The connection-destination host name might not correspond with the alias IP address used for HADB client-server communication.

Check whether a host name is specified that corresponds to the alias IP address used for communication between HADB clients and HADB servers.

Check the locations where the host name of the connection destination for the application is specified, such as the client definition, and correct the host name if necessary.

2

The number of concurrent application executions might have exceeded the maximum number of concurrent connections allowed for the HADB servers in the multi-node configuration.

Procedure:

  2. Increase the value specified for the adb_sys_max_users operand in the server definition.

  3. Start the HADB servers in the multi-node configuration.
