How to configure Splunk DB Connect connection type to dedicated rather than the default shared mode?

New Member

Hi all,

I am usind the app Splunk DB Connect (version 1.0.8) to connect to a Oracle DB to fetch production data.
The issue is: the app establishes a connection link in shared mode by default.

I need to set the connection type to dedicated. Here you can find an example of the connection string I need to set up:

(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=XXXXXX-XXXXXX.it)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=XXXXX-XXXXXX.it)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=XXXX-XXXXXXXXX.it)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XXXXXX.XXXXX.it)))

How can I solve this configuration issue?

Thanks in advance for help.
Kind regards,
Antonio

So there are two easy ways to make this work. The solution posted by Bert F works fine if you don't need to supply any other special Oracle-specific connection properties. The format for that is:

jdbc:oracle:thin:@//HOSTNAME:PORT/SERVICENAME

However, if you need to supply other Oracle-specific connection properties then you need to use the long TNSNAMES style. I had to do this recently to enable Oracle shared connections (where the server does its own connection pooling). The TNS format is:

jdbc:oracle:thin:@(description=(address=(host=HOSTNAME)(protocol=tcp)(port=PORT))(connect_data=(service_name=SERVICENAME)(server=SHARED)))

see this link below, it can help you very fine:

Unfortunately, Splunk constructs the JDBC Thin connection URL internally based on the username/password/service name parameters provided in the database.conf file. There doesn't appear to be way to provide any other details in the file specification. As such I don't think you can currently provide the sort of detailed connection information you specify above.

It also appears that there is no way to define a shared/dedicated preference on a service name basis on the server side of the connection, so if you can't override the default from the client then you're pretty much stuck with the server's default. Is there a particular reason you need to have a dedicated session instead of a shared one?

I've never done this, but it might be possible to configure a second network listener on the database server and only register it to connect dedicated server sessions (i.e. not register it with the dispatcher).

Thank you pmdba for the reply (sorry for my delay in answering). We decided to open a case related to the app to configure the change from the client side of the connection (i.e. have the opportunity to modify that parameter).

Thank you for your support.
Kind regards,
Antonio
