This section provides information about the commands used to initialize and
maintain the TPFCS database.
- Note:
- Most of the functionality achieved by using the commands can also be
implemented by writing applications that use the TPFCS APIs.
The ZOODB commands are used to initialize the TPFCS database, define and
display a data store or data definition, and change or delete a data
definition. The following describes the ZOODB commands:
- Function
- Description
- ZOODB CHANGE
- Changes a data definition or data store.
- ZOODB DEFINE
- Defines a data definition or data store.
- ZOODB DELETE
- Deletes a data definition or data store.
- ZOODB DISPLAY
- Displays a data definition or data store.
- ZOODB INIT
- Initializes support.
- ZOODB MIGRATE
- Migrates a data store.
- ZOODB RECREATE
- Re-creates a data store.
- ZOODB SET
- Sets on or sets off the method trace table or set dump creation on a
TO2_getErrorText function call.
- Note:
- For more information about the ZOODB commands, see TPF
Operations.
The ZOODB INIT command is a one-time-only message that is used to
initialize TPFCS. If you attempt to initialize TPFCS again, an error
message will be displayed.
After the ZOODB INIT command has been completed successfully, enter the
ZOODB DEFINE command with the DS parameter specified to create user-defined
data stores.
TPFCS provides browsing support that allows classes, methods, and
collections to be located, interrogated, validated, displayed, and
dumped. This support is provided by using the ZBROW commands and TPFCS
function calls.
The following describes the ZBROW commands:
- Function
- Description
- ZBROW ALTER
- Changes the contents or access mode of a specified collection.
- ZBROW CLASS
- Displays class name information.
- ZBROW COLLECTION
- Performs maintenance on a collection.
- ZBROW DISPLAY
- Displays information about a collection or its contents.
- ZBROW KEYPATH
- Adds, displays, or removes a key path.
- ZBROW NAME
- Alters or displays collection name information.
- ZBROW PATH
- Displays path information for a collection structure.
- ZBROW PROPERTY
- Alters or displays a property.
- ZBROW QUALIFY
- Qualifies ZBROW command requests for a data store.
- ZBROW RECOUP
- Manages recoup indexes.
See TPF Operations for more information about the
ZBROW commands. See the TPF C/C++ Language Support
User's Guide for more information about the TPFCS C function
calls.
