The following old versions of software will be removed from the CS Solaris systems during the Christmas semester break, the week of December 29.

Java

In general you should be using /p/java, but there are still a few applications that may require older versions for compatibility. The latest of major versions 1.4, 1.5 and 1.6 will be kept around for the time being.

/p/java-1.1.8_12 (/p/java-1.1)
/p/java-1.2.2_07 (/p/java-1.2)
/p/java-1.3.1_01 (/p/java-1.3)
/p/java-1.5.0_08: The latest 1.5.x version install is 1.5.0_16 (/p/java-1.5)
You probably should be using /p/java anyway
/p/java-1.6.0_05: The latest 1.6.x version install is 1.6.0_07 (/p/java-1.6)

The /u/u9 filesystem will be merged into the /u/u3 filesystem. During the more, the filesystems will be unavailable. Existing NFS filesystem mounts will need to be remounted. After the move, the machine Xinuserver.cs.purdue.edu will be removed from service.
5 January 2009: Locutus.cs.purdue.edu and the hosted wikis will be down from 8AM until about 9AM to reallocate disk space. The hosted wikis include

31 December 2008: Solaris 8 and Solaris 10 systems will be updated to the current patch level. They will be rebooted between 5:00 AM and 8:00 AM on Wednesday, December 31. Individual machines should only take about 5 minutes to reboot some time during the two hour window, but because of server dependencies the effective downtime may be longer.
30 December 2008: Sal.cs.purdue.edu will be down from 12PM until about 3PM to upgrade two of the disks.
29 December 2008: Maxd.cs.purdue.edu will be down from 8AM until about 11AM to upgrade two of the disks.
12 December 2008: ITaP will be rerouting the CS leased LWSN-to-HAAS connection to a new fiber run between 6AM and 6:30AM. The link should only be down for about 5 minutes. This will disrupt all CS network connections between HAAS and anywhere outside the HAAS building.
The new fiber was defective and the connection was eventually moved back to the old connection about 13:30.
