Ancient RHEL3 Running Oracle Rac 10G - memory utilization question

As all good things must happen the crappy old systems that never get upgraded come back to bite you.
I have a 4 node RAC cluster running Linux RHEL3. I know .. would love to upgrade it .. but that will take time. Looking for at survival at this point. The system is experiencing High I/O wait. Now, my background is mainly Solaris/AIX and not Linux. So as I work through this problem I am unsure of what I am seeing, since Linux maybe handling memory differently on this OS.
This is what I am seeing:
High I/O wait as shown by TOP
Disk Access Time and Utilization : pretty good .. no device utilized over 30% and <20 millisecond response times from the drives
The real Question is in memory usage:
Host: 32GB
OS: Red Hat Enterprise Linux AS release 3 (Taroon Update 9)
model name : AMD Opteron (tm) Processor 880
Please .. I know its old but try and not laugh.......
The box has 32GB of Memory and I am told by the DBAs that OEM is reporting that SGA is sized correctly and memory ISN"T the problem. But disk access time/utilization isn't really pointing to a particular problem with the OS. The disks are all provided by a SAN.
However, when I look at TOP .. I see that the largest oracle process in RSS size is 8G .. now on all other platforms .. AIX/Solaris when using TOP .. all oracle processes that connect to the SGA will show the full size of SGA. So this is my question. Does Linux do this differently... for the DBAs to tell me SGA is set to 20GB and to only see top showing process with 8GB .. this has me confused. Is the SGA really being set to 20GB????
I can see in a pmap <oracle process> that it appears to be attached but just wanting to rule out a simple Oracle / Linux configuration problem first.
I've included a pmap of both a current Linux process on the troubled system and a pmap of a current oracle solaris host.

It could be that you have a dual fibre via HBA to the SAN and that one port is faulty (e.g. bad cable), thus reducing your I/O to the SAN to a single I/O path.
It could be caused by hotspots on a LUN - and likely because ASM is not being used, this hotspot cannot be automatically load balanced.
Or it could be a number of other factors, such as poorly designed and written app code that performs multiple passes through the same data sets, abuse of PQ slaves, etc.
How does your storage layer look? What do you use for SAN connectivity? What diver s/w is used? How are the LUNs used (cooked/raw)? Is ASM used? What does Oracle session and instance reports ito I/O wait times? Which datafiles are being hit the hardest? Is acrhive logging used and what is the frequency of log switches? Etc. etc.
Memory utilisation does not impact I/O, unless it is swap I/O. And these symptoms are easily seen and easily diagnosed. So I would expect that high memory utilisation may be a symptom, as is I/O wait times, of a potential underlying problem. But it would be premature to blame one (e.g. I/O wait times) on the other (e.g. memory utilisation).

Oracle RAC 10g on Solaris 10 in a non-global zone

I need to run Oracle RAC 10g on Solaris 10 in a non-global zone as I must cap the CPUs used for Oracle licensing limitations. My question is a simple one, but one for which I'm getting conflicting information depending upon whom I ask.
If I want to run RAC in a non-global zone on two nodes, does this require the use of Solaris Cluster?
I know there are good reasons to use Solaris Cluster, but the company for which I work cannot afford the additional expense of Solaris Cluster at this time. Is it possible to run Oracle RAC 10g in a capped container without Solaris Cluster or is Solaris Cluster absolutely required?
Thanks in advance for any insight you can provide.

AFAIK, Oracle 10g RAC is not supported in solaris containers.
It is however supported in Solaris zone clusters...in order to use it, you would have to use Sun Cluster 3.2 (iinm).

Running Oracle database 10g and 11g on same 5 RAC nodes

Hello Gurus,
Could any body throw light if I can install and sucessfully run Oracle database 10g and 11g on the same Oracle RAC installation setup.My setup is below
Number of nodes-5
OS- windows 2003 or RHEL5
storage- DELL EMC SAN
Clusterware- oracle version11g
File system-Automatic storage management(ASM)
After I successfully setup clusterware,ASM on the nodes,I would want to install 11g database on all 5 nodes .
Then Install 10g database on only 3 of the nodes using the same clusterware.
What are your views on the same.
Also FYI... as per metalink node 220970.1(RAC: Frequently Asked Questions) one can do such a setup.
what iam looking for is practical experience if anyone has implemented this in production system,if yes any issues faced and how tough it is to support.
Thanks,
Imtiyaz

You could run an 11g database and 10g database on the same cluster as long as you use Clusterware 11g.
The administration aspect will drastically change according to the platform you run on. As of now, it appears you don't know whether it will be Linux or Windows.
It would be practical to support the same database release.

I had this problem and resolved it by transporting the file to the installation server with the correct ftp datatype (binary).
On page 54 of the install guide (..Server\Oracle_Business_Intelligence\doc\doc\bi.1013\b31765.pdf) that comes with the installation files, there is an instruction to make sure that any ftp activity is done in binary.
This may not have occured with the license.xml file if you use a tool which offers the "feature" of automatic datatype recognition.
Hope this helps.

Since you didn't say "thank you", I assumed my time was of no value to you.
However, I shall try again.
There is no relationship between instance failure and VIP failover. How can there be? What if you are running ten instances on each node, and one fails? Would you want the VIP to relocate? And I've already told you how to test it: kill the node. Just reboot it.

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

Loading http://abc:8889/forms/java/printtext.jar from JAR cache
This tells me you are using a 3rd party or locally developed Java Bean to perform some type of print function. Is this correct?
java.lang.ClassNotFoundException: java.io.IOException: open HTTP connection failed.Does your printtext.jar Java Bean need to open an HTTP connection in order to print?
Have you been able to print in the past using this Java Bean? Where did you get the Java Bean?
RegisterWebUtil - Loading WebUtil Version 10.1.2.0Your form appears to be using WebUtil. Has it been successfully configured?
Honestly, you need to list the following minimum information when you post a question; it gives us all or most of the information we need to help you and it eliminates the need for us to ask for this information. Please always include:
* Forms Version (eg; 10.1.2.0.0 not 10g)
* Java Version
* Client OS version
* What you were doing when the error occured.

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
Andrew.

Regarding Hangcheck timer configuration in Oracle RAC 10g r2 installation

Hi,
Is it necessary to configure hangcheck timer in Oracle RAC 10g R2 installation .
Can somebody guide when we should install the hangcheck timer in Linux oracle 10g R2.
Best Regards
Gupteswar Prasad Mishra
Edited by: Gupteswar on Jan 25, 2010 8:42 PM

yes, its recommended to configure hangcheck timer in RAC configuration
Configure the Hangcheck Timer
The hang-check timer is loaded into the Linux kernel and checks if the system hangs. It will set a timer and check the timer after a certain amount of time. There is a configurable threshold to hang-check that, if exceeded will reboot the machine. Although the hangcheck-timer module is not required for Oracle Clusterware (Cluster Manager) operation, it is highly recommended by Oracle.
cat /etc/rc.local
modprobe hangcheck-timer hangcheck_tick=1 hangcheck_margin=10 hangcheck_reboot=1
