Azure Database cannot reduce the sizing from 750 to 500 GB.
Overall sizing after I checked in the Azure dashboard.
Used space is 248.29 GB.
Allocated space is 500.02 GB
Maximum storage size is 750 GB.
The validation message when I reduce the sizing:
Message is
The storage size of your database cannot be smaller than the currently
allocated size. To reduce the database size, the database first needs
to reclaim unused space by running DBCC SHRINKDATABASE (XXX_Database
Name). This operation can impact performance while it is running and
may take several hours to complete.
What should I do?
Best Regard
If we want to reduce the database size, we need to ensure the number of databse size is larger than the number of the Allocated space you set. Now, according to your need, we should reclaim unused allocated space. Regarding how to do it, we can run the following command
-- Shrink database data space allocated.
DBCC SHRINKDATABASE (N'db1')
For more details, please refer to the document
I got this error via CLI after also disabling read scale and the solution was to remove --max-size 250GB from command:
az sql db update -g groupname -s servername -n dbname --edition GeneralPurpose --capacity 1 --max-size 250GB --family Gen5 --compute-model Serverless --no-wait

We are using Azure SQL Database with 32 GB Storage. I have checked the storage utilization from Azure portal and it is showing me 68% used (22 GB). However, when I am trying to create an Index, I am getting the bellow error.
The database has reached its size quota. Partition or delete data,
drop indexes, or consult the documentation for possible resolutions.
Thanks.
Make sure the database does not have a maximum size set with the following query. This size limit is independent of the size limit of the tier.
SELECT DATABASEPROPERTYEX('db1', 'MaxSizeInBytes') AS DatabaseDataMaxSizeInBytes
You can change that max size to the limit of the current tier the database is using.
ALTER DATABASE CURRENT MODIFY MAXSIZE=100MB
Verify also the Azure SQL is not reaching the maximum size for the TempDB. Please visit this documentation to see the current limit for the service tier the database is using.
The Issue
I've been running a particularly large query, generating millions of records to be inserted into a table. Each time I run the query I get an error reporting that the transaction log file is full.
I've managed to get a test query to run with a reduced set of results and by using SELECT INTO instead of INSERT into as pre built table. This reduced set of results generated a 20 gb table, 838,978,560 rows.
When trying to INSERT into the pre built table I've also tried using it with and without a Cluster index. Both failed.
Server Settings
The server is running SQL Server 2005 (Full not Express).
The dbase being used is set to SIMPLE for recovery and there is space available (around 100 gb) on the drive that the file is sitting on.
The transaction log file setting is for File Growth of 250 mb and to a maximum of 2,097,152 mb.
The log file appears to grow as expected till it gets to 4729 mb.
When the issue first appeared the file grow to a lower value however i've reduced the size of other log files on the same server and this appears to allow this transaction log file grow further by the same amount as the reduction on the other files.
I've now run out of ideas of how to solve this. If anyone has any suggestion or insight into what to do it would be much appreciated.
First, you want to avoid auto-growth whenever possible; auto-growth events are HUGE performance killers. If you have 100GB available why not change the log file size to something like 20GB (just temporarily while you troubleshoot this). My policy has always been to use 90%+ of the disk space allocated for a specific MDF/NDF/LDF file. There's no reason not to.
If you are using SIMPLE recovery SQL Server is supposed manage the task of returning unused space but sometimes SQL Server does not do a great job. Before running your query check the available free log space. You can do this by:
right-click the DB > go to Tasks > Shrink > Files.
change the type to "Log"
This will help you understand how much unused space you have. You can set "Reorganize pages before releasing unused space > Shrink File" to 0. Moving forward you can also release unused space using CHECKPOINT; this may be something to include as a first step before your query runs.
I set JVM memory(JRE Parameter) size to 1024MB and by default it is 256MB. I inserted data into HSQLDB tables (size ~220MB) and i am getting the out of memory error on windows 7 machine. Though i set the size to 1024MB and i am still facing out of memory error. Please let me how to resolve this issue as this database is about to move into production site.
Any suggestion is greatly appreciated.
How do you know the size of HSQLDB tables?
The size of files that contain the database is not the same as the total Java object size of the database in memory. You can use CACHED tables for your largest tables to restrict the amount of objects loaded into memory.
I am moving around 10 million data from one table to another in SQL Server 2005. The Purpose of Data transfer is to Offline the old data.
After some time it throws an error Description: "The LOG FILE FOR DATABASE 'tempdb' IS FULL.".
My tempdb and templog is placed in a drive (other than C drive) which has around 200 GB free. Also my tempdb size in database is set to 25 GB.
As per my understanding I will have to increase the size of tempdb from 25 GB to 50 GB and set the log file Auto growth portion to "unrestricted file growth (MB)".
Please let me know other factors and I cannot experiment much as I am working on Production database so can you please let me know if they changes will have some other impact.
Thanks in Advance.
You know the solution. Seems you are just moving part of data to make your queries faster.
I am agree with your solution
As per my understanding I will have to increase the size of tempdb from 25 GB to 50 GB and set the log file Auto growth portion to "unrestricted file growth (MB)".
Go ahead
My guess is that you're trying to move all of the data in a single batch; can you break it up into smaller batches, and commit fewer rows as you insert? Also, as noted in the comments, you may be able to set your destination database to SIMPLE or BULK-INSERT mode.
Why are you using Log file at all? Copy your data (Data and Logfile) then set the mode on SIMPLE and run the transfer again.
I have a database that's taking up nearly 7 gigs. If I look at the table usage, it should be much less than that, like 40 megs. There was a large log table that I deleted yesterday, but my database still says it's very large.
Here are the stats:
database_name database_size unallocated space
Umbraco_Indoorpower 6911.56 MB 859.59 MB
reserved data index_size unused
31144 KB 26272 KB 3240 KB 1632 KB
I ran this:
DBCC SHRINKDATABASE (umbraco_indoorpower, 99);
And that got my database down to 2.3 gigs. Still though, way too large.
database_name database_size unallocated space
Umbraco_Indoorpower 2302.44 MB 1.63 MB
reserved data index_size unused
30016 KB 26200 KB 3240 KB 576 KB
I'm guessing I'm not freeing up all the space from that log table that I deleted yesterday. I actual ran delete from tblLog. Maybe that was the wrong way to go about it.
Does anyone know how I can free up some more space?
How big is the log file? What is your recovery model? It's quite possible that the database_size number above is nearly 7 GB of log and very little data. Find the files on your hard drive - you can locate the paths using:
EXEC umbraco_indoorpower..sp_helpfile;
I am going to bet that the LDF is HUGE and the MDF is actually small. In which case you are probably in FULL recovery model and have never taken a log backup. If this is true then you can do this:
USE umbraco_indoorpower;
GO
BACKUP LOG umbraco_indoorpower TO DISK = 'C:\some_path\umbraco.trn';
GO
DBCC SHRINKFILE(umbraco_indoorpower_log, 20); -- guessing on target MB size here
(If you are in simple recovery model, the above will fail, but there will be some other explanation why the log file is large - e.g. a long-running or uncommitted transaction, did your delete commit?)
Then you will want to either (a) set up proper maintenance, including full/diff/log backups, which will help make optimal reuse of the log file, or (b) switch to simple recovery, in which case the log will manage itself.
In most cases simple recovery does not provide enough protection in the event of a disaster, but that is for you to decide.
In the meantime, you can shrink the file all you want, but if you keep your recovery model and transaction handling the way it is, you'll just be seeing your file grow again and you'll be back tomorrow running the shrink command. This is absolutely horrible for your files. This is why I object to answers like "Run a shrink operation." I talk about why here:
Oh, the horror! Please stop telling people they should shrink their log files!
http://www.brentozar.com/archive/2009/08/stop-shrinking-your-database-files-seriously-now/
In any case, you have data and log, and for the log to be shrunk, you would have to have made a backup.
Edit: Everything Aaron said
The existing answers are already pretty good. I have one additional solution: Script the database including data (the SSMS UI allows you to do this easily) and execute the script in a fresh database.
You maybe want to switch to simple log model, too (if you don't have a special need for using the full logging model). One thing is for sure: You can't run in full mode and not have proper transaction log management.
Another thing that can take up more space in SQL Server is Service Broker queues. In my case I have 6 million rows in queues taking up 17GB...
