When you exec the ConfQueryConfStatistics in the lyncserver\rtclocal.rtc database it returns 5 rows labelled 0,1,2,3,4.
I can see that:
Row 0 is the total number of unexpired conferences
Row 1 is the total number of active conferences
However, what do the figures in rows 2, 3 and 4 represent (rows 2 and 3 always appear to return the same number)?
We have had an issue with a UCMA 4 application since we installed Lync2012 CU3 in that Lync doesn't appear to be expiring conferences created by the app anymore.
The SDK says that the conference expiry time, if not explicitly set on the conference object, will default to creation time +8 hours. I suspect that since CU3 was applied, the default is not being set anymore (the expiry time field in the Conference table in the rtc db contains null for the conferences created by the app). Consequently none of our conferences created using UCMA have an expiry time and are not expiring. This is can be seen as the first number returned by the stored proc never goes down ~ only up.
This stored proc has been valuable in analysing the situation but would be good to know what rows 2, 3 & 4 represented.
