PK40567: INSTALL_IHS COMMAND MAY NOT WORK FOR SYMBOLIC LINKS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• install_ihs command  may not work with symbolic Symlinks.
  customers might have symlinks in the path to the SMP/E read-only
  APPLY directory.  the first component of their path is a symlink
  that apparently changes among members of a sysplex. By default,
  the z/OS shell uses the link target as the result of a built-in
  cd or pwd.
  

Local fix

• One suggestion fis to provide the product path to the
  install_ihs shell.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IBM HTTP Server for WebSphere   *
  *   (powered by Apache) on z/OS                                *
  ****************************************************************
  * PROBLEM DESCRIPTION: IHS install is using the physical path  *
  *                      when creating symlinks from the         *
  *                      installation directory to the product   *
  *                      directory. If symbolic links are used   *
  *                      anywhere within the IHS product         *
  *                      directory, when the symlink is changed  *
  *                      to point to a different mount point for *
  *                      the product directory the installed     *
  *                      product does not reflect the change.    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Path references within the IHS product directory are set at
  install time by the install_ihs script. The script creates
  symlinks for some files from the install directory to the
  product directory. If the product directory itself has
  symlinks then the symlink from the install directory should
  have the logical path, but instead it has the physical path
  to the product directory.
  

Problem conclusion

• If using a symlink in the product directory path, the symbolic
  link will be used by the product installation, not the physical
  path. Users can then change the mount point of where the product
  directory is, along with the symbolic link from the installation
  directory to it. The path in the install directory will be
  updated when the symlink is changed, there will no longer be
  references to the physical mount point.
  
  The symlink will only be obtained if the product directory is
  the default path of: /usr/lpp/zWebSphere_OM/V6R1/HTTP/Server.
  If not using the default product directory it is recommended to
  invoke install_ihs using it absolute path.
