when setting up data guard, if the primary clustered database is already in archive log mode, is there a need to restart both cluster instances when we update the spfile parameters for data guard ? or we can simply add the data guard parameters to the spfile while both cluster instances are online ?
View 4 RepliesI have a small problem with creating the SPFILE,
These are the commands i had issued :-
1. startup nomount
2. create SPFILE from PFILE ;
Then i got an error :-
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file 'C:ORACLEORA92DATABASEINITORCL.ORA'
Ever since this happened i am unable to connect to ORACLE under any schema !
I get the following error : -
SQL> conn scott/tiger
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Warning: You are no longer connected to ORACLE.
WHY DOES THIS HAPPEN AND HOW CAN I OVERCOME IT ?
I am going to change some parameters on primary database (db cache, java pool etc.). I am not sure, if the changes are automaticallly propagated to standby or if I have to make the changes manually on stanby site too? I couldn't find clear answer in documentation. how parameter changes work in dg physical configuration?

We are planning to create physical standby database for 4-node RAC primary to a 4-node RAC standby using Active database duplicate with ASM and OMF
1. while using active database duplicate, do we need to set cluster_database=FALSE in spfile clause and create standby,next change it back to TRUE at standby. Or we don't need to touch it. And also do we need to include instance_number parameter
2. We are using OMF, can we use log_file_name_convert parameter in spfile clause of duplicate. Documentation says log_file_name_convert cannot be used if standby is going to have OMF. Because we have 5 groups for each thread, which are on 5 different disk groups. When standby is created all the logs are created in only one disk group pointed by db_create_online_file_dest_1.
3. To enable force logging at primary do we need to shutdown the database?
I am trying to create standby database on second machine ie. not on my machine. For this i have made added the required parameters in the pfile of the primary database but when I am trying to startup the database using the new pfile I am receiving some errors.
SQL> shutdown immediate
Database closed.

i want to update a table passing the parameters and the updating the table according to it

I have to check some parameter values for an OID tuning I do not have sys access, I have only schema user access
Now how do I see the values of SGA_TARGET, db_cache_size etc parameter
I manage to see these var in init.ora file under /dbs folder but there are 2-3 spfile also having containing these attributes, not sure which reflect the actual.
Also can I alter also these value via schema user or do I need SYS access?
We have physical data guard configured version (10.2.0.4). We are in need to upgrade primary & standby database to 11G R2. Can we perform rolling upgrade.
View 3 Replies View RelatedI need to use funtion optional parameters to construct an update statement in the funtion body. I have two scenarios, either both parameters are not null or the 2nd is null. Do I have to use

ELSE
update using both param1 and param2

or is there a shortcut to do this?
Controlling User Access to Tables in a Logical Standby Database can be controlled using the following command:

I want to change dbname,sid,data/control file locations in operational dataguard setup i plan to follow as below
1)shutdown primary and standby (stop managed recovery)
2)change db name in init.ora of primary and standby change database name control file location
3)create control file for primary from trace(script) make changes for db name and file locations
4)mount and open primary database
5)create standby control file
6) transfer standby control file to standby
7) mount stand by database and start manage recovery
If this steps will error free do i need to follow any thing additional to this or what is other best way for this or its not possible at all

Statspack has been configured for Active Dataguard on Primary database.We got an spike of Buffer busy waits for about 5 min in Active Dataguard, this was causing worse Application SQL's response time during this 5 min window.Below is what i got from statspack report for one hour

Why there could sudden spike of demand on UNDO data in Active Data Guard ?
I am working in a bank as an system consultant, i have a SAN Storage Area and oracle as below.
SAN 1
This interface includes the DATA FILES of the oracle tablespace
SAN 2
SAN1 Mirrors the DATA FILES of the oracle tablespace to SAN 2
1. Can i rely on real time data recovery from SAN2 ?
2. if SAN1 (Data Files are currupted) will the SAN2 Data Files will be currupted as well.
3. If the SAN2 is currupted then what Oracle Features can be used to have uncurrupted data.
i did everything writen but when i do *SQL>alter database recover managed standby database disconnect from session;*
i go and look in the standby database AlertLog file ,and thats whats writen

strange thing that it realises the primary database in drive F and it goes to it but i dont understand what could be the reason of this ,although im doing this command while primary database is shutdown!
I configure logical standby online .when I execute dbms_logstdby.buid,first
SQL> EXECUTE DBMS_LOGSTDBY.BUILD;
it was blcoked by other sesson,then i kill the holding session,but no work.then i cancel this step and execute it again . the error is

I need to know how to modify the spfile - I know how to create it from scratch (from pfile to spfile), but need to modify an existing spfile.
View 3 Replies View RelatedSuppose my Prod Database is up and accidentally my pfile deleted. what will happen to my prod database whether it wil fail the instance or any error . as per concept that i know pfile accessed when we nomount the database for initialization of database.(11g)
in case of SPFILE
Suppose my spfile deleted and previously my database was in up condition. what will happen to my instance if i am working in a OLTP/DSS environment.(i dont have backup also how to recover and work in 11g if instance failed)
How (or having a script) to get, in PL/SQL, the parameters that have been given on a Data Pump command (export or import): mode (easy), tables/schemas list, exclude/include values and so on?
10.2 (preferred) or 11.2 as you want.
Our organization has recently decided to go for storage metro cluster solution for disaster recovery. In a Data guard environment, we normally calculate how much archive log is generating and based on that value we calculate the required bandwidth.
For storage metro cluster, we need to find how much block is changing in our primary database, and the same rate of change would apply on DR cluster. Now, i need to give the assumption how much changing is happening in my system. How to calculate the change.

Problem Description: Cloning from Source instance A to target instance B and both are in ASM instances.RMAN backup in source instance A is completed, which has spfile configured in non-default location in ASM for example,see belowASMCMD
[+ASMDG003/TEST1 > ls -ltType Redund Striped Time Sys Name Y TEMPFILE/ Y ONLINELOG/ Y DATAFILE/ Y CONTROLFILE/ N spfiletest1.ora => +ASMDG003/TEST1/PARAMETERFILE/SPFILE.747.856347
Also, there is no SPFILE in $ORACLE_HOME/dbs for the TEST1 source instance. INITTEST1.ora file has the following entry:
cat INITTEST1. oraspfile='+ ASMD G003 /TEST1/spfileTEST1.ora'
Question: In the target instance to be cloned from RMAN backup fro source instance TEST1, on performing ' restore spfile from autobackup 'location';Will the spfile be restored in $ORACLE_HOME/dbs in the target instance TEST2?
whenever i tried to create spfile from pfile i got this error...oracle not available and shared memory realme does not exist.

I've pasted some of the results of an RMAN backup that I ran. It says that it's backing up both the Control File and the SPFILE, but it appears that only one file is being created. Is this correct? How does this work? Are both files combined into the C-3843121877-20120619-00 file?

Also, regarding the below configuration of RMAN - I can change this directory to whatever I want, correct? In other words, is it just the directory where I am putting the backup?
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'C:ORACLEPRODUCT10.2.0DATABASESNCFPLDG.ORA'; # default
What is correct way to move the default oracle spfile to ASM diskgroup so i can successfully bring up the instance . After bring up the instance , it should point to ASM diskgroup. My oracle database 11.2.0.3 is siting on sun solaris 64 Bit.
