oci_set_editionSets the database edition Description
bool oci_set_edition(string
$edition )Sets the database "edition" of objects to be used by a subsequent connections. Oracle Editions allow concurrent versions of applications to run using the same schema and object names. This is useful for upgrading live systems. Call oci_set_edition before calling oci_connect, oci_pconnect or oci_new_connect. If an edition is set that is not valid in the database, connection will fail even if oci_set_edition returns success. When using persistent connections, if a connection with the requested edition setting already exists, it is reused. Otherwise, a different persistent connection is created Parameters
Return Values
Returns Examples
Example #1 Two scripts can use different versions of myfunc() at the same time
Notes
Caution
Persistent connectionsTo avoid inconsistencies and unexpected errors, do not use ALTER SESSION SET EDITION to change the edition on persistent connections. Caution
DRCP Connection PoolingTo avoid inconsistencies and unexpected errors when using editions and DRCP with Oracle 11.2.0.1, keep a one-to-one correspondence between the oci8.connection_class and the edition name used by applications. Each pooled server of a given connection class should only be used with one edition. This restriction has been removed with Oracle 11.2.0.2. |
