The security of IBM App Connect
Enterprise components,
resources, and tasks depends on the definition of users and groups
configured in the operating system.
Some operating systems and other products impose restrictions on
the structure and composition of user IDs:
- On Windows systems, user
IDs can be up to 12 characters long, but on Linux and UNIX systems
they are restricted to 8 characters. Database products, for example DB2®, might also restrict user IDs
to 8 characters. If you have a mixed environment, ensure that the
user IDs in the IBM App Connect
Enterprise environment
are limited to a maximum of 8 characters.
- Ensure that the case (upper, lower, or mixed) of user IDs in your IBM App Connect
Enterprise 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 IBM App Connect
Enterprise 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.
Understand the security requirements that are associated with the
operating systems that you are using:
When you have installed IBM App Connect
Enterprise,
check the Security topics in the IBM App Connect
Enterprise product documentation to review
and implement the security requirements for the performance of other
tasks; see Security.
