Network environment variables in DataStage

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

APT_IO_MAXIMUM_OUTSTANDING environment variable in DataStage
Set the APT_IO_MAXIMUM_OUTSTANDING environment variable tp specify the amount of memory, in bytes, allocated to an DataStage job on every physical node for network communications.
APT_IOMGR_CONNECT_ATTEMPTS environment variable in DataStage
Set the APT_IOMGR_CONNECT_ATTEMPTS environment variable to specify the number of attempts for a TCP connect during a connection failure.
APT_PLAYER_CONNECTION_PORT environment variable in DataStage
Set this environment variable to specify the base port number to use when binding the listener port for setting up TCP/IP connections between players.
APT_PM_CONDUCTOR_HOSTNAME environment variable in DataStage
Set the APT_PM_CONDUCTOR_HOSTNAME environment variable to the network name of the processing node from which you start a job, if it is not included in the configuration file.
APT_PM_CONDUCTOR_TIMEOUT environment variable in DataStage
Set this environment variable to control how long the section leader waits for a response from the conductor.
APT_PM_NO_TCPIP environment variable in DataStage
Set the APT_PM_NO_TCPIP environment variable to turn off use of UNIX sockets to communicate between player processes at run time.
APT_PM_NODE_TIMEOUT environment variable in DataStage
Set the APT_PM_NODE_TIMEOUT environment variable to control the number of seconds that the conductor waits for a section leader to start and load a score before deciding that something has failed.
APT_PM_PLAYER_TIMEOUT environment variable in DataStage
Set this environment variable to specify the number of seconds that the proto section leader waits for player processes to respond before stopping.
APT_PM_SHOWRSH environment variable in DataStage
Set the APT_PM_SHOWRSH environment variable to display a trace message for every call to rsh.
APT_PM_STARTUP_PORT environment variable in DataStage
Use this environment variable to specify the port number from which the parallel engine starts looking for TCP/IP ports.
APT_RECVBUFSIZE environment variable in DataStage
Set the APT_RECVBUFSIZE environment variable to specify the per-connection TCP/IP buffer space that is allocated.
APT_USE_IPV4 environment variable in DataStage
Set this environment variable to force network class to use only IPv4 protocols.
