2 System Requirements

This chapter describes the hardware and software requirements for Oracle Communications Service Broker.

Hardware Requirements

This section describes the hardware requirements for Service Broker.

Managed Servers

You can deploy managed servers on the following CPU architectures:

• x86 64-bit

• Oracle SPARC 64-bit

Each server should have redundant network interface cards.

The following are recommendations for each physical server in a production system. These are guidelines only:

• Dual quad core processors with 16 GB of RAM

• 2 GB of free disk space for the installation

The following requirements apply to specific managed server tiers:

• Processing servers:

  Extra disk space is required for processing servers if you store Service Data Records (SDRs) in files on the server. In general, 10 GB is sufficient for handling SDRs. However, the actual disk space you need depends on the server's capacity, the amount of traffic, and how many SDR files are stored on the server.

  See information about configuring SDR logging in Oracle Communications Service Broker System Administrator's Guide.

• Signaling servers:

  A Dialogic TDM signaling board and Dialogic software are required for signaling servers that run in a TDM-based network.

  See "Installing Dialogic Hardware and Software for TDM Networks" for more information.

Administration Server

The Administration Server can be installed on the same physical server as the managed servers; however, Oracle recommends that you install it on its own physical server.

You can deploy the Administration Server on the following CPU architectures:

• x86 64-bit

• Oracle Sun SPARC 64-bit

The following are recommendations for each physical computer that hosts an Administration Server. These are guidelines only:

• Quad core processors with 8 GB of RAM

• 300 MB of free disk space for the installation

Software Requirements

The following list describes the software requirements for Service Broker:

• Network Time Protocol (NTP) client

  Service Broker requires that all servers accurately synchronize their system clocks to a common time source, to within one or two milliseconds. Oracle recommends using an NTP client or daemon and synchronizing all Service Broker servers to a common NTP server.

  Caution:

  Synchronizing system clocks to within one or two milliseconds is critical for the system to function properly. If you do not synchronize server clocks, the system may display unexpected behavior.

• Service Broker relies upon a shared library of the underlying operating system to provide Stream Control Transmission Protocol (SCTP) support.

  If you are implementing a solution that uses Diameter over SCTP, you need to ensure that the operating system includes the following library:

  libsctp.so.1

  If needed, install the shared library on the operating system of each managed server host machine.

• Some Service Broker features require a database to store persistent information and two network applications require an Oracle database. See "Choosing a Database" for more information. Service Broker is compatible with these databases:

  • Oracle Database 11g release 2

  • Berkeley DB 4.1.21

• Oracle Universal Installer imposes additional system requirements and library dependencies. For example, it requires 500 MB of swap space to be available on the installation target system.

  For more information about Oracle Universal Installer, see Oracle Universal Installer and OPatch User's Guide.

Supported Operating Systems and JDKs

Service Broker can be installed on any of these 64-bit Unix/Linux operating systems:

• Oracle Solaris 11

• Oracle Linux 6

• Red Hat Enterprise Linux 6

Two compatible Java SE JDKs are bundled with the Service Broker installer:

• Oracle JDK 64-bit version 1.6.0_37, 1.7.0_9, or later

• Oracle JRockit JDK R28.2.5, or later

The Java JDK versions bundled with the product will vary according to the versions available near the time of product release.

Table 2-1 lists supported combinations of CPU type and JDK along with the name of the installer setup file.
