Backing Up Oracle - Computing at Cornell

Table 2 lists the most important environment variables.
Table 2. TDP for Oracle environment variables
DSMO_NODE This is used to specify a unique node name for TDP for
Oracle. The value can contain a string of 1 to 64 characters.
The default value is the value returned by the UNIX
hostname command.
TDP for Oracle does not use the node name in the dsm.sys
file.
DSMO_AVG_SIZE This is the average size of an object in MB. This information
is passed to the TSM server, where it is used to determine
storage pool usage and device usage. The default is 50 MB.
Important: It is recommended that you set the variable to
a value larger than your estimated object size. This enables
the TSM server to use the correct storage pools (disk or
tape) from the beginning of the backup.
DSMI_ORC_CONFIG This points to the user option file dsm.opt.
If the variable is not set, TDP for Oracle tries to source
dsm.opt from the default TSM API installation directory.
DSMI_LOG This points to a directory that contains the TSM API error log
file dsierror.log.
Make sure that the user who is performing backups has the
necessary authorization to add or modify the file here.
DSMO_FS This contains the filespace name used on the TSM server.
You can use different filespace names to make use of
different management classes.
The default filespace name is /adsmorc.
DSMO_OWNER This option specifies a session owner name and object
owner name. The value can contain a string of 1 to 64
characters.
The default value is the value returned by the UNIX id
command.
DSMO_DEBUG=49 When set, TDP for Oracle will create a file called
orcagent.log in $ORACLE_HOME/dbs containing useful
trace information.
