Error description

• As currently configured, CICS Interdependency Analyzer provides
  numerous results to a Show Connections query. It would be
  helpful if there was a way to whittle down these results to
  easily get the desired data. This could be completed via:
  1.) Stop the query after 'n' number of connections,  showing
  the user the number of connections displayed.
  2.) Have the number of connections be a configurable option
  with a default that could be updated.
  3.) Get Next capability that would allow you to access the next
  logical connection.
  4.) Specify a range of connections.  For example, if there are
  100,000 connections, allow the capability for the customer to
  see numbers 9,900 - 15,000.
  5.) Povide information on the actual total of the records.  For
  example, if a screen displays the first 1000 records, and there
  are actuall 4000 records, we would indicate the screen is
  displaying 1-1000 out of 40,000 records.

Local fix

Problem summary

• The CICS Interdependency Analyzer Plug-in Resource Connections
  View loads all the resources related to a current Resource
  Connections graph, in memory. This is done even though most of
  the resource types are hidden by default. The user can then
  select some additional resource types in the Resource Filter
  pane, which will immediately display them on the graph (because
  these resources were already loaded in memory but hidden from
  view).
  When the data base contained a very large number of resources
  then loading all resources in advance in this way could cause
  the workbench to run out of memory and crash.
  

Problem conclusion

• The fix allows the user to make a step by step Resource
  discovery, when initially only those resources that are
  essential for building the connections graph are loaded (These
  are Programs and Transactions).
  After that, the user can select additional resource types using
  the Resource filter pane, and only load them, without loading
  the whole graph at a time.
  The plug-in will display a warning message, when too many
  resources have been loaded, preventing the workbench from
  crashing.
  The Resource Connections View now always shows the context of
  the current resources graph (The Region/Platform and Application
  which contained the initial Program/Transaction for the Resource
  Connections analysis). Prior to this fix, this context was
  implied, but the scoping Region/Platform and Application weren't
  displayed, making difficult for the user to understand how the
  resource connections graph is restricted. As in previous
  version, selecting All Regions, All Platforms, All Applications
  resource filters would expand the search context to all
  corresponding objects, showing multiple graphs grouped in boxes.
  The fix will be made available in version 5.2.0.3 of the CICS
  Explorer Interdependency Analyzer plug-in.
