ' 

At first it was thought to be a security issue, but all users have the same security.
All we are doing is browsing a database,
This happens in either BMP or DLI mode.

 

Environment

Z/OS 

Cause

The normal behavior, is the product can allocate up to 10 dynamic PSB libraries. The format of the Data set name is

[ZPREFIX.]ZUSER.CAWKEB#n.ASYSID.PSBLIB

  The data set name for a given user may vary depending on
- The user's PREFIX setting of his ISPF session
- The System user is executing in.
- n is a value in the range 0-9

When one of these PSB libraries exist the product increments n in order to generate the next Library name. 

These temporary datasets are deleted at the end of a successful execution of Browse or Edit. However, if some sort of error occurs during Browse or Print, the cleanup of these datasets may not get done. 

 

Resolution

f there are already 10 of these libraries (n=0 through 9) out there, then we put up a screen that lets you delete 1 or more of these datasets so a new one can be created.

If you fail to delete one of these datasets, that is when the CAWL549E error message is issued:

CAWL549E '** Dynamic PSB Error **' .TYPE=W
'An error was encountered allocating the dynamic PSBLIB ' +
'temporary PDS. '

 

The dataset names should be unique for each user.
