ADAPREFETCH Statement

The ADAPREFETCH statement controls whether PowerExchange uses the Adabas prefetch feature to improve performance when reading records.

z/OS

Adabas

ADAPREFETCH={N|Y}

N
.
PowerExchange does not use the Adabas prefetch feature when reading records.

Y.
PowerExchange uses the Adabas prefetch feature when reading records to improve read performance.

Default is N.

On UNIX and Windows, Adabas does not allow prefetch processing with the ACBX interface. If you are using ACBX on one of these systems, and ADAPREFETCH=Y, PowerExchange reverts to ACB calls, which cannot read records larger than 32 KB. If you want to use ACBX on UNIX or Windows, do not specify the ADAPREFETCH=Y statement.
