Dynamic Buffering Based on Bandwidth and Datarate

I'm trying to determine an initial value for NetStream.bufferTime based on the client's calculated bandwidth and the video's bitrate.
As far as I can tell you can't do this, because you must have an initial buffer set BEFORE you call NetStream.play() (or use the default 2 seconds) and FMS does not call NetStream.onMetaData, where one would normally find the videodatarate, until after NetStream.play() is called.
Even if you modify NetStream.bufferTime during the onMetaData call back it doesn't effect when the video starts playing or when the NetStatus event registers "NetStatus.Buffer.Full".
Therefore my question is:
How do I find the Video Data Rate BEFORE I call NetStream.play?
-Or-
How do how do I reset the initial bufferTime before acctual play back begins and the NetStatus event fires with "NetStatus.Buffer.Full"

I think you are right. Without playing the stream you cant decide it datarate.

Dynamic domain-based entity creation and relation to base entity

Hi everyone -
My first post here... I have a base entity (PROJECT) with an attribute called RecordType (a domain-based attribute). Depending on the value of RecordType, the business wants to use that result set as input for another reference entity, and then
relate them together in a possible {one|many}-to-many relationship. For example:
If RecordType = Strategy, then there is a need to create a separate entity called STRATEGY with the results of that filter. The PROJECT entity and STRATEGY now need to be related together in a PROJECT_STRATEGY relationship table.
There seem to be a couple of options, but none are elegant, and some simply don't work:
Option #1 (doesn't work): I create the relationship table (PROJECT_STRATEGY) with a domain-based attribute of the PROJECT entity and a second domain-based attribute of the PROJECT entity (but called Strategy), and then try to create a business
rule that limits the selection of the second domain-based attribute by RecordType. MDS tells me I can't use a domain-based attribute in the business rule.
Option #2: I create a SQL Server view called STRATEGY (which is a query based on the PROJECT entity - "where RecordType = 'Strategy') and use that as the reference set. However, there is now no way to utilize that result set inside MDS.
In other words, I cannot use it as a domain-based attribute in the PROJECT_STRATEGY relationship table. This means that an external system/UI would need to enable the relationship selection and write back into the PROJECT_STRATEGY relationship table
inside MDS.
Option #3: I create a STRATEGY entity that is auto-updated (via SQL Server job) every 10 minutes or so from the PROJECT entity (can't figure out how to load a reference entity based on a result set from an existing entity). This allows me to create
two domain-based attributes in the PROJECT_STRATEGY table (as described in Option #1), but is also what I call a non-standard customization, so I have been reticent to go this route.
So, my questions/comments are:
Is there any way to make Option #1 work (using business rules)?
Option #2: Our development team doesn't want to create a separate system/UI to relate the list of PROJECTs to the list of STRATEGYs and then write them back into the PROJECT_STRATEGY relationship table. This also limits the ability to maintain the
PROJECT_STRATEGY table inside MDS since the STRATEGY domain-based attribute would become a free-form attribute at that point. Is there any way to register a view as a reference entity?
Should I explore Option #3? Non-standard, non-native functionality introduced into MDS (any system, really) is something I wanted to avoid, but only from a purity and possible upgrade standpoint. Should I get over this?
I have looked at derived and explicit hierarchies for the PROJECT entity, but they do not seem to apply in the scenario above.
Has anyone tried to create {one|many}-to-many relationships between a base entity and a subset of that base entity without resorting to non-standard customizations within MDS? Is this as bizarre as it sounds?
Any help would be greatly appreciated.
Thanks.

Dynamic report based on Parameters and a Button

Trying to make a dynmic report based on Parameters entered.Wanted to refresh report when i click on a button say "OK" based on parameters entered.
(1) created 2 text boxes -- Parameters --One date and other employee No
(2) on the same page i created a report-region which id dynamic "PL/SQL Function Returning SQL Query "
In this query i am using the parameters created in step1
(3) Then i created a Button say "OK" .
(4) When i enter parameters and then press OK i need to refresh my report in region defined in step2
This refresh is not happening .
Not sure what is missing
I tried using branching it didn't work
In the dynamic region it shows "No data found"
Please help

sachin
1) make sure there is no Optional Redirect defined on the OK button. That is, make sure the page is really submitted.
2) in the PL/SQL body generating the query, print out the query using htp.p() so you get to see it and test it.
3) use the session state link in the developer toolbar in conjunction with the technique in step 2) to debug your query
Maybe the report region is refreshing, but it just isn't returning any results.

Hyperion Planning dynamic forms based on start and end date across years

Hi All,
I have a requirement where i need to be able to view a form showing periods across years that are dynamically built depending on the start and end dates. If i have a start date of 01/11/2009 and an end date of 31/7/2013 i want to be able to view a form that shows all of the periods (Jan,Feb etc) in a form that is driven by these dates, in addition it will need to show the actual scenario up to the current month and the forecast from the current month to the end date. So basically if a user inputs the start and end dates the form will display the relevant periods driven by these dates.
Any tips very much appreciated!

Hello,
This is difficult to realize, but you can get quite far with a workaround. The first question is, where do you want to input your selection of time periods? Assuming you have a webform with the complete timeline in months and years and you type in the start period and end period.
Webforms have the option to suppress rows and columns.
This can be extended with option of empty cells or not empty cells.
You will need to apply your creativity on this.
Put every month-year combination in a column and add the suppression.
Calculate the timeline between start period and end period with a dummy member, so data exists for these and columns will show.
Maybe you will need to copy the required timeline into a separate version for this, to avoid having periods which were outside the selection and still have data.
I hope these hints help a bit in this challenge.

FLVPlayback dynamic buffering

This is a multi-part request.
I'm looking for a way to dynamically buffer progressive video
using the AS3 FLVPlayback component. I am doing bandwidth detection
using a SMIL file. I would like to set buffer via the clients
bandwidth. I do not have FMS.
I've "heard" that the AS3 FLVPlayback component has this
built in. That is, only starts playing after it concludes what it
will take to play the video from start to end. I'm having a hard
time verifying this through documentation.
So, I'm looking for help on dynamic buffering, and if anyone
knows if the AS3 FLVPlayback component offers this ability out of
the box.

I don't use FLVPlayback (I write my own players) but for sure
AS2 or AS3 the code you are trying to use is not good because it
doesn't use FLVPlayback.
There is an example in CS3/CS4 of using FLVPlayback.
Here is documentation for the componenet:

Hide multiple rows in a dynamic table based on the row value.

Hi,
I need to hide multiple rows in a dynamic table based on the specific value of that row.
I cant find the right expression to do that.
please help

Go to the Row Properties, and in the Visibility tab, you have "Show or hide based on an expression". You can use this to write an expression that resolves to true if the row should be hidden, false otherwise.
Additionally, in the Matrix properties you should take a look at the filters section, perhaps you can achieve what you wish to achieve through there by removing the unnecessary rows instead of just hiding them.
It's only so much I can help you with the limited information. If you require further help, please provide us with more information such as what data are you displaying, what's the criteria to hiding rows, etc...

Dynamic LOV based on Current user

How do i make a dynamic LOV based on the user id of the current user.
Also how to insert values from a form into a database
Can anyone please help me out.
Thanks

Use portal.wwctx_api.get_user to get the currently logged in userid.
The simplest example of a form manipulating data is to create the form based on a table. All DML works automagically. You can base your form on a procedure with dummy columns and do your own DML if you wish. Lots more flexibility that way...

Creating a dynamic lov based on a column

Hi,
I want to create a dynamic lov based on a column in a database-table.
Eg. the query
'select code, description from code_table'
is the contents of the column 'lov_query' in the table 'parameters'.
For every parameter there can be a different lov-query, but the result is always
two columns (code and description, number and name, etc.), exactly what you need to use in a lov.
I've written a (dbms_sql) function that takes the parameter-id and returns the lov_query.
create or replace function "GET_PMR_LOV"
(pmr_id in NUMBER)
return VARCHAR2
is
cur INTEGER := DBMS_SQL.OPEN_CURSOR;
fdbk INTEGER;
l_pmr_id NUMBER(9) := pmr_id;
l_stmnt VARCHAR2(2000);
begin
DBMS_SQL.PARSE
(cur, 'select pmr.lov_query from parameters pmr where pmr.ID ' || ' = 'L_PMR_ID', DBMS_SQL.NATIVE);
DBMS_SQL.BIND_VARIABLE (cur, 'L_PMR_ID', l_pmr_id);
DBMS_SQL.DEFINE_COLUMN (cur, 1, l_stmnt, 2000);
fdbk := DBMS_SQL.EXECUTE (cur);
fdbk := DBMS_SQL.FETCH_ROWS (cur);
IF fdbk > 0
THEN
DBMS_SQL.COLUMN_VALUE (cur, 1, l_stmnt);
return (l_stmnt);
ELSE
return null;
END IF;
DBMS_SQL.CLOSE_CURSOR (cur);
END;
But now I'm stuck on how to pass on this statement in HTMLDB
as an dynamic lov, I don't seem to be able to execute this statement
into the two display and return columns. Any ideas?

Hello again,
This lov is on an updatable report-column where the user has to make a choice from an non-named, popup and query-based lov. In the lov-query box I have just put:
"return get_pmr_lov(:p41_param_id)" (without the quotes ;-)
Here's my latest version plus an alternative, which both seem to work fine:
create or replace function "GET_PMR_LOV"
(pmr_id in NUMBER)
return VARCHAR2
is
cur INTEGER := DBMS_SQL.OPEN_CURSOR;
fdbk INTEGER;
l_pmr_id NUMBER(9) := pmr_id;
l_stmnt VARCHAR2(1000);
begin
DBMS_SQL.PARSE (cur, 'select pmr.lov_query from paramaters pmr where pmr.ID ' || '= :L_PMR_ID', DBMS_SQL.NATIVE);
DBMS_SQL.BIND_VARIABLE (cur, 'L_PMR_ID', l_pmr_id);
DBMS_SQL.DEFINE_COLUMN (cur, 1, l_stmnt, 1000);
fdbk := DBMS_SQL.EXECUTE (cur);
fdbk := DBMS_SQL.FETCH_ROWS (cur);
IF fdbk > 0 THEN
DBMS_SQL.COLUMN_VALUE (cur, 1, l_stmnt);
return (l_stmnt);
ELSE
return null;
END IF;
DBMS_SQL.CLOSE_CURSOR (cur);
END;
create or replace function "GET_PMR_LOV2"
(pmr_id in NUMBER)
return VARCHAR2
is
l_pmr_id NUMBER(9) := pmr_id;
l_stmnt VARCHAR2(1000);
BEGIN
EXECUTE IMMEDIATE 'select pmr.lov_query from parameters pmr where pmr.ID = :1'
INTO l_stmnt USING l_pmr_id;
return l_stmnt;
END;
The error-message remains the same, unable to bind :p41_param_id !

Hi Michelle,
          First of all Special thanks for your informative answers to my other forum questions. I really appreciate your help.
Coming back to this question I am still waiting for an answer. Please help. Note that my structure is not in a dictionary.
I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition
I have updated my code like the following and I am getting error:
TYPES: BEGIN OF t_type,
CARRID TYPE sflight-carrid,
CONNID TYPE sflight-connid,
END OF t_type.
Data: i_struc type table of t_type,
dyn_node type ref to if_wd_context_node,
rootnode_info type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
wa_node_att-name = 'CARRID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
insert wa_node_att into table i_node_att.
wa_node_att-name = 'CONNID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
attributes = i_node_att
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
But now I am getting the following error :

Dynamic Rule based implementation in PL/SQL

Hi,
We are trying to implement a dynamic rule based application in Oracle 9i. Its simple logic where we store expressions as case statments and actions seperated by commas as follows.
Rule: 'Age > 18 and Age <65'
True Action: 'Status = ''Valid'' , description = ''age in range'''
False Action: 'Status =''Invalid'', Description=''Age not in range'''
Where Age,Status, description are all part of one table.
One way of implementing this is fire rule for each record in the table and then based on true or false call action as update.
i.e
select (case when 'Age > 18 and Age <65' then 1 else 0 end) age_rule from tableX
(above query will in in a cursor xcur)
Then we search for
if age_rule = 1 then
update tablex set Status = ''Valid'' , description = ''age in range'' where id=xcur.id;
else
update tablex set Status =''Invalid'', Description=''Age not in range'' where id=xcur.id;
end if;
This method will result in very slow performance due to high i/o. We want to implement this in collection based method.
Any ideas on how to dynamically check rules and apply actions to collection without impact on performance. (we have nearly 3million rows and 80 rules to be applied)
Thanks in advance

Returning to your original question, first of all, there is a small flaw in the requirements, because if you apply all the rules to the same table/cols, than the table will have results of only last rule that was processed.
Suppose rule#1:
Rule: 'Age > 18 and Age <65'
True Action: 'Status = ''Valid'' , description = ''age in range'''
False Action: 'Status =''Invalid'', Description=''Age not in range'''
and Rule#2:
Rule: 'Name like ''A%'''
True Action: 'Status = 'Invalid'' , description = ''name begins with A'''
False Action: 'Status =''Invalid'', Description=''name not begins with A'''
Then after applying of rule#1 and rule#2, results of the rule#1 will be lost, because second rule will modify the results of the first rule.
Regarding to using collections instead of row by row processing, I think that a better approach would be to move that evaluating cursor inside an update statement, in my tests this considerably reduced processed block count and response time.
Regarding to the expression filter, even so, that you are not going to move to 10g, you still can test this feature and see how it is implemented, to get some ideas of how to better implement your solution. There is a nice paper http://www-db.cs.wisc.edu/cidr2003/program/p27.pdf that describes expression filter implementation.
Here is my example of two different methods for expression evaluation that I've benchmarked, first is similar to your original example and second is with expression evaluation moved inside an update clause.
-- fist create two tables rules and data.
drop table rules;
drop table data;
create table rules( id number not null primary key, rule varchar(255), true_action varchar(255), false_action varchar(255) );
create table data( id integer not null primary key, name varchar(255), age number, status varchar(255), description varchar(255) );
-- populate this tables with information.
insert into rules
select rownum id
, 'Age > '||least(a,b)||' and Age < '||greatest(a,b) rule
, 'Status = ''Valid'', description = ''Age in Range''' true_action
, 'Status = ''Invalid'', description = ''Age not in Range''' false_action
from (
select mod(abs(dbms_random.random),60)+10 a, mod(abs(dbms_random.random),60)+10 b
from all_objects
where rownum <= 2
insert into data
select rownum, object_name, mod(abs(dbms_random.random),60)+10 age, null, null
from all_objects

getQueryView().remove();
createViewObjectFromQueryStmt("QueryView", statement);
2. Page definition file contains an iterator (using iterator or methodIterator - doesn't matter) binding and table, which binds to the iterator, like:
<methodIterator id="distributeQuery1Iter" Binds="distributeQuery1.result"
DataControl="QueryServiceDataControl" RangeSize="10"/>
<table id="distributeQuery11" IterBinding="distributeQuery1Iter"/>
3. The page code uses <af:table>. But, if I use table binding (it's right) like this:
<af:table var="row" value="#{bindings.distributeQuery11.collectionModel}">
<af:forEach items="#{bindings.distributeQuery11.attributeDefs}" var="def">
the table will never changed (i.e. still show the first view instance).
When I tried to use iterator binding directly (it's bad and cannot provide all needed features unlike CollectionModel from table binding) I saw that table works!
(Code is somehing like:
<af:table var="row" value="#{bindings.myIterator.allRowsInRange}">
<af:forEach items="#{bindings.myIterator.attributeDefs}" var="def">
Why the table binding do not reflect changes in iterator? Or should I use different approach?
Thanks in advance!
Ilya.

I got it to work! I used a hybrid approach comprised of some of your code and some of Steve Muench's AcceessAppModuleInBackingBean example.
In the setBindings method, I execute an app module method that redefines the query, then I used your code to delete and recreate bindings and iterator:
public void setBindingContainer(DCBindingContainer bc) {
this.bindingContainer = bc;
rebuildVO();
The rebuildVO() method looks like the code you provided in your example:
private void rebuildVO() {
DCDataControl dc;
DispatchAppModule dApp;
DCBindingContainer bc;
DCIteratorBinding it;
OperationBinding operationBinding;
ViewObject vo;
DCControlBinding cb;
try {
bc = getBindingContainer();
dc = bc.findDataControl(DATACONTROL);
dApp = (DispatchAppModule)dc.getDataProvider();
// Execute App Module Method to rebuild VO based upon new SQL Statement.
dApp.setDispatchViewSQL();
vo = dApp.findViewObject(DYNAMIC_VIEW_NAME);
it = bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME);
it.bindRowSetIterator(vo, true);
// logger.info("Remove value binding...");
cb = bc.findCtrlBinding(DYNAMIC_VIEW_NAME);
cb.getDCIteratorBinding().removeValueBinding(cb);
bc.removeControlBinding(cb);
// logger.info("Creating new value binding...");
FacesCtrlRangeBinding dynamicRangeBinding =
new FacesCtrlRangeBinding(null,
bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME), null);
// logger.info("Add control binding...");
bc.addControlBinding(DYNAMIC_VIEW_NAME, dynamicRangeBinding);
} catch (Exception e) {
e.printStackTrace();
And my App Module method that redefines the view object looks like this:
public void setDispatchViewSQL() {
String SQL =
"begin ? := PK_BUsiNESS.F_GETDISPATCHVIEWSQL();end;";
CallableStatement st = null;
String ViewSQL = null;
try {
st = getDBTransaction().createCallableStatement(SQL,
DBTransaction.DEFAULT);
* Register the first bind parameter as our return value of type LONGVARCHAR
st.registerOutParameter(1, OracleTypes.LONGVARCHAR);
st.execute();
ViewSQL = ((OracleCallableStatement) st).getString(1);
findViewObject(DYNAMIC_VO_NAME).remove();
ViewObject vo = createViewObjectFromQueryStmt(DYNAMIC_VO_NAME, ViewSQL);
vo.executeQuery();
} catch (SQLException s) {
throw new JboException(s);
} finally {
try {
st.close();
} catch (SQLException s) {
s.printStackTrace();
When I run it I get my desired results. One thing I don't quite understand is why when the page is first rendered it shows the last set of records rather than the first. Now I have to figure out how to put navigation URLS in each of the table cells.
Thanks for your help; I would not have gotten this far without it,

Can you create a javascript dynamic menu based on security data in oracleDB

I am looking for a dynamic javascript menu that is generated based on the user role... basically i get the user role from ldap and then I have a Security table in oracle data base that has the permission info and i want to generate my dynamic menu based on the data in the database table.... the table has the following columns
private String userId;
private String security_level; // page level , field level
private String permission; //CRUD
private String permissionType; //ALLOW, DENY

Hello Suzie,
It is possible but you have "many" ways to do it, since what will happen is the javascript will be generated by an application.
Are you developing a J2EE application? with or without JSF?
The best way will be to Google to find a good Javascript menu library, and adapt the generation of it based on the content of your database.

Dynamic header based on the chosen Grid POV

Hello,
I have two grids Grid1 and Grid2. Both the grids have one editable POV and are different from each other. Either of the grids are being hidden based on a flag being input by the user.
I need to display the dimension name and the member name of the chosen Grid POV in a text box in the header. This needs to dynamically change based on the grid being displayed. e.g. If the Grid POV for Grid1 is "X" and for Grid2 is "Y", I need to display "X" when the grid2 is hidden and "Y" when grid1 is hidden. There is no conditional formatting on text boxes in headers. Is there any other way to do this?
Thanks,
Ravi B

Hi Ravi,
yes you can not apply conditional formatting on text boxes.
But it is possible to put the conditional formatting on the grid cell and then you can pick the text from grid cell into text box.
Hopefully this will solve your problem.

Rahul
