Rem    NAME
Rem      oramtsadmin.sql - OraMTS administrative SQL script
Rem
Rem    DESCRIPTION
Rem      Oracle administrative SQL script for MSDTC transactions
Rem
Rem    NOTES
Rem      Run this script on Oracle database server side to set up automatic recovery for
Rem      MSDTC transactions.
Rem
Rem      This script creates OraMTS administrator user account on Oracle database
Rem      server. It schedules database jobs for automatic transaction recovery 
Rem      every one minute. When the database job is run, it checks for unresolved
Rem      global transactions in the database that are related to MSDTC. 
Rem      Information in the transaction identifiers of the in-doubt transactions
Rem      identifies the computer on which the transaction was started. The Oracle
Rem      MTS Recovery Service on that computer resolves the transaction. This 
Rem      script also schedules post-recovery cleanup every hour.

Rem prompt the user for the Oracle MTS admin user and password
variable mtsadm_usr varchar2(32);
variable mtsadm_pwd varchar2(32);
variable mtsadm_con varchar2(64);
accept mtsadm_usr default 'mtssys' prompt 'enter the MTS administrator username (default mtssys) =>  '
accept mtsadm_pwd default 'mtssys' prompt 'enter the MTS administrator password (default mtssys) =>  '
accept mtsadm_con default 'local'  prompt 'enter the Net connect string for the database (default local) => '

spool oramts.out
Rem drop the Oracle MTS administrator first
drop user &mtsadm_usr cascade;
Rem create the Oracle MTS adminsitrator anew
create user &mtsadm_usr identified by &mtsadm_pwd;

Rem grant the necessary privileges to the MTS administrator
grant connect, resource, unlimited tablespace, create session to &mtsadm_usr;
grant create synonym, create view, create table to &mtsadm_usr;
grant select_catalog_role to &mtsadm_usr;
grant force any transaction to &mtsadm_usr;
grant execute on dbms_job to &mtsadm_usr;
grant execute on utl_http to &mtsadm_usr;
grant execute on utl_file to &mtsadm_usr;
grant create any directory to &mtsadm_usr;

Rem the following two grants are needed as PL/SQL doesn't use
Rem privileges granted via roles i.e. select_catalog_role.
grant select on sys.dba_pending_transactions to &mtsadm_usr;
grant select on sys.dba_2pc_pending to &mtsadm_usr;
grant select, update, delete on sys.pending_trans$ to &mtsadm_usr;
grant select, update, delete on sys.pending_sessions$ to &mtsadm_usr;
grant select, update, delete on sys.pending_sub_sessions$ to &mtsadm_usr;
grant select on sys.v_$parameter to &mtsadm_usr;
