Defining DB2 user and group accounts
Before installing DB2 UDB binaries and creating instances, you must define DB2 UDB user and group accounts for each instance on each system. Note the following requirements:
-
The IDs for DB2 users and groups must be exactly the same across all cluster systems.
-
The DB2 instance owner's home directory, which is the mount point used by the DB2 instance created on shared storage, must exist on each node. If it does not, create the mount point directory on each node.
-
All DB2 user accounts must exist on the local systems. The use of NIS or NIS+ for users is not recommended because these services are not highly available. If their service is interrupted, VCS may not be able to work correctly.
