AIX 5.3 Support

Packages validated

We have validated a subset of the VDT on AIX 5.3:

• Globus
  • Globus-Base-Essentials (grid-proxy-init, globus-url-copy, etc.)
  • Globus-Base-Data-Server (GridFTP service)
  • GRAM + Fork job manager
  • Condor job manager
• Apache - requires some configuration after installing

Notable packages that are unsupported

• Globus-WS
• VOMS
• GUMS

System requirements

We installed the following RPMs on our test system when validating the software listed above:

• RPMs (can be found at ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/).
  • wget (wget-1.9.1-1.aix5.1.ppc.rpm) - Possibly necessary for Pacman. Prereq for vdt-update-certs
  • python (python-2.3.4-2.aix5.1.ppc.rpm) - Pacman prereq
    • readline (readline-4.3-2.aix5.1.ppc.rpm) - Python prereq
    • db (db-3.3.11-4.aix5.1.ppc.rpm) - Python prereq
    • gdbm (gdbm-1.8.3-2.aix5.1.ppc.rpm) - Python prereq
  • GNU tar (tar-1.14-2.aix5.1.ppc.rpm) - Pacman prereq
  • Openssl 0.9.7l (openssl-0.9.7l-2.aix5.1.ppc.rpm) - Prereq
  • Pseudo-random number generator (prngd-0.9.29-1.aix5.1.ppc.rpm) - OpenSSL prereq
  • bash (bash-3.0-1.aix5.1.ppc.rpm) - Probably not necessary - but convenient
  • less (less-382-1.aix5.1.ppc.rpm) - Not necessary, but convenient
• Installed Java 5 SDK. This must be installed at /usr/java5/. This is not necessary for Globus, GridFTP.

Installing Apache

Apache does not link properly, and we currently do not know how to fix this. If you know how to fix this, please let us know! In the meantime, here's a hack to make Apache work:

1. Install the Apache package

   pacman -get http://vdt.cs.wisc.edu/vdt_1101_cache:Apache

2. Move some library files so that Apache can find them.

   mkdir -p /home/condor/execute/dir_25078/userdir/apache/lib
   cp -r $VDT_LOCATION/apache/lib/* /home/condor/execute/dir_25078/userdir/apache/lib
   

3. Fix the LIBPATH to prevent other programs from linking against Apache's libexpat

   # In $VDT_LOCATION/post-setup.sh, add the following two lines
   LIBPATH =`perl -e '($tmp = $ENV{LIBPATH}) =~ s|$ENV{VDT_LOCATION}/apache/lib:?||; print $tmp'`
   export LIBPATH
   
   # Ensure that $VDT_LOCATION/apache/lib is not in LIBPATH after sourcing setup.sh
