Hi

i'm connecting to my database via scan name and my scan name resolve to 3 IPs  
but the issue is sometimes 1 or 2 IPs get unavailable  
my question how i can set the connection to retry all IPs as below

```auto
jdbc_connection_string => "jdbc:oracle:thin:@ip1:0000"
if not available retry 
jdbc_connection_string => "jdbc:oracle:thin:@ip2:0000"
if not available retry 
jdbc_connection_string => "jdbc:oracle:thin:@ip3:0000" 

```

thanks

The syntax for an Oracle JDBC connection string is

> "jdbc:oracle:thin:@(description=(address\_list=(address=(protocol=tcp)  
> (port=1521)(host=prodHost)))(connect\_data=(INSTANCE\_NAME=Foo)))"

So I think you should try

> jdbc\_connection\_string =\> "jdbc:oracle:thin:@(description=(address\_list=  
> (address=(protocol=tcp)(port=1521)(host=ip1))  
> (address=(protocol=tcp)(port=1521)(host=ip2))  
> (address=(protocol=tcp)(port=1521)(host=ip3))  
> )(connect\_data=(INSTANCE\_NAME=Foo)))"

See [this](https://docs.oracle.com/cd/E11882_01/network.112/e10835/tnsnames.htm#NETRF263) page for information about the FAILOVER and LOAD\_BALANCE options, one of which you probably want.
