Using This Document with the Certification Matrix and Product Installation Guides
This document is intended for use in conjunction with the Oracle WebLogic Server and Coherence installation guides and the Oracle Fusion Middleware 14c Certifications.
Consider the following pre-installation workflow:
- Task 1 Find Out What is Certified
-
The Oracle Fusion Middleware 14c Certifications can be found in the table on the Oracle Fusion Middleware Supported System Configurations page. Find the
.xls
document that includes your products.Oracle has tested and verified the performance of your product on all certified systems and environments; whenever new certifications occur, they are added to the proper certification document right away. New certifications can occur at any time, and for this reason the certification documents are kept outside of the documentation libraries and are available on Oracle Technology Network.
If you use My Oracle Support, you can reference My Oracle Support Certifications, which is a self-service certification application which provides a structured display of most common certification data. Go tohttp://support.oracle.com/
and refer to the Certifications tab. - Task 2 Verify the Requirements of the Certification
-
This document should be used to verify that the requirements of the certification are met. For example, if the certification document indicates that your product is certified for installation on Oracle Linux 7, this document should be used to verify that your Oracle Linux 7 system has met the required minimum specifications, such as disk space, available memory, specific platform packages and patches, and other operating system-specific items.
- Task 3 Install Your Software
-
After you have verified that your environment meets the requirements specified in both the certification and system requirements documents, you are ready to begin your installation.
Your product installation guides contain the step-by-step instructions to get your product physically installed and configured on your system. These guides are available only from the Oracle WebLogic Server and Coherence 14.1.1.0.0 documentation library. Both the certification and system requirement documents can be updated multiple times in between product releases, depending on whether or not new information is available.

Processor Requirements
Oracle WebLogic Server and Coherence requires a minimum 1-GHz CPU.
Parent topic: System Requirements and Specifications
Java Development Kit (JDK) Requirements
To run installers in the 14c (14.1.1.0.0), you must have a certified JDK already installed on your system. For information about the latest certified JDKs, refer to the certification document for your software version listed in Oracle Fusion Middleware Supported System Configurations page.
Note:
It is recommended that you install the JDK version used by Oracle Fusion Middleware products in a separate location from the default JDK installation on the system, so that the JDK version used by Oracle Fusion Middleware products can be managed and maintained with the Fusion Middleware products.Parent topic: System Requirements and Specifications

Minimum Memory Requirement for Installing Oracle WebLogic Server and Coherence
Unless otherwise noted, Table 1-1 lists the general minimum memory requirements for installing Oracle Weblogic Server and Coherence.
Note:
For the purposes of this document, memory requirements fall into two categories: physical memory (the amount of physical RAM installed on host) and the minimum available memory, which includes swap space in addition to the physical memory.
The memory requirements listed here are minimum requirements. The actual required memory will vary, depending upon the number of Managed Servers and the number of Oracle Fusion Middleware products you configure in the domains on each host. For some guidelines about determining the amount of memory required for a specific deployment, see Using a Formula to Determine Memory Requirements for a Specific Deployment.
If you plan to install and configure a database instance on the same server, you should add at least an additional 2 GB of physical and 2 GB of available memory. For more information about memory requirements for the database, see the documentation for your version of the database software.

Operating System | Minimum Physical Memory Required | Minimum Available Memory Required |
---|---|---|
Linux |

Parent topic: General Memory Requirements
Using a Formula to Determine Memory Requirements for a Specific Deployment
Oracle Fusion Middleware installations vary widely in terms of how the Oracle WebLogic Server domains that support them are configured. For example, in some highly available production environments, you might have several Managed Servers running on each host. On the other hand, a single Administration Server is adequate for some development purposes.
To estimate the amount of required memory to run the Oracle WebLogic Server and Coherence in a particular deployment configuration, you can consider the amount of memory required by the operating system and other software, and then add a set amount of memory that will be required for each Java Virtual Machine (JVM) that you plan to configure on the host. Each Managed Server configured in a domain represents a single JVM instance.
Note:
Oracle recommends that for the performance of well-scaled production environments, the total Java heap memory allocations for all the Managed Servers per host add up to no more than 50% of the total physical memory on the host. If larger JVM heap sizes are required, or more managed servers are needed, physical memory should be increased accordingly.
In general, you can use the following formula as a general guideline to predict the minimum available memory requirements for Oracle WebLogic Server and Coherence:
3 GB of available memory for the operating system and other software + 3 GB of available memory for each Managed Server ----------------------------------------------------- Total required available memory
It is important to note that this is a general guideline and the actual memory required for the operating system or a specific Managed Server can vary widely, depending on the resources and services targeted to the host or to the Managed Server.
Parent topic: General Memory Requirements
Example: Determining Memory Requirements for a Development Environment
When determining memory required for a development environment, consider the type of domain you are using to test your applications.
If you are using an Administration Server for your development system you can use the general formula in Using a Formula to Determine Memory Requirements for a Specific Deployment as a guideline to determine the initial memory requirements.
For example:
3 GB for the operating system and other software + 3 GB for the Administration Server ------------------------------------- 6 GB of available memory
Parent topic: General Memory Requirements
Example: Determining Memory Requirements for a Production Environment
In a production environment, Oracle recommends as a best practice that you target products and services to specific Managed Servers and clusters, based on the resources required by the products and services.
For example, if you are planning to configure a Oracle WebLogic Server domain with an Administration Server and two Managed Servers, then you could use the following formula to determine the minimum required available memory:
3 GB for the operating system and other software 3 GB for the Admin Server + 6 GB for the two Managed Servers -------------------------------------- 12 GB
Parent topic: General Memory Requirements
Considering the Impact of Open File and Process Limits on Memory Requirements
When determining the memory requirements for a production environment, you should also take into account other operating system settings, including the number of file descriptors (open files) allowed per process and the number of processes required for each product or service that is targeted to a Managed Server.
For information about the recommended minimum open file and process limits for Oracle Fusion Middleware, see Setting the Open File Limit and Number of Processes Settings on UNIX Systems.
Parent topic: General Memory Requirements
Temporary Disk Space Requirements
The installation program uses a temporary directory into which it extracts the files that are needed to install the software on the target system. During the installation process, your temporary directory must contain sufficient space to accommodate the compressed Java Run-time Environment (JRE) bundled with the installation program and an uncompressed copy of the JRE that is expanded into the temporary directory. The extracted files are deleted from the temporary directory after the installation process. The files in the temporary directory require approximately 2.5 times the space that is ultimately required for the installation.
By default, the installation program uses the following temporary directories:
-
Windows platforms—directory referenced by the
TMP
system variable -
UNIX platforms—system-dependent temporary directory
Note:
If you do not have enough temporary space to run the installation program, you are prompted to specify an alternate directory or exit the installation program.
To make sure that you have adequate temporary space, you may want to allocate an alternate directory for this purpose by doing one of the following (depending on your operating system:
-
On Windows operating systems, set the
TMP
system variable to a directory of your choice. -
Run the installation program from the command line and include the
-Djava.io.tmpdir=
tmpdirpath
option, replacingtmpdirpath
with the full path of the directory you want to designate as a temporary storage area for the installation program.While running the Oracle WebLogic Server installer for Windows, run the following command:
java -Djava.io.tmpdir=C:\Temp -jar fmw_14.1.1.0.0_wls.jar

Network Requirements
Typically, the computer on which you want to install Oracle WebLogic Server and Coherence is connected to the network.
This section describes how to install Oracle Database on computers that do not meet the typical scenario. It describes the following cases:
- Guidelines for a Correct Format of Entries in the /etc/hosts File
- Understanding IPv6 and Oracle Weblogic Server and Coherence
- Configuration Requirements for Installing on a Non-Networked Computer
Parent topic: System Requirements and Specifications
Guidelines for a Correct Format of Entries in the /etc/hosts File
To ensure that both forward lookup (find the IP address given the hostname) and reverse lookup (finding the hostname given the IP address) return the same results, make sure your /etc/hosts
file is formatted correctly using the following guidelines:
-
The host name may contain only alphanumeric characters, hyphen, and period. The name must begin with an alphabetic character and end with an alphanumeric character.
-
Host names should be specified as fully qualified host names (host name with the appended domain name).
-
Lines cannot start with a blank space or tab character, but fields may be separated by any number of space or tab characters.
-
Comments are allowed and designated by a pound sign (#) preceding the comment text.
-
Trailing blank and tab characters are allowed.
-
Blank line entries are allowed.
-
Only one host entry per line is allowed.
For example: 11.111.11.11 server.example.com server

Enabling Unicode Support
Your operating system configuration can influence the behavior of characters supported by Oracle WebLogic Server and Coherence.
On UNIX operating systems, Oracle highly recommends that you enable Unicode support by setting the LANG
and LC_ALL
environment variables to a locale with the UTF-8 character set. This enables the operating system to process any character in Unicode. Table 1-3 describes these environment variables.

Variable | Description |
---|---|
|
This environment variable sets the installation default locale. For example:
|
|
This environment variable overrides the value of the
|
To check your current locale settings, use the locale
command on your system. Below is an example:
locale LANG=en_US.UTF-8 LC_CTYPE=en_US.UTF-8 LC_NUMERIC=en_US.UTF-8 LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 LC_MONETARY=en_US.UTF-8 LC_MESSAGES= LC_PAPER="POSIX" LC_NAME="POSIX" LC_ADDRESS="POSIX" LC_TELEPHONE="POSIX" LC_MEASUREMENT="POSIX" LC_IDENTIFICATION="POSIX" LC_ALL=
In a design-time environment, if you are using Oracle JDeveloper, select Tools -> Preferences -> Environment -> Encoding -> UTF-8 to enable Unicode support.
