Fixing the deviceSearch and componentSearch catalogs

It seems that the deviceSearch and componentSearch catalogs can become corrupt. The reason(s) for this aren't understood at this point, but you can fix them.

Removing Stale References from the catalogs

Follow these steps to remove stale references from your catalogs.

1. Go to the shell and switch to the zenoss user "su - zenoss"
2. Run "zendmd" to enter the interactive shell
3. Paste the following script into zendmd.

problems = True
while problems:
    problems = False
    brains = dmd.Devices.deviceSearch()
    for d in brains:
        try:
            bah = d.getObject()
        except Exception:
            print "Removing non-existent device from deviceSearch: " + d.getPath()
            dmd.Devices.deviceSearch.uncatalog_object(d.getPath())
            problems = True

problems = True
while problems:
    problems = False
    brains = dmd.Devices.componentSearch()
    for d in brains:
        try:
            bah = d.getObject()
        except Exception:
            print "Removing non-existent component from componentSearch: " + d.getPath()
            dmd.Devices.componentSearch.uncatalog_object(d.getPath())
            problems = True
