When Streams components(QUEUE,CAPTURE,APPLY,PROP) gets aborted/disabled and if you are not able to recover from the situation, this article can be used. The note just creates the new set of streams components and starts the replication(without exp/imp) from the place, where we stuck.

This cannot be used for all types of streams error. The cause of the error needs to be identified.

For example, if streams component is stuck due to long running transaction, this note will not be helpful. Because, when we create the new setup, still we will hit the same long running transaction. So, in this case, first the long running transaction should be skipped.

Hence, before we use this note, we should do the initial analysis of the problem and understand the problem.

For example, we hit the following error for one customer:

Errors in file /opt/oracle/admin/SHAZAMP/bdump/shazamp_c002_18485.trc:
ORA-00600: internal error code, arguments: [15709], [29], [1], [], [], [], [], []
ORA-00448: normal completion of background process

Stop/start capture did not resolve the issue.

Using the steps mentioned in below note, we were able to recover from the situation

The advantage of this note over general drop/recreate streams is, we skip the exp/imp.
Hence the setup is Quick.
