Performance of workspace manager

I have created versioned tables in Oracle 9.2. It sits in DEC Unix OS. I have experienced performance degredation after versioning the tables. The largest table has about 20 million rows. Do I need to analyze the base table generated by versioning the tables?
Help!

Analyzing the base table should definitely help performance. Also, if you think it will help, feel free to send me mail with your phone and we can have a conference call to help you with the performance issues.

Workspace manager performance

Hi
I'm a Java developper trying to act as a DBA so don't fire !
I'm trying to use the workspace manager on a 21M record DB
on Oracle 10g/Windows.
I'm bulkloading using sqlloader into it. The load phase is done
with good performance (or at least it seems to me), in
about 30 minutes, which is consistent to numbers I get when
I load in a non-version enabled table.
When I do the commitbulkloading though, it takes about 55 minutes
to complete. I realized 2 things:
1- it takes quite a lot of time creating and populating the discards table
with the entire content of the original table (!) - which looks like a bug
to me
2- it spends tremendous amount of time doing:
SELECT count(*)
FROM listings_lt t1, listings_lt t2
WHERE t1.listing_id = t2.listing_id
AND t1.delstatus IS NULL
AND t1.version = 0
AND t2.delstatus IS NOT NULL
where listings_id is my PK on the listings_lt table.
I solved 1 by simply creating the discards table before calling commit -
then it does not create or populate it. But 2 puzzles me. I
specified check_for_duplicates=FALSE in the CommitBulkLoading
API but it did not change anything.
Any ideas to speed things up ?

Hi,
Yes, #1 does indeed look like a bug. The current workaround to this is to create the discards table before calling commitBulkLoading as you indicated. This will be fixed.
The query in #2 is not used to check for duplicates. It is used to determine if all the keys that are being inserted are unique. There is currently no way to avoid this select, as it is needed internally by the commitbulkloading procedure. To increase its performance, I would recommend to analyze the table using dbms_stats before calling commitbulkloading. However, please note that when bulk loading 21M records into an empty table, this query will require a full table scan.
If that does not help, then post the execution plan for the statement. From that I may be able to determine if something else needs to be done.

Ben

Analytic Workspace Manager 9.2.0.4

Hi
When I attempt to create a workspace in Analytic Workspace Manager an error message is displayed saying that the database I am using is not a 9.2.0.2 compatible database and the DBMS_AWM package cannot be found.
I have, however, patched my database to 9.2.0.5. Is Analytic Workspace Manager version 9.0.4 incompatible with Oracle DB version 9.2.0.5?
My environment setup is as follows:
Analytic Workspace Manager (9.2.0.4)
Oracle DB 9i Rel 2 (9.2.0.5)
Windows XP Professional SP 2.
Thanks
Ryan

AWM 9.2.0.4.1 is forward compatible on the 9.2 code stream. It works with the current 9.2.0.5.0 and 9.2.0.6 patch sets. My guess is that the Post Installation steps for the 9.2.0.5.0 patch set were not performed. For example, did the catpatch.sql script run? A lot of people overlook this required step in the readme.
In order to check to see if your patch set was installed correctly, perform the following query:
SQL> select comp_name, version, status from dba_registry;
You should see 9.2.0.5 and VALID for the OLAP components.

Workspace manager to journal application tables?

Hi,
I know nothing about WSM. We need to provide a full audit
trail (journalling) for certain tables in a new application (Oracle 9i, Appl server 10g).
We were planning to generate this using API generator in Designer.
Question is - could WSM do this less painfully?.
If historical data is stored, can user reports be defined against it (Users may need to run queries against changes made to application data).
We would be grateful for any info.

Hi Steve,
I'm the Product Manager. Feel free to contact me directly at [email protected] to discuss your auditing requirements.
In general, yes, Workspace Manager can maintain a history of changes to a table.
It can make a timestamped copy of a row every time a change to it is committed. The GotoDate command allows the user to set session context to a particular point in time to see the database (including the changed rows) as it was at that time.
DML doesn't need to change (unless hints are needed to optimize performance). All historical copies of the rows are kept in the same table as the original row.

Workspace Manager & Slowly Changin Dimension in Data Warehouse

Has anyone used Workspace Manager in a Slowly Changing Dimension to keep history in a Data Warehouse.
What issues have you come across?
What are advantages?
What are disadvantages?
Thanks
Uli

Hi Ben,
thanks for getting back on this and sorry for not updating earlier.
I had a brief scan through the documentation and Workspace Manager seems to be quite powerful. When I was reading through the docs originally I had the idea that this might be useful to reduce coding and improve performance in a Slowly Changing Dimension (type 2) DW scenario. I would hope for a performance improvement in both loading and querying data. So I thought before I get my hands dirty and do some tests I would check with the community to see if this is something that has been done before.
To answer your specific questions: I would like to keep every change. I would not need the primary workspace functionality for merging and version control etc. It would just be to keep history.
Again thanks for your efforts.
Uli

Can Designer 9i generate Workspace Manager versioned tables?

All,
I am exploring the use of the Oracle 9i feature Workspace Manager.
Can Designer 9i generate versioned tables for a Workspace Manager enabled instance. I know that the tables could be generated to scripts and then edited to properly alter versioned tables. However manually editing each script is not a long term solution. I have read through the application help, newsgroups, and this discussion group and did not find any information.
I welcome any input you have to offer,
Doug

Workspace Manager Speed

Hi all,
I have just tested the workspace manager performances and compared them to non version enabled tables. It seems the workspace manager is pretty slow compared to not using it.
Is this normal ? Is there any type of information or survey about the speed ratio between with and without worspace manager in place ?
Thanks a lot
Hugues

Hi,
I do not have much experience with Oracle text, and am unsure exactly how it works. As such, I would suggest to file a TAR requesting this information.

Workspace manager and Streams

I wanted to know if workspace manager support streams.
If it supports, can Advanced replication and workspace manager co-exist in a database?
We currently have advanced replication between 2 database with workspace manager installed. The tables are version enabled and replicated. We are adding a new database that is going to use Streams for data movement instead of advanced replication. I would like to know if they can co-exist?
Thanks.

Hi,
There are a number of different modes in collecting data when using Streams. If the LCR records are being created using the redo log, then you would need to specify the LT table when adding support. Otherwise, if a custom application was creating its own LCRs (for example, via triggers) it would not have to use the LT table, but could create the records based on the column values in the trigger.
Also, I should note that it would not really be feasible to replicate the versioned tables completely using streams on top of Workspace Manager. The types of operations that I was referring to that could be performed would be moving data into a non-versioned table. For example, creating a rule so that only specified rows or a particular workspace are streamed into a table at a different database. The metadata would also need to be removed from the record, which would only be useful in a versioned environment. Aside, from these types of activities, advanced replication would need to be used.

Ben

Upgrading from 9.0.1.3 to 11.2.0.4 with Oracle Workspace Manager

Our client has a (very old) 9.0.1.3 database on Windows 2000
This database (and other products – but that’s not the main concern right now) needs to be upgraded to 11.2.0.4 in Windows2008R2 (64 bit).
A complicating factor might be the use of Oracle Workspace Manager – a lot of tables are Workspace Managed.
We can do it the long way, by upgrading it via 9.1.0.4, 10.2.0.1, 10.2.0.4 -> Export and then, on the new environment, import on 10.2.0.4 en subsequently upgrade it to 10.2.0.5 and then 11.2 (and maybe some more patching afterwards).
But that takes way too long (downtime).
So would it be possible to do it the “easy way”:
Full Database Export of 9.0.1.3, import it into a brand new empty 11.2.0.4 and then upgrade Workspace Manager to 11.2 as well?
Or should we upgrade OWM to 11.2 in the old environment - and is that possible at all?
(FYI: Snippet from the OWM manuals : Workspace Manager supports the import and export of version-enabled tables in one of the following two ways: a full database import and export, and a workspace-level import and export through Workspace Manager procedures. No other export modes, such as schema, table, or partition level, are currently supported).
(On purpose cross-posted in the "Workspace Manager" Forum : Upgrading from 9.0.1.3 to 11.2.0.4 with Oracle Workspace Manager

The database is not that big (in fact there are two, both around 130Gb).
Affordable downtime is one weekend. The long way (with all patching and upgrading) takes around 100 hours...
We did raise an SR, but the answer was ... take the long way home ;-)
(But, FYI, I didn't raise the SR, so I don't know what question has been asked... If the original question was "how to upgrade", you get the official statement. If you don't ask for other options, you don't get them - so I ask it here...)
And I've seen that presentation... Thanks anyway.

How to install analytic workspace manager?

I have Oracle 9.2.0.1 running on Windows. I have installed 9.2.0.3 database patch. I couldn’t see analytic workspace manager tool? How to get the tool?
I will greatly appreciate if you can guide me with some links or steps.

Few days back I went to a Oracle Demo and there I used Analytic Workspace Manager, which is running on Windows 2000 (both database and the tool on same machine).
It was located in
Start menu --> Oracle home --> Integrated Management Tolls Folder.
I couldn't see that on my 9.2.0.1 installation. So I installed the new patch 9.2.0.3, still I am not able to see that tool.
Am I missing anything? Any other patch?
