Summary of DBMS_OFFLINE_SNAPSHOT Subprograms

Table 37-1 DBMS_OFFLINE_SNAPSHOT Package Subprograms

Subprogram	Description
BEGIN_LOAD Procedure	Prepares a materialized view site for import of a new materialized view as part of offline instantiation.
END_LOAD Procedure	Completes offline instantiation of a materialized view.

BEGIN_LOAD Procedure

This procedure prepares a materialized view site for import of a new materialized view as part of offline instantiation. You must call this procedure from the materialized view site for the new materialized view.

Note: This procedure is used to perform an offline instantiation of a materialized view. These procedures should not be confused with the procedures in the DBMS_OFFLINE_OG package (used for performing an offline instantiation of a master table) or with the procedures in the DBMS_REPCAT_INSTANTIATE package (used for instantiating a deployment template). See these respective packages for more information on their usage.

Syntax

DBMS_OFFLINE_SNAPSHOT.BEGIN_LOAD (
   gname               IN   VARCHAR2,
   sname               IN   VARCHAR2,
   master_site         IN   VARCHAR2,
   snapshot_oname      IN   VARCHAR2,
   storage_c           IN   VARCHAR2 := '',
   comment             IN   VARCHAR2 := '',
   min_communication   IN   BOOLEAN  := true);

Parameters

Table 37-2 BEGIN_LOAD Procedure Parameters

Parameter	Description
gname	Name of the replication group for the materialized view that you are creating using offline instantiation.
sname	Name of the schema for the new materialized view.
master_site	Fully qualified database name of the materialized view's master site.
snapshot_oname	Name of the temporary materialized view created at the master site.
storage_c	Storage options to use when creating the new materialized view at the materialized view site.
comment	User comment.
min_communication	If true, then the update trigger sends the new value of a column only if the update statement modifies the column. Also, if true, the update trigger sends the old value of the column only if it is a key column or a column in a modified column group.

Exceptions

Table 37-3 BEGIN_LOAD Procedure Exceptions

Exception	Description
badargument	NULL or empty string for replication group, schema, master site, or materialized view name.
dbms_repcat.missingrepgroup	gname does not exist as a replication group.
missingremotemview	Could not locate specified materialized view at specified master site.
dbms_repcat.missingschema	Specified schema does not exist.
mviewtabmismatch	Base table name of the materialized view at the master and materialized view do not match.

END_LOAD Procedure

This procedure completes offline instantiation of a materialized view. You must call this procedure from the materialized view site for the new materialized view.

Note: This procedure is used to perform an offline instantiation of a materialized view. These procedures should not be confused with the procedures in the DBMS_OFFLINE_OG package (used for performing an offline instantiation of a master table) or with the procedures in the DBMS_REPCAT_INSTANTIATE package (used for instantiating a deployment template). See these respective packages for more information on their usage.

Syntax

DBMS_OFFLINE_SNAPSHOT.END_LOAD (
   gname           IN  VARCHAR2,
   sname           IN  VARCHAR2,
   snapshot_oname  IN  VARCHAR2);

Parameters

Table 37-4 END_LOAD Procedure Parameters

Parameter	Description
gname	Name of the replication group for the materialized view that you are creating using offline instantiation.
sname	Name of the schema for the new materialized view.
snapshot_oname	Name of the materialized view.

Exceptions

Table 37-5 END_LOAD Procedure Exceptions

Exception	Description
badargument	NULL or empty string for replication group, schema, or materialized view name.
dbms_repcat.missingrepgroup	gname does not exist as a replication group.
dbms_repcat.nonmview	This procedure must be called from the materialized view site.
