Minimum Oracle database patches required for the database server

Note: The patches for the Oracle Database Server and the Oracle Client have been set so that both the database and the client use version 4 “TSTZ” (timestamp/time zone) files. The version of these files should always match. This needs to be taken into consideration when applying future patches to the database or client.

If a future patch for either the database or client changes the version of these files, then the patches for both the client and database should be reviewed.

Oracle Windows patches

When a physical machine serves as more than one type of server, you will need all the patches that are required for each type of server. For example, in a single-tier Central Designer installation, the machine that both the Central Designer Server and the Database Server are installed on requires all the patches listed under both the Oracle database and the Oracle client.
