2. Obtaining and Installing Software

To download this release, go to the 5.0.3 Download page.

For information on installing this release, go to the 5.0.3 Installation Guide.

2.1. Java Client API Download

GT 5.0 does not include any of the CoG JGlobus Java APIs that were included in the GT4 release series.   But, the JGlobus APIs can still be used with the GT5 services.  You can get them directly from the CoG JGlobus releases; see the following link:

http://dev.globus.org/wiki/CoG_jglobus

Consider the following when determining which version of CoG JGlobus to use:

  • The GRAM development team used CoG JGlobus version 1.6.0 for performance testing.

  • The BIRN project used CoG JGlobus version 1.6.0 (plus patches) for GridFTP testing. All patches are included in 1.8.0.

  • At the time of the GT 5.0.3 release, 1.8.0 was the recommended version.  In general, the latest recommended CoG JGlobus version should be used.

8. Summary of Changes Since 5.0.2 (by component)

8.1. Summary of Changes in GridFTP

  • Normally in stream mode the destination is the pasv side for a third party transfer, and the server is the pasv side for two party (client->server) transfers. Two party transfers also had a failover mode where if the PASV command failed, it would automatically switch to PASV on the client end. This allows a server that knows it must connect out to disable the PASV command and all clients will work the way it wants. However, this auto-failover feature was not implemented for third party transfers. The auto-failover for third party transfers is available in this release.

8.2. Summary of Changes in RLS

  • None since GT 5.0.2.

8.3. Summary of Changes in GRAM5

  • Improved diagnostics for RSL validation file parsing errors. If an RVF file contains an invalid attribute or syntax error, the job manager will include the parse error as an extended error message containing the path to the file and the invalid part of the file.
  • Improved diagnostics for missing -condor-arch and -condor-os configuration errors. If a job manager is misconfigured for condor, it will send an error message indicating what configuration option is missing.
  • Remove confusing log messages about state file ownership when a job manager starts up on a multi-user system.

8.4. Summary of Changes in GSI

No major changes since GT 5.0.2.

8.5. Summary of Changes in MyProxy

GT 5.0.3 contains MyProxy 5.3. See the MyProxy Release Notes for more details on this and other MyProxy versions.

8.6. Summary of Changes in GSI-OpenSSH
