DWW0621I
An I⁄O error occurred after a get request to the aaaa data set. The RBA⁄RRN=bbbbbbbb. VSAM return codes are R15=cc, FDBK=dd.

Explanation

An attempt to get a record from data set aaaa failed because of an I⁄O error. bbbbbbbb is the relative byte address (if an entry-sequenced data set (ESDS)), or the relative record number (if an relative record data set (RRDS) or variable relative record data set (VRRDS)) of the record to be processed when the I⁄O error occurred. cc is the return code in register 15, and dd is the value of the feedback field in the request parameter list (RPL).

System action

Some VSAM errors might be followed by another message in the range DWW0210–DWW0212. These messages show the system action and indicate that CICS® VR will terminate.

Other VSAM errors will not be followed by another message because they are acceptable for:
  • The backup-while-open facility, where the updates are in progress while the backup is being made.
  • VSAM data sets updated on pre-CICS/ESA 4.1 systems, where the after-image is written to the log before being applied to the VSAM data set.
  • Data set updates that were logged but not yet applied to the VSAM data set
For an explanation of the codes in this message, see z/OS DFSMS Macro Instructions for Data Sets .

Also see CICS VR Implementation Guide and Reference for more information about acceptable VSAM errors.

User response

None.
