Hier eine kurze Erklärung der Konfigurationsoptionen:

ibm_db2.binmode integer

This option controls the mode used for converting to and from binary data in the PHP application.

  • 1 (DB2_BINARY)

  • 2 (DB2_CONVERT)

  • 3 (DB2_PASSTHRU)

ibm_db2.i5_all_pconnect integer

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.

ibm_db2.i5_allow_commit integer

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)

ibm_db2.i5_dbcs_alloc integer

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)

ibm_db2.instance_name string

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.

ibm_db2.i5_ignore_userid integer

This option overrides i5 db2_(p)connect userid and password in the PHP application. When ibm_db2.i5_ignore_userid = 1, all db2 (p)connections become null userid and null password. Therefore Apache jobs connect with the current profile (NOBODY). Use of this override is only for simple DB2 based websites that never require profile switching and therefore can avoid all overhead of server mode additional QSQSRVR jobs. This is a convenience override of db2_(p)connect to set the userid and password values to null without PHP source code changes. This override can be used in combination with ibm_db2.i5_all_pconnect = 1.

  • 0 db2_(p)connect with specified userid and password

  • 1 db2_(p)connect override connect with null userid and null password
