Activating Permanent Journaling - Analytics Database - Teradata Vantage

If you specify only DEFAULT JOURNAL TABLE = table_name, then the system creates a journal table, but does not activate it.

To activate the permanent journal, you must also specify either the AFTER JOURNAL journaling option or the BEFORE JOURNAL option or both.

This action causes permanent journaling to be activated for all tables created in this database afterward.

To determine which tables in your system are journal tables, use the following query:

SELECT DBC.dbase.databasename (FORMAT 'X(15)'),
DBC.tvm.tvmname (FORMAT 'X(25)')
FROM DBC.tvm,DBC.dbase
WHERE DBC.dbase.databaseid=DBC.tvm.databaseid 
AND   DBC.tvm.tablekind='j'
ORDER BY 1,2;

To determine which databases and users in your system currently have a default journal table defined for them, use the following query:

SELECT d.databasename (TITLE'Database'),TRIM(dx.databasename)
||'.'||TRIM(t.tvmname)(TITLE 'Journal')
FROM DBC.dbase AS d,DBC.TVM AS t, DBC.dbase AS dx
WHERE d.journalid IS NOT NULL
AND   d.journalid <> '00'xb
AND   d.journalid = t.tvmid
AND   t.databaseid = dx.databaseid
ORDER BY 1;

To determine which tables in your system are currently being journaled, use the following query:

SELECT TRIM(Tables_DB)||'.'||TableName (TITLE 'Table',
CHARACTER(26)),'Assigned To' (TITLE ' '),TRIM(journals_db)
||'.'||JournalName (TITLE 'Journals', CHARACTER(26))
FROM DBC.journals
ORDER BY 1,2;

You can also determine which tables in your system are currently being journaled using the following query that has a somewhat different syntax:

SELECT TRIM(d.databasename)||'.'||TRIM(t.tvmname) (FORMAT
'x(45)',TITLE 'Table'),TRIM(dj.databasename)
||'.'||TRIM(tj.tvmname) (TITLE 'Journal')
FROM DBC.TVM  AS t, DBC.TVM  AS tj, DBC.dbase AS d, DBC.dbase AS dj
WHERE t.journalid IS NOT NULL
AND   t.journalid <> '00'xb
AND   t.journalid = tj.tvmid
AND   d.databaseid = t.databaseid
AND   dj.databaseid = tj.databaseid
ORDER BY 1;
