Problem using digfferent database

Hi, when I am trying to connect to an Oracle DB, using the 01_basic_init_connector.php, rewritten as follows:

include $_SERVER[‘DOCUMENT_ROOT’].“sh/mod/start.inc.php”;
include (‘…/config.php’);
include (‘…/…/codebase/scheduler_connector.php’);

echo "<pre>UserID = ".$user['UID']."\n";

// $res=mysql_connect($mysql_server,$mysql_user,$mysql_pass);
// mysql_select_db($mysql_db);
$res = oci_connect(‘ops$pastrade’, “pastrade”, “apol-sa03/apop”);
echo “1\n”;
#$res=mysql_connect(“localhost”,“root”,“”);

mysql_select_db(“test”);

$scheduler = new schedulerConnector($res);
echo "2\n";
$scheduler->enable_log("log.txt",true);
$scheduler->render_table("apk_usr_agenda","apk_uag_id","startzeit,endzeit,event_title,notizen");
echo "3";

I get as an output:

UserID = 5
1
2

SELECT startzeit FROM apk_usr_agenda

mysql_query(): supplied resource is not a valid MySQL-Link resource at C:\Apache24\htdocs\crm-dev\public\scheduler\codebase\db_common.php line 964

mysql_error(): supplied resource is not a valid MySQL-Link resource at C:\Apache24\htdocs\crm-dev\public\scheduler\codebase\db_common.php line 965

!!!Uncaught Exception
Code: 0
Message: MySQL operation failed

I am sure that I’m doing something wrong… what?

Oracle DB structure:

SQL> desc apk_usr_agenda
Name Null? Type


APK_UAG_ID NOT NULL NUMBER(15)
APK_USR_ID NOT NULL NUMBER(15)
APK_CON_ID NUMBER(15)
APK_CMP_ID NUMBER(15)
APK_KTY_ID NUMBER(15)
EVENT_TITLE NOT NULL VARCHAR2(255)
STARTZEIT NOT NULL DATE
ENDZEIT DATE
CONTACT_DATA VARCHAR2(100)
NOTIZEN CLOB
CREATION_DATE NOT NULL DATE
CREATED_BY NOT NULL VARCHAR2(30)
LAST_UPDATE_DATE NOT NULL DATE
LAST_UPDATED_BY NOT NULL VARCHAR2(30)
APK_UAG_UAG_ID NUMBER(15)
PRIVATE NOT NULL NUMBER(1)

You can change the init code like next

include ('../../codebase/db_oracle.php');
$scheduler = new schedulerConnector($res, "Oracle");

Works, thx!
Now I only need to rewrite the scheduler so as to use my fields.
