Dear All,

Is there any view through which we can able to find out the number of log generation for the particular update or insert statements, IN LOGICAL STANDBY?



Regards,
Ishika

No there is none, you can do it with Log Miner at the primary site, or using a handler on the transmitted logical record to count the rows and store the result somewhere or you can add a trigger on the primary on insert or update to get the count of modified rows.

What actual problem are you trying to solve?

Dear Michel,

Since there was huge records got updated during the scheduled batch, at night. So, it's client requirement to know the log creation based on the update stmt.

There is no such thing as log creation for an update. You have log creation for database activity and log records generation for a statement. This later information is not directly available. You can investigate the "solutions" I posted.

But the problem is the huge update.
How many is "huge"? what percentage of table?
Maybe another solution than knowing the number of redo records as, anyway, what can you do with this information?
So, once again, "What actual problem are you trying to solve?"
