A macro (operation) was issued by VTAM® for the data space dataspace, and an error return code was returned without successful completion of the request.
where ccccc is in the range of 1–99999 and xxxxx is in the range of 0–FFFFC.
If the dataspace is ISTNMSDS or ISTNMPDS, and operation is DSPSERV CREATE or ALESERV ADD, only the LU0 interface is available for communication between VTAM and the NetView® program's session monitor.
If dataspace is ISTxxxxx or cccccIST, operation is DSPSERV CREATE, return_code is 08 and reason_code is 6B000911, there was a conflict with the dataspace name supplied by VTAM. Since VTAM tries four times to create a unique data space name, the occurrence of IST967I may only be informational. VTAM may have succeeded in creating the dataspace with another name. The DISPLAY STORUSE,DSPNAME=* can be used to confirm whether the ACB was opened with another name.
If operation is DSPSERV RELEASE, the data space interface will continue to function without releasing unused storage to virtual storage management.
Save the system log for problem determination.
See the z/OS MVS Programming: Authorized Assembler Services Reference ALE-DYN for a description of return_code and reason_code.
