RO_CURSOR

This directive determines what type of database cursor your COBOL read-only cursors use.

Syntax:

RO_CURSOR={SCROLL | FORWARD | DYNAMIC | KEYSET | STATIC | FF | IC_FH}

FF	Fast Forward
IC_FH	Independent Connection Fire Hose

Used at compile time:	No
Behavior at run time:	Source file

See Scope - OpenESQL SQL Compiler Directive Options for more information.

SCROLL, FORWARD, DYNAMIC, and KEYSET are standard ODBC types.
FF and IC_FH are cursors specific to MS SQL Server.
Under MS SQL Server, prefetching does not work with FORWARD and IC_FH.
As its name indicates, an IC_FH cursor has its own independent connection to MS SQL Server. Because of this, these cursors are sensitive to the isolation level and locking protocol of previous data access in the application program.
When using a SQL Server connection that supports MARS, MARS is automatically enabled and IC_FH is converted to FORWARD.
