Power interruption at SDSC to facilitate upgrade of Emergency Power Off switch

Downtime for CRBS equipment varies from no interruption to down for the duration.  We are working to acquire additional hardware that will either shorten or eliminate the outage for most servers.  Some servers, particularly the CRBS cluster and the CCDB cluster, including non-cluster machines located in those racks, will be unavailable for the duration of the power interruption.  A list of affected servers, and the extent to which they will be impacted can be found here .

Upgrade of server and software for Jira, Confluence, Crowd and Fisheye/Crucible

 

Tues., Aug. 18, 2009
9pm - midnight

Upgrade of bamboo.crbs.ucsd.edu build test server from version 2.2.3 to version 2.3

Go here for more details of the new version.

COMPLETED
Sun.,, Aug. 16,  6pm -
Mon., Aug. 17, 7am

Production Oracle RAC database server is being patched and moved from the nbirn.net domain to the crbs.ucsd.edu domain.  During this outage, status information can be found at http://support.crbs.ucsd.edu and/or http://status.crbs.ucsd.edu

As of 7:14 am, the Oracle RAC upgrade and domain name change are complete. 
At this time, all Oracle RAC databases are back online and functioning nominally.

As of 3:35am, upgrade was progressing, but not yet complete.  Next update will be at 7am, Monday, August 17th.

For applications:
   * if you use an IP,  you must change it to a FQDN (Fully Qualified
     Domain Name) that has "crbs.ucsd.edu" in it.    
   * If you use an FQDN that has "nbirn.net" in it, you must change it
     to the appropriate/analogous "crbs.ucsd.edu" FQDN.
Examples of where modifications might be needed include properties files that configure jdbc connections and tnsnames.ora files that configure oracle clients.
You can go ahead and make any necessary changes to applications at your convenience, prior to the work Sunday night, as the new entries are already in DNS.

Sunday, July 19, 2009 1:30pm - 8:00pm

Changes to network infrastructure at SDSC.  These changes affected every server/service hosted at SDSC.  Most experienced only a simple, if extended, loss of network connectivity.  However, the Oracle RAC had to be restarted.

Completed except for restart of Oracle RAC and verification of any systems that use it.
