Question for repository installation on RAC environment
Hi guys,
our RAC enviroment has two nodes: node1 and node2. The tnsnames file has 3 net servcie names. They are for node1, node2, and node(node1 and node2). Here is the example:
node1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = host1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = service_name)
(INSTANCE_NAME = node1)
node2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = host2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = service_name)
(INSTANCE_NAME = node2)
node =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = host1)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = host2)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = service_name)
When I am installing repository owner on node1, do I need to use net service name? if need, what name to use here? node1 or node?
when I register node2, I know I need to use the net servcie name, according to the installation guide. So which name do i use in this step? node1, node2 or node?
thanks in advance.
Hi,
you should use node net service name

Apex installation in RAC environment
Hi All,
I am trying for upgrading Apex in a RAC environment which is having 2 nodes "sed1p1" and "sed1p2". Is there any specific steps i need to follow.
Doi need to shutdown one node while installing Apex in other node. Any specific steps need to be followed for installation in such cases.
thanks,
NavHello,
Instead of -

Can not find solaris 64 9.0.1.5 patch for repository installation
Hi,
I found in oracle10gAS installation guide that I need to apply patch 9.0.1.5 or later in order to use an existing oracle 9 database for my repository. The problem is that I can not find oracle db 9.0.1.5 patch for solaris 64bit. The latest patch for solaris 64 is 9.0.1.4. Does anyone know if I can use the 9.0.1.4 patch or where I can find 9.0.1.5?
9.0.1.5 only exists for solaris 32 versions.
ThanksHi giorgio santandrea,
I am also facing the same error, could please tell me how you resolved that error?
Thanks & regards,

Some small questions for iMS installation
I am preparing to install iMS 5.2 with existing configuration and uer and groups iDS 5.1 on Solaris 9. Some issues confused me, please help, thanks in advance.
Q1. By the checking of iMS installation doc, Question 34 needs "Administration Server Port". Is it same as the port of my exsiting Administration server of iDS 5.1?
Q2. Now I want to set this as test env but my dc (dc=cig,dc=tcs,dc=com) is real, that means that mail server with suffix "cig.tcs.com" already has been setup and worked well, and all servers are on the same network.
I am not sure if I should change the dc to avoid any confusion after installing iMS?I've done it before which upgrade the iMS 5.1 to iMS 5.2...
steps...
uninstall the iMS 5.1...... using the uninstall....
second install the iMS 5.2
remain the iDS......
then... issue the ./imsimta dirsync -F
done.... -
Analyze job very slow in RAC environment
Hi,
I have an anlyze job which runs for 3 hrs in RAC environment (9.2.0.6).
Earlier in NON-RAC environment it used to complete in 1 hrs.
Need help in solving this issue.
Ajoy Kumar Thapahi,
This database is used for query purpose mainly.
we do huge data load during weekend into one of the table.
This table is then exchange with one of the partition of a huge partitioned table.
after that analyze job runs on this partitioned table.
The command we use for analyze is given below:
DBMS_STATS.GATHER_SCHEMA_STATS
ownname => '<owner_name>'
,estimate_percent => 05
,cascade => true
,degree => 4
,granularity=>'ALL'
I want to know, what can be the reason, this job, which runs fine in NON-RAC environment, is taking so long in RAC enviroment.
Any help is highly appreciated.

Plsql Programming Guidelines within a RAC Environment
Hi Guys,
Are there any specific guidelines you would recommend for programming within a RAC environment, in addition to the usual best practices one would adopt for writing Plsql programs? ie guidelines that would take advantage of the performance boost from the high availability feature of the RAC environment, as well as the processing power?There are realistically no guidelines that are specific to RAC (other than making sure if you're referencing V$ tables in code that you're using the GV$ version if you want data from all the nodes).
On the other hand, there are plenty of guidelines that are nice in single-node environments that potentially become necessities in a RAC environment. In particular, all the guidelines that reduce contention are useful in a single-node environment but can become critically important in a RAC environment. Anything that causes hot blocks in a single-node system can cause massive scaling problems in a RAC environment.
- If you are using permanent tables rather than global temporary tables to store temporary data, once load crosses a critical point, that can cause every session in the database to be queued up waiting for some other session to finish with the handful of blocks in this table to get sent over the interconnect from a different node in the cluster. That will bring your system to its knees.
- If you are inserting monotonically increasing keys into an index (i.e. a sequence generated primary key), you want as many of those primary key indexes to be reverse key indexes as possible (where "possible" takes into account the downside of no longer being able to do range scans on those indexes) to minimize index hot blocks and thus contention for those blocks over the interconnect.
- etc.

on RH ES3 Update 5, Oracle 10.1.0.3....
Due to some network reconf. I reinstalled CRS.
I reconfigured VIPCA and NETCA.
My current status on this rac is:
VIP is running on node: hp1
GSD is running on node: hp1
Listener is running on node: hp1
ONS daemon is running on node: hp1
Problem: When I reboot, none of these resources come up automatically. How can i configure so that it can start during reboot.
Thanks in advance,
VTThe term rolling upgrade refers to upgrading different databases or different instances of the same database in a RAC environment, one at a time, without stopping the database. Oracle supports the rolling upgrade of Oracle RAC (not OS like I wrote previously) in a cluster when both versions of the operating system are certified with the version of the Oracle Database you are running. Rolling patch upgrades are not available if the Oracle Database software is shared across the different nodes. This is the case where the Oracle home is on Cluster File System (CFS) or on shared NFS volumes. The feature is only available where each node has its own copy of the Oracle Database software.
I doubt that Redhat or Oracle Linux will support in-place upgrades from version 4 to 5. Your only option really available might be to split the RAC cluster and completely setup each node from scratch, than rebuild the cluster. There could be of few changes between EL 4 and 5 that may affect your ability to run a mixed cluster, i.e. raw device support. Sorry, I'm afraid I cannot give you any other practical advise. Perhaps you might want to check the RAC forum at RAC, ASM & Clusterware Installation
To answer you question about the difference with Oracle Linux. The same versions of Oracle Linux and Red Hat Enterprise are binary compatible. For Oracle Linux 5.5, x86_64, you have an option to install the Unbreakable Enterprise Kernel (UEK), which contains a newer and Oracle optimized version of the kernel, currently 2.6.32. Oracle Linux provides a free public yum repository for software management and other Oracle specific packages. For access to patches you need a subscription to the Unbreakable Linux Network (ULN).

Is a gateway mandatory for RAC environment?
Question:
Is a gateway mandatory for RAC installation, general on RAC environment?
*..when yes, why?*
Many thanks
I make this test with my only one RAC node
1. Run with gateway:
[oracle@linux1 ~]$ crs_stat -t
Name Type Target State Host
ora....SM1.asm application ONLINE ONLINE linux1
ora....X1.lsnr application ONLINE ONLINE linux1
ora.linux1.gsd application ONLINE ONLINE linux1
ora.linux1.ons application ONLINE ONLINE linux1
ora.linux1.vip application ONLINE ONLINE linux1
ora.orcl.db application ONLINE ONLINE linux1
ora....l1.inst application ONLINE ONLINE linux1
ora....test.cs application ONLINE ONLINE linux1
ora....cl1.srv application ONLINE ONLINE linux1
[oracle@linux1 ~]$ srvctl status database -d orcl
Instance orcl1 is running on node linux1All thing seem correct!
2. run without gateway (blank setting):
[oracle@linux1 ~]$ crs_stat -t
Name Type Target State Host
ora....SM1.asm application ONLINE OFFLINE
ora....X1.lsnr application ONLINE OFFLINE
ora.linux1.gsd application ONLINE ONLINE linux1
ora.linux1.ons application ONLINE ONLINE linux1
ora.linux1.vip application ONLINE OFFLINE
ora.orcl.db application ONLINE OFFLINE
ora....l1.inst application ONLINE OFFLINE
ora....test.cs application ONLINE OFFLINE
ora....cl1.srv application ONLINE OFFLINE
[oracle@linux1 ~]$ srvctl status database -d orcl
Instance orcl1 is not running on node linux1Something is false!By default, the server's default gateway is used as a ping target during the Oracle RAC 10g VIP status check action.
Upon a ping failure, Oracle will decide that the current interface where the VIP is running has failed, and will initiate
an interface / internode VIP failover.
In above case, we used just one node for CRS installation, so the VIP coudn't failover to other nodes and thus reported additional error like :
CRS-1006: No more members to consider
CRS-0215: Could not start resource 'ora.dbtest2.vip'.
Try ->
A parameter FAIL_WHEN_DEFAULTGW_NOT_FOUND in the file
$ORA_CRS_HOME/bin/racvip to address this problem.
The following steps will fix the VIP starting problem for above mentioned scenario.
1- stop nodeapps
2- As root,
vi the script $ORA_CRS_HOME/bin/racgvip and change the value of
variable FAIL_WHEN_DEFAULTGW_NOT_FOUND=0 .
3- start nodeapps and you should see the resources ONLINE
You may proceed with netca and dbca to create a RAC database after this. -
Questions on sqlnet.ora, listener.ora files in RAC environment.
Experts,
I've some confusion with below files in RAC environment.
sqlnet.ora
listener.ora
These files are available in two locations: <GRID_HOME> & <DB_HOME>.
My questions:
1. Why do we have two versions of files ?
2. When I query lsnrctl status from BOTH the homes, it says it is using listener.ora from <GRID_HOME> as shown below.
Listener Parameter File D:\app\11.2.0\grid\network\admin\listener.ora
3. What is the use of files which are in <DB_Home>
4. If you make some changes to listener using "Netmgr" tool, we expect it will update listener.ora in <GRID_HOME>. Interestingly, it is changing the contents of listener.ora in <DB_HOME> .
Can anyone please clarify it ?
Thanks in advance.859875 wrote:
1. Why do we have two versions of files ? In the past, the CRS s/w did not include ASM (ASM did not provide support for cluster voting and registration disks). Thus the networking components such as SQL*Net and the Listener were not part of the CRS installation.
With Grid Infrastructure, ASM supports cluster voting and registration disks and is recommended to be used for that (as oppose to the old style of raw disks or using an external cluster-based cooked file system like <i>ocfs</i>). And with ASM comes the SQL*Net networking layer and s/w (such as the Listener). As ASM ships with Grid Infrastructure, it now also includes the same networking layer as what the RDBMS installation will. Thus both <GRID_HOME> and <DB_HOME> will contain the same networking components.
However, only a single Listener is for example needed. And that can only run from a single base location. So for operational use, only one version will be actively in use. -
During the installation of grid infra(cluster) for Oracle 11.2 RAC one.
Good Day All, and thanks in advance…
During the installation of grid infrastructure(cluster) for Oracle 11.2 RAC One Node on AIX6.1 ( PROD) , ASM used. I am getting below errors when executing ./root.sh
Upon investigation ,I managed to get note: 1068212.1 from the support oracle site ( see below for details) . I might be hitting Unpublished bug 8670579. I also logged Severity 2 SR with Oracle support to get the bug/patch fix and no one has attended the call.
This might be configuration issue or otherwise , if you have experienced the same issue please assist ? ( if you need more logfiles please feel free to request)….
I ran the Cluster Verify Check – all passed.
Many Thanks

We are also trying to install 11.2.0.2 Grid infrastructure for Oracle RAC One Node on AIX 6.1. We did a POC in our lab environment and after much struggle got that working. Now we are building 4 clusters in the production environment and the first cluster installation failed while running root.sh on node2. We already have a Sev1 ticket open with Oracle Support but have not heard anything.
Here is root.sh output from node2. The two node names are p01dou416 and p01dou417.
CRS-4402: The CSS daemon was started in exclusive mode but found an active CSS daemon on node p01dou416, number 1, and is terminating
An active cluster was found during exclusive startup, restarting to join the cluster

Manually Setting up a Standby Database for RAC Environment
Hi,
I am a Junior DBA so apologies if this sounds like a silly question.
We have production 11g Extended RAC environment setup. Management have asked for a separate single instance database be setup as a standby DB on a separate 'cold' server in case we lose complete connection to both sides of the RAC. I read up on Oracle Data Guard and presented this as a solution, but they seem adamant about manually going in and copying out the latest backup and archive logs over to the standby database.
Can this be done? I mean, can ASM managed backup files and archive logs from one database be simply copied out of the backup directory and imported into a completely separate database as easy as that?
We are using ASM to manage to data files on the RAC. My understanding is that we cant manually access the files on an OS level when using ASM, but maybe I am wrong. Any help or opinions on this would be greatly appreciated.
Rgs,
RobHi,
Can this be done? I mean, can ASM managed backup files and archive logs from one database be simply copied out of the backup directory and imported into a completely separate >database as easy as that?Yes, but depends on DB version.
what is the DB version.
from 11g you have cp command so there is a possibility to copy generated archive logs to standby location, so that you can apply..
In 10g there is no such option. you need to create a standby database. with automatic shipping

A sample server specification for Oracle RAC environment
Hi,
Our project has decided to change the single instance database to a RAC environment. Can any one provide a sample server specification to be analysed based on our project.
For example minimum processor/RAM....
ThanksThis is the simplest installation you can get, but if you want to do a fast response file based installation, there it is.

Configuring our RAC environment Questions
The environment consists of Sun Solaris 10, Veritas, and 10g RAC:
Questions:
I need to know the settings and configuration of the entire software stack that will be the foundation of the oracle RAC environment....Network configurations, settings and requirements for any networks including the rac network between servers
How to set up the solaris 10k structures: what goes into the global zones, the containers, the resource groups, RBAC roles, SMF configuration, schedulers?
Can we use zfs, and if so, what configuration, and what settings?
In addition, these questions I need answers to:
What I am looking for is:
-- special hardware configuration issues, in particular the server rac interconnect. Do we need a hub, switch or crossover cables configured how.
-- Operating System versions and configuration. If it is Solaris 10, then there are more specific requirements: how to handle smf, containers, kernel settings, IPMP, NTP, RBAC, SSH, etc.
-- Disk layout on SAN, including a design for growth several years out: what are the file systems with the most contention, most use, command tag depth issues etc. (can send my questionnaire)
-- Configuration settings\ best practices for Foundation suite for RAC and Volume manager
-- How to test and Tune the Foundation suite settings for thru-put optimization. I can provide stats from the server and the san, but how do we coordinate that with the database.
-- How to test RAC failover -- what items will be monitored for failover that need to be considered from the server perspective.
-- How to test data guard failures and failover -- does system administration have to be prepared to help out at all?
-- How to configure Netbackup --- backupsAnswering all these questions accurately and correctly for you implementation might be a bit much for a forum posting.
First I'd recommend accessing the Oracle documentation on otn.oracle.com. This should get you the basics about what is supported for the environment your looking to set up, and go a long way to answering your detailed questions.
Then I'd break this down into smaller sets of specific questions and try and get the RAC axters on the RAC forum to help out.
See: Community Discussion Forums » Grid Computing » Real Application Clusters
Finally Oracle Support via Metalink should be able to fill in any gaps int he documentation.
Good luck on your project,

RAC environment setup for OEM Grid Control
Hi All,
One of my customer is setting up RAC environment for OEM Grid Control, he has following questions.
1) Can I use the DirectNFS client on each RAC node to mount SAN storage created with an OCFS2 filesystem?
2) Can I use the DirectNSF client to mount the shared filesystem loader directory?
3) Should I be using DirectNFS for the shared filesystem loader at all? Or should I just use a normal Linux NFS mount?
4) Is OCFS2 preferred over NFS for the shared filesystem loader?
Any information is highly appriciated.
Thank you,
BhavinPlease check the below doc

Question on pfile in RAC environment
DB version:10GR2,11GR2
OS Version: Solaris, AIX, Linux
Lets say i have a 2 node RAC environment.
DB name is : jerry
I have a datagroup called DATA7
Node1's pfile would only contain a single like as shown below
$ cat initjerry1.ora
SPFILE='+DATA7/jerry/spfilejerry.ora'Likewise, for Node2
$ cat initjerry2.ora
SPFILE='+DATA7/jerry/spfilejerry.ora'Am i right?yes, this works. But I don't think this pfile is even needed because afair srvctl will know to use the spfile on ASM. I remember that I had some trouble with one install a while ago because there was also an spfile on each server. This would not get touched by automatic startup and shutdown but when I started the instance manually with sqlplus (and without arguments) this spfile would be used and it caused a lot of confusion for me.
