Instructs OpenESQL to properly match your COBOL cursors with the database you are using, thus maximizing database cursor performance. BEHAVIOR makes use of multiple primitive directives and associates a default value for each primitive directive depending on the target DBMS. You can also override the default setting of any primitive directive.
Note:
- If you don't specify any BEHAVIOR primitive directives, and you also accept the default primitive directive values listed in the relevant table in the
Default Primitive Directives section later in this topic, the TARGETDB directive is not required; however, you must specify TARGETDB if you want to use different default values for any primitive directive.
- Setting the BEHAVIOR directive can also affect the SQL types returned when using Dynamic SQL. See the
DESCRIBE Statement topic for more information.
- Because the
JDBC API does not support prefetching, very limited support is provided for BEHAVIOR primitive directives with DBMAN=JDBC. See
DBMAN Directive Settings for more information.
Syntax:
BEHAVIOR={OPTIMIZED | UNOPTIMIZED | ANSI | MAINFRAME | CICS | JCL} [primitivedirective [value]]...
Parameters:
OPTIMIZED
|
Enables OpenESQL to optimize ambiguous cursor declarations; enhances the access speed
|
UNOPTIMIZED
|
Provides backward compatibility with earlier Micro Focus products, where ambiguous cursors are both updateable and scrollable
|
ANSI
|
Enables OpenESQL to work like the ANSI standard; enhances the access speed
|
MAINFRAME
|
Synonym for OPTIMIZED
|
CICS
|
Sets all of the following:
- Enables OpenESQL to work as it does on the mainframe, optimizing ambiguous cursor declarations
- Enhances the access speed
- Automatically sets the TRANSACTION primitive directive to GLOBAL
|
JCL
|
Sets all of the following:
- Enables OpenESQL to work as it does on the mainframe, optimizing ambiguous cursor declarations
- Enhances the access speed
- Checks for the following statements that are not compatible with JCL applications:
- CONNECT
- DISCONNECT
- SET CONNECT
- Reports an error for each incompatible statement found

See
Scope - OpenESQL SQL Compiler Directive Options for more information.
Default:
BEHAVIOR=OPTIMIZED
Comments:
- You can change the default setting to either ANSI or UNOPTIMIZED using the OpenESQL Configuration Utility. However, when the BEHAVIOR directive is specified in program code, project settings, or in a compiler directive file, the specified parameter overrides the default setting.
- Setting this directive can also affect the SQL types returned when using Dynamic SQL. See the
DESCRIBE Statement topic for more information.
- OpenESQL sets default values for primitive directives depending on the value of BEHAVIOR and your target database. See the topic
Primitive Directives for more information.

For more information on using BEHAVIOR to migrate your COBOL cursors, see the topic COBOL Program Migration Support.
You can fine tune the BEHAVIOR directive and override these default settings by providing alternate values for primitive directives. If you do this, you must set the TARGETDB directive.
