How the Siebel Analytics Web Catalog Backup Process Works

Siebel Analytics Web maintains automatic Web Catalog backup files and version files in the location where the Web Catalog is stored. Web Catalog backup files are useful when the Siebel Analytics Web administrator is customizing or testing Siebel Analytics Web content. The version file is used to help maintain Web Catalog integrity.

About Siebel Analytics Web Catalog Backup Files

By default, Siebel Analytics Web performs a Web Catalog backup every five minutes. The backup files are saved into the same location as the in-use Web Catalog. Automatic backups are identified by nnn.autosave appended to the Web Catalog name, where nnn represents the sequential number assigned to the backup.

For example, in Windows, if the path to the Web Catalog is:

c:\SiebelAnalyticsData\Web\Catalog\SiebelAnalytics.webcat

then the third backup file is:

c:\SiebelAnalyticsData\Web\Catalog\SiebelAnalytics.webcat.03.autosave

The default number of Web Catalog backup files is 10. If the server crashes, it creates another set of 10 backup files. After ten sets of backup files have been created, the numbering goes back to 01-10.

You can control the number of automatic Web Catalog backup files and the interval between them. For more information, see Setting the Number of Automatic Siebel Analytics Web Catalog Backups and Setting the Number of Minutes Between Backups of the Siebel Analytics Web Catalog.

About the Siebel Analytics Web Catalog Version File

Information about the last known good Web Catalog backup is stored in a file ending in .version. For example, in Windows, using the example locations shown in About Siebel Analytics Web Catalog Backup Files, the current version of SiebelAnalytics.webcat would be tracked in:

c:\SiebelAnalyticsData\Web\Catalog\SiebelAnalytics.webcat.version

The version file is interrogated during Siebel Analytics Web startup:

• If the version file does not exist, the Web Catalog is read from the original path specified in the CatalogPath registry key. (For more information about this key, see Changing the Name and Location of the Siebel Analytics Web Catalog.)
• If the path does not exist, the Web Catalog is created in the default location for the operating system, described in Changing the Name and Location of the Siebel Analytics Web Catalog.
• If the version file exists, the backup file that it references (nnn.autosave) must also exist. If the backup file does not exist, Siebel Analytics Web will not start.

The version file is updated during Siebel Analytics Web shutdown. After a successful shutdown, the version file includes an entry indicating that the Web Catalog was successfully written to the original catalog path.

NOTE:  The Siebel Analytics Web shutdown process does not create a Web Catalog backup file.

When Changes Are Written to the Siebel Analytics Web Catalog

Changes made to the Web Catalog are written to the Web Catalog when the Analytics Web Server service is stopped. Until the service is stopped, changes are written to the current Web Catalog backup file.

When the Analytics Web Server service is started again, the Web Catalog is read, and any subsequent changes are written to the current backup file.
