Section 2: Request

2.1 Please describe the proposed Specification:

ECperf 1.1 is a maintenance release of ECperf 1.0. The goal is to fix any bugs or discrepencies found as we gain more experience with ECperf 1.0. We may undertake minor enhancements if deemed necessary to make this a better workload.

2.2 What is the target Java platform? (i.e., desktop, server, personal, embedded, card, etc.)


2.3 What need of the Java community will be addressed by the proposed specification?

A stable, robust, standard EJB performance workload

2.4 Why isn't this need met by existing specifications?

There are no standard workloads today

2.5 Please give a short description of the underlying technology or technologies:

Various APIS in J2EE 1.2, primarily EJB 1.1

2.6 Is there a proposed package name for the API Specification? (i.e., javapi.something, org.something, etc.)


2.7 Does the proposed specification have any dependencies on specific operating systems, CPUs, or I/O devices that you know of?


2.8 Are there any security issues that cannot be addressed by the current security model?


2.9 Are there any internationalization or localization issues?


2.10 Are there any existing specifications that might be rendered obsolete, deprecated, or in need of revision as a result of this work?


2.11 Please describe the anticipated schedule for the development of this specification.

Since this is a maintenance release, we hope to turn it around in 7 months, targetting a final release by Feb 2002.

2.12 Please describe the anticipated working model for the Expert Group working on developing this specification.

The Expert Group will work in the same way the ECperf 1.0 Expert Group has. This has worked successfully for us. We have weekly conference calls with proposals sent in via email in advance. Discussions are informal and most decisions are made via consensus.

Section 3: Contributions

3.1 Please list any existing documents, specifications, or implementations that describe the technology. Please include links to the documents if they are publicly available.

See for the ECperf 1.0 specification.

3.2 Explanation of how these items might be used as a starting point for the work.

Section 4: Additional Information (Optional)

4.1 This section contains any additional information that the submitting Member wishes to include in the JSR.
