Get tips and techniques for building more efficient Ruby on Rails applications on Oracle Database, from tweaking connection parameters to using execution plans and indexes.
Hi,
I am a php developer and I decided to learn ruby on rails.
I have a few question.
I have an ubuntu virtual machine with lamp.
It mean that it has alrweady php and when I access the ip of the machine from my browser it does load the index.php.

OCI_SET_MODULE_NAME(3)OCI_SET_MODULE_NAME(3)oci_set_module_name - Sets the module nameSYNOPSIS
bool oci_set_module_name (resource $connection, string $module_name)
DESCRIPTION
Sets the module name for Oracle tracing.
The module name is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement
is executed.
The name can subsequently be queried from database administration views such as V$SESSION. It can be used for tracing and monitoring such
as with V$SQLAREA and DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE.
The value may be retained across persistent connections.
PARAMETERS
o $connection
-An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).
o $module_name
- User chosen string up to 48 bytes long.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
NOTES
Note
Oracle version requirement
This function is available when PHP is linked with Oracle Database libraries from version 10 g onwards.
Tip
Performance
With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO pack-
age. This is less efficient than using oci_set_client_info(3).
Caution
Roundtrip Gotcha
Some but not all OCI8 functions cause roundtrips. Roundtrips to the database may not occur with queries when result caching is
enabled.
EXAMPLES
Example #1
Setting the module name
<?php
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the module
oci_set_module_name($c, 'Home Page');
// Code that causes a roundtrip, for example a query:
$s = oci_parse($c, 'select * from dual');
oci_execute($s);
oci_fetch_all($s, $res);
sleep(30);
?>
// While the script is running, the administrator can see the
// modules in use:
sqlplus system/welcome
SQL> select module from v$session;
