Environment

  • Release: UIM 20.3
  • Component : UIM - URL_RESPONSE
  • ppm: v20.10hf3
  • url_response: v4.46 (suggested testing with url_response probe v4.50 GA)

Cause

- corrupt url_response.cfg
- After removing the probe previously, the ppm error occurred and opening the url_response probe failed due to the folder not being completely removed from the file system on the first try.

Resolution

First thing to try is upgrading to v4.50.
http://support.nimsoft.com/Files/Archive/00058/url_response-4.50.zip

As there were 6 significant fixes since v4.46.

Second thing you can try is based on this portion of the error copied into the case since it appears that the url_response probe.cfg could have become corrupted.

Aug 02 13:32:33:872 [attach_socket, ppm] (url_response) Instance data population for adapter '/UAxx/xxxxxxxx/xxxxxxxx/url_response' failed 
Aug 02 13:32:33:872 [attach_socket, ppm] java.lang.NullPointerException 
 at com.nimsoft.ppm.adapter.TempCommonAdapter.createConfigObject(TempCommonAdapter.java:1414) 

We have seen at least a few cases of the error PPM-011 where this same error was generated due to url_response.cfg corruption.

1. Save off your current url_response folder or url_response.cfg for safe keeping
2. In IM, Rt-click and delete the url_response probe
3. Then delete the url_response folder from the file system
4. Then redeploy the url_response probe

Next, check if you are able to open the probe via the AC while the url_response probe has only its default configuration.

That is a good test to try and detect any .cfg file corruption for probes in general.

A good, healthy startup of the ppm probe will look similar to this in the ppm.log when set to loglevel 5.

Then when the url_response probe configuration is successfully opened in the Admin Console it should show:
Aug 02 20:43:28:861 [attach_socket, ppm] (AdapterFetcher) Probe [url_response] & Version [4.50] are found inside Robot [/xxxxxxxx_domain/xxxxxxxx_hub/xxxxxxxx] archive... 

Deleting and reinstalling the probe was successful and the probe opened in Admin Console (AC).

Note that if the url_response.cfg is restored and the problem returns, check the .cfg in Notepad++ for any sign of corruption (select 'Show All Characters' option in Notepad++).
