Required packages for Oracle 11g RDBMS install on LINUX

Leave a comment

The installation of Oracle RDBMS software requires supporting OS level functionality to successfully complete and operate. This article outlines the RPM checks which should be completed before the installation of Oracle 11g RDBMS is begun.

1. Logon to your Linux Server as the root user.

2. Below is a listing of the RPM Oracle gives as required for a successful 11g RDBMS install. However, RPMs are continuously updated so the version on your system may be newer than what was given by the manufacturer

binutils-2.17.50.0.6
compat-libstdc++-33-3.2.3
elfutils-libelf-0.125
elfutils-libelf-devel-0.125
elfutils-libelf-devel-static-0.125
gcc-4.1.2
gcc-c++-4.1.2
glibc-2.5-24
glibc-common-2.5
glibc-devel-2.5
glibc-headers-2.5
kernel-headers-2.6.18
ksh-20060214
libaio-0.3.106
libaio-devel-0.3.106
libgcc-4.1.2
libgomp-4.1.2
libstdc++-4.1.2
libstdc++-devel-4.1.2
make-3.81
numactl-devel-0.9.8.i386
sysstat-7.0.2
unixODBC-2.2.11
unixODBC-devel-2.2.11

3. Thus, when investigating if the RPM exists on your system, you should not include the version number. In this example we will check for the existence of RPM binutils-2.17.50.0.6. Use the rpm –qa command to gather all installed packages, then lookup for the specific one with grep.


[root@mylinux1 ~]# rpm -qa|grep binutils
binutils-2.17.50.0.6-14.el5
[root@mylinux1 ~]#

4. As seen above the actual version of the rpm binutils-2.17.50.0.6 is an exact match, but it does not have to be. As long as the installed package has a version greater than the required version of 2.17.50.0.6, it meets our needs for 11g RDBMS install.

5. Repeat these steps for each required package.
This completes checking for required Oracle 11g RDBMS packages.

Required packages for Oracle 10g RDBMS install on LINUX

Leave a comment

The installation of Oracle RDBMS software requires supporting OS level functionality to successfully complete and operate. This article outlines the check which should be done before the installation of Oracle 10g RDBMS is begun.

1. Logon to your Linux Server as the root user.

2. Below is a listing of the RPMs Oracle gives as required for a successful 10g RDBMS install. However, RPMs are continuously updated so the version on your system may be newer than shown below.

sysstat-7.0.2-1.el5.x86_64.rpm
glibc-devel-2.5-24.x86_64.rpm

compat-gcc-34-c++-3.4.6-4.x86_64.rpm
gdb-6.5-37.el5.x86_64.rpm
libtermcap-devel-2.0.8-46.1.x86_64.rpm

unixODBC-devel-2.2.11-7.1.i386.rpm
libaio-devel-0.3.106-3.2.i386.rpm

3. When investigating if the RPM exists on your system, you should not include the version number. In this example we will check for the existence of RPM libgomp-4.1.2-42.el5.x86_64.rpm. Use the rpm –qa command to gather all installed packages, then lookup the specific one with grep.

[root@mylinux1 ~]# rpm -qa|grep libgomp
libgomp-4.4.4-13.el5
[root@mylinux1 ~]#

4. As seen above the actual version of the rpm libgomp is 4.4.4 which is greater than the required version of 4.1.2 and meets our needs for 10g RDBMS install.

5. Repeat these steps for each required package.

This completes checking for required Oracle 10g RDBMS packages.

Configuration of OCFS2 in LINUX

Leave a comment

OCFS2 Oracle Cluster File System version 2 is a file system which allows for multiple machines to open the same files at the same time without corruption. This file system can be used for multiple reasons but is mostly seen in Oracle RAC systems. This article details the configuration of OCFS2 after the RPMs have been installed on your OS.

1. Logon to your Linux server as root.

2. Create the directory /etc/ocfs2 to house your oracle cluster.conf file. This file will contain the name of your cluster and all nodes with in that cluster.

[root@mylinux1 etc]# mkdir /etc/ocfs2
[root@mylinux1 etc]# chmod 775 /etc/ocfs2

3. Edit the file cluster.conf and enter the strings similar to below; changing the value of ip_address, name and cluster to values which are correct for your installation..

[root@mylinux1 etc]# vi /etc/ocfs2/cluster.conf

node:
ip_port = 7777
ip_address = 204.34.132.38
number = 0
name = mylinux1.mydomain.com
cluster = myrac

node:
ip_port = 7777
ip_address = 204.34.132.39
number = 1
name = mylinux2.mydomain.com
cluster = myrac

cluster:
node_count = 2
name = myrac

4. Configure the ocfs2 installed on each node of the RAC with the o2cb configure command. NOTE: Enter the following:


Load O2CB driver on boot (y/n) [y] = y
Cluster stack backing O2CB [o2cb] = o2cb
Cluster to start on boot (Enter “none” to clear) [ocfs2]: = name of the cluster in cluster.conf file for this example it is myrac
Specify heartbeat dead threshold (>=7) [31] = 31
Specify network idle timeout in ms (>=5000) [30000] = 30000
Specify network keepalive delay in ms (>=1000) [2000] = 2000
Specify network reconnect delay in ms (>=2000) [2000] = 2000

Example:
[root@mylinux1 etc]# /etc/init.d/o2cb configure
Configuring the O2CB driver.

This will configure the on-boot properties of the O2CB driver.
The following questions will determine whether the driver is loaded on
boot. The current values will be shown in brackets (‘[]’). Hitting
without typing an answer will keep that current value. Ctrl-C
will abort.

Load O2CB driver on boot (y/n) [y]:
Cluster stack backing O2CB [o2cb]:
Cluster to start on boot (Enter “none” to clear) [ocfs2]: myrac
Specify heartbeat dead threshold (>=7) [31]:
Specify network idle timeout in ms (>=5000) [30000]:
Specify network keepalive delay in ms (>=1000) [2000]:
Specify network reconnect delay in ms (>=2000) [2000]:
Writing O2CB configuration: OK
Starting O2CB cluster myrac: OK
[root@mylinux1 etc]#

[root@mylinux2 etc]# /etc/init.d/o2cb configure
Configuring the O2CB driver.

This will configure the on-boot properties of the O2CB driver.
The following questions will determine whether the driver is loaded on
boot. The current values will be shown in brackets (‘[]’). Hitting
without typing an answer will keep that current value. Ctrl-C
will abort.

Load O2CB driver on boot (y/n) [n]: y
Cluster stack backing O2CB [o2cb]:
Cluster to start on boot (Enter “none” to clear) [ocfs2]: myrac
Specify heartbeat dead threshold (>=7) [31]:
Specify network idle timeout in ms (>=5000) [30000]:
Specify network keepalive delay in ms (>=1000) [2000]:
Specify network reconnect delay in ms (>=2000) [2000]:
Writing O2CB configuration: OK
Loading filesystem “configfs”: OK
Mounting configfs filesystem at /sys/kernel/config: OK
Loading filesystem “ocfs2_dlmfs”: OK
Creating directory ‘/dlm’: OK
Mounting ocfs2_dlmfs filesystem at /dlm: OK
Starting O2CB cluster myrac: OK
[root@mylinux2 etc]#


This completes configuration of OCFS2 for Oracle RAC.

Download and Installation of OCFS2 RPMs for Linux

Leave a comment

Oracle Cluster File System 2 (OCFS2) is a file system which allows for multiple hosts to access the same files on a shared storage at the same time. This type of access is required for deployment of an Oracle RAC system. In this article we will cover the procedure to download and install the RPMs for OCFS2 to support shared storage on an Oracle RAC system.

1. Determine the current Kernel installed on all RAC nodes. NOTE: The kernels must be the same on every RAC node.

NODE 1:
[root@mylinux1 etc]# uname -r
2.6.18-194.32.1.el5
[root@mylinux1 etc]#

NODE2:
[root@mylinux2 ~]# uname -r
2.6.18-194.32.1.el5
[root@mylinux2 ~]#

2. Go to the URL: http://oss.oracle.com/projects/ocfs2/ , select the download tab and navigate to the correct rpm download for your kernel.

2.6.18-194.32.1.el5
2011.01.20
Packages for RHEL5 2.6.18-194.32.1.el5

3. Go to the URL: http://oss.oracle.com/projects/ocfs2-tools/, select the download tab and navigate to the correct rpm downloads for your OS. Example for this OS we download the following files:

ocfs2-tools-1.4.4-1.el5.x86_64.rpm
2010.04.19 7a2f59a05f2cf1bea24dc04f34b09371
OCFS2 tools
ocfs2-tools-debuginfo-1.4.4-1.el5.x86_64.rpm
2010.04.19 91d6e65e902dedcd28e8e4f2d9fb4271
OCFS2 tools debuginfo
ocfs2-tools-devel-1.4.4-1.el5.x86_64.rpm
2010.04.19 2e47beaab89ebba8b1d276fb894184d5
OCFS2 tools libraries/header
ocfs2console-1.4.4-1.el5.x86_64.rpm
2010.04.19 78ccf0cf8564a6d5b48d534c7f3a07bc

4. Once the download completes transfer all the files to all nodes in the cluster. It is best at this point to create a temporary directory under /tmp, to store your files with the following command.

[root@mylinux1 tmp]# mkdir oracle_tmp
[root@mylinux1 tmp]# chmod 777 oracle_tmp
[root@mylinux1 tmp]#

5. Once the files are in location, logon as root and install using the rpm command on all nodes of the RAC.

rpm -Uvh ocfs2-tools-1.4.4-1.el5.x86_64.rpm
rpm -Uvh ocfs2-2.6.18-194.32.1.el5-1.4.7-1.el5.x86_64.rpm
rpm –Uvh ocfs2console-1.4.4-1.el5.x86_64.rpm

[root@mylinux1 oracle_tmp]# rpm -Uvh ocfs2-tools-1.4.4-1.el5.x86_64.rpm

[root@mylinux1 oracle_tmp]#

This completes the download and installation of OCFS2 on Linux to support an Oracle RAC system.
