Recently I have been playing around with my test database. It has dataguard replication set up and I am always making changes, testing things out etc.
I noticed the other day once I had set replication back up that I was seeing a lot of errors with ORA-16826: apply service state is inconsistent with the DelayMins property.
I done a quick google around, and a couple of sites were recommending stopping the apply services ands restoring standby database again with the current control file. It also mentioned to start a new recovery session.
Luckily enough this was a very simple resolution on this occasion. I loaded DGMGRL and ran the following commands
DGMGRL> connect /Connected.DGMGRL> show configuration
