weeks, which requires manual intervention, which is not annoying). Therefore, the ESB built based on RabbitMQ was comprehensively optimized some time ago ,, to ensure the stability and reliability of the ESB service, an automated ESB monitoring and O M system is initially established. This article introduces one of the technologies used in this system, SSIS is used to monitor the disk space of remote servers and send email alerts. The purpose is to

Zhang San Mathematics 83 Null Null Null C. Component 【Merge], Merge is 【Merge join] And [multicast only three] are merged after sorting. The first input is [sort _ Zhang sanli 4 left join]. Because there are multiple columns (5 rows and 6 columns), the data structure prevails. The second input is [sort _ zhangsan] (2 rows and 3 columns) Merge and convert It can be seen that the number of columns in [sort _ 3] is insufficient. Therefore, when merging with the tab

In SSIS, a field with Identity is often introduced. The Identity field cannot be inserted. There is a stupid way to achieve this. First set the Identity field of the target data table to No, and then set it back after the data is imported. Of course, this is troublesome and error-prone. In fact, it can be done through settings. Setting Method (here, the ole db method is used as an example ): 1) double-click ole db Destination. In the pop-up window, se

In the SSIS advanced conversion task-export column article, we mainly export the file columns in the database. Here we will discuss how to import files to the database, it is a pair of frequently used tasks with the export Column task. When we figure out what functions they implement, we will find that the original names are more appropriate. This type of conversion converts physical files in the system file path into table data in the database, and v

A Web service task is a newly added task in SSIs. It can connect to a WebService and execute a method in the service. After the method is executed, the result can be written back to a variable or file. This task is suitable for processing information in third-party applications. For example, you can use this task to execute WebService to obtain the updated product list of Amazon and write the information to the local server. Open HTTP Connection Mana

Script tasks allow you to use the Microsoft Visual Studio environment to create and execute scripts in the VB. NET language. ActiveX tasks allow script execution from SQL Server 2000. Compared with ActiveX tasks, script tasks have some advantages. As shown below. A complete set of smart design Environments Easily pass parameters to the script Easily in the scriptCodeSet breakpoint You can pre-compile the script in binary format. In the script task editing interface, 3-17 h

Data Flow tasks are a core task in SSIs. It is estimated that most ETL packages are inseparable from data flow tasks. So we also learned from data flow tasks. A Data Flow task consists of three types of data flow components: source, conversion, and target. Where: Source: it refers to a group of data storage bodies, including tables and views of relational databases, files (flat files, Excel files, XML files, etc.), and datasets in system memory. Conve

From http://microsoftdw.blogspot.com/, good blog for SSIs So sometimes you have data that does not come up right in Excel because either it's not formatted, or it's got mixed types. the end of it all is you just need it to come in as text and you can convert it later. my good friend, Robert Skoglund gave me this hint and I dug up some info on it .... Basically, add the option IMEX = 1 to the connectionstring for excel. This forces the columns to be tr

In the previous article, we used an example to introduce SSIS package development. next we will learn how to use the tabs in the package. such as the Connection Manager tab, control flow tab, data flow tab, and event processing tab. This article describes the functions and usage of the Connection Manager. The Connection Manager is used to connect to different types of data sources to extract and load data. Source data is required for development of an

combines two sorted data sets into one dataset. Insert the rows to the output based on the values of the key columns of the rows in each dataset. The merge conversion function is similar to the Union all clause in the T-SQL statement. Merging and conversion require that the input column have matched source data. In the SSIS designer, the merged and converted user interface automatically maps columns with metadata. You can then manually map other colu
