Y2K Testing Continues in the Autumn

Sverre Jarp , (CERN Y2K co-ordinator) IT/DI

Testing under UNIX


A special AFS cell '' has been established to allow service managers and users to test Y2K compliance.

In addition to AFS, the cluster consists of machines representing all the Unix flavours in use at CERN (AIX, DUNIX, HP-UX, IRIX, LINUX, and SOLARIS).

More information can be obtained from the page:

Testing schedule

The cluster will be set to 25 December 1999 on fixed days and then left running for two weeks. This gives people one week to prepare test programs in 1999 and one week to check the consequences of passing into year 2000. At the beginning of the third week the date will be set to 25 February 2000, which offers one week to test the leap year issue (29 February 2000 exists because the year is divisible by 400).

The dates are set as follows:

Note that the date changes always occur on Wednesdays !


The following Web page should be used for account registration:

By registering your name and mail address on this page, you will be given a user-id on the first day of each test period. The user-id will be valid for the corresponding period and will then be taken away for new usage. If you do not complete your tests in one cycle and wish to retain your account and the files in it, you must reissue the request via the registration Web page.


The machines all run Y2K-compliant versions of the operating system. There is a reasonable amount of disk space in the y2k cell for home directories. Users can only access what is world-accessible in their real afs directories in the CERN cell. File copying is therefore recommended (also to avoid that the Y2K-testing alters real production files or products).

Note that LSF is not available. Tape access must be requested explicitly (via the registration Web page).

The latest news, related to the test environment, will be posted on the Web pages mentioned above.


NICE Y2K testing (for PCs)

The NICE Y2K test environment is now up and running. You can find all the necessary details on the NICE Y2K Web page at:
