EATTR parameter
Connect:Direct® for z/OS® support for EAV includes support for the EATTR data set attribute.
EATTR has two valid values:
- OPT - (optional) the data set can have extended attributes. If it is allocated on an EAV, it is biased towards being allocated in CMS.
- NO – the data set cannot have extended attributes. If it is allocated on an EAV, it is allocated in TMS.
In IBM Connect:Direct for z/OS,
the EATTR value can come from a number of places. When it is specified
in more than one place, this order of precedence is used:
- EATTR (in COPY statement) or SYSOPTS EATTR.
- TYPE when the TYPE record contains an EATTR.
- LIKE or SYSOPTS LIKE (dataset attribute).
- DATACLAS or SYSOPTS DATACLAS.
- TYPE when the TYPE record contains a DATACLAS.
- The COPY FROM dataset's EATTR setting (propagation).
- Otherwise, if an EATTR value is not specified when a data set is created, the system uses a default behavior equivalent to OPT for VSAM, and NO for non-VSAM.
