Questions About Recovery Models
Dec 5, 2007
Hello Everybody , I have Some questions and I am sure that this is the best place for them to not be questions any more.
Here are My Questions:
What is the difference between full recovery model and simple recovery model?
My database has an mdf file about 400mb and a log file about 5GB.
Is this caused because of full recovery model?
What can I do in order to make my log file smaller?
Which recovery Model Do you Suggest for Use and Why?
Thank you So Very Much
I sell my mother in law.Is anybody interested?

Hi,
If I'm using a transactional replication and the publisher's recovery model is se to FULL, can the subscribers use simple recovery model?
Thanks.

We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.

in the process of migrating a big db from server 1 to server 2, we had to roll back the change. I started with taking a full db backup and restoring it on server 2 with norecovery, and then a couple logs with norecovery, and then the last log with recovery.
Is there some way to continue this chain now, I mean to change the db to norecovery, or other way to restore logs.
I dont want to do a new full backup.
If I try to do a log restore now i get the message:
Msg 3117, Level 16, State 4, Line 1
The log or differential backup cannot be restored because no files are ready to rollforward.
Msg 3013, Level 16, State 1, Line 1
RESTORE LOG is terminating abnormally.

We have 3 replica AG setup. 2 replicas are in sync/automatic failover, the other(DR Server, different subnet) in asynchronous/manual mode…All these replicas were on sql server 2012, Recently we upgraded DR server to 2014. Since then we have a problem, the AG databases in 2014 instance went into ‘Synchronizing/ in recovery’ state…The SQL server error log has message, the recovery couldn’t start for the database ‘XYZ’…We tried to create a new database and add it to AG , it works for fine for other two 2012 replicas, but on 2014 we see the same issue

We have an issue with a 3 node SQL 2012 Always on availability group. Normal operation is node 1 (primary replica) with node 2 and node 3 as secondary replicas.After some patching, SQL wasn't running on node 1 hence the AG flipped over to node 2. This went unnoticed for some time and the transaction log for one of the AG databases became full on node 2 and node 3. (I think this is because it couldn't commit the transactions on node 1 so couldn't truncate it's t-log?) The DB is using synchronous replication btw.So I started SQL on node 1 and flipped the AG back to node 1 (with a data loss warning but I accepted this).Now the issue is that on node 2 and 3, the DB in question is stuck in a "Reverting / In Recovery" State. I've tried various commands such as ALTER DATABASE SET ONLINE, RESTORE DATABASE WITH RECOVERY etc but these fail stating unable to obtain a lock on the DB.
The weird thing is that on node 1 the state of the DB is "synchronised".how to resolve this issue on node 2 and 3? I've left them overnight (in case they were rolling back transactions, the DB is fairly large) but nothing seems to have happened. remove the DB from the AG in node 2 and 3 and add it back in again, ie recreate the replication?

If you are doing a disaster recovery of an entire SQL 2005 cluster, can you just install SQL server and restore the system database to get the configuration?

I have a Sharepoint integrated Reporting Services server. I have created Report models based on Data Sources. I then created Report Builder Reports to make some BI Charts and Graphs. They look great and work fine for a few days then all of a sudden I get a rsItemNotFound error saying it cannot find the Report Model which is clearly there.
An error has occurred during report processing. (rsProcessingAborted)
The item 'IT Reports/PWPDB_Prod_Model.smdl' cannot be found. (rsItemNotFound)
If I open the Report Model from Report Builder it loads the data fields, but also fails to run reports with the same error
If I try to regenerate the model from the library I get an error stating that the model needs to be a generated model.
The model specified must be a generated model.
(rsModelNotGenerated)
Even after rebooting all of the servers in the farm I get the same messages. I can regenerate a model from the data source and it doesn't work. I am seeing no errors in the logs of my app server at all regarding reporting services.
It looks as though I will have to de-integrate Reporting Services as it is not viable for a business critical application.

Need a little help here. I would like to utilize the ad-hoc capabilities of Reporting Services to grant the users of one of my web apps the ability to create all sorts of crazy reports that I don't have to develop.
Basically, this web app is a flexible survey engine. My vision is to have the users select questions from a survey that they wish to generate statistics on. My application would create a view in the database that transposes the data into a tabular format. They would then get kicked over to the reporting services web client, where they can regenerate a report model, and then fire up report builder to create their crazy statiscal abomination. (Aren't users grand!)
This process sounds wonderful, but I'm not aware of any way to get the report model to regenerate and pickup any views. I can get it to pick up any new tables that are added as long as a primary key is created for them, but I want the automated dynamic data rendering that comes with a view. Hopefully, some of you out there have tried to do this already and have some ideas that may help me. Thanks!

Hello
I've created models with Decision Tree and Neural Network algorithms that predict continous target. But I don't know how to interpret scores that occure under scatter accuracy plot. How should I interpret scores under scatter accuracy plot?
How can I estimate occuracy of model created with Time Series? How can I compare accuracy of model created with Time Series with models created with Decision Trees and Neural Network algorithms?
Thanks in advance.

Hi, guys,
Thanks for your kind attention.
Just want to make things perfectly work and make the most of our fantastic SQL Server 2005 Data Mining Engine. Can any of you here give me some super advices on the validation of the mining models. As we always see, the 3 aspects of a mining model are: Score, Population correct, and Predict Probability. So the question is: How can we combine these three aspects to best judge the mining models by being able to tell which model is the best one? And to what extent can we really trust these mining models?
These are very important before we can actually bring the models into work to convince other people who have no ideas what are going on with these models. Yes, we just want to convince them with the results of these models and make the most of them and best help them getting the most from their business operations etc.
By the way please can you explain a bit details on each of these aspects? Thanks again.
I am looking forward to hearing from you shortly and thanks bunch for your help.
With best regards,
Yours sincerely,

I am having a problem deploying or manually uploading smdl files to reporting services. I can upload anyother type of file without a problem. (dsv, ds, etc.) However, when i try to upload a smdl file, I get
"The permissions granted to user '<me>' are insufficient for performing this operation. (rsAccessDenied)"
How do I fix this?
Thank you"

I've been experimenting with the algorithm parameters for a market basket association model. The default MINIMUM_ITEMSET_SIZE is 1. This doesn't seem to make sense: what is the point of a single-member itemset? However changing the value to 2 substantially reduces the proportion of good recommendations obtained (which I'm testing via a holdout approach).
So I'm obviously misunderstanding what the parameter means. Can someone explain it please, and also explain the observation above)?

Hi, all here,
Since we are not able to use accuracy chart for Clustering algorithms there. So how can we verify the accuracy of clustering algorithm models here in terms of its classification and regression tasks?
Thank you very much in advance for your guidance and advices for that.

Yours sincerely,

Using SQL Server 2005 Business Intelligence Studio, I created a Data Source (Test.ds), Data Source View (Test.dsv), and a Report Model (Test.smdl). It is very easy to deploy this model into a Report Server, from the Business Intelligence Studio, by right clicking the Report Model Project and choosing 'Deploy'.

I am have a few reports built in Report Builder and obviously using Report Models. All these report models are using a share data source. When I try enable to enable chache or creating subscription I get and error that "Credentials used not stored".
I thought well let me store the credentials for the data source used by the model used by the report on the server. I still get the same error.
I tried to create a custom data source for the report but there is not option for connection string to connect to Report Server Model. We have "Microsoft SQL SEVER", "OLE DB", "Microsoft SQL Analysis Services", "ORACLE", "ODBC", "XML", "SQP Netweaver BI" and "Hyperion Essabe"
if I understand this right to create cache or subscription I must store the credentials for each report making shared Data source concept redundant. Also I cannot create a connection string to connect to Report Server Model.
I would greatly appreciate if anyone can tell me how to enable cache or subscriptions for report that are built on report models using shared data source.

Hi, all here,
I am having a question about automating data mining models managements. As we know in many businesses, patterns vary very frequently, therefore, the mining models created will need to be created again afterwards according to new rules appearing in the data. But can we make all these process automated like automatically assessing the mining model accuracy and automatically recreate the mining models based on predifined specifications? Would please any one here give me any idea about that?
Thanks a lot for any guidance and help for that.
With best regards,

How does the report model know what data source view to use? I could not find it defined anywhere in the .smdl file.
My problem is this. I have a Report Model project with two data sources, two data source views and multiple report models. When I try and bind a data source to an entity in the report model I do not get to choose which data source view to use to choose what table/view I want to bind the entity too and only the tables in one of my DSV's shows up. When I first created it, it worked fine. It automatically selected the correct view and table and was successfully created but now when I open the project, that correlation is lost.
Any suggestions or help is appreciated, thanks.

Hi All
I have been asked by developers if there is any advantage in processing multiple clustering models simultaneously by using AMO and multiple threads as against processing one after another.
I have limited experience with Analysis Services but based on my reading I don't see this method providing any advantage.
Does anyone have any recommendations or advice? The system Enterprise Edition running on an x86 Server with 2 dual core processors and 4GB of RAM. Would the answer alter if the server running x64 version of SQL Server and Windows.
Thanks

Hi, all,
Again I am confused about the extent of being convinced by the mining models. We can validate the models with accuracy chart, but then to what extent can we trust that? (you never get 100% correct miming models) If we dont trust the results of the models, then the patterns the models discover are meaningless.
Just need some advices from you experts here to help me convince people on what I got from my mining models.
I am looking forward to hearing from you shortly and thank you very much.
With best regards,
Yours sincerely,

I am in the process of creating an Integration Services package to automate the process of training mining models and getting predictions. Until recently, I have been processing the models directly from Business Intelligence Studio without any problems. However, when I try to use the exact same training set as an input to the Data Mining Model Training destination, I get several errors. Here is the output:
[Mining Models [1]] Error: Parser: An error occurred during pipeline processing.
[Mining Models [1]] Error: Errors in the OLAP storage engine: The process operation ended because the number of errors encountered during processing reached the defined limit of allowable errors for the operation.
[Mining Models [1]] Error: Errors in the OLAP storage engine: An error occurred while the 'CPT MODIFIER' attribute of the 'BCCA DMS ~MC-CLAIM LIN~5' dimension from the 'BCCA LRG DMS TEST' database was being processed.
[Mining Models [1]] Error: File system error: The record ID is incorrect. Physical file: . Logical file: .
[Mining Models [1]] Error: Errors in the OLAP storage engine: The process operation ended because the number of errors encountered during processing reached the defined limit of allowable errors for the operation.
[Mining Models [1]] Error: Errors in the OLAP storage engine: An error occurred while the 'BILL TYPE' attribute of the 'BCCA DMS ~MC-CLAIM LIN~5' dimension from the 'BCCA LRG DMS TEST' database was being processed.
[Mining Models [1]] Error: File system error: The record ID is incorrect. Physical file: . Logical file: .
[DTS.Pipeline] Error: The ProcessInput method on component "Mining Models" (1) failed with error code 0x80004005. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
I have not been able to find an answer as to why this is happening. I found a post regarding a similar problem with processing an OLAP cube in SSIS, but it seems that the author of that post never found an answer. Has anyone else here seen similar errors when processing mining models from Integration Services?
Also, if I process the mining models manually then try to run only predictions in SSIS, I get many of the same errors. I'll keep looking into the problem myself, but I would be very grateful if someone in this forum could shed some light on this issue.

Hi, all experts here,
Thank you very much for your kind attention.
I got a strange problem with SQL Server 2005 data mining models though. I have selected the input columns for my mining model (which are different from the input columns for its mining structure, since I ignored some of the columns for the selected model). But the mining model still used all input columns from the mining structure rather than those I chose for the mining model.
Would please any one here give me any guidance and advices for that. Really need help for that.
Thanks a lot in advance for any help.
With best regards,
Yours sincerely,

Hi!
If you make an view you can script it in SSMS and get the DDL.
How to do something similar with mining models/structures getting DMX?
I see you easy can get XMLA, but I would prefer the "dmx-ddl"...
Thanks
Bjorn
