JCAPS6 Install Info

  • To Install JCAPS6 on AIX 5.3 we need to be at this APAR level for Java 1.5 64bit: APAR # IY98586 (http://www-933.ibm.com/eserver/support/fixes/fixcentral/pseriespkgoptions/apar?fixes=IY98586)
  • Sun has provided some recommended environment variables for running 5.1.3 domains on AIX:

    export AIXTHREAD_SCOPE=S
    export AIXTHREAD_MUTEX_DEBUG=OFF
    export AIXTHREAD_COND_DEBUG=OFF
    export AIXTHREAD_RWLOCK_DEBUG=OFF
    export SPINLOOPTIME=500

    These eliminate some of the overhead AIX imposes by default when managing
    threaded applications.
  • First check if there is sufficient space under the temp directory by giving
    df -k /var/tmp
    The output will look like this,
    $ df -k /var/tmp
    Filesystem kbytes used avail capacity Mounted on
    /dev/dsk/c1t0d0s0 62329116 11321890 50383935 19% /

    Other things that need to be set on the unix telnet window are:
    JAVA_HOME=<path to jdk1.5 or 1.6>
    PATH=JAVA_HOME/bin:$PATH
    IATEMPDIR=/var/tmp [If user does not have permission to /tmp ]

    CLASSPATH=JAVA_HOME/bin:$CLASSPATH
    For Solaris, HPUX : LD_LIBRARY_PATH =JAVA_HOME/jre
    For AIX : LIBPATH=JAVA_HOME/jre
