This topic describes the disk space required to install WebSphere
Process Server and related products, on all supported platforms. The directories
given are the default installation directories for the various products.

To review WebSphere Process Server detailed system requirements,
go to
http://www.ibm.com/support/docview.wss?uid=swg27006205 and
select the link to your version of WebSphere Process Server. If there is a
conflict between the information provided in this topic and the information
on the detailed system requirements Web pages, the information on the Web
pages takes precedence. The information in this topic is provided as a convenience

Required disk space on AIX platforms
Manually verify
that the required space for creating a profile is available. A known problem
in the underlying InstallShield for Multiplatforms (ISMP) code prevents proper
space checking on AIX systems.
WebSphere Process Server requires the
following disk space:
1795 MB for the install_root directory,
including 1480 MB for the installation of WebSphere Application Server Network
Deployment before creating profiles
The installation root directory includes the core product files, Sample
applications gallery, and Public API Javadoc(TM). This size does
not include space for the deprecated features, profiles, or applications.
Profiles require 60 MB of temp space in addition to the sizes shown.
Profiles have the following space requirements:
- 73 MB for a deployment manager profile
This size does not include space for applications that you might deploy
or nodes that you might federate to this deployment manager.
- 248 MB for a stand-alone process server profile with the Sample applications
and the sample Business Process Choreographer container
This size does not include space for applications that you might develop
and install.
- 53 MB for an unfederated custom profile
This size does not include space for applications that you might develop
and install. The requirement does include space for the nodeagent. However,
you must federate a custom profile to create an operational managed node.
After
federating a custom profile, the resulting managed node contains a functional
nodeagent only. Use the deployment manager to create server processes on the
managed node.
- 60 MB temporary space for profile creation
- This space must be provided in addition to the profile sizes listed above.
An error can occur during profile creation if you do not provide enough system
temporary space.
- 600 MB for the /tmp directory
The temporary directory is the working directory for the installation
program. The actual space required for the
/tmp directory can vary,
as follows:
- If you elect to silently install a new instance of WebSphere Application
Server Network Deployment during installation of WebSphere Process Server,
a total of 600 MB of temporary space is required.
- If you install WebSphere Process Server over an existing installation
of WebSphere Application Server or WebSphere Application Server Network Deployment,
and the existing installation requires fixes or features added to it, a total
of 600 MB of temporary space is required.
- If you install WebSphere Process Server over an existing installation
of WebSphere Application Server or WebSphere Application Server Network Deployment,
and the existing installation is at the supported maintenance level, little
or no temporary space is required.
2395 MB total requirement 
This amount is the total space requirement when installing the product
from the CD and when not installing service (Fix Packs, service packs, refresh
packs, etc.). Installing profiles requires more space.
The following space is required for the IBM HTTP Server
product:
- 110 MB for the /usr/IBMIHS directory
The IBM HTTP Server product requires this space.
- 35 MB for the /usr/ibm/gsk7 directory

for the Web server plug-ins for WebSphere Application Server or WebSphere
Application Server Network Deployment:
- 200 MB for the /usr/IBM/WebSphere/plugins directory

- 25 MB for the /usr/ibm/gsk7 directory
The Tivoli Global Security Kit requires this space.
The following space is required for the WebSphere Application
Server Clients:
- 150 MB for the /usr/IBM/WebSphere/AppClient directory
The amount of space required to install the application clients is
actually less than 150 MB. The amount of space depends on the clients that
you install as features.
The Installation Wizard for each component displays
required space on the confirmation panel before you install the product files
and selected features. The Installation Wizard also warns you if you do not
have enough space to install the product.
