  Data Members

Class Description

 rooFDObj corresponds to ooHandle(ooFDObj) class

 Handle class for fedrated databases

 default ctor.

 copy ctor.

 bootFile -  path to the boot file of the federated database.
             The default value is "".
 lockServer - name of the new host running the lock server
             process for this federated database. The default
             value is "".
 fdNumber -  new identifier of the federated database
 fp       -  pointer to the transcript file to which the
             system name of the federated database, the
             lock server host name, and the identifier of the
             federated database are echoed before and after
             the change member function is invoked. The
             default value is stdout.

 Change federated database attributes. If any of the
 first three arguments has a value other than zero, then the catalog
 information corresponding to that argument is set to the specified
 value. Catalog information corresponding to arguments with zero
 values is not modified. After calling change, the old boot file remains.
 You must delete this file manually.

 When using the rooFDObj::change member function
 to modify the attributes of a federated database, you must strictly
 follow these steps:

    1. Shut down the lock server.
    2. Run in single-user mode (call ooNoLock in your program).
    3. Start a transaction.
    4. Open the federated database for update.
    5. Invoke the rooFDObj::change member function.
    6. Commit the transaction.
    7. Exit from the process.
    8. Restart the lock server.

 The federated database attributes are in a new and different state after
 the rooFDObj::change member function has been run. For this reason, it
 is mandatory to exit from the process immediately after changing
 attributes.

 Closes the referenced federated database

 Initializes the iterator itr to traverse all databases in the referenced
 federated database. Objects of the iteration are automatically opened in
 the mode specified by openMode. The default is kooNoOpen (do not
 open the federated database automatically).

 Convert all objects affected by schema evolution operations within a
 federated database to their current class representations. Schema
 information used for object conversion will be purged as a side-effect of
 this operation.

 OBSOLETE ???

 fp    -  pointer to the output file that stores the
          federated database attribute information
          normally printed in the standard output by the
          oodumpcatalog tool. The default value is stdout.
 fileNameFormat - flag indicating the format of the printed file
          name. The default value is kooHostLocal,
          which formats the file name as host:localPath. The
          other allowable value is kooNative, which
          formats the file name as a full path name or
          just a local name (for example, /net/object/usr/mnt/ed/dsgn/up.FDB).
 printLabels - specifies whether or not to label the file in the
          output. The default is oocTrue, which specifies
          that each file name in the output is labeled.

 OBSOLETE ???

 Tests for the existence of the federated database specified by boot file
 bootFile. If the federated database exists and openMode is
 kooRead or kooUpdate, the federated database is opened and its object
 reference or handle is initialized. If openMode is not kooNoOpen, and
 exist returns kFALSE, the object either does not exist or the object
 exists but is not accessible.

 Checks the validity of an object reference or handle.

 Explicitly locks the federated database and propagates the lock to any
 objects associated through links that have lock propagation enabled.

 Retrieves the name of the host running the lock
 server process for the federated database.

 Returns the system name of the referenced federated database. The
 string is statically allocated by the member function and is overwritten
 with each invocation (you may wish to copy the string to locally
 allocated storage rather than storing the pointer).

 Retrieves the identifier of the federated database.

 bootFile -  path to the boot file of the federated database.
             The default value is "". You can specify this
             path with or without a host name. If you specify
             it as a host path, use the format host::path.
 openMode -  specifies the open mode for the federated database.
             Valid values for openMode are the constants kooRead
             and kooUpdate. The default open mode is kooRead.
 recover -   specifies whether automatic recovery on the local
             host should be performed on application startup.

 Initializes object reference or handle to reference the federated
 database specified by bootFilePath. The federated database is
 opened in the mode specified by openMode.

 Any number of processes may open the same federated database for
 either read or update access as long as no other process has obtained
 an explicit lock on it using the lock member function. If a process has
 obtained an explicit read lock, any other process may open the
 federated database for read access. If a process has obtained an explicit
 update lock, no other process may open it.

 If you intend to alter the contents (any objects it contains) of a
 federated database, you must open it for update access, or any changes
 made will be lost.

 Returns the mode in which the currently referenced federated database
 has been opened.

 Obtains the page size of the federated database.

 fp    -  pointer to the file in which to store the audit
          report generated by running the member function
 hostName - specifies the name of the host machine on
          which to create the scratch file.
 pathName  - specifies the path for the scratch file.

  Tidies all of the databases in a federated database.

 Type number of the federated database.

 Returns the string "ooFDObj"

 Opens the referenced federated database in update access mode.

 Convert objects using stored schema evolution information and
 user-defined functions (if any).

 After object conversion is complete, the evolved classes are marked so
 that applications created using the evolved schema can access the
 federated database. Also, unneeded stored schema evolution
 information is deleted upon successful completion.
