For Oracle databases, a sample script is provided in the the file DatabaseNotify_Oracle.sql in the Repository/Component/CtsComponents subdirectory of your EAServer installation. The sample script below is for Sybase Adaptive Server Enterprise. Modifications are required for use on other databases:
use master
go
if not exists (select name from sysdatabases where name = "notifydb")
begin
create database notifydb
exec sp_dboption notifydb, "trunc log on chkpt", "true"
end
go
use notifydb
go
checkpoint
go
if not exists (select 1 from sysobjects where name="cms_notify" and type="U")
begin
create table cms_notify
(
id numeric(16,0) identity primary key,
type char(1) not null,
name varchar(100) not null,
message varchar(255) not null,
options varchar(255) not null
)
end
go
if not exists (select 1 from sysusers where name="guest")
exec sp_adduser guest
go
use sybsystemprocs
go
if exists (select 1 from sysobjects where name="sp_notify" and type="P")
drop proc sp_notify
go
create proc sp_notify

return
end
