3 -- PACKAGE NAME
4 -- dbms_logmnr_d
5 --
6 -- DESCRIPTION
7 -- This package contains Logminer Dictionary related procedures.
8 -- "build" is used to gather the logminer dictionary.
9 --
10 -- "set_tablespace" is used to alter the default tablespace of
11 -- Logminer tables.
12 --
13 -- BUILD
14 -- The logminer dictionary can be gathered
15 -- into a flat file (Logminer V1 behavior) or it can be gathered
16 -- into the redo log stream.
17 --
18 -- When creating a Flat File dictionary the procedure queries the
19 -- dictionary tables of the current database and creates a text based
20 -- file containing their contents. Each table is represented by
21 -- "pseudo" SQL statements. A description of the columns in a
22 -- table is created by a "CREATE_TABLE" line (one statement for
23 -- table). It contains the name, datatype and length for each
24 -- column. A "INSERT_INTO" statement is created for each row in a
25 -- selected table. It contains the values for each row. The file
26 -- is created in preparation of future analysis of databases
27 -- log files using the logminer tool.
28 --
29 -- When gathering the system dictionary into the logstream the procedure
30 -- queries the dictionary tables inserting the results into a special
31 -- set of Logminer Gather tables (SYS.LOGMNRG_*). A side effect of
32 -- each query is that the resultant inserts cause redo to be generated.
33 -- Down stream processing can mine this redo to determine the contents
34 -- of this system's system dictionary at the time this procedure was
35 -- executed.
36 --
37 -- NOTE: Database must be in "Archivelog Mode" and supplemental logging
38 -- must be enabled for this procedure to run
39 --
40 -- BUILD INPUTS
41 -- dictionary_filename - name of the dictionary file
42 -- dictionary_location - path to file directory
43 -- options - To explicitly indicate flat file or log stream destination.
44 --
45 -- BUILD EXAMPLE1
46 -- Creating a dictionary file as:
47 -- /usr/ora/dict.ora
48 -- Complete syntax, typed all on one line:
49 --
50 -- SQL> execute dbms_logmnr_d.build('dict.ora',
51 -- '/usr/ora',
52 -- DBMS_LOGMNR_D.STORE_IN_FLAT_FILE);
53 --
54 -- BUILD EXAMPLE2
55 -- Creating a dictionary file as:
56 -- /usr/ora/dict.ora
57 -- Logminer V1 syntax.
58 --
59 -- SQL> execute dbms_logmnr_d.build('dict.ora', '/usr/ora');
60 --
61 -- BUILD EXAMPLE3
62 -- Gathering a dictionary into the log stream
63 -- Complete syntax, typed all on one line:
64 --
65 -- SQL> execute dbms_logmnr_d.build('', '',
66 -- DBMS_LOGMNR_D.STORE_IN_REDO_LOGS);
67 --
68 -- BUILD NOTES
69 -- The dictionary gather should be done after all dictionary
70 -- changes to a database and prior to the creation of any log
71 -- files that are to be analyzed.
72 --
73 --
74 -- SET_TABLESPACE
75 -- By default all Logminer tables are created to use the SYSAUX
76 -- tablespace. All users will find it desirable to alter Logminer
77 -- tables to employ an alternate tablespace. Use this routine to
78 -- recreate all Logminer tables in an alternate tablespace.
79 --
80 -- SET_TABLESPACE INPUTS
81 -- new_tablespace - a string naming a preexistant tablespace.
