Creating and deleting instances using the Command Central web user interface
By default, the working directory of an instance is APAMA_HOME/command-central/instances/ComponentType/instance_name. All the log files including stdout and stderr are located in the instance_name/logs folder. The environment variables ${APAMA_WORK} and ${APAMA_HOME} can be used inside extraArgs, iafConfigFile and log files, and this will be replaced with the location of those directories.
For correlator and IAF components, the environment variables PATH and LD_LIBRARY_PATH will be set as in a normal Apama command prompt. Any .dll and .so files placed in the ${APAMA_WORK}/lib directory will be automatically included in the PATH and LD_LIBRARY_PATH variables for correlator and IAF components.
