JoiMint-eLog

• Matthias Clausen

2
eLog and applications

• Integration of eLog into applications (JoiMint)
• Integration of JoiMint-MIME type and JoiMint
  config files into eLog

3
Requirements for our eLog approach IExtended
Functionality

• Start from the existing eLog at DESY
  (TTF-Version)
• Keeping the following ideas
• Write messages, screen dumps and files through
  central print queues (survive database downtimes)
• Use Web interface to add and to edit entries
• Use Servlets to retrieve data from the eLog and
  to prepare Web displays.
• Keep the XSLT style sheet to generate the Web
  edit page

4
Requirements for our eLog approach IINew
Functionality

• Access and display of multiple eLog sources.
• Storing messages, screen dumps (JPG) and any kind
  of files into an Oracle database. (Rather than
  XML files)
• Support links between messages
• Support for entries and screen dumps on Unix and
  Windows
• (Windows bypassing default PostScript printer
  driver)
• Support command line entries.
• Write from applications

IntegratingeLog lt-gt JoiMint

• Create entries in JoiMint and save them into the
  eLog (Oracle)
• Save JoiMint config files and/or configdata
  files into eLog
• Create html links with the MIME type ltJOIgt and
  start JoiMint from eLog entries

Experience

• Tomcat is just stable (no crashes ever)
• Oracle performance extremely good
• Oracle server in computing center
• Performance _at_ DESY
• 50 images _at_ 100k
• ... Which implies 51 interactions with Oracle
  server
• ... in 2 sec
• 100 messages (text) from 5 log books (5
  interactions)
• ... in 1-2 sec
• (limits 50 images / 100 messages configured in
  config class)

Plans - I

• Add alarms
• Use existing alh-gt Oracle functionality and write
  alarms directly into Oracle
• Query alarms in eLog
• Create http links for
• JoiMint -gt archive data
• JoiMint -gt alarm settings
• ...

17
Plans - II

• Add support for cmlog (as source)
• Line oriented view ( like JLAB eLog)
• Configure eLogs in (XML) config file
• Add eLog-sources by Java plugins
