ADDREPOSITORYRESCONFIG Procedure

This procedure inserts the resource configuration specified by absolute path of the resource configuration at the specified position of the repository's configuration list. It shifts the element currently at that position (if any) and any subsequent elements to the right.

Syntax

DBMS_RESCONFIG.ADDREPOSITORYRESCONFIG(
   rcpath     IN   VARCHAR2, 
   pos        IN   PLS_INTEGER := NULL); 

Parameters

Table 115-2 ADDREPOSITORYRESCONFIG Function Parameters

Parameter Description

rcpath

Absolute path of the resource configuration to be inserted. An exception is raised if rcpath already exists in the target's configuration list.

pos

Index at which the new configuration is to be inserted. If this parameter is not specified then the new configuration is appended to the end of the list. An exception is raised if the index is out of range (pos < 0 or pos > the size of the target resource's configuration list).


Usage Notes


ADDRESCONFIG Procedure

This procedure inserts the resource configuration specified by the absolute path of the resource configuration at the given position in the target resource's configuration list. It shifts the element currently at that position (if any) and any subsequent elements to the right.

Syntax

DBMS_RESCONFIG.ADDRESCONFIG(
   respath    IN   VARCHAR2, 
   rcpath     IN   VARCHAR2, 
   pos        IN   PLS_INTEGER := NULL); 

Parameters

Table 115-3 ADDRESCONFIG Function Parameters

Parameter Description

respath

Absolute path of the target resource

rcpath

Absolute path of the resource configuration to be inserted. An exception is raised if rcpath already exists in the target's configuration list.

pos

Index at which the new configuration is to be inserted. If this parameter is not specified then the new configuration is appended to the end of the list. An exception is raised if the index is out of range (pos < 0 or pos > the size of the target resource's configuration list).


Usage Notes


APPENDRESCONFIG Procedure

This procedure appends the resource configuration specified by rcpath to the target resource's configuration list if it is not already included in the list.

Syntax

DBMS_RESCONFIG.ADDRESCONFIG(
   respath       IN   VARCHAR2, 
   rcpath        IN   VARCHAR2, 
   appendOption  IN   PLS_INTEGER); 

Parameters

Table 115-4 ADDRESCONFIG Function Parameters

Parameter Description

respath

Absolute path of the target resource

rcpath

Absolute path of the resource configuration to be appended at the end of the target's configuration list. If rcpath already exists in the list then nothing is appended.

appendOption

Either APPEND_RESOURCE or APPEND_RECURSIVE. If APPEND_RESOURCE is specified then only the target resource is affected. If APPEND_RECURSIVE is specified then the target resource and all its descendents will be affected.


Usage Notes


DELETEREPOSITORYRESCONFIG Procedure

This procedure removes the configuration at the given position in the repository's configuration list. It shifts any subsequent elements to the left.

Syntax

DBMS_RESCONFIG.DELETEREPOSITORYRESCONFIG(
   pos           IN   PLS_INTEGER);

Parameters

Table 115-5 DELETEREPOSITORYRESCONFIG Function Parameters

Parameter Description

pos

The index of the configuration to be removed. An exception is raised if the index is out of range (pos < 0 or pos >= the size of the target resource's configuration list).


Usage Notes


DELETERESCONFIG Procedures

This procedure removes the configuration at the given position in the target resource's configuration list. It shifts any subsequent elements to the left. Users can use the overloaded for recursive deletion.

Syntax

DBMS_RESCONFIG.DELETERESCONFIG(
   respath       IN   VARCHAR2, 
   pos           IN   PLS_INTEGER);
DBMS_RESCONFIG.DELETERESCONFIG(
   respath        IN  VARCHAR2,
   rcpath         IN  VARCHAR2, 
   deleteOption   IN  PLS_INTEGER);

Parameters

Table 115-6 DELETERESCONFIG Procedure Parameters

Parameter Description

respath

Absolute path of the target resource

pos

The index of the configuration to be removed. An exception is raised if the index is out of range (pos < 0 or pos >= the size of the target resource's configuration list).

rcpath

Absolute path of the resource configuration to be deleted if found in list.

deleteOption

Either DELETE_RESOURCE or DELETE_RECURSIVE. If DELETE_RESOURCE is specified then only the configuration list of the target resource is affected. If DELETE_RECURSIVE is specified then the configuration list of the target resource and all its descendents will be affected.


Usage Notes

Users must have WRITE-CONFIG privilege on the target resource to execute this.


GETLISTENERS Function

This function returns the list of listeners applicable for a given resource.

The value returned by this function is an XML document containing the <event-listeners> element of the XDBResconfig.xsd schema. It contains all the listeners applicable to the target resource, including repository-level listeners. From the returned XML document users can use the EXTRACT operator to retrieve the listeners defined for a specific event.

Syntax

DBMS_RESCONFIG.GETLISTENERS(
   path    IN   VARCHAR2)
 RETURN XMLTYPE; 

Parameters

Table 115-7 GETLISTENERS Function Parameters

Parameter Description

path

Absolute path of the target resource


Usage Notes

Users must have the required access privilege on all resource configurations referenced by the repository and the target resource; otherwise, an error is returned.


GETREPOSITORYRESCONFIG Function

This function returns the resource configuration at the specified position of the repository's configuration list.

Syntax

DBMS_RESCONFIG.GETREPOSITORYRESCONFIG(
   pos    IN   PLS_INTEGER)
 RETURN XMLTYPE; 

Parameters

Table 115-8 GETREPOSITORYRESCONFIG Function Parameters

Parameter Description

pos

Index of element to return. An exception is raised if the index is out of range (pos < 0 or pos >= the size of the repository's configuration list).


Usage Notes

Users must have the required read privilege on the requested resource configuration; otherwise, an error is returned.


GETREPOSITORYRESCONFIGPATHS Function

This function returns a list of resource configuration paths defined for the repository.

Syntax

DBMS_RESCONFIG.GETREPOSITORYRESCONFIGPATHS
 RETURN XDB$STRING_LIST_T; 

Usage Notes

Users must be able to access all the referenced resource configurations; otherwise, an error is returned.


GETRESCONFIG Function

This function returns the resource configuration at the specified position of the target resource's configuration list.

Syntax

DBMS_RESCONFIG.GETRESCONFIG(
   respath IN VARCHAR2,  
   pos IN PLS_INTEGER)
 RETURN XMLTYPE; 

Parameters

Table 115-9 GETRESCONFIG Function Parameters

Parameter Description

respath

Absolute path of the target resource

pos

Index of element to return. An exception is raised if the index is out of range (pos < 0 or pos >= the size of the target resource's configuration list).


Usage Notes

Users must have the required read privilege on the requested resource configuration; otherwise, an error is returned.


GETRESCONFIGPATHS Function

This function returns a list of resource configuration paths defined in the target resource's configuration list.

Syntax

DBMS_RESCONFIG.GETRESCONFIGPATHS(
   respath IN VARCHAR2)  
 RETURN XDB$STRING_LIST_T; 

Parameters

Table 115-10 GETRESCONFIGPATHS Function Parameters

Parameter Description

respath

Absolute path of the target resource


Usage Notes

Users must be able to access all the referenced resource configurations; otherwise, an error is returned.


PATCHREPOSITORYRESCONFIGLIST Procedure

Under normal circumstances, deletion of a resource configuration resource cannot be performed if it is part of the repository resource configuration list. If, for some reason, the deletion of a resource configuration resource that is part of the repository resource configuration list succeeds, then any repository operation results in a 'dangling reference' error. This procedure removes invalid references from the repository resource configuration list, and makes the repository available. This procedure must be run as SYS.

Syntax

DBMS_RESCONFIG.PATCHREPOSITORYRESCONFIGLIST;
