z/IRIS Client Started Task

Created:  | Updated: 

Create a z/IRIS client PROCLIB member

  1. Locate the ZIRIS file in the jcl folder of the zosclient_{VERSION}.zip and store it in a concatenated PROCLIB data set. The default member name is ZIRIS but can be changed to any valid member name as required.

  2. Change $APP_HOME in the proclib member to the zFS installation directory for z/IRIS:

    export APP_HOME=/usr/lpp/ziris/ziris114
  3. If mode=kafka in the ziris.comm.config file:

    1. Uncomment the following line and define the Kafka home directory to z/IRIS z/OS: 

      # export KAFKA_HOME=$KAFKA_HOME

    2. Change $KAFKA_HOME to the Kafka installation directory on Unix System Services:

      export KAFKA_HOME=/usr/lpp/kafka/kafka_2.13-3.4.0
  4. Change $JVAHOME to the JAVA_HOME directory in Unix System Services, where IBM JZOS or Semeru Runtime is installed.

    export JAVA_HOME=/usr/lpp/java/J11.0_64/
  5. Save the proclib member.

  6. Verify that the surrogate user ID is defined in RACF for this started tasked. See Install z/IRIS clients | Preparing-for-the-installation for details about RACF requirements.
