The use of OTE open TCBs improves performance, reduces costs, and exploits the benefits of OTE processing.

If you experience poor response times for any of the following reasons, migrating to a Threadsafe environment is especially important:

This section provides information about how OTE provides increased throughput with concurrency, improved performance, benefits of backward compatibility, and considerations when migrating to OTE.
