Note

If you are not able to start up the environment or if there are problems running sqlci or trafci, then verify that the all the processes are up and running.

  • swstatus should show at 6 java servers and 2 mysql processes. 
  • sqcheck should indicate all processes are running. 

If processes are not running as expected, please stop Trafodion by running sqstop, stop the Hadoop processes by running swstopall, then restart by running swstartall and sqstart. Sometimes then:

  1. stopstop to shut down Traodion. If some Trafodion processes do not terminate cleanly,
you can
  1. then run ckillall.
  2. swstopall to shut down the Hadoop ecosystem.
  3. swstartall to restart the Hadoop ecosystem.
  4. sqstart to restart Trafodion.

to quickly terminate all Trafodion processes. If problems persist please review logs:Hadoop, HBase, and Hive logs are located in

  • $MY_SQROOT/sql/local_hadoop/*/log: Hadoop, HBase, and Hive logs.
  SQL logs are located in
  • $MY_SQROOT/logs Trafodion logs.
