Application Express :: Clear Page Cache - All Except Specific Items?
Feb 21, 2013
APEX 4.2.1 On a page with dozens of editable page items, when branching back to the same page on-submit, is there a way to clear cache for all items except a few (key) items? The branch attributes (via the f?p= syntax) support clearing cache for the entire page and setting specific item/value pairs but no support for exclusions.
i have created form with table page to enter hotel details there is on 6 check box which are not database column .i have create these check box to keep days details when hotel give service .so i have use
these 6 check box are used Source used :Only when curren value in session state is nullSource Type : Static Assignment (Value equals source attibute) Problem are when i create new record then these 6 check box are not clear cache and when i update any record value are not clear cache . i need when i create or update recor then all 6 check box should be null after keep recor.
When I create a new page item via copying from existing page item it fails with the below error code, if there is > or < character in the source of the existing item.Error Source contains <, > or " which are invalid characters. It works fine if I create new item using wizard and then have the same source. I use div tags in the source of my display only items.
I have a master-detail form which was getting close to the 100 items per page limit in Apex 4.0 which I then scaled back and got to work properly. I had thought that I could start adding more columns to the detail part of the form since 4.2 was supposed to have increased that limit. I am finding that this does not seem to be true at least in the case of this particular form. I tried increasing and started getting 404 errors when trying to save data--same symptom I had had with 4.0. I am back nearly to the same # of columns I started with--and nowhere near the 200 limit. Columns are month by month projection data that I had hoped to extend with the increased page item limit.
I missing something required to take advantage of larger page items limit? Do I need to use one of the new templates?
db11gxe , apex 4.0 , firefox 24 , I have a page with a report and two items , and i want to print the whole page (the report with the items) , can apex do so ?
Im tring to dynamically hide/show page item. I searched and found something but it not working for me. Im using apex 4.1 and below described are work I did.
In my page (form) I have 5 fileds iitems.
- Customer No - Edit - First Name - Last Name - Address
I want to hide First Name, Last Name, Address based on the value in Edit. Let say if user selects "Edit First Name" then First Name must get visible while Last Name & Address hidden.
So I placed this line onChange="$f_Hide_On_Value_Item(this,'LASTNAME,'LN')" in page item EDIT> Label > HTML Table Cell Attributes
I have "After header" process (with PL/SQL code) in "Page Rendering" section and want to navigate to some page after this process has been completed. I created a branch (On Submit: After Processing) with Target Type: URL. But this branch is executed only after "Page Processing", not after "Page Rendering". Maybe , there is any APEX API functions for pages navigating..
I have created tabular form. I have set LOV for one column. Here my requirement is when i select the value from lov then it will fetch that value into page item.
I have 20 item fields in same form. i need to align them in sequential manner. For example x y z abcl m o p q r s xyzabclmopqrs are the items to achieve this what i have to do...
I am facing this problem, not sure how to solve this. Basically, the default value of the "items" on the page don't get set when the session is cleared and I visit the page for the first time.
So when I check the session for the first time, all page items are null. But when I revisit the page, the page items gets set sometimes.
To branch & scroll to a specific position within a page (upon initial page load), is using a named anchor still the recommended/modern way to do this or is there some jQuery plugin goodness that does a better job?
i have IR report page and download column as blob,how can security applied in specific column wise?e.g. Report page have more rows, and applied query in condition.
Select ID,dbms_lob.getlength(Blob_file) Download from Document_master where Created_by=UPPER(:APP_USER) OR (exists (select '' from apex_workspace_group_users awgu where awgu.user_name =:app_user AND awgu.GROUP_NAME='EMPLOYEE_GROUP' ) )
Now all the rows with Download column to see EMPLOYEE_GROUP users,but i need control the download column only except Created_by=UPPER(:APP_USER) ,this case how can do the security.
I created a master-detail form using wizard in oracle apex 4.2 Now I want to attach an LOV to one of the items of detail form, which is visible on the same window as of master form. To do so, I need to first find the item in detail page, details of which are not available in page definitions. I can see all the items of master form but none for detail form in "Page Rendering" section.
i am testing a proc after tuning it but the problem is, it is taking a very very less time which it shouldn't. I know that it is because of the buffer cache and the shared pool. that why i need to clean the cache to retest it.
I cannot bounce the database as other schemas are part of it. so is there any way to clean the cache for that particular schema i.e bouncing any particular schema(i know that the term is not appropriate).
Recently i created a form which contains emp_name,deptno,supervisor_name.For emp_name if i type the emp name (eg:allen) it will show me a list of employees named allen as a select list.For that i used a jquery script on page header
and i have created a dynamic action for emp name to fetch the deptno,supervisor_name if select the employee name it is working fine is if i type a emp_name which doesn't exist in the employee table it will show me a alert message employee does not exist and it will clears all the fields.
We are using Application Express 4.1.0.00.32 on Wondows XP and Oracle version is 10g. I've created a report in APEX and the user is insisting on putting a header on each page in PRINT of the report which should contain the "from date" and "to date", which are present on the select criteria on top.
Can I somehow add from_date and to_date items in Title so that when they print the report, they'll see the from and to dates in the title?Or is there someother way to do this. The report is an interactive report with a control break and user prints the report with file->print.
I am new to APEX and I am developing an application to manage Oracle database user accounts. I have a page (8) that has text items for the username and the database name. I have a submit button (this works fine) that will issue the ALTER USER... statement to reset the user's password and unlock the account. I have another button that should:
get the value of the username - P8_USERNAMEassign it to an application item - FIND_USER_IN_DBredirect to page in application - to page 11
The issue is that FIND_USER_IN_DB does not get populated and page 11
which is a simple report with the following query:
I've been creating numerous sample applications. In my latest one, I've been working on custom security schema and it's been working great for the most part. The one issue I'm having is passing login values into my application items. Though I don't receive any error messages or anything, upon checking the value of the application items via the session button, they never contain anything. The code I have in place on my login page is as follows:
begin select username, user_id into :F56_USER_NAME, :F56_USER_ID from GS_USERS where username = lower( rtrim( ltrim( :P101_USERNAME ) ) ); [code].........
I have different public page (page1) and different page for authorized user(page5).Upon successful login after process validation ,computation it should navigate to authorized user page 5 but the branching does work it keeps on going to page 1 .
I have an application built in Apex 4.2It's been running fine for several weeksI've not made any changes to the codeSuddenly it developed what seems to be a cache problem.If I enter a search criteria; it displays results. I enter a different search criteria and it brings back the same results as the first criteria.I enter a search criteria in a different field and I still get the results from the first searchI go from Internet Explorer to Mozilla.
DIfferent search criteria, but same issue. Google chrome - same issueThe obvious answer is to clear the cache.I have a process set up that is clear Cache for Items , on submit after computations and validations and then I list all the items individually.This process has been there all along.
I never had this problem before.If I log out and come back in, same issue. What ever I enter as the first search criteria is the results no matter how I search
I have 2 regions in my application one is html form region and another is tabular form .I created 6 items in html region and created DA for the items to hide according to the value of items and then created tabular form

once i select the first item(declaration letter) it will show the second item (applicacable) perfectly,but when i select applicable as yes and discrepancy then all the items become misplaced,
I am using theme 4, topaz. Region_Position_06 is a home link.
I have placed a company graphic at this position on page zero, and when a user clicks it on any page, she exits that page and goes to the home page, a main menu page. So no matter how deep a user may be into the application's pages, she may always click this logo image and return directly to the main menu page.
This is convenient, but there is one problem. Clicking this logo does not clear the cache on the page the user is exiting or, for that matter, on any page in the trail of pages the user took to get to the current page. I navigate primarily with buttons and always clear the cache on a page when I exit it. I need to find a way to do this when a user clicks the logo image.
The values are stored in a VARCHAR2 field MULTI_USER (for example 1:2:4:6) When I want to get the names back from the selected item, how do I reference the colon-separated items?
For example:
Select Name from UserTable where UserID in (select MULTI_USER from MULTI_USER where MULTI_USER_ID = 1)
We had several unexplained lock-ups of APEX in our environment in the last months. This all happened after we moved to GlassFish with the APEX Listener. The symptoms were always that all connections in the JDBC connection pool were in use and we had to restart the GlassFish server instance to free them up.
The culprit is the caching folder that the APEX Listener uses for file caching. We use this to cache image downloads from the database through a procedure, and the caching folder was set to /tmp/apex/cache. I believe this is the default setting. All went well, when the procedure was called the images were downloaded from the database and cached under /tmp/apex/cache. However, for some (as yet unexplained) reason, Linux sometimes removes this folder from the /tmp file system. This seems to happen from time to time after an unknown period of inactivity. We didn't reboot the server. After the folder is gone, the APEX Listener is unable to recreate it, keeps on creating new database connections until the maximum configured is reached, and we need to restart the GlassFish instance to free them up. This also recreates the caching folder.
Our environment: GlassFish 3.1.1+3.1.2, APEX Listener 1.1.3, Oracle Linux 6.2. I didn't try out the new APEX Listener 1.1.4 yet so I'm not sure if this has been fixed in the last version.(kind of reminds me of the problem where the APEX config file is by default placed under /tmp and also disappears from time to time)
