The document type definition (dtd file) for OPI, the iss500.ctl control file, and the iss500.par parameter file can all be found in the following directory:
%SMAT_HOME%\SQL\OPI
All directories required for Smart Materials log files must be configured correctly in the instance initialization parameter file, named init.ora.
Before you can use the OPI interface, several DBA settings and project defaults need to be configured.
