在ODI中使用Groovy设置数据源的订阅服务器

我们需要在许多映射上批量更改订户，但我发现很难构造正确的方法调用。我正在遍历映射列表，但不确定如何更改每个映射的订阅服务器。我的Groovy脚本中有以下代码结构：

//Created with ODI Studio

import groovy.swing.SwingBuilder

import java.awt.FlowLayout as FL
import javax.swing.DefaultComboBoxModel
import javax.swing.BoxLayout as BXL

import oracle.odi.domain.project.finder.IOdiProjectFinder;

//**********************************************************

// Careful, this is the project CODE, not the project name (all caps, no spaces)
myProject = "PROJECT"  // CODE of the ODI project where subscribers have to be replaced 
myFolder = "TEST FOLDER" // Folder where subscribers have to be replaced 
NewSubscriberName="TEST_SUBSCRIBER"  // Name of the new Subscriber that will replace the old one
MappingNamePattern="MAP_"  // Any part of the mapping name, if there is a pattern. Leave blank to process all mappings. 
// Example for patterns: "LOAD_" will process mapping LOAD_CUSTOMERS and PRELOAD_CUSTOMER but not LOADER_PRECURSOR

//--------------------------------------
// Build the list of available Folders

def getFoldersList(projectCode){
  folders = []
  foldersList = ff.findByProject(projectCode)

  for (folder in foldersList){
    folders.add(folder.getName())
    //println(folder.getName())
  }

  folders.sort()

  return folders
}

//-------------------------------------------------------------
// Main processing 
// First, retrieve the ODI studio connection to the repository
txnDef = new DefaultTransactionDefinition();
tm = odiInstance.getTransactionManager();
tme = odiInstance.getTransactionalEntityManager()
txnStatus = tm.getTransaction(txnDef);

// Create a few shortcuts for the finders
pf = (IOdiProjectFinder)odiInstance.getTransactionalEntityManager().getFinder(OdiProject.class);
ff = (IOdiFolderFinder)odiInstance.getTransactionalEntityManager().getFinder(OdiFolder.class);
mapf = (IMappingFinder) odiInstance.getTransactionalEntityManager().getFinder(Mapping.class); 

// Locate the folder in the project
OdiFolder folder = null;
folderColl = ff.findByName(myFolder, myProject)
if (folderColl.size() == 1)
  folder = folderColl.iterator().next();

if (folder == null) {
   println("*** Could not find folder named\""+myFolder+"\"")
   exit
}

//--------------------------------------
// Retrieve all mappings in that folder
def OdiMappingsList = mapf.findByProject(myProject, folder.getFolderId())
println("*** Processing mappings for Project \""+myProject+"\", Folder \"" + myFolder+"\"")

//--------------------------------------
// For each mapping, do the folowing:
// - print mapping name
// - check if mapping name matched search string. If not, print 'no action' and get to the next mapping
// - if we have a name match, replace Subscriber with the new value.

for (map in OdiMappingsList){
    println("*******\nMapping: " + map.getName())
    bSubscriberChanged=false        
    // Make sure that the mapping matches the names we are looking for 
    if (map.getName().contains(MappingNamePattern)){
        // Set the subscriber
        sources = map.getSources()
        for (sourceDS in sources) {
           --- I NEED TO SET THE SUBSCRIBER HERE ---
           bSubscriberChanged=true
        }
    } else {// No match on mapping name
        println ("Skipped mapping: name does not contain \"" + MappingNamePattern +"\"")
    }
    if (bSubscriberChanged){
        // Persist the changes in the cache
        tme.persist(map);
    }
}//Mapping

// Commit the changes in the repository
tm.commit(txnStatus);

非常感谢您的帮助。

您可以使用从IMAPComponentTowner（通过映射实现）检索映射的源组件列表。 这些源组件应为具有设置JournalizedFiler方法的类型

可能是这样的（还不能测试）：

请注意，此代码仅在组件设置为日记时更改过滤器

---

如果您当前的日志筛选器比这更复杂（例如，包含日期筛选器），则需要使用getJournalizedFilter（）并解析结果，以仅替换订户名称，而不是覆盖整个筛选器。

如果没有一些代码，我想社区将无法帮助您，试着编辑这个问题，这样你就可以得到一些答案了。我会那样做的。我只是在寻找一组处理设置订户值的类/方法。这太棒了。它解决了我的问题，尽管我确实需要使用isDatastoreJournalized而不是isJournalized。出于某种原因，iJournalized在我所有的消息来源上都返回了false。再次感谢！哦，这很奇怪，但是谢谢你的反馈。很高兴这有帮助。如果答案完全解决了你的问题，不要忘记接受它；）。

srcComps = map.getSources()
srcComps.each() { srcComp ->
    if (srcComp.isJournalized()) {
        srcComp.setJournalizedFilter("JRN_SUBSCRIBER = '"+NewSubscriberName+"'")
    }
}
