Which ports are needed for SAP HANA Studio - HANA DB communication?

Question

I want to connect SAP HANA Studio to a HANA instance. The HANA instance number is 40.
The SAP note 1592925 states that the ports 5$$13/5$$14 and 3$$15 should be open to allow communication between the HANA Studio and the HANA database. I even see the instance in the HANA Studio, but I cannot administrate it and the HANA studio gives this general "I don't want you to know what the error actually is" message:
!ENTRY com.sap.ndb.studio.navigator 4 1 2012-01-16 14:01:40.627
!MESSAGE [HDB hostname 40 (SYSTEM)] Error on refreshing system
!SUBENTRY 1 com.sap.ndb.studio.navigator 4 0 2012-01-16 14:01:40.627

Do I need to open any other ports to make HANA Studio work with HANA DB?

Answer 1

Hi Mark,
The HANA Studio connects to HANA DB Instance with JDBC on port 3<Instance number>15.
For your HDB with Instance Number 40, the port would be 34015.
HANA Studio will automatically assign the JDBC port number when you assign the instance number when you add new system.
Looking at the error message that you posted:
!ENTRY com.sap.ndb.studio.navigator 4 1 2012-01-16 14:01:40.627
!MESSAGE [HDB hostname 40 (SYSTEM)] Error on refreshing system
It looks like the hostname entry was not entered correctly (you might have entered "hostname" value when adding the system in HANA Studio).
Here is an example of correct log entry on DCA database instance on hanasvr-01 server with Instance number 00:
!ENTRY com.sap.ndb.studio.navigator 4 1 2012-01-10 13:55:23.598
!MESSAGE [DCA hanasvr-01 00 (SYSTEM)]
You may want to delete and re-add your HDB instance in your HANA Studio.
