Chapter 3. Beans, BeanFactory and the ApplicationContext

- Supplemental Logging in a Streams Environment
12 Monitoring Streams Replication
- Displaying Supplemental Log Groups at a Source Database
1 Understanding Streams Replication
- Unconditional log groups log the before images of specified columns when the table is changed, regardless of whether the change affected any of the specified columns. Unconditional log groups are sometimes referred to as "always log groups." Conditional log groups log the before images of all specified columns only if at least one of the columns in the log group is changed.
- is the entire column of table stored/ only the respective row?? - post by ravi_eze
1 Introducing Oracle Streams AQ
- Oracle recommends that you use a nonzero wait time for the first dequeue call on a queue in a session, and then use a zero wait time with the
NEXT_MESSAGEnavigation option for subsequent dequeue calls.

11 Managing Logical Change Records (LCRs)
- Also, you can modify an LCR using an apply handler or a rule-based transformation. You can modify both LCRs captured by a capture process and LCRs constructed and enqueued by a user or application.

- Transformations are exported with a schema or a full database export. If an
AQ table is exported the transformation corresponding to the queue table will also be exported.
- The transformation cannot write database state (perform DML) or commit or rollback the current transaction.
