Failed when I want to create channel on SAP CC

[Former Member]

Hello experts,

I work on this tutorial theese days, and I have problem: I can't create Service channel in SAP HANA Cloud Connector in "On-premise To Cloud" as described here in Step 3 in this tutorial: week4-u3

The problem is that the Local Instance Number can't be 00.

I have to choose between 01 and 99, which would not be by the rules of the tutorial.

I am thankful to you if you could share with me some experience or give me any solution.

Best regards,

Anne.

Hi Anne

The tutorial is wrong about this. The local instance number must be between 01 and 99. The instance number of the HANA database in SAP Cloud Platform is 00, and the local instance number must be different.

So go ahead and choose, say, 01, and then change the port number accordingly. The port number, that your database tool connects to, is 3<local instance number>15, so if you choose 01 as your local instance number, the port number will be 30115.

Hello Morten,

Thank you very much for your answer. Yes, I chose 99 and it's Ok.
But, a colleague of mine has succeeded with the Instance number 00.

Could this be the issue that the socket cannot access to my hana database (in SAP Cloud HANA cockpit) and my applications not to work? I am stuck on this problem several days. My colleague, by setting the instance number 00, doesn't have problem with running his two applications.

Regards,

Anne.

Hi Anne,
this restriction has been introduced in an SCC version that was not released when the tutorial was provided. Using the same instance number on both sides causes trouble, if the client is an ABAP system.

I understand very well and thank you for your wide response.

And, once set up a service channal in SAP Cloud Connector with an Instance number 99, my question is how can I change the Instance number that appears in my Eclipse SAP HANA Developement system? Or, is it even possible to change it to 99? Cause I have noticed that when moving over my IDE with the cursor, I got a table with informations where the Instance number is 00 in my Eclipse SAP HANA Developement system, as shown below in the link:

- https://prnt.sc/jujddv

- http://prntscr.com/jujilj (the port is 30015, and not 39915)

Thank you in advance.

Best regards,

Anne.

Hi Anne

The instance number of the HANA database in the cloud does not (and cannot) change. The local instance number and port number is used, when you connect to the service channel locally. Later in the tutorial you are following, the NetWeaver system connects to the service channel, but you can also connect from a locally installed database tool (like for instance a SQL query tool).
