            You can only select a single database from your source to migrate to the Azure SQL database using the Data Migration Assistant tool.

            You can create an Azure Database Migration Service resource in the Azure portal and select one or more databases to migrate from SQL Server to Azure SQL Database.

            Oracle to Postgres Table load using SSIS load performance improvement suggestions?
            Asked 2022-Feb-20 at 09:22

            I'm trying to load a table from Oracle to Postgres using SSIS, with ~200 million records. Oracle, Postgres, and SSIS are on separate servers.

            Reading data from Oracle

            To read data from the Oracle database, I am using an OLE DB connection using "Oracle Provider for OLE DB". The OLE DB Source is configured to read data using an SQL Command.

            In total there are 44 columns, mostly varchar, 11 numeric, and 3 timestamps.

            Loading data into Postgres

            To lead data into Postgres, I am using an ODBC connection. The ODBC destination component is configured to load data in batch mode (not row-by-row insertion).

            SSIS configuration

            I created an SSIS package that only contains a straightforward Data Flow Task.

            Issue

            The load seems to take many hours to reach even a million count. The source query is giving results quickly while executing in SQL developer. But when I tried to export it threw limit exceeded error.

            In SSIS, when I tried to preview the result of the Source SQL command it returned: The system cannot find message text for message number 0x80040e51 in the message file for OraOLEDB. (OraOLEDB)

            Noting that the source(SQL command) and target table don't have any indexes.

            Could you please suggest any methods to improve the load performance?

            ...

            ANSWER

            Answered 2022-Feb-20 at 09:22

            I will try to give some tips to help you improve your package performance. You should start troubleshooting your package systematically to find the performance bottleneck.

            Some provided links are related to SQL Server. No worries! The same rules are applied in all database management systems.

            1. Available resources

            First, you should ensure that you have sufficient resources to load the data from the source server into the destination server.

            Ensure that the available memory on the source, ETL, and destination servers can handle the amount of data you are trying to load. Besides, make sure that your network connection bandwidth is not decreasing the data transfer performance.

            Make sure that the following hardware issues are not occurring in any of the servers:

            1. Drive out of storage
            2. Server is out of memory

            Make sure that your machine is not running out of memory. You can simply use the Task Manager to identify the amount of available memory.

            2. The Data Source Make sure that the table is not a heap

            After checking the available resources, you should ensure that your data source is not a heap. At least it would be best if you had a primary key created on that table.

            Indexes

            If your SQL Command contains any filtering, ordering, or Joins, you should create the indexes needed by those operations.

            OLE DB provider

            Instead of using OLE DB source to connect to Oracle, try using the Microsoft Connector for Oracle (Previously known as Attunity connectors). Microsoft previously mentioned that it should provide faster performance than traditional OLE DB providers.

            Use the Oracle connection manager rather than OLE DB connection manager.

            To be honest, I am not sure if this component can make the data load faster since I didn't test it before

            Removing the destination and adding a dummy task

            The last thing to try is to remove the ODBC destination and add any dummy task. For example, use a row count component.

            Run the package; if the data is loaded faster, then loading data from Oracle is not decreasing the performance.

            3. SSIS configuration

            Now, let us start troubleshooting the SSIS package.

            Running in 64-bit mode

            First, try to execute the package in 64-bit mode. You can change this from the package configuration. Make sure that the Run64bitRuntime property is set to True.

            Data flow task buffer size/limits

            Using SSIS, data is loaded in memory while being transferred from source to destination. There are two properties in the data flow task that specifies how much data is transferred in memory buffers used by the SSIS pipelines.

            Based on the following Integration Services performance tuning white paper:

            DefaultMaxBufferRows – DefaultMaxBufferRows is a configurable setting of the SSIS Data Flow task that is automatically set at 10,000 records. SSIS multiplies the Estimated Row Size by the DefaultMaxBufferRows to get a rough sense of your dataset size per 10,000 records. You should not configure this setting without understanding how it relates to DefaultMaxBufferSize.

            DefaultMaxBufferSize – DefaultMaxBufferSize is another configurable setting of the SSIS Data Flow task. The DefaultMaxBufferSize is automatically set to 10 MB by default. As you configure this setting, keep in mind that its upper bound is constrained by an internal SSIS parameter called MaxBufferSize which is set to 100 MB and can not be changed.

            You should try to change those values and test your package performance each time you change them until the package performance increases.

            4. Destination Indexes/Triggers/Constraints

            You should make sure that the destination table does not have any constraints or triggers since they significantly decrease the data load performance; each batch inserted should be validated or preprocessed before storing it.

            Besides, the more you have indexes the lower is the data load performance.

            ODBC Destination custom properties

            ODBC destination has several custom properties that can affect the data load performance such as BatchSize (Rows per batch), TransactionSize (TransactionSize is only available in the advanced editor).

            How to seed users, roles when I have TWO DbContext, a) IdentityDbContext & b) AppDbContext
            Asked 2022-Jan-18 at 06:06

            normally I would put the code for seeding users in the OnModelCreating() Its not an issue with one DbContext.

            Recently it was recommended to separate identity's DbContext from the App's DbContext, which has added two DbContexts and some confusion.
            1. public UseManagementDbContext(DbContextOptions options) : base(options) // security/users separation
            2. public AppDbContext(DbContextOptions options) : base(options)

            But when you have two separate DbContexts, How do I seed the user / role data?

            1. IdentityDbContext -- this has all the context for seeding

            2. AppDbContext -- this does NOT have context, but my Migrations use this context.

            Can you please help how to seed the user and role data, and is part of the migrations or startup etc.

            ADF vs SSIS recommendation for data migration
            Asked 2021-Sep-28 at 13:44

            I hope this is ok to ask here. I have been looking through so many sites but still unable to come up with a decision. Here's the scenario. I have a legacy application that has it's data in Sql Server database(s). A new application has now been created that also will be storing data in a Sql Server database. I need to now migrate the data from the legacy to the new application. The legacy database(s) structures have been modified in the new application to follow best practices and make it more efficient (eg: use of PK, FK, indexes, lookups, better table structures etc). So there will be a lot of transformation (lookups, data cleaning, merging/splitting data etc) happening from source to destination. Initially we will be doing only 5 years worth of data, but at a later point we may need to move the rest of the data across.
            The company uses Azure for storage and there is no on-prem resources.
            Given this situation, what would be the best option for Data Migration? SSIS or ADF? What are the advantages of one over the other (other than the fact that ADF is Azure cloud based and MS are probably moving to ADF more in the future). We will also need Dev/Test/Prod environments if that matters.

            Answered 2021-Sep-28 at 11:33

            Considering the company doesn't have on-prem resources, I would be looking at implementing the data migration on Azure Data Factory. Below are few points to take into consideration:

            Pros:

            1. Integration between ADF and other Azure resources e.g. SQL Database is seamless and doesn't require connector setup, etc.
            2. You would take advantage of Microsoft's network to improve your data transfer, your data won't go over the network, everything is within MS data centers.
            3. More secure and reliable transfer, you could take advantage of ADF Managed Identity for authenticating to your source and destination.
            4. Since there will be a lot of changes, splits, etc, you can take advantage of ADF's ability to start from where the pipelines failed. On the other hand, in SSIS you'd need to start all over again.
            5. Better monitoring capabilities

            Cons:

            1. You'd need an infrastructure to develop, deploy, and run your SSIS packages, which will increase implementation time and maintenance overhead.
            2. You could run SSIS packages using ADF, but it requires a much bigger implementation to host your packages and run them. Also, it'd be more costly.
            3. If the plan is to use a VM, there is an additional overhead to set up the VM and SSIS. Also, the cost associated with spinning up a new VM and SQL Server.
            4. Not great monitoring and retry capabilities

            What wrong am I doing?

            You're not doing anything wrong. It's just that the Cosmos DB SDK used by this tool is very old (Microsoft.Azure.DocumentDB version 2.4.1) which targets an older version of the Cosmos DB REST API. Since you created your container using a newer version of the Cosmos DB REST API, you're getting this error.

            If your container is pretty basic (in the sense that it does not make use of anything special like auto scaling etc.), what you can do is create the container from the Data Migration Tool UI itself. That way you will not run into compatibility issues.
