Starting Shell Scripts for ORACLE Export/Import 
SAPDBA uses the ORACLE export/import utilities to export/import tables and their data.
SAPDBA creates shell scripts that can be used to call the export/import programs.
To manually perform an import of tables and their data, for example, enter the following command in the work directory at the prompt:
OS> imp<TSP>.sh
or imp<TSP>_<n>.sh
The files for the unload/load option (
ldr<TSP>.sh ,...) are not genuine shellscripts but merely contain internal SAPDBA information. They cannot be started as separate shellscripts. Unload and load can only be performed with SAPDBA.
