Delay time for Cancel query dialog

Hi Folks.
I have a form where the property Interaction Mode is set to NONBLOCKING.
When a slow query is initiated, the cancel query dialog is displayed after approx. 5 secs.
Can anyone tell me if it's possible to alter the delay time before this dialog is shown e.g., to 30 secs?
Regards

Cancel Query dialog does not show for long queries

Hi,
I've set the interaction mode of my form to non-blocking. I then ran a long query which takes about 5 minutes to display the results. The Cancel Query popup that everyone is talking about is still not showing.
What should my settings be to make the Cancel Query dialog popup? My client wants to have the option to cancel a query while it is still processing.
I'm using Oracle Forms 9.0.4.0.10 and Oracle Database 10g.
Any help with regards to this will be highly appreciated.

Set frame delay time for animated gif using ImageIO

I'm trying to change the delay time of each frame for an animated gif by changing the metadata for each frame as following but it doesn't change anything.
static private IIOMetadata setMetadata(IIOMetadata metadata, int delayMS) throws IOException
          Node root = metadata.getAsTree("javax_imageio_gif_image_1.0");
          for (Node c = root.getFirstChild(); c != null; c = c.getNextSibling())
               String name = c.getNodeName();
               if (c instanceof IIOMetadataNode)
                    IIOMetadataNode metaNode = (IIOMetadataNode) c;
                    if ("GraphicControlExtension".equals(name))
                         metaNode.setAttribute("delayTime", Integer.toString(delayMS));
     }Does anyone know how to set delay time for animated gif using ImageIO ?

Significant difference in response times for same query running on Windows client vs database server

I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
Ideally I would like to get a response time equivalent on the Windows client to what I get when running this on the database server.
In both cases the query plans are the same.
The query and plan is shown below :
{code}
SQL> explain plan
2 set statement_id = 'SLOW'
3 for
4 SELECT DISTINCT /*+ FIRST_ROWS(503) */ objecttype.id_object
5 FROM documents objecttype WHERE objecttype.id_type_definition = 'duotA9'
6 ;
Explained.
SQL> select * from table(dbms_xplan.display('PLAN_TABLE','SLOW','TYPICAL'));
PLAN_TABLE_OUTPUT
| Id | Operation          | Name      | Rows | Bytes |TempSpc| Cost (%CPU)|
|   0 | SELECT STATEMENT   |           | 2852K|    46M|       | 69851   (1)|
|   1 | HASH UNIQUE       |           | 2852K|    46M|   153M| 69851   (1)|
|* 2 |   TABLE ACCESS FULL| DOCUMENTS | 2852K|    46M|       | 54063   (1)|
{code}
Are there are configuration changes that can be done on the Oracle client or database to improve the response times for the query when it is running from the client?
The version on the database server is 10.2.0.1.0
The version of the oracle client is also 10.2.0.1.0
I am happy to provide any further information if required.
Thank you in advance.

When I run the same query on a Windows client it completes in 47 minutes.
There are NO queries that 'run' on a client. Queries ALWAYS run within the database server.
A client can choose when to FETCH query results. In sql developer (or toad) I can choose to get 10 rows at a time. Until I choose to get the next set of 10 rows NO rows will be returned from the server to the client; That query might NEVER complete.
You may get the same results depending on the client you are using. Post your question in a forum for whatever client you are using.

Run time for a query

Hello all,
Can you please tell me how can I see the total running time for a query?
What other transactions besides ST03 and RSRT with statistics on?
Points will be assigned
Thanks
Ramona

Hi........
You can use ST03N -> BW System Load
Depending on the time frame you select, you get historical data or
current data.
To get to a specific query you need to drill down using the InfoCube
name
Use Aggregation Query to get more runtime information about a
single query. Use tab All data to get to the details.
(DB, OLAP, and Frontend time, plus Select/ Transferred records,
plus number of cells and formats)
Also You can get it in RSRT,RSRTQ...

Query Execution Time for a Query causing ORA-1555

dear Gurus
I have ORA-01555 error , earlier I used the Query Duration mentioned in Alert Log and increased the Undo Retention as I did not find th UnDOBLKS column of v$undostat high for the time of occurence of ORA-01555..
But new ORA-01555 is coming whose query duration exceeds Undo Retention time..
My question -
1. Is it possible to accurately find the query duration time besides the Alert Log file ?

abhishek, as you are using an undo tablespace and have already increased the time that undo data is retained via undo_retention then you might want to consider the following ideas which were useful with 1555 error under manual rbs segment management.
1- Tune the query. The faster a query runs the less likely a 1555 will occur.
2- Look at the processing. If a process was reading and updating the same table while committing frequenctly then the process under manual rbs management would basically create its own 1555 error rather than just being the victum of another process changing data and the rbs data being overlaid while the long running query was still running. With undo management the process could be generating more data than can be held for the undo_retention period but because it is committed Oracle has been told it doesn't really have to keep the data for use rolling back a current transaction so it gets discarded to make room for new changes.
If you find item 2 is true then separating the select from the update will likely eliminate the 1555. You do this by building a driving table that has the keys of the rows to be updated or deleted. Then you use the driver to control accessing the target table.
3- If the cause of the 1555 is or may be delayed block cleanout then select * from the target prior to running the long running query.
Realistically you might need to increase the size of the undo tablespace to hold all the change data and the value of the undo_retention parameter to be longer than the job run time. Which brings up back to option 1. Tune every query in the process so that the job run time is reduced to optimal.
HTH -- Mark D Powell --
dear mark
Thanks for the excellent advise..I found that the error is coming because of frequent commits..which is item 2 as u righly mentioned ..
I think I need to keep a watch on the queries running , I was just trying to find the execution time for the queries..If there is any way to find the query duration without running a trace ..

Cannot change delay time for animated GIFs

I just got PSE 6.0 for Mac, and I've slowly been learning how to do what I'd like to with it. I've noticed that there have been some problems with the program, though, such as sudden lockups that make me force-quit. One of my more serious issues involves making adjustments to the delay time in some simple, animated GIF files that I have been working on, using the Save For Web command. For some reason, I can't change the delay time from its default of 0.2 seconds to anything else; the slider doesn't respond when I click on it, nor can I make any direct adjustments in the field itself. In the end, I'm stuck with just that 0.2-second delay. Is this a bug in the program, or am I just missing something?
If this helps, I have created a set of animated GIFs with two layers/frames apiece, looping continuously. The second and topmost layer is asigned a Dissolve filter, and usually left at 100% opacity when I make the final adjustments. The workspace background for each is transparent when I begin.
Oh, also, I am using PSE on an Intel iMac with OS 10.5.6, with 2GB RAM and enough hard drive space to fit everything.

Unfortunately, this is a known bug in PSE 6 for mac:

How to change the view criteria at run time for af:query

Hi,
I've a usecase where I need to change the view criteria of the af:query at run time.
Use case:
=======
1) Consider a check box (Show Emps Under Dept 10) in the query panel when user selects and clicks 'Search' button should show the employees under dept 10. If user searches without selecting the check box, the results should show all the employees in all the departments.
2) I need to have a check box always in the query panel. Its mandatory.
The way I implemented:
==============
1) Created a transient variable 'Show Emps Under Dept 10' in the EmployeeVO and also created a bind variable bind_DeptNo.
2) Create a view criteria 'AllEmployees' which has only the transient attribute as the view criteria item and whose value set to 'false' by default.
3) Created another view criteria 'EmpUnderDept' which has 'DepartmentId' as the view criteria item and whose value set to the bind variable 'bind_DeptNo'.
4) Dropped the view criteria 'EmpUnderDept' as the 'af:query' panel in the jspx page.
5) Overridden the queryListener as '#{EmpBean.empSearch}'
6) Has the below code in the empSearch method as below. When user selects the check box, applying the other criteria 'EmpUnderDept' and setting the bind variable to '10'.
public void empSearch(QueryEvent queryEvent) {
// Add event code here...
QueryDescriptor queryDesc = (QueryDescriptor) queryEvent.getDescriptor();
ConjunctionCriterion conCrit = queryDesc.getConjunctionCriterion();
List<Criterion> criterionList = conCrit.getCriterionList();
List criterionValues = new ArrayList();
Object criteriaValue = null;
int criteriaNo = 0;
DCBindingContainer bc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
FacesContext facesContext = FacesContext.getCurrentInstance();
for (Criterion criterion : criterionList) {
AttributeDescriptor attrDescriptor = ((AttributeCriterion)criterion).getAttribute();
System.out.println("============== attrDescriptor.getName() =================== " + attrDescriptor.getName());
criteriaValue = ((AttributeCriterion)criterion).getValues().get(0);
if(criteriaNo==0) {
Boolean val = (Boolean) ((AttributeCriterion)criterion).getValues().get(0);
if (val.equals(true)) {
OperationBinding method = (OperationBinding) ADFUtil.findOperation("ExecuteWithParams");
if(method!=null) {
Map params = method.getParamsMap();
//params.put(key, value)
method.getParamsMap().put("bind_DeptId", 10L);
method.execute();
ADFUtil.invokeMethodExpression( "#{bindings.EmpUnderDeptCriteiaQuery.processQuery}", queryEvent);
} else {
//ADFUtil.invokeEL("#{bindings.ExecuteWithParams.execute}");
ADFUtil.invokeMethodExpression( "#{bindings.AllEmployeesCriteriaQuery.processQuery}", queryEvent);
But this approach is not working and its always showing all the employees in all the departments.
Please let me know if there is a way to change the view criteria at run time depending on the values set at run time for one of the view criteria items.
JDev version am using is '11.1.1.5'
Thanks,
Lakshman

Hi Shay,
It worked for me without overriding the executeQuery() method in the ViewImpl.java.
Instead of creating 2 view criteria, I created only one which has both transient variable and the DepartmentId = <bind_DeptId>. With the above code, it worked properly. Now I am using only one view criteria.
Thank you.

Because the cost is internally calculated by the Cost Based Optimizer using the data available when parsing the query (tables, columns, constraints, cardinalities, etc...). If you feed it bad information (stale statistics, not using NOT NULL constraints, check constraints, foreign key constraints, etc..) it chooses inappropriate access methods.

Remaining time for a query

Hi,
I wonder how much remains for a long sql query to be completed since the oracle views?
I kown that OEM give this information, but unfortunatly i don't have this tool :-(
Any idea..
Thanks in advance.

If, for example, you have an update statement that requires a full scan of a large table, the full scan may appear in v$session_longops along with total work and time remaining etc. But that would be a fairly simple example. Index lookups such as range scan don't appear in this view, along with a number of other operations such as nested loops, so if your execution plan contains these operations, you're not going to get much from v$session_longops. Even if you do have operations that all appear in v$session_longops you would need to cross reference it with the execution plan to determine which operatios have completed but until the operation begins, you won't be able to get an estimate of the run time.
Also remember that OEM is just querying the same views so it can't give you anything more than what's available in the v$session_longops and the supporting plan tables etc.

Is it possible to limit the execution time for a query?

I have an application that will run a query to gather statistics. The time window is defined by the user. Since the polling period for data collection varies, it is not possible to say that a large time window will result in a large resultSet. I may have a polling period of 1 minute or a polling period of 1 hour.
I want to avoid a user executing a query that will consume too many resources and inpact the system's performce in general. Could I stop a query after it takes more that x secs? Is there a way to write an sql statement indicating the max response time? similar to rownum?

You can also create an Oracle profile with limited resources and assign it to the Oracle account running the queries (this profile will be used for all queries run by the corresponding user). Resources can only specifed in cpu time (not elapsed time) or logical reads.
See http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96521/users.htm#15451
and http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_611a.htm#2065932

Estimated time for a query execution -- URGENT PLEASE

Hi,
I am interested in knowing the time of execution of a query before actually running it. Is there any stored procedures/methods that gives us this feature.
Thanks.

Without actually running the query, there's no way to find out how long it will take to run. I'm not even sure that there's a theoretical way to do this.
You can use the v$long_ops table to see roughly how far along a long-running query is while it's running.

Response time for Error Messages - Please Help

Hi
I have a PRO C application talking to an Oracle database.
The Response time for successful query is within desirable limits.
But when there is a error condition (eg SQLError -3113,or connection refused) it takes more than 9 minutes for the database to respond with the error code.
This condition is observed with only one database while the others are working fine.
What is the reason for this? Can’t it be reduced?
Regards
David

ever been faced with the same problem ?
Why deleting ? It that only one way to fix this problem ?
What are the others doing in such cases. Or am I the only one person
where has this special problem on the world. Becides I dont believe
in solving the problem through removing mentioned directory and
reinstalling. Nevertheless I will try it. I let you know about the result.
