How to setup Data guard for SAP database?

Can someone please tell me how to setup data guard for SAP databases?
Thanks,
Abhi

Hi Abhi,
have a look at OSS 105047 - Support for Oracle functions in the SAP environment you find this under
14
Oracle Data Guard
You can use "Physical Standby".
You cannot use "Logical Standby".
You are allowed to use Fast Start Failover (FSFO) but SAP Support is not provided.
You can use Data Guard Broker.
You can use Maximum Performance Mode, Maximum Availability Mode and Maximum Protection Mode.
In the case of Maximum Availability and Maximum Protection, you must pay particular attention to a fast network connection in order to avoid performance problems.
Maximum Protection causes the primary database to terminate if problems occur in the standby database.
And here you find on Oracle white paper from 2010 http://www.oracle.com/us/solutions/sap/wp-ora4sap-dataguard11g-303811.pdf
Perhaps some SAP user have answers for you http://scn.sap.com/community/oracle/content?query=guard

Data guard in sap

Hello Gurus
I need to implement data guard in sap on windows.
i have configured data guard earlier on windows successfully but with cold backup.Now as its sap i have some doubts.
If someone has did same kind or possess idea.PLEASE HELP
Details--SAP ERP6.0EHP6
ORACLE 11.2.0.3
WINDOWS 2008 EE R2 64BIT
db size 1.2TB
1)can i take online backup WITH BR TOOL and store it on DR as my client used to take it and says that we can use it or i need rman backup so as to create DR.
2)Is DR implementation in SAP is same as normal.Do i need to follow the same kind of approach as i did in normal setup or its different.
Regards

1)can i take online backup WITH BR TOOL and store it on DR as my client used to take it and says that we can use it or i need rman backup so as to create DR.
indeed BR tools are supported even on standby database also, In detail check this link.

Implementation is same and there are no changes, But you can't use of ADG(Active Data Guard)

Oracle Data Guard, SAP instances not coming up after switchover

Dear Experts,
We have implemented Dataguard, Uisng Maximum performance with real time apply (redo log apply). Redo logs are apply from primary to standby perfectly. And the SAP Instances are up and running, when we create a user in primary its reflecting in standby server.
When i do the the switchover from primary <--> standby. There is no communication between R3 and database. I have refered the Note 400241, have not got the solution. I changed the password of the OPS$ user uisng brtools utility. Still getting the r3trans return code 0012.

Hi Nisar,
We would like to implement the data guard , the system landscapes are also similar to your site. Can u pls give me the documentation which explains step by step configuration. We are not able to activate oracle enterprise manager where the configuration is slightly simple. Is it possible to have the primary and standy database with same db_name?. Pls help to proceed further.

Data guard sid

Dear Gurus
I need to implemement data guard in sap.client is asking that on standby its required that sid be same as primary because sap uses it.
So is it possible to configure data guard with same sid's on primary and standby.
also as i keep sid same the directory structure would be same in that case like
on primary --E:\oracle\db\ppm
on standby- E:\oracle\db\ppm
so no need to use parameter db_file_name_convert and log_file_name_convert
so would it be a fine configuration of data guard
OS--Windows2008

Data guard difference in primary and standby OS.

Dear All,
We are planning to setup a data guard in our landscape. But my question what are the prerequisites should be consider before getting in to that.
Like my environment -
1. The primary database is running with Red hat Linux 5 - IBM 64 bit and the standby database is Redhat Linux 2.1 IBM 32 bit system.
2. The primary database is running with Red hat Linux 5 - IBM 64 bit with oracle 8.1.7.4 and the standby database is
Linux 2.1 IBM 32 bit system with oracle 10g.
Is the above thing is possible? or we should maintain the same OS / DB combination in the data guard setup.
I am following the below link.
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/standby.htm#i72053
If anyone have thoughts on this please do advice me.
Regards
Vijay

Please explain to us what exactly you want to do with the standby database?
According to note 105047 - Support for Oracle functions in the SAP environment
12. Data Guard
You can use "Physical Standby", but Oracle provides support (not SAP).
You cannot use "Logical Standby"
So in short, no a data guard configuration with Red hat Linux 5 - IBM 64 bit with oracle 8.1.7.4 to Linux 2.1 IBM 32 bit system with oracle 10g is NOT possible.

DATA GUARD IN ACTIVE PASSIVE OS CLUSTER WINDOWS

Hello Gurus
I am setting up data guard in sap on windows with active passive OS clustering.
Please clear below 3 confusions.
1)I have same database name and sid of standby database as primary.Now to have different service i am just using it in setting parameters and tns_alias like
Listener file for primary and standby same as sid same
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=PROD)
(ORACLE_HOME=/oracle/product/11.2.0)
(SID_NAME=PROD)
tNSNAMES adding entry on primary as
PROD2
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=dev-db2)
(port=1521)
(connect_data=
(service_name=prod2
server=dedicated)))
tnsnames added entry on standby of primary
PROD
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=dev-db2)
(port=1521)
(connect_data=
(service_name=prod
server=dedicated)))
---->in parameter i am using service for standby as
alter system set log_archive_dest_2='service=PROD2 async valid_for=(online_logfile,primary_role) db_unique_name=prod2;
**But i have am not creating any service as such.Will THIS WORK and alright.
as i am having confusion that my SID is same so how service be differentiated.am i doing right way.
2)as my primary database having 2 node in OS cluster so like node1 having ip 192.68.2.22 node 2 ip 192.68.2.23..They are in active passive clusten.the datafiles and other oracle files can be shifted to any node as per requirement.So they are using a virtual ip 192.68.2.20.. Now i need to create standby for this primary....standby ip is 192.68.2.40
So in tnsnames i am giving all ips the virtual ip 192.68.2.20 and host ips of both nodes on standby tnsnames and on primary adding entry of standby ip 192.68.2.40.Means i am doing entries of virtual ip and host of node1 and node2.
So i am able to ping the virtual ip from standby but not able to ping 192.68.2.22 and 192.68.2.23.
So is it fine .Would i be able to create standby database as only virtual will be needed or i am going on wrong path.
3)Can i just create the standby database by using duplicate command without taking backup in 11g.(means without physical copy of data files etc from primary to standby)
likewise
On the primary server, connect to Primary database(ORCL) as target and standby database(ORCL_DTGD) as auxiliary.
$ rman target sys/sys@ORCL auxiliary sys/sys@ORCL_DTGD
RMAN>DUPLICATE TARGET DATABASE FOR STANDBY FROM ACTIVE DATABASE DORECOVER
SPFILE SET DB_UNIQUE_NAME='ORCL_DTGD' SET LOG_ARCHIVE_DEST_2='service=ORCL LGWR SYNC REGISTER VALID_FOR=(online_logfile,primary_role)' Set STANDBY_FILE_MANAGEMENT='AUTO' SET FAL_SERVER='ORCL' SET FAL_CLIENT='ORCL_DTGD' SET CONTROL_FILES='/data/oracle/app/oracle/oradata/ORCL/control01.ctl’,'/data/oracle/app/oracle/fast_recovery_area/ORCL/control02.ctl’ NOFILENAMECHECK;
after configuring tns,listener etc
Regards
thanks for ur time..please reply as i am really looking for ur great ideas and need them.

For Question 1:
The SERVICE attribute, which is a mandatory attribute for a redo transport
destination, must be the first attribute specified in the attribute list. The SERVICE
attribute is used to specify the Oracle Net service name used to connect to the redo
transport destination. The service name must be resolvable through an Oracle Net
naming method to an Oracle Net connect descriptor that matches the Oracle Net
listener(s) at the redo transport destination.
Source - 6.2.2 Configuring an Oracle Database to Send Redo Data
Concepts and Administration 11g Release 2 (11.2) E10700-02
For Question 2:
I would DNS if possible. If you cannot see IP's you can add them the the HOSTs file on most OS's as a work around.
Not sure what you are trying to do exactly.
For Question 3:
Yes.
Duplicate for Standby using active duplicate.

Parameters need to configure Data Guard with Data Guard Broker

Hi gurus,
I'm following this guide http://www.oracle.com/us/solutions/sap/wp-ora4sap-dataguard11g-303811.pdf, but it isn't clarify what parameters we need to set to get the service up.
I noticed that we can setting up for two ways, either Oracle Enterprise Manager or Data Guard Broker. Do we need to configure the same parameters to OEM and after to activate the DGMGRL?
Can you help me?

View Log in Data Guard

In dataguard when i check view log(OBJECT-Viewlog) it return
"Data Guard Remote Process Startup Fail"?
Regards

hi there,
What's your question and you need to provide the version and the type of standby db too?

Data Guard adding new data files to a tablespace.

In the past, if you were manually updating an Oracle physical standby database there were issues with adding a data file to a tablespace. It was suggested that the data file should be created small and then the small physical file copied to the standby database. Once the small data file was in place it would be resized on the primary database then the repication would change the size on the standby.
My question is, does Data Guard take care of this automaticlly for a physical standby? I can't find any specific reference on how it handles a new datafile.

Never mind, I found the answer.
STANDBY_FILE_MANAGEMENT=auto
Set on the standby database will create the datafiles.

Problem with logminer in Data Guard configuration

Hi all,
I experience strange problem with applying of the logs in DataGuard configuration on the logical standby database side.
I've set up the configuration step by step as it is described in documentation (Oracle Data Guard Concepts and Administration, chapter 4).
Everything went fine until I issued
ALTER DATABASE START LOGICAL STANDBY APPLY;
I saw that log applying process was started by checking the output of
SELECT NAME, VALUE FROM V$LOGSTDBY_STATS WHERE NAME = 'coordinator state';
and
SELECT TYPE, HIGH_SCN, STATUS FROM V$LOGSTDBY;
but in few minutes it stoped and quering DBA_LOGSTDBY_EVENTS I saw the following records:
ORA-16111: log mining and apply setting up
ORA-01332: internal Logminer Dictionary error
Alert log says the following:
LOGSTDBY event: ORA-01332: internal Logminer Dictionary error
Wed Jan 21 16:57:57 2004
Errors in file /opt/oracle/admin/whouse/bdump/whouse_lsp0_5817.trc:
ORA-01332: internal Logminer Dictionary error
Here is the end of the whouse_lsp0_5817.trc
error 1332 detected in background process
OPIRIP: Uncaught error 447. Error stack:
ORA-00447: fatal error in background process
ORA-01332: internal Logminer Dictionary error
But the most useful info I found in one more trace file (whouse_p001_5821.trc):
krvxmrs: Leaving by exception: 604
ORA-00604: error occurred at recursive SQL level 1
ORA-01031: insufficient privileges
ORA-06512: at "SYS.LOGMNR_KRVRDREPDICT3", line 68
ORA-06512: at line 1
Seems that somewhere the correct privileges were not given or smth like this. By the way I was doing all the operations under SYS account (as SYSDBA).
Could smb give me a clue where could be my mistake or what was done in the wrong way?
Thank you in advance.

Data guard synchronization after link down b/w primary and physical standby

Hi All,
I have configured data guard on oracle 11gr2 db. Normally switchover between my primary and physical standby happens smoothly and the Apply lag would be zero. Recently We had to test a scenario when the network link between Primary and Physical standby is completely down and Physical standby is isolated completely for more than half an hour.
When we brought up the link every thing worked smoothly but apply lag started increasing from 0 to around 3 hrs. And then it started reducing to 0. Currently Apply lag and transport lag shows 0.
But is this normal behaviour of oracle data guard that when the link between primary and physical standby is completely down, It requires 3-4 hrs for resynchronization ??? Even when during isolation, there were very few transactions happend on primary database ??
Are there any documents available for this scenario??
Thanks

Hi, after the link is up, if there were some transactions and produced archive logs it's normal to take some time for resync. To check if 3-4 hours is normal or not, you can repeat the scenario and this time check
- how many archivelogs does primary produce in this period.
- after the link is up, does archivelog transfer immediately starts from primary to standby? Is primary able to send these archivelogs parallel?
- Is there anything wrong with the apply process?
check primary & standby alert log files, and run this query on standby to check the transport and apply processes:
SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS FROM V$MANAGED_STANDBY;
regards

Creating a Crystal Report from a non-SAP data base

I have the following scenario
server1\myDataBase
server1\SAP\sapDataBases
in sapDataBases I have about 30 company databases. I am trying to create a report, that gets informatino from a table/view/SP from server1\myDataBase, when I try to PREVIEW or SAVE such report on SAP Business One, I always get errors as
I understand that this eerror means taht I can't invoke the data from out of SAP; it needs to be inside SAP (at least the SP, incoking some other data bases and stuff..)
Some bodies have told me that it is beacuase I can only create a report from a table/view/sp that resides in the running/currently SAP company database. Is this right?
Also, If this is the case, this means that If I have an SP taht I use for a crystal report, and 30 companies, I have to create such SP in the 30 companies?
This is my software details:
SQL Server 2012
SAP Business One 9 PL 11
SAP BusinessObjects Crystal Reports 2013 Support Pack 2 version 14.1.2.1121
What I want to do is to create a non-SAP data base to create all the SPs/Views for reports, to centralize it, and the just create one reporte and do the 30-imports in each company database, without the need of creating such sps/views in each company-database. Is this possible?
Thanks

Moved to Integration Kit forum.
The people in this forum will know more about the data structure than the CR Design forum which typically doesn't know much about the SAP Data sources Structure.
