RAC 11GR2 + expdp/impdp

Hi all,
I have installed Rac 11gr2 on linux RedHat.
I have to migrate data from a 10.1 database to the 11.2 database.
Could you tell me which version of expdp and impdp should i use?
Thanks.

You use the 10g datapump expdp on the 10g DB (source) and the 11g impdp on the 11g DB (target).
Kind regards

EXP/IMP..of table having LOB column to export and import using expdp/impdp

we have one table in that having colum LOB now this table LOB size is approx 550GB.
as per our knowldge LOB space can not be resused.so we have alrady rasied SR on that
we are come to clusion that we need to take backup of this table then truncate this table and then start import
we need help on bekow ponts.
1)we are taking backup with expdp using parellal parameter=4 this backup will complete sussessfully? any other parameter need to keep in expdp while takig backup.
2)once truncate done,does import will complete successfully..?
any SGA PGA or undo tablespace size or undo retention we need to increase.. to completer susecfully import? because its production Critical database?
current SGA 2GB
PGA 398MB
undo retention 1800
undo tbs 6GB
please any one give suggestion to perform activity without error...also suggest parameter need to keep during expdp/impdp
thanks an advance.

Hi,
From my experience be prepared for a long outage to do this - expdp is pretty quick at getting lobs out but very slow at getting them back in again - a lot of the speed optimizations that may datapump so excellent for normal objects are not available for lobs. You really need to test this somewhere first - can you not expdp from live and load into some test area - you don't need the whole database just the table/lob in question. You don;t want to find out after you truncate the table that its going to take 3 days to import back in....
You might want to consider DBMS_REDEFINITION instead?
Here you precreate a temporary table (with same definitiion as the existing one), load the data into it from the existing table and then do a dictionary switch to swap them over - giving you minimal downtime. I think this should work fine with LOBS at 10g but you should do some research and see if it works fine. You'll need a lot of extra tablespace (temporarily) for this approach though.

Log file's format in expdp\impdp

Hi all,
I need to set log file format for expdp\impdp utility. I have this format for my dump file - filename=<name>%U.dmp which generates unique names for dump files. How can i generate unique names for log files? It'd better if dump file name and log file names will be the same.
Regards,
rustam_tj

Hi Srini, thanks for advice.
I read doc which you suggest me. The only thing which i found there is:
Log files and SQL files overwrite previously existing files.
So i cant keep previos log files?
My OS is HP-UX (11.3) and database version is 10.2.0.4

Expdp/impdp :: Constraints in Parent child relationship

Hi ,
I have one table parent1 and tables child1, child2 and chld3 have foreign key created on this parent1.
Now I want to do some deletion on parent1. But since number of records are very high on parent1 , we are going with expdp / impdp with querry option.
I have taken query level expdp on parent1. Now I dropped parent1 with cascade constraints option and all the foreign keys created by child1 ,2 and 3 which references parent1 are automatically dropped.
Now If i fire the impdp for the query level dump file , will these foreign key constraints will get created automatically on child1 ,2 and 3 or I need to manually re-create it ??
Regards,
Anu

Hi,
The FK's will not be in the dumpfile - see the example code below where i generate a sqlfile following pretty much the process you would have done. THis is because the FK is part of the DDL for the child table not the parent.

System generated Index names different on target database after expdp/impdp

After performing expdp/impdp to move data from one database (A) to another (B), the system name generated indexes has different names on the target database, which caused a major issue with GoldenGate. Could anyone provide any tricks on how to perform the expdp/impdp and have the same system index name generated to be the same on both source and target?
Thanks in advance.
JL

While I do not agree with Sb choice of wording his solution is correct. I suggest you drop and recreate the objects using explicit naming then you will get the same names on the target database after import for constraints, indexes, and FK's.
A detailed description of the problem this caused with Golden Gate would be interesting. The full Oracle and Golden Gate versions is use might also be important to the solution, if one exists other than explicitl naming.

ASM pfile lost in Oracle RAC 11gr2

Hello Gurus,
I am new to Oracle RAC 11gr2 and facing some issues. our spfile/pfile for asm instance is lost and I am not able to startup the asm instance.
Environment is as below:

Hi,
Do we need to Set variable ORACLE_HOME properly (Grid Home) while starting RDBMS instance?
e.g ORACLE_HOME=/u01/app/11.2.0/grid*I recommend you set ORACLE_HOME properly for each Oracle Installation when you use SQLPLUS.
i.e: cat /etc/oratab
orcl:/u01/app/oracle/product/11.2.0/db_1
db10g:/u01/app/oracle/product/10.2.0/db_1
+ASM1:/u01/app/11.2.0/gridAlso you can startup/shutdown our database with SQLPLUS using ORACLE NET*, but it must be configured properly.
My recommendation <s>is always</s> use SRVCTL and CRSCTL to manage to your environment. Track all the process of initialization processes through the logs using ADRCI utility (only 11.1 or later).
When use SRVCTL or CRSCTL to manage I recomend you use (GRID HOME).

2° - Make backup of all archivelog using RMAN and option delete input (i.e backup archivelog delete all input;)
3° - If this database is for TEST ONLY and you not need backup or recovery of then you can delete all archivelog using RMAN (i.e delete archivelog all;)
I recommend you create routine of backups of the database and archivelog to prevent this area becomes exhausted.
If you need the database in archivelog but it is only to test then create routine to delete archivelogs periodically.
If you dont need the database in archivelog, then just disable it.

How to migrate DB from single node 10gR2 to RAC 11gR2 on diff platform?

How to migrate DB from single node 10gR2 to RAC 11gR2 on different platform with possible minimum downtime? We have a situation of upgrade/migrate oracle 10gR2 single instance DB to 2-node RAC 11gR. The source OS is Solaris 10 on SPARC and the target OS is Linux (the target servers could be changed to Solaris 11 x86 if needed). What is the best solution on that?
Thanks,

Technically, can do the following for upgrading and migration?
1. Create 11gR2 oracle home on the same server and upgrade the database from 10gR2 to 11gR2 by running conversion (2 hour down time?)
2. Set up Heterogeneous Primary and Physical Standbys by RMAN. The standby is the RAC with ASM. No need down time. (from Solaris Space to Linux - this may be a problem)
3. At the cutoff time, activate the standby DB from the RAC ASM.
If feasible, do we have some detail guild line for each step?

Best Practice for monitoring RAC 11gR2

Hi,
I have RAC 11gR2+ASM on two nodes.
I would like to get your advice what are the most critical things i should monitor - Regarding RAC COMPONENCTS
Thanks

Hi,
here i am mentioning some basic monitoring
1)interconnect switch is working properly or not(private network)
2) check which instances are running on which nodes
3) check if ASM,listeners,nodeapps,gsd,vip..... are running or not.
Each instance carrying planned load (balanced?).
– Shared storage access is equal.
– Interconnect Load
-Latency
– High CPU usage - Oracle processes getting enough resources.?
Thanks

Using ZFS for Oracle RAC 11gR2 binaries

Hi,
We have following scenario,
Two Node Cluster: Oracle RAC 11Gr2 with Clusterware on Solaris 10
We want to keep Oracle & Clusterware binaries on ZFS mirror file system on each node locally and for Data files, FRA, Voting disks & OCR on shared SAN using ASM.
My question, is the above scenario certified by Oracle or can we keep Oracle binaries on ZFS...?
Will appreciate your input.
Thanks

Well my confusion started after reading this doc on oracle support:
Certification of Zeta File System (Zfs) On Solaris 10 for Oracle RDBMS [ID 403202.1]
"Oracle database 10gR2 (10.2.0.3 and higher patches), 11gR1 (11.1.0.6 and higher patches) and 11gR2 (11.2.0.1 and higher patches) are certified with Solaris 10 ZFS on Sparc 64-bit and Solaris x84-64. See Solaris ZFS_Best_Practices_Guide. This is for single instance ONLY. ZFS is currently not applicable to RAC and not Certified to use it as a shared filesystem."

Oracle rac 11gr2 + sga

Hi all,
I have a 2 nodes rac 11GR2 on linux redhat with 12Go RAM each one.
Since 15 days, a dba add more memory on each node (+ 24Go RAM) and modify SGA like :
On each node :
create a pfile from spfile, modify memory_max_target on pfile (from 7Go to 8Go), and restart each instance from this pfile.
Now, the problem are :
Each node consume 36Go of 36Go RAM,
The parameter spfile is empty (show parameter spfile).
Do you an idea why all RAM is consumed on each node ?
Thanks.

Problem 1: Why is that a problem? How did you establish 36 Gb is used. The Unix tools are notoriously for providing incorrect information as the SGA is accounted for in every process.
Problem 2: Evidently the "DBA' used an incorrect procedure to change these parameters, and didn't convert the pfile to spfile again, and started using the 'startup pfile' command.
The action plan for this twofold
- educate the "DBA' or don't hire him anymore
- use the create spfile from pfile command, and restart the database.

I tried: srvctl start instance -d orcl -i orcl1 or srvctl start instance -d orcl -i orcl2
but the same error, where is the High Availibilty in that case, the redo log file group_1 is for thread 1 only. SHould not be able to start Instance 2?

Steps to stop / start CRS & ASM in RAC 11gr2

Hello Gurus,
Environment is as below:
RAC 2 nodes
Oracle RAC 11gr2
Enterprise Linux Server release 5.5 (Carthage)
I am new to Oracle RAC 11gr2 and facing some issues while stop / start crs & asm.
We want to reboot both nodes and for that I have done following steps.
1. srvctl stop database -d <db name> -- from one node
Databse is down now.2. srvctl stop nodeapps -n <hostname> -- from both nodes
services are down now.3. Now I want to stop asm
$ export ORACLE_HOME=/u01/app/11.2.0/grid ( Grid Home)
$ srvctl stop asm - This is not stopping ASM instance.
4. crsctl stop crs -- this is also not working.
I would appreciate if you please give me full steps.
Thanks and Regards,

In 11gr2, gsd remains offline. When I had checked with metalink, they said that it is fine.
In 11gr2 you can stop all resouces as below
<CRS_HOME>/bin/crsctl stop has
or you can stop in the following sequence
stop or relocate service using srvctl
stop instnace using srvctl
stop asm using srvctl
stop nodeapps using srvctl
stop cluster resources as root - <CRS_HOME>/bin/crsctl stop has
To start
<CRS_HOME>/bin/crsctl start has - it should bring all resources automatically
verify the services status and start or relocate it back.
