Best oracle RAC book

can any one suggest me a best oracle book beyond documentation...
sure,
we can understand all the concepts through the documentation. have gone through clusterware administration and rac administration twice.
can any one tell me best book for troubleshooting basic oracle rac issues. and tuning the oracle rac. wait events etc.

Julian Dyke RAC books are considered to be among the best RAC available books:
Pro Oracle Database 10g Rac on Linux: Installation, Administration And Performance by Julian Dyke, S Shaw
Pro Oracle Database 11g Rac on Linux by Steve Shaw,Julian Dyke,Martin Bach
However these books are not specialized in RAC troubleshooting. For RAC 10g a very good RAC wait event documentation can be found in Oracle wait interface: a practical guide to performance diagnostics & tuning by Richmond Shee,Kirtikumar Deshpande,K. Gopalakrishnan.

Any Oracle best practice/standards for inter-DataCente links for Oracle RAC

Hello Oracle Experts,
Am working for a customer to set up Oracle RAC architecture hosting SAP/Non-SAP applications per SLA levels(MC/BC/Standard) specs. Currently my network team needs calculation to arrive at whether we will go for a (1), (2) or (3) 10Gig links for inter DC (Data-Center) for Oracle RAC.. below is additional background:
•     Porting all client SAP/Non-SAP Oracle databases to new 2 data-centers.
•     There will be 10 blades (4x BL680s and 6x BL460s) in each DC (can scale-up/out later on).
•     Clusters architecture to support Extended/Stretched RAC cluster feature
•     Clusters 2-node each(1-datacenter1, 1-datacenter2) and nodes distributed across 2 x c7000 such that no cluster has more than one node in an enclosure.
•     Each node will have - 4 NIC ports ( 2 x public and 2 x private) , 2 dual-port HBA
•     Oracle ASM/ACFS (ASM Cluster File System), Voting Disk, OCR and Database files
•     the versions are Oracle 11g RAC, Oracle 10g RAC and Oracle 9i (for DataGuard/Standby) on RHEL 6 on Proliant Blades (x86) + BladeMatrix
My network colleagues considering using DWDM across the 2 DCs(given the lesser cost?). Am still looking around if there are any Oracle/industry-best practices around this and having a calculation to support that..
Many Thanks in advance..

Abhijit

Hi ,
There are no specific set of steps / practices for batch loading contents to ucm . It would be very much dependent on how many contents does the user have to load to UCM and how well the server is configured in terms of performance .
You can get more details from the following documentation link : http://docs.oracle.com/cd/E21043_01/doc.1111/e10792/c02_settings009.htm

Oracle RAC /apps best practice

New to RAC and trying to set up the filesystems according to best practice. For the /apps mountpoint (for oracle binaries etc.) we have made it seperate to each server, with the thought that 'rolling' oracle upgrades could be done rather than a shared storage to all servers in the cluster. Unfortunately by having it on the SAN it causes configuration issues when then presenting shared storage for data to the cluster.
Do most (best practice) RAC clusters have local (on board) storage for the /apps oracle binaries rather than SAN presented storage?
Thanks.

Oracle RAC 11G - Service configuration

Hi,
I have been reading a lot of documentation regarding oracle services and I have an ok understanding of how they work. However, I have a general question regarding configuring services using Oracle RAC. For instance, if I have a 2 node oracle 11GR2 RAC on a Linux Redhat server. I have an application that connects to a service I have created. I create the service as follows.
srvctl add service -d ORCL_RAC -s APP_SERVICE -r ORCL_RAC1,ORCL_RAC2
The tnsnames contains:
APP_OLTP =
(DESCRIPTION =
(LOAD_BALANCE = ON)
(FAILOVER = ON)
(ADDRESS = (PROTOCOL = TCP)(HOST = server01)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = server02)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = APP_SERVICE)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 20)
(DELAY = 1)
My questions are as follows:
1) When I do a 'srvctl status service -d ORCL_RAC', should I see the service running on both nodes of the RAC? Or does it run only one node, then it will fail over to the other when needed?
2) If I have a RAC environment where I see two services created (RAC_SRV1 and RAC_SRV2). I see that RAC_SRV1 is only running on node1 and RAC_SRV2 is only running on node2. There are two applications sharing the same database, one application is using RAC_SRV1 and the other application is using RAC_SRV2. Am I correct in thinking that there is no failover available here? If node1 goes down, the application connecting to RAC_SRV1 will not be able to connect to node2 right?
3) In the case of the scenario in question 2 above, would it be best practise to simply create one service and have both applications connecting to the one service? Could I configure the one service to point connections from one application to node1 and connections from the other application to node2?

1) When I do a 'srvctl status service -d ORCL_RAC', should I see the service running on both nodes of the RAC? Or does it run only one node, then it will fail over to the other when needed?you can see its running on both nodes.
use option -a in srvctl ( A list of available instances to which the service fails over when the database is administrator managed.)

RCA for Oracle RAC Performance Issue

Hi DBAs,
I have setup a 2 node Oracle RAC 10.2.0.3 on Linux 4.5 (64 bit) with 16 GB memory and 4 dual core CPUs each. The database is serving a web application but unfortunately the system is at its knees. The performance is terrible. The storage is a EMC SAN but ASM is not implemented with a fear to further degrade the performance or not to complicate the system further.
I am seeking the expert advises from some GURUs from this forums to formulate the action plan to do the root cause analysis to the system and database. Please advise me what tools I can use to gather the information about the Root Cause. AWR Report is not very helpful. The system stats with top, vmstat, iostat only show the high resource usage but difficult to find the reason. OEM has configured and very frequently report all kind of high wait events.
How I can use effectively find Network bottle necks (netstat command which need to be really helpful to understand).
How I can see the system I/O (iostats) which can provide me some useful information. I don't understand what sould be the baseline or optimal values to compare the I/O activities.
I am seeking help and advised to diagnose the issue. I also want to represent this issue as a case study.
Thanks

First of all, RAC is mainly suited for OLTP applications.
Secondly, if your application is unscalable (it doesn't use bind variables and no SQL statements have been tuned and/or it has been ported from Sukkelserver 200<whatever>) running it against RAC will make things worse.
Thirdly: RAC uses a chatty Interconnect. If you didn't configure the Interconnect properly,and/or are using slow Network cards (1 Gb is mandatory), and/or you are not using a 9k MTU on your 1 Gb NIC, this again will make things worse.
You can't install RAC 'out of the box'. It won't perform! PERIOD.
Fourthly: you might suffer from your 'application' connecting and disconnecting for every individual SQL statement and/or commit every individual INSERT or UPDATE.
You need to address this.
Using ADDM and/or AWR is compulsory for analysing the problem, and/or having read Cary Millsaps book on Optimizing Oracle performance is compulsory.
You won't come anywhere without AWR and OS statistics will not provide any clue.
Because, paraphrasing William Jefferson Clinton, former president of the US of A:
It's the application, stupid.
99 out of 100 cases. Trust me. All developers I know currently are 100 percent clueless.
That said, if you can't be bothered to post the top 5 AWR events, and you aren't up to using AWR reports, maybe you should hire a consultant who can.

Upgrading Oracle RAC from 10.0.2.3 to 10.0.2.4 on HP-UX

Hi all,
I have to apply 10.0.2.4 patch to Oracle RAC that running on HP-UX system. I'm inexperienced with this subject. What is your suggestions and recommendations about this? Can you share the your own roadmap and your experience?
Regards,
Alper.

Hi Alper,
a good starting point for upgrades are the Oracle Upgrade Companions for 10gR2 and 11g - they cover best practices and behaviour changes:
Note.466181.1- 10g Upgrade Companion
Note.601807.1 - Oracle 11g Upgrade Companion

Disable Intel CPU Hyper threading in Oracle RAC environment

Dear Expert,
Does disable CPU hyper threading will have direct impact or maybe unexpected behavior to Oracle RAC database?
Actually the background of this question is we have many received packet queuing on the network layer waiting to be processed. Investigation leads to the processor utilization which shows that many processor are still in idle state or not used when the other processors are busy processing incoming request.
I have visited some oracle note like
CPU Count Consideration for Oracle Parameter Setting When Using Hyper-Threading Technology (Doc ID 289870.1)
Oracle and Hyper-Threading (Doc ID 205089.1)
Using PROCESSOR_GROUP_NAME to bind a database instance to CPUs or NUMA nodes (Doc ID 1585184.1)
These document already give useful information but i wonder if there is any possibilities risk or another consideration of disabling cpu hyper threading.
Please let me know if any other information required.
Thanks.
Best Regards,
Jolly

As far as I know it is set as cpu architecture and mobile chips don't have the option. Not 100% as I've never needed to do it.
Better bet would be to check Intel ark and forums with them I expect.

Oracle Rac 11.2.0.3 doubts

Hi experts,
Current system info:
server 1 with Redhat 6.5 and Orale ASM with SAP ECC 6 GRID 11.2.0.3 standalone installation
Target system info:
Server 1 and server 2 running RAC 11.2.0.3 with SAP ECC 6 and RedHat 6.5 GRID with cluster
We are trying to convert our current system to oracle RAC but have some doubts.
We are following "Configuration of SAP NetWeaver for Oracle Grid Infrastructure 11.2.0.2 and Oracle Real Application Clusters 11g Release 2: A Best Practices Guide" so:
On page 29 It says: "Prepare the storage location for storing the shared ORACLE_HOME directory in the cluster. The Oracle RDBMS software should be installed into an empty directory, accessible from all nodes in the cluster" Same thing for ORACLE_BASE for the RDBMS, SAP subdirectories (sapbackup, sapcheck, sapreorg, saptrace, oraarch etc.) and homedirectories for SAP users ora<SID> and <SID>adm to a shared filesystem.
1.-Can we just use NFS for sharing them? or what is the recommended software on REDHAT for doing it?
'cause on note 527843 it says:
You must store the following components in a shared file system (cluster, NFS, or ACFS) here it says we can, but down the note on section linux says:
RAC 11.2.0.3/4 (x86 & x86_64 only):
Oracle Clusterware 11.2.0.3/4 + ASM/ACFS 11.2.0.3/4 (Oracle Linux 5, Oracle Linux 6, RHEL 5, RHEL 6, SLES 10, SLES 11)
Oracle Clusterware 11.2.0.3/4 + NetApp NFS or
Oracle Clusterware 11.2.0.3/4 + EMC Celerra NFS
It does not mention just NFS.
2.-In our system test, we want to backup all oracle configuration files on file systems and then delete Oracle Grid to Install GRID with cluster option, then install RDBMS with rac option and then follow the guide, is that correct?
Regards

Hi Ramon,
1.-Can we just use NFS for sharing them? or what is the recommended software on REDHAT for doing it?

Oracle Clusterware 11.2.0.3/4 + NetApp NFS or
Oracle Clusterware 11.2.0.3/4 + EMC Celerra NFS
It does not mention just NFS.
NFS mount as suggest in SAP documentation should work. The use of ACFS always requires a special Oracle Grid Infrastructure (GI) Patch Set Update (PSU). Oracle Support Note 1369107.1 contains details about which GI PSU is required when you use ACFS with a specific RHEL update, service pack from SLES or UEK version of Oracle.
2.-In our system test, we want to backup all oracle configuration files on file systems and then delete Oracle Grid to Install GRID with cluster option, then install RDBMS with rac option and then follow the guide, is that correct?
You may perform DB backup using backup tools and then scrap the existing Grid setup. Configure RAC and then restore the backup into the new configuraiton as per SAP guidelines under
Configuration of SAP NetWeaver for Oracle Grid Infrastructure 11.2 with Oracle Real Application Clusters 11g Release 2
Hope this helps.

Does /sapmnt need in cluster file system(SAP ECC 6.0 with oracle RAC)

We are going to be installing SAP with Oracle 10.2.0.4 RAC on Linux SuSE 10 and OCFS2. The Oracle RAC documentation states:
You must store the following components in the cluster file system when you use RAC
in the SAP environment:
- Oracle Clusterware (CRS) Home
- Oracle RDBMS Home
- SAP Home (also /sapmnt)
- Voting Disks
- OCR
- Database
What I want to ask is if I really need put SAP Home(also /sapmnt) on cluster file system? I will build a two nodes oracel 10g RAC and I also have another two nodes to install SAP CI and DI. My orginial think is sapmnt is a NFS share, and mount to all four nodes(RAC node and CI/DI), and all oracle stuff was on OCFS2(only two rac nodes are OCFS), anybody can tell me if SAP Home(also /sapmnt) can be NFS mount not OCFS2, thanks.
Best regards,
Peter

Hi Peter,
I don't think you need to keep /sapmnt in ocfs2 . Reason any file system need to be in cluster is,in RAC environment, data stored in the cache of one Oracle instance to be accessed by any other instance by transferring it across the private network and preserves data integrity and cache coherency by transmitting locking and other synchronization information across cluster nodes.
AS this applies to redo files, datafiles and control files only , you should be fine with nfs mount of /sapmnt sharing across and not having ocfs2.

Solaris x86 with Oracle RAC 10g Enterprise Edition Release 10.2.0.3.0

Hello,
Maybe you can help me (new on RMAN backup) in doing this.
I have configured a single Oracle 10g database to have backup with RMAN with following steps:
1. $ mkdir $ORACLE_BASE/rman_scripts
2. $ mkdir $ORACLE_BASE/logs
3. $ mkdir $ORACLE_BASE/tracking
4. $ mkdir $ORACLE_BASE/c_backup
5. $ sqlplus sys/<password> as sysdba
6. SQL> alter system set db_recovery_file_dest_size = 50G scope=both;
7. SQL> alter system set db_recovery_file_dest='${ ORACLE_BASE}/flash_recovery_ area' scope=both;
8. SQL> alter system set log_archive_dest_10='location= use_db_recovery_file_dest';
9. SQL> shutdown immediate
10. SQL> startup nomount
11. SQL> alter database archivelog;
12. SQL> alter database open;
13. SQL> alter database enable block change tracking using file '${ORACLE_BASE}/tracking/rman_ change_track.f';
14. $ rman target /
15. RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK
TO '/var/opt/oracle/flash_ recovery_area/ORCL/c_backup/% F';
16. RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
17. RMAN> CONFIGURE BACKUP OPTIMIZATION ON;
18. RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
19. RMAN> exit
I need to configure incremental backup with RMAN on a two node Solaris x86 with Oracle RAC 10g Enterprise Edition Release 10.2.0.3.0 installation.
We also use ASM to store database files, and have Oracle software installed on separate file systems (two Oracle roots for Node1 and Node2).
I have following questions:
1) where to put Flash Recovery Area (FRA)?
I saw recommendations to put FRA on the ASM, is this the best way to do it?
2) Can I put FRA on another file system (not on the ASM) which is available only from Node1? This way I can save space on the ASM.
3) Is it possible/recommended to run RMAN from Node1 only?
Below is the script used to run RMAN on the normal Oracle database (without RAC) which I need to change :
=============================================================================================
2.0 Oracle backup script: /opt/app/oracle/rman_scripts/backup.sh
Use this for daily backups, possiblly as a cron job.
Once a week run this: /opt/app/oracle/rman_scripts/backup.sh FULL
All other days of the week: /opt/app/oracle/rman_scripts/backup.sh INCREMENTAL
Note: You may have to change ORACLE_SID, ORACLE_BASE below to match your database.
=============================================================================================
#!/usr/bin/ksh
ORACLE_SID=orcl
ORACLE_BASE=/opt/app/oracle
ORACLE_HOME=${ORACLE_BASE}/product/10.2.0/db_1
PATH=${ORACLE_HOME}/bin:/usr/bin
LOGDIR=${ORACLE_BASE}/logs
LOGFILE=${LOGDIR}/rman.log
if [[ $# < 1 ]]
then
echo "usage: backup.sh FULL|INCREMENTAL"
exit;
fi
BACKUPTYPE=${1}
full='FULL'
incremental='INCREMENTAL'
if [[ $BACKUPTYPE == $full ]]
then
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup database;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;
eof
echo ''
fi
if [[ $BACKUPTYPE == $incremental ]]
then
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup database;
backup incremental level 1 database;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;
eof
echo ''
fi

Hi [email protected],
Q1) where to put Flash Recovery Area (FRA)?
A1) With RAC: on the shared storage
I saw recommendations to put FRA on the ASM, is this the best way to do it?
If you want your backups to be available for both nodes you have to use shared storage or tape using an mml library.
So if you want to use the FRA for rman backups and the database is on ASM just make ASM the standard for the FRA as well.
Q2) Can I put FRA on another file system (not on the ASM) which is available only from Node1? This way I can save space on the ASM.
A2) Than you cannot recover in case Node1 is down. Best would be to send your storage admin to a training course so he can manage the clustered raw devices needed for ASM.
Q3) Is it possible/recommended to run RMAN from Node1 only?
A3) No see A2.

Tycho

Oracle RAC 10g on VMware

I am installing Oracle RAC on 2 virtual machines using RHEL 3-U7, basically I have been able to install RAC and the software for the database. However when I run dbca to configure ASM, I get
Error When starting ASM instance on node node1
