Setting up security
Set up the required security before you install WebSphere® Message Broker.
After installation, check the topics under the Security heading in the information center to review and implement the security requirements for additional users doing other tasks.
Security control of WebSphere Message Broker components, resources, and tasks depends on the definition of users and groups of users (principals) to the security subsystem of the operating system. Check that you have the correct authority, and that the required principals are in place, before you install WebSphere Message Broker.
User ID restrictions: some operating systems and other products impose restrictions on user IDs:
- On Windows systems, user IDs can be up to 12 characters long, but on Linux, UNIX, and z/OS® systems, they are restricted to eight characters. Database products, for example DB2®, might also restrict user IDs to eight characters. If you have a mixed environment, ensure that the user IDs that you use within the broker environment are limited to a maximum of eight characters.
- Ensure that the case (upper, lower, or mixed) of user IDs in your broker environment is consistent. In some environments, uppercase and lowercase user IDs are considered the same, but in other environments, user IDs of different case are considered unique. For example, on Windows the user IDs 'tester' and 'TESTER' are identical, but on Linux and UNIX systems they are recognized as different user IDs.
- Check the validity of spaces and special characters in user IDs to ensure that, if used, these characters are accepted by all relevant systems and products in your broker environment.
If your user ID does not conform to these restrictions, you might have problems with installation or verification. If so, use an alternative user ID, or create a new one, to complete installation and verification.
Set up the security appropriate to the operating systems that you are using:
- If you are installing on Linux or UNIX systems, go to Security on Linux and UNIX systems.
- If you are installing on Windows, go to Security on Windows systems.
- If you are installing on z/OS, go to Security on z/OS systems.
