APAR status
Closed as program error.
Error description
Environment: TEPS on AIX, but possibly other environments as well. This is not a regression, since the failing code has been in the product for a long time. Problem Description: If the TEPS is defined with only MQ Configurator agents, then there are no visible nodes except the Enterprise node. If the offline entry is done from the managed system status table, the TEPS will abend during the destructor of an intermediate graph which has a null pointer as part of the graph object. This should not abend.
Local fix
A work around to prevent the abend is to have an MQ agent that comes online. This will circumvent the code in error and the TEPS will not abend.
Problem summary
When offline nodes are cleared and there are no nodes left on the Physical Navigator tree except the Enterprise node, the TEPS process abends with: Segmentation fault in destroy__22VISResourceImplFactoryFP15VISResourceImpl
Problem conclusion
When an offline node is cleared, the TEPS navigator is updated to remove the node. When there are no viewable nodes left, a graph with no nodes is returned. When the destructor for this graph is called it tries to free the associated nodes. Since no nodes exist, the process abends with: Segmentation fault in destroy__22VISResourceImplFactoryFP15VISResourceImpl The code was modified such that the method that returns a graph with no nodes, returns a null graph instead. This prevents the destructor from attempting to free non-existent nodes. The fix for this APAR is contained in the following maintenance packages: | interim fix | 6.2.0.2-TIV-ITM-IF0001
