NSR-ORA on LINUX

You need ksh to use NSR-ORA. This means that the pdksh package must be installed on the LINUX computer. If the NSR-ORA backup is to be analyzed with set -xin the scripts, we recommend you use the ksh supplied with NSR-ORA. pdksh-5.2.14-1contains an error in this regard, which can cause ksh to crash.

However, this error has already been reported to pdksh development and should be rectified in later versions. The fix is already integrated in the ksh that has been supplied.
