Action Plan

Perform the below actions

  1. Locate the run extension at application level log file
  2. Identify if the extensions registered at the beginning of the log are CAST official or custom extensions. You can verify this at CAST Extend  by searching for the extension and looking at the extension details Last Published: Date By XXXX:
    1. If XXX is CAST Product then the extension is supported
    2. If XXX is CAST User Community or  CAST Labs then the extension is not supported. If you discover in the next steps that the issue is caused by an unsupported extension, then contact directly the extension author by using the 'Contact Publishers' form found on the extension page.
  3. Identify the step where the issue occurs. The issue can happen before, during, or after running an analysis of a specific extension. Locate the relevant log messages that describe the beginning and end of the analysis for that particular extension.

    • If no ‘Running plugin’ information message is visible in the log, then an issue occurs before running analysis for a specific extension
    • If the issue occurs after a ‘Running plugin’ message and before a ’Done Running plugin’ message, then it occurs during  the analysis of a specific extension
    • If the issue occurs after a ‘Done Running plugin’ and there is no new ‘Running plugin’ message, then it occurs after the analysis of a specific extension
  4. Identify the kind of issue as per CAST Management Studio - Information - Type of issues
  5. According to the identified step and type of issue, identified in previous steps:
    1. If the issue occurs before the analysis of a specific extension
      1. If it is a performance issue:
        1. If it is a performance issue during updating CSV calculation:
           2016-12-16 09:53:32,142 INFO Updating cast system views ...
          1. If some unsupported extensions are used, then they may use update CSV steps. This is outside the scope of support and you should contact directly the extension author.
          2. If only supported extensions are used, CSV calculation is not used by the supported extensions and you can remove it by doing the following:
            1. Create a copy of <INSTALL_FOLDER>\Third-Party\Python34\Lib\site-packages\cast\application\internal\run_plugins.py and rename it to run_plugins.original
            2. n <INSTALL_FOLDER>\Third-Party\Python34\Lib\site-packages\cast\application\internal\run_plugins.py in a text editor like Notepad++ and replace following lines:

              logging.info("Updating cast system views ...")
              kb.update_cast_system_views()
              logging.info("Updating cast system views Done")

              with:

              logging.info("Updating cast system views function has been suspended...")
            3. Rerun analysis

    2. If the issue occurs during the analysis of a specific extension
      1. If it is a performance issue:
        1. Upgrade to the latest functional release version of the extension and rerun analysis.
        2. Check troubleshooting guides for specific extensions
    3. if the issue occurs after the analysis of a specific extension, Open the log "ApplicationExtensions-[DateTime].castlog" and check which extension is stuck.
    4. If there are warnings in the ApplicationExtensions-[DateTime].castlog log as below:

        File "C:\Program Files\CAST\8.3\ThirdParty\Python34\lib\site-packages\sqlalchemy\pool.py", line 948, in _do_get
          return self._pool.get(wait, self._timeout)
        File "C:\Program Files\CAST\8.3\ThirdParty\Python34\lib\site-packages\sqlalchemy\util\queue.py", line 145, in get
          raise Empty
      sqlalchemy.util.queue.Empty
      
      During handling of the above exception, another exception occurred:
      
      Traceback (most recent call last):
        File "C:\Program Files\CAST\8.3\ThirdParty\Python34\lib\site-packages\sqlalchemy\engine\strategies.py", line 90, in connect
          return dialect.connect(*cargs, **cparams)
        File "C:\Program Files\CAST\8.3\ThirdParty\Python34\lib\site-packages\sqlalchemy\engine\default.py", line 377, in connect
          return self.dbapi.connect(*cargs, **cparams)

        File "C:\Program Files\CAST\8.3\ThirdParty\Python34\lib\site-packages\pg8000\core.py", line 1263, in __init__
          raise self.error
      pg8000.ProgrammingError: (b'FATAL', b'53300', b'sorry, too many clients already')
