An associative array of connection options that affect the behavior
of the connection, where valid array keys include:
The following new option is available in ibm_db2 version 1.7.0 and later.
The following new i5/OS options are available in ibm_db2 version 1.5.1
and later.
-
i5_lib
-
A character value that indicates the default library that will be
used for resolving unqualified file references. This is not valid
if the connection is using system naming mode.
-
i5_naming
-
DB2_I5_NAMING_ON
value turns on DB2 UDB CLI iSeries
system naming mode. Files are qualified using the slash (/) delimiter.
Unqualified files are resolved using the library list for the job.
DB2_I5_NAMING_OFF
value turns off DB2 UDB CLI default
naming mode, which is SQL naming. Files are qualified using the period (.)
delimiter. Unqualified files are resolved using either the default library
or the current user ID.
-
i5_commit
-
The i5_commit
attribute should be set before the
db2_connect. If the value is changed after the
connection has been established, and the connection is to a remote data
source, the change does not take effect until the next successful
db2_connect for the connection handle.
Note:
The php.ini setting ibm_db2.i5_allow_commit
==0
or DB2_I5_TXN_NO_COMMIT
is the default, but may be
overridden with the i5_commit
option.
DB2_I5_TXN_NO_COMMIT
- Commitment control is not used.
DB2_I5_TXN_READ_UNCOMMITTED
- Dirty reads, nonrepeatable
reads, and phantoms are possible.
DB2_I5_TXN_READ_COMMITTED
- Dirty reads are not possible.
Nonrepeatable reads, and phantoms are possible.
DB2_I5_TXN_REPEATABLE_READ
- Dirty reads and nonrepeatable
reads are not possible. Phantoms are possible.
DB2_I5_TXN_SERIALIZABLE
- Transactions are serializable.
Dirty reads, non-repeatable reads, and phantoms are not possible
-
i5_query_optimize
-
DB2_FIRST_IO
All queries are optimized with the goal of
returning the first page of output as fast as possible. This goal works well
when the output is controlled by a user who is most likely to cancel the query
after viewing the first page of output data. Queries coded with an
OPTIMIZE FOR nnn ROWS clause honor the goal specified by the clause.
DB2_ALL_IO
All queries are optimized with the goal of running
the entire query to completion in the shortest amount of elapsed time. This is a
good option when the output of a query is being written to a file or report, or
the interface is queuing the output data. Queries coded with an OPTIMIZE FOR nnn
ROWS clause honor the goal specified by the clause. This is the default.
-
i5_dbcs_alloc
-
DB2_I5_DBCS_ALLOC_ON
value turns on DB2 6X allocation scheme
for DBCS translation column size growth.
DB2_I5_DBCS_ALLOC_OFF
value turns off DB2 6X allocation scheme
for DBCS translation column size growth.
Note: php.ini setting ibm_db2.i5_dbcs_alloc
==0 or
DB2_I5_DBCS_ALLOC_OFF
is the default, but may be overridden
with the i5_dbcs_alloc
option.
