Oracle WebLogic Server 12.2.1.4.0 Slim Installer

Posted by Dirk Nachbar on Monday, February 03, 2020 with 2 comments
Since WebLogic Server 12.2.1.4.0 you have a new edition of the Oracle WebLogic Server, it's the Slim Installer. The corresponding software you can download under:

https://www.oracle.com/middleware/technologies/weblogic-server-installers-downloads.html



The Slim Installer is much smaller than the Generic or the Fusion Middleware Infrastructure Installers.
  • WebLogic Generic Installer: 826 MB
  • Fusion Middleware Infrastructure Installer: 1.5 GB
  • WebLogic Slim Installer: 182 MB
Basically the Slim Installer is a full WebLogic Server, but without any examples, no WebLogic Console, no WebLogic Clients, no Maven Plugin and no Java DB.

The installation comes without any graphical installer, its pure command line. So be aware of the command line option for the invoking of the Slim Installer.
In case you will start the Slim Installer, as you are used to the Generic Installer, just with "java -jar fmw_12.2.1.4.0_wls_quick_slim.jar", the installer will install the WebLogic Slim Edition in your present work directory/wls12214 and the corresponding Oracle Inventory will be created under $HOME/oraInventory.

As you can see from above listing, the ORACLE_HOME location for the new installation is chosen automatically with my present work directory/wls122140 and the Oracle Inventory goes into $HOME/oraInventory.

Second trial, this time with the command line option "java -jar fmw_12.2.1.4.0_wls_quick_slim.jar ORACLE_HOME=$ORACLE_HOME"

This looks a bit better now, our target installation directory is now under our desired £ORACLE_HOME, but the Oracle Inventory is still under $HOME/oraInventory.

3rd attempt, now with the command line option "java -jar fmw_12.2.1.4.0_wls_quick_slim.jar ORACLE_HOME=$ORACLE_HOME -invPtrLoc /u00/app/oracle/install/oraInst.loc" and a prepare oraInst.loc file in which we define the Oracle Inventory location and the group ownership for the Oracle Inventory.

#

The installation of Oracle Fusion Middleware 12c WebLogic and Coherence Developer Slim 12.2.1.4.0 completed successfully.

This time everything is located and installed as we want :-)

Now lets compare the space usage between the Oracle WebLogic Generic, Fusion Middleware Infrastructure and the WebLogic Slim:

#
[oracle@wlstest] cd /u00/app/oracle/product
[oracle@wlstest] du -sh fmw*
2.1G fmw-infra-12.2.1.4.0
1.1G fmw-wls-12.2.1.4.0
452M fmw-wls-slim-12.2.1.4.0

As you can see, the WebLogic Generic (fmw-wls-12.2.1.4.0) needs 1.1 GB disk space, the Fusion Middleware Infrastructure (fmw-infra-12.2.1.4.0) needs 2.1 GB and the WebLogic Slim (fmw-wls-slim-12.2.1.4.0) just needs 452 MB (more than half lesser than the Generic Installer and more than 4 times lesser than the Fusion Middleware Infrastructure Installer).

Specially when you will use the WebLogic Slim Installer in a Docker Image, you will gain a lot of disk savings.

After you have installed the WebLogic Slim Installer you can as normal startup the $ORACLE_HOME/oracle_common/common/bin/config.sh to configure and create your WebLogic Domain with the graphical wizard, but be aware, you dont have any WebLogic Console (http://<servername>:<AdminServerPort>/console) afterwards. Everything you need to configure, you will have to do it through wlst or via RESTful Management API.
