Configure SSH Manually for RAC 4 node Cluster

Configure SSH Manually for RAC 4 node Cluster

Before 11gR2, Grid Infrastructure Installation requires SSH to be configured. But from 11gR2 onwards, using Oracle Universal Installer the ssh setup can be done by using the  'SSH Connectivity' button.

And also to run cluvfy, SSH configuration is needed. Below are the steps for manual SSH configuration.

**************************************** Step By Step Procedure ******************************************************

#########################################
# 1) Create Necessary Folders & Permissions
#########################################

Login to ORACLE user HOME and create a directory called .ssh and permissions should be given like below.

$ cd $HOME

$ mkdir .ssh

$ chmod 700 .ssh

cd /u01/home/oracle/.ssh

=====================================================================================================================
Do Step 1 in all the 4 nodes.
=====================================================================================================================

#########################################
# 2) Create Keygen
#########################################

On Node 1 ( hostU13 )
---------------------------

no_sid @ hostu13:/u01/home/oracle/.ssh
> ls -ltr
total 4
-rw-r--r-- 1 oracle oinstall 407 Dec 18 05:40 known_hosts

/usr/bin/ssh-keygen -t rsa

no_sid @ hostu13:/u01/home/oracle/.ssh
> /usr/bin/ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/u01/home/oracle/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /u01/home/oracle/.ssh/id_rsa.
Your public key has been saved in /u01/home/oracle/.ssh/id_rsa.pub.
The key fingerprint is:
af:75:72:de:a8:1c:1e:0a:11:64:9e:5b:cd:0e:30:b2 oracle@hostu13

Note :
---------

Accept the default location for the key file, Enter and confirm a passphrase. (you can also press enter twice)

no_sid @ hostu13:/u01/home/oracle/.ssh
> ls
id_rsa  id_rsa.pub  known_hosts

no_sid @ hostu13:/u01/home/oracle/.ssh
> ls -altr
total 20
-rw-r--r-- 1 oracle oinstall  407 Dec 18 05:40 known_hosts
drwxr-xr-x 4 oracle dba      4096 Dec 18 21:58 ..
-rw-r--r-- 1 oracle oinstall  400 Dec 18 22:02 id_rsa.pub
-rw------- 1 oracle oinstall 1675 Dec 18 22:02 id_rsa
drwx------ 2 oracle oinstall 4096 Dec 18 22:02 .
no_sid @ hostu13:/u01/home/oracle/.ssh

=====================================================================================================================
Now we have got 2 files generated "id_rsa.pub" & "id_rsa"
Do Step 2 in all the 4 nodes.
=====================================================================================================================

#########################################
# 3) Create Authorization Keys
#########################################

Now we will create an authorization key file from "id_rsa.pub" file in all the nodes.

cat id_rsa.pub >> authorized_keys.$HOSTNAME

no_sid @ hostu13:/u01/home/oracle/.ssh
> cat id_rsa.pub >> authorized_keys.$HOSTNAME
no_sid @ hostu13:/u01/home/oracle/.ssh
> ls -ltr
total 16
-rw-r--r-- 1 oracle oinstall  408 Dec 18 06:32 known_hosts
-rw-r--r-- 1 oracle oinstall  400 Dec 18 23:10 id_rsa.pub
-rw------- 1 oracle oinstall 1675 Dec 18 23:10 id_rsa
-rw-r--r-- 1 oracle oinstall  400 Dec 19 07:44 authorized_keys.hostu13
no_sid @ hostu13:/u01/home/oracle/.ssh

Copy All the authorized_keys.$HOSTNAME from all the 4 nodes to Node 1, Once copied it will be like below,

no_sid @ hostu13:/u01/home/oracle/.ssh
> ls -ltr
total 28
-rw-r--r-- 1 oracle oinstall  400 Dec 18 22:02 id_rsa.pub
-rw------- 1 oracle oinstall 1675 Dec 18 22:02 id_rsa
-rw-r--r-- 1 oracle oinstall 1631 Dec 19 07:49 known_hosts
-rwxrwxrwx 1 oracle oinstall  400 Dec 18 22:06 authorized_keys.hostu13
-rw-r--r-- 1 oracle oinstall  400 Dec 19 07:48 authorized_keys.hostu14
-rw-r--r-- 1 oracle oinstall  400 Dec 19 07:49 authorized_keys.hostu15
-rw-r--r-- 1 oracle oinstall  400 Dec 19 07:49 authorized_keys.hostu16
no_sid @ hostu13:/u01/home/oracle/.ssh
>

Now Create  a file called "authorized_keys" which will hold all the 4 nodes key files.

cat *.host* >> authorized_keys

no_sid @ hostu13:/u01/home/oracle/.ssh
> cat *.host* >> authorized_keys
no_sid @ hostu13:/u01/home/oracle/.ssh
> ls -ltr
total 32
-rw-r--r-- 1 oracle oinstall  400 Dec 18 22:02 id_rsa.pub
-rw------- 1 oracle oinstall 1675 Dec 18 22:02 id_rsa
-rw-r--r-- 1 oracle oinstall 1631 Dec 19 07:49 known_hosts
-rwxrwxrwx 1 oracle oinstall  400 Dec 18 22:06 authorized_keys.hostu13
-rw-r--r-- 1 oracle oinstall  400 Dec 19 07:48 authorized_keys.hostu14
-rw-r--r-- 1 oracle oinstall  400 Dec 19 07:49 authorized_keys.hostu15
-rw-r--r-- 1 oracle oinstall  400 Dec 19 07:49 authorized_keys.hostu16
-rw-r--r-- 1 oracle oinstall 1600 Dec 19 07:51 authorized_keys
no_sid @ hostu13:/u01/home/oracle/.ssh

Now FTP the authorized_keys file to all the nodes to /u01/home/oracle/.ssh location

=====================================================================================================================

#########################################
# 4) Test SSH
#########################################

Now run the below commands, from all the nodes. Initially it may prompt like below, Give "YES". "known_hosts" file will be added with the RSA key values.

Below commands should return date.

ssh hostu13 date
ssh hostu14 date
ssh hostu15 date
ssh hostu16 date

no_sid @ hostu13:/u01/home/oracle/.ssh
> ssh hostu13 date
The authenticity of host 'hostu13 (192.168.29.205)' can't be established.

# 1) Check the Snapshot Controlfile
#########################################

RMAN> show snapshot controlfile name;

RMAN configuration parameters for database with db_unique_name oralin01P_STL are:

=====================================================================================================================

#########################################
# 2) Reason for Failure
#########################################

Error is occuring when autobackup of controlfile is being done. Whenever oracle tries to update the recovery catalog, it checks with recovery catalog to find how much updated recovery catalog is.

So when trying to backup the controlfile, RMAN tries to write the information to snapshot controlfile. If a snapshot controlfile is not available then RMAN creates a new file.

In our Case, both updating the existing file and new file creation failed with the below error.

                                               Y    oralin01P_STL/
ASMCMD [+oralin01P_RECO] >

No file Exists

##########################
## Solution
##########################

configure snapshot controlfile name to '+oralin01P_RECO/snapcf_oralin01p.f';

RMAN> configure snapshot controlfile name to '+oralin01P_RECO/snapcf_oralin01p.f';

old RMAN configuration parameters:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2/db_4/dbs/snapcf_oralin01p_2.f';
new RMAN configuration parameters:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+oralin01P_RECO/snapcf_oralin01p.f';
new RMAN configuration parameters are successfully stored
starting full resync of recovery catalog
full resync complete

=====================================================================================================================
New file named snapcf_oralin01p.f is created.
=====================================================================================================================

ASMCMD [+oralin01P_RECO] > ls -lt
Type         Redund  Striped  Time             Sys  Name
                                               Y    oralin01P_STL/

Different Methods to find or Check whether the installed Oracle Client Software is 32 bit or 64 bit in Windows Environments

Some times we may need to check whether the oracle client software which is installed in Windows Environments is 32 bit or 64 bit, and this sometimes comes mostly because of the application team who bugs us and say that we need 64 bit client sofware or 32 bit.

Eventhough they have same version of client software, still they will say i want it. This is app team's default behaviour. ( Just Joking ).

If you wanna check in Unix / Linux Environments, please use below link.

http://stepintooracledba.blogspot.com/2013/08/different-methods-to-find-or-check.html

Below are the two methods which i use mostly to find out the bit size.

**************************************************************** Methods ******************************************************************************

#########################################
# 1) Using Task Manager
#########################################

In Command Prompt, Change directory (cd) to Oracle Client Home bin directory ( $ORACLE_HOME/bin ) and invoke Sqlplus

After invoking, go to Task Manager & check the process running.

From the below screenshot, if you can see, we have two Sqlplus Prompts, And from Image its clear that

32 bit version shows as "Oracle SQL*PLUS(32 bit)" and

64 bit version shows as "Oracle SQL*PLUS"

Note : Below Task Manager output is from Windows Server 2012

=====================================================================================================================

#########################################
# 2) Using Registry ( regedit )
#########################################

Go to run and type regedit.

In registry Editor navigate as below,

HKEY_LOCAL_MACHINE --> SOFTWARE --> ORACLE --> KEY_OraHome1 ( If oracle Client Software folder exists in this place then its of 64 bit version )

HKEY_LOCAL_MACHINE --> SOFTWARE --> Wow6432Node --> ORACLE --> KEY_OraHome1 ( If oracle Client Software folder exists in this place then its of 32 bit version )

#########################################
# 2) Modify the parameter in Spfile
#########################################

alter system set "_realfree_heap_pagesize_hint"=262144 scope=spfile sid='*';

Note :

a) As this is RAC environment, we are using sid='*'
b) For Hidden Parameter we are using double quotes (" "), this is not needed for normal parameters

ERROR:  /u01/app/oracle/product/11.2.0.3/linux_x64/agent//install/response//emnoseed.rsp file doesnot exists.

#### Note :

In 11.1.0.1 versions, Agent installation is not possible in GUI mode.

when we try the same in Other platforms of 11.1.0.1 version, OUI will warn that the GUI-based OUI is not a valid option for the 11.1.0.1 Agent installation.

In Linux Platforms, there is a internal BUG due to which this message is not being displayed to user and emnoseed.rsp file doesnot exists error occurs.
