Oracle schemas and accounts
The IRMIS database schema is installed in 4 SLAC Oracle instances:

MCCQA IRMISDB schema: Production for all gui’s and applications. Contains data populated nightly by perl crawler scripts from production IOC configuration files. Data validation is done following each load.
MCCO IRMISDB schema: contains production data, currently for 3 tables only: bsa_root_names, devices_and_attributes, curr_pvs. MCCQA data is copied to MCCO once it has been validated. So MCCO is as close as possible to pristine data at all times.
SLACDEV contains the 3 schemas which are used for developing, testing and staging new features before release to production on MCCQA (see accounts below)
1. _SLACPROD_ IRMISDB schema: this is obsolete, but will be kept around for awhile (6 months?) as a starting point in case the DB migration goes awry somehow.

Other Oracle accounts

· IRMIS_RO – read-only account (not used much yet – but available)

...

IOC_MGMT – created for earlier IOC info project with a member of the EPICS group which is not active at the moment- new ioc info work is being done using IRMISDB

For passwords see Judy Rock or Poonam Pandey or Elie Grunhaus.

As of September 15, all crawler-related shell scripts and perl scripts use the getPwd script (Greg White) to get the latest Oracle password. Oracle passwords must be changed every 6 months; new passwords will be given to Ken Brobeck to update the secure master password files at password change time.

** The IRMIS GUI and the JSP application still use hardcoded passwords. These must be changed “manually” at every password change cycle.

Database structure: see schema diagram below. (this diagram excludes the EPICS camdmp structure, which is documented separately here: <url will be supplied>)

Crawler scripts
The PV crawler is run once for each IOC boot directory structure. The LCLS PV crawler (runLCLSPVCrawlerLx.bash) runs the crawler only once. It is separate to enable it to be run on a different schedule and different host which can see the LCLS IOC directories. Also, the crawler code has been modified to be LCLS-specific; it is a different version than the SLAC PV crawler.

The SLAC PV crawler (runSLACPVCrawler.csh) runs the crawler a couple of times to accommodate the various CD IOC directory structures.

cron jobs·

LCLS side: laci on lcls-daemon2: runLCLSPVcrawlerLx.bash: crawls LCLS PVs and creates lcls-specific tables (bsa_root_names, devices_and_attributes), copies LCLS client config files to dir where CD client crawlers can see them.

...

LCLS side: laci on lcls-daemon2: caget4curr_ioc_device.bash: does cagets to populate curr_ioc_devices for the IOC Info APEX app. Run separately from the crawlers because cagets can hang unexpectedly – they are best done in an isolated script!

...

CD side: cddev on slcs2: runAllCDCrawlers.csh: runs CD PV crawler and all client crawlers, data validation, and sync to MCCO.

...

FACET side: flaci on facet-daemon2: runFACETPVcrawlerLx.bash: crawls FACET PVs, copies FACET client config files to dir where CD client crawlers can see them.

PV crawler operation summary
For the location of the crawler scripts, see Source code directories below.
Basic steps as called by cron scripts are:1.

run FACET pv crawler to populate MCCQA tables

...

run LCLS pv crawlers to populate MCCQA tables

...

run CD pv and pv client crawlers to populate MCCQA tables

...

run Data Validation for PV data in MCCQA

...

if Data Validation returns SUCCESS, run synchonization of MCCQA data to selected (3 only at the moment) MCCO tables.

...

run caget4curr_ioc_device to populate caget columns of curr_ioc_device

** For PV Crawlers: the crawler group for any given IOC is determined by its row in the IOC table. The system column refers to the boot group for the IOC, as shown below.

* The PV client crawlers load all client directories in their config files; currently includes both CD and LCLS.

LOGFILES, Oracle audit table

Log filenames are created by appending a timestamp to the root name shown in the tables below.

The major steps in the crawler jobs write entries into the Oracle CONTROLS_GLOBAL.DATA_VALIDATION_AUDIT table. Each entry has these attributes:o
