Hi,
Today, I was trying to have a DSORG=PS DASD dataset (output from
ADRDSSU DUMP) with Extended Format, it failed with IEC143I 213-B8, where
B8 means "An OPEN was attempted against an extended-format data set with
a DCB that specified EXCP. EXCP is not supported for extended-format data
sets" according to manul.
Finally, I specified DSNTYPE=LARGE instead to overcome the 65535 tracks per
volume limit.
However, I don't know that output file (DSORG=PS) from ADRDSSU is using
EXCP access method and how do I know if a DASD dataset was proccessed by
EXCP instead of QSAM access method??
Is that the DCB=(DSORG=PS,LRECL=0,RECFM=U,BLKSIZE=27998) means the
dataset was processed by EXCP access method??
Can anyone give me a hint? Thanks....
Technically, you can never really be sure if EXCP was used for a
supported data set. The "gentleman's agreement" used by z/OS
applications is the specification of MACRF=E on the DCB at OPEN time.
For EF data sets, that triggers the abend you are seeing.
