Symptoms

Customer has a XStreams XOut configuration in a single instance 11.2.0.3 database.

The required_checkpoint_scn of the XStreams Capture process is not changing over time, despite the Capture progressing.

Long running open transactions which never end are observed in the Streams healthcheck report under the section 

++ OPEN STREAMS APPLY TRANSACTIONS ++ 

The transactions are for DDL associated with analyze statements which the XStream Capture is not interested in which indicates that this is a different issue to that discussed in <Note 1412928.1>.
