INSTANTIATE_OFFLINE Function

This function generates a file at the master site that is used to create the materialized view environment at the remote materialized view site while offline. This generated file is an offline instantiation file and 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.

This is an ideal solution when the remote materialized view site is a laptop. Use the packaging interface in the Replication Management tool to package the generated file and data into a single file that can be posted on an FTP site or loaded to a CD-ROM, floppy disk, and so on. You can also transfer the file using the DBMS_FILE_TRANSFER package.

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 Replication Management tool, 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 view.

The user who executes this public function becomes the "registered" user of the instantiated template at the specified site.

Note: This function is used in performing an offline instantiation of a deployment template. 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 on their usage.

Parameters

Table 20-3 INSTANTIATE_OFFLINE Function Parameters

Parameter	Description
refresh_template_name	The name of the deployment template to be instantiated.
site_name	The name of the remote site that is instantiating the deployment template.
runtime_parm_id	If you have defined runtime parameter values using the INSERT_RUNTIME_PARMS procedure, specify the identification used when creating the runtime parameters (the identification was retrieved by using the GET_RUNTIME_PARM_ID function).
next_date	The next refresh date value to be used when creating the refresh group.
interval	The refresh interval to be used when creating the refresh group.
use_default_gowner	If true, then any materialized view groups created are owned by the default user PUBLIC. If false, then any materialized view groups created are owned by the user performing the instantiation.

Exceptions

Table 20-4 INSTANTIATE_OFFLINE Function Exceptions

Exception	Description
miss_refresh_template	The deployment template name specified is invalid or does not exist.
dupl_template_site	The deployment template has already been instantiated at the materialized view site. A deployment template can be instantiated only once at a particular materialized view site.
not_authorized	The user attempting to instantiate the deployment template is not authorized to do so.

Returns

Table 20-5 INSTANTIATE_OFFLINE Function Returns

Return Value	Description
<system-generated number>	Specifies the generated system number for the output_id when you select from the USER_REPCAT_TEMP_OUTPUT view to retrieve the generated instantiation script.
