WebSphere Event Broker has the following requirements
on distributed systems:
- 512 MB of RAM are required to support runtime operations (1 MB equals
approximately 1000 000 bytes).
- 512 MB of RAM are required to support Message Brokers Toolkit operations
on Linux (x86 platform) or Windows.
This is the minimum supported level; for improved performance, provide 1 GB
(1 GB equals approximately 1 000 000 000 bytes).
- Disk space requirements are dependent on the components that you install
and the working space that is required by those components (for example, for WebSphere MQ queues and persistent messages).
The
installation wizard displays the actual requirements for each component that
you have selected for installation, excluding temporary space. The table below
provides figures for guidance that might vary with different operating systems.
If you install just one or two of the runtime components, the storage required
is reduced by only a small amount.
Component |
Space required on Windows |
Space required on Linux (x86 platform) |
Broker, Configuration Manager, and User Name Server |
315 MB plus 300 MB temporary space |
280 MB plus 300 MB temporary space |
Event Broker Toolkit |
4.2 GB plus 1.5 GB temporary space |
4,2 GB plus 1.5 temporary space |
- If you install one of the database products supplied with WebSphere Event Broker,
you need additional disk space:
- DB2 Enterprise Server requires approximately 300 MB. This is for a Compact
installation which provides sufficient function for WebSphere Event Broker;
if you choose a Typical or Custom installation additional storage might be
required.
- On Windows, ODBC (Open Database
Connectivity) drivers for Cloudscape require approximately 105 MB.
- On systems on which you create a broker, approximately 10 MB is required
for the broker tables. If you create user databases that are accessed
by message flows, additional space is required on those systems.
- Temporary disk space is required during installation as shown in the table
above. This space is required in the location pointed to by the TEMP system
variable, not the folder into which you install the product. The temporary
files are deleted when installation has completed.
For all storage requirements on z/OS, see the section about "DASD
Storage Requirements" in the Program Directory for WebSphere Event Broker for
z/OS or the Program Directory for WebSphere Rules and Formatter
Option for z/OS.
