    Hmm, seems like your software install is either messed up or your environment variables are not setup correctly.

    Re: lsnrctl - Startup in AIX Installation

    Oracle executables (such as SVRMGR, oracle, etc.) on AIX are built with the assumption that the post-wait extension is running in the UNIX kernel. If the extention does not exist, the above errors will occur.
    On most UNIX platforms, Oracle uses semaphores to synchronize shadow processes and background processes. But with RS/6000 AIX, the post/wait drive is used instead to increase the performance. The most common solution is to re-install the kernel extension. The best way to do this is to apply patch 2896876 . This patch is designed to clean-up existing kernel extension, re-install them, and update /etc/inittab to automatically load the proper extension at boot time. Please review the patch installation output to determine if a reboot is required This may be required if rootpre.sh was run more than once. When rootpre.sh is run, it issues the command: ' /etc/loadext /etc/pw-syscall ' The second time this command is issued, the one that is currently running will be deactivated, thus giving the error above when database is brought up. Rebooting the machine will clean out the deactivated drive in kernel and rerun the system call.
    Also, you may want to do the following before rebooting:
    1. Login as "root"
    2. Change locations to the "etc" directory
    # cd /etc
    3. Verify that the "loadext" and "pw-syscall" files exist
    # ls -l loadext
    # ls -l pw-syscall*
    4. Query whether kernel extension is loaded or not:
    # ./loadext -q pw-syscall
    If a kernel extension is already loaded, check the version
    # ./loadext -r pw-syscall
    If the kernel extension version is older the the reqested version, unload the version before loading the new version
    # ./loadext -u pw-syscall
    5. Mannually load the kernel extensions
    # ./loadext -l pw-syscall
    6. Invoke lsnrctl to see if you still get the error
    Then,
    7) Run the rootpre.sh script. Insert the Oracle Server CD (CD #1 if
    8.1.7 or above) into the CD-ROM drive.
    8) As the user root, enter the following commands:
    # mount -rv cdrfs /dev/cd0 /cdrom
    # cd /cdrom
    # ./rootpre.sh
