DB Studio cannot connect to host localhost to register user management

Hello,

I installed MaxDB Database Studio (Version: 7.7.06.09) on Linux (openSUSE 11.1).

On login I get three errors:

1. Connect to UMDB not possible. Try to use/create local default user management.

com.sap.dbtech.jdbc.exceptions.JDBCDriverException: Cannot connect to jdbc:sapdb://server.linux.site/.UMDB [Cannot connect to host localhost:7210 [Verbindungsaufbau abgelehnt], -813.].

2. Recreation default user management failed.

com.sap.dbtech.jdbc.exceptions.JDBCDriverException: Cannot connect to jdbc:sapdb://server.linux.site/.UMDB [Cannot connect to host localhost:7210 [Verbindungsaufbau abgelehnt], -813.].

3. Connect to user management failed.

com.sap.dbtech.jdbc.exceptions.JDBCDriverException: Cannot connect to jdbc:sapdb://server.linux.site/.UMDB [Cannot connect to host localhost:7210 [Verbindungsaufbau abgelehnt], -813.].

I suppose, it has something to do with the network configuration.

Window->Preferences->User Management 'Database node' = 'localhost'.

IPv6 is active on the server and /etc/hosts contains:

::1             localhost ipv6-localhost ipv6-loopback

127.0.0.2       server.linux.site server

127.0.0.1       nil

(and more...)

The vserver is actice (at localhost 7210).

All other network related things work fine on the Server.

I tried several solutions:

1. When I change 'nil' to 'localhost' in /etc/hosts, I get the same error as above.

2. When I change 'localhost' to '127.0.0.1' in 'Database node', Check with 'Reset User Management' and Register the .UMDB Database, I get the error:

Connect failed.

com.sap.dbtech.jdbc.exceptions.JDBCDriverException: Cannot connect to jdbc:sapdb://server.linux.site/.UMDB [Cannot connect to host localhost:7210 [Verbindungsaufbau abgelehnt], -813.].

3. When I change 'localhost' to 'nil' in 'Database node' and register manually to the .UMDB Databse, I get the message:

User management database successfull registered.

Refresh your <Local> server to see the user management database.

But I don't know how to refresh the server (vserver, xserver?) and I can't see any database.

And when I restart the MaxDB Database Studio, I have again 'localhost' in 'Database node' (although 'nil' was saved in /var/opt/sdb/data/app/dbstd/um.properties before) and same problems as above.

Any idea for a solution?

Cheers

Peter
