Assumptions
This article assumes you have an existing server (real or virtual) with either Oracle Linux 6.x or 7.x installed on it. For instruction on how to do this check out the following articles.
I picked the "Desktop" option for the OL6 installation and the "Server with GUI" option for OL7, so I would have a graphical interface without having to select separate package groups. Everything in the installation will be 64-bit.
Software
Download the Weblogic Server 12c software from Oracle Technology Network.
- Java Development Kit (I used 8u144 jdk-8u144-linux-x64.tar.gz)
- Fusion Middleware Infrastructure Installer (1.4G)
Remember, you will need the infrastructure version of WebLogic if you plan to do an Oracle Forms and Reports Services installation.
Setup
The following actions should be performed by the "root" user.
Make sure the "/etc/hosts" file contains correct entries for both the "localhost" and real host names.
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 192.168.56.133 ol6.localdomain ol6
Create a new group and user.
groupadd -g 54321 oinstall useradd -u 54321 -g oinstall oracle passwd oracle
Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/12.2.1 mkdir -p /u01/app/oracle/config/domains mkdir -p /u01/app/oracle/config/applications chown -R oracle:oinstall /u01 chmod -R 775 /u01/
Append the following entries into the "/home/oracle/.bash_profile" file.
# Adjust paths as required. export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/12.2.1 export MW_HOME=$ORACLE_HOME export WLS_HOME=$MW_HOME/wlserver export WL_HOME=$WLS_HOME export DOMAIN_BASE=$ORACLE_BASE/config/domains export DOMAIN_HOME=$DOMAIN_BASE/mydomain export JAVA_HOME=/u01/app/oracle/jdk1.8.0_144 export PATH=$JAVA_HOME/bin:$PATH
Install the JDK.
# su - oracle $ cd $ORACLE_BASE $ tar -xvzf /tmp/jdk-8u144-linux-x64.gz
For Oracle Linux 6, as specified in MOS Note [ID 1487773.1], amend the "/etc/security/limits.d/90-nproc.conf" file, making the following change.
# From * soft nproc 1024 #To * - nproc 16384
Installation
The images were originally captured from a 12.2.1.0 installation. The process is the same for 12.2.1.2.
Run the installer as the "oracle" user.
$ unzip fmw_12.2.1.2.0_infrastructure_Disk1_1of1.zip $ $JAVA_HOME/bin/java -jar fmw_12.2.1.2.0_infrastructure.jar
If this is is the first installation on the machine you will need to specify an inventory location. Enter the inventory location, like "/u01/app/oraInventory" and click the "OK" button.
Click the "Next" button on the welcome screen.
Select the "Skip Auto Updates" options, then click the "next" button.
Enter the middleware home ("/u01/app/oracle/product/12.2.1") and click the "Next" button.
Accept the "Fusion Middleware Infrastructure" option by clicking the "Next" button.
Wait for the prerequisite checks to complete. If there are failures, correct them and rerun the checks. If there are no failures, click the "Next" button.
Either enter your support details, or uncheck the security updates checkbox. Click the "Next" button. If you chose not to receive security updates, click the "Yes" button on the warning dialog.
If you are happy with the summary information, click the "Install" button.
Wait for the installation to complete, then click the "Next" button.
On the installation complete screen, click the "Finish" button to launch the Configuration Wizard.
If you are doing an installation for Oracle Forms and Reports Services, you don't need to create the domain at this point, so stop here.
Create Domain
Launch the Configuration Wizard with the following command.
$ $ORACLE_HOME/oracle_common/common/bin/config.sh
Accept the "Create a new domain" option, enter the domain name at the end of the "Domain Location", then click the "Next" button. In this case my domain was called "mydomain", so the path I used was "/u01/app/oracle/config/domains/mydomain".
Select the required product template and click the "Next" button.
Enter the administrator credentials and click the "Next" button.
Enter the domain mode and JDK details, then click the "Next" button.
Select any required advanced configuration options. For this example I ignored the advanced configuration. Click the "Next" button.
If you are happy with the configuration summary screen, click the "Create" button.
Once the domain is created, click the "Next" button.
Make a note of the Admin Server URL and click the "Finish" button.
Post-Installation
If you chose the "Production Mode" options for the domain, you will need to create a "boot.properties" file for the scripts referred to later to work without credentials. Adjust the DOMAIN_HOME and credentials appropriately.
$ export DOMAIN_HOME=$ORACLE_BASE/config/domains/mydomain $ mkdir -p $DOMAIN_HOME/servers/AdminServer/security $ echo "username=weblogic" > $DOMAIN_HOME/servers/AdminServer/security/boot.properties $ echo "password=Password1" >> $DOMAIN_HOME/servers/AdminServer/security/boot.properties
The "$ORACLE_BASE/config/domains/mydomain" directory now contains a script that can be used to start the server. Remember to use the "&" if you want access to the commandline to be returned.
$ $DOMAIN_HOME/startWebLogic.sh &
Once the server is started you can access the administrator console using the "http://hostname:port/console" URL. Log in using the username and password provided in the previous step.
The following scripts are useful.
$ # Start NodeManager (if you configured one-per-domain) $ nohup $DOMAIN_HOME/bin/startNodeManager.sh > /dev/null 2>&1 & $ # Start WebLogic $ nohup $DOMAIN_HOME/startWebLogic.sh > /dev/null 2>&1 & $ # or $ nohup $DOMAIN_HOME/bin/startWebLogic.sh > /dev/null 2>&1 & $ # Stop WebLogic $ $DOMAIN_HOME/bin/stopWebLogic.sh $ # Start Managed Server $ nohup $DOMAIN_HOME/bin/startManagedWebLogic.sh AdminServer > /dev/null 2>&1 & $ # Stop Managed Server $ $DOMAIN_HOME/bin/stopManagedWebLogic.sh AdminServer $ # Start the configuration wizard $ $WLS_HOME/common/bin/config.sh
Patching WebLogic Server
Applying patches to WebLogic Server 12c is done using the OPatch utility. Make sure any processes running under this WebLogic installation are stopped before applying a patch.
Download the latest version of OPatch and the WebLogic updates from Oracle Support and put them into the "/u01/software" directory with the other software. For example.
- OPatch : p6880880_132000_Generic.zip *** See Note Below
- Updates : p22331568_122100_Generic.zip
At the time of writing, the latest version of OPatch (OUI NextGen 13.2) is older than the version of OPatch that ships with WebLogic Server 12.2.1.
Assuming a newer version of OPatch were available you would unzip the OPatch utility and add it to your path.
cd /u01/software unzip p6880880_132000_Generic.zip export PATH=/u01/software/OPatch:$PATH
Since there isn't a newer version available at the time of writing, we will use the existing one.
export PATH=$MW_HOME/OPatch:$PATH
Unzip the patch and change to the resulting directory, then apply the patch.
unzip -d PATCH_TOP p22331568_122100_Generic.zip cd PATCH_TOP/22331568 export ORACLE_HOME=$MW_HOME opatch apply
Answer any prompts and take appropriate action when required.
When the patch is complete, check the WebLogic version using the following command. Depending on the scale of the patch, the version may not have changed.
. $WLS_HOME/server/bin/setWLSEnv.sh java weblogic.version
