IST1288I
TOPOLOGY DATASET RETRIEVAL WAS NOT SUCCESSFUL, CODE = code

Explanation

VTAM® issues this message when topology data from a previously saved data set could not be read successfully.

This message is issued primarily for information and does not indicate a loss of processing ability. If you see this message every time you start VTAM, this indicates that it will take longer to set up your first few sessions.

code indicates the reason for the error and is one of following:
Code
Error
1
Insufficient storage.
2
The disk file is undefined.
4
Disk I/O errors occurred. These errors are reported in separate messages issued prior to this message.
8
The data set recovery task abended. This message is issued with no further attempt at data set recovery.
9
The previously saved data set was incomplete.
10
The topology and routing services task abended while attempting to recover topology from the database.
11
The topology and routing services data set was found, but the data set will be ignored because there is a name conflict.
12
The topology and routing services data set will be ignored because the data set was saved in a format that is not supported by VTAM.

System action

Processing continues.

Operator response

Code(s)
Error
1
Issue the DISPLAY STORUSE command to display storage usage for storage pools. Message IST981I displays total VTAM private storage information. If this message does not appear in the display, you may need to reissue the DISPLAY STORUSE command, specifying a higher value for the NUM operand. See the z/OS Communications Server: SNA Operation for additional information.

Save the system log and request a dump for problem determination.

2, 9, 11, 12
Save the system log for problem determination.
4, 8, 10
Save the system log and request a dump for problem determination.

System programmer response

Increase storage as required.

See the z/OS Communications Server: SNA Operation and the z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures for additional information.

See the z/OS Communications Server: SNA Diagnosis Vol 2, FFST Dumps and the VIT for information about analyzing dumps and about analyzing storage using the VIT analysis tool, if external trace is active.

2
You must define the missing disk file TRSDB. See the applicable sequential access method documentation and the z/OS Communications Server: New Function Summary for additional information.
4
See the applicable sequential access method documentation for more information.
8
See the applicable sequential access method documentation for more information.
9
This code indicates that no action was taken to correct an earlier problem identified in message IST1122I during a previous VTAM checkpoint. You may want to check the system log for the last time you issued the MODIFY CHKPT command to review the information in message IST1122I.
10
Review the contents of the system dump to determine the correct problem determination action.
11
This code indicates that the data set cannot be used because it was saved under a different control point name. VTAM will not read the data set, but will write to it. The next time a MODIFY CHKPT command is entered, the old data set will be replaced with the new one.
12
This code indicates that the data set cannot be used because it was saved in a format that is not supported by VTAM. The next time a MODIFY CHKPT command is entered, the data set will be reformatted and can be used.
