EMI 2 (Matterhorn) - Update 21 (21.12.2013) - v. 2.10.5-1

The Update contains:

  • revision release of dCache server, v. 2.2.21 and dCache srmclient, v. 2.2.22

dCache server, v. 2.2.21 and dCache srmclient, v. 2.2.22

Affected services

  • affected service: dCache server, UI ,WN

What's new:

  • dCache server, v. 2.2.21
    • The upgrade from jGlobus 1.8 to 2.0 introduced a performance regression: the last-modified time of CA-related files are checked for each request, which, when these files are stored on a shared filesystem, introduces unacceptable latency. This release uses an updated jGlobus that throttles how often it checks the last-modified attribute of files.
    • The rebalancer command accepts options to modify its behaviour. The online help has been updated to better describe these options.
    • For more details see sCache server 2.2.21 - Extended Release Notes
  • dCache srmclient, v. 2.2.22
    • The SRM Client 2.2.22 follows the FHS compliant directory layout.
    • Changes:
      • Migration to jglobus2.0: SRM client now supports secure hash algorithm SHA-2 and therefore SHA-2 signed certificates. jGlobus2.0 also supports SHA-1 signed certificates. Please be aware that VOs are encouraged not to issue SHA-1 certificates any longer. Migrating to this version of SRM Client is therefore recommended.
      • Switch to jglobus with jumbo proxies support. There was a problem with growing proxies which would at some point cause problems with SRM. This fix solves the jumbo proxy issue.
    • For more details see dCache srmclient 2.2.22 - Extended Release Notes
