Oracle SE2 Licensing: The Limits to Check Before You Migrate

The short answer: Oracle Standard Edition 2 (SE2) replaced Standard Edition and Standard Edition One, and it can be licensed only on servers with a maximum of two sockets. Check your servers before you migrate.

The limits of Standard Edition 2

• Two sockets at most. SE2 may only be licensed on servers with a maximum of two sockets.
• Counted by socket, not core. Each occupied socket is one processor licence, whatever the core count. A two-socket server needs 2 licences: $35,000 at list on the 15 September 2026 price list, plus $7,700 a year in support. Enterprise Edition on the same server, with 32 Intel cores, needs 16.
• 16 CPU threads per database. Each SE2 database instance can use at most 16 CPU threads.
• No Real Application Clusters from 19c. RAC was included with SE2 in earlier releases and is not from Oracle Database 19c.
• No options or management packs. The Diagnostics and Tuning Packs can only be licensed with Enterprise Edition, so querying AWR or ASH data on SE2 is a finding with no licence to buy. Set CONTROL_MANAGEMENT_PACK_ACCESS to NONE and use Statspack.

Before you migrate to SE2

Check each server’s socket count, the threads each database needs, whether any database uses RAC, and every option or pack in use. A database that passes all four can move to SE2 for a fraction of the Enterprise Edition price. One that fails any of them stays an Enterprise Edition cost, or becomes an audit finding. Our article on Oracle Database license compliance covers SE2 among the five most common gaps.
