 Hi,

 

I was trying to figure out why my db keeps growing exponentially and was looking through the scheduler. I decided to Enable a few of the scheduled events to see if this would help: PurgeUsersOnline, PurgeSiteLog, PurgeLogBuffer, and PurgeCache.

When I did this it has now left the install DEAD! All I get is: [HttpException (0x80004005): Request timed out.]
DNN: 4.9.3
 
Do you know if there is a way to undo these changes manually - in a config file or something on the server? I tried swapping my web.config for an older version but this had no affect.
 
I am pretty sure this is something that would require sql - if someone can point me in the right direction I would appreciate it.

I appreciate your help.
Cheers,
Pat

You can disable the jobs by executing the following SQL from Management studio:

UPDATE SCHEDULE SET enabled = 0 WHERE TypeFullName Like '%Purge%'

subsequently, you should examine which of the tabled exaggerate size, e.g by running (separately) the following commands in Host :: SQL text box:

SELECT Count(*) FROM {databaseOwner}{objectQualifier}SiteLog

SELECT Count(*) FROM {databaseOwner}{objectQualifier}EventLog

SELECT Count(*) FROM {databaseOwner}{objectQualifier}ScheduleHistory

SELECT Count(*) FROM {databaseOwner}{objectQualifier}SearchItemWords

Also make sure, the database gets backed up frequently with truncating the transaction log, if using full recovery scheme.

Hey Sebastian,

You are the man!! That worked perfect!

I got the scheduled sql jobs module from IowaComputerGurus.com which has significantly slowed the growth of the database but I still have to run a sql to truncate the log files manually at least once a week. Is this normal?

I haven't done the sql's you mentioned above yet but I am assuming that these will tell me which part of the db is growing so fast.

To give you an idea of how fast it is growing the db after truncating the logs and shrinking is less than 20Mb and at the end of the week it will be 350Mb. If I leave it a couple weeks it will freeze when it goes over 800Mb. Before adding the scheduled jobs it would grow twice as fast.

The install has 63 blog portals. I figured that the blogs must be creating more logs than the other portals as my other installs which are configured exactly the same don't behave this way.

Is this normal for blogs or is there some configuration which would improve this situation?

Thanks,

Pat

Hi Pat,

This is from the recovery modal your database is using. It sounds like your DB is currently using the Full modal. This can be changed to something like simple, however you need to be aware of the pros and cons. There is a article here that explains this a bit more.
