39 -- Effects: This routine adds a new site "new_site" to the object group
40 -- "gname." It readies the new site for offline importation of the
41 -- group's objects. The fname parameter is reserved for internal use.
42 -- Do not specify this parameter unless directed
43 -- by Oracle Worldwide Customer Support.
44 -- The state of the replicated object group must be
45 -- QUIESCED before this routine is run; otherwise, an exception
46 -- is raised. This routine must be run at the master definition site.
47 -- Raises the following exceptions:
48 -- badargument:
49 -- if "gname" or "new_site" is NULL or ''
50 -- dbms_repcat.nonmasterdef:
51 -- if the site this routine is executing at is not the
52 -- master def. site.
53 -- sitealreadyexists:
54 -- if "new_site" is already a new master site
55 -- wrongstate:
56 -- if master def site is not in QUIESCED state
57 -- dbms_repcat.missingrepgroup:
58 -- if "gname" does not name an object group
59 -- dbms_repcat.missingflavor:
60 -- if "fname" does not name a published flavor
61 -- for the object group

63 PROCEDURE begin_instantiation (gname IN VARCHAR2,
64 new_site IN VARCHAR2,
65 fname IN VARCHAR2 := NULL);
66
67 -------------------------------------------------------------------------
68 -- Effects: For the object group "gname" this routine resumes
69 -- normal activity for all master sites except for the new site
70 -- "new_site." The state of the replicated object group at each site
71 -- must be QUIESCED; otherwise, an exception is raised. When this
72 -- routine returns normally, all sites are in the NORMAL state except
73 -- for the new site, which is still in the QUIESCED state. This
74 -- routine disables propagation of the queues from all sites
75 -- originally in the object group to the new site "new_site." It
76 -- is meant to prevent the pushing of the queues to the new site
77 -- until the new site is instantiated.
78 -- This routine must be executed at the master definition site.
79 -- Raises the following exceptions:
80 -- badargument:
81 -- if "gname" or "new_site" is NULL or ''
82 -- dbms_repcat.nonmasterdef:
83 -- if the site this routine is executing at is not the
84 -- master def. site.
85 -- unknownsite:
86 -- "new_site" not known to object group
87 -- wrongstate:
88 -- if master def site is not in QUIESCED state

95
96
97 -------------------------------------------------------------------------
98 -- Effects: For object group "gname" this routine integrates the site
99 -- "new_site" into the set of existing sites. When the routine returns
100 -- normally, all sites can communicate with each other.
101 -- This routine re-enables propagation of the queues from all sites
102 -- originally in the object group to the new site "new_site."
103 -- Applications may now push the queues to the new site, now that it is
104 -- instantiated. All sites in the object group are in the NORMAL state.
105 -- This routine must be executed at the master definition site.
106 -- Raises the following exceptions:
107 -- badargument:
108 -- if "gname" or "new_site" is NULL or ''
109 -- dbms_repcat.nonmasterdef:
110 -- if the site this routine is executing at is not the
111 -- master def. site.
112 -- unknownsite:
113 -- site "new_site" is not known to schema "sname".
114 -- wrongstate:

122 -------------------------------------------------------------------------
123 -- Effects: Starts the instantiation or migration of the object group
124 -- "gname" at site "new_site." When this routine returns normally, this
125 -- site is readied for loading or migrating user-defined tables.
126 -- The site must be in the QUIESCED state when this routine is
127 -- invoked; otherwise an exception is raised. It disables
128 -- propagation of the queues from the site "new_site" to
129 -- all sites originally in the object group. This routine must
130 -- be invoked at the site.
131 -- Raises the following exceptions:

133 -- if "gname" or "site" is null or ''
134 -- wrongsite:
135 -- routine is not executing against site "site"
136 -- unknownsite:
137 -- "site" is an unknown master site

146 -------------------------------------------------------------------------
147 -- Effects: This routine ends the instantiation of object group
148 -- "gname" at site "new_site" and resumes normal activity. It verifies
149 -- the local object group is at the given flavor. The site
150 -- must be in the NORMAL state; otherwise, an exception is raised.
151 -- It re-enables propagation of the queues from the new site
152 -- "new_site" to all the sites originally in the object group
153 -- before the new site was added. The object group is now ready
154 -- for normal activity that, from now on, will involve the new
155 -- site. The fname parameter is reserved for internal use.
156 -- Do not specify this parameter unless directed
157 -- by Oracle Worldwide Customer Support.
158 -- Raises the following exceptions:
