Effective Implementation

Hi,
I am in the process of evaluating the existing Implementation of Fulltext
Index in our product(sql server 2000).We have full text index (text type) in
a table with out timestamp column.The existing settings for creation and
maintenance are ,
sp_fulltext_catalog 'test_catalog', 'create'
sp_fulltext_table 'test', 'create', 'test_catalog', 'test_pk'
sp_fulltext_column 'test', 'value', 'add'
sp_fulltext_table 'test', 'activate'
sp_fulltext_catalog 'test_catalog', 'start_incremental'
I think the above setting should populate the Index.
And then they have a process which is invoked every 2 minutes and does the
following.My contention is this will ne never invoked ..If yes , then how do
i implement incremental indexing ...If no , pls tell me the scenarions under
which this will get invoked...(assume usingChangeTracking=true)
boolean usingChangeTracking = KanaServer.getDBLink().isSqlServer() &&
ParameterHelper.getParameterValueBoolean(liveNode. getParameter("UseFullTextChangeTracking"));
if (usingChangeTracking) {
//check if ChangeTracking and BackgroundUpdatingIndex are on, if not,
turn it on
if (DBAccess.readInteger ("SELECT ObjectProperty (Object_ID('test'),
'TableFullTextChangeTrackingOn')") == 0) {
KanaPrint.println("Start change tracking for Microsoft FullText
Index");
DBAccess.executeNoTransactions(new String[] {"sp_fulltext_table 'test',
'Start_change_tracking'"});
}
if (DBAccess.readInteger ("SELECT ObjectProperty (Object_ID('test'),
'TableFullTextBackgroundUpdateIndexOn')") == 0) {
KanaPrint.println("Start background updating for Microsoft
FullText Index");
DBAccess.executeNoTransactions(new String[] {"sp_fulltext_table 'test',
'Start_background_updateindex'"});
}
return;
}

Rect,
If I correctly understand that "test_catalog" is the true name of your FT
Catalog for your FT-enabled table "test", then there is a difference between
the code examples you provided. Specifically, your code runs an Incremental
Population against the FT Catalog "Test", while the Change Tracking with
Update Index in Background is operating on the FT-enabled table "Test"
within the FT Catalog "test_catalog":
sp_fulltext_catalog 'test_catalog', 'start_incremental'
-- vs.
sp_fulltext_table 'test', 'Start_change_tracking'
sp_fulltext_table 'test', 'Start_background_updateindex'
Additionally, as your table does not have a timestamp column, when you start
an Incremental Population or enable Change Tracking, what is executed is a
Full Population (see BOL title "sp_fulltext_table" and under
start_change_tracking - "If the table does not have a timestamp, start a
full population of the full-text index". Furthermore, it is not necessary to
invoked every 2 minutes, as once CT with UIiB is enabled it is set until it
is changed.

|||Thanks John for your reply.
Does that mean the followig scripts run once , would do the job.Pls
confirm... I did some cut & paste job to hide my original table name..I am
attaching here the original scripts..
sp_fulltext_database 'enable'
sp_fulltext_catalog 'kc_rawtext_catalog', 'create'
sp_fulltext_table 'kc_rawtext', 'create', 'kc_rawtext_catalog',
'kc_rawtext_pk'
sp_fulltext_column 'kc_rawtext', 'value', 'add'
sp_fulltext_catalog 'kc_rawtext_catalog', 'start_incremental'
--Not required right ?..
And then one time invokation of the following..
sp_fulltext_table 'kc_rawtext', 'Start_change_tracking'
sp_fulltext_table 'kc_rawtext', 'Start_background_updateindex'
Also tell me if i am wrong , restart of mssearch will cause full population
of the catalogs...?
Rect
sp_fulltext_table 'kc_rawtext', 'activate'
Pls review the same and give your feedback..

Yes, that is what I mean. Specifically that running the "Change Tracking"
and "Update Index in Background" should be only run once. However, I'd also
recommend that you alter the table and add a timestamp column and then set
the CT with UIiB first without running a Full Population as setting the CT
with UIiB will run automatically run a Full Population on an un-populated FT
Catalog or if it is populated, it will run an Incremental Population, but in
your case without a timestamp column it will run a Full Population.
There is no need to run both an Incremental Population when you have CT with
UIiB set, unless you have massive (>50%) updates to the table. See BOL title
"Maintaining Full-Text Indexes" for more details on when to use turn off
UIiB and use an Incremental or Full Population with Change Tracking.

John

|||Thanks John.I shall remove the code for start_incermental portion and rest
will be run as one time activity for the fresh set-ups.Altering the table to
have timestamp column will be big exercise as many of the customers are using
this option already , as it will involve code changes also on the application
front.
