ORACLE Discoverer usage note
---------------------------------------

Part of 9.0.2 ORACLE9iDS

* What is a EUL? End user layer

Discoverer administrator
--------------------------
1. From DBA account
grant connect, resource to dsadmin identified by dsadmin;
alter user dsadmin default tablespace users quota unlimited on users;
2.
Start administrator connect to dsadmin. Request to create an EUL will be prompted.
Grant EUL to public.

* If you see error about dcmresus.msb not in the "path", chances are the ORACLE_HOME
  environment is not set properly or was overwritten by other ORACLE product installation.
  Reset the environment variables will correct it.

* If you see ora-12705 error complaining about the NLS setting, chances are
  the infamous NLS_LANG setting is messed up. Run regedit to remove 
  NLS_LANG and NLS_PREV_LANG from HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE 

* If the above do not work, it might be easier just to deinstall/reinstall
  9.0.2. The whole process takes only 15 minutes or so. No side effects.

* Note that the NLS_LANG is set to AMERICAN_AMERICA.WE8MSWIN1252 in the registry.
  No environment varaible of NLS_LANG is set.
