This chapter describes the general process for installing and configuring Oracle Communications Evolved Communications Application Server (OCECAS). Subsequent chapters describe installation steps in detail.
For an overview of OCECAS and an understanding of its concepts and components, see Oracle Communications Evolved Communications Application Server Concepts.
During the installation process, you install and configure the following components:
Oracle database software
Either the Oracle NoSQL database software or the Oracle NoSQL client driver
Java Development Kit (JDK) software
Web browser
The OCECAS software, which includes:
Oracle WebLogic Server, which is the platform container
Oracle Coherence software
Parts of the Oracle Communications Converged Application Server software that are necessary for OCECAS
(Optional) OpenLDAP software
(Optional) Session Border Controller software
(Optional) Core Session Manager software
To view the supported software versions, see "OCECAS System Requirements".
The process of installing the OCECAS software includes the following tasks:
Plan your installation:
Determine the scale of your implementation, for example, a small test system or a large production system
Determine how many physical machines you need, and which software components to install on each machine
Plan the system topology, for example, how the system components connect to each other over the network
Review system requirements, including:
Hardware requirements, such as disk space
System software requirements, such as operating system (OS) versions and OS patch requirements, and Java Virtual Machine (JVM) process requirements (such as memory settings)
Information requirements, such as IP addresses and host names
Perform pre-installation tasks, such as installing the database software and the JDK
Install OCECAS on your machines in the following order:
On the machine that hosts your UDR domain
On the machines that host your runtime domains
On the machine that hosts your management domain
Create your OCECAS database and schema
Configure your OCECAS domains in the following order:
Management domain
Runtime domains
UDR domain
Perform post-installation tasks, such as:
Install the NoSQL database or NoSQL client driver software
Create users for the Session Design Center (SDC) GUI
Perform additional domain configuration tasks
Troubleshoot any installation issues
The OCECAS installation must be performed by qualified personnel. You must be familiar with the software requirements and the operating systems on which you are installing the software.
Follow these guidelines:
As you install each component, such as the JDK, verify that the component installed successfully before continuing the installation process.
Pay close attention to the system requirements. Before you begin installing the software, make sure that your system has the required base software. In addition, make sure that you know all of the required configuration values, such as host names and port numbers.
As you create new configuration values, write them down. In some cases, you need to re-enter configuration values later in the procedure.
Table 1-1 lists placeholders that are used in this guide to refer to the directories that contain OCECAS system components.
Table 1-1 Directory Placeholders
Placeholder | Directory |
---|---|
Central_inventory_location |
The directory in which the Oracle inventory file lives. The Oracle inventory lists all Oracle software installed on a machine. The Oracle installer creates this directory upon the first Oracle product installation. |
DB_Oracle_home |
The directory in which the Oracle database software is installed. |
Domain_home |
The directory in which the OCECAS domain resides (Ocecas_home/user_projects/domains/domain_name). |
Ocecas_home |
The directory in which to install the OCECAS software. This directory is created during product installation. This directory also serves as a repository for common files that are used by Oracle products installed on the same machine. These common files:
|
temp_dir |
A temporary directory into which you download the OCECAS software. |
