ORA-12505 SCAN Listener And JDBC

Posted on by Osama Mustafa in Database

The Above Error Appears when trying to connect RAC database Using SCAN Listener through JDBC, I checked everything and it was working without any problem, I could not find any reason why this issue happened, nothing in the Listener.log.

So I Used the below connection String instead of above one.

jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=SCAN-LISTENER-NAME)(PORT=1530))(CONNECT_DATA=(SERVICE_NAME=Service-name)))

Thank you

Change OHS Port On Linux to Work on 80

Posted on by Osama Mustafa in Fusion Middleware

Operating system : Oracle Linux 6.4
Oracle WebTier OHS 11.1.1.7

if you want to configure OHS ( WT ) to work on port 80 ( http ) avoiding insert Port.

For Example :

OHS default Port is 7777, if you want to leave it like this any call for the server should be like this :

http://:7777/console  

But if you are using port 80 you have to do the below :

http:///console 

But on Linux if you need to use port 80 you have to be root, to do this follow the below step :

  • As root user :

[root@TST-WT1 bin]# pwd
/u01/fmw/Oracle_WT1/ohs/bin 

[root@TST-WT1 bin]# chown root .apachectl
[root@TST-WT1 bin]# chmod 6750 .apachectl

  • As Oracle User

[oracle@TST-WT1 ~]$ cd /u01/fmw/admin/config/OHS/ohs1/ 

[oracle@SCADNP-WT1 ohs1]$ ls http*
 httpd.conf      

  • Edit the file using any Editor and modify Listen from 7777 to 80
  • Restart OHS using opmnctl command.
