Issue: New Users were trying to access a 3-node RAC Oracle Database system using SQLDeveloper
Below is the connection string provided to user for Oracle Database Connection. RAC Virtual IP is provided to connect to Database.
TESTDB01=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=test001-vip1.domain.com)(PORT=1521))
(ADDRESS=(PROTOCOL=tcp)(HOST=test002-vip1.domain.com)(PORT=1521))
(ADDRESS=(PROTOCOL=tcp)(HOST=test003-vip1.domain.com)(PORT=1521))
(CONNECT_DATA=
(SERVICE_NAME=TESTDB01)
(INSTANCE_NAME=TESTDB01)
)
)
User tried to connect using one of the VIP and got the below error in SQLDeveloper.
Status : Failure -Test failed: IO Error: The Network Adapter Could Not Establish The Connection.
Analysis:
Verified the Oracle Database Services and Listener Services are running fine.
Other Users were able to connect to SQLDeveloper using the same Connection String.
Solution:
User does not have network communication open to port 1521 on Oracle RAC Virtual IP.
ping test001-vip1.domain.com
ping test002-vip1.domain.com
ping test003-vip1.domain.com
telnet test001-vip1.domain.com 1521
telnet test002-vip1.domain.com 1521
telnet test003-vip1.domain.com 1521
Ping to VIP address works fine but Telnet to port 1521 on the VIP address is giving “Connect Failed” Error.
When Network communication is opened on port 1521 on all the Oracle RAC Virtual IP servers/Addresses, User can connect to Oracle Database using SQLDeveloper.
