Which four factors can influence the rate of SQL apply on a logical standby database?

Athe number of PREPAER processes

Bthe number of coordinator processes on the standby database instance

Cthe number of full table scans performed by SQL apply

Dthe size of the undo tablespace on the logical standby database

Ethe number of applier processes

Fthe size of the shared pool

Show Suggested Answer

Suggested Answer: A, B, C, E

The rate of SQL apply on a logical standby database can be influenced by:

A: The number of PREPARER processes (which seems to be a typographical error and should read as PREPARER or similar) which prepare the redo data for the applier processes.

B: The number of coordinator processes on the standby database instance which coordinate the SQL apply activities.

C: The number of full table scans performed by SQL apply since full table scans can be resource-intensive and slow down the apply rate.

E: The number of applier processes which apply the redo data to the logical standby database.

Option D is incorrect as the size of the undo tablespace on the logical standby database is more likely to affect the SQL apply lag rather than the rate of SQL apply.

Option F is incorrect because the size of the shared pool would typically not influence the rate of SQL apply. The shared pool is more related to the caching of shared SQL and PL/SQL code and control structures.

Hmm, I'm not so sure about the full table scans. Wouldn't that depend more on the queries being executed rather than the SQL apply process itself?

E) the number of applier processes should not be underestimated.

Wow, this question is tricky! I'm not too sure about the right answer, but I think the number of PREPARE processes and the number of applier processes could definitely impact the SQL apply rate.
