Issue/Introduction

 

Issue:

We are getting u901 abends in the Telon Design Facility(TDF). We ran verify's against the Telon permanent VSAM files, and they all showed no bad blocks for the TDF VSAM files.

We tried to do an unload of the TDF and also received a u901.

 

 

Environment: 

 Telon 5.1

 

Cause:

Editting the Telon Design Facility with multiple versions/releases of Telon, corrupted the TDF. First the TDF was brought up with Telon 5.1 libraries, and then the next day, the TDF was brought up with Telon 4.1 libraries. Telon is not backward compatible. 
 

 

Resolution:

The best resolution for this U901, is to restore the Telon VSAM files(permanent files).

Backups should be taken depending on the amount of activity within the Telon Design Facility.

Daily, 2-5 times a week, or weekly. 

 

Additional Information:
