Chapter 10: Using Repository Versioning

Creating and restoring versions

Using EAServer Manager, you can create versions for any repository entity type listed in Table 10-1.

**Table 10-1: Version data for each entity type**
Entity type	Version data contains
Server	For major and minor versions, includes only configuration properties for the server. WARNING! Unlike the application entity type, the server version data does not include installed applications, packages, or Web applications. You must create versions of these entities yourself.
Application	Includes application properties data, plus version data for each Web application and package in the application. Major versions include package and Web application implementation files, as described below.
Package	Version data for the package plus version data for each component installed in the package. A major version includes: Package property settings Package files (the file set indicated by the com.sybase.jaguar.package.files property) Major version data for each component in the package For each component, implementation files (the file set indicated by the com.sybase.jaguar.component.files property plus the component implementation files). The major version file set is the same as would be included if the package were archived in Jaguar JAR format. A minor version includes only package properties and minor version data for each component in the package.
Component	Major and minor versions include only configuration properties.
Web Application	A major version includes configuration properties and implementation files (the entire context root directory including the WEB-INF subdirectory), plus major version data for installed Web components. A minor version includes only configuration properties for the Web application and for installed Web components.
Servlet or Web Component	Major and minor versions include only configuration properties.
J2EE Client	A major version includes configuration properties and implementation files. A minor version includes only configuration properties.

Manually creating a new version

Highlight the entity of interest.
Select File | Versioning, then select:
- Save Minor Version to create a new minor version, or
- Save Major Version to create a new major version.
Enter a comment describing the version and click OK.
EAServer Manager creates a new version archive for the entity. If the entity contains nested entities (see Table 10-1), EAServer Manager creates new versions for each nested entity.

Viewing version history

Version history shows the version number, creation date, and comment for all available versions of an entity. To display version history:

Highlight the entity of interest and select File | Versioning | List Versions.
EAServer Manager displays a list of version numbers, creation dates, and the corresponding comments.

Restoring a version

Restoring replaces the current configuration and implementation files with the saved version files.

WARNING! Restore overwrites the current configuration and implementation. Save the current version first if you may need to restore it in the future.

To restore a version:

Highlight the entity of interest and select File | Versioning | Restore Version.
EAServer Manager displays a list of available versions and the corresponding comments.
Highlight the version to be restored, then click OK.

Deleting a version

Deleting removes the version data and archived files so the version can no longer be restored. To delete a version:

Highlight the entity of interest and select File | Versioning | List Versions.
EAServer Manager displays a list of available versions and the corresponding comments in the List Versions dialog box. Highlight the version to delete, and click Delete.
