Hi guys
i have one question about switchover cmd . For example, i have 1 primary database called stdby3 and 2 standby databases that are called stdby1 and stdby2. When i performed switchover cmd to stdby2 standby database, why the new primary and standby databases are closed (not mount) after the switchover process is completed


output screen:

DGMGRL> show configuration;

I thought I had all configured right but I can't get DG broker
to bring up the databases:

You may need to configure the service name (instead of 'SID_NAME') also in the tnsnames.ora file.

These are your VALID (configured) services:
Service "SND_S" has 1 instance(s).
Service "SND_S_DGB" has 1 instance(s).
Service "SND_S_DGMGRL.WORLD" has 1 instance(s).
Service "SND_S_XPT" has 1 instance(s).

Configure the service name in the tnsnames.ora file?
Here is what is in the tnsnames.ora file now:

LISTENER_SND.WORLD =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = sapsnd)(PORT = 1527))

SND.WORLD =
(DESCRIPTION =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = sapsnd)(PORT = 1527))
(CONNECT_DATA = ( SID = SND ) ( GLOBAL_NAME = SND.WORLD )
) )

SSND.WORLD =
(DESCRIPTION =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = sapsnddg.ssmhc.com)(PORT = 1527))
(CONNECT_DATA = (SID = SND) (GLOBAL_NAME = SSND.WORLD)
) )


And the listener.ora file:

LISTENER =
(ADDRESS_LIST =
(ADDRESS =
(COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = sapsnd)(PORT = 1527)
) )
STARTUP_WAIT_TIME_LISTENER = 0
CONNECT_TIMEOUT_LISTENER = 10
TRACE_LEVEL_LISTENER = OFF
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME=SND_P_DGMGRL.WORLD)
(SDU = 32768)
(SID_NAME = SND)
(ORACLE_HOME = /oracle/SND/102_64)
) )
SUBSCRIBE_FOR_NODE_DOWN_EVENT_LISTENER=OFF


---------------------------------------------
I am still not sure what service(s) I am missing.
The SID is the same on both servers (SND) while the unique names are SND_P and SND_S.

Thanks for your help!
p.s. These are after a revision. I took out the SERVICE_NAME entry hoping that was the issue.

11g needs service name:

SND.WORLD =
(DESCRIPTION =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = sapsnd)(PORT = 1527))
(CONNECT_DATA = (SERVICE_NAME = SND) ( GLOBAL_NAME = SND.WORLD )
) )

SSND.WORLD =
(DESCRIPTION =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = sapsnddg.ssmhc.com)(PORT = 1527))
(CONNECT_DATA = (SERVICE_NAME = SSND) (GLOBAL_NAME = SSND.WORLD)
) )

I removed SID and replaced it with SERVICE_NAME. Now I can't get into DGMGRL:

DGMGRL> connect sys/********@snd_p

-----------------------
New tnsnames.ora:
LISTENER_SND.WORLD =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = sapsnd)(PORT = 1527))

SND.WORLD =
(DESCRIPTION =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = sapsnd)(PORT = 1527))
(CONNECT_DATA = ( SERVICE_NAME = SND ) ( GLOBAL_NAME = SND.WORLD )
)
)

SSND.WORLD =
(DESCRIPTION =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = sapsnddg.ssmhc.com)(PORT = 1527))
(CONNECT_DATA = (SERVICE_NAME = SSND) (GLOBAL_NAME = SSND.WORLD)
)
)

---------------------------------------------
Though I don't have a SERVICE of that name according to this output. Where did my SND connection go? Should it be in the LISTENER.ORA?

Service "SND_P" has 1 instance(s).
Service "SND_P_DGB" has 1 instance(s).
Service "SND_P_DGMGRL.WORLD" has 1 instance(s).
Service "SND_P_XPT" has 1 instance(s).

Does your sqlnet.ora file have the following?:

NAMES.DEFAULT_DOMAIN=world

Yes.

AUTOMATIC_IPC = ON
TRACE_LEVEL_CLIENT = OFF
SQLNET.EXPIRE_TIME = 0
NAMES.DEFAULT_DOMAIN = WORLD
NAME.DEFAULT_ZONE = WORLD

I also found this:
If you are using a nondefault port number (for example, 
something other than port 1521) for the local listener address, 
you must set the LOCAL_LISTENER initialization parameter on each 
instance that is part of a broker configuration to a listener 
address that is reachable by all members of the configuration. 

To enable DGMGRL to restart instances during the course
of broker operations, a service with a specific name must be
statically registered with the local listener of each instance. 
The value for the GLOBAL_DBNAME attribute must be set to a 
concatenation of db_unique_name_DGMGRL.db_domain. For example, 
in the LISTENER.ORA file:

LISTENER = (DESCRIPTION = 
     (ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=host_name)
     (PORT=port_num))))
SID_LIST_LISTENER=(SID_LIST=(SID_DESC=(SID_NAME=sid_name)
     (GLOBAL_DBNAME=db_unique_name_DGMGRL.db_domain)
     (ORACLE_HOME=oracle_home)))


Which I have done since I use port 1527.
