Hi eveyone,

I am new administering arsde. Our system is ArcSDE 9.3.1 with SQL Server 2005.  I started to work around 6 months ago and there is none in my team who knows about GIS. From the SDE_compress_log table I've found out the compress has not been ran for over 6 months. I was talking to our DBA and he mentioned about compressing the database in SQL. I am really confused about compressing the database. When our DBA mentioned he has compressed the database in SQL, is it the same as compressing the database through ArcCatalog?

Thanks,

Hi Thanks. Now I understand much better. I ran the script and sum all the records for the A and D tables.
A = 9969
D = 5299.

Is the above really bad? Or is it okay? I have heard the database could break if the compress is not ran. Could it happen

The feature class which has the largest number of A and Delete records is the ID =1511 with 6562 Adds and 2498 Deletes.

I suppose it depends on your definition of "break" -- the software is operating
according to design, and there's no reason to think it will stop working, but you
have edits that haven't made their way into the base tables.

Hi Thanks again.
I was told by an ESRI person if | did not compress the database it could break so I was concerned about the database will stop working. Some users are complaining about editing their feature classes being very slow. It is because I haven't move their edits to the base. Correct?

Thanks again.

Let me put it this way:  Failure to regularly compress a versioned geodatabase is not likely
to result in improved performance.  Causality is difficult to predict, but best practice isn't.
