SORTIN

The SORTIN keyword is valid with the Prefix Resolution/Update function.

You can specify this option in a Prefix Resolution/Update function global options module or in PLUSIN. The following table describes the keyword.

Table 1. Create IMS format records keyword

To do this

Specify this in PLUSIN

Create IMS format records and read the IMS format work file on SORTIN.

SORTIN(Y)

Create BMC format records and read the BMC format work file on SORTIN.

SORTIN(N)

Internal Default: (N)

The Prefix Resolution/Update function assumes that IMS format work file records will be used as input to PRPURG10, PRPURG20, and PRPURG40 using the DFSURWF1 DD statement, and that BMC format work file records will be used as input to these phases using the SORTIN DD statement. If you create only IMS format records and want to read the IMS format work file records on SORTIN, specify SORTIN(Y).

Specifying SORTIN(Y) will not improve performance because the IMS format work file records must still be read using an input exit routine. The SORTIN option is provided for full compatibility with existing JCL. For best performance, create BMC format records during database load processing and use them throughout the reorganization process.
