Interactive Report Performance With Conditional Link

Apex 3.2
I have a interactive report.
The underlying sql would return 127000 rows
The sql is
select
lde.ods_system,
lde.ldekey,
msg.sendersystem,
msg.messagetype,
msg.messageversion,
msg.msgseqnumber,
msg.alternatekey,
msg.crudmarker,
msg.clrbookdate,
msg.clrbookresult,
lower('udf_'||msg.messagetype) button,
lde.ldekey||'.'||msg.alternatekey||'.'||msg.msgseqnumber udm_key
from
clr_esbmessageheader msg,
clr_adm_systemmessage adm,
udm_lde lde
where
adm.ldeid = lde.ldeid and
msg.sendersystem = adm.system and
msg.messagetype = adm.messagetype and
msg.messageversion = adm.messageversion and
msg.receiversystem = 'SCIPS'
order by msg.clrbookdate desc
This report only takes 1 second to display.
I need to add a conditional link to another page, so I used
case
when lower('udf_'||msg.messagetype) = 'udf_distreceipt' then
'<a class="type" href="' || apex_util.prepare_url('f?p='||:APP_ID||':52:'||:APP_SESSION||'::'||:DEBUG||':RIR'||':IR_MSG_KEY,P52_PG:'|| lde.ldekey||'.'|| msg.alternatekey ||'.'|| msg.msgseqnumber ||','|| 50, null, 'SESSION') || '"title="Go to udf_distreceipt Report">udf_distreceipt</a>'
else 'no link' end table_link
The sql seems to be ok, because the report accepted it, but selecting the new column and saving the report takes forever (over 2 mins)
Now the report takes over 2 minutes to run and I still need to add more conditions.
Have I coded the link incorrectly ?
Gus

Hi Gus,
Are you wanting to put the link in the query for a specific reason?
I had to do a similar thing in the past and just completed the column link section for the column.
Why not just have the following in the query:
case
when lower('udf_'||msg.messagetype) = 'udf_distreceipt' then
udf_distreceipt
else null END table_link
Then do the linking using column link section:
You would specify your link text as #TABLE_LINK# which should then be conditionally displayed due to the case statement, then add in all the page item and values to pass across using a normal link column.
Thanks

Interactive report performance problem over database link - Oracle Gateway

Hello all;
This is regarding a thread Interactive report performance problem over database link that was posted by Samo.
The issue that I am facing is when I use Oracle function like (apex_item.check_box) the query slow down by 45 seconds.
query like this: (due to sensitivity issue, I can not disclose real table name)
SELECT apex_item.checkbox(1,b.col3)
, a.col1
, a.col2
FROM table_one a
, table_two b
WHERE a.col3 = 12345
AND a.col4 = 100
AND b.col5 = a.col5
table_one and table_two are remote tables (non-oracle) which are connected using Oracle Gateway.
Now if I run above queries without apex_item.checkbox function the query return or response is less than a second but if I have apex_item.checkbox then the query run more than 30 seconds. I have resolved the issues by creating a collection but it’s not a good practice.
I would like to get ideas from people how to resolve or speed-up the query?
Any idea how to use sub-factoring for the above scenario? Or others method (creating view or materialized view are not an option).
Thank you.
Shaun S.

Hi Shaun
Okay, I have a million questions (could you tell me if both tables are from the same remote source, it looks like they're possibly not?), but let's just try some things first.
By now you should understand the idea of what I termed 'sub-factoring' in a previous post. This is to do with using the WITH blah AS (SELECT... syntax. Now in most circumstances this 'materialises' the results of the inner select statement. This means that we 'get' the results then do something with them afterwards. It's a handy trick when dealing with remote sites as sometimes you want the remote database to do the work. The reason that I ask you to use the MATERIALIZE hint for testing is just to force this, in 99.99% of cases this can be removed later. Using the WITH statement is also handled differently to inline view like SELECT * FROM (SELECT... but the same result can be mimicked with a NO_MERGE hint.
Looking at your case I would be interested to see what the explain plan and results would be for something like the following two statements (sorry - you're going have to check them, it's late!)
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two),
sourceqry AS
(SELECT b.col3 x
       , a.col1 y
       , a.col2 z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5)
SELECT apex_item.checkbox(1,x), y , z
FROM sourceqry
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two)
SELECT apex_item.checkbox(1,x), y , z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5If the remote tables are at the same site, then you should have the same results. If they aren't you should get the same results but different to the original query.
We aren't being told the real cardinality of the inners select here so the explain plan is distorted (this is normal for queries on remote and especially non-oracle sites). This hinders tuning normally but I don't think this is your problem at all. How many distinct values do you normally get of the column aliased 'x' and how many rows are normally returned in total? Also how are you testing response times, in APEX, SQL Developer, Toad SQLplus etc?
Sorry for all the questions but it helps to answer the question, if I can.
Cheers

Interactive report performance problem over database link

Hi gurus,
I have an interactive report that retrieves values from two joined tables both placed on the same remote database. It takes 45 seconds to populate (refresh) a page after issuing a search. If I catch the actual select that is generated by apex ( the one with count(*) over ()...) and run it from sql environment, it takes 1 or 2 seconds. What on earth does consume the rest of the time and how to speed this up? I would like to awoid creating and maintaining local materialized views if possible.
Regards
Samo

Hi
APEX normally needs to return the full result set for the purposes of pagination (where you have it set to something along the lines of show x-y of z), changing this or the max row count can affect performance greatly.
The driving site hint would need to refer to the name of the view, but can be a bit temperamental with this kind of thing. The materialize hint only works for sub-factored queries (in a 'WITH blah AS(SELECT /*+ MATERIALIZE */ * FROM etc. etc.)). They tend to materialize anyway and its best not to use hints like that for production code unless there is absolutely no other option, but just sub factoring without hints can often have a profound effect on performance. For instance
WITH a AS
SELECT c1,
        c2,
        c3,
        c4,
        c5
FROM schema1.view1)
, b AS
SELECT c1,
        c2,
        c3
FROM schema1.view2)
SELECT *
FROM a, b
WHERE a.c5 = b.c3May produce a different plan or even just sub factoring one of the external tables may have an effect.
You need to try things out here and experiment and keep looking at the execution plans. You should also change Toads row fetch setting to be all 9's to get a real idea of performance.
Let me know how you get on.
Cheers
Ben

Interactive report column with an external link - Sort, chart functions

interesting.... the message text did not make it into the post (twice). But edit seems to work.
Our problem....
We have an interactive report with a column that in some cases will contain information allowing us to build a link. We have updated the report query to return the data tagged with the <a href..... on rows that can be links. The links are displayed and function correctly. However, if we click on the column header so we do something like sort, the page hangs. If we try to create a report using this column we get an error.
We have also tried marking the column as a link in the IR definition. With that design, the sort and reporting isn't an issue, but all the rows are links, which is not what we need.
Does anyone have any ideas on how to solve this problem?
Thanks, Nann
Edited by: Nann on Feb 6, 2010 11:07 AM

Hi Peter,
Thanks for your suggestion. We ended up with a slight variation in the design that allowed us to mark the column as a link.
Basically we have a column just for the link.
In our query we now have 2 columns. One that builds the url, the other the text we want displayed as a link.
If that row should not have a link in it the query returns null for both columns.
We only display the link column in the report.
We use the url column in the link definition .
We've disabled the sort and other functions on this column.
All works as we wanted.
Thanks
Nann

Interactive Reports - Performance Issue

Hi All
We have been getting ORA-04030: out of process memory … more and more frequently since first implementing Interactive Reports. From Enterprise Manager we had a look at the most costly queries and the one that stands out the most is:
SELECT *
FROM WWV_FLOW_WORKSHEET_CONDITIONS
WHERE CONDITION_TYPE = ‘HIGHLIGHT’
AND WORKSHEET_ID = :B2
AND SECURITY_GROUP_ID = :B1
ORDER BY HIGHLIGHT_SEQUENCE, NAME I have done all I can with the memory configuration and we are in the process of upgrading the servers to 64 bit Linux.
However, I noticed that WWV_FLOW_WORKSHEET_CONDITIONS table has 400,000 rows and the above query is performing a full table scan on it. As the query is run each time an IR report is viewed, this could account for the problems. The DBAs are of the opinion that the indexing and query are optimal and cannot be improved, so the obvious solution is to archive and purge the table.
Of the 400k rows, 80% are session values linked to sessions that no longer exists. It would appear that each time a user adds a filter or highlight to an interactive report it is recorded as a session value in the WWV_FLOW_WORKSHEET_CONDITIONS table. When the user logs out and closes the session, the values remain in the table and aren't cleared!!!? We currently average about 90 users a day with 60,000+ page requests so 400,000 rows is way more than I would expect to see.
Am I missing something? How do redundant session values get purged from the ir flows tables? Is there a (supported) way for me to clear them?
This is a critical issue for me now and I have raised an SR on metalink, but if the forum could offer some advice or assistance it would be very much appreciated.
Cheers
Simon
Bumped by: Shunt on May 12, 2009 11:00 AM

Hi Varad
Thanks for your help. I have had a good play with the purge function and now I'm more confused than ever. First let me explain my test scenario: I have an application with an interactive report in which I am logged in and able to make session changes (without saving the reports). I am observing the session activity on the Interactive Report using the apex_application_page_ir_rpt view which is set to filter on the application and page number for the Interactive Report I am testing.
Test 1
User logs into application, adds a filter to the report.
Result: A new row appears in the apex_application_page_ir_rpt view
Administrator Purges all sessions > 10secs old
Result: The new row is removed from apex_application_page_ir_rpt view
Test 2
User logs into application, adds a filter to the report.
Result: A new row appears in the apex_application_page_ir_rpt view
User logs out of application
Result: The new row remains in the apex_application_page_ir_rpt view
Administrator Purges all sessions > 10 secs old
Result: The new row still remains in the apex_application_page_ir_rpt view view
I hope that makes sense. Why would the session values not be cleared if the user logs out first? Why are they not then cleared if all the sessions are purged?
I am hoping that someone else can repeat the test and see if they find the same result.
Cheers
Simon

Interactive Report Performance

Hi everyone.. I don't see a setting for this, but I do see a need for this. I do have some interactive reports that have a decent amount of data, and this can cause page performance issues. I would love if there was a setting that allowed you to filter before fully rendering. This way I don't have to build a pre-report filter to help with speed.
Any other thoughts/suggestions?
Thanks,
Scott

do you want to filter rows?
I had a similar task and solved it like this:
- create a Interactive Report with few columns
- add a column with checkboxes
- write the selected boxes into a hidden text box
- use the string as filter option
=> the User can select single rows of interest
Also seen here:

Sry, it's german. But maybe it helps.

Interactive Report - aggregate with hide - bug or feature?

We are in the process of converting existing reports to Interactive Reports (IR), and adding a bunch of new ones. We ran into a roadblock when using IR with aggregates. To
reproduce, I created a test table with region, state, county, city and population columns. I created an interactive report, CONTROL BREAK on "Region", aggregate (SUM) on
population. The result looked like this.

Result #1:

Region: West
************
State County City Population
CA Orange County Irvine 100
CA Orange County Orange 200
CA Los Angeles Hollywood 300
CA Los Angeles Universal City 400
 Sum 1,000
When I clicked on City column, and chose to hide it, I expected the IR to resummarize the result to look like this:

Result #2:

Region: West
************
State County Population
CA Orange County 300
CA Los Angeles 700
 Sum 1,000
But what I saw was this:

Result #3:

Region: West
************
State County Population
CA Orange County 100
CA Orange County 200
CA Los Angeles 300
CA Los Angeles 400
 Sum 1,000
The data in the above result #3 is not presented the in way it should be for the users to comprehend.

In the non-interactive version, we display checkboxes for the users to show and hide the columns. If the column "City" is set by the user to "Hide", then we use the
condition on the column to hide the City column from the report, and use the query "SELECT ..., CASE WHEN :P10_SHOW_CITY = 'YES' THEN city ELSE NULL END As city, SUM
(population) FROM .. " to summarize the data. This displays results like the one shown in Result #2.

1. Shouldn't IR re-summarize the data to display results like I have shown in Result #2 when a column is hidden? We are able to achieve this with non-interactive version. Is this a
bug in IR?

2. Is there a way to get interactive report to display results like the way I have shown in Result #2?

3. Is there a way to retrieve the columns that are set to "HIDE" in IR so that we can modify our SQL to resummarize?

Script to reproduce:

Create table test_ir(
 region varchar2(50),
 state varchar2(50),
 county varchar2(50),
 City varchar2(50),
 population number(4))
insert into test_ir(region, state, county, city, population) values
('West', 'CA', 'Orange County', 'Irvine', 100)
insert into test_ir(region, state, county, city, population) values
('West', 'CA', 'Orange County', 'Orange', 200)
insert into test_ir(region, state, county, city, population) values
('West', 'CA', 'Los Angeles', 'Hollywood', 300)
insert into test_ir(region, state, county, city, population) values
('West', 'CA', 'Los Angeles', 'Universal City', 400)
select region, state, county, city, population from test_ir 
Thanks. 
 
Ravi

Hi Ravi,
When you add a control break, we do not re-generate the query to do group by. We just do control breaks. In the current version of APEX, to achieve what you are trying to see, you need to create an Interactive report with group by clause. If you want to use a dynamic query, the solution I suggest will not work.
The good news is in APEX 4.0, we are working to include group by view to an Interactive Report. This will let you select group by columns and aggregate functions to get the Result #2 you are trying to get.
If you wish to see how this works, we will be able to show if you come to APEXposed 2008, October 29 - 30, at Chicago O'Hare Wyndham.

Query Performance Is "Aggregates" the way out for me?
/people/vikash.agrawal/blog/2006/04/17/query-performance-150-is-aggregates-the-way-out-for-me
° the OLAP cache is architected to store query result sets and to give all users access to those result sets.
If a user executes a query, the result set for that querys request can be stored in the OLAP cache; if that same query (or a derivative) is then executed by another user, the subsequent query request can be filled by accessing the result set already stored in the OLAP cache.
In this way, a query request filled from the OLAP cache is significantly faster than queries that receive their result set from database access
° The indexes that are created in the fact table for each dimension allow you to easily find and select the data
see http://help.sap.com/saphelp_nw04/helpdata/en/80/1a6473e07211d2acb80000e829fbfe/content.htm
° when you load data into the InfoCube, each request has its own request ID, which is included in the fact table in the packet dimension.
This (besides giving the possibility to manage/delete single request) increases the volume of data, and reduces performance in reporting, as the system has to aggregate with the request ID every time you execute a query. Using compressing, you can eliminate these disadvantages, and bring data from different requests together into one single request (request ID 0).
This function is critical, as the compressed data can no longer be deleted from the InfoCube using its request IDs and, logically, you must be absolutely certain that the data loaded into the InfoCube is correct.
see http://help.sap.com/saphelp_nw04/helpdata/en/ca/aa6437e7a4080ee10000009b38f842/content.htm
° by using partitioning you can split up the whole dataset for an InfoCube into several, smaller, physically independent and redundancy-free units. Thanks to this separation, performance is increased when reporting, or also when deleting data from the InfoCube.
see http://help.sap.com/saphelp_nw04/helpdata/en/33/dc2038aa3bcd23e10000009b38f8cf/content.htm

Can Actions Menu of Interactive Reports work with Custom Authentication?

My testing is leading my to believe that Actions Menu do not work with Custom Authentication (but only work with APEX Authentication) in APEX 3.1.2? If that's true then is there a work around to this?
Just to clarify, I've posted/asked this question twice before:
1) Re: Actions Menu in Interactive Reports does not sort, filter, select cols etc
2) Interactive Report actions don't work for users (i.e. for non-developers)
But I've come to believe this is the main problem. I just don't know how to resolve/work around this?
Thanks for any help.

I haven't setup a sample because my custom authentication is using LDAP authentication. I'm not sure how I can replicate that on the samples server?
I'm using LDAP authentication with a Page Sentry function. My further testing reveals that the Page Sentry function is setting the APEX variable user to NULL (ie blank) whenever there's any code in the Page Sentry function box. PL/SQL code as simple as
BEGIN return TRUE; END;
in the Page Sentry function box sets the "user" is set to <null>. When the Page sentry function box is left empty (no code specified) it sets the "user" properly after authentication against the specified LDAP directory.
What all this has to do with Interactive Reports...
It seems like when the user is NULL it messes-up Interactive Reports that are stored in the flows database. Although it shows the default report properly, but no runtime interactive actions (filtering, sorting, column break, etc.) work.
Can someone please correct or confirm this?
Thanks.

Interactive Report filtering with hidden item column names

I have created an Interactive Report and changed some of the default column headings by using hidden Items with appropriate title. However, when I look at the filter option in the "Gear" drop-down, the only column names which appear are the default ones. There are blank lines for the columns using hidden Items. Any suggestions for having the hidden item content appear in the filter column name list?
Thanks,
George

George,
What is it you're actually trying to do here? Maybe there's an easier way?
Hidden items aren't going to show up in the Column List.
I'm guessing you're trying to separate a long list of column names using '----------' or something like that? We're looking to do just that in our application, but obviously we don't want to users selecting these dummy entries. We tried using the IR column groups, but those make the list look even more cluttered IMHO. (Plus setting the sort order w/in the groups doesn't seem to affect the drop-down column lists, which seems counter-intuitive to me).
If anyone has other suggestions for breaking up the column list display, I could use something immediately (going into beta-test in 2 weeks!).
Thanks,
Stew

Interactive Report, issue with backgroud color of Column Heading.

Hi,
I am using Theme -16
and there is a Interactive Report with the following columns Headings
Employee Name Employee No DOB
Now, the label of the first column is changed from Employee Name to Employee name.
The column heading is now displayed as follows.
Employee Employee No DOB
Name problem is when I add a break in any of the column heading..the background color of the column headings is different than the first one (little bit darker).
Why the background ground of the column heading is different in both these cases??.
Thanks,
Deepak

Why the background ground of the column heading is different in both these cases??.The report heading background is controlled by the CSS rule
.apexir_WORKSHEET_DATA th {
background: #4e4e4e;
font-weight: bold;
color: #fff;
border-top: 1px #ccc solid;
border-bottom: 1px #aaa solid;
white-space: nowrap;
vertical-align: center;
letter-spacing: 1;
font-size: 8pt;
background-image: url(../ws/report_bg.gif);
background-repeat: repeat-x;
}This uses a [gradient image|http://apex.oracle.com/i/ws/report_bg.gif] that is repeated horizontally to provide a shaded background from light to dark grey. As the background image doesn't repeat vertically, when the height of the heading is more than the height of the image the gradient is replaced by the underlying background colour (#4e4e4e). This is what's happening when the break is inserted into the header text: the height of the heading increases, causing more of the darker area of the background image/underlying colour to be visible.

Hyperion Interactive reporting performance issue.

Hi,
We created a report in Hyperion Interactive reporting using Hyperion Essbase as database connection file .
Report performance was good in Interactive reporting Studio we don't have any problem in studio.
when we open the the report in Hyperion Workspace We are facing performance issue of the report and also when i hit refresh button to refresh data in the Workspace,i am getting the following error message
*"An Interactive Reporting Service error has occurred - Failed to acquire requested service. Error Code : 2001"*
Any suggestions to resolve this will be really helpful.

Hi
i also faced such an issue and then i found the answer on metalink
Error: "An Interactive Reporting Service Error has Occurred. Failed to Acquire Requested Service. Error Code: 2001" when Processing a bqy Report in Workspace. [ID 1117395.1]
Applies to:
Hyperion BI+ - Version: 11.1.1.2.00 and later [Release: 11.1 and later ]
Information in this document applies to any platform.
Symptoms
Obtaining the following error when trying to process a BQY that uses an Essbase data source in Workspace:
"An Interactive Reporting Service error has occurred. Failed to acquire requested service. Error Code: 2001".
Cause
The name of the data source in the CMC contained the machine name in fully qualified name format whereas the OCE contained the machine name only. This mismatch in machine names caused the problem. Making the machine name identical in both cases resolved the problem.
Solution
Ensure that the name of the data source as specified in the OCE in Interactive Reporting Studio matches the name specified in the CMC tool in the field "Enter the name of the data source".
In fact, all fields need to match between the OCE and the CMC Data Source.

Interactive Report - problem with export by email

Hi,
We're upgrading to Apex 4.0 and we encountered a problem with the email export in html format for the Interactive Reports. The french accents are displayed with some weird symbols in the HTML file.
When I export directly in html from my report instead of the email, the accents are fine. So the problem must be the encoding of the email which is set to UTF-8. Our database use WE8MSWIN1252 encoding for the NLS Characterset.
Without changing our NLS Characterset, is there something I can do to correct this ?
Thanks
