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,
Nav

Hello,
Instead of -

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

ASM Installation on Oracle 11g Clusterware (RAC) environment

Hi All,
I am trying to setup Oracle 11g Standared Edition RAC+ASM on RedHat Linux 5.0 VM ware box. As part of this RAC setup successfully completed. For this i have used raw devices and mounted using NFS.
In many of forumns i have read that ASM installtion on a cluster envioronmnet is different than non cluster environment.
I dont know how to start ASM installtion on RAC environment. Please share any documents if you have?
Thanks,
Rakesh

will the steps need to be done on two nodes of cluster or it is sufficient on first node.
"raw device" for OCR, VOTE, SPFILE_FOR ASM and ASM DISKGROUPs
before do "raw devices" you have to fdisk(make partitions) on share storages
node1:
# fdisk /dev/sdf
# ls /dev/sdf*
node2:
# ls /dev/sdf*
don't find...,so just fdisk -> l and -> w
fdisk how? http://linux.about.com/od/commands/l/blcmdl8_fdisk.htm
Example: /etc/sysconfig/rawdevices do it every nodes
#Oracle OCR File +~280M+
/dev/raw/raw1 /dev/sdf1
#Oracle Voting File +~280M+
/dev/raw/raw2 /dev/sdf2
#Oracle ASM spfile ~50M+
/dev/raw/raw3 /dev/sdf3
#Oracle ASM DISK Group1
/dev/raw/raw4 /dev/sdg1
#Oracle ASM DISK Group2
/dev/raw/raw5 /dev/sdh1
And oracle user.. can read /dev/raw/raw* You should find on every nodes
http://oraclepitstop.wordpress.com/2008/02/15/raw-devices-on-rhel-5-or-oel-5/
ls -la /dev/raw/raw*
crw-rw---- 1 root oinstall 162, 1 Jan 13 12:53 /dev/raw/raw1
crw-rw---- 1 oracle oinstall 162, 2 Jan 13 12:53 /dev/raw/raw2
crw-rw---- 1 oracle oinstall 162, 3 Jan 13 12:53 /dev/raw/raw3
crw-rw---- 1 oracle oinstall 163, 1 Jan 13 12:53 /dev/raw/raw4
crw-rw---- 1 oracle oinstall 164, 1 Jan 13 12:53 /dev/raw/raw5
do it on node1 but you have to pass phrase on every nodes Before
http://www.puddingonline.com/~dave/publications/SSH-with-Keys-HOWTO/document/html/SSH-with-Keys-HOWTO-5.html
example:
node01:
$ ssh node01 hostname
node01
$ ssh node02 hostname
node02
- Install + Setup Clusterware:
OCR = /dev/raw/raw1
VOTE = /dev/raw/raw2
- Install Oracle Database for ASM Home
spfile for ASM = /dev/raw/raw3
- after ASM started... create disk groups from /dev/raw/raw4 and /dev/raw/raw5
- Install Oracle Database for RDBMS Home
- Create Database to use ASM diskgroups
http://www.oracle-base.com/articles/11g/OracleDB11gR1RACInstallationOnRHEL5UsingVMwareESXAndNFS.php
Did you followed the same procedure to set up Oracle 11g RAC+ASM on RHEL 5.0.I'd done(test 11gRAC) it on RHEL 4 + 11g + ASM(on raw device)
on production, I use ASMlib... + ASM + 10g

APEX Listener and RAC

Is APEX Listener RAC-capable? Neither the Installation Guide nor the APEX RAC white paper provides information. Is there some experience installing APEX Listener within a Oracle 10.2 RAC environment?
What would be the advantage / disadvantage?

Hello,
as far as I know, you can use the thin driver to connect to RAC. If I don't remember this wrong, you should be able to configure the URL like this:
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service)))What would you like to compare the RAC-Connection used by the APEX Listener with to outline advantages/disadvantages?
I think, the connection is not much different from the one you'd get when configuring a OHS that way. The EPG variant would be integrated in the RAC, but for fault tolerance you'd need some frontend server for node-failover anyway...

IS IT SUPPORTED TO CENTRALLY MOUNT THE ORACLE_HOME IN A NON-RAC ENVIRONMENT

SR 7250090.993 : (http://qmon.oraclecorp.com/qmon3/quickpicks.pl?t=t&q=7250090.993)
Technical Summary:
Customer is planing to install Oracle 10.2.0.4 and 11.1.0.x software on a Red Hat5 with NetApp storage.
Customer came across the following :
For single instance installations (as opposed to RAC installations), you must create a separate Oracle home directory for each installation. Run the software in this Oracle home directory only from the system that you used to install it. For Oracle Real Application Clusters (RAC) installations, you can use a single Oracle home directory mounted from each node in the cluster. You must mount this Oracle home directory on each node so that it has the same directory path on all nodes.
mentioned in the 10gR2 documentation link :
http://download.oracle.com/docs/cd/B19306_01/install.102/b15667/app_nas.htm#BCFIDEJA
Requirements/Expectations:
As the above statements, that customer came across is not present in 9i documentation, customer wants to understand if it is actually supported to centrally mount the 10g/11g ORACLE_HOME to many servers that are not RAC enabled.
Also, I would like to understand if the statements in documentation indicate that it is not generally recommended centrally mount the 10g/11g ORACLE_HOME or does it mean that it is not supported to centrally mount the ORACLE_HOME in a non RAC environment?
Please advice.

The binaries (executables) in an Oracle home are "linked" (link edited?) to the OS libraries on each server where the software is installed.
Unless the OS is IDENTICAL on each of the IDENTICAL(HW) servers -- that would share the Oracle home--, you could be in trouble.
The only supported configuration (I know of) where the Oracle binaries are shared between servers is 9i RAC. On 10g RAC the binaries are installed on each server.
Other wise I'd say it's NOT recommended, besides you don't save anything (execpt a cooupl of Gigs disk space).

Genclntst fail in oracle10g RAC environment

After installation of oracle 10gR2 RAC on two-node solaris10 environment ,we need to run $ORACLE_HOME/bin/genclntst to generate the Client Static Library(libclntst10.a) but it failed .We copy another successfully generated libclntst10.a file from a non-RAC oracle10g environment running on solaris10.
and it seems to work correctly. is it really OK ?,is there any difference between the libclntst10.a file in a RAC environment and in a non-RAC environment ?
thanks a lot.

Hi,
In 11g you can use the instance_id job attribute to do this.
In 10g you can do this using services.
- create a service for each instance
- create a job class pointing to each service
- grant execute on the job classes to all job owners that need to use them
- when creating a job point to the job class for the service for the instance it should run on
Oracle recommends using services instead of instances since services are more flexible and can provide high-availability and fail-over in case one instance goes down.
Hope this helps,
Ravi.

Are multiple PHYSICAL databases supported in one Oracle 10g RAC environment

Hi alls,
as of Metalink 220970.1 Oracle RAC is also supporting different databases in one cluster installation. RAC handles any resource as a service and it doesn't matter if these services belongs to only one or to different databases. You install the Oracle Clusterware only once and you create any service you want to make high available.
So is technically possible to install multiple databases on same Oracle Rac environment.
My doubts are related to SAP , does SAP certify such environments ?? we could have one SAP R/3 database and SAP BW database co-exist in a single Oracle RAC environment. or also co-exist SAP database with a non-SAP database (an already existing application) in the same Oracle Rac environment.
Any comment would be higly appreciated.
Silvio Brandani

We have ECC, BI, PI and Portal running on same Oracle RAC environment. We have one RAC for QA systems and one for PRD systems. We are not running any SAP applications along with Non-SAP applications on RAC. Keeping SAP and non-SAP apps separate would be a way to go.
Hope this helps.
Thanks,
Naveed

Create database on RAC environment - DBCA hangs on clone database creation

Hi, friends!
I have two vm´s (vmware 2) with OEL 5 installed.
I´ve installed OGI and database software sucessfully. So, my crs stack is working fine in both two nodes.
However, when i use DBCA to create a database in this RAC environment, it hangs when it gets on "clone database creation", about 52% of the progress bar.
My DBCA logs don´t point any error out. It just hangs on..
I wait about 4 hours and it doesn´t move on.
I searched and found many cases like that, including here in OTN. But it seems nobody could find a resolution to this issue.
Is there any bug about OEL 5 and database 11gR2??
More details:
I apllied the patch "p8670579_112010_LINUX" on both OGI installation (before root.sh) and databae software install (also before root.sh).
Everything worked fine.
Sorry for the grammar errors.

you can trace dbca, and you can found witch step is occurs problem.
can you paste here last 15-20 sentence of dbca trace file?

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....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.

Blank Page after fresh APEX installation

I have a running Glasfish + APEX Listener einvironment with almost 8 different DB targets --> all of them work well.
Now I tried to add another database target.
To do so I install APEX 4.2.2 in a fresh ORACLE 11.2 (there was no APEX in before) database. I do all given in the installation doc and had no error during APEX installation.
I copied an existing configuration in Listener environment and the result is, runnning the URL in Browser, a blank white PAGE with no content - no HTML content inside nor any error at client or server side.
Does anyone have a tip how to tackle this down.

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.

This would imply that setting INSTANCE_NAME in non-RAC is ignored. The usage of the word "usually" is weak.

How to create DIR/File on a raw device in RAC environment.

Hi all,
I use a shell script to create DIR and File on a raw device also it creates schema and tablespaces.
I am facing problem in creating DIR and Files on raw device.
One more thing, can multiple tablespaces be created on a raw device.
Thanks & regards,
Sanjeev

Thanks for the response. Please help me further.
About the Script - It asks for the path for creating DIR and uses shell command to create DIR. Later same path and DIR name is used to create Oracle DIR. Now in place of absolute path raw device name is passed. The same script is also used for creating tablespaces and schema.
There is second script that is .sql script that creates external table in the newly created schema. All this has been working fine on single instance Oracle server. we have tested many times but fails in RAC environment when we use raw device.
Question is - If I use filesystem will the external table's flat files and Directories be accessible to all the instances.
I have one application written in java that would be clustered and running on these oracle servers. This application would be accessing those external tables and their flat files. Will there be a problem accessing these flat files accross the instances.
Regards,
Sanjeev.
