Types of FAVER2 Exported Files Supported

VSAM

All VSE VSAM files types (KSDS, ESDS, RRDS, VRDS) are reloaded into their appropriate z/OS counterparts.

SAM managed

This variation of VSE VSAM is reloaded as an ordinary sequential data set in MVS. Fixed, fixed blocked, variable, and variable blocked record formats are supported. Variable records will have RDWs built for them and appended as the record prefix and variable blocks will have BDWs prefixing the blocks to make them conform to MVS data set standards. Correct processing of SAM managed data depends on the RECORDFORMAT set by IDCAMS in the VSE system. If this value is not set, CA-FAVER2 will record this as RECFM=U, and CA-FAVER will reload them as RECFM=U data sets.

SD

Ordinary sequential disk data sets will be reloaded, but may not have the correct file attributes. The record format, the logical record length and the block size may not have been available to CA-FAVER2 at export time. If CA-FAVER2 can acquire this information at export time, it will be recorded on the export tape and will be used by CA-FAVER during the restore process. When the file attributes are not available, the file will be processed as undefined record format using 32760 as the both the logical record length and the block size. The net result is the actual data blocks will be restored to disk as they originally appeared in the VSE system from which they came, but the MVS disk label (Format 1 DSCB) will reflect RECFM=U BLKSIZE=32760 LRECL=32760. To access these files correctly, you will need to code the correct values with DCB=(LRECL=x,BLKSIZE=y,RECFM=z) in the JCL for your application. A GV912 informational message will indicate the largest and smallest record size and block size encountered to assist you in determining the correct values to use.

In addition, optional parameter SECALLOC is available to provide secondary allocation values for restoring sequential datasets exported using CA-FAVER2.

Note: For more information, see RESTORE Statement.

Note: Non-CI format data sets are not supported. If one is encountered, it is noted with a GV911 message. Also, these files are identified in the GVMAP reports for your convenience.
