I am working/maintaining an application built on Oracle ADF 11.1.1.4 version migrated from 10g during developement phase itself. We are using BC4j to talk to Oracle 10g database. The application is very heavily data centric and so there are chances that the query triggered through GUI may be have bad plan based on the search criteria entered by the user. Most of the places we have marked few fields mandatory to search on where potentially we see a bad query to be formed.
Issue: Currently in production user open muliple tabs for different screens, one of which is a screen where we have made it mandatory to enter few search values before searching/Querying the data. In the corresponding view criteria of that View Object we have marked those fields as selective required. But somehow we see a blind query triggered even when user hasn't clicked on search button on that page
It seems to comeup when the session expires on one of the pages opened and user clicks the OK. button
I am not sure is the framework triggereing some blind query when the page expires or else. There are many listeners on the page, but I am not sure why session timeeout can cause it.THe query is the same as that in the corresponding VO where we have maked few fields as selectively required. The long running query causes stuck thread on Weblogic server causing it to crash eventually after sometime.
Kindly anybody please advise if there has been an Oracle bug reported or any solution. We are seeing this on couple of pages where view criteria has few fields marked as selectively required.
Thanks

You might be running into an effect as described here http://andrejusb.blogspot.ca/2012/08/adf-bc-passivationactivation-and-sql.html?m=1
You can try the technique I showed here https://tompeez.wordpress.com/2012/03/18/jdeveloper-preventing-return-of-large-row-sets-on-page-load-of-vo-using-bind-variable/ to prevent executing of queues on first load.

Please, I created this report and published it on the web
But it is interesting that the filters that I enabled in three columns do not appear - they only work on my computer, in the desktop version. Does Publishing to the Power BI Web not allow you to include filters?
Filters should work the same with Publish to Web.
One thing you need to keep in mind is that there can be a significant lag between publishing the file and when the public link is updated.
From Microsoft documentation:
How it works (technical details)
When you create an embed code using Publish to web, the report is made visible to Internet users. It's publicly available, so you can expect viewers to easily share the report through social media in the future. Users view the report either by opening the direct public URL or viewing it embedded in a web page or blog. As they do, Power BI caches the report definition and the results of the queries required to view the report. This caching ensures that thousands of concurrent users can view the report without impacting performance.
The data is cached for one hour from the time it is retrieved. If you update the report definition (for example, if you change its View mode) or refresh the report data, it can take some time before changes are reflected in the version of the report that your users view. When a data refresh occurs for an import data model, the service clears the cached data and retrieves new data. In most cases, the data is updated nearly simultaneous with the import of the data. However, for reports with many distinct queries, it may take some time to update. Since each element and data value is cached independently, when a data update occurs, a user may see a mix of current and previous values. Therefore, we recommend staging your work ahead of time, and creating the Publish to web embed code only when you're satisfied with the settings. If your data will refresh, minimize the number of refreshes and perform the refreshes at off hours. We don’t recommend using Publish to web for data that needs to refresh frequently.
Make sure you have the Filtering enabled in the 'Options and settings' section of the Desktop PBI before publishing.

I have implemented a website using Oracle Webcenter Portal (WCP) integrated with Oracle Webcenter Content (WCC).
Some pages of the website need to show public documents that are stored in WCC. In order to do this I use WCP content presenters. However, I realized that, in order for the document to be visible to a user that is not logged in, that document must have no account associated in WCC.
However, for security reasons, prior to it's release the document needs to have an account.
I was trying to use WCC Workflow events to alter the account using wfUpdateMetaData Idoc function. However, after some research I realized that this function is only capable of altering metadata that was manually created by me.
Is there any way to achieve this?
Thanks in advance.
You have two possible approaches:
It is possible to give access to non-logged in users, by giving access rights to Guest. It's probably not what you want, so I'll leave this option without further description for now.
Second option is to change account by using executeService to call the UPDATE_DOCMETA service. It might an issue that the document is in an active workflow and you might have to call wfRelease prior to the service call (I have no possibility to test it right now)
I have around 20 OBIEE Reports and these Reports automatically refreshed after a certain time period (different for each report). Users navigate to these reports through my SharePoint site home page. Now, I want to display which report is refresh at time in SharePoint page.
Is there any way I can achieve this capability?
Please let me know if requirement is not clear.
Not sure if you comprehend how OBI and analytical systems work but let me make something clear:
It is NOT the "OBIEE Report" getting refreshed.
First of all because OBI uses "Analyses" whereas BIP uses "Reports".
Second and most importantly it is because the DATA SOURCES are refreshed. The "analysis" is just a visualization container and nothing else. OBIEE does not store or persist data.
Will a single GSA search request that specifies two site collections get loaded into the suggestions database for both sites?
For example consider the following query,
http://gsa/search?q=hello&site=site1|site2&client=myfrontend
If results are returned from both collections will the query "hello" get loaded into the suggestion database for both,
1. client=myfrontend&site=site1
2. client=myfrontend&site=site2
So far I have not seen the query get loaded into either suggest database, but perhaps I have not waited long enough, which makes me wonder is there any way to quickly reset/reload suggestions? In the past I have tried resetting them via admin console's suggestions page, and then enabling/disabling suggestions via the frontend, but it does not always regenerate them. Is there any other procedure people follow to reload suggestions?
Contacted Google support and, if multiple collections are defined in search request the suggestion gets logged to the default_collection.
They are working on a resolution :)
I've spent 2 whole weeks in googling some working sample on this. I was almost kind of knocking my head against concrete wall....deeply suffering until now.
Ok, I have a simple web page to display two columns, say, Msg & MsgID, from a table named MsgLog in MS SQL Server. I have stored procedure that will insert new Msg entries into the table. (in future, possibly could update existing entries)
My desire is, whenever there is a new msg entry inserted, or an existing msg entry got updated, the web page must automatically reflect this change without user clicking any page button, or without any coded timer function, otherwise the web page just leave as it is. The page refresh can only be triggered by database table change.
I read lots of internet posts regarding using SqlCacheDependency to achieve this, but none provides complete steps and codes. I tried to tweak their sample codes in my project, but none of work successfully, as I predicted. Or is it impossible to implement this?
My development environment is: Visual Studio 2010 professional, using ASP.NET FRAMEWORK 4.0, MVC 3 application using C# with embedded sql statements with SqlCommand object, database is MS SQL Server 2008 enterprise editon, IIS express.
Can someone genius to show me complete workable detailed steps from sql server setting, to coding. Functionality is just as simple as display rows with 2 columns from one table in a web page, and reflect changes realtime if and only if the table got updated or inserted. Not using polling or timer techniques; Not using LINQ to SQL, but using SqlCommand.
thanks millions of thousannds.
This in itself doesn't have to do directly with SqlCacheDependency.
You are wanting to do something that until only recently was really done with timers/polling unless you were one of the big players (ie google chat) Once your server notification event is raised then use SignalR to notify the clients of the change, so it requires an 'open' connection. Otherwise polling/refreshing is your only option. I haven't used SignalR, but I do know its really your only option now to do what you want. There have been some other projects in this field, but this is your best bet by far.
