Query memory use of a HashMap at runtime? Overall JVM Memory Use?
Is there any way that my application can query the deep memory usage (including keys/values) of a HashMap instance at runtime?
Is there any way that I can query overall memory use of the entire app or JVM through code?
Thanks!
You can use the memory profiler in JDeveloper to test this:

DB Adapter Query - Polling using nested select
When polling a table to initiate a BPEL process, can I use a nested select in the expression.
The visual expression builder does not currently support this so you need to specify the raw sql directly.
If you use the DeletePollingStrategy there is a way you can specify the exact sql string for both the 'select' and the after read 'delete'. So if you write the where clause yourself it can contain nested selects.
This is the readme from the new PureSQLSelect database adapter sample. Also you may want to look at the PureSQLPolling sample.
This sample shows you how you can bypass the designer's visual where clause builder to specify arbitrarily complex sql strings for your selects.
Like the other samples, this sample uses the basic Movies schema.
The Steps:
Create a basic select. Made sure it has the same name and number of input parameters as you will need for your sql string. In this case create a single input parameter and call it 'genre_param'.
Create a trivial where clause in the wizard expression builder using genre_param. I.e. genre.like(genre_param)
Ideally run the sample once just to make sure everything else works and to get a template SQL. The select ... FROM ... part will be the same.
Open the toplink_mappings.xml file. Look for an element called <database-query>. There will likely only be one. A sample is presented here:

Gotchas:
The tempation to start writing pure sql may be terrible to some, but it was intentionally left out of the wizard for good reasons. Please be wary of the following when specifying pure sql:
-There is a way to set the pure sql string in the Mapping Workbench, but when you edit the partnerlink to refresh the toplink_mappings.xml you may get an exception due to the query being in a pure sql format. For this reason you need to manually edit the toplink_mappings.xml, and again every time your run the wizard and hit finish after that.
-The #genre_param is a TopLink convention for writing a sql string which still takes parameters. At runtime if you enter 'Action' in the bpel console, you will see this sql:
SELECT DELETED, DIRECTOR, GENRE, LAST_UPDATED, RATED, RATING, RELEASE_DATE, RUN_TIME, SEQUENCENO, STARRING, STATUS, SYNOPSIS, TITLE, TOTAL_GROSS, VIEWER_RATING FROM SYSTEM.MOVIES WHERE (GENRE LIKE ?)
bind => [Action]
The #genre_param gets replaced with the value of the input parameter genre_param.
-When specifying pure sql you should be aware of the following:
-maintenance issues
-loss of database platform independence
-The sql needs to conform with the way TopLink works. It is recommended that you do not change the SELECT ... FROM ... part of the query. TopLink's design is to read from one table at a time. If an Employee has an Address, then the Address is read with a hidden relationship query. There are two advanced TopLink features which optimize reading from multiple tables, called joinedAttribute and batchAttribute reading, but the combination of these features with raw sql was not explored here. So to avoid danger you can only really affect the top level query, and only rewrite the where clause.
-The pure sql route does not interact with most TopLink features, especially batch reading (on by default), and can not be combined with the following:
-LogicalDeletePollingStrategy
-SequencingPollingStrategy (LastUpdated, LastReadId, File)
These features extend the selection criteria at runtime. -
Improving a simple select query, which uses all rows.

How can i fetch records from 3 tables in a single query without using join
Hi.
Can any body please tell me <b>How can i fetch records from 3 tables with a single query without using joins</b>
Thanx
prabhuduttaHi Prabgudutta,
We can fetch the data by using the views concept.
Go throuth this info we can know the how to create view and same like database table only we can fetch the data.
Views conatin the data at runtime only.
Four different view types are supported. These differ in the
way in which the view is implemented and in the methods
permitted for accessing the view data.
Database views are implemented with an equivalent view on
the database.
Projection views are used to hide fields of a table (only
projection).
Help views can be used as selection method in search helps.
Maintenance views permit you to maintain the data
distributed
on several tables for one application object at one time.
step by step creation of Maintenance view:
With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.
It can be set in transaction SE11 - Tools - Table maintenance generator.
Table maintanance Generator is used to manually input values using transaction sm30
follow below steps
1) go to se11 check table maintanance check box under attributes tab
2) utilities-table maintanance Generator-> create function group and assign it under
function group input box. Also assign authorization group default &NC& .
3) select standard recording routine radio in table table mainitainence generator to move table
contents to quality and production by assigning it to request.
4) select maintaience type as single step.
5) maintainence screen as system generated numbers this dialog box appears when you click on create button
6) save and activate table
One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.
SM30 is used for table maintenance(addition or deletion of records),
For all the tables in SE11 for which Table maintenance is selected , they can be maintained in SM30
Sm30 is used to maintain the table ,i.e to delete ,insert or modify the field values and all..
It creates the maintenance screen for u for the aprticular table as the maintenance is not allowed for the table..
In the SE11 delivery and maintenance tab, keep the maintenance allowed..
Then come to the SM30 and then enter the table name and press maintain..,
Give the authorization group if necessary and give the function group and then select maintenance type as one step and give the screen numbers as system specified..
Then create,,,
Then u will able to see the maintenance view for the table in which u can able to insert and delete the table values...
We use SM30 transaction for entering values into any DB table.
First we create a table in SE11 and create the table maintenance generator for that Table using (utilities-> table maintenance generator) and create it.
Then it will create a View.
After that from SM30, enter the table name and Maintain, create new entries, change the existing entries for that table.
Hope this resolves your query.
Reward all the helpful answers.

Hi,
how to check Query is used or not
Thanks,Hi ,
Go to SE11 and check table RSRREPDIR .Here give your query name in COMPID and you will get
LASTUSER Last Changed By
MODTIME Last Change to Definition
REPTIME Last Change of Query Runtime Object
GEN1TIME Query Generation Time
I think this will solve your purpose .

I am using BIApplicationFrame ui element for this.
I set the template id in template property of BIApplicationFrame.
I have to execute a query of this template.
So i selected the option 'query' of dataProviderStateType property.

Can I refactor this query to use an index more efficiently?
I have a members table with fields such as id, last name, first name, address, join date, etc.
I have a unique index defined on (last_name, join_date, id).
This query will use the index for a range scan, no sort required since the index will be in order for that range ('Smith'):
SELECT members.*
FROM members
WHERE last_name = 'Smith'
ORDER BY joindate, idIs there any way I can get something like the following to use the index (with no sort) as well:
SELECT members.*
FROM members
WHERE last_name like 'S%'
ORDER BY joindate, idI understand the difficulty is probably; even if it does a range scan on every last name 'S%' (assuming it can?), they're not necessarily in order. Case in point:
Last_Name: JoinDate:
Smith 2/5/2010
Smuckers 1/10/2010An index range scan of 'S%' would return them in the above order, which is not ordered by joindate.
So is there any way I can refactor this (query or index) such that the index can be range scanned (using LIKE 'x%') and return rows in the correct order without performing a sort? Or is that simply not possible?xaeryan wrote:

The db engine accesses contiguous index entries and then uses the ROWID values in the index to retrieve the table rows. -

Unable to parse query when using dblink in forms 4.5
Hi,
I have created a query that uses a DBlink because I need to do query on a table located on another dbase. I've used the query on creating my report using Reports 6i. The report needs to be called from a menu on our system, which was developed under Developer 2000 (forms 4.5). The problem is, when I tried to access the report from the menu, it returns the error 'unable to parse query'. What I did after getting error was to create a dummy module using Forms 6i, and call my report from there. It worked fine.
By the way, the table that I'm accessing using the dblink is under Oracle 9i dbase, and the dbase of the system that I've been working at is Oracle 8i.
I don't have any idea on what's causing this error. Is there a compatibility issue when using a dblink located in Oracle 9i database with forms 4.5?
Thanks!Hello,
Not sure if it is the good answer, but I know that Forms does not recognize dblink and owner.object syntax. You have to create a simple synomym that point to the distant object and use this synonym within Forms.

KabeerI currently use parameters, and they are passed from the form to the report. Report is then generated based on a function returning ‘strongly typed’ cursor. The ‘strongly typed’ cursor in my case returns a record consisting of an orderly collection of fields.
This collection of fields is returned by another function that relies on the IF … THEN logic.
However, the number of IF ... THEN statements is quite large (currently 64 covering all possible combinations of 6 parameters available in the form).
I would like to avoid the large number of IF … THEN statements, and hope that there is a way of passing a string to a query, where the Dynamic SQL would in Select close and Where close reflect parameters passed by the form.
In addition to this I would like to avoid creating and populating a table or a view dedicated to the report, because this may lead to a conflict in case of multiple users concurrently generating reports with different choice of parameters.

How to find out Query last used by whom
Dear All,
Can any one tell me that "How to find out the Query last used by whom. I have already searched in SDN but no luck. In my system BW Stats are not installed and I have already checked the below tables.
RSZELTDIR - Directory of the reporting component elements
RSZELTTXT - Texts of reporting component elements
RSZELTXREF - Directory of query element references
RSRREPDIR - Directory of all reports (Query GENUNIID)
RSZCOMPDIR - Directory of reporting components
RSZRANGE - Selection specification for an element
RSZSELECT - Selection properties of an element
RSZELTDIR - Directory of the reporting component elements
RSZCOMPIC - Assignment reuseable component <-> InfoCube
RSZELTPRIO - Priorities with element collisions
RSZELTPROP - Element properties (settings)
RSZELTATTR - Attribute selection per dimension element
RSZCALC - Definition of a formula element
RSZCEL - Query Designer: Directory of Cells
RSZGLOBV - Global Variables in Reporting
RSZCHANGES Change history of reporting components
I am able to find out the Date and time but not the user name. So could you please help on this.
Regards
Sankari think u have missed it.
RSZCOMPDIR IS THE ONLY TABLE WHICH PROVIDES THE DATA.
ENTER TECHNICAL QUERY Name in RSZCOMPDIR-COMPID.
RSZCOMPDIR-TSTNAM gives you the user id of sap bw user who made the change.
RSZCOMPDIR-TSTPDAT gives you date on which change was made .
RSZCOMPDIR-TSTPTIM gives you timestamp on which change was made .
all users details can be obtained from TCODE SU01 where you need to enter sap user id.
You can also get user name( description) by using tcode SE09 and entering above sap user id. -
Combine two reports in query designer using key figure with sap exit
Hi experts,
i want to combine two reports in query designer using key figure with sap exit
in the report 1 key figure calculation based on the open on key date(0P_DATE_OPEN)
to calculate due and not due in two columns
in report 2 key figure calculate in the time zones using given in variable Grid Width (0DPM_BV0) like due in 1 to 30 days, 31 to 60 days...the due amount based on the open on key date(0P_DATE_OPEN)
to calculate in 1-30, 31-60, 61-90, 91-120, 121-150 and >150 days in 6 columns
now i have requirement like this
not due, 1-30, 31-60, >60, due,1-30, 31-60, >60 in 8 columns
or
not due, due, 1-30, 31-60, 61-90, 91-120, 121-150 and >150 in 8 col
thank youHi Dirk,
you perhaps know my requirement,
for the management to make used in one report,
we have in reporting finacials Ehp3.
Vendor Due Date Analysis - which show due, not due
Vendor Overdue Analysis - show only due and analysis in time grid frame
i want to combine in one report that show NOT DUE, DUE, DUE time frames in grid.

Invalid column name in query string - using Format function
In my post just before this one the problem was solved for writing a query string using a date range. The rest of the query string includes the same date field (Call_Date) but formatted as 'MMM-YY'. I get an invalid column name error when I add this field to the query string. Here is the rest of the query string:
strSql = "SELECT Format(CALL_DATE,'mmm-yy'), " _
& "HOME_REGION FROM CCC2.CASE_EPRP " _
& "WHERE (HOME_REGION = 'NCR') AND " _
"(CALL_DATE >= to_date( '1/1/2002', 'MM/DD/YYYY' )" _
& "AND CALL_DATE <= to_date( '2/28/2003', 'MM/DD/YYYY' ))"
In the Access Query tool I can include this field
Format(CALL_DATE,'mmm-yy')
and the query runs fine (I just need to make it dynamic using ADO). But in my ADO query string above, I get the invalid column name error. Is there a way I can include
Format(CALL_DATE,'mmm-yy')
in my ADO query string? I appologize for not being more familiar with Oracle Sql. Any help greatly appreciated.
Thanks again,
RichThank you very much for your reply. I think I'm getting closer to the solution. Just I got an error message
"date format not recognized"
when I add "to_char( call_date, 'mmm-yy' )" to the query string. I tried using all uppercase, but that did not make a difference. Do I need to use to_date inside the to_char maybe?
to_char(to_date(call_date, 'mmm/yy'), 'mmm-yy')
Thanks again for your help.

Needs help to retrive the last row in a select query without using rownum
Hi ,
i need to retrive the last row from the select sub query without using rownum.
is there any other way to retrive the last row other than the below query.
is that the ROWNUM=1 will always retrive the 1 row of the select query ?
select from*
*(select ename from employee where dept_id=5 order by desc) where rownum=1;*
Please advise.
thanks for your help advance,
regards,

Actually my problem is ithat while selecting the parents hiearchy of the child data using
CONNECT BY PRIOIR query
I need the immediate parent of my child data.
For example my connect BY query returns
AAA --- ROOT
BBB --PARENT -2
CCC --PARENT-1
DDD IS my input child to the connect by query
Immediate parent of my child data "DDD" ---> CCC(parent -1)
i want the data "CCC" from the select query,for that i am taking the last row of the query with rownum.
I got to hear that using ROWNUM to retrive the data will leads to some problem.It is a like a magic number.I am not sure what the problem will be.
So confusing with using this rownum in my query.
Please advice!!!It's not quite clear what you're wanting, but perhaps this may help?
you can select the PRIOR values to get the parent details if you want...

SQL Query not using Composite Index
Hi,
Please look at the below query:
SELECT pde.participant_uid
,pde.award_code
,pde.award_type
,SUM(decode(pde.distribution_type
,'FORFEITURE'
,pde.forfeited_quantity *
pde.sold_price * cc.rate
,pde.distributed_quantity *
pde.sold_price * cc.rate)) AS gross_Amt_pref_Curr
FROM part_distribution_exec pde
,currency_conversion cc
,currency off_curr
WHERE pde.participant_uid = 4105
AND off_curr.currency_iso_code =
pde.offering_currency_iso_code
AND cc.from_currency_uid = off_curr.currency_uid
AND cc.to_currency_uid = 1
AND cc.latest_flag = 'Y'
GROUP BY pde.participant_uid
,pde.award_code
,pde.award_type
In oracle 9i, i"ve executed this above query, it takes 6 seconds and the cost is 616, this is due to non usage of the composite index, Currency_conversion_idx(From_currency_uid, To_currency_uid, Latest_flag). I wonder why this index is not used while executing the above query. So, I've dropped the index and recreated it. Now, the query is using this index. After inserting many rows or say in 1 days time, if the same query is executed, again the query is not using the index. So everyday, the index should be dropped and recreated.
I don't want this drop and recreation of index daily, I need a permanent solution for this.
Can anyone tell me, Why this index goes stale after a period of time???? Please take some time and Solve this issue.

This is Sankar here. Thankyou for your reply.

Hi guys,
I'm trying to logical database MSM to report on material master but for some reason the following message appears:
The query specifications cannot be used to generate a list,
i.e. the query will probably not return the list you desire.
If you still want to execute the query, please use the
"Generate" function.
Errors are like this :
Fields from parallel tables within a line
Line: 01
Field: Post to Inspection Stock
(MARCV-INSMK, table MARCV)
Field: Item category group from material master
(MVKE-MTPOS, table MVKE)
Any idea what is the reason why this happens?
Thanks and regards
Stefan
Edited by: Stefan Tzandev on Sep 15, 2008 1:44 PMHey Stefan,
I know this is a long shot, but were you able to figure it out. I am having the same problem as we speak. I tried rearanging the fields according to the heirchy, it now works, but has a really bad output. Hope to hear from you.
