Installation of Rational License Server 8.1.2 on AIX 5.3 TL5 results in "Symbol resolution" error

Technote (troubleshooting)


Attempts to install IBM Rational License Server 8.1.2 on AIX 5.3 TL5 result in the error "Cannot load program ibmratl".


The full error message is as follows:

exec(): 0509-036 Cannot load program ibmratl because of the following errors:

        0509-130 Symbol resolution failed for ibmratl because:

        0509-136 Symbol __pthread (number 175) is not exported from
                         dependent module /usr/lib/libpthread.a(shr_xpg5.o).

        0509-192 Examine .loader section symbols with the
                          'dump -Tv' command.


Rational license server 8.1.2 for AIX is built based on a machine with AIX 5.3 TL8 or later where the symbol __pthread is introduced, not in an earlier version.

Diagnosing the problem

You can use the following commands to check AIX machine where Rational License Server will be installed.

  • Find AIX version and TL level
    oslevel -r
  • Display the latest installed level of the fileset
    lslpp -l bos.rte.libpthreads
  • Dump the symbol table entries for the loader section
    dump -Tv libpthreads.a | grep __pthread

For example,

$ oslevel -r


$ lslpp -l bos.rte.libpthreads

   Fileset          Level              State               Description
