And for Informix, documentation says:
Integrating Informix Server and Data Protector
Configuring the Integration
6 Chapter 1
If you intend to use the Data Protector CLI, set the Data Protector
environment variable OB2BARHOSTNAME to the virtual server name as
follows:
Windows: set OB2BARHOSTNAME=<virtual_server_name>
UNIX: export OB2BARHOSTNAME=<virtual_server_name>
but for DB2 Integration, only:
In Client, select the DB2 Server system. In a cluster environment,
select the virtual server.
