Dec: Marsh installed the current version of ImageMagick on
clamato for testing with the MDP access system. Snavely coordinated or
participated in a number of detailed discussions with the MDP group on
the rights database, conventions for naming handles, and mechanisms for
storing metadata on MDP processing and for MDP linking between Mirlyn
and the prototype access system.
Jan: Snavely, working with Wilkin, Willett, and Valentine,
developed and documented a strategy for rights information management
for MDP, and began discussions with DLPS staff on integration with the
access system. Feeman worked with DLPS staff to begin developing
scripts for creating METS files and handles for all MDP items, which
are dependencies of the access system being developed by DLPS staff.
Feb: Snavely completed discussions with DLPS staff on the design
and use of the rights database, and built the database. Feeman completed
initial work on scripts to generate METS files and handles, and created
them for all MDP volumes; continued work on download and validation scripting
(which will be made available to Google partners via networked CVS set up
by Snavely); developed overview documentation of the system; and began work on
scripting to populate the rights database.
Institutional Repository.
Shibboleth.
Dec: Snavely began discussions with ITCS to create a
lightweight project plan for a Shibboleth pilot project with ProQuest.
Jan: Snavely discussed the foundations of a project plan with
Doster to help ITCS with planning.
Infrastructure
Improvements to storage infrastructure, web server redundancy.
Dec: Marsh continued work on setting up the network storage
server on north campus, but ran into hardware problems with the storage
array and began troubleshooting.
Jan: Marsh solved the problem with the storage array on the
north campus storage server, completed the setup of networked storage,
and began installation and configuration of new web servers.
Feb: Marsh began compiling and installing a new web server
configuration on the new web servers which will include support for
mod_perl, PHP, SSL, and a tunable usage governer to slow or prevent
automated downloading.
COSIGN.
Jan: Snavely coordinated a discussion with DLPS staff on a
single service hostname for DLPS services, and DLPS decided on a name.
The new name will be used in the upcoming rollout of new web servers on
north campus.
Feb: Snavely met with Dueber and Lu to discuss the migration
process to COSIGN, and the impacts on Web Services applications; Snavely
also began planning a new cutover strategy involving a long transition
window in which Lib Auth credentials are obtained via COSIGN authentication.
Redundant MySQL.
Dec: Snavely set up TSM backups on soymilk, the MySQL
server on north campus and synchronized the installed packages on both
cowmilk and soymilk to ensure their configurations are identical.
Jan: Snavely set up replication on the new MySQL servers,
developed monitoring scripts to detect replication problems, and
created and timed a cutover plan. Sheppard, Snavely, and Weise tested
the new servers and coordinated a cutover involving only 35 minutes of
downtime.
Production server replacements/upgrades.
Dec: Marsh began meeting with storage vendors to seek
solutions and pricing for a major storage upgrade for the servers that
host Mirlyn and peripheral services.
Jan: Marsh continued to meet with vendors to discuss
additional details and gather pricing information.
Feb: Marsh, using scripting developed by Feeman, began to quantify
I/O performance characteristics on several of the servers that will use the
new storage to confirm requirements will be met.
Replace DLXS statistics.
Jan: Feeman began to review the COUNTER and SUSHI
guidelines for statistics systems for electronic research resources.
Develop an authentication and authorization management system.
Centralize LIT backup.
Formalize system administration infrastructure.
Dec: Marsh began to develop generic documentation for OS
installation and configuration that will be applicable to both Fedora
and Debian OS distributions.
Revisit logging practives.
DHCP/DNS services.
Development server replacements/upgrades.
Feb: Marsh upgraded clamato to Fedora Core 4.
Security assessment.
Work flow, processes, and organizational work
Trusted Digital Repository (TDR) compliance and quality management.
Documentation and standardization of processes.
Improve coordination of data loading.
LIT work requests and scheduling.
LIT on-call service.
Cost model.
Technology trends awareness.
Miscellaneous and/or unplanned activity
Dec: Jessica Feeman was hired as a programmer in Core Services,
and will start work in the new year.
Jan: Marsh upgraded the Oxygen XML editor to the newest version
on all servers.
Feb: Snavely, using an inventory of volumes supplied by Geitgey, began an analysis of all LLMC page images to determine the extent of problems in rendering derivatives, finding 122650 problem images on the first pass of analysis.
Snavely pursued getting console access to servers at the Duderstadt Center server environment, and Marsh worked with CAEN staff on the particulars of usage. CAEN staff will no longer provide non-business-hours support for hardware, so this capability was critical.
System Performance: All DLPS collections were degraded and may have been inaccessible for some users on Sunday, February 26 from 5:45am to 2:15pm due to a software version conflict.
