Issue/Introduction

CA Datacom dynamic extend fails with a SE37-08 abend due to insufficient space on the volume.

The following errors can be seen in the dynamic extend: 

DB01705I - DYNAMIC EXTEND START IXX999 TRK 1,487,550 PRD.IXX999

ERROR DESCRIPTION: IEC032I                                                
A multi-volume physical sequential data set was being written on DASD.    
Space on next volume is needed. Either no space, or data set already      
existed, or no space on the VTOC or VTOC index. See manual for more        
detail.                                                                    
END ERROR DESCRIPTION: IEC032I                                            
DB01702I - DYNAMIC EXTEND OF AREA IXX999   HAS FAILED  

The file may still be usable by the MUF but will issue the following message:

IEC145I 413-1C,IFG0193A,DCOMPRD,DCOM,IXX999,1C60,DCI000,  760
PRDB.IXX092
ERROR DESCRIPTION: IEC145I
An OPEN macro instruction was issued for a data set, but volume
sequence number on the associated DD statement was greater than the
number of volumes containing the data set.
END ERROR DESCRIPTION: IEC145I

Any further attempt to EXTEND the file again will corrupt the file further and make it unusable.

A second EXTEND will receive message DB01405I - DATA SET VOLUME IGNORED, NOT CHAINED and incorrectly calculate the number of tracks on the file.

After this any attempt to use the file will fail with return codes 13 (05) or 94 (86).

 

Cause

This is caused by a z/OS problem with managing the VTOC. The error occurs during IBM EOV processing. When an ABEND E37-08 occurs the DS1IND80 bit (last volume indicator) is being turned off in the DSCB on the last volume in the VTOC. This causes the DEBEOF flag (X'20'– end of file (EOF) encountered ) not to be set in the DEB. 

 

Environment

Release : 15.1

Component : CA DATACOM/DB

Resolution

To resolve the problem you will need to restore the file from a backup.

This can be done using z/OS system utilities if it was backed up that way.

Otherwise use Datacom utilities:

  • Rename existing file
  • Reallocate a new file
  • Run a DBUTLTY INIT
  • Run a DBUTLTY LOAD using a Datacom BACKUP as input

Currently, there is no IBM PTF to fix the problem.

IBM FIN APAR OA60902 has been created for this problem and will be fixed in the next product release of DFP End-Of-Volume code.
