Environment variables

Environment variables determine where IBM Storage® Protect clients create program files.

The following environment variables set the location of space management client program files. The environment variables cannot be set to the root directory.

Table 1. Environment Variables
Variable	Description
DSM_DIR	Points to the resource files, the dsm.sys file, and the executable file, dsmtca. If you do not set the DSM_DIR variable, the space management client searches for the executable files in the installation directory.
DSM_CONFIG	Points to your dsm.opt options file. If you do not set the DSM_CONFIG variable, the space management client searches for the options file in the directory to which the DSM_DIR variable points. If you do not set the DSM_DIR variable, the space management client searches for the options file in the installation directory.
DSM_LOG	Points to the directory of the dsmerror.log log file. The error log file contains information about any errors that occur during processing. If you define the DSM_DIR variable but you do not define the DSM_LOG variable, messages are written to the dsmerror.log log file in the directory that you specified in the DSM_DIR variable. If you do not define theDSM_LOG variable or the DSM_DIR variable, error messages are written to the dsmerror.log log file in the current directory. You receive a warning message if IBM Storage Protect cannot write messages to the log file. Processing continues.
