26 Managing Archives, Collections, and Batch Files

This chapter describes the Archiver utility and how to use it to archive Content Server content.

This chapter covers the following topics:

26.1 Understanding How the Archiver Works

Archiving Content Server content consists of three elements: the archive itself, a collection, and a batch file. This section describes the structure of the Archiver and how it uses collections and targets. For an overview of the Archiver and how it compares to other archiving tools, see Section 24.1.

26.1.1 Archive Structure

An archive is a set of exported content files and their associated batch files. Each archive has its own subdirectory in the collection it belongs to.

Caution:

Do not edit any of the files created by Archiver.

Figure 26-1 Archive Directory Structure

Description of Figure 26-1 follows
Description of "Figure 26-1 Archive Directory Structure"

An archive subdirectory includes the following:

File or Directory Description

Batch file directories

Each batch file has a subdirectory in the archive. The subdirectory name reflects the date and time of the export, with a default format of yy-MMM-dd_HH.mm.ss_SSS. For example, 03-feb-04_15.04.14_174.

temp directory

Contains transferred Zip files.

archive.hda file

Specifies information about the archive, such as export and import settings, the export query, field and value import maps, archiving history, and so forth.

doctypes.hda file

Lists the content types (DocTypes database table) in the source Content Server instance. This file is present only if content types were exported.

exports.hda file

Specifies the batch files that are included in the archive.

users.hda file

Lists the user attributes (Users database table) in the source Content Server instance. This file is present only if user attributes were exported.

26.1.2 Collections

This section provides information about collections.

Summary

A collection is a set of archives on a particular Content Server instance.

  • Each instance has a default collection, which is located in the IntradocDir/archives/ directory. Additional collections can be created, but are necessary only in rare situations. For example, you could create a new collection if you want to save disk space by archiving to another system that does not have Content Server on it.

  • Collections can be created only through the standalone Archiver utility. For details about using the standalone Archiver, see Section 26.2.5.

  • A collection can be removed from a Content Server instance, but this only makes it unavailable from the Archiver application; the archive and batch files remain until you delete them from the file system.

    Tip:

    Archiver collections are normally compatible between different versions of Content Server instances. One possible exception would be User Configuration information that was archived from a pre-3.0 version Content Server instance. The format of the Users database table changed in version 3.0, so this information might not be compatible between pre- and post-3.0 version Content Server instances.

Structure

An archive collection includes the following:

File or Directory Description

collection.hda file

Specifies the archives that are included in the collection.

collection.mrk file

Internal file used by Archiver.

Archive directories

Each archive has a subdirectory in the collection.

26.1.3 Batch Files

This section provides information about batch files.

Summary

A batch file is a text file that contains the file records for archived content items. Batch files describe the metadata for each exported revision.

  • A new batch file subdirectory is created each time an archive is exported.

  • Each batch file contains up to 1000 file records. If an export contains more than 1000 revisions, a new batch file is created.

    Note:

    Archiver batch files are not the same as the batch files that are used with the Batch Loader application.

Structure

A batch file subdirectory includes the following:

File or Directory Description

Content files

A subdirectory named '1' in the batch file directory contains a vault structure that is copied from the source Content Server instance. If web-viewable files are being archived, this subdirectory also contains a weblayout structure.

Batch file

Specifies the metadata for each revision that was exported. Batch files are HDA files that are named with a unique number generated by Archiver. For example, 0335150414~1.hda.

docmetadefinition.hda file

Lists the custom metadata fields in the source Content Server instance (DocMetaDefinition database table). This file is used by Archiver to create import maps.

26.1.4 Archive Targets

You can use Archiver to archive the following content:

  • Native files with associated standard metadata values

  • Web-viewable files (.pdf, .html, and so forth)

  • Metadata fields and changes

  • User information fields

  • Security groups (user attributes and settings)

  • User updates

  • Subscription types

  • File formats

  • Document types

  • Content types

  • User attributes (such as user login, full name, password, email address, and so forth)

    Note:

    Content types and user attributes can be exported and imported manually, but cannot be transferred or archived automatically through replication. Table replication can be used, though, to replicate user information.

    Caution:

    Archiver cannot be used to move or copy data between two instances that share the same Content Server instance name (IDC_Name). To do so will corrupt the data on the target system.

26.1.5 Using Archive Logs

If you are experiencing Archiver problems, view the Archiver logs for more information.

Summary

The Archiver logs are listed by date and time. They are generated once per day when the first Archiver information status, irrecoverable error, or error occurs.

Click the Archiver Logs link on the Administration page to view information about imports, exports, and replications.

Click the link that appears for the desired log file. A table showing the type, date and time, and description of each action is displayed. It also includes the name of the Content Server instance that created the archive.

Log Entries

The following types of archiver log entries are generated:

  • Info: Displays basic status information. For example, status information is logged when an export and an import starts and finishes.

  • Error: Displays user and administration errors that occur but do not stop the software from functioning. For example, an error is logged if there is no file information for a content item that you are trying to export.

  • Fatal: Displays errors that stop the software from functioning. For example, an irrecoverable error is logged if the Content Server instance cannot access the database. Check the connection string, user name, and password.

26.2 Managing Archives

After archives are created, they can be added to collections and manipulated as a group.

26.2.1 Creating a New Archive

To create a new, undefined archive:

  1. Display the Main Archiver window in either standalone or browser mode.

  2. If necessary, open the collection where you want to create the new archive. For more information, see Section 26.3.1.

  3. From Edit, select Add.

  4. In the Add Archive window, enter the archive name and description. The archive name cannot contain spaces.

  5. Click OK.

26.2.2 Copying an Existing Archive

To copy an existing archive to a different directory location:

Note:

This procedure copies the files in an archive. It does not create a new collection or update the collection.hda file if the archive is copied to a collection directory.

  1. Display the archiver in standalone mode.

  2. If necessary, open the collection that contains the archive to be copied. For more information, see Section 26.3.1.

The following information details how to run the Archiver as a standalone application, which is required to create collections.

To run Archiver in Windows:

To run Archiver on a Windows operating system:

  1. Select the application from the Windows Start menu, then choose Programs, then Content Server, then instance, then Analyzer. A login window or application window opens.

    Tip:

    It may take several seconds for the login window or the application window to appear, and the window may be hidden by other windows.

  2. If required, enter the administrator login name and password, then click OK. The Main Archiver window opens.

To run Archiver in UNIX:

To run Archiver on a UNIX operating system:

  1. Navigate to the DomainHome/ucm/cs/bin/ directory.

  2. Enter ./archive

  3. If required, enter the administrator login name and password. The Main Archiver window of the application opens.

26.3 Managing Collections

Collections are a set of archives and are used to group archives for different archive functions.

Note:

The standalone mode of the Archiver application is required to create new collections or browse the local file system to connect to new collections.

26.3.1 Opening a Collection

To open an existing archive collection:

  1. Run the Archiver in standalone mode. See Section 26.2.5.

  2. From Options, choose Open Archive Collection.

  3. Select the collection from the list of existing collections on the Open Archive Collection window (shows the default collection and any other connected collections).

  4. To browse to a new collection, use one of these methods:

    To select the collection from a shared file system location (standalone Archiver only):

    1. Click Browse Local.

    2. In the Find Archive Collection Definition File window, navigate to and select the collection HDA file.

    3. Click Open. The Browse to Archiver Collection window opens.

    To select the collection from a remote Content Server instance:

    1. Click Browse Proxied. The Browse for Proxied Collection window opens with a list that includes all Content Server instances to which an outgoing provider has been set up.

    2. Select the Content Server instance in the Proxied Servers list.

    3. Select the collection in the Collections list.

    4. Click OK.

26.3.2 Creating a Collection

To create a new archive collection:

Note:

You can create a new collection only on the local Content Server instance using the standalone Archiver.

  1. Run the Archiver in standalone mode. See Section 26.2.5.

  2. From Options, choose Open Archive Collection.

  3. In the Open Archiver Collection window, click Browse Local.

  4. In the Find Archive Collection Definition File window, navigate to and select the directory where you want to create the new collection.

  5. Enter a file name for the new collection (collection.hda is the default).

  6. Click Open. You are prompted to create a collection definition (HDA) file.

  7. Click Yes.

  8. In the Browse To Archiver Collection window, enter a collection name in the Name field.

    • Collection names cannot contain spaces.

    • Use the same name for a collection and its directory to make navigation easier.

  9. Enter the directory path for the weblayout and vault directories in the Web Directory and Vault Directory fields.

    • Use the same path style as shown in the Location field.

    • To find the directory paths, display the Configuration Information Page.

  10. Click OK. The new collection is shown in the Open Archive Collection page.

  11. Click Open to open the new collection.

26.3.3 Removing a Collection

To remove an archive collection:

Note:

You cannot remove the default collection.

  1. From Options, choose Open Archive Collection.

  2. In the Open Archive Collection window, select the collection to be removed.

  3. Click Remove. You are prompted to confirm the action.

  4. Click OK. The collection is removed from the Content Server instance. (The collection and archive files remain in the file system, and must be deleted manually.)

26.3.4 Moving the Default Archive Collection

You can change the file system location of the default archive collection by moving the collection and pointing the Content Server instance to the new location. For example, you might want to keep all of your archive data on a separate drive from the program files for easier backup and expansion.

Note:

The default collection is the archives/ directory.

To move the default archive collection:

  1. For data safety, close any standalone Archiver applications and stop the Content Server instance.

  2. Add the CollectionLocation configuration variable to the DomainHome/ucm/cs/bin/intradoc.cfg file:

    CollectionLocation=path
    
  3. To maintain the previously created archives for the default collection, move the contents of the archives/ directory to the new location you specified in the CollectionLocation setting. If you do not move the contents, the system will create an empty collection.

  4. Start the Content Server instance.

    Note:

    The Content Server instance re-creates the default Domain_home/ucm/cs/archives/ directory when it is restarted, but the Archiver defaults to using the collection in the new location.

26.4 Managing Batch Files

A batch file describes the metadata for exported revisions. A batch file is created each time the Archiver performs an export.

26.4.1 Removing Revisions from a Batch File

To remove individual revisions from a batch file:

  1. Open the archive collection. See Section 26.3.1.

  2. Select the archive in the Current Archives list.

  3. In the Main Archiver window, click View Batch Files.

  4. In the View Batch files window, select the batch file.

  5. Click Edit.

  6. In the View Exported Content Items window, use the Filter element and the navigation buttons to display the revision to be deleted.

  7. Select the revision to be deleted.

  8. Click Delete. The Status changes to Deleted for the selected revision.

  9. Repeat steps 7 and 8 to delete additional revisions.

  10. To undo the last deletion, click Undo. To return all deleted revisions to Archived status, click Refresh.

  11. Click Apply to delete the specified revisions.

  12. Click Close.

26.4.2 Deleting a Batch File

To delete a batch file from an archive:

  1. Open the archive collection. See Section 26.3.1.

  2. Select the archive in the Current Archives list.

  3. In the Archiver window General tab, click View Batch Files.

  4. In the View Batch Files window, select the batch file to delete.

  5. Click Delete. You are prompted to confirm the action.

  6. Click OK. The batch file is deleted from the archive.

  7. Specify whether to replace existing batch files upon export:

    • To delete all existing batch files when the next export is initiated, select Replace Existing Export Files.

    • To leave existing batch files in place when the next export is initiated, deselect Replace Existing Export Files.

  8. Specify which files to export:

    • To export the native (vault) and web-viewable (weblayout) files, select Copy Web Content.

    • To export only the native (vault) files, deselect Copy Web Content.

  9. Click OK. The export options are displayed in the Export Options section of the General tab.
