Veritas with Oracle RAC

Some days long ago one of my senior DBA invoked some GUI tool which was like web page for monitoring resources of Veritas SFRAC.
I would like to know how to find URL for this??

You and your management do realise that Windows does not feature in the Top 500 clusters in the world (2013/11 stats)? That Linux is the preferred operating system amongst the biggest and fastest clusters in the world?

Now why would you want to use Windows for an Oracle cluster, when the top clusters in the world clearly show that such a choice is not ideal ito TCO, performance, scalability, flexibility and so on?
It is not that Windows is a bad o/s. It is simply that when it comes to computer clusters, Linux is significantly better. As operating system family stats of the top 500 clusters on this planet, shows.

CRS10g patchset을 적용한 이후 Veritas SF Oracle RAC 관련 MODULE

Problem Description
다음은 SF(Storage Foundation) Oracle RAC를 구성하기 위하여 Oracle CRS
PATCHSET 등을 적용하기 전에 SF Oracle RAC Veritas libraries 를 ORACLE_HOME에 설치해야 한다는 내용입니다.
또한, ORACLE CRS 패치 Version 을 올리면서 Veritas 쪽 관련하여 필요한
Veritas skgxp module 등이 설치 과정에 빠져 있거나 Veritas library file들이 overwrite되어 에러를 만나는 경우를 볼 수 있습니다.
이런 관점에서 Veritas storage foundation 을 설치하고 oracle CRS stack을
설치 또는 갱신하는 과정에서 만날 수 있는 에러에 대해 원인 및 해결방안을 알아봅니다.
에러 증상
다음은 CRS 10.2.0.3.0 Patchset이 설치되면서 Veritas library가 overwrite 되면서 발생하는 에러임.
Veritas clusterware 5.0 not recognized by Oracle due to the fact that Veritas libraries over written with crs 10.2.0.3.0 patchset installation.

Installing and Configuring SF Oracle RAC Software
Veritas 에서 제공하는 Storage/Clusterware 관련한 절차는 이 문서에서 생략합니다.
Install CD 안의 installsfrac 스크립트 수행 session 에서 RAC software installation을 하는 과정이 들어갑니다.
Veritas가 제공하는 SF Oracle RAC 5.0 installation 문서를 보면 다음과 같은 내용이 포함되어 있습니다.
아래 내용에는 SF Oracle RAC component 들을 설치하는 과정만 기술합니다.
# cd /cdrom/storage_foundation_for_oracle_rac
# .installsfrac -configure
Note: Do not run root.sh yet, but return to the installsfrac session from step 15.
19 In the installsfrac session, press Return. The installsfrac utility now verifies
the database software installation, copies the SF Oracle RAC libraries to $ORACLE_HOME, and relinks Oracle on each node in the cluster.

Before you run the root.sh script, you need to add the init.cssd.patch.
a. Open another window on the system where you are running the installer
b. Log in as superuser
c. Change to the directory where the patch is to be copied:
For Oracle 10gR1:
# cd $CRS_HOME/css/admin
# cp /opt/VRTSvcs/rac/patch /init.cssd-10gR1.patch .
For Oracle 10gR2:
# cd $CRS_HOME/css/admin
# cp /opt/VRTSvcs/rac/patch /init.cssd-10gR2.patch .
d. Run the following command to install the patch:
For Oracle 10gR1:
# patch < init.cssd-10gR1.patch init.cssd
For Oracle 10gR2:
# patch < init.cssd-10gR2.patch init.cssd
e. Run the root.sh script. For example:
# cd $CRS_HOME
# ./root.sh
This starts the CRS daemons on the node where you enter the command.

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

Sun Fire V490 x 2 servers with Oracle RAC facing Split brain problem

Hi all,
I have Sun Fire V490 x 2 servers with Oracle RAC and they faced a Split brain problem. One of the node's database instance has gone down, The DBA claims it is due to network problem, but as such the networks are OK. We use the on board CE1 interface for Cluster interconnect and CE0 as the public interface.
Did anybody face this kind of a problem? Could this be a hardware/OS patch problem?
I had kept a continuous ping for 24 hours after this happened last time and the output shows no packet loss
Many thanks in advance.
Ushas Symon

In order to diagnose this properly, you'll need to provide too much detail and far too many log files for a generic discussion forum to handle.
Use your service contract and open a support case.
Because a cluster environment is involved you'll likely end up talking to the cluster support staff.
They can analyze hardware and software errors as well as review whether you configured the systems in a supportable fashion.
Be prepared to make a direct connection to each system and gather data using such as by using the Explorer tool. The technical support staff will tell you what they will actually need.

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.

Tuxedo with Oracle-RAC

Tuxedo -Oracle RAC ,
We are planning to upgrade the Tuxedo Environmet to o Support Oracle-RAC , with Single Database server with Two Instances .
***At the moment we have ceratin Tuxedo Services ( part of a transaction ) to connect Database , which is used by more than One Application ie The connection Services to the Databse is COMMON.***
Eg: we have service named DBSERVICE1 , which is connecting to a datbases , which also part of a Transaction , This DBSERVICE1 is used by more than one channels ( ATM/internet banking , phone banking etc )
we have more than one service like DBSERVICE1
With this architecture how we can effectively achieve Tuxedo -Oracle RAC High Availability.
Is is possible to specify in the Tuxedo Configuration like this " if the instance1 is down , use the Instance2"?+
Thanks in Advance.
Nadeer.

Hi Nadeer,
In Oracle RAC 10g a single global transaction that spans more than one RAC instance, yet connected to a single database will not work, i.e., you may not get transactional integrity. To solve this problem, Tuxedo introduced RAC support by way of the TUXRACGROUPS environment variable. This environment variable tells Tuxedo about the RAC configuration, i.e., which RAC instances are connected to which RAC databases. Actually it tells Tuxedo which groups of Tuxedo servers can safely participate together in a single global transaction. Using that environment variable, Tuxedo will alter its request routing algorithm so that once a transaction is started, all subsequent service requests that are part of that transaction will only be routed to servers in Tuxedo groups that can safely participate in the transaction. So if we use a simple example where there are two RAC instances R1 and R2 connected to a single database D1 and we have Tuxedo groups G1, G2, G3, and G4, where the openinfo string for G1 and G3 connect to R1 and G2 and G4 connect to R2. If a server in G1 starts a transaction, or is called by a client that has started a transaction (assuming TUXRACGROUPS has been defined properly), Tuxedo will only route all subsequent requests that are part of that transaction to servers in G1 or G3. Thus Tuxedo will prevent a transaction from ever spanning 2 or more RAC instances connected to the same database.
Again, I encourage you to read the documentation for RAC support in Tuxedo as it gives several examples and describes in detail how to define TUXRACGROUPS.
Also note that this entire problem essentially goes away in Oracle RAC 11g.
Regards,
Todd Little
Oracle Tuxedo Chief Architect

SAP ECC6.0 installation with Oracle RAC

Hi Expert,
Current we working on SAP ECC6.0 installation with Oracle 10G RAC on AIX 5.3. The RAC are running on two nodes (servers). And we are using GPFS filesystem (not running on HACMP).
Overall we had completed the Oracle RAC installation (CRS+RDBMS) and tested the oracle failover and it work find. Now we want to start with the SAP installation (with HA). In the SAP installation documentation, it did request to create a virtual hostname on the node and execute the sapinst scripts with below command line.
#./sapinst SAPINST_USE_HOSTNAME=ascs00
But if we are running on Oracle RAC + GPFS do we need to specify the virtual hostname? If not, which hostname i should use to install the HA for SAP? Please advice.
Regards.

And then I'd continue with the documentation at:
SAP on Oracle => SAP on Oracle Real Application Clusters (RAC)
There you can find several installation guides for windows/UNIX/Linux

Compatibility with Oracle RAC 10g and E-business 11i ?

Hi netpros,
I am currently helping the sales guys with a tender. The customer requires the solution to be compatible for delivering Oracle RAC 10g and e-business 11i. we are proposing a combination of Cat6509E for the core with Infiniband server switches. Are these devices OK for use with Oracle. I have not much experience with Data centers and so any help is much appreciated.

Hi,
It just so happens Cisco have a paper on exactly this subject (Oracle and e-business 11i) here:
http://www.cisco.com/application/pdf/en/us/guest/netsol/ns50/c649/ccmigration_09186a00807688ce.pdf
The design is somewhat OTT as it includes everything which Cisco thinks may be even vaguely useful, including ACE and FWSM modules. However, it's very useful as a comparison document and does include some good design tips, and the references at the end are also worth following up.
I wouldn't want to get into the whole Infiniband vs Fiber Channel argument (the doc uses MDS switches) but both work just fine in the DC environment.
HTH

IBM VIOS with Oracle RAC

Hi everybody,
I have a case of RAC implementation but they are planning to use VIOS (IBM Virtual I/O Server) for OCR, Voting and ASM.
Questions:
1) Metalink says VIOS is supported for RAC:
http://www.oracle.com/technology/products/database/clustering/certify/tech_generic_unix_new.html
"VIOS Virtual SCSI for ASM data storage and associated raw hdisk based Voting and OCR "
2) Any implementation experience with 10g R2 (10.2.0.3+) and IBM VIOS
3) What need to know the Storage or System Administrator to setup storage for RAC using VIOS (for OCR, Voting, ASM)
Regards,
Miguel.

Thanks for your update. Could you describe how do you setup your current VIO server implementation to support Oracle RAC?
In our case:
1) Physical storage is provided by EMC
2) We have two VIO Server to provide storage and network to each LPAR.
3) One VIO server works with one LPAR, so we have one VIO server behind each LPAR.
As you know, we normally setup shared raw devices for OCR, Voting Disks and ASM. The storage administrator does not know how to setup the "virtual" shared storage (provided by VIOS) between each LPAR.
Please, any advice if you know that.

Enterprise User Security (EUS) with Oracle RAC database

Hi all,
i'm experiencing a problem configuring centralized AAA on Oracle OID for Oracle RAC Database.
My environment is:
1) Oracle OID 10g (192.168.15.245 - rh4oidserver.klab.it)
2) Oracle RAC database 11g
I successfull configured a standalone Oracle Database to authenticate user in OID centralized repository, but i'm experiencing different problem to do, with RAC, same things.
In dept:
1) Oracle RAC works correctly and internal user (SYS,Oracle, ecc.) are correctly authenticated and authorizated against database
2) Oracle RAC register himself in OID (see attached snapshoot)
3) I run sqlplus to connect on Oracle RAC using OID users and i get following error: ORA-28030 Server encountered problems accessing LDAP directory service
Using a sniffer, i can see a reset message after SSL handshake (SSL v3 encrypted alert), but i don't undenstand root cause....
Host file on RAC server is:

# that require network functionality will fail.

Hello bipkary,
what version are you using?

Problem with Oracle RAC with DRCP and persistent connections

Hello,
I am having a problem that has me stumped. I cannot get SCAN, and DRCP to work together nicely.
Right now, I can connect through my scan hostname fine without connection pooling, once I enable it I start having connection time outs. I found if I specified outbound_connection_timeout in sqlnet.ora that it times the connection out to the time I set in there. If I don't set this option I get a "ORA-12170: TNS:Connect timeout occurred".
The odd thing is I can leave connection pooling on and connect to one of my rac instances individually and it doesn't experience this problem. The only time it pops up is if I combine multiple rac instances (Through the use of SCAN or tnsnames.ora) and I enable connection pooling.
I don't know which direction to go to even diagnose this, so any and all help is appreciated.
Thank you.

Hi,
You need to detail the problem. Enable TRACE SQL*NET on the server and client using note below.
How to Enable Oracle SQLNet Client , Server , Listener , Kerberos and External procedure Tracing from Net Manager [ID 395525.1]
Also you can try check this note:
11g: ORA-12170 With Combination RAC, DRCP and a Firewall [ID 953277.1]
Hope this helps,
