Sun Java System Portal Server 7.2 Installation and Configuration Guide

Checking Hardware and Software Requirements Before Installing Portal Server 7.2

This section contains the requirements for installing Sun Java System Portal Server 7.2.

Note –

The installation instructions are specific to the Solaris and Linux platforms.

This section includes the following sections:

Hardware and Operating System Requirements

The following table lists hardware and operating system requirements:

Table 1–1 Hardware and Operating System Requirements

Component 

Platform Requirement 

Supported platforms 

Sun BladeTM or comparable workstation or server

Operating system 

SolarisTM 9 or Solaris 10 on SPARC®

Solaris 9 or Solaris 10 on x86 

Red Hat Enterprise Linux 4.0 on x86 

RAM 

2.0 Gbytes for regular deployment on Sun Java System Application Server. 

Disk space 

1 Gbyte for Portal Server and associated applications. 

Swap space 

Twice the amount of physical memory. For example, if your machine has 2.0 Gbytes RAM, the swap space should be 4.0 Gbytes swap space. 

For Application Server 9.1, memory and disk space should be a minimum of 256 MB and 250 MB respectively. 

Browser Requirements

Portal Server 7.2 web-based user interfaces are supported on all web browsers that support the following standards on recent major versions:

The following features in Portal Server 7.2 are dependent on specific browser capabilities.

The following web browser / OS combinations are known to support the above standards and the special capabilities that are required for all Portal Server 7.2 features:

Before Installing on Linux

Software Requirements

Before you begin installing Portal Server 7.2, you need to have the following requirements:

Miscellaneous Checks

  1. If the system on which you installed Portal Server does not have direct connectivity to the internet, an HTTP proxy needs to be specified. For example, for Application Server 9.1, specify the following in the domain.xml file:

    <jvm-options>-Dhttp.proxyHost=proxy-host</jvm-options>
<jvm-options>-Dhttp.proxyPort=proxy-port</jvm-options>
<jvm-options>-Dhttp.nonProxyHosts="portalserver-host"</jvm-options>

    Where, proxy-host is the fully qualified domain name of the proxy host, proxy-port is the port on which the proxy is run, and portalserver-host is the fully qualified domain name of the Portal Server software host.

  2. Execute the command prtconf | grep Memory to check RAM.

  3. For Linux, you can check the memory and swap size form the meminfo file. Use the vi /proc/meminfo command to view the meminfo file.

  4. Use the command swap -l to see how much swap space your machine has. To temporarily increase your swap space by 4 Gbytes, you can use the following instructions:

     mkfile 4g /swap-filename
 swap -a /swap-filename

    where swap-filename is an empty file to be used as a swap area.

  5. To increase the swap size on Linux, use the following instructions:

    1. Create a swap file by using the mkswap /directory-name/swap-filename command.

      Note –

      You can create the swap file on any directory, where the disk space is available.

    2. Mention the swap file name where you need to increase the swap size by using the swapon /directory-name/swap-filename command.

    3. Increase the swap size by using the /directory-name/dd if=/dev/zero of=/directory-name/swap-filename bs=1024 count=x command.

      where x is a variable that depends on the amount of swap you need to increase. The variable can be in the multiples of blocksize (bs), which is 1024.

    4. Remove the swap file by using the rm —rf /directory-name/swap-filename, since the swap file consumes huge disk space.

    5. The amconfig script and other configure later utilities, require the JDK to be installed and linked to /usr/jdk/entsys-j2se. This looks like the following:

      lrwxrwxrwx 1 root root 27 Jan 17 09:28 entsys-j2se -> /usr/jdk/instances/jdk1.5.0
