. On the off chance that you Want To Send Some Data From Access Database To SQL Server Database. What Are the Different Components Of SSIS that you Will Use?

Ans: In the information stream, we will utilize one OLE DB source, information change, and one OLE DB goal or SQL server goal. OLE DB source is an information source helps peruse information from Oracle, SQL Server, and Access databases. Information Conversion change would be expected to expel datatype anomaly since there is a contrast in datatype between the two databases (Access and SQL Server) referenced. On the off chance that our database server is put away on and the bundle is run from the same machine, we can utilize the SQL Server goal else we have to utilize the OLE DB goal. The SQL Server goal is the goal that improves the SQL Server.

. What do you mean by Data conversion Transformation?

. How can you stop a package from running forever?

Ans: It depends. On the off chance that you are running the bundle in the SQL Agent, you can slaughter the procedure utilizing T-SQL. Be that as it may, if the bundle is running in the SSIS inventory, you can stop it utilizing Active Operations window or the stop activity stored technique.

. What is the purpose of using the Ignore Failure option in SSIS?

Ans: By using the Ignore Failure option, the error will be disregarded and the information line will be coordinated to proceed with the following change. Suppose you have some JUNK information (wrong kind of information or JUNK information) spilling out of source, at that point utilizing this choice in SSIS we can REDIRECT the garbage information records to another change as opposed to FAILING the bundle. This assists with moving just legitimate information to goal and JUNK can be caught into a different file package.

. What is the multicast Transformation in SSIS?

Ans: Multicast Transformation means distributing its inputs to multiple outputs. Multicast Transformation is like conditional split transformation in which both will send data to multiple locations. With this transformation, we can send a path to numerous destinations. There is a slight difference between the two in multicast transformation: every row directs every output, and in conditional split, a row directs a single output.

. What are Process Bytes in SSIS?

Ans: Process bytes are also called private bytes (DTEXEC.exe); these represent the total amount of memory utilities by the integration service. Other Processes can not use process memory.

. How many lookup cache modes are present in SSIS?

Ans: In SSIS lookup transformation, there is a setting called Cache Mode that determines how the data is cached during runtime. There are three types of lookup cache modes that are a part of lookup transformation they are : 

In SSIS lookup transformation this is the default cache mode. Before the data-flow task is executed, this mode queries the data during the pre-execute phase. From the table, the entire data is copied and stored into the lookup cache in SSIS.

In this mode, the lookup values are cached, when a new row is added, the lookup transform scans the cache for the matching value, if any match is found with the database, then the value is cached if not it queries the database. If the lookup cache is complete, data will be deleted automatically and free up space.

The name explains everything. In this cache, the lookup transform will not maintain a lookup cache unless two successive sources are matched and Database queries run to compare data from time to time.

. What is File system deployment?

Ans: File system deployment means a package is deployed into a file system, i.e. to a specific folder and drive. With SQL agent job you can schedule when the package needs to run.

Ans: Alternatives for dynamic configuration in SSIS are:

XML file

Database per set with variables

Custom variables

. Explain Copy column Transformation?

Ans: Copy column transformation creates duplicate columns in SSIC, and it copies input columns and duplicates them in a new name. By using copy column transformation, we can make multiple copies, and multiple transformations can be applied to copies. With one copy, we perform one operation.

. Is it possible to log SSIS execution?

Ans: With log providers, Logging is implemented in SQL Server Integration Services. The log helps you audit, capture runtime information, and troubleshoot. SISS has different data sources, and Logging supports multiple formats like Windows Log, XML files and Logging information in text files.

. What will you do if a package runs fine in BIDS but fails while running from the SQL agent job?

Ans: To resolve the issue, we can use the following methods. Choose the appropriate method according to the reason that package has failed.

• Method 1: create a SQL Server Agent proxy account using SQL Server. Check credentials of proxy account and SQL Server Agent proxy account. This method has limitations and might fail even if the job step uses the exact proxy account.
• Method 2: SSIS package protection level property must be changed to server storage. With this setting, the package is stored in the SQL server database.
• Method 3: SSIS package protection level property must be changed to Encrypt. Apply password for encryption, include password, and modify the SQL server agent job step command line.
• Method 4: create a package template for long-term resolution. Use different level protection that differs from the default setting and create a package template.
