DFS3439W I/O ERROR READING THE DIRECTORY FOR ddname {-nnn}
Explanation
An I/O error occurred while reading the data set,
indicated by ddname, during processing of one of
the following commands:
- /MODIFY PREPARE
- INITIATE OLC PHASE(PREPARE)
- /MODIFY COMMIT
- INITIATE OLC PHASE(COMMIT)
If the error occurred on a FORMAT library that has concatenated data sets, nnn indicates on which of the concatenated data sets the error was received.
System action
The command is ignored.
Programmer response
If the I/O error occurred on a data set currently in use by the online IMS system, that system might shortly encounter a similar condition. If the error occurred for an inactive data set, you should recreate that data set.
