how to enable MOAC for custom concurrent program ?

Hello Guru's

I have a custom concurrent program based on a sql executable.

I want to enable it to retrieve data for multiple orgs.

I have done following already

1. created security profile and added the three orgs i need to the profile, ran '  list maintenance' program for that profile.

2. added security profile to responsibility, added concurrent program to request group of that responsibility.

3. in sql program added the following

mo_global.init('AR');
  mo_global.set_policy_context('M',NULL);

4. in system administration , selected  'Multiple' in operating unit parameter in concurrent > request tab.

5. in the sql program , i have used synonyms ( without _all )
