Using ON-Bar Environment Variables with ISM

The following environment variables, when set in the ON–Bar environment, determine whether ISM uses compression or encryption when backing up data.

Dynamic Server

You can set these environment variables in the onbar script file. For example:

ISM_COMPRESSION=TRUE; export ISM_COMPRESSION

End of Dynamic Server

Extended Parallel Server

You can set these environment variables in the start_worker script file. Insert the lines that contain the environment variables before the line that starts the onbar_w utility.

End of Extended Parallel Server

Environment Variable in Effect When ON-Bar Issues a Request	Effect on ISM Server Processing for That Request
ISM_COMPRESSION	If this variable is set to TRUE in the environment of the onbar process making a request, the ISM server uses a data-compression algorithm to store or retrieve the data specified in that request. If it is set to FALSE or is not present, the ISM server does not use compression.
ISM_ENCRYPTION	If this variable is set to TRUE or XOR in the environment of the onbar process making a request, the ISM server uses encryption to store or retrieve the data specified in that request. If it is set to NONE or is not present, the ISM server does not use encryption.
ISM_DEBUG_LEVEL	If this variable is set in the ON-Bar environment, it controls the level of reporting detail recorded in the XBSA messages log. The XBSA shared library writes to this log. You can specify a value between 0 and 9. If this environment variable is not set, has a null value, or has a value outside of this range, the detail level equals 1 by default. A detail level of 0 suppresses all XBSA debugging records. A level of 1 reports only XBSA failures.
