The behaviour of these functions is affected by settings in php.ini.
|ibm_db2.i5_allow_commit||"0"||PHP_INI_SYSTEM||Available since ibm_db2 1.4.9.|
|ibm_db2.i5_dbcs_alloc||"0"||PHP_INI_SYSTEM||Available since ibm_db2 1.5.0.|
|ibm_db2.instance_name||NULL||PHP_INI_SYSTEM||Available since ibm_db2 1.0.2.|
|ibm_db2.i5_all_pconnect||"0"||PHP_INI_SYSTEM||Available since ibm_db2 1.6.5.|
Here's a short explanation of the configuration directives.
This option controls the mode used for converting to and from binary data in the PHP application.
This option controls the commit mode used for i5 schema collections in the PHP application.
0 no commit (see i5_commit for override)
1 allow commit (see i5_commit for override)
This option controls the internal ibm_db2 allocation scheme for large DBCS column buffers.
0 no expanded allocations (see i5_dbcs_alloc for override)
1 use expanded allocations (see i5_dbcs_alloc for override)
On Linux and UNIX operating systems, this option defines the name of the instance to use for cataloged database connections. If this option is set, its value overrides the DB2INSTANCE environment variable setting.
This option is ignored on Windows operating systems.
This option overrides i5 db2_connect full open and close in the PHP application. When ibm_db2.i5_all_pconnect = 1, all db2 connections become persistent (db2_pconnect). On i5/OS, db2_pconnect performs dramatically better with lower machine stress over db2_connect. This is a convenience override of db2_connect to evoke db2_pconnect without PHP source code changes.
0 db2_connect default full open and close
1 db2_connect override to db2_pconnect for persistent connection only
