Verifying the Replication Agent Replicating State

Verify the replicating state of Replication Agent.

Enter:

resume
go

If the Replication Agent successfully transfers to a replicating state, you see:

State       Action
----------- --------------------------
REPLICATING Ready to replicate data.

The Replication Agent goes to the REPLICATION DOWN state if an error occurs:

isql –Usa –Psa_pass –SSAMPLE_RS
1> resume
2> go
Msg 32000, Level 20, State 0:
Server 'myra', Procedure 'resume', Line 1:
Command <resume> failed - Desired state <REPLICATE>
could not be achieved. Current state: <REPLICATION
DOWN>

The ra_status command returns the state of the Replication Agent. It is good practice to verify that the Replication Agent remains in replicating state, even after the resume command executes successfully.
To detect an error that occurred after replication start-up, execute:
```
ra_status
go
```
If the Replication Agent is in replicating state, ra_status returns:
```
State             Action
----------------- -----------------------
REPLICATING       Ready to replicate data.
```
Replication Agent goes to the REPLICATION DOWN state if an error occurs.
```
isql –Usa –Psa_pass –SSAMPLE_RS
1> resume
2> go
Msg 32000, Level 20, State 0:
Server 'myra', Procedure 'resume', Line 1:
Command <resume> failed - Desired state <REPLICATE>
could not be achieved. Current state: <REPLICATION
DOWN>
```

Validate that both primary and replicate connections are active:

isql –Usa –Psa_pass –SSAMPLE_RS
admin who
go

Note: Be aware that:

The DSI connection for the primary database connection is usually suspended because you are not replicating data back to the primary database.
The Replication Agent connection, if established for the replicate database connection, is usually down, because you are not replicating data from the replicate database.

Do not proceed until admin who returns status for threads similar to this:

admin who
go

You see:
