Issue/Introduction

Issue: 

What to do if you get the following error when trying to add a “Data Aggregator” data source to CAPC:
“Adding Data Source failed
Data source is already registered to another Performance Center”

This happened  when I uninstalled and reinstalled CAPC without removing the data sources first.

Environment:  

IM 2.5

Linux 6

 

Workaround:

The following details how to update the data repository using the Google Rest Client.

• Download the Google Rest Client
http://code.google.com/p/rest-client/downloads/list
I used the 3.0 client.

Once the client is loaded, Select Tools/Options/Etc. and make sure all three boxes are selected.

In the URL Field enter the following URL:
http://<dataaggretor name or IP>:8581/rest/dataaggregator/
 

<Please see attached file for image>

Under Method tab, select Get, and at the bottom, select Body and click the   to run the Get.  You should see output in the body such as this:
To continue, you will need the value that is in the <ID>#</ID> field.  In this case it is “4”.

Go to the Method tab and change to “Post”.

Next, click the “Body” tab near the top of the client.

Select “String Body” from the list.

Change back to the “Body” tab.

Copy and paste the following XML lines into the body section (Ctrl-C and Ctrl-V work):
<DataAggregatorInfo version="1.0.0">
  <NpcSyncIncrementTime>0</NpcSyncIncrementTime>
  <NpcSyncBaseTime>0</NpcSyncBaseTime>
  <NpcID></NpcID>
  <NpcPushSyncIncrementTime>0</NpcPushSyncIncrementTime>
  <NpcPushSyncBaseTime>0</NpcPushSyncBaseTime>
  <NpcHostName>""</NpcHostName>
  <NpcConnectionUID>""</NpcConnectionUID>
</DataAggregatorInfo>

Change the URL to include the “ID #” that was located earlier.  In this case it was “4”. Your URL should now look something like this:
http://<dataaggretor name or IP>:8581/rest/dataaggregator/4
Change back to the “Method” tab.
Change the Method to “Put”.
Click the   button.

This will update the repository and remove any information about the previous Data Collector.  You can go back to:
http://<dataaggretor name or IP>:8581/rest/dataaggregator
and run a Get method and your XML should be blank now. 
You can now add your data collector the CAPC again.
