I am about to undertake this - setting up DG for an SAP environment. We are running HP-UX and Oracle 9.2.0.4.

Any gotchas? Anything I need to be aware of SAP/ORacle wise before I start?

Thanks!
Vince

Hi,

I cannot think of any. DataGuard is completly transparent to the application. So, SAP will be unaware of the fact that you are using DataGuard.

Best regards.

If it is an option, use 10gR1 instead of 9iR2.

Thanks for the replies. We are running 9.2.0.6 right now and doesn't look like I will have the chance to upgrade it. Last time I checked SAP didn't say 10 was SAP ready.... that might have changed recently.

Thanks again - I will post how it goes.

I can't seem to get the tnsnames.ora and listener.ora to be 'correct' when I go to add the failover server.

Here is the working listener.ora when SND is the only system listed:

LISTENER =
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=IPC)(KEY= SND.WORLD)
)
(ADDRESS=(PROTOCOL=IPC)(KEY= SND)
)
(ADDRESS =(COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)
(HOST = dbcisnd)(PORT = 1527)
)
)
STARTUP_WAIT_TIME_LISTENER = 0
CONNECT_TIMEOUT_LISTENER = 10
TRACE_LEVEL_LISTENER = OFF
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC = (SDU = 32768)(SID_NAME = SND)
(ORACLE_HOME = /oracle/SND/920_64)
)
)

And the tnsnames.ora:

SND.WORLD=
(DESCRIPTION = (SDU = 32768)
(ADDRESS_LIST =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)
(HOST = dbcisnd)(PORT = 1527)
)
)
(CONNECT_DATA = (SID = SND)(GLOBAL_NAME = SND.WORLD)
)
)

I change them to:
listener.ora
LISTENER =
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=IPC)(KEY= SND.WORLD))
(ADDRESS=(PROTOCOL=IPC)(KEY= SND))
(ADDRESS =(COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)
(HOST = dbcisnd)(PORT = 1527))
(ADDRESS = (PROTOCOL=TCP)(HOST=sapude)(PORT-1527)
)
STARTUP_WAIT_TIME_LISTENER = 0
CONNECT_TIMEOUT_LISTENER = 10
TRACE_LEVEL_LISTENER = OFF
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC = (SDU = 32768)(SID_NAME = SND)
(ORACLE_HOME = /oracle/SND/920_64)
)
)

And the tnsnames.ora:
SND.WORLD=
(DESCRIPTION = (SDU = 32768)
(ADDRESS_LIST =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)
(HOST = dbcisnd)(PORT = 1527))
)
(CONNECT_DATA = (SID = SND)(GLOBAL_NAME = SND.WORLD))
)
SSND.WORLD=
(DESCRIPTION = (SDU = 32768)
(ADDRESS_LIST =
(ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)
(HOST = sapude)(PORT = 1527))
)
(CONNECT_DATA = (SID = SND)(GLOBAL_NAME = SND.WORLD))
)

The listener on the primary (sapsnd/SND) and the failover server (sapude/SND) don't respond to tnsping anymore....

Do you have a working example of the files?

Got it to work. All it took was another set of eyes. I was missing a ")".
