Hi All
I have a dataguard standby (12.2.0.1) that is reporting Transport and apply
lag since this morning
The Network team have looked at the link and can not see anything obviously
wrong.
My alert log does not show anything going wrong.
As you can see below there is movement..I can check from the database that
logs are getting across and applied, just slow
Any pointers as to what I can check next?
