HiEvery now and then I get a call from a site where Administration database has grown very large. It happens around every 2 month - but it is not consistent. Today I got the call again. The database is now 36 GB and growing and contains around 17.200 documents. It has lots of whitespace (only 0,9% space used).
Why does this happen? Do we have an ODS51 defect?
The server is the administration server and it is clustered with another server. Both are 8.5.1 FP1 ODS 51. On the other server the Admin4.nsf is only 112 MB.
They have 3.000 users on 4 mailservers in 2 clusters.
Subject: I´ve seen that …
…on other db´s not the admin4.nsf.Are the replicas similiar when it comes to number of docs?
Whats the retention interval?
Change retention interval to 10 days, max 21 days (technote avail.)
From a presentation:
Proper replication is required
Admin4.nsf should replicate as often as Directory
The size can grow unacceptably if it doesn’t
Replication retention should be standardized
The default is 7 days
10 is acceptable, as is 14 or 21
Anything longer is unnecessary and dangerous!
Improper replication causes old requests to “come back”
Causes server slowdowns
– Replication “storms” can occur
This is the number one cause of AdminP meltdowns!
Subject: Fixed for 1 server - now another has the issue
Thanks for your post.I checked and the retention (Removed documents not modified in XX days) was not consistent. I have set all servers to 10 days now.
After replicating around they are not in sync. Some Admin4 databases contain 3.000 documents ohter 4.000.
And 1 other server increased the Admin4.nsf to 36 GB. It was 600 MB when I fixed the first admin database earlier today but as of now 36 GB and server is out of disk space…but the amount of documents in Admin4 on this server are the same as earlier this afternoon, so 99% is whitespace.
I will take the server off line now and compact the Admin4.
I have not seen this in R7. Is this a R 8.5 bug? ODS51 bug or…?
Subject: Note…
And a note:When accessing database properties for the database growing very large and clicking on “%used” on the “i” tab crashes the Domino Administrator (and Notes client).
Subject: Would not advise setting remove documents not modified that low
You should not set that value lower than the maximum number of days that an admin request can remain pending.
For example, a user rename request will remain pending for up to 21 days by default.
Better to use 30 days for the “documents not modified” setting so that you don’t artificially truncate these other processes.
