Transaction Log Full Due To Poorly Configured SQL Database
Dec 23, 2005
Good evening all,
I am new to Microsoft SQL and have been dumped right into the deep end with an anchor around my ankles.
The problem I am experiencing is about 6 months back a guy setup a Microsoft SQL server at my client. He then took his bags and left. Then a developer developed an application which uses a database on this sql server. Everything worked well for around 4 months.
Yesterday IBM Director notified me that I am running dangerously low on disk space on the server. By the time I came in to work this morning I had 12mb free disk space. The evil thing here is the transaction log for the downtime database. It has grown to over 60gb, all because the correct measures were not implemented to prevent this.
The problem that is occuring is no one can do anything on the database now due to the lack of free space. I have tried reading the sql books online but due to my lack of sql experience and knowledge I am stuck.
Can someone please help me? What I would like to do is pull my transaction log down to an acceptable size.
I was thinking of creating a new database and then importing all the data from the current database and then just deleting the current database however am slightly concerned that this may result in some data being lost.
Thanks in advance,
Richard

I have a Access database which has a address field with multiple data sets in it. I am new to writing code and am having trouble finding a example which will help me split these values out into three seperate fields.
Notice how there is no good order in how they are placed.... Some entry's have commas and some don't. Some have periods and some don't.
EX:
[BILL_ADDR3]
AMHERST, WI. 54406
ASHLAND, WI 54806
ASKOV MN 55704
I then need to convert the state to a state code ie:
2 AK
3 AL
4 AR
5 CA
6 CO
7 CT
8 DC
9 DE
10 FL
11 GA
12 HI
13 IA
14 ID
15 IL
16 IN
17 KS
18 KY
Any good sources of information would be greatly appreciated..... Thank You

One of the primary parts of my job is working with the SQL database of our Enterprise ERP software. One of my primary responsibilities is writing reports based on it's data and since it is not well documented and this is one of my biggest challenges. To top it all off, it's hard to even use their reports to learn the links between tables as the reports run completely in Visual Foxpro.
Is there reasonably priced software that will analyze the database for me and make it easier for me to figure out the relationships between certain tables and such?
TIA,
Dave

System.Data.SqlClient.SqlException:
The transaction log for database 'mydatabase' is full. To find out why space
in the log cannot be reused, see the log_reuse_wait_desc column in
sys.databases I have my website on a web hotel and I only have limited access to my database. How can I solve this for now, and the future??

SQL2005 SP2+Cum.Patch Rrevision 4 (9.0.3175)
I always get this message, when i want to run a stonger query or a transaction that takes a longer time:
"The transaction log for database 'tempdb' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases"
I checked the log_reuse_wait_desc column: LOG_BACKUP
I ran tr log backup...nothing...
I tried to set to simple reco mode the db...this helped... temporaly...i got again below message.
( i wouldn't like to set to simple mode the db because the size of db is 160GB now....so i don't want to eun a fullbackup)
TempDB size is 50MB now and it can grow until 7GB.
The trqansaction log size is 14GB and there are 50GB free space, so it can grow.
This symptom occurs since i installed SP2 and the CP Rev.4.0
What is the real problem ?

We had a siutation last night in our production environment that forced us to revert back to an earlier version of the database (before a major code rollout that failed). After restoring the days full backup (with NORECOVERY), and then restoring a DIFF backup (FULL RECOVERY and had checked Preserve Replication Settings)...the transaction replication failed.
Message #1
The replication agent has been successfully started. See the Replication Monitor for more information.

I've tried reinitializing the publication/subscription and while that took brand new snapshots and copied it over to the replicated data server, it did not fix the problem.I read from a different post that I could try running "sp_replrestart" but that ran for about a half an hour and didn't appear to do anything but fill up our log files...did I not wait long enough?
The only thing I know to do at this point is to drop the publication on the production server and rebuild it completely (and with all the tables we're replicating that would take quite a bit of time.

Hello,
I am developing a smart device application with Visual Studio .Net 2005 and SQL Server Compact Edition database. And also using merge replication to synchronize the data from the mobile device to the SQL Server.
My database size is around 350MB. So when I am trying to synchronize this is the error message that I get.
" The database file is larger than the configured maximum database size. The setting takes effect on the first concurrent database connection only.[Required Max Database size ( in MB; 0 if unknown)=129].
I tried changing the Max database size in the connection string and my connection string looks as follows and still did not have any luck.
connstr= "Data Source=Storage CardItems.sdf;Max Database Size=500;"
Any help regarding this would be appreciated.
Thank you
.

We take a full backup in the early morning and hourly transaction log back during the working hours for one database in the production server. The application team made certain changes to the design of the said database in their development server. The backup from the development server was restored to the production server during working hours. After the restoration should we take a full backup before next transactional logbackup? Would the transactional log backup with out a full backup after the restoration of a database be valid?

Need to confirm if we can add space(increase data file size) for the database which is configured for always on similar to that of mirroring or we need to follow any different procedure.
I have a requirement wherein the datafiles on both the primary and secondary replica got full, if i add space to the primary database will it automatically get added to the secondary replica or not?

I'm running the same query on two computers but getting a different query plan. On one of the servers, the query returns in 10 seconds, on the other server it takes over a minute. What the heck!
1. same hardware configuration on both computers
2. same user databases on both computers
3. same NT setup on both computers
4. same software installed on both computers
I can only imagine that MSSQL7 was setup differently and the query optimizer is making a stupid choice. I've compared numerous SQL server options and they are both the same.
1. sp_configure (same on both computers)
2. properties sheet on each server from enterprise manager (same on both computers)
any ideas???

I'm working with a database that is poorly normalized and am doing my best to increase the speed of our queries (changing the database itself is not an option right now). Any help with the following situation would be very much appreciated.
There are two tables involved, described below.
DataTable:
Code Snippet
CodeA char(4),
CodeB char(4),
CodeC char(2),
ColA float,
ColB float,
ColC float,
...
ColZ float
NameTable:
Code Snippet
Abbr char(2),
FullName varchar(50)
In the DataTable, the columns named ColA, ColB, ColC, etc., are described in the NameTable where Abbr would be A, B, C, etc., and FullName would be a "nice" text version describing what's stored in that column. For instance, a record in the NameTable might include Abbr = 'A' and FullName = 'Computer Science', and that means that ColA in the DataTable refers to 'ComputerScience'.
The table I'm trying to optimize the creation of in our ASP.NET application needs to have column headings that could be retrieved like this:
SELECT DISTINCT CodeB, CodeC FROM DataTable WHERE CodeA = @CodeA
(Note that CodeC is really just a different representation of CodeB--think 4-digit year vs. 2-digit year--for any given CodeA.)
The row headings for the table could be retrieved like this:
SELECT FullName FROM NameTable
The cells of the table at any given intersection of a row heading and a column heading can be retrieved like this:
SELECT Col? FROM DataTable WHERE CodeA = @CodeA AND CodeB = @CodeB (this selects a single value)
Where the ? of Col? is determined by the Abbr version of FullName shown in the row heading, and @CodeB is determined by CodeB from the column heading.
Right now this table is generated using a lot of loops in the code of the page that require it to query the database for nearly every cell in the table. Even with this poor database design, there has to be a better way than that. I'm hoping there is a way to create a stored procedure that uses temporary tables and joins, or views, or something like that to create the table on the SQL Server and just send the data to the ASP.NET page in a form that can be directly databound to a GridView.
Thanks in advance for any help!

I have a transaction log which is 1 Gb and only has about 40 Mb free. When I run DBCC loginfo I find the first active log dates back to the middle of August. Does any one have any suggestions on the best way to approach this situation. How can I query the transaction log to find out what the old transactions are? I was going to use the detach database, rename log, attach database to shrink the log but don;t want to do this incase there is active data in the log. We are doing hourly log dunps.
Thanks

Hi there,
I'm still fairly new to SQL server and I've just ran into a problem when dropping some tables from my DB as my transaction log has become full. I looked at books online and it basically said to backup the log so it will also truncate the log. However I've ran out of disk space on my data drive so can't take a backup.
Is there a way to just truncate the active log to shrink the size?
Hope you can help??
Thanks

Today, one of our backups failed due to the transaction log being full. I expanded the transaction log and then the backup completed normally. For a short term resolution, I increased the maximum allowed size on our transaction log files.
We are doing a database backup only as follows:
backup database xxxxx to xxxx_data with init
I did find a note stating that the transaction log will eventually become full if doing a transaction log backup only. We do not generate a lot of transactions so I had not seen a need to backup the log during the day. The full database backup is done daily.
My question is, in order to permanently resolve this error do I have to:
- take a transaction log backup as well. Should I take it take right after the full database backup or at some later point.
- do I have to schedule/run the shrink database command.

I was trying to create a table on a Database and it gave me this message:
'tblSuggestion' table - Unable to create table. The transaction log for 'Database' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
And I don't see the log_reuse_wait_desc column anywhere.
Any ideas?

Hi,
At the start, transaction log size is 1MB. at the middle of the dts it reached to nearly 2 GB. I encountered this error in DTS:
OnError,,,CallerType, CallerChannel, Dealer, DODealer, HotlineType, Model, Reg'l Signal Code, Account, Contact,,,10/22/2007 10:55:43 AM,10/22/2007 10:55:43 AM,-1071636471,0x,SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E14.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E14 Description: "The transaction log for database 'DB1' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases".
I visited the sys.database's log_reuse_wait_desc and it is set to checkpoint.
The transaction log keeps getting full in the middle of the dts, not enough to do the 1 round execution of the dts. What to do with this one? Anything that i need to add in my dts to truncate the logs?

hi,
if my transaction log is full, do i need to execute only this command to truncate old logs?
DBCC SHRINKFILE(<dbname>, 1)
BACKUP LOG <dbname> WITH TRUNCATE_ONLY
DBCC SHRINKFILE(<dbname>, 1)
Should I use the same command as a daily maintenance to my transaction log?
