HELP!!! Connecting to Oracle 9i

[eluser]mhel_dc[/eluser]

Code:

I'm using CI 1.7.2 and I'm trying to connect to Oracle 9i server I've added new database information for oracle since my default database is MySQL:

In my database.php

$active_group = "default";
$active_record = TRUE;

$db['default']['hostname'] = "localhost";
$db['default']['username'] = "user";
$db['default']['password'] = "password";
$db['default']['database'] = "db";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";

$ora['ora9']['hostname'] = "OraSvr";
$ora['ora9']['username'] = "orauser";
$ora['ora9']['password'] = "orapwd";
$ora['ora9']['database'] = "";
$ora['ora9']['dbdriver'] = "oci8";
$ora['ora9']['dbprefix'] = "";
$ora['ora9']['pconnect'] = TRUE;
$ora['ora9']['db_debug'] = TRUE;
$ora['ora9']['cache_on'] = FALSE;
$ora['ora9']['cachedir'] = "";
$ora['ora9']['port']     = 1522;


In my controller:

<?php
    class test extends Controller
    {
        function test(){
            parent::Controller();
            $this->load->database('ora9',TRUE);
        }
        
        function index(){
        
            $qry        =   "Select Count(*) RsCount from SvrCatalog.TableName";
            $this->ora->query($qry);
            
            foreach($this->ora->result_array() as $row){
                echo $row['RsCount'];
            }
        }
    }
?>

When I tried to connect...

This came out :


An Error Was Encountered

You have specified an invalid database connection group.


I can't figure out what went wrong.... Please help.

in database.php

change : $active_group = "default"; to $active_group = "ora9";

or

$active_group = "default";
$active_record = TRUE;

$db['default']['hostname'] = "//hostname/SID";
$db['default']['username'] = "orauser";
$db['default']['password'] = "orapwd";
$db['default']['database'] = "";
$db['default']['dbdriver'] = "oci8";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";

Good Luck!

I don't want to change the current profile for my default connection since my web application basically connects to MySQL it happens that some of the data is stored in oracle, so I've created another database connection profile ... by default the web application is running under MySQL... I just want to connect to oracle when needed... or if possible simultaneous connection between MySQL and Oracle.

keep in mind, that by default, CI's oracle driver does not use configured in config/database.php encoding, so here's a quick hack:

modify file "\system\database\drivers\oci8\oci8_driver.php"

function db_connect()
{
return @ocilogon($this->username, $this->password, $this->hostname, 'AL32UTF8');
}

'AL32UTF8' -is the utf encoding.

this is solution may help you, when you are connecting to oracle with windows-1251 encoding

From CI docs :
----------------------
Connecting to Multiple Databases

If you need to connect to more than one database simultaneously you can do so as follows:
$DB1 = $this->load->database('group_one', TRUE);
$DB2 = $this->load->database('group_two', TRUE);

Note: Change the words "group_one" and "group_two" to the specific group names you are connecting to (or you can pass the connection values as indicated above).

By setting the second parameter to TRUE (boolean) the function will return the database object.

When you connect this way, you will use your object name to issue commands rather than the syntax used throughout this guide. In other words, rather than issuing commands with:

$this->db->query();
$this->db->result();
etc...

You will instead use:

$DB1->query();
$DB1->result();
etc...

You have made a simple mistake

Code:

$db['default']['hostname'] = "localhost";
$db['default']['username'] = "user";
$db['default']['password'] = "password";
$db['default']['database'] = "db";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";

$ora['ora9']['hostname'] = "OraSvr";
$ora['ora9']['username'] = "orauser";
$ora['ora9']['password'] = "orapwd";
$ora['ora9']['database'] = "";
$ora['ora9']['dbdriver'] = "oci8";
$ora['ora9']['dbprefix'] = "";
$ora['ora9']['pconnect'] = TRUE;
$ora['ora9']['db_debug'] = TRUE;
$ora['ora9']['cache_on'] = FALSE;
$ora['ora9']['cachedir'] = "";
$ora['ora9']['port']     = 1522;

change to

Code:

$db['default']['hostname'] = "localhost";
$db['default']['username'] = "user";
$db['default']['password'] = "password";
$db['default']['database'] = "db";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";

$db['ora9']['hostname'] = "OraSvr";
$db['ora9']['username'] = "orauser";
$db['ora9']['password'] = "orapwd";
$db['ora9']['database'] = "";
$db['ora9']['dbdriver'] = "oci8";
$db['ora9']['dbprefix'] = "";
$db['ora9']['pconnect'] = TRUE;
$db['ora9']['db_debug'] = TRUE;
$db['ora9']['cache_on'] = FALSE;
$db['ora9']['cachedir'] = "";
$db['ora9']['port']     = 1522;

You still want the settings inside the $db array. There is no need to change it to $ora.
