ORA-12537 Error in PERMS Integrator

When testing the Oracle connection or when going to MILPO Orders or RPAM, you could get this error:

ORA-12537: TNS: connection closed

This is caused by the Oracle server refusing to allow a connection from the PERMS Integrator workstation's IP address.  Make sure the workstation has a static IP address, then get your RCAS DBA to add your workstation's IP address into the SQLNET.ORA file on the RCAS database server.
