SAP Technical Content - Transaction Logs are overflowing

Hi,
We activated the SAP TC on Friday and on Monday our transaction log was full.
In Transaction RSDDSTAT on the Query Tab we activated logging for every query but is this really the reason? There was almost no activity on the system during the weekend and this would be very odd.
I couldn't find any relationship between the TC and the transaction log but there must be something.
Thx for any hint

Hi Christian,
Did you check the active jobs in SM37?

Install SAP Technical Content

I have heard about installation of Technical Content.
Can any one tell me how to install SAP Technical Content and why we used it.

Hi
After a new install or upgrade, Technical Content will be installed automatically after you run TCODE Rsa1 (BI_TCO_ACTIVATION) for the first time. It is used for the BI Stats and authorization to mention a few.
See OSS note 979581 for more details.
Thanks

How to find out whether the transaction logs are being truncated or not

Hi,
We are using Veritas Backup tool for Backups and restores on our MS SQL 2000.
One of our Veritas Tech has disabled the Truncation of Transaction Log Backup using the Job setup in Veritas. We want to confirm whether the Truncation is happening or not. I don't see any difference in the Transaction Log file size.
How to find out whether truncation is active or not?
Thanks
Vijay

Hello Vijay,
On MSSQL truncation of transaction log does not shrink the size of the transaction log. It simply removes the content within the transaction log and writes it to the backup.
Meaning the free percentage within the transaction log will increase.
If you want to Resize the transaction log size, you need to do something else.
The shrinking procedure is given here:

Content database transaction log is full

Hi guys,
i am facing some very serious issues right here, SharePoint content can't be updated because the transaction log drive for the logs is full. the following message is displayed in the event viewer
'The transaction for database wss_content_guid is full. To find out why space can't be reused see the log_reuse_wait_desc column in sys.databases'
Pls help

Hi,
The recommended way to truncate the transaction log if you are using a full recovery model is to back up the log. SQL Server 2005 automatically truncates the inactive parts of the transaction log when you back up the log. It is also recommended that you pre-grow the transaction log to avoid auto-growing the log. For more information about growing the transaction log, see Managing the Size of the Transaction Log File (http://go.microsoft.com/fwlink/?LinkId=124882). For more information about using a full recovery model, see Backup Under the Full Recovery Model (http://go.microsoft.com/fwlink/?LinkId=127985). For more information about using a simple recovery model, see Backup Under the Simple Recovery Model (http://go.microsoft.com/fwlink/?LinkId=127987).
We do not recommend that you manually shrink the transaction log size or manually truncate the log by using the Truncate method.
Transaction logs are also automatically backed up when you back up the farm, Web application, or databases by using either the SharePoint Central Administration Web site or the Stsadm command-line tool. For more information about the Stsadm command-line tool, see Backup: Stsadm operation (Windows SharePoint Services).
So I would suggest you backing up SharePoint by either the SharePoint Central Administration Web site or the Stsadm command-line tool.
For more information about Best Practice on Backups, please refer to the following articles:

Urgent-Issue with Technical Content.

Hi experts,
we have activated the technical content.Now we are Initilize and run deltas with Process Chain.
Under one of the Infosource loading the datatarget(0BWTC_C02),i have the following standard delivered infopackages
1) Delta - OLAP Transaction Data
2) OLAP Transaction Data Initialization
3) OLAP Transaction Data: Delta Initialization
4) Transaction Data OLAP - Delta
5) Transaction Data OLAP - Delta Initialization
I have checked all these infopackages,i dont see any difference when i tried to compare the selection conditions and datatargets.
Now my question is
1) How do i select which infopackage should be in the process chains?
2) Also do we need to create and delete indexes for the technical content cubes too?
Please advise
thanks in advance
kiran

Hi sunil,
I appreciate your reply.
Issue 1:My question was as i have 5 Standard infopackages with no differences.If you see my first posting.How should i consider which infopackage to choose for in my Process Chain?
Ex: As i see 3 Init Infopackages witht he same name.How should choose which onfopackage to include for the process chain?
Also i see 2 delta infopackages witht almost the similar name.How should i consider which infopackage to include for the process chain.
Issue 2: I do understand that indexes are deleted before loading data for better loading performance and then indexes are created for reporting perfomances.
But my question was do we have to create/delete indexes for Technical content too.What is the recommended solution?What are the Pros and Cons?
Hope i am clear with my questions this time.
thanks in advance

Whether t-logs are truncated in DB's particpating in High Availability. SQLAlways On 2012

Hi,
How the transaction logs are cleared for DB's participating in SQL AlwaysOn.I have a DB participating in HA.Now in order to use alwaysON DB recovery model should be set to full. NOw with this recovery model my transaction logs will grow continuously.
How t-logs can be cleared for the DB's participating in AG. Is there any recommendation?
Thanks
Manish

Hello,
Have you scheduled log backup on primary.Secondary replica might be applying transaction log records of this database to a corresponding secondary database.
Whats does below query returns
select name,log_resuse_wait_desc from sys.databases where name='db_name'

Very high transaction log file growth

Hello
Running Exchange 2010 sp2 in a two node DAG configuration. Just recently i have noticed a very high transaction log file growth for one database. The transaction logs are growing so quickly that i have had to turn on circular logging in order to prevent
the log lun from filling up and causing the database to dismount. I have tried several things to try find out what is causing this issue. At first i thought this could be happening because of virus, an Active Sync user, a users outlook client, or our salesforce
integration, howerver when i used exmon, i could not see any unusual high user activity, also when i looked at the itemcount for all mailboxes in the particular database that is experiencing the high transaction log file growth, i could not see any mailboxes
with unusual high item count, below is the command i ran to determine this, i ran this command sever times. I also looked at the message tracking log files, and again could see no indication of a message loop or unusual high message traffic for a
particlar day. I also followed this guide hopping that it would allow me to see inside the transaction log files, but it didnt produce anything that would help me understand the cause of this issue. When i ran the below tool againts the transaction log files,
i saw DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD, or OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO, or HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH.
I am starting to run out of ideas on how to figure out what is causing the log file build up. Any help is greatly appreciated.

If you have users with iPhones or Smart Phones using ActiveSync then one of the quickest ways to see if this is the issue is to have users shot those phones off to see if the problem is resolved. If it is one or more iPhones then perhaps look at
what IOS they are on and get them to update to the latest version or adjust the ActiveSync connection timeout. NOTE: There was an issue where iPhones caused runaway transactions logs and I believe it was resolved with IOS 4.0.1
There was also a problem with the MS CRM client awhile back so if you are using that check out this link.
http://social.microsoft.com/Forums/en/crm/thread/6fba6c7f-c514-4e4e-8a2d-7e754b647014
I would also deploy some tracking methods to see if you can hone in on the culprits, i.e. If you want to see if the problem is coming from an internal Device/Machine you can use one of the following
MS USER MONITOR:
http://www.microsoft.com/downloads/en/details.aspx?FamilyId=9A49C22E-E0C7-4B7C-ACEF-729D48AF7BC9&displaylang=en and here is a link on how to use it

And this is a great article as well
http://blogs.msdn.com/b/scottos/archive/2007/07/12/rough-and-tough-guide-to-identifying-patterns-in-ese-transaction-log-files.aspx
Also check out ExMon since you can use it to confirm which mailbox is unusually active , and then take the appropriate action.

Moving Exchange 2010 Transaction Log

Hi. Running a single instance of SBS2011 with Exchange 2010. We only have one mailbox.
Earlier today I moved our main exchange database (.edb) file to a different hard drive. Used EMC, went through smoothly, no issues.
I then started moving the transaction logs. Same process:
Exchange Management Console > Organization Configuration > Mailbox > Move
Database Paths
This appeared to be going fine but after 40 mins came up with an error along the lines of "WinRM cannot process the request in the time specified"
Now I cant access any mailboxes. OWA giving the error - Your mailbox appears to be unavailable. Try to access it again in 10 seconds. If you see this
error again, contact your helpdesk
I have checked in EMC and the mailbox is successfully mounted. I have restarted all exchange services.
I also now have 8.5GB of log files in the "new" location. Not if these are just copies or exchange is actually using this drive.

Hi:
I think you may be over complicating this. SBS includes a wizard in the SBS Console to move most/all of the user impacted data stores, including Exchange, SharePoint, WSUS and Redirected folders. The transaction logs are limited in size if you
use either the SBS backup or a third party backup that is "Exchange Aware" to backup the server or the Exchange subsystem, so there is really no need to move the logs, assuming you are making good backups.

Transaction logs filling

Hi,
Our transaction logs are getting filled up very rapidly. Within two hours of time about 60 GB of transactions logs
are getting filled. But the users activity is not that high and very normal.
As I am new to MSSQL, kindly guide us in this regard.
Best Regards,
DVRK

Hi Rama,
Are you doing any client import process or any other process that cause filling the Transaction logs .
Go to SM37 and see the Acive jobs and check out any backgroung jobs running continuous causing this issue .
Also go to SM50 and see any long runnning activities going on .
To Free up Transaction logs space you can follow any of the below options :
1) Take Backup of Tlogs , it will work out and some free space will be generated.
2) You can shrink Transaction log . Refer note : 625546

Cleaning up transaction logs on a CE507/560

Hi,
We are exporting the CE transaction logs to an FTP server.
Is there any function on the CE that will delete any transaction log that has been FTP'ed off of the box?
Thx.

HI,
I could not copy the archived transaction logs to the ftp server, here is the message i received every time:
Jun 08, 2004 12:45:29 Session 25, Peer xx.xx.xx.xx 550 temp : No such file or directory.
i cannot specify the directory to which the transaction logs are copied.
Can you give me a detailed example explaining how to define the ftp directory. i'm using 3cdaemon ftp server.
Regards

WebDAV Query generates a high number of transaction log files

Hi all,
I have a program that launch WebDAV queries to search for contacts on an Exchange 2007 server. The number of contacts returned for each user's mailbox is quite high (about 4500).
I've noticed that each time the query is launched, about 15 transaction log files are generated on the Exchange server (each of them 1Mb). If I ask only for 2 properties on the contacts, this number is reduced to about 8.
This is a problem since our program is supposed to launch often (about every 3/5min) as It will synchronize Exchange mailboxes with a SQL Server DB. The result is that the logs increase very quickly on the server side, even if there are not so many updates.
Any idea why so many transaction logs are generated when doing a WebDAV search returning many items? I would understand that logs are created when an update is done on the server, but here it's only a search with many contacts items returned.
Is there maybe a setting on the Exchange server to control what kind of logs to generate?
Thank for your help,
Alexandre

Hi Alex,
Actually circular logging/backup was not a solution, I was just explaining that there is an option like that on server but it is not recommended hence not useful in our case :)
- I am not a developer but AFAIK, WebDAV search query shouldn't generate transaction log because it just searches the mailboxes and gives the result in HTTP format and doesn't produce any Exchange transaction.
- I wouldn't open transaction logs since it is being used by Exchange which may generate errors and may corrupt Exchange database sometime too. However it is not readable, as you observed, other than Exchange Information Store service (store.exe).
- You can post this query in development forum to get better idea on this, if any other programmer observed similar symptom while using WebDAV contact search query in Exchange 2007 or can validate your query.
Microsoft TechNet > Forums Home > Exchange Server > Development
Well, I just saw that you are using Exchange 2007, in that case why don't you use Exchange Web Service which is better and improved method to access/query mailboxes where as WebDAV is also de-emphasized in Exchange 2007 and might be disappeared in next version of Exchange. Checkout below article for further detail.

Transaction Logs Troubleshooting

Hi,
I have recently deployed a brand new Exchange 2013 scenario for a customer and the exchange system is working well but I have found the transaction logs are growing at an extra ordinary rate and I'm struggling to troubleshoot the issue.
There are two Exchange servers in this deployment with a WAN connection between the two locations. I have also setup a DAG with a copy of the database at both locations.
The Mail flow is good users are using the system.
This issue only applies to one of the Exchange servers where the transaction logs are being created at about 1 every 5 seconds. There are only about 12 Mailboxes in each location so I see no reason for so many transactions taking place.
I have tried to locate whats causing the issue and have tried to use ExMon but this doesnt appear to work with Exchange 2013. The only bit of useful information I have found was to use this:
http://blogs.technet.com/b/exchange/archive/2012/01/31/a-script-to-troubleshoot-issues-with-exchange-activesync.aspx
where it did show there was one particular Android device that had a very high Hit count. I have asked the user to disable the device's email for the time being while I investigate further but the transaction logs are still growing.
From the same results I also see the Healthmailbox's have high hit numbers.
The script also has a line with some 55000 hits but its user is blank. What is this likely to be?
Is there a tool I can use to help me identify whats causing these logs to grow so fast?
I have installed some backup software to run every night that helps reduce the logs and also enable circular logging which I understand will help prevent running out of space on the drive.
Would really appreciate some guidance.
Thanks
Bill

Do you have any third party software AV installed on Exchange mailbox servers. If so can you disable them for a while or set exclusions for Exchange files on them.
Check the queue and see if there are any emails stuck in the queue
Just run below command to check if there are any large emails with attachment stuck in any of the users mailbox which might cause the issue
get-mailbox -ResultSize Unlimited| Get-MailboxFolderStatistics -folderscope Outbox | Sort-Object Foldersize -Descending | select-object identity,name,foldertype,itemsinfolder,@{Name="FolderSize MB";expression={$_.folderSize.toMB()}} | export-csv OutboxItems.csv
In your case most likely any third party AV might be causing this. Just disable third party AV if any and check.

Cannot write to transaction log "C:\Program Files (x86)\SAP BusinessObjects\sqlanywhere\database\BI4_Audit.log

Hi friends,
My server Intelligence Agent (SIA) can not start because the database service "SQLAnywhereForBI" can't start also. I got the following error :
"I . 08/09 20:35:06. A read failed with error code: (1392), Le fichier ou le répertoire est endommagé et illisible.
E. 08/09 20:35:06. Fatal error: cannot write to transaction log "C:\Program Files (x86)\SAP BusinessObjects\sqlanywhere\database\BI4_Audit.log"
E. 08/09 20:35:06. unable to start database "C:\Program Files (x86)\SAP BusinessObjects\sqlanywhere\database\BI4_CMS.db"
E. 08/09 20:35:06. Error writing to transaction log file
I. 08/09 20:35:06. Database server shutdown due to startup error "
inside the database log file.
Please, can you help me

I found the solution by following the advice given on the following forum:
http://evtechnologies.com/transaction-logs-on-sybase-sql-anywhere-and-sap-businessobjects-bi-4-1
In fact, I crushed the BI4_Audit.db and BI4_Audit.log files and I replaced with others that I got from another machine where I installed BO again and where the files are not corrupted . After I logged in to the CMS database by executing the command in the command line:
dbisql -c "UID = DBA; PWD = mypassword; BI4 Server =; DBF = C: \ Program Files (x86) \ SAP BusinessObjects \ sqlanywhere \ database \ BI4_CMS.db."
Once connected, I start the command:
alter database 'C: \ Program Files (x86) \ SAP BusinessObjects \ sqlanywhere \ database \ BI4_Audit.db' alter log off;
The query runs successfully.
And that's good, I can be connected to BO smoothly.
Thank you again Eric

Content Engine transaction logs -- monitoring and analysis

At our remote sites there's a local Cisco CE511 to ease our WAN bandwidth. I have been tasked to find a method to gather CE usage for trending and troubleshooting.
From my search on the internet I decided to go with the Webalizer application. I setup the CEs to export their transaction logs every hour to my FTP server. After a test of Webalizer on a log file, it produced a nice HTML report for that hour.
I would like to discuss with anyone on bringing this up to a new level. I would like webalizer to run as a cron job, but the log file names changes every hour. So that's a hurdle I need to figure out. Also keeping track of user web hits is important. I would like to make sure my reports are accurate in reporting what IP address is the top talker.
I hope this will start a productive exchange of ideas. Thanks.

Simple Network Management Protocol (SNMP) is an interoperable standards-based protocol that allows for external monitoring of the Content Engine through an SNMP agent.
An SNMP-managed network consists of three primary components: managed devices, agents, and management systems. A managed device is a network node that contains an SNMP agent and resides on a managed network. Managed devices collect and store management information and use SNMP to make this information available to management systems that use SNMP. Managed devices include routers, access servers, switches, bridges, hubs, computer hosts, and printers.
An SNMP agent is a software module that resides in a managed device. An agent has local knowledge of management information and translates that information into a form compatible with SNMP. The SNMP agent gathers data from the Management Information Base (MIB), which is the repository for information about device parameters and network data. The agent can also send traps, or notification of certain events, to the manager.
