Hello, hope to get some help! I´m trying to connect to an oracle 9 on a codeigniter project but it does not work on oracle 9. On oracle 11 xe works fine. If I make a test outside project it connects to oracle 9 but in the  project does not wortk.

$db['default'] = [
    'dsn'  => '',
    'hostname' => '192.168.1.29/xe',
    'username' => 'testdb',
    'password' => 'testdb',
    'database' => 'xe',
    'dbdriver' => 'oci8',
    'dbprefix' => '',
    'pconnect' => false,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => false,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => false,
    'compress' => false,
    'stricton' => false,
    'failover' => [],
    'save_queries' => true
];


parameters oracle 9 that dont work:

$db['default'] = [
    'dsn'  => '',
    'hostname' => '192.168.1.182/tsh1.world',
    'username' => 'testdb',
    'password' => 'testdb',
    'database' => 'tsh1.world',
    'dbdriver' => 'oci8',
    'dbprefix' => '',
    'pconnect' => false,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => false,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',

    'encrypt' => false,
    'compress' => false,
    'stricton' => false,
    'failover' => [],
    'save_queries' => true

Test that worked on oracle 9 :
<?php

$conn=oci_connect("testdb","testdb","192.168.1.182/tsh1.world");

?>


I´m new on php, any tips?

@gutoazeredogyn,

What error message are you receiving?

@gutoazeredogyn,

What error message are you receiving?

Whoops \ Exception \ ErrorException (E_WARNING)

oci_connect(): ORA-12560: TNS:protocol adapter error


Both oracle 11 and oracle 9 are not in the machine with xampp. oracle 11 runs on windows 7 and oracle 9 on a red hat machine

@gutoazeredogyn,

What version of CI? Also, did you run the CI oracle 9 and Test oracle 9 on the same machine?

@gutoazeredogyn,

What version of CI?  Also, did you run the CI oracle 9 and Test oracle 9 on the same machine?

both tests on the same machine running xampp! Just  edited database.php of codeigniter project to test parameters. Test that runned ok on oracle 9 was on a simple projet that tests login and logout using oracle.

using instant client 1.4 and php_oci8.dll. params cheched on phpinfo and as I mentioned, working fine with the login/logout project on oracle 9.

any help?

@gutoazeredogyn,

Try in this file ... system/core/CodeIgniter.php

@gutoazeredogyn,

What version of CI?

I did not istall CI yet, but the project was done on him. Is there any file on the project that I can see the version of CI that it was created?

@gutoazeredogyn,

What is the directory layout? (assuming that you tried looking here system/core/CodeIgniter.php).

@gutoazeredogyn,

Try in this file ... system/core/CodeIgniter.php
