181 DBMS_XDB

Note:

The DBMS_XDB package subprograms and constants are deprecated with Oracle Database 12c. While all features continue to be supported for backward compatibility, Oracle recommends that you use the alternative procedures provided in each case. For more information, see Deprecated Subprograms and Constants.

The DBMS_XDB package supports the following features:

Resource Management subprograms which complement Resource Views
The Access Control List (ACL)-based Security Mechanism
Configuration Session Management
Creation of the XDB username

Using DBMS_XDB

This section contains topics which relate to using the DBMS_XDB package.

Overview

The DBMS_XDB package supports the following features:

The Resource Management functionality providesLINK Procedures, EXISTSRESOURCE Function, LOCKRESOURCE Function, GETLOCKTOKEN Procedure, UNLOCKRESOURCE Function, CREATERESOURCE Functions, RENAMERESOURCE Procedure, DELETERESOURCE Procedure, GETRESOID Function, CREATEOIDPATH Function, and CREATEFOLDER Function subprograms which complement Resource Views.
The Access Control List (ACL)-based Security Mechanism can be used with in-hierarchy ACLs stored by the database or in-memory ACLs that may be stored outside the database. Some of these methods can be used for both Oracle resources and arbitrary database objects. Use CHECKPRIVILEGES Function, GETACLDOCUMENT Function, and CHANGEPRIVILEGES Function for Oracle Resources. ACLCHECKPRIVILEGES Function provides access to Oracle's ACL-based Security mechanism without storing objects in the Hierarchy.
Configuration Session Management is supported by CFG_REFRESH Procedure, CFG_GET Function and CFG_UPDATE Procedure. methods.
The XDB username is created during XDB installation. This user owns a set of default tables and packages. GETXDB_TABLESPACE Function and the DBMS_XDB_ADMIN.MOVEXDB_TABLESPACE Procedure enable movement of schemas to a specified tablespace, and support the default SYSAUX tablespace introduction

Deprecated Subprograms

Note:

Oracle recommends that you do not use deprecated subprograms in new applications. Support for deprecated features is for backward compatibility only and may be terminated in future releases.

All subprograms in the DBMS_XDB package are deprecated with Oracle Database 12c and substituted by the alternative subprograms with the same names in either the DBMS_XDB_CONFIG package or the DBMS_XDB_REPOS package as listed in the table.

Security Model

Owned by XDB, the DBMS_XDB package must be created by SYS or XDB. The EXECUTE privilege is granted to PUBLIC. Subprograms in this package are executed using the privileges of the current user. Subprograms that operate on the XDB Configuration will succeed only if the current user is SYS or XDB, or the current user has the XDBADMIN or DBA role.

Constants

All constants as described in Table 181-2, "DBMS_XDB Constants"are deprecated in Oracle Release 12c in that they are relocated to either the DBMS_XDB_CONFIG package or the DBMS_XDB_REPOS package. The specifics of transference in each case are detailed in the Relocated column.

Oracle recommends that you do not use constants in their DBMS_XDB context in new applications. Support for deprecated features is for backward compatibility only and may be terminated in future releases.

This procedure is deprecated in Release 12c. This functionality is replaced by a subprogram of the same name in the DBMS_XDB_REPOS package - the APPENDRESOURCEMETADATA Procedure.

This procedure takes in user-defined metadata either as a REF to XMLTYPE or an XMLTYPE and adds it to the desired resource.

Syntax

DBMS_XDB.APPENDRESOURCEMETADATA (
 abspath   IN  VARCHAR2, 
 metadata  IN  XMLTYPE);

DBMS_XDB.APPENDRESOURCEMETADATA (
 abspath   IN  VARCHAR2,

Parameters

Table 181-12 APPENDRESOURCEMETADATA Procedure

Parameter	Description
`abspath`	Absolute path of the resource
`metadata`	Metadata can be schema based or nonschema-based. Schema-based metadata is stored in its own table.

Usage Notes

In the case in which a REF is passed in, the procedure stores the REF in the resource, and the metadata is stored in a separate table. In this case you are responsible for populating the RESID column for the metadata table. Note that theREF passed in must be unique. In other words, there must not be aREF with the same value in the resource metadata, as this would violate uniqueness of properties. An error is thrown if users attempt to add a REF that already exists.
In the case where the XMLTYPE is passed in, the data is parsed to determine if it is schema-based or not and stored accordingly.

Table 181-19 CREATERESOURCE Function Parameters

Parameter	Description
`abspath`	Absolute path of the resource to create. The path name's parent folder must already exist in the hierarchy. In other words, if `/foo/bar.txt` is passed in, then folder `/foo` must already exist.
`data`	String buffer containing new resource's contents. The data is parsed to check if it contains a schema-based XML document, and the contents are stored as schema-based in the schema's default table. Otherwise, it is saved as binary data.
`datarow`	`REF` to an `XMLType` row to be used as the contents
`csid`	Character set id of the document. Must be a valid Oracle ID; otherwise returns an error. If CSID is not specified, or if a zero CSID is specified, then the character set id of the document is determined as follows: From the abspath extension, determine the resource's MIME type. If the MIME type is */xml, then the encoding is detected based on Appendix F of the W3C XML 1.0 Reference at `http://www.w3.org/TR/2000/REC-xml-20001006`; Otherwise, it is defaulted to the database character set.
`createfolders`	If `TRUE`, create the parent folders if they do not exist
`schemaurl`	For XML data, schema URL data conforms to (default `NULL`)
`elem`	Element name (default `NULL`)

Return Values

TRUE if operation successful; FALSE, otherwise.

Note:

This procedure is deprecated in Release 12c. This functionality is replaced by a subprogram of the same name in the DBMS_XDB_REPOS package - the UPDATERESOURCEMETADATA Procedures.

This procedure updates metadata for a resource. The procedure takes in a resource identified by absolute path and the metadata in it to replace identified by its REF. It replaces that piece of metadata with user-defined metadata which is either in the form of a REF to XMLTYPE or an XMLTYPE.

Syntax

Can be used to update schema-based metadata only. The new metadata must be schema-based:

DBMS_XDB.UPDATERESOURCEMETADATA(
   abspath  IN VARCHAR2,
   oldmetadata    IN   REF SYS.XMLTYPE,
   newmetadata    IN   REF SYS.XMLTYPE)

Can be used to update schema-based metadata only. The new metadata must be schema-based or nonschema-based:

DBMS_XDB.UPDATERESOURCEMETADATA(
   abspath        IN   VARCHAR2,
   oldmetadata    IN   REF SYS.XMLTYPE,
   newmetadata    IN   XMLTYPE);

Can be used for both schema-based and nonschema-based metadata:

DBMS_XDB.UPDATERESOURCEMETADATA(
   abspath        IN   VARCHAR2,
   oldns          IN   VARCHAR2,
   oldname IN VARCHAR,
   newmetadata IN XMLTYPE);

Can be used for both schema-based or nonschema-based metadata. New metadata must be schema-based:

DBMS_XDB.UPDATERESOURCEMETADATA(
   abspath       IN   VARCHAR2,
   oldns         IN   VARCHAR2,
   oldname       IN   VARCHAR,
   newmetadata   IN   REF SYS.XMLTYPE);

Parameters

Table 181-59 UPDATERESOURCEMETADATA Procedure Parameters

Parameter	Description
`abspath`	Absolute path of the resource
`oldmetadata`	`REF` to the old of metadata
`newmetadata`	`REF` to the new, replacement metadata (can be either schema-based or nonschema-based depending on the overload)
`oldns`	Namespace identifying old metadata
`oldname`	Local name identifying old metadata

Usage Notes

In the case of REF, it stores the REF in the resource and the metadata is stored in a separate table. Uniqueness of REFs is enforced. In the case where the XMLTYPE is passed in, data is parsed to determine if it is schema-based or not and is stored accordingly.
