When Trying to Startup iplant Instance the below error Appearing every-time :

TEST siebel: :/Siebel/iPlanet/webserver7/https-Osama_TST/bin\>./startserv
Oracle iPlanet Web Server 7.0.15 B04/19/2012 21:52
info: CORE5076: Using [Java HotSpot(TM) 64-Bit Server VM, Version 1.6.0_24] from [Sun Microsystems Inc.]
startup failure: could not bind to port 8080 (Address already in use)
failure: HTTP3127: http-listener-1: http://TEST:8080: Error creating socket (Address already in use)
failure: HTTP3094: 1 listen sockets could not be created
failure: server initialization failed

From the above error you notice that Port 8080 is already in use.

The Solution :

ps -ef |grep webservd

and Use Kill -9

Try Again Now

ORA-12505 SCAN Listener And JDBC

Image
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
