Source-Navigator Version 4.2

Source-Navigator (SN) is an extendable source code editor, organizer and analysis tool.
Installation

SN Developer and Enterprise Editions are supported on at least Sun Solaris 2.5.1, SuSE 6.0/6.1 or Red Hat 6.0. It is also supported on Wintel platforms running NT 4.0 and Windows 95/98. The Enterprise Edition is also supported on HP-UX 10.20. Literature indicated SN should run on the Caldera Linux distribution. The platform used in this review used the Caldera v1.3 and v2.2 Linux distributions.

By default, the product is installed under the installer's ID in the installer's home directory. An option to install the Source-Navigator product according to your product install conventions is provided.

Source-Navigator is a breeze to install. First, start the install script from within the X environment. Next, enter the desired target installation directory and identify how any problem reports will be sent to Cygnus. The option of installing a demonstration project is offered once the above choices have been made. Any or none of the six demonstration projects can be selected for installation. The tutorial is based on the C++ demonstration project. A dialog keeps you posted on the install progress.

The product installed without problems the first time. On the Caldera v2.2 install, some of the subdirectories and files had UID and GID numbers that were nonexistent on my system. To correct this, I assigned valid user and group IDs to the subdirectories and files.

SN uses a network floating-license scheme to control product access. I didn't find installing the license manager asset-key as seamless as the install guide indicated. I had to manually create the license file to include the asset-key information.

Running the license manager under Caldera v1.3 was straightforward. It wasn't quite as smooth under Caldera v2.2. The license manager wants to place a lock file in /usr/tmp. This directory did not exist in my v2.2 installation. I chose to create a soft link between /usr/tmp and /tmp. This link allowed the license manager to create its lock file. On a side note, the license-manager documentation doesn't recommend running the license manager under the root ID.

Documentation and Support

Source-Navigator comes with a User's Guide and a Programmer's Reference Guide. The User's Guide clearly presents installation instructions, contains a tutorial on creating a project, and factually describes each of the Source-Navigator browsers. The Programmer's Guide serves as a reference for customizing and extending Source-Navigator functionality. Descriptions and narrations in each of these manuals are supported with screen captures. Where appropriate, sample code is included in the manual.

The Installation Guide clearly presented UNIX system memory, disk, X11 and printer requirements. Comparable Wintel requirements are also given. I found the example of UNIX memory utilization for startup, post-project creation and per open browser informative. The Installation guidance also provided a rule of thumb for estimating disk storage requirements on a per-project basis. The default directory table leaves little doubt as to what directories are being created and the type of files being placed in the directories.

Cygnus uses GLOBEtrotter Software's FLEXlm to manage the SN license. The User's Guide contained virtually no information on starting, stopping or checking the current status of FLEXlm. The only reference I could find about starting this license manager was in the asset-key e-mail. A list of available commands and options is displayed if you enter lmutil at the command line without any options. More can be learned about the FLEXlm license manager by going to the http://www.globetrotter.com/ web site; there you will find a FLEXlm FAQ and a User Manual.

There is a 17-page tutorial introducing project creation and the basic use of each browser and editor. The User's Guide portion of the manual provides more detail on each of the items covered in the tutorial. I found the tutorial worth the time.

Software Development Kit

Out of the box, SN supports seven languages: C, C++, Tcl, [incr tcl], FORTRAN, COBOL and assembly. An SDK is included with the base product. Using the included SDK, one can modify the graphical user interface, write a new parser to incorporate additional languages, build applications to access the SN project database and implement communications between SN and external applications.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
