Manage Your Source Data Assets . . .

. . . with RAD Harvest Interface

Once the settings are established on the preferences menu and the Harvest repository is available you can then navigate through the repository to begin performing SCM activities (check-out, check-in, promote, demote, etc.). Harvest is right mouse-click driven so all the processes that an individual user will have available will be viewable with a right mouse-click on any file or any state view (see Figure 10).

Figure 10

Doing a right mouse-click on any file provides many options. The developer can copy, delete, move, rename, import, export, use the team menu to perform checkouts, check-ins, view the properties of files, and make comparisons between versions (see Figure 11).

Figure 11

When a developer does a right mouse-click on a file the following dialog screen appears (see Figure 12). This is where the developer can identify the mode of checkout (Read Only or Update), the option (All Files to the Same Client Directory or Preserve and Create Client Directory), Select the Package to use for the Check out (if you are performing a read-only check-out no package is required), select the path in the Harvest repository where the file is located that you will be checking out, the To: field where you would like the file to be checked out to, the selection of the file to be checked out (if there is no file identified in this field then no file will be checked out), and several other options to: Replace read-only files, Replace writable files, and last you can Create empty directories.

If you were performing a checkout and wanted to preserve an entire directory structure upon checkout, and some of those directories were empty you could preserve those directories upon checkout with this flag set. Once this screen is accurately filled in, you can click the OK button or hit the Apply button and the checkout will be invoked. When your checkout has been performed there is a session log to the right at the bottom that records the results of that checkout (whether it was successfully completed or not) and there is a properties screen that provides valuable information about the file that was checked out (date, size, user, etc.). In this checkout example (see Figure 12) if you look closely, you can see there are files that have the letter (N) associated with them that identifies a normal status for the file. When a successful checkout occurs, the file will acquire the letter (R), which identifies that the file is reserved by an individual user and cannot be checked out by any other user until this file has been officially checked back in and has the letter (N) on the file, then it is available for another user to acquire for check out.

Figure 12

Figure 13 clearly shows the session log and provides error codes should a checkout fail; you can then view the error message guide where the definitions of the error codes are listed so that issues can be identified and resolved. The session log also provides the path of the checkout, the version of the file checked out, the date and time stamp, and whether the checkout was successful or not.

Figure 13

Once the checked-out file has been modified and ready for check-in, the user will right mouse-click the file and the dialog screen shown in Figure 14 will become available. Harvest is aware of the file, has the path where the file was checked out to and understands where the file has to be checked back into as well as provides the next version placeholder (e.g., if version zero were to be checked out, Harvest knows to provide version one as the next incremented version number). The default mode for check in is "Update and Release," which checks the file into the repository and the reserve tag is removed. However, there is also "Update and Keep" which updates the file in the view but keeps the file reserved so that you can continue to make changes to it, and, last "Release Only" which does not check the file in or update the file and releases the reserved tag so that it is available for check out by another user.

Once a file has been checked out you'll see a letter -r (reserved) on the file. This represents a checked-out or a reserved file. As long as this file has a reserve tag on it, no other user can check this file out until it has been checked back in by the owner of the reserve tag. Once the file has been checked out, updated and ready to be checked back in, you do a right mouse-click on the file and the dialog screen shown in Figure 14 appears. Harvest and the IDE are aware of the file, path and new version, which will be applied to the file upon check-in. There is a flag that can be set to delete the file(s) after check-in as well. Some folks like to leave a read-only file available for viewing so the delete file flag after check-in would not be set.

Figure 14

Harvest provides excellent status accounting of files. If you review the session log shown in Figure 15 as well as the properties dialog to the left of the session log, you can review the activities that have occurred and see that Harvest incremented the version to the next version level. You can review the size change, date, user name, path, etc.

Figure 15

In the RAD IDE when using the Harvest Explorer tab, if you do a right mouse-click on any file, you can view the processes that are available to you as assigned by your Harvest administrator for your level of access. You can also view the status of a file by looking in the Harvest repository view (see Figure 16).

Figure 16

Harvest provides the ability in the RAD IDE to compare versions of files whether you're in the IDE or dragging and dropping files into the compare screen (see Figure 17).

Our Experience
We develop and maintain more than 146 applications at New Hampshire's Department of Information Technology. The applications are used extensively in our welfare and health services delivery agencies. Example applications are for child-care licensing and managing adult and elderly care. Throughout the state the applications are used by hundreds of users.

My Synopsis and Review of the SCM AllFusion Integration with RAD 7.5 and the CA SCM Eclipse Plug-In are as follows:

Using SCM AllFusion Harvest R12 with RAD 7.5 and the Eclipse plug-in has made securing and controlling Java objects for source code management an easy task. CA SCM AllFusion Harvest R12 and the RAD Eclipse plug-in from the environment use processes built into the products; interfacing capabilities and ease of use makes this a seamless integration.

The ease of the CA SCM Version Control Interface (VCI) intertwined with the Eclipse IDE is a great example of how tools should work together. I'm also pleased with the way in which connectivity can be re-established even when a disconnect occurs. It just requires adding the workspace again from the Harvest Repository tab and you're off and running.

If you were in an environment where you require products that encompass the best seamless interfacing capability into RAD, using the CA SCM Eclipse plug-in for source code management would benefit you greatly. Using CA SCM AllFusion Harvest R12 with the RAD Eclipse plug-in is a great way for you to manage your source data assets.

Please feel free to contact me should you have any questions regarding the product (CA SCM AllFusion Harvest) and its use in our environment with various development tools.
