DFS3127I READ|WRITE ERROR OCCURRED ON THE RESTART DATA SET xxxxxx
Explanation
An error occurred while attempting to read or write the restart data set (RDS), or during or after an IMS checkpoint.
The variable xxxxxx has one of the following values:
- IMSRDS
- The error occurred on the data set defined by the IMSRDS DD statement.
- IMSRDS2
- The error occurred on the data set defined by the IMSRDS2 DD statement.
System action
If a read error occurred, IMS terminates the restart. If a write error occurred, IMS continues processing.
Operator response
Check the allocation of the restart data set. The RDS allocation needs to be large enough to contain at least 90 blocks reserved for RDS1 components BCPT, RRE, SIDX, and LCRE.
For a read error, delete and reallocate the RDS; then retry the restart by specifying FORMAT RS.
For a read
error in the Fast Database Recovery region, terminate the active IMS, scratch and reallocate the RDS,
and restart IMS by specifying FORMAT
RS. Then start the Fast Database Recovery region.
For
a persistent write error, terminate IMS,
scratch and reallocate the RDS, and restart IMS by specifying FORMAT RS.
For the appropriate recovery actions in an XRF environment, see IMS Version 15.2 System Administration.
