Issue/Introduction

Getting this TSO message when performing file transfer. Transfer gets performed correctly, but returning into clist to perform any command, this messsage appears:

IKJ56247I FILE SYS00488 NOT UNALLOCATED, IS NOT ALLOCATED

XCOMCNFG NOT FOUND.  REQUIRED DDNAME SYS00488 IS NOT ALLOCATED.

Attached is a DODEBUG trace

Environment

Release : 12.0

Component : CA XCOM Data Transport for z/OS

Resolution

Client found the problem. The name of the clist dataset being used to call XCOM is named 'HLQ.CBXGCLS0', it is also the dataset being used for the transfer to the XCOM partner. Your clist does perform a FREE of this dataset,which is normal, being the input dataset for this transfer. The problem does not surface if a dataset other CBXGCLS0 is being used.

Additional Information

The IKJ56584I message means that CLIST (or command) XCOMCNFG was not found because something has freed the CBXGCLS0 library which was allocated under the DDNAME SYS00488 by ISPF.  The ALTLIB command allocates this library dynamically, but somehow it is getting freed.
