The system no longer collects record type 68 as of January, 2000
Note that because VSAM catalogs are no longer supported and no longer exist, the system does not collect record type 68. However if you are using downlevel versions of SMF files, these explanations may still be useful.
Record type 68 is written when an entry (a component, cluster, catalog, alternate index, path, or non-VSAM data set) in a VSAM catalog is renamed using the ALTER access method services command. This record identifies the VSAM catalog in which the object is defined, and gives the old and new names for the object. It identifies the job log identification and user identification. The job name, time, and date that the reader recognized the JOB card (for this job) constitute the job log identification.
If a system task caused the record to be written, the job-name and user-identification fields contain blanks and the time and date fields contain zeros.
