DSNB207I DYNAMIC ALLOCATION OF DATA SET FAILED. REASON = rrrr DSNAME = dsn

Explanation

A required data set of a Db2 table or index space could not be allocated. Reason code rrrr, which is returned by dynamic allocation, indicates the reason for the failure. Refer to the appropriate version of the MVS Authorized Assembler Services Guide (SA22-7608) publication for a description of this reason code. The dsn indicates the data set's DSNAME.

After being issued for a given data set, this message is disabled for that data set.
