Group or permission issue.

1. Run newgrp DBA to switch primary user group to DBA for the owner of shareplex binary. The newgrp utility creates a new shell execution environment with a new real and effective group identification

UNIX: newgrp DBA
UNIX: id

It should show the effective group for this user is now DBA.

2. Run ora_setup from the proddir/bin directory
./ora_setup
