41 DBMS_CSX_ADMIN

The DBMS_CSX_ADMIN package provides an interface to customize the setup when transporting a tablespace containing binary XML data.

The chapter contains the following topics:


Using DBMS_CSX_ADMIN


Overview

This package can be used by DBAs to customize the setup when transporting a tablespace containing binary XML data. The use of the package is not required in order for a transportable tablespace job to run.

By default, all binary XML tables will use the default token table set, which will be replicated during transport on the target database. To avoid the cost of transporting a potentially large token table set, the DBA may opt for registering a new set of token tables for a given tablespace. The package provides routines for token table set registration and lookup.


Security Model

Owned by XDB, the DBMS_CSX_ADMIN package must be created by SYS or XDB. The EXECUTE privilege is granted to SYS or XDB or DBA. Subprograms in this package are executed using the privileges of the current user.


Constants

The DBMS_CSX_ADMIN package uses the constants shown in Table 41-1:

Token table set associated with tables, not tablespaces

TBS_LEVEL

BINARY_INTEGER

2

Token table set associated with a tablespace

NO_CREATE

BINARY_INTEGER

0

Token tables already exist, associate them with the given table/tablespace

NO_INDEXES

1

Do not create indexes on the new set of token tables

WITH_INDEXES

BINARY_INTEGER

2

Summary of DBMS_CSX_ADMIN

Table 41-2 DBMS_CSX_ADMIN Package Subprograms

Subprogram Description

GETTOKENTABLEINFO Procedure & Function

Returns the GUID of the token table set where token mappings for this table

GETTOKENTABLEINFOBYTABLESPACE Procedure

Returns the GUID and the token table names for this tablespace

NAMESPACEIDTABLE Function

Returns default namespace-ID token table

PATHIDTABLE Function

Returns the default path-ID token table

QNAMEIDTABLE Function

Returns the default qname-ID token table.



GETTOKENTABLEINFO Procedure & Function

Given the table name and the owner, the first overload of the procedure returns the globally unique identifier (GUID) of the token table set where token mappings for this table can be found. The procedure returns also the names of the token tables, and whether the token table set is the default one.

Given the object number of a table, the second overload of the procedure returns the GUID of the token table set used by the table, and whether this is the default token table set.

Syntax

DBMS_CSX_ADMIN.GETTOKENTABLEINFO  (
   ownername      IN   VARCHAR2,
   tablename      IN   VARCHAR2,
   guid           OUT  RAW,
   qnametable     OUT  VARCHAR2,
   nmspctable     OUT  VARCHAR2,
   level          OUT  NUMBER,
   tabno          OUT  NUMBER);
DBMS_CSX_ADMIN.GETTOKENTABLEINFO  (
   tabno          IN   NUMBER,
   guid           OUT  RAW);
 RETURN BOOLEAN;

Parameters

Table 41-3 GETTOKENTABLEINFO Procedure & Function Parameters

Parameter Description

ownername

Owner of the table

tablename

Name of the table

guid

GUID of the token table set used by the given table

qnametable

Name of the qname-ID table in the new set

nmspctable

Name of the namespace-ID table in the new set

level

DEFAULT_LEVEL if default token table set, TBS_LEVEL if same token table set is used by all tables in the same tablespace as the given table, TAB_LEVEL otherwise

tabno

Table object number



GETTOKENTABLEINFOBYTABLESPACE Procedure

Given a tablespace number, this procedure returns the GUID and the token table names for this tablespace.

Syntax

DBMS_CSX_ADMIN.GETTOKENTABLEINFOBYTABLESPACE  (
   tsname          IN   VARCHAR2,
   tablespaceno    IN   NUMBER,
   guid            OUT  RAW,
   qnametable      OUT  VARCHAR2,
   nmspctable      OUT  VARCHAR2,
   isdefault       OUT  BOOLEAN,
   containTokTab   OUT  BOOLEAN);

Parameters

Table 41-4 GETTOKENTABLEINFOBYTABLESPACE Procedure Parameters

Parameter Description

tsname

Tablespace name

tablespaceno

Tablespace number

guid

GUID of the token table set associated with this tablespace (if any)

qnametable

Name of the qname-ID table

nmspctable

Name of the namespace-ID table

isdefault

TRUE if the token table is the default one

containTokTab

TRUE if the tablespace contains its own token table set



NAMESPACEIDTABLE Function

This procedure returns default namespace-ID token table.

Syntax

DBMS_CSX_ADMIN.NAMESPACEIDTABLE 
  RETURN VARCHAR2;

PATHIDTABLE Function

This procedure returns the default path-ID token table. This is used for granting permissions on the default path-ID token table for a user before executing EXPLAIN PLAN for a query on an XML table with an XML index.

Syntax

DBMS_CSX_ADMIN.PATHIDTABLE 
  RETURN VARCHAR2;

QNAMEIDTABLE Function

This procedure returns the default qname-ID token table.

Syntax

DBMS_CSX_ADMIN.QNAMEIDTABLE 
  RETURN VARCHAR2;
