This post explains how to install WebSphere Application Server 8.5.5 with the Java SDK 7.

What you need

Here are the parts you need to download to install WAS 8.5.5 with Java 7

Pre-requisites

For the installer to work, you need the following libraries:

• ld-linux.so.2
• libgcc_s.so.1

You can install them with the following command:

yum install -y ld-linux.so.2 libgcc_s.so.1

You also need unzip to unzip the binaries:

yum install -y unzip

And finally for WAS to be able to start, it has to know its own name, like often with IBM softwares, so set it properly:

NAME=YourHostnameHere

sed -i "s/HOSTNAME=.*$/HOSTNAME=$NAME/g" /etc/sysconfig/network
hostname $NAME
sed -i "s/localhost4\slocalhost4.localdomain4\s*$/localhost4 localhost4.localdomain4 $NAME/g" /etc/hosts
sed -i "s/localhost6\slocalhost6.localdomain6\s*$/localhost6 localhost6.localdomain6 $NAME/g" /etc/hosts
echo $NAME > /etc/HOSTNAME

Install Installation Manager

Installation manager is required to install WebSphere and the SDK 7. First, unzip the binaries:

mkdir im
unzip InstalMgr1.6.2_LNX_X86_WAS_8.5.5.zip -d im
cd im

Then a few tweaks for the silent install:

echo -Xss512k >> silent-install.ini
echo -Xmso64k >> silent-install.ini
echo >> silent-install.ini

And finally, install Installation Manager

./installc -log log.log -acceptLicense

Install WebSphere Application Manager 8.5.5

WebSphere comes as an Installation Manager Repository. There is no installer bundled in the repository, that’s why we have to use IM.

First, unzip the three zip in the same folder:

mkdir was
unzip WAS_V8.5.5_*.zip -d was

Then, FYI, you can check the available sofware in the repository:

/opt/IBM/InstallationManager/eclipse/tools/imcl listAvailablePackages -repositories was

It should print com.ibm.websphere.BASE.v85_8.5.5000.20130514_1044.

Install WAS:

/opt/IBM/InstallationManager/eclipse/tools/imcl install com.ibm.websphere.BASE.v85_8.5.5000.20130514_1044 -repositories was -acceptLicense

And create a profile:

/opt/IBM/WebSphere/AppServer/bin/manageprofiles.sh -create -templatePath /opt/IBM/WebSphere/AppServer/profileTemplates/default -hostName master1 -cellName cell1 -nodeName node1 -serverName server1

Install Java 7 for WAS

Unzip the three zips:

mkdir sdk
unzip WS_SDK_JAVA_TEV7.0_*.zip -d sdk

Then, FYI, you can check the available sofware in the repository:

/opt/IBM/InstallationManager/eclipse/tools/imcl listAvailablePackages -repositories sdk

It should print com.ibm.websphere.IBMJAVA.v70_7.0.1000.20120424_1539.

Install the SDK. Notice the new parameter to install into the WAS folder. Without this it will say required packages are missing:

/opt/IBM/InstallationManager/eclipse/tools/imcl install com.ibm.websphere.IBMJAVA.v70_7.0.1000.20120424_1539 -repositories /sdk -acceptLicense -installationDirectory /opt/IBM/WebSphere/AppServer

Finally, activate the SDK 7 for all your profiles and start the WAS server:

/opt/IBM/WebSphere/AppServer/bin/managesdk.sh -enableProfileAll -sdkName 1.7_64
/opt/IBM/WebSphere/AppServer/bin/startServer.sh -profileName AppSrv01 server1

You can enable the SDK 7 only for one profile by doing:

/opt/IBM/WebSphere/AppServer/bin/managesdk.sh -enableProfile -profileName profile_name -sdkName 1.7_64

Default profile_name is AppSrv01.

You can clean and save space by deleting the was and sdk folders if you want to.
