PV Client Crawlers
• Janet Anderson at APS has built the following PV client
•
•
crawlers:
- MEDM clients (.adl files)
- Alarm Handler (.alh)
The Alarm Handler and MEDM crawlers have been tested at
APS
These crawlers are installed in the tarball
- Useful as ‘prototype’ crawler code example

PV Crawler Enhancements
• Crawler inserts directly into the RDB
•
- ‘Agnostic’ (Oracle sequences vs MySQL Autoincrement)
- 2 sets of DDL - template for different vendor RDBMS
PV Crawler - minor tweaks
- PV schema has remained unchanged
- 100% ‘reach’ at APS

Congratulations to this first roll-out.I immediately downloaded this first version and
got it running here at BESSY.
The result is: I successfully crawled all of our machine-group IOCs, adl-files and
alh-files.
And the PV-viewer works just fine.
There were just little changes I had to make to get everything working (see attached
diff-output).

I just started writing the crawlers that I volunteered for (burt, cdev,

Are there plans to set up a forum/wiki/mailing-list for irmis-related
questions/documentation/...?
Greetings from Berlin,you really did a good job.

Enhancements (cont’d)
• SNS PV crawler enhancements
•
•
•
- save intermediate ‘path’ results of parsing cdCommands
- should these be in IRMIS::Base – or are they site specific?
- possibility: store this information as part of the ioc attr table?
XAL enhancements
- Desktop

• If the miner is run at boot time:
-
alert user if new records detected without corresponding entries
in the component database.
- increase the ‘exhaustive’ coverage of the hardware database
as well as the PV-to-HW connections/links
