In this example, Rational® Asset Manager supports
200 concurrent users and 10,000 assets.
Every
asset contains one artifact; the artifacts vary
in size:
- The largest artifact is 375 MB
- The smallest
artifact is 4 KB
- 80% of the artifacts are smaller than 10
KB
- 12% of the artifacts are 10 - 100 KB in size
- 5%
of the artifacts are 100 KB - 1 MB in size
- 3% of the artifacts
are 1 - 375 MB in size
Your users are doing these
activities:
- 90% of the time, they are searching with keywords
to find, view,
and then download assets.
- 5% of the time, they are submitting
assets.
- 5% of the time, they are viewing their My Dashboard
page, community
pages, or forums.
For this configuration of assets
and user activity, you
need this minimum equipment:
- A high-speed internal network
- A server dedicated to running the limited embedded WebSphere® Application Server and the included IBM® DB2®.
The server must meet these specifications:
- Processor: a dual-processor
64 bit CPU
- Memory: at least 4 GB of RAM
- Usage: dedicated
to running the embedded WebSphere Application
Server and IBM DB2
- Performance settings: WebSphere Application
Server is configured to use a JVM heap size of 2 GB, which is the
recommended maximum
- Storage: on your hard disk drive, you
need at least 50 GB for
the persist (artifact) storage, 2 GB for storing the search index,
5 GB for the asset database, and 5 GB for the lifecycle database
In general, to support more concurrent users
you must
add more nodes and servers (which requires WebSphere Application Server Network Deployment
edition), increase the memory, or use faster hard disks.
