Introduction

Preview Server is available for customers to view a preview of the new features of Voyager before upgrading to a new software release or version.

There are three types of Preview Server:

Local Client Preview Server – You can test the Voyager clients of the latest voyager release by downloading the clients from the documentation center. You are able to see all of the client feature updates and enhancements. If there is a client feature that depends on server side changes, those features are not enabled. This is to ensure that customers experience the functionality of the software without special customizations for any specific institution or workflow. Also, your changes might not remain in the Ex Libris environment for the duration of your testing. If at any point a refresh of the preview server is required, this refresh may be performed without notice.
Remote OPAC Preview Server – Using an environment that is setup and hosted by Ex Libris, you can connect your browser to an Ex Libris provided URL to preview the basic functionality of the OPAC. You cannot make any changes to the display of the OPAC and you cannot preview the OPAC’s extensive feature set. With this option, you can see what changes have been made out‐of‐the‐box for the new release. You can compare the new version of the OPAC with what is available in your installation using an unmodified skin.
Local OPAC Preview Server – If you are primarily interested in making customization changes to the OPAC in preparations for your Voyager upgrade, use the local OPAC Preview Server installation. The local preview server installation is the third component of preview server and allows you to test the OPAC in a local setting prior to the upgrade. This option gives you access to the XSL, CSS, and configuration files necessary to making changes to the look and feel of the OPAC. This feature can be valuable and reduce the stress of going through the Voyage upgrade process by making the necessary changes to the OPAC skins prior to your upgrade date. When you upgrade, you can then copy the skins from the preview server into your production environment. This feature can be particularly useful if you do not have a test server environment to receive the latest version prior to your production environment upgrade.

This document explains how to connect to these three options so that you can test the new features and prepare for your upgrade.

Requirements

Browser Requirements

For browser requirements to use the Remote OPAC Preview Server and the Local OPAC Preview Server, refer to the Voyager Installation and Upgrade Requirements document.

System Requirements

Refer to the Voyager Installation and Upgrade Requirements document for the minimum requirements for installing the Voyager clients on your PC.

If you already have Voyager clients on your local PC, be sure to install these clients in a different location – do not overwrite your current production clients.

Local Preview Server Requirements

The Voyager Installation and Upgrade Requirements document contains the packages necessary to run the local OPAC and Client Preview Servers. Ensure that your system has all of the system packages for your Voyager serverʹs operating system and that all requirements have been met.

Local OPAC Preview Server Requirements

Outbound access to downloads-na.hosted.exlibrisgroup.com port 10022 must be configured on the server in order to download the Preview Server package, and other Voyager products.
Outbound access to preview1.hosted.exlibrisgroup.com and preview server ports 9814 and 9914 must be configured on the server.
One (1) external port (by default 7098) is required for WebVoyáge and Skin Administration. Ensure that this port is available through your firewall. For information on changing the default port, see Appendix A: Changing the Default Port for Preview Server.
Root access is not required for this installation

Installing the Local Client Preview Server

To set up the local client Preview Server:

Download and install the clients from the Documentation Center. (For more information on how to download and install the Voyager clients, refer to the Voyager Technical Userʹs Guide.)

Installing Voyager Skins

The preview server installer provides the option to generate an auto‐customized version of the newest Voyager skins for you. The new skin is named <xxxdb name>-<Skin Name>-<Voyager Release> and placed in /m1/incoming/PREVOY1030/tomcat/vwebv/context/vwebv/ui with the template skins and uncustomized skins that the preview server has created.

During the automatic customization process, any new skin files are added to your skin. Skin files that you have not customized are replaced with the newest version of those files.

The skin converter tries to isolate your customizations and apply them to the new skin files. Note that this is not a consistently successful process. More information about this is provided later in this section.

See below for an example skin customization session.

When Auto-Customization Fails

The auto‐customization tool tries very hard to apply all of your skin customizations to the new Voyager skin files. But sometimes this is not possible. When the auto‐customization does not work, you see a message like the following:

htdocs/help/index.html appears to be based on v2007.0.4 . We weren't able to completely update it to version 2010.3.0

        Hunk #1 FAILED at 139.

        1 out of 1 hunk FAILED -- saving rejects to file htdocs/help/index.html.rej

============================================================

    Review the file htdocs/help/index.html.rej

    for a list of customizations that we couldn't automatically

    make.  Manually apply these customizations to

    htdocs/help/index.html_autocustomized

    Then copy it back to htdocs/help/index.html

============================================================

When this happens, be aware of the following:

When the installer is unable to apply your customizations to the new skin file, a copy of your old skin file is made in place of the new skin file. In the above example, the htdocs/help/index.html file in your new skin is the same one that you were using in the old skin.
Since the customization tool is often able to apply some of your customizations to a file, even if it is unable to do the whole thing, the file is saved that was worked on as <filename>_autocustomized. In the above example, the partially customized file is named htdocs/help/index.html_autocustomized.
The installer saves the customizations that could not be completed to the file called <filename>.rej. Using the above example, the file is named htdocs/help/index.html.rej. The rej file is in Unified Diff format.
To apply the rejected customizations to your file, first review the rej file to determine how much work need to do. In the following example, it is relatively clear:

--- htdocs/help/index.html-version_2007.0.4     2018-04-16 16:27:12.000000000 -0400

This means that this section starts on line 139 of the uncustomized file, and was originally seven lines long. The +139,7 means that the section starts on line 139 of the customized file, and is still 7 lines long.
4. Lines following this that do not begin with a special character are unchanged. They are provided for context.
5. Lines beginning with a - (hyphen) character are the original lines in the original file. Look for something like these in the new file that you are customizing. Note that what you find will not look quite the same.
6. Lines beginning with a + (plus) character are the replacement, custom lines.
7. Many times there are - lines and + lines together, but some customizations only add or remove lines from a file.
Open the autocustomized file (like htdocs/help/index.html_autocustomized). For each - line and each + line, look for where that ought to fit. It is likely to be near where it was in the old file, so start around there. Look for unique strings in, or near the lines that you need to change, like div Id=”pageFooter” or copySymbol.
After you have applied or discarded all of the rejected customizations from your rej file, back up your old uncustomized file and replace it with the new autocustomized file that you worked on:

cp htdocs/help/index.html htdocs/help/index.html.orig
cp htdocs/help/index.html_autocustomized htdocs/help/index.html
If you want to start over with a new, uncustomized copy of the file you can find that in /m1/incoming/PREVOY1030/tomcat/vwebv/context/vwebv/ui/exl_default.

Even though the auto‐customization tool makes every effort to apply all of your skin customizations to the new Voyager skin files, remember that it is not always successful; and it is important that you test all of your customizations in the preview server. You should also test again with your own data and configuration after the upgrade.

Note that the automatic customization tool is meant to encourage you to use the best quality skins, but support for automatically customized OPAC skins remains at the same level offered for your manually customized skins.
