<ul class="list">
<li class="item"> Review the original installation instructions to refresh the various
considerations involved.
<li class="item"> Some <span class="high italic">insurance</span> on the directory tree is recommended in case
the update should fail or otherwise be unusable or problematic (of course, this
is good advice whenever about to make major changes to anything!) This may be
in the format of a regular site backup, special pre-update backup, or special
pre-update ZIP archive of the directory tree. The latter two could be
accomplished using commands similar to the following:
<div class="blockof code">$ BACKUP WASD_ROOT:[000000...] location:WASDROOT.BCK/SAVE/VERIFY
$ ZIP "-V" location:WASDROOT.ZIP device:[WASD_ROOT...]*.*
$ ZIP "-T" location:WASDROOT.ZIP
</div>
<p> If using ZIP then ensure that a previous version of the target ZIP file
does not already exist. If it does then that version is updated, a new
version is not created.
<li class="item"> For existing files a new version is created (the first time this is about
to occur the UNZIPper requests permission – either "A" for all, or
"y" or "n" or a per-file basis).
<li class="item"> It is possible to <span class="high italic">selectively</span> extract portions of a tree if
something has become damaged. This would be accomplished by specifying what
needs to be extracted from the archive (instead of the default
<span class="high italic">all</span>), as illustrated by the following example where only the Alpha
object modules are extracted.
<div class="blockof code">$ SET DEFAULT device:[000000]

<p> Updating a package follows a similar process to installation.
<p> The ZIP archive will contain brief installation instructions. Use the
following command to read this and any other information provided.
<div class="blockof code">$ UNZIP -z device:[dir]archive.ZIP
</div>
<p> It is recommended to check the integrity of, then list the contents of, the
archive before UNZIPing.
<div class="blockof code">$ UNZIP -t device:[dir]archive.ZIP
$ UNZIP -l device:[dir]archive.ZIP
</div>
<p> The archive contains the complete directory tree. Hence it is necessary
to SET DEFAULT into the parent directory of the WASD_ROOT logical name, as with
the following example.
<div class="blockof code">$ SHOW LOGICAL WASD_ROOT
"WASD_ROOT" = "DKA100:[WASD_ROOT.]" (LNM$SYSTEM_TABLE)

to modify local startup procedures in-line with this new top-level directory

The WASD OpenSSL kit is designed as an update to an existing WASD installation

<p> The UPDATE.COM procedure assists with subsequent updates of WASD.
It assumes a <span class="high italic">vanilla</span> setup, using the standard directories and
account environment described in this document. All sections prompt before
performing any action and generally default to "no". Read the questions
carefully!
<p> Of course it is best (read mandatory) for the server to be shut down during
an update!
<div class="blockof code">$ HTTPD/DO=EXIT/ALL
</div>
<p> After UNZIPing the updated package do the following:
<div class="blockof code">$ SET DEFAULT WASD_ROOT:[000000]
$ @UPDATE
</div>
<p> It provides the following functions:
<ol class="list">
<li class="item"> <span class="high bold">Build Executables – </span>
Either compile sources and link, or just link package object code to produce
images for the local version of VMS. If the system has a suitable SSL toolkit
the installer is requested whether an SSL enabled version be built.
<li class="item"> <span class="high bold">Server Quick-Check – </span>
Executes a procedure that runs up the HTTPd in demonstration mode. Allows
evaluation/checking of the basic package (<a class="link" href="install002.html#2.10.quickcheck">2.10 Quick-Check</a>).
<li class="item"> <span class="high bold">Server Support/Configuration Files – </span>
Copies changed example HTTP server configuration and support files from the
[EXAMPLE] directory to the [HTTP$SERVER], [LOCAL] and [STARTUP] directories.
<li class="item"> <span class="high bold">Update Scripts – </span>
Selectively copy groups of scripts from package build directories into the
scripting directories.
<li class="item"> <span class="high bold">Reapply Package Security – </span>
This section traverses the updated tree and sets all package directories and
files to required levels of access. For directory settings see
<a class="link blank" target="_blank" href="../config/#recommendedpackagesecurity">Recommended Package Security</a> in <a class="link blank" target="_blank" href="../config/#0.">WASD Configuration</a>.
<li class="item"> <span class="high bold">Post-Update Cleanup – </span>
Prompts for permission to execute the post-update procedure described below.
<li class="item"> <span class="high bold">Purge Files – </span>
Prompts for permission to purge the entire WASD_ROOT:[000000...] tree.
</ol>
<p> If declined during the update procedure the post-update steps 6 and 7 can
be performed at any subsequent time using
<div class="blockof code">$ SET DEFAULT WASD_ROOT:[000000]
$ @UPDATE CLEANUP
$ PURGE [...]

<a id="3.3.relinking" href="#"></a>
<a id="relinking" href="#"></a>
<h2 class="head"><span class="numb">3.3</span><span class="text">Re-Linking</span></h2>
<p> After a major update to the operating system the package may refuse to
start, reporting the message
<div class="blockof code">%DCL-W-ACTIMAGE, error activating image WHATEVER
-CLI-E-IMGNAME, image file DKA0:[SYS0.SYSCOMMON.][SYSLIB]WHATEVER_SHR.EXE
-SYSTEM-F-SHRIDMISMAT, ident mismatch with shareable image
</div>
<p> This implies the executables require re-linking for your particular version
of VMS. This can be accomplished quite simply, perform the linking section
only of the UPDATE.COM Procedure.
