Prerequisites for installing DB2 UDB, non-MPP versions
Verify all systems have enough resources, such as shared memory, to run DB2 UDB. Check the DB2 memory requirements, which vary depending on the version and hardware configuration of DB2. The DB2 UDB system binaries are to be installed locally and the DB2 UDB database instances are to be installed on shared storage.
Install and configure VCS version 5.0. Refer to the Veritas Cluster Server Installation Guide for instructions on running either the installer or the installvcs utility.
Before installing DB2 UDB, define DB2 UDB user and group accounts.
