Error description
Discoveries performed through ITM utilise KT1 which issues many SOAP requests to query the Hub's Node Status table. These requests involve an entire scan of Node Status table which can each take a number of seconds to complete if the Node Status table is large. Due to the high volume of these requests, TADDM discovery requests are prolonged and SOAP threads are monopolised preventing concurrent tacmds from running.
Local fix
N/A
Problem summary
Throughout the course of a TADDM discovery via TEPS, KT1 sends many requests to the Hub to obtain the Node Status of agents. These requests compete with the actual discovery requests that are sent to each agent. This contention causes the discovery requests to wait prolonging the overall time of the discovery. The contention also means that concurrent tacmd requests will wait until a SOAP thread becomes available. TADDM Discoveries through ITM take too long to complete. Also, during a discovery, tacmd may hang and Hub CPU may increase.
Problem conclusion
KT1 now supports the caching of Node Status records which eliminates > 95% of the requests that are sent to the Hub during a discovery. Caching is enabled when a new environment variable, KT1_NODE_STATUS_CACHE_TTL, is defined with a value > 0 and < 86400 seconds. A higher TTL value will reduce the number of requests sent to the Hub. A value of 900 seconds is recommended. (see Install Actions below) The fix for this APAR is contained in the following maintenance packages: | service pack | 6.3.0.7-TIV-ITM-SP0001 Install Actions: The environment variable, KT1_NODE_STATUS_CACHE_TTL=<# of seconds> should be added to the TEPS configuration file: $CANDLEHOME/config/cq.ini (Unix/Linux) %CANDLE_HOME%\CNPS\KFWENV (Windows)
