This procedure allows the DBA to alter existing deployment templates. Alterations can include defining a new deployment template name, a new refresh group, or a new owner and changing the public/private status.

Syntax

DBMS_REPCAT_RGT.ALTER_REFRESH_TEMPLATE (
   refresh_template_name      IN   VARCHAR2,
   new_owner                  IN   VARCHAR2 := '-',
   new_refresh_group_name     IN   VARCHAR2 := '-',
   new_refresh_template_name  IN   VARCHAR2 := '-',
   new_template_comment       IN   VARCHAR2 := '-',
   new_public_template        IN   VARCHAR2 := '-',
   new_last_modified          IN   DATE := to_date('1', 'J'),
   new_modified_by            IN   NUMBER := -1e-130);

Parameters

Table 21-2 ALTER_REFRESH_TEMPLATE Procedure Parameters

Parameter	Description
refresh_template_name	The name of the deployment template that you want to alter.
new_owner	The name of the new deployment template owner. Do not specify a value to keep the current owner.

new_refresh_template_name	Use this parameter to specify a new deployment template name. Do not specify a value to keep the current deployment template name.
new_template_comment	New deployment template comments. Do not specify a value to keep the current template comment.
new_public_template	Determines whether the deployment template is public or private. Only acceptable values are `'Y'` and `'N'` (`'Y'` = public and `'N'` = private). Do not specify a value to keep the current value.
new_last_modified	Contains the date of the last modification made to this deployment template. If a value is not specified, then the current date is automatically used.
new_modified_by	Contains the name of the user who last modified this deployment template. If a value is not specified, then the current user is automatically used.

Exceptions

Table 21-3 ALTER_REFRESH_TEMPLATE Procedure Exceptions

Exception	Description
miss_refresh_template	Deployment template name specified is invalid or does not exist.
bad_public_template	The `public_template` parameter is specified incorrectly. The `public_template` parameter must be specified as a `'Y'` for a public template or an `'N'` for a private template.
dupl_refresh_template	A template with the specified name already exists. See the ALL_REPCAT_REFRESH_TEMPLATES view.

ALTER_TEMPLATE_OBJECT Procedure

This procedure alters objects that have been added to a specified deployment template. The most common changes are altering the object DDL and assigning the object to a different deployment template.

Changes made to the template are reflected only at new sites instantiating the deployment template. Remote sites that have already instantiated the template must reinstantiate the deployment template to apply the changes.

Syntax

DBMS_REPCAT_RGT.ALTER_TEMPLATE_OBJECT (
   refresh_template_name       IN   VARCHAR2, 
   object_name                 IN   VARCHAR2,
   object_type                 IN   VARCHAR2,
   new_refresh_template_name   IN   VARCHAR2 := '-',
   new_object_name             IN   VARCHAR2 := '-',
   new_object_type             IN   VARCHAR2 := '-',
   new_ddl_text                IN   CLOB     := '-',
   new_master_rollback_seg     IN   VARCHAR2 := '-',
   new_flavor_id               IN   NUMBER   := -1e-130);

Usage Notes

Because the ALTER_TEMPLATE_OBJECT procedure utilizes a CLOB, you must use the DBMS_LOB package when using the ALTER_TEMPLATE_OBJECT procedure. The following example illustrates how to use the DBMS_LOB package with the ALTER_TEMPLATE_OBJECT procedure:

DECLARE
   tempstring VARCHAR2(100);
   templob CLOB;
BEGIN
   DBMS_LOB.CREATETEMPORARY(templob, TRUE, DBMS_LOB.SESSION);
   tempstring := 'CREATE MATERIALIZED VIEW mview_sales AS SELECT *
      FROM sales WHERE salesperson = :salesid and region_id = :region';
   DBMS_LOB.WRITE(templob, length(tempstring), 1, tempstring);
   DBMS_REPCAT_RGT.ALTER_TEMPLATE_OBJECT(
      refresh_template_name => 'rgt_personnel',
      object_name => 'MVIEW_SALES',
      object_type => 'MATERIALIZED VIEW',
      new_ddl_text => templob);
   DBMS_LOB.FREETEMPORARY(templob);
END;
/

ALTER_TEMPLATE_PARM Procedure

This procedure allows the DBA to alter the parameters for a specific deployment template. Alterations include renaming the parameter and redefining the default value and prompt string.

Syntax

DBMS_REPCAT_RGT.ALTER_TEMPLATE_PARM (
   refresh_template_name       IN   VARCHAR2,
   parameter_name              IN   VARCHAR2,
   new_refresh_template_name   IN   VARCHAR2 := '-',
   new_parameter_name          IN   VARCHAR2 := '-',
   new_default_parm_value      IN   CLOB := NULL,
   new_prompt_string           IN   VARCHAR2 := '-',
   new_user_override           IN   VARCHAR2 := '-');

Parameters

Table 21-6 ALTER_TEMPLATE_PARM Procedure Parameters

Parameter	Description
refresh_template_name	Name of the deployment template that contains the parameter that you want to alter.
parameter_name	Name of the parameter that you want to alter.
new_refresh_template_name	Name of the deployment template that the specified parameter should be reassigned to (useful when you want to move a parameter from one template to another). Do not specify a value to keep the parameter assigned to the current template.
new_parameter_name	New name of the template parameter. Do not specify a value to keep the current parameter name.
new_default_parm_value	New default value for the specified parameter. Do not specify a value to keep the current default value.
new_prompt_string	New prompt text for the specified parameter. Do not specify a value to keep the current prompt string.
new_user_override	Determines whether the user can override the default value if prompted during the instantiation process. The user is prompted if no user parameter value has been defined for this parameter. Set this parameter to `'Y'` to allow a user to override the default value or set this parameter to `'N'` to prevent an override.

Exceptions

Table 21-7 ALTER_TEMPLATE_PARM Procedure Exceptions

Exception	Description
miss_refresh_template	Deployment template name specified is invalid or does not exist.
miss_template_parm	Template parameter specified is invalid or does not exist.
dupl_template_parm	Combination of `new_refresh_template_name` and `new_parameter_name` already exists.

Usage Notes

Because the ALTER_TEMPLATE_PARM procedure utilizes a CLOB, you must use the DBMS_LOB package when using the ALTER_TEMPLATE_PARM procedure. The following example illustrates how to use the DBMS_LOB package with the ALTER_TEMPLATE_PARM procedure:

DECLARE
   tempstring VARCHAR2(100);
   templob CLOB;
BEGIN
   DBMS_LOB.CREATETEMPORARY(templob, TRUE, DBMS_LOB.SESSION);
   tempstring := 'REGION 20';
   DBMS_LOB.WRITE(templob, length(tempstring), 1, tempstring);
   DBMS_REPCAT_RGT.ALTER_TEMPLATE_PARM(
      refresh_template_name => 'rgt_personnel',
      parameter_name => 'region',
      new_default_parm_value => templob);
   DBMS_LOB.FREETEMPORARY(templob);
END;
/

ALTER_USER_AUTHORIZATION Procedure

This procedure alters the contents of the DBA_REPCAT_USER_AUTHORIZATIONS view. Specifically, you can change user/deployment template authorization assignments. This procedure is helpful, for example, if an employee is reassigned and requires the materialized view environment of another deployment template. The DBA simply assigns the employee the new deployment template and the user is authorized to instantiate the target template.

Syntax

DBMS_REPCAT_RGT.ALTER_USER_AUTHORIZATION (
   user_name                   IN   VARCHAR2,
   refresh_template_name       IN   VARCHAR2,
   new_user_name               IN   VARCHAR2 := '-',
   new_refresh_template_name   IN   VARCHAR2 := '-');

Parameters

Table 21-8 ALTER_USER_AUTHORIZATION Procedure Parameters

Parameter	Description
user_name	Name of the user whose authorization you want to alter.
refresh_template_name	Name of the deployment template that is currently assigned to the specified user that you want to alter.
new_user_name	Use this parameter to define a new user for this template authorization. Do not specify a value to keep the current user.
new_refresh_template_name	The deployment template that the specified user (either the existing or, if specified, the new user) is authorized to instantiate. Do not specify a value to keep the current deployment template.

Exceptions

Table 21-9 ALTER_USER_AUTHORIZATION Procedure Exceptions

Exception	Description
miss_user_authorization	The combination of `user_name` and `refresh_template_name` values specified does not exist in the `DBA_REPCAT_USER_AUTHORIZATIONS` view.
miss_user	The user name specified for the `new_user_name` or `user_name` parameter is invalid or does not exist.
miss_refresh_template	The deployment template specified for the `new_refresh_template` parameter is invalid or does not exist.
dupl_user_authorization	A row already exists for the specified user name and deployment template name. See the ALL_REPCAT_USER_AUTHORIZATIONS view.

ALTER_USER_PARM_VALUE Procedure

This procedure changes existing parameter values that have been defined for a specific user. This procedure is especially helpful if your materialized view environment uses assignment tables. Change a user parameter value to quickly and securely change the data set of a remote materialized view site.

Parameter	Description
refresh_template_name	Name of the deployment template that contains the user parameter value that you want to alter.
parameter_name	Name of the parameter that you want to alter.
user_name	Name of the user whose parameter value you want to alter.
new_refresh_template_name	Name of the deployment template that the specified user parameter value should be reassigned to (useful when you are authorizing a user for a different template). Do not specify a value to keep the parameter assigned to the current template.
new_parameter_name	The new template parameter name. Do not specify a value to keep the user value defined for the existing parameter.
new_user_name	The new user name that this parameter value is for. Do not specify a value to keep the parameter value assigned to the current user.
new_parm_value	The new parameter value for the specified user parameter. Do not specify a value to keep the current parameter value.

COMPARE_TEMPLATES Function

This function allows a DBA to compare the contents of two deployment templates. Any discrepancies between the two deployment templates is stored in the USER_REPCAT_TEMP_OUTPUT temporary view.

The COMPARE_TEMPLATES function returns a number that you specify in the WHERE clause when querying the USER_REPCAT_TEMP_OUTPUT temporary view. For example, if the COMPARE_TEMPLATES procedure returns the number 10, you would execute the following SELECT statement to view all discrepancies between two specified templates (your SELECT statement returns no rows if the templates are identical):

SELECT TEXT FROM USER_REPCAT_TEMP_OUTPUT
   WHERE OUTPUT_ID =  10 ORDER BY LINE;

The contents of the USER_REPCAT_TEMP_OUTPUT temporary view are lost after you disconnect or a rollback has been performed.

Syntax

DBMS_REPCAT_RGT.COMPARE_TEMPLATES (
   source_template_name    IN   VARCHAR2,
   compare_template_name   IN   VARCHAR2)
  RETURN NUMBER;

Parameters

Table 21-12 COMPARE_TEMPLATES Function Parameters

Returns

Table 21-14 COMPARE_TEMPLATES Function Returns

Return Value	Description
<system-generated number>	Specifies the number returned for the `output_id` value when you select from the `USER_REPCAT_TEMP_OUTPUT` temporary view to view the discrepancies between the compared templates.

COPY_TEMPLATE Function

This function enables you to copy a deployment template and is helpful when a new deployment template uses many of the objects contained in an existing deployment template. This function copies the deployment template, template objects, template parameters, and user parameter values. The DBA can optionally have the function copy the user authorizations for this template. The number returned by this function is used internally by Oracle to manage deployment templates.

Note:

The values in the DBA_REPCAT_TEMPLATE_SITES view are not copied.

This function also allows the DBA to copy a deployment template to another master site, which is helpful for deployment template distribution and to split network loads between multiple sites.

Syntax

DBMS_REPCAT_RGT.COPY_TEMPLATE (
   old_refresh_template_name     IN   VARCHAR2, 
   new_refresh_template_name     IN   VARCHAR2,
   copy_user_authorizations      IN   VARCHAR2,
   dblink                        IN   VARCHAR2 := NULL)
  RETURN NUMBER;

Returns

Table 21-17 COPY_TEMPLATES Function Returns

Return Value	Description
<system-generated number>	System-generated number used internally by Oracle.

CREATE_OBJECT_FROM_EXISTING Function

This function creates a template object definition from existing database objects and adds it to a target deployment template. The object DDL that created the original database object is executed when the target deployment template is instantiated at the remote materialized view site. This is ideal for adding existing triggers and procedures to your template. The number returned by this function is used internally by Oracle to manage deployment templates.

Syntax

DBMS_REPCAT_RGT.CREATE_OBJECT_FROM_EXISTING(
     refresh_template_name  IN   VARCHAR2,
     object_name            IN   VARCHAR2,

Usage Notes

Because CREATE_TEMPLATE_OBJECT utilizes a CLOB, you must use the DBMS_LOB package when using the CREATE_TEMPLATE_OBJECT function. The following example illustrates how to use the DBMS_LOB package with the CREATE_TEMPLATE_OBJECT function:

DECLARE
   tempstring VARCHAR2(100);
   templob CLOB;
   a NUMBER;
BEGIN
   DBMS_LOB.CREATETEMPORARY(templob, TRUE, DBMS_LOB.SESSION);
   tempstring := 'CREATE MATERIALIZED VIEW mview_sales AS SELECT *
        FROM sales WHERE salesperson = :salesid';
   DBMS_LOB.WRITE(templob, length(tempstring), 1, tempstring);
   a := DBMS_REPCAT_RGT.CREATE_TEMPLATE_OBJECT(
        refresh_template_name => 'rgt_personnel',
        object_name => 'mview_sales',
        object_type => 'MATERIALIZED VIEW',
        ddl_text => templob,
        master_rollback_seg => 'RBS');
   DBMS_LOB.FREETEMPORARY(templob);
END;
/

CREATE_TEMPLATE_PARM Function

This function creates parameters for a specific deployment template to allow custom data sets to be created at the remote materialized view site. This function is only required when the DBA wants to define a set of template variables before adding any template objects. When objects are added to the template using the CREATE_TEMPLATE_OBJECT function, any variables in the object DDL are automatically added to the DBA_REPCAT_TEMPLATE_PARMS view.

The DBA typically uses the ALTER_TEMPLATE_PARM function to modify the default parameter values or prompt strings or both (see "ALTER_TEMPLATE_PARM Procedure" for more information). The number returned by this function is used internally by Oracle to manage deployment templates.

Syntax

DBMS_REPCAT_RGT.CREATE_TEMPLATE_PARM (
   refresh_template_name  IN   VARCHAR2, 
   parameter_name         IN   VARCHAR2,
   default_parm_value     IN   CLOB := NULL,
   prompt_string          IN   VARCHAR2 := NULL,
   user_override          IN   VARCHAR2 := NULL)
 RETURN NUMBER;

Parameters

Usage Notes

Because the CREATE_TEMPLATE_PARM function utilizes a CLOB, you must use the DBMS_LOB package when using the CREATE_TEMPLATE_PARM function. The following example illustrates how to use the DBMS_LOB package with the CREATE_TEMPLATE_PARM function:

DECLARE
   tempstring VARCHAR2(100);
   templob CLOB;
   a NUMBER;
BEGIN
   DBMS_LOB.CREATETEMPORARY(templob, TRUE, DBMS_LOB.SESSION);
   tempstring := 'REGION 20';
   DBMS_LOB.WRITE(templob, length(tempstring), 1, tempstring);
   a := DBMS_REPCAT_RGT.CREATE_TEMPLATE_PARM(
        refresh_template_name => 'rgt_personnel',
        parameter_name => 'region',
        default_parm_value => templob,
        prompt_string => 'Enter your region ID:',
        user_override => 'Y');
   DBMS_LOB.FREETEMPORARY(templob);
END;

GET_RUNTIME_PARM_ID Function

This function retrieves an identification to be used when defining a run-time parameter value. All run-time parameter values are assigned to this identification and are also used during the instantiation process.

Syntax

DBMS_REPCAT_RGT.GET_RUNTIME_PARM_ID
  RETURN NUMBER;

Parameters

None

Returns

Table 21-60 GET_RUNTIME_PARM_ID Function Returns

Return Value	Corresponding Data Type
<system-generated number>	Runtime parameter values are assigned to the system-generated number and are also used during the instantiation process.

INSERT_RUNTIME_PARMS Procedure

This procedure defines run-time parameter values prior to instantiating a template. This procedure should be used to define parameter values when no user parameter values have been defined and you do not want to accept the default parameter values.

Before using the this procedure, be sure to execute the GET_RUNTIME_PARM_ID function to retrieve a parameter identification to use when inserting a run-time parameter. This identification is used for defining run-time parameter values and instantiating deployment templates.

Syntax

DBMS_REPCAT_RGT.INSERT_RUNTIME_PARMS (
   runtime_parm_id    IN   NUMBER, 
   parameter_name     IN   VARCHAR2,
   parameter_value    IN   CLOB);

Parameters

Table 21-61 INSERT_RUNTIME_PARMS Procedure Parameters

Parameter	Description
runtime_parm_id	The identification retrieved by the `GET_RUNTIME_PARM_ID` function. This identification is also used when instantiating the deployment template. Be sure to use the same identification for all parameter values for a deployment template.
parameter_name	Name of the template parameter for which you are defining a run-time parameter value. Query the `DBA_REPCAT_TEMPLATE_PARMS` view for a list of template parameters.
parameter_value	The run-time parameter value that you want to use during the deployment template instantiation process.

Table 21-62 INSERT_RUNTIME_PARMS Procedure Exceptions

Exception	Description
`miss_refresh_template`	The deployment template name specified is invalid or does not exist.
`miss_user`	The user name specified is invalid or does not exist.
`miss_user_parm_values`	The deployment template, user, and parameter combination does not exist in the `DBA_REPCAT_USER_PARM_VALUES` view.

Usage Notes

Because the this procedure utilizes a CLOB, you must use the DBMS_LOB package when using the INSERT_RUNTIME_PARMS procedure. The following example illustrates how to use the DBMS_LOB package with the INSERT_RUNTIME_PARMS procedure:

DECLARE
   tempstring VARCHAR2(100);
   templob CLOB;
BEGIN
   DBMS_LOB.CREATETEMPORARY(templob, TRUE, DBMS_LOB.SESSION);
   tempstring := 'REGION 20';
   DBMS_LOB.WRITE(templob, length(tempstring), 1, tempstring);
   DBMS_REPCAT_RGT.INSERT_RUNTIME_PARMS(
      runtime_parm_id => 20,
      parameter_name => 'region',
      parameter_value => templob);
   DBMS_LOB.FREETEMPORARY(templob);
END;
/

INSTANTIATE_OFFLINE Function

This function generates a script at the master site that is used to create the materialized view environment at the remote materialized view site while the materialized view site disconnected from the master (that is, while the materialized view site is offline). This generated script should be used at remote materialized view sites that are not able to remain connected to the master site for an extended amount of time, as the instantiation process at the remote materialized view site might be lengthy (depending on the amount of data that is populated to the new materialized views). This function must be executed separately for each user instantiation.

The script generated by this function is stored in the USER_REPCAT_TEMP_OUTPUT temporary view and is used by several Oracle tools, including the Advanced Replication interface in Oracle Enterprise Manager, during the distribution of deployment templates. The number returned by this function is used to retrieve the appropriate information from the USER_REPCAT_TEMP_OUTPUT temporary view.

Note:

This function is used to perform an offline instantiation of a deployment template. Additionally, this function is for replication administrators who are instantiating for another user. Users wanting to perform their own instantiation should use the public version of the INSTANTIATE_OFFLINE function. See the "INSTANTIATE_OFFLINE Function" for more information.

This function should not be confused with the procedures in the DBMS_OFFLINE_OG package (used for performing an offline instantiation of a master table). See the documentation for this package for more information about their usage.

LOCK_TEMPLATE_EXCLUSIVE Procedure

When a deployment template is being updated or modified, you should use the LOCK_TEMPLATE_EXCLUSIVE procedure to prevent users from reading or instantiating the template.

The lock is released when a ROLLBACK or COMMIT is performed.

Note:

This procedure should be executed before you make any modifications to your deployment template.

Syntax

DBMS_REPCAT_RGT.LOCK_TEMPLATE_EXCLUSIVE();

Parameters

None

LOCK_TEMPLATE_SHARED Procedure

The LOCK_TEMPLATE_SHARED procedure is used to make a specified deployment template "read-only." This procedure should be called before instantiating a template, as this ensures that nobody can change the deployment template while it is being instantiated.

The lock is released when a ROLLBACK or COMMIT is performed.

Syntax

DBMS_REPCAT_RGT.LOCK_TEMPLATE_SHARED();

Parameters

None
