Querying a collection object

I have an objects as follows
Entity {
key k;
Collection<Person> personList;
Person{
Address address;
Address{
String zipcode;
I want to get all the Entities coming under "zipcode=123456".
Please help me how to get it using the query.
TIA.

Hi,
One way might be to write a custom extractor that extends com.tangosol.util.extractor.AbstractExtractor and overrides extractFromEntry() to extract the collection of zip codes from a cached Entity (the value of the passed in Map.Entry). Then you could write a query using that extractor ...
ValueExtractor extractor = new CustomEntityZipExtractor();
Filter filter = new ContainsFilter(extractor, "123456");
Set entries = cache.entrySet(filter);Thanks

Query on using Collection object in Multithreading

All,
I have a query on multithreading, I have a collection object-eg. HashMap which needs to be shared
among threads, I my have 3 options
1st option is to synchronize the method which does some manipulation on the collection object,
2nd option is to hold a lock on that object like
synchronized(object){
//do some work
3rd option - to make use of class ConcurrentHashMap available in java.util.concurrent package; which claims to be
Thread safe but also says the following in the API - They do not throw ConcurrentModificationException. However,
iterators are designed to be used by only one thread at a time
My queston is - how do I choose between these 3?
I know the decison needs to be taken by keeping performance issue in mind and also the number of times the values in HashMap will be updated by the threads. Can some one explain to me when/under what circumstances do I use options 1 || 2 || 3

My application has actually gone live now - after doing some load/performance testing
and comming to the conclusion that performance is satisfactory [I am designing a SMS gateway
that receives/buffers/stores/sends SMS]
Initially I used Hashmap and a LinkedList to store objects in memory and I had a mixture
of places where some times I made the entire method that modifies the LinkedList & hashmap
synchronized and some places where I held a lock on the object alone (I wasnt too sure which to use where)
Then upon movin to 1.5 I rechanged the the data structure to use ConcurrentLinkedQueue & ConcurrenthashMap.
But i have places where I still hold synchronized locks over those objects (which i think is unnecessary and removing the locks may improve the performance)
So can i come to the conclusion that classes in java.util.concurrent are all threadsafe and we can stop holding locks on the objects and let java take care of itself [or should I still hold a lock when doing structural modification] [though the APi states that a oncurrentmodificationexception will not be thrown & iterators are designed to be used by only one thread at a time]

Collect metrics failed because 'Query Datacenter Managed Object Reference' is not executed

Hello,
This is my first post on this forum; I am working for a Cisco partner.
I am working on Tidal Enterprise Orchestrator 2.3.0.441 (hotfix1 and 2, content update 1), part of CIAC starter edition.
Scheduled Collect metrics failed in 'vSphere Datacenter Sync' and in 'vSphere Cluster Data Sync' parts
Problem is at the level of 'Query Datacenter Managed Object Reference'
Input is Datacenter name (well defined, value is not '*'), but this box is not executed (stay white). Next box : 'Set Datacenter MOR' define a variable with value 'Datacenter-' instead of 'Datacenter-[output of Query Datacenter Managed Object Reference]. And finally 'Create Cluster table" failed because a root element is missing (the datacenter name)
So my question is why 'Query Datacenter Managed Object Reference' is not executed ?
I change nothing in the workflow, and Datacenter is normally well defined.
thank you for your help,
Cheers,
Nicolas

This particular utility workflow is set to not-archive completed instances.
This means that, after it finishes, it is not saved to the database and you can't see the runtime information. It improves performance and saves database space, but does make troubleshooting a little more roundabout.
You'll want to turn on archiving temporarily to see what the error message is. Open the process, go to the Options tab, and check the "Archive completed instances" box.

Delay when querying from CUBE_TABLE object, what is it?

Hi Guys,
We are using Oracle OLAP 11.2.0.2.0 with an 11g Cube, 7 Dimensions, Compressed and partitioned by Month.
We have run into a performance issue when implementing OBIEE.
The main issue we have is a delay while drilling on a hierarchy. Users have been waiting 7-12 seconds per drill on a hierarchy, and the query is only returning a few cells of data. We have managed to isolate this to slow performing queries on CUBE_TABLE.
For example, the following query returns one cell of data:
SELECT FINSTMNT_VIEW.BASE, FINSTMNT_VIEW.REPORT_TYPE, FINSTMNT_VIEW.COMPANY, FINSTMNT_VIEW.SCENARIO, FINSTMNT_VIEW.PRODUCT, FINSTMNT_VIEW.ACCOUNT, FINSTMNT_VIEW.SITE, FINSTMNT_VIEW.TIME
FROM "SCHEMA1".FINSTMNT_VIEW FINSTMNT_VIEW
WHERE
FINSTMNT_VIEW.REPORT_TYPE IN ('MTD' )
AND FINSTMNT_VIEW.COMPANY IN ('E01' )
AND FINSTMNT_VIEW.SCENARIO IN ('ACTUAL' )
AND FINSTMNT_VIEW.PRODUCT IN ('PT' )
AND FINSTMNT_VIEW.ACCOUNT IN ('APBIT' )
AND FINSTMNT_VIEW.SITE IN ('C010885' )
AND FINSTMNT_VIEW.TIME IN ('JUN11' ) ;
1 Row selected in 4.524 Seconds
Note: FINSTMNT_VIEW is the automatically generated cube view.
CREATE OR REPLACE FORCE VIEW "SCHEMA1"."FINSTMNT_VIEW" ("BASE","REPORT_TYPE", "COMPANY", "SCENARIO", "PRODUCT", "ACCOUNT", "SITE", "TIME")
AS
SELECT "BASE", "REPORT_TYPE", "COMPANY", "SCENARIO", "PRODUCT", "ACCOUNT", "SITE", "TIME"
FROM TABLE(CUBE_TABLE('"SCHEMA1"."FINSTMNT"') ) ;
If we increase the amount of data returned by adding to the query, it only increased the query time by .4 seconds
SELECT FINSTMNT_VIEW.BASE, FINSTMNT_VIEW.REPORT_TYPE, FINSTMNT_VIEW.COMPANY, FINSTMNT_VIEW.SCENARIO, FINSTMNT_VIEW.PRODUCT, FINSTMNT_VIEW.ACCOUNT, FINSTMNT_VIEW.SITE, FINSTMNT_VIEW.TIME
FROM "SCHEMA1".FINSTMNT_VIEW FINSTMNT_VIEW
WHERE
FINSTMNT_VIEW.REPORT_TYPE IN ('MTD' )
AND FINSTMNT_VIEW.COMPANY IN ('E01' )
AND FINSTMNT_VIEW.SCENARIO IN ('ACTUAL' )
AND FINSTMNT_VIEW.PRODUCT IN ('PT' )
AND FINSTMNT_VIEW.ACCOUNT IN ('APBIT' )
AND FINSTMNT_VIEW.SITE IN ('C010885', 'C010886', 'C010891', 'C010892', 'C010887', 'C010888', 'C010897', 'C010893', 'C010890', 'C010894', 'C010896', 'C010899' )
AND FINSTMNT_VIEW.TIME IN ('JUN11' ) ;
12 rows selected - In 4.977 Seconds
If we increase the data returned even more:
SELECT FINSTMNT_VIEW.BASE, FINSTMNT_VIEW.REPORT_TYPE, FINSTMNT_VIEW.COMPANY, FINSTMNT_VIEW.SCENARIO, FINSTMNT_VIEW.PRODUCT, FINSTMNT_VIEW.ACCOUNT, FINSTMNT_VIEW.SITE, FINSTMNT_VIEW.TIME
FROM "SCHEMA1".FINSTMNT_VIEW FINSTMNT_VIEW
WHERE
FINSTMNT_VIEW.REPORT_TYPE IN ('MTD' )
AND FINSTMNT_VIEW.COMPANY IN ('ET', 'E01', 'E02', 'E03', 'E04' )
AND FINSTMNT_VIEW.SCENARIO IN ('ACTUAL' )
AND FINSTMNT_VIEW.PRODUCT IN ('PT', 'P00' )
AND FINSTMNT_VIEW.ACCOUNT IN ('APBIT' )
AND FINSTMNT_VIEW.SITE IN ('C010885', 'C010886', 'C010891', 'C010892', 'C010887', 'C010888', 'C010897', 'C010893', 'C010890', 'C010894', 'C010896', 'C010899' )
AND FINSTMNT_VIEW.TIME IN ('JUN11', 'JUL11', 'AUG11', 'SEP11', 'OCT11', 'NOV11', 'DEC11', 'JAN12') ;
118 rows selected - In 14.213 Seconds
If we take the time for each query and divide by the number of rows, we can see that querying more data results in a much more efficient query:
Time/Rows returned:
1 Row - 4.524
12 Rows - 0.4147
118 Rows - 0.120449153
It seems like there is an initial delay of approx 4 seconds when querying the CUBE_TABLE object. Using AWM to query the same data using LIMIT and RPR is almost instantaneous...
Can anyone explain what this delay is, and if there is any way to optimise the query?
Could it be the AW getting attached before each query?
Big thanks to anyone that can help!

Thanks Nasar,
I have run a number of queries with logging enabled, the things you mentioned all look good:

Selection filter: FILTER_LIMITS_FAST     7
ROWS_FAILED_FILTER     0
ROWS_RETURNED     1
Predicates: 7 pruned out of 7 predicates
The longest action I have seen in the log is the PAGING operation... but I do not see this on all queries.

What is strange is that the cube operation log does not account for all of the query time. For example:
SELECT "BASE_LVL" FROM TABLE(CUBE_TABLE('"EXAMPLE"."FINSTMNT"'))
WHERE
"RPT_TYPE" = 'MTD' AND
"ENTITY" = 'ET' AND
"SCENARIO" = 'ACTUAL' AND
"PRODUCT" = 'PT' AND
"GL_ACCOUNT" = 'APBIT' AND
"CENTRE" = 'TOTAL' AND
"TIME" = 'YR09';
This query returns in 6.006 seconds using SQL Developer, if I then take the CUBE_OPERATION_LOG for this query and subtract the start time from the end time, I only get 1.67 seconds. This leaves 4.3 seconds unaccounted for... This is the same with the my other queries, see actual time and logged time below:
Query     Actual     Logged      Variance
S3     6.006     1.67     4.336
L1     18.128     13.776     4.352

S2     5.882     1.575     4.307
Any ideas on what this could be or how I can capture this 4.3 second overhead?
Your help has been greatly appreciated.

Is it possible the query in view object is dynamic?

Is it possible the query in view object is dynamic?
Generally, make the column list dynamic.
I think this is related to whether view object can be assembled at runtime based on a dynamic cursor in a procedure?
I ask this because I would like to know how we can use OA framework to simulate crosstab workbook in Discoverer?
Anybody has some clues, please advise.
Thanks.

Hi Shay,
Let me tell you briefly... I am sending input as customerId,customerNumber,CustomerName to the web service, if the record is available i am getting the response and i am displaying those records on page as a table. Now when i click a row i need to populate another table with all sale orders of that customer. From webservice datacontrol i have only customer object, I dont have Sales Order Object. For this i need master detail relation. In this case how to proceed. Thats why i am thinking to create a vO and EO object for sales orders table and i want to create view link for this sales order and customers. As i don't have customer VO and EO object to create view link.

How to build sql query for view object at run time

Hi,
I have a LOV on my form that is created from a view object.
View object is read-only and is created from a SQL query.
SQL query consists of few input parameters and table joins.
My scenario is such that if input parameters are passed, i have to join extra tables, otherwise, only one table can fetch the results I need.
Can anyone please suggest, how I can solve this? I want to build the query for view object at run time based on the values passed to input parameters.
Thanks
Srikanth Addanki

As I understand you want to change the query at run time.
If this is what you want, you can use setQuery Method then use executeQuery.

Query based collections SCCM 2012 R2

Hi to everyone. Is there any book or other material needed to master process of creating query-based collections? It is done using WQL not T-SQL so it is a little bit tricky, not only syntax itself but also classes where particular information useful to
create custom query-based collection can be found. I used WQL before only to create WMI filters for some GPOs in order to narrow their scope e.g. only to Windows 7 workstations in domain. These WMI filters were usually created
with one short WQL line, it was very simple WQL query. Bare in mind all classes that exist in SCCM database googling can be useful to solve some problems but it would be better to have some book and to master creation of query-based
collections.

JPA query by entity/object ?

I am trying to write an abstract API which dynamically assigns any Entity Class that needs to be persisted and retrieved using the Entity Manager.
Saving into the database is not a problem, I just do entityManager.save(Class) and it works for any class that needs to be persisted.
However, when querying for the object based upon the attributes, I want to avoid naming particular attributes and want to use the Entity class's attributes against itself for querying.
For example, the client program will say something like this to query by name and age of a Person:
-------calling (client) program: ---
Person p = << get from UI, not saved yet, no Id but has all other attributes like name and age etc. >>
List<Person> persons = dao.getAllThatMatch(p);
--- end client Program --
--- DAO class ---
List<T> getAllThatMatch(T t) { //note that expectation is that returned is a list of Object which is the same as the querying object
List<T> entityList = em.someFinderMethod(t);
//the someFinderMethod method should automatically query for all Person objects that match the attributes provided by the object of Person supplied as criteria
//NOTE: there is no attribute mentioned extensively like name, age etc.
return entityList ;
-- end DAO class --

Query by example is not included in the JPA standard, but it is possible to do with EclipseLink.
See http://wiki.eclipse.org/EclipseLink/Examples/JPA/ORMQueries#Query_By_Example
for how to use query by example with native EclipseLink queries. To execute a native query through JPA, you will need to call createQuery(DatabaseQuery query) on the org.eclipse.persistence.jpa;JpaEntityManager obtained from the javax.persistence.EntityManager instance by calling getDelegate() or unwrap.

Problems with query in view object

I have create query form view object that is render on a jsp. The dynamic generate query leaves out "'" single quotes on string 'not assigned' which is selected from a lov.
Does anyone no how I might fix this?
Thanks.

Greg:
Please provide further details. How are you creating the dynamically generated query? Could you show the original query vs. what is executed?

How do I query changed view object attribute in another view object

Jdeveloper 10.1.3.4
My requirement is that I want to be able to query a view object (based on entity) on a non-key attribute where the value I am searching on may either be in the database on an existing record or, have just been recorded by updating a different view object based on the same entity (and yet to be committed).
When querying the second view object for a value just updated via a different view object, the second view object always returns no rows. I had expected the process to be :
EntityA
ViewObjectA based on EntityA
ViewObjectB based on EntityA
ViewObjectA - query row with key = 123. update attribute Y with value 456 (attribute Y in database null). Entity cache for EntityA, key 123, atttribute Y updated with value 456
ViewObjectB - query row with attribute = Y. expect record in EntityA cache just updated to be returned. Instead, nothing is returned
Here is the code I was using (where RandScheduleEdit and RandScheduleSearch are identical view objects based on entity object RandSchedule)
public static void main(String[] args) {
    String        amDef = "test.cache.model.AppModule";
    String        config = "AppModuleLocal";
    ApplicationModule am = Configuration.createRootApplicationModule(amDef,config);
    ViewObject rsEdit = am.findViewObject("RandScheduleEdit");
    Key rsKey = new Key(new Object[]{40});
    Row[] rsEditRows = rsEdit.findByKey(rsKey,1);
    Row rsEditRow = rsEditRows[0];
    rsEditRow.setAttribute("SId", new Number(7827));
    ViewObject rsSearch = am.findViewObject("RandScheduleSearch");
    rsSearch.setWhereClause("S_ID = :SId");
    rsSearch.defineNamedWhereClauseParam("SId", null, null);
    rsSearch.setNamedWhereClauseParam("SId",new Number(7827));
    rsSearch.executeQuery();
    Row rsSearchRow = rsSearch.first();
    Configuration.releaseRootApplicationModule(am, true);
}Why does rsSearch not find the record S_ID = 7827 ? It seems to only be querying new records in the database and ignoring the cached record just updated ?
Any help greatly appreciated.
Cheers,
Brent

rsSearch.setNamedWhereClauseParam("SId",new Number(7827));This might help:
rsSearch.setQueryMode(ViewObject.QUERY_MODE_SCAN_ENTITY_ROWS);
rsSearch.executeQuery();

Problems persisting the collection object in Web dynpro context

Hello,
I am trying to bind a Instance of hashtable (java.util.Hashtable) in the context.
I instantiate a hashtable and bind it to the context for the first time, when i fetch it, it returns null. Is it possible to store a collection object in the context ??
I am a newbie with Web dynpro - java. Sorry if it is a repeated question.
Awaiting the suggestions.
Thanks in advance,

Hi Harish,
Welcome to SDN. Yes, it is possible to bind a collection object in the context.

Odd QoQ issue when querying Solr collection

Hello, everyone.
I've got a query of query issue that has me stumped. Maybe I'm just missing something very simple, but this has got me really confuzzed.
I have a Solr collection that is indexing a few tables in an Oracle database. Let's call it "hdq", for this discussion.
I wrote a semi-complex query of related tables from which the CFINDEX is using to index the data. This is working just fine.
I created the Solr collection in the CF9 CFAdmin, and am using the following to index with:
<cfindex action="refresh" collection="hdq" key="QUESTION_ID" type="custom" title="QUESTION_TITLE" query="search_questions" body="QUESTION_TX,QUESTION_TITLE,CATEGORY_NM,TAG_NM,ANSWER_TITLE,ANSWER_TX"
custom1="QUESTION_STATUS" custom2="TAG_NM" custom3="QUESTION_STATUS" custom4="QUESTION_TYPE" category="CATEGORY_NM">
Then I do a CFSEARCH and name it "hd_questions". Again, so far, so good, no problems.
If I do a CFDUMP of "hd_questions", one of the columns is KEY (which is QUESTION_ID in the database.) If I CFOUTPUT the collection, KEY is there.
If I QoQ the CFSEARCH of the collection and use SELECT custom3, score, summary, context, key FROM hd_questions, I get an error message that
Encountered "key. Incorrect Select List, Incorrect select column,
.. then it gives the line number of the page that produced the error, and
<cfquery dbtype="query" name="hd_results">
Am I missing something simple, here? KEY is in the collection, I can see it in CFDUMP, I can see it in CFOUTPUT. But if I query the collection and try to select KEY, there is an error.
Any thoughts/ideas?
Thank you,
^_^

Key is a reserved word in Coldfusion, so can't be used directly in a QoQ without escaping it. Try wrapping it in [ ] instead, i.e. [key]
It may also help to give it an alias too, e.g. SELECT [key] AS someKey
See the list of reserved words here: http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec173d0-7f ff.html and the QoQ guide to using reserved words here: http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec0e4fd -7ff0.html#WSc3ff6d0ea77859461172e0811cbec22c24-7008

How do you query a collection in a Standard Tabular Form?

I'm adding validation to a Standard Tabular form, and would like to use the values of attributes in the collection as part of the validation. To do this, I want to query the collection in the Tabular form to find the current values of the attributes. Is it possible to query collection values in a Standard Tabular form? If so, how do you find the name of your collection that is generated by the wizard? I am query against the APEX_COLLECTIONS view and getting 'no data found'.
Thanks,
James

You cannot access any COLLECTIONS here. What you need , I think is this http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21676/apex_app.htm#AEAPI215.
For more details , see examples here http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21676/apex_item.htm
