Instructions for installing IBM Connect:Direct for UNIX Maintenance.

Please note the following before beginning this procedure:

     Note 1:  The cdinstall script referenced below should be run by the userid 
              that owns the C:D UNIX installation directory.

     Note 2:  You will need root privileges to complete this procedure.

     Note 3:  The maintenance files are full installation files and can be used
              for a new installation.  To do so, follow steps 2 and 3 below, and
              then refer to the "Installing Connect:Direct for UNIX" chapter of
              the "Connect:Direct for UNIX Getting Started Guide" for further
              installation instructions:

     Note 4:  The cdinstall script incorporates backup/restore functionality. 
              If you select the UPGRADE option when cdinstall detects an 
              existing installation, you will be given a prompt to perform a 
              BACKUP of the existing installation.  We recommend choosing this 
              option.  If the upgrade fails for any reason, the cdinstall script 
              can be invoked and will detect the existence of the backup file 
              and give you the option to RESTORE the previous installation.

1. Shutdown Connect:Direct for UNIX.  This is important to assure all 
   replacement modules are installed correctly.

2. The maintenance installation files will need to be extracted.

     a) Create a temporary directory to hold the installation files,
        /CDUinstallationFiles, for example.
     b) Copy the CDU maintenance tar file into this directory and cd into it.
     c) Extract installation files from the tar file: 
        tar xvf 4.3.0.1-IBMSterlingConnectDirectforUNIX-AIX-pSeries-iFix000.tar
     d) The temporary directory should now contain the installation scripts,
        cdinstall and cdinstall_a, and the installation cpio archive file,
        cdunix.

3. To run the interactive upgrade or install procedure, execute the cdinstall 
   script:

      cdinstall

   This procedure will:

      a) Ask for your C:D UNIX installation directory with a prompt similar to 
         the following:

		Enter the FULL path of the Connect:Direct for UNIX 4.3.0.1 installation directory.
		You can use $HOME to shorten the name:[$HOME/cdunix]

         Respond with your fully qualified C:D UNIX installation directory, for 
         example:

            	/opt/applications/cdunix

         You will be given the option to create a backup of the existing 
         Connect:Direct installation during the next prompts.

      b) When the procedure asks for the location of the maintenance 
         installation file with a prompt similar to the following:

		Specify the fully qualified name of the Connect:Direct for UNIX installation
		file (file name prefixed with the absolute path, e.g., /localhome/cdadmin/cdunix):

         Respond with the fully qualified directory and filename of the 
         maintenance installation file, for example:

            	/CDUinstallationFiles/cdunix

         The procedure will then update the Connect:Direct installation, 
         including detected options, like C:D File Agent, or proceed with the 
		 installation option selected if the upgrade option was not selected.

   When the procedure requests root privilege, then:

      a) If you know the root password, or have a system administrator standing 
         by who knows the root password, then answer 'yes' when the cdinstall 
         script prompts for actions that require the root password.

      b) If you don't have access to the root password, but can use 'sudu' or 
         some other utility consistent with your companies security policies to 
         acquire root privileges, then answer 'no' when the cdinstall script 
         prompts for actions that require the root password, and after the 
         cdinstall script is finished:

         1) acquire root privilege with sudo or another method that is 
            consistent with your company's security policies

         2) execute the following script:

               {the C:D UNIX installation directory}/etc/cdcust

            and select the option to "Set owner and permissions of C:D 
            executables" 


After installing maintenance, it may be necessary to recompile/relink API 
programs and user exits.  Please refer to the fixlist to see what has changed 
since you last applied maintenance, and whether a recompile/relink is 
recommended.

Please contact IBM Customer Support if you have any questions or problems 
installing the maintenance.
