HISTORY

Specifies the type of history record to be written.

NONE: Specifies that a history record is not written.
ODBC: Specifies that an ODBC history record is written.
VSAM: Specifies that a VSAM history record is written. This option is fault tolerant in that a missing or invalid XCOMHIST data set is ignored. The server starts, but no VSAM history records are written.
VSAMREQ: Specifies that a VSAM history record is written. This option also REQUIRES that a valid XCOMHIST data set be available for use by the server. If an XCOMHIST data set which has the required attributes (as an example, correct RECSIZE and KSDS organization) is not available, the server will not start.

Default: VSAM
