1. For setting the org context:

begin
fnd_client_info.set_org_context(204);
MO_GLOBAL.init(‘appl’);
end;
MO_GLOBAL.init :
Manages Initialization code for Organization Security Policy.

2. For setting global initialization :

In PL/SQL :

begin
fnd_global.apps_initialize(&user_id,&responsibility_id,&responsibility_application_id);
mo_global.init(‘&product_short_name’);
end;

In SQL :
execute fnd_global.apps_initialize(&user_id,&responsibility_id,&responsibility_application_id);
execute mo_global.init(‘&product_short_name’);

you can get these values through this query

SELECT USER_ID,RESPONSIBILITY_ID,RESPONSIBILITY_APPLICATION_ID, SECURITY_GROUP_ID
FROM FND_USER_RESP_GROUPS
WHERE USER_ID = (SELECT USER_ID FROM FND_USER WHERE USER_NAME = ‘&user_name’)
AND RESPONSIBILITY_ID = (SELECT RESPONSIBILITY_ID FROM FND_RESPONSIBILITY_VL WHERE RESPONSIBILITY_NAME = ‘&resp_name’);

and then these two query

execute fnd_global.APPS_INITIALIZE (USER_ID, RESP_ID,RESP_APPL_ID);
execute mo_global.init(
