Oracle 10g Release 5 Grid Control Installation On Oracle Enterprise Linux (OEL 4.8 64-bit)

In this article I'll describe the installation of Oracle 10g Release 5 (10.2.0.5 64-bit) Grid Control on Oracle Enterprise Linux (OEL 4.8 64-bit). The article is based on a server installation with a minimum of 2G RAM, 4G swap, firewall and secure Linux disabled and the following package groups installed.

• X Window System
• GNOME Desktop Environment
• Editors
• Graphical Internet
• Server Configuration Tools
• Development Tools
• Legacy Software Development
• Administration Tools
• System Tools

The Oracle 10g Grid Control allows you to monitor all aspects of your infrastructure including database and application servers. Like the Oracle9i Management Server it replaces, the grid control requires a database repository. A complete installation includes a repository in a 10g database. It is possible to install the repository in an existing database of a different version, but I try to install the product as it is shipped.

The grid control uses agents on each server to enable monitoring and interaction. As a result, once the grid control is installed it is necessary to install an agent on each server you wish to monitor. The installation of an agent is described in it's owner section. All other tasks relate only to the grid control.

Download Software

Download the following software from here.

• Linux_x86_64_Grid_Control_full_102030_disk1.zip
• Linux_x86_64_Grid_Control_full_102030_disk2.zip
• gc_x86_64_10205_part1of2.zip
• gc_x86_64_10205_part2of2.zip

Notice we've downloaded the base release (10.2.0.3) and the patch (10.2.0.5).

For convenience you may want to download the agent distribution separately. If you are monitoring servers on different platforms the relevant agents must be downloaded.

Unpack Files

First unzip the grid control installation files.

cd /host/software/oracle/GridControlmkdir 10203
cd 10203
unzip ../Linux_x86_64_Grid_Control_full_102030_disk1.zip
unzip ../Linux_x86_64_Grid_Control_full_102030_disk2.zipcd ..
mkdir 10205
cd 10205
unzip ../gc_x86_64_10205_part1of2.zip
unzip ../gc_x86_64_10205_part2of2.zip
unzip p3731593_10205_Linux-x86-64.zip

Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.

<IP-address>  <fully-qualified-machine-name>  <machine-name>

Set Kernel Parameters

Modify the "/etc/sysctl.conf" file to include the lines appropriate to your operating system.

kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
# semaphores: semmsl, semmns, semopm, semmni
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144

Run the following command to change the current kernel parameters.

/sbin/sysctl -p

Add the following entries to the "/etc/security/limits.conf" file.

*               soft    nproc   2047
*               hard    nproc   16384
*               soft    nofile  1024
*               hard    nofile  65536

Append the following entry to the "/etc/pam.d/login" file.

session    required     pam_limits.so

Disable secure linux by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

SELINUX=disabled

Alternatively, this alteration can be done using the GUI tool (Applications > System Settings > Security Level). Click on the SELinux tab and disable the feature.

Setup

Install the required packages, some of which may already be present.

Grid Control Installation (10.2.0.3)

The quickest way to install a fully patched version of the grid control on a clean system is to perform software-only silent install with no configuration steps. First take a copy of the "em_with_new_db.rsp" response file from the "10203" software directory.

cp /host/software/oracle/GridControl/10203/Disk1/response/em_with_new_db.rsp /tmp

Amend the entries in the "/tmp/em_with_new_db.rsp" response file to suit your installation requirements. For this installation I used the following values. All other values in the response file were left unchanged.

UNIX_GROUP_NAME="oinstall"
FROM_LOCATION="/host/software/oracle/GridControl/10203/Disk1/rdbms/Disk1/stage/products.xml"
BASEDIR="/u01/app/oracle/product"
INSTALLATION_NAME="oms10g"
s_gdbName="emrep.localdomain"
s_mountPoint="/u01/app/oracle/oradata"
s_operGroup="dba"
s_adminGroup="dba"
b_emailSelected=true
s_emailAddress="me@example.com"
s_emailServer="localhost"
s_securePassword="oms10gPassword"
s_securePasswordConfirm="oms10gPassword"
b_lockedSelected=false
b_passwordsDifferent=false
b_passwordsSame=true
s_reposPwd="oms10gPassword"
s_reposPwdConfirm="oms10gPassword"

The installation was then started in silent mode using the response file as follows.

$ cd /host/software/oracle/GridControl/10203/Disk1/
$ ./runInstaller -noconfig -ignoreSysPrereqs -silent -responseFile /tmp/em_with_new_db.rsp use_prereq_checker=false

On completion of the installation, the following configuration scripts were run as root.

# /u01/app/oracle/oraInventory/orainstRoot.sh
# cd /u01/app/oracle/product/db10g
# ./allroot.sh

At this point the software installation is complete, but the database and Oracle Management Server (OMS) have not been configured. Before patching, all OMS processes must be stopped using the following command.

$ $OMS_HOME/opmn/bin/opmnctl stopall

Grid Control Patch (10.2.0.5)

Both the Oracle Management Server (OMS) and the Agent are patched separately using variations on the same "patchset.rsp" response file from the "10205" software. Take a copy of the "patchset.rsp" response file.

cp /host/software/oracle/GridControl/10205/3731593/Disk1/response/patchset.rsp /tmp/patchset_oms.rsp

Amend the contents of the "/tmp/patchset_oms.rsp" file, changing only the values listed below. Leave all other values unchanged.

UNIX_GROUP_NAME="oinstall"
FROM_LOCATION="/host/software/oracle/GridControl/10205/3731593/Disk1/stage/products.xml"
ORACLE_HOME="/u01/app/oracle/product/oms10g"
b_softwareonly=true
b_startOMS=false
s_sysPassword="oms10gPassword"
sl_pwdInfo={ "oms10gPassword" }
oracle.iappserver.st_midtier:szl_InstanceInformation={ "oms10gPassword" }

Start the silent installation of the patch software for the OMS with the following command.

$ cd /host/software/oracle/GridControl/10205/3731593/Disk1
$ ./runInstaller -noconfig -silent -responseFile /tmp/patchset_oms.rsp

Once the installation is complete, run the configuration script as the root user.

# cd /u01/app/oracle/product/oms10g
# ./root.sh

This script does not produce any output.

To patch the Agent, copy the "patchset_oms.rsp" file.

cp /tmp/patchset_oms.rsp /tmp/patchset_agent.rsp

Only the following value needs to be changed in the "/tmp/patchset_agent.rsp". All other settings match those for the OMS patch.

ORACLE_HOME="/u01/app/oracle/product/agent10g"

Start the silent installation of the patch software for the Agent with the following command.

$ cd /host/software/oracle/GridControl/10205/3731593/Disk1
$ ./runInstaller -noconfig -silent -responseFile /tmp/patchset_agent.rsp

Once the installation is complete, run the configuration script as the root user.

# cd /u01/app/oracle/product/agent10g
# ./root.sh

Configure Grid Control

Assuming all the installations and patches have completed with no errors we can now configure the database and the OMS.

Configure the database using the following command.

$ cd $ORACLE_HOME/oui/bin
$ ./runConfig.sh ORACLE_HOME=/u01/app/oracle/product/db10g ACTION=configure MODE=perform

Once the database is configured, issue the following command to configure the OMS.

$ export PERL5LIB=$OMS_HOME/perl/lib/5.6.1
$ $OMS_HOME/perl/bin/perl $OMS_HOME/sysman/install/ConfigureGC.pl /u01/app/oracle/product

Both configuration steps can take quite some time, so be patient.

The OMS configuration includes configuration of the Agent. The last part of this configuration is an attempt to start the Agent. If the agent fails to start with a timezone error, enter the correct value for the "agentTZRegion" parameter in the "$AGENT_HOME/sysman/config/emd.properties" file, delete the following files and start the agent.

$ rm -r $AGENT_HOME/sysman/emd/state/*
$ rm -r $AGENT_HOME/sysman/emd/collection/*
$ rm -r $AGENT_HOME/sysman/emd/upload/*
$ rm $AGENT_HOME/sysman/emd/lastupld.xml
$ rm $AGENT_HOME/sysman/emd/agntstmp.txt
$
$ $AGENT_HOME/bin/emctl start agent

The Grid control is now configured.

Check the Status of the Grid Control

The following command checks the status of the OMS.

$ $OMS_HOME/bin/emctl status oms
Oracle Enterprise Manager 10g Release 5 Grid Control

To access the grid control, use the URL specified in the "$OMS_HOME/sysman/setupinfo.txt" file. In my case the URL is shown below.

https://grid.localdomain:1159/em

Starting and Stopping Grid Control Services

The following script shows how the whole grid control is started and stopped.

# Start everything
$ORACLE_HOME/bin/dbstart $ORACLE_HOME
$OMS_HOME/opmn/bin/opmnctl startall
$AGENT_HOME/bin/emctl start agent# Stop everything
$AGENT_HOME/bin/emctl stop agent
$OMS_HOME/opmn/bin/opmnctl stopall
$ORACLE_HOME/bin/dbshut $ORACLE_HOME

The dbstart and dbshut commands require the "/etc/oratab" file to be editied to allow auto startup/shutdown.

By default, the database supporting the repository is in NOARCHIVELOG mode.
