User account requirements

Before you install the CDC Replication Engine for Informix®, you need to ensure that user accounts requirements have been satisfied.

Setting up a Windows user account

If you are installing CDC Replication on a Windows system, you must set up a new, or decide on an existing Windows account that you will use to install, configure, or upgrade CDC Replication.

Setting up a UNIX user account

When you are installing CDC Replication on a UNIX machine, you must set up a new, or decide on an existing UNIX account that you will use to install, configure, or upgrade CDC Replication. You can install CDC Replication in the directory of your choice, however, it must be owned by the UNIX account.

Informix database user account

The database user account must be a part of the informix group and must be granted DBA privileges on the database.

Understanding the Informix database requirements

To meet the database requirements for using Informix Change Data Capture to replicate data, you must have the following:

An Informix database with which you want to replicate data on your system. See the IBM Informix Getting Started Guide if you have not installed the product and have not set up an Informix database.
Both the sysmaster and sysadmin databases in your Informix instance in order to successfully replicate data using CDC Replication. For information on these databases, see the IBM® Informix support documentation.
