You can pass ESSCMD commands to Essbase using the ESSCMD command-line interface. The ESSCMD interface is installed with Essbase Administration Server in:
EAS_HOME\server\bin\esscmd.exe (EAS_HOME/server/bin/esscmd on UNIX)
where EAS_HOME is the directory to which Administration Services is installed.
ESSCMD is also installed with Essbase. For information about using ESSCMD, see the Oracle Essbase Database Administrator's Guide.
