Impact when increase the wildcard_maxterms attribute value

In some queries the output was
ORA-29902: error in executing ODCIIndexStart() routine
ORA-20000: interMedia Text error:
DRG-51030: wildcard query expansion resulted in too many terms.
I found that to solve this problem must create a wordlist as follows
exec ctx_ddl.create_preference('MYWORLD_LIST','BASIC_WORDLIST');
exec ctx_ddl.set_attribute('MYWORLD_LIST', 'WILDCARD_MAXTERMS', 15000);
This because the default value of 'WILDCARD_MAXTERMS' is 5000.
and then alter the index as follows
ALTER INDEX my_index rebuild parameters('replace wordlist MYWORLD_LIST');
My question is If I do this thing which is the impact If there is, in
index maintenance,DML processing, disk resourses,index memory,and finally impact on rollback segment.

This number only effect the search criteria... a count.
I don't think that this will cause any performace issues with the ROLLBACK Segment.
This number only tell the database that now it can do a wilcard search upto 15000.
So if you query were resulting into more then 5000 this change will allow you to query upto 15000. However if your search still result more then 15000 it will error out.
Bottom line.. There is no performace hit on RBS& INDEX MANINTENACE..
However you search will get slower.
Shah Nawaz Thanks for the tip.

Hi,
The issue here is the mapping of the interface to the service in question, and usually points to a possible mistype or rename of something within your service architecture.
You need to make sure your namespace and service name here match your service name itself.
For detailed information, you could refer to:

Can we update the Category attribute values of a file

Can we update the Category attibute values of a file with out checkout the file?
I have set the version configuration to folder and try to update the category attribute values of a file under that folder,
It is asking to checkout the file before modifying the category attibute values.
Is it required to checkout the file before modifying the category attribute values of that file?
Is there any way to update the category attribute values without checkout the file?
Please help on this

One of the ways i can think of is using Batch Loader script for large number of files. Mention such files in Batch Loader script, and it will update category and all meta-data required in terms of next revision.
In case number of files are less manual checkout and check-in will help.

Is it possible to increase the substitution variable value length?

Hi,
Is it possible to increase the substitution variable value length to higher value? I checked the SQL User Guide (http://download.oracle.com/docs/cd/B19306_01/server.102/b14357/apa.htm) and it says that the limit is 240 characters.
i just want to know any workaround for this issue?
Thanks.

How to increase the request timeout value in Oracle 10g web container

Hi,
Iam using Oracle10g Application server .
For long running backend process my JSP page is getting re-submitted after 3 mins.
How do i avoid this ?
Is there a way to increase the http request timeout interval.
If so where do i change the timeout interval.
In IIS web server I can change the timeout interval.
Thanks
Sridhar.

Hi,
If you mean to increase the request timeout i.e the time when a request is submitted to the server and the response is sent by the server it can be done in httpd.conf file located in $OracleHome/Apache/Apache/conf directory.
The attribute to be used for setting timeout is "Timeout". By default teh value is 600 seconds i.e 5 minutes.
After making these changes , run command dcmctl updateConfig -ct OHS and restart the HTTP Server. Please note these commands need to be run only if the httpd.conf changes are done through text editor.
Hope this helps.

How to get the VO attribute value by groovy?

Hi everyone,
I have a ItemsVO (with an entity behind it), a CompaniesVO and BusinessVO. CompaniesVO is filtered by a ExecuteWithParams, and has a type attribute, with this attribute I can filter BusinessVO used as LOV in ItemsVO. How can I pass the value using a groovy expression in the view accesor? Can I do this?
Thanks in advance.

Hi
If there is a master child relation between CompaniesVO and BusinessVo, then define a viewLink and create view accessors and you can access the another view object attributes from groovy like 'view accessor name.attribute name'.
Make sure you set the bind var value type as expression. And for example please refer to the below link by andrejus b.

When using the placholder attribute in an input field with a dark background, why can't the blinking caret be white on focus?

Chrome and Safari both do this, making it clear to the user that they're in the field and ready to type. Currently the caret will take the color property but only once the user has started typing. This seems like it would be a worthwhile feature to bake into the next build of FF.

I have a separate java class that gets my data and returns a Result object. Do you mean java.sql.ResultSet?
In my main servlet I do the following:
request.setAttribute("supporttracker",
supporttracker.findsupporttracker(monthYear));
and then in my JSP I can iterate through the Result
like the following with no problems:
<c:forEach var="supporttracker" begin="0"
items="${supporttracker.rows}" varStatus="counter">
My problem is that I can only iterate through this
once in the page whereas I have no problem doing
multiple forEach loops through other types of
lists/collections such as an ArrayList. Right, because a ResultSet is a database cursor and doesn't act the same way that an ArrayList does. It's more like an InputStream - once you read it, you close it. If you want to re-read it, you have to re-initialize it again.
Iterators behave that way, too. Once you walk through them, you have to re-initialize them.
I've looked
on the web and in a couple of books, I first thought
it may be scope or some attribute in forEach that I
was missing but I'm stumped. It seems like it's
because the pointer to the result set is at the end
of the result set when trying the second iteration,
but I thought by using the begin="0" would put the
pointer at the first row again, on my second
iteration I'm getting no rows/data outputed.
Please help and thanks in advance!The better thing to do is for your method to return a List of objects, one per row, that represent what the ResultSet returns. Have that method iterate through the ResultSet, loading the rows into the List, and close it before you leave in a finally block. A database cursor is a scarce resource, so it's a good idea to close it as soon as you can.

How to get the one attribute value in another attribute getter method

Hi,
I have a requirement to get one attribute's value in the another attribute getter or setter method.
Help needed ASAP.
Thanks,
sreenivas.

Check if both the attributes are under the same context node.
If so directly call the getter method of the other attribute here like this:
lv_customer_type = me->get_customer_type( attribute_path = 'STRUCT.CUSTOMER_TYPE' ).
If it is under a different context node,check if it is available from some relation, if so
    lr_agr_rel = current->get_related_entity( iv_relation_name = 'TpmAgrre'l ).
     CALL METHOD lr_agr_rel->if_bol_bo_property_access~get_property_as_value
        EXPORTING
          iv_attr_name = 'EXTERNAL_ID'
        IMPORTING
          ev_result    = lv_cust_plan_id.

CS4 + CS5 Brush CURSOR outline disappear when increase the brush size

Hi
In Photoshop CS4 and CS5, the outline of the brush cursor starts to disappear when you increase the brush size.

Change the Summary Attribute Value through Java code

Hi ,
I am working on a requirement where I need to set the Attribute value on the final Summary Screen through Java Code.
Code :
        InterviewUserData data = new InterviewUserData();
        InterviewEntityInstance globalInstance = data.getGlobalInstance();
        globalInstance.setValue("Name", value_to_set);
On completion of the interview session Name is displaying as NULL.
I need to set NAME = value_to_set and display it on the final summary screen.
Any help on this will be appreciated.
Regards

The InterviewUserData object is effectively a change set, to apply this to a session you use the InterviewSession.submit(InterviewUserData) method. You don't say how you are invoking this code but if it's inside an event Interview Engine handler the InterviewSession object should be accessible.

How to handle & or when part of an attribute value

In my xml file, i have &(ampersand) or > as part of the attribute value.As a result i get SAXParserExeption. Is there a way to handle this error other than writing & as & in the xml file.
<p>
Thanks.

Dear DrClap,
Thanks for the solution, but i have been using it already. I would like some other alternative. Is there some kind of Handler to deal with such issues or do we write some code to handle it..If so, could someone please help me out with this..
Thanks.

Get the message attribute values in Orchestration without using property promotion

I have the following schema :
Now I want to get the values of FName,LName in orchestration without using any property promotion ?
Prakash

There are also multiple ways of creating the Xpath:
- Full path with namespaces - Rahul Madaan showed this one
- Full path without namespaces:
FName = xpath(InputMessage, "string(/*[local-name()='Root']/*[local-name()='IntField'])");
I think this method is handy if you have multiple schemas with similar structure but the namespace
changes. This is also easier to read and less prone to errors if there are any changes.
If you for example wanted the node #3, then it would be
FName = xpath(InputMessage, "string(/*[local-name()='Root']/*[local-name()='IntField'][3]/*[local-name()='IntSubField'])");
- Jump directly to the field/node you need (this one works for at least xml elements):
xpath(InputMessage, "string(//*[local-name()='IntField'])");
I find this useful when picking up key-values from the message, that can be available only once.
All the examples above are for elements. Since you are picking up value from an attribute, the actual structure
is
varFName = xpath(InputMessage,"string(/*[local-name()='StudentDetails']/*[local-name()='Student']/@*[local-name()='FName'])");
And to learn the rest of the possibilities of Xpath, like count, different types, more detailed selections
of the correct Node (Like example, I want only the one where FNAME = 'MyFName') You can try something like: http://social.technet.microsoft.com/wiki/contents/articles/6944.biztalk-orchestrations-xpath-survival-guide.aspx
Also get DanSharp XmlViewer. It will help you quite a bit when fine tuning the xpaths.
