Applying Server Updates (Oct 30)

This Sunday, October 30th between 6AM and 10AM we will patch and reboot operating systems. Most security updates can be applied without rebooting, but the changes we are making require a server restart. We are also going to take this opportunity to patch the Oracle Database software as well.

Most server outages will be brief since a restart takes less than a minute. However, the larger Voyager and Oracle servers could be down for around a half-hour.

UIUC Firewall Maintenance

The UIUC Campus Firewalls will be upgraded which could cause network outages for anyone off-campus connecting to CARLI services.

Network staff have indicated that the outages should be brief during this window.

VuFind and SFX Maintenance this Sunday, Oct 2nd

This Sunday, October 2nd between 6AM and 10AM, the VuFind (https://vufind.carli.illinois.edu) and SFX (http://sfx.carli.illinois.edu) services will go offline briefly while servers are moved behind a network security device.

To report a problem with those services after 10:00 AM on Sunday, please call 866-904-5843, press 0, and leave a message. Emails sent to support at carli.illinois.edu may not be answered until normal business hours.

Voyager and VuFind Problems this Afternoon (Sept 14th)

I apologize for the Voyager and VuFind outage this afternoon. I was doing prep work for this Sunday morning and made one change too many. The servers did not go offline but they were unable to talk across the network to the Oracle databases.

The prep work has been removed and no further changes will be made until the servers are powered down this Sunday morning.

Scheduled I-Share/Voyager Downtime on Sunday, September 18, from 6-10am

On Sunday, September 18, all I-Share/Voyager-related CARLI-supported systems will go offline for maintenance between 6:00 AM and 10:00 AM.
 
I-Share/Voyager services include: VuFind local catalogs, the I-Share union catalog, WebVoyage local catalogs, Z39.50, Voyager staff clients, and Voyager MS Access Reporting.  (Voyager Offline Backup Circ [https://www.carli.illinois.edu/products-services/i-share/circ/usingobc] may be used during the downtime, if needed.)
 

SFX Outage (June 24, 2016)

Last night (June 23) at 10:30PM I staged a firewall rule in a new security device for the Production sfx.carli.illinois.edu server. This rule was disabled but it appears that the existance of the rule blocked network access to the server. The rule was removed at 7:00AM this morning restoring service.

Throughout the rest of June and July, I will be migrating more services behind the security device and there will most likely be more interruptions to service. I will try to make sure they are short disruptions and I apologize for the outage.

Scheduled Downtime Saturday May 21st, 4AM-Noon

All CARLI services will experience interruptions in service while the University of Illinois network staff performs significant maintenance on the network exit infrastructure.

I-Share/Voyager services affected include: VuFind local catalogs, the I-Share union catalog, WebVoyage local catalogs, Z39.50, Voyager staff clients, and Voyager MS Access Reporting.  (Voyager Offline Backup Circulation may be used during the downtime, if needed.)

Emergency Patching at 11PM Tonight (Feb 17, 2016)

There is a new glibc vulnerability (CVE-2015-7547) that affects most Linux systems. It may allow remote code execution on the servers, so I will patch and reboot all CARLI servers starting at 11PM tonight (Wednesday, Feb 17).

For most servers this will be a quick reboot. For Voyager, it will probably be down for about 20 minutes while the Oracle database server is rebooted.

Voyager Outage (Dec 4th, 2015)

We have a batch job that has been failing this week and we have a ticket open with Ex Libris. We did not realize that the failed jobs were generating 4GB core dumps. At 2:10AM this morning the core dumps pushed the disk volume to 100% capacity. At approximately 8:50AM we identified and removed the core dump files to restore service.

This failure did not generate any automated alerts, so we will need to revise our monitoring.

All CARLI Services scheduled downtime: Friday, October 23, 2015, 3am-5am

UIUC networking staff will perform maintenance this week affecting CARLI services. Please notify your library staff working Friday morning.
