Network

These environment variables are concerned with the operation of InfoSphere® DataStage® parallel jobs over a network.

APT_DEBUG_ENVIRONMENT
Set this environment variable to cause the conductor and each section leader to dump out their environment variable list.
APT_PM_ENV_NOCLOBBER
Set this environment variable to cause the environment to be dumped after the conductor's environment is instantiated.
APT_PM_ENV_DEBUG
Set this environment variable to cause the environment to be dumped before the conductor's environment is instantiated.
APT_IO_MAXIMUM_OUTSTANDING
Set the APT_IO_MAXIMUM_OUTSTANDING environment variable tp specify the amount of memory, in bytes, allocated to an InfoSphere DataStage job on every physical node for network communications.
APT_IOMGR_CONNECT_ATTEMPTS
Set the APT_IOMGR_CONNECT_ATTEMPTS environment variable to specify the number of attempts for a TCP connect in case of a connection failure.
APT_PLAYER_CONNECTION_PORT
Set this environment variable to specify the base port number to be used when binding the listener port for setting up TCP/IP connections between players.
APT_PM_CONDUCTOR_HOSTNAME
Set the APT_PM_CONDUCTOR_HOSTNAME environment variable to the network name of the processing node from which you invoke a job, if it is not included in the configuration file.
APT_PM_CONDUCTOR_TIMEOUT
Set this to control how long the section leader waits for a response from the conductor.
APT_PM_CONNECT_USING_NAME
Set this environment variable so that the data connection from a consuming partition to a producing partition is made using the hostname of the producer, instead of the IP address of the producer.
APT_PM_NO_TCPIP
Set the APT_PM_NO_TCPIP environment variable to turn off use of UNIX sockets to communicate between player processes at runtime.
APT_PM_NODE_TIMEOUT
Set the APT_PM_NODE_TIMEOUT environment variable to control the number of seconds that the conductor waits for a section leader to start up and load a score before deciding that something has failed.
APT_PM_PLAYER_TIMEOUT
Set this environment variable to specify the number of seconds that the proto section leader waits for player processes to respond before aborting.
APT_PM_SHOWRSH
Set the APT_PM_SHOWRSH environment variable to display a trace message for every call to RSH.
APT_PM_STARTUP_PORT
Use this environment variable to specify the port number from which the parallel engine will start looking for TCP/IP ports.
APT_RECVBUFSIZE
Set the APT_RECVBUFSIZE environment variable to specify the per-connection TCP/IP buffer space that is allocated.
APT_USE_IPV4
Set this environment variable to force network class to use only IPv4 protocols.
