To be able to use the C for AIX Compiler, a server-side license and configuration must done as well as a client-side installation. Here are the steps to achieve this goal.

1. madre is the hostname of the AIX server on which to install the C for AIX Compiler (license and tools)

First, check the necessary AIX filesets (and install them accordingly):

# lslpp -l | egrep "vac|bos.rte |bos.adt.libm" | sort -u
  bos.adt.libm              5.3.0.10  COMMITTED  Base Application Development
  bos.rte                   5.3.0.10  COMMITTED  Base Operating System Runtime
  vac.C                      6.0.0.0  COMMITTED  C for AIX Compiler
  vac.C.readme.ibm           6.0.0.0  COMMITTED  C for AIX iFOR/LS Information
  vac.lic                    6.0.0.0  COMMITTED  C for AIX Licence Files

For simplicity purpose, the same packages will be installed on each of the server and the client for the C for AIX Compiler.

Note #1: the bos.* filesets can be found in the lpp source lpp_source530.

Note #2: the vac.* filesets can be found in the lpp source C_for_AIX_60.

Configuration of the license server: Concurrent Network License Server

Based on information found in the file /usr/vac/README.password:

Check for the necessary License Use Runtime filesets:

# lslpp -l | egrep "ifor" | sort -u
  bos.rte.ifor_ls            5.3.0.0  COMMITTED  iFOR/LS Libraries
  ifor_ls.base.cli          5.3.0.10  COMMITTED  License Use Management Runtime

To configure LUM, perform the following steps (based on the content of /usr/vac/cforaix_c.lic):

# cd /usr/opt/ifor/ls/os/aix/bin
# ./i4config
/*
 * Answer the LUM configuration questions as appropriate (configure a Concurrent Network license server):
 * a) Select 4 "Central Registry (and/or Network and/or Nodelock) License Server" on the first panel
 * b) Answer y to "Do you want this system be a Network License Server too?"
 * c) Answer n to "Do you want this system be a Nodelock License Server too?"
 * d) Answer n to "Do you want to disable remote administration of this Network License"
 * e) Select 2 "Direct Binding only"
 * f) Answer n to "Do you want to change the Network License Server ip port number?"

 *    working as Network License Client)?"
 * k) Select 3 "Create a new list" to the direct binding list menu
 * l) Enter the hostname, without the domain, of the system you are configuring LUM when prompted for the "Server network
 *    name(s)", for example: madre
 * m) Answer n to "Do you want to change the default ip port number?"
 * n) Select 1 "preserve the current list" to the direct binding list menu
 * o) Answer y to "Do you want the License Server(s) automatically start on this system at boot time?"
 * p) Answer y to continue the configuration setup and write the updates to the i4ls.ini file
 * q) Answer y to "Do you want the License Server(s) start now?"

The Concurrent Network license certificate is contained in the file /usr/vac/cforaix_c.lic. To enroll a license certificate:

# cd /usr/opt/ifor/ls/os/aix/bin
# ./i4blt -a \
          -v "'IBM Software Solutions Toronto' 5da54a553b4c.02.09.15.31.05.00.00.00 p9gb3ycs6ydpw" \
          -p "'C for AIX' '6.0.c' bcmefhz6zkdmdaaxe524si3kbgb2zwxsaqskixs222 " \
          -T 1 \

After enrolling a concurrent-network certificate, the licenses must be distributed to one or more LUM license servers (only for Concurrent-Network Certificate Enrollment):

# ./i4blt -E \
          -n madre \
          -v "'IBM Software Solutions Toronto'" \
          -p "'C for AIX' '6.0.c'" \
          -A 1 \
