Required Connection

None

API Include File

sqlenv.h

C API Syntax

/* File: sqlenv.h */ /* API: Set Client */ /* ... */ SQL_API_RC SQL_API_FN sqlesetc ( struct sqle_conn_setting * pConnectionSettings, unsigned short NumSettings, struct sqlca * pSqlca); /* ... */

Generic API Syntax

/* File: sqlenv.h */ /* API: Set Client */ /* ... */ SQL_API_RC SQL_API_FN sqlgsetc ( struct sqle_conn_setting * pConnectionSettings, unsigned short NumSettings, struct sqlca * pSqlca); /* ... */

API Parameters

pConnectionSettings

Input. A pointer to the sqle_conn_setting structure, which specifies connection setting types and values. Allocate an array of NumSettings sqle_conn_setting structures. Set the type field of each element in this array to indicate the connection option to set. Set the value field to the desired value for the option. For more information about this structure, see SQLE-CONN-SETTING.

NumSettings

Input. Any integer (from 0 to 5) representing the number of connection options to set.

pSqlca

Output. A pointer to the sqlca structure. For more information about this structure, see SQLCA.

REXX API Syntax

SET CLIENT USING :values

REXX API Parameters

values

A compound REXX host variable containing the connection settings for the application process. In the following, XXX represents the host variable name.

XXX.0

Number of connection settings to be established

XXX.1

Specifies how to set up the CONNECTION type. The valid values are:

1

Type 1 CONNECT

2

Type 2 CONNECT

XXX.2

Specifies how to set up the SQLRULES. The valid values are:

DB2

Process type 2 CONNECT according to the DB2 rules

STD

Process type 2 CONNECT according to the Standard rules

XXX.3

Specifies how to set up the scope of disconnection to databases at commit. The valid values are:

EXPLICIT

Disconnect only those marked by the SQL RELEASE statement

CONDITIONAL

Disconnect only those that have no open WITH HOLD cursors

AUTOMATIC

Disconnect all connections

XXX.4

Specifies how to set up the coordination among multiple database connections during commits or rollbacks. The valid values are:

TWOPHASE

Use Transaction Manager (TM) to coordinate two-phase commits

ONEPHASE

Use one-phase commit

NONE

Do not enforce single updater and multiple reader

XXX.5

Specifies the maximum number of concurrent connections for a NETBIOS adapter.

XXX.6

Specifies when to execute the PREPARE statement. The valid values are:

NO

The PREPARE statement will be executed at the time it is issued

YES

The PREPARE statement will not be executed until the corresponding OPEN, DESCRIBE, or EXECUTE statement is issued. However, the PREPARE INTO statement is not deferred

ALL

Same as YES, except that the PREPARE INTO statement is also deferred

Sample Programs

C

FORTRAN

\sqllib\samples\fortran\client.f

REXX

\sqllib\samples\rexx\client.cmd

Usage Notes

If this API is successful, the connections in the subsequent units of work will use the connection settings specified. If this API is unsuccessful, the connection settings are unchanged.

The connection settings for the application can only be changed when there are no existing connections (for example, before any connection is established, or after RELEASE ALL and COMMIT).

Once the SET CLIENT API has executed successfully, the connection settings are fixed and can only be changed by again executing the SET CLIENT API. All corresponding precompiled options of the application modules will be overridden.

For information about distributed unit of work (DUOW), see the Administration Guide.
