Hello All,

I am having trouble connecting to my HANA server and getting the following error. I have successfully installed HANA Studio but while connecting to the server it is not allowing me:

"database connection is not available", SAPcontrol request failed.

HANA Sudio version is 1.0.26. I tried with both the java versions:

java.version=1.6

java.version=1.7

 

Please advice.

 

Rgs,

Parth.

    While adding the system, have you changes your password?

    If yes, please delete the added system and try to add the system with same user id and new password.
