Best Practices for Handling queries for searching XML content

Experts: We have a requirement to get the count of 4 M rows from a specific XML tag with value begins with, I have a text index created but the query is extremely slow when I use the contains operator.
select count(1) from employee
where
contains ( doc, 'scott% INPATH ( /root/element1/element2/element3/element4/element5)') >0
what is oracle's best practices recommendation to query / index such searches?
Thanks

Can you provide a test case that shows the structure of the data and how you've generated the index? Otherwise, the generic advice is going to be "use prefix indexing".

Where to find best practices for tuning data warehouse ETL queries?

Hi Everybody,
Where can I find some good educational material on tuning ETL procedures for a data warehouse environment? Everything I've found on the web regarding query tuning seems to be geared only toward OLTP systems. (For example, most of our ETL
queries don't use a WHERE statement, so the vast majority of searches are table scans and index scans, whereas most index tuning sites are striving for index seeks.)
I have read Microsoft's "Best Practices for Data Warehousing with SQL Server 2008R2," but I was only able to glean a few helpful hints that don't also apply to OLTP systems:
often better to recompile stored procedure query plans in order to eliminate variances introduced by parameter sniffing (i.e., better to use the right plan than to save a few seconds and use a cached plan SOMETIMES);
partition tables that are larger than 50 GB;
use minimal logging to load data precisely where you want it as fast as possible;
often better to disable non-clustered indexes before inserting a large number of rows and then rebuild them immdiately afterward (sometimes even for clustered indexes, but test first);
rebuild statistics after every load of a table.
But I still feel like I'm missing some very crucial concepts for performant ETL development.
BTW, our office uses SSIS, but only as a glorified stored procedure execution manager, so I'm not looking for SSIS ETL best practices. Except for a few packages that pull from source systems, the majority of our SSIS packages consist of numerous "Execute
SQL" tasks.
Thanks, and any best practices you could include here would be greatly appreciated.

Online ETL Solutions are really one of the biggest challenging solutions and to do that efficiently , you can read my blogs for online DWH solutions to know at the end how you can configure online DWH Solution for ETL using Merge command of SQL Server
2008 and also to know some important concepts related to any DWH solutions such as indexing , de-normalization..etc

Best practice for opening/closing JDBC conection

I've written a program that accesses a database, and I'd like to know the best practice for opening and closing that connection. For example should I use a try{} finally {} block,
try
    //load driver
    //create conection
    //create statement object
    //sql statement to execute
    //execute statement
finally
    //close connection
}Or should I split the code into seperate methods, maybe an init() method that loads the driver and makes the connection and an execute() method that creates the statement and executes it and finally a cleanUp() method that closes the connection.
So, which would be the best way to do this?

Hallo,
your idea seems OK to me. However, there are a couple of points to consider:
1. Do you just want to execute one SQL query? Or will your program execute several? If the latter case is possible, then you do not want to close your connection between queries. Opening and closing a connection to a database takes 'a lot of time', relatively speaking. In this case, it is better to save the connection and reuse it every time that you need it.
2. Do not forget to close the statements and result sets that you create or get back from JDBC. Depending on the database (eg Oracle) that you are using, you can run out of cursors, and your application will stop.

Best practice for use of spatial operators

Hi All,
I'm trying to build a .NET toolkit to interact with Oracles spatial operators. The most common use of this toolkit will be to find results which are within a given geometry - for example select parish boundaries within a county.
Our boundary data is high detail, commonly containing upwards of 50'000 vertices for a county sized polygon.
I've currently been experimenting with queries such as:
select
from
uk_ward a,
uk_county b
where
UPPER(b.name) = 'DORSET COUNTY' and
sdo_relate(a.geoloc, b.geoloc, 'mask=coveredby+inside') = 'TRUE';
However the speed is unacceptable, especially as most of the implementations of the toolkit will be web based. The query above takes around a minute to return.
Any comments or thoughts on the best practice for use of Oracle spatial in this way will be warmly welcomed. I'm looking for a solution which is as quick and efficient as possible.

Thanks again for the reply... the query currently takes just under 90 seconds to return. Here are the results from the execution plan ran in sql*:
Elapsed: 00:01:24.81
Execution Plan
Plan hash value: 598052089
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 156 | 46956 | 76 (0)| 00:00:01 |
| 1 | NESTED LOOPS | | 156 | 46956 | 76 (0)| 00:00:01 |
|* 2 | TABLE ACCESS FULL | UK_COUNTY | 2 | 262 | 5 (0)| 00:00:01 |
| 3 | TABLE ACCESS BY INDEX ROWID| UK_WARD | 75 | 12750 | 76 (0)| 00:00:01 |
|* 4 | DOMAIN INDEX | UK_WARD_SX | | | | |
Predicate Information (identified by operation id):
2 - filter(UPPER("B"."NAME")='DORSET COUNTY')
4 - access("MDSYS"."SDO_INT2_RELATE"("A"."GEOLOC","B"."GEOLOC",'mask=coveredby+i
nside')='TRUE')
Statistics
20431 recursive calls
60 db block gets
22432 consistent gets
1156 physical reads
0 redo size
2998369 bytes sent via SQL*Net to client
1158 bytes received via SQL*Net from client
17 SQL*Net roundtrips to/from client
452 sorts (memory)
0 sorts (disk)
125 rows processed
The wards table has 7545 rows, the county table has 207.
We are currently on release 10.2.0.3.
All i want to do with this is generate results which fall in a particular geometry. Most of my testing has been successful i just seem to run into issues when querying against a county sized polygon - i guess due to the amount of vertices.
Also looking through the forums now for tuning topics...

Query Best Practice for Reports

I am new to Apex and I am wondering what is the best practice for store your sql quries for reports. I am a believer of storing all sql behind pacakge functions or procedures. And it looks like the only options for report pages are to use a direct SQL query, or a function that returns a query as a string. Yes the function method counts as putting the code in Oracle but not really. It is still getting compiled and parsed on the Apex side. It would be nice if Apex could handle a cursor but I have read that it doesn't directly. You have to have a function that returns a cursor and then create a pipelined function that calls the cursor function. That is kind of silly. Is there some other way to do this?
Apex 4.2
Oracle 11.2.0.2
Thanks for any input.
Jeff

Hi Jeff,
I'm not necessarily a believer in packaging queries. I'm a little more pragmatic in that I believe it may make sense in environments where you have a client environment that just expects a result set that is then manipulated by the client for the purposes of presentation, pagination etc. Apex has a different architecture in that the client is purely an HTML presentation layer (browser) and the presentation, pagination etc is formulated in the database along with the data using the Oracle web toolkit, which is a set of internal packages that produce HTML. Note that handling and manipulating ref cursors inside PL/SQL is not a joy, they were mainly designed to be passed out to external clients. (Often to shield programmers who don't or won't even try to understand relational concepts)
This means that when you create a report based on a query, the Apex engine will manipulate that base query, depending on the display requirements and pagination requirements of your report, before it submits that query to the database for execution. To get an idea of how this manipulation occurs, you can run your report in debug mode and check the actual query that is submitted to the database. If the query is presented as an already executed ref cursor, then the Apex engine can't execute in the way that it does. As you have already found out, the only way of using packaged queries returning ref cursors is by the use of a pipelined function, so that the Apex engine can treat the result as a normal query.
This is the architecture of Apex, and I suspect that re-engineering the Apex engine to handle ref cursors natively, as opposed to using a pipelining trick, would be a considerable change. I hope this at least helps to explain why ref cursors and Apex don't mix. I personally don't see the purpose of having an abstraction layer of packaged queries below an abstraction layer of an API such as Apex. SQL is a perfectly good API.

Best Practice for BEX Query "PUBLISH to ROLE"?

Hello.
We are trying to determine the best practice for publishing BEX queries/views/workbooks to ROLEs.
To be clear of the process I am referring: from the BEX Query Designer, there is an option QUERY>PUBLISH>TO ROLE. This function updates the user menu of the selected security role with essentially a shortcut to the BEX query. It is also possible to save VIEWS/WORKBOOKS to a role from the BEX Analyzer menu. We have found ROLE menus to be a good way to organize BEX queries/views/workbooks for our users.
Our dilemma is whether to publish to the role in our DEV system and transport to PROD,... or if it is ok to publish to the role directly in the PROD system.
Publishing in DEV is not always possible, as we have objects in PROD that do not exist in DEV. For example, we allow power users to create queries directly in PROD. We also allow VIEWS and WORKBOOKS to be created directly in PROD. It would not be possible to publish types of objects in DEV.
Publishing in PROD eliminates the issues above, but causes concerns for our SECURITY team. We would be able to maintain these special roles directly in PROD.
Would appreciate any ideas, suggestions, examples of how others are handling this BEX publish-to-role process.
Thank you.
-Joel

Hi Joel,
Again as per the Best Practices.Nothing to be created in PRD,even if we create them in PRD for Power users its assumed as temprory and can be deleted at any time.
So if there are already deviations then you can go for deviations in this case as well but it wont be the Best Practice.Also in few cases we have workbooks created in PRD as they cud nt be created in DEV due to various reasons...in such cases we did not think of Best Practice ,we had a raised an OSS on this aswell.
In our Project,we have done everything in DEV and transported to PRD,in case there were any very Minor changes at query level we have done in PRD and immedialtely replicated the same in DEV so that they are in SYNC.

Best practices for folder structure in SOA Project

Actually, In my project, I have more than 10 BPEL process and several DBAdapters and some HumanTasks. For each BPEL process, JDeveloper creates .bpel, .componentType, wsdl files. For DBAdapters JDeveloper creates lot of files, and same for HumanTasks as well.
By default Jdeveloper puts all these files in root directory of the Project. It looks messy having 100's of files in root directory.
How can I organize all these files?
What are the best practices for folder structure in SOA Project ?
Thanks

Yes Yatan. I did noticed that Polling service WSDL disabled in EM . But I want to try this approach beacause I want to move all database related stuff to one composite. I have another composite with 3 BPEL Processes. One BPEL queries external webservice and save the response in DB. One BPEL just fires the first Process(Query) and respond to caller with an unique id. I have Another BPEL which keeps polling on database for 5 sec(I'm using PICK Activity), if there is any new record in database it will retrun to caller. If no new records in database, returns empty to the caller after 5 sec.
If I put all these in one composite, having lot of files in root directory, the composite really looks very messy.
As you said, I want to have 2 composites. First Compoiste will have 3 BPEL processes, and 2nd Composite will have DB Polling and DB Save. I will have another project for MDS to store XSDs.
So because I can't have Polling service as exposed service, I have to keep Polling service in the same Composite where the BPEL is. Now again it goes back to Big and messy project.
Is there any way I can separate all DB related including polling in a separate Composite ?
Thanks

Universe Design Best Practices for Oracle

Hello All,
We recently moved from XIR2 on MS SQL 2005 to XI 3.1 on Oracle. This has been a difficult move for us as my team is new to oracle. I'm currently working on several performance issues between BOBJ and Oracle and am looking for documentation on best practices for universe design with oracle. I've foudn tidbits here and there regrading using parameters joing_by_sql and boundary_weight_table, wondering if there are other options out there that might help. We have queries taking 45+ minutes to run and that is totally unacceptable.
thanks

Best practices for setting up users on a small office network?

Hello,
I am setting up a small office and am wondering what the best practices/steps are to setup/manage the admin, user logins and sharing privileges for the below setup:
Users: 5 users on new iMacs (x3) and upgraded G4s (x2)
Video Editing Suite: Want to connect a new iMac and a Mac Pro, on an open login (multiple users)
All machines are to be able to connect to the network, peripherals and external hard drive. Also, I would like to setup drop boxes as well to easily share files between the computers (I was thinking of using the external harddrive for this).
Thank you,

Hi,
Thanks for your posting.
When you install AD DS in the hub or staging site, disconnect the installed domain controller, and then ship the computer to the remote site, you are disconnecting a viable domain controller from the replication topology.

Best-practice for Catalog Views ? :|

Hello community,
A best practice question:
The situtation: I have several product categories (110), several items in those categories (4000) and 300 end-users. I would like to know which is the best practice for segment the catalog. I mean, some users should only see categories 10,20 & 30. Other users only category 80, etc. The problem is how can I implement this ?
My first idea is:
1. Create 110 Procurement Catalogs (1 for every prod.category). Each catalog should contain only its product category.
2. Assign in my Org Model, in a user-level all the "catalogs" that the user should access.
Do you have any idea in order to improve this ?
Saludos desde Mexico,
Diego

Hi,
Your way of doing will work, but you'll get maintenance issues (to many catalogs, and catalog link to maintain for each user).
The other way is to built your views in CCM, and assign these views to the users, either on the roles (PFCG) or on the user (SU01). The problem is that with CCM 1.0 this is limitated, cause you'll have to assign one by one the items to each view (no dynamic or mass processes), it has been enhanced in CCM 2.0.
My advice:
-Challenge your customer about views, and try to limit the number of views, with for example strategic and non strategic
-With CCM 1.0 stick to the procurement catalogs, or implement BADIs to assign items to the views (I experienced it, it works, but is quite difficult), but with a limitated number of views
Good luck.

Best Practice for Securing Web Services in the BPEL Workflow

What is the best practice for securing web services which are part of a larger service (a business process) and are defined through BPEL?
They are all deployed on the same oracle application server.
Defining agent for each?
Gateway for all?
BPEL security extension?
The top level service that is defined as business process is secure itself through OWSM and username and passwords, but what is the best practice for security establishment for each low level services?
Regards
Farbod

It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
You can enforce rules at your network layer to allow access to the App server only from Gateway.
When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
The next BPEL developer in your project may not be aware of Security extensions
Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.
Thanks

Best practice for multi-language content in common areas

I've got a site with some text in header/footer/nav that needs to be translated between an English and Spanish site, which use the same design. My intention was to set up all the text as content to facilitate. However, if I use a standard dialog with the component's path set to a child of the current page node, I would need to re-enter the text on every page. If I use a design dialog, or a standard dialog with the component's path set absolutely, the Engilsh and Spanish sites will share the same text. If I use a standard dialog with the component's path set relatively (eg path="../../jcr:content/myPath"), the pages using the component would all need to be at the same level of the hierarchy.
It appears that the Geometrixx demo doesn't address this situation, and leaves copy in English. Is there a best practice for this scenario?

I'm finding that something to the effect of <cq:include path="<%= strCommonContentPath + "codeEntry" %>" resourceType ...
works fine for most components, but not for parsys, or a component containing a parsys. When I attempt that, I get a JS error that says "design.path is null or not an object". Is there a way around this?
