CAT Chat Minutes

April 7, 2000

Information and Follow-up Items

1. When are the new name servers expected to be operational?

They are expected to be operational by end of April.

2. APS Users are notified by e-mail of their elapsed training. Can the Cat Directors also receive a copy of the e-mail?

For APS employees their supervisors are automatically notified by e-mail. We are in the process of setting this up for the APS Users. The CAT safety representative will be notified by e-mail. If the CAT would like someone other than the safety representative to be notified, inform your floor coordinator so they may set-up accordingly.

3. Severe weather will be here shortly, which might cause power interruption. What actions are being taken to keep the network router operational without interruption?

At the current time the routers in the LOM network closets do not have any UPS. We have in the planning to install them later this year.

User Operations

Rod presented three viewgraphs to the group. The 1st graph displayed Run Statistics by Week for run 2000-1. During the 11 weeks long run, the mean time between faults was 42 hours for an overall 96.74% availability. The 2nd graph displayed the Run Statistics from FY1998 through present. The 3rd viewgraph displayed Downtime by Systems for FY1999 to present. This gave a percentage of downtime caused by various systems.

At this time, the PV gateways are being upgraded to improve performance. In addition separate PV gateways will be installed for the first 8 sectors. Also using the IOC as a gateway will also be tested on 2 more sectors.

General Information

Notification of training for ANL Users was an area of discussion. A message was sent to 450 users of courses that have expired or will be expiring soon. This message should have gone out to only 117 resident ANL users. The floor coordinators will meet with J. Lang to verify those 117 users. The message will again be sent out in May to those 117 names that are listed. If for some reason, a non-ANL user receives a message, please let your floor coordinator know as soon as possible so we can update our records.

The server oxygen will be shutdown this evening, Friday, April 7, for replacement of a failing CPU module. This was diagnosed by Sun Technical Support as the cause of the oxygen crash on Wednesday evening. The shutdown will start at approximately 5:00 p.m. The repairs should be completed by 6:30 p.m.
