Where DSMI_* variables are set ?

Hi,

DB2 process environment has three vars set:

DSMI_CONFIG

DSMI_DIR

DSMI_LOG

Talking about v8 fp16 instance version.

Where exactly they are set ? - looked for a while but with no success.

Looks like these vars are not set automatically in db2 version from ibm(not sap variant)

thanks

Vilius
