What is clearing cache for?

I have an iPad 2. What is the purpose of clearing the cache? What's it for?

I presume you are referring to clearing the cache in Safari. Web browsers keep a copy of web pages you visit to make it faster to reload them should you revisit the page. Clearing the cache removes these temporary copies.
For a more detailed explanation, see:

Clear Cache for Items

Hello again,
i`ve made simple process with type "Clear Cache for Items (ITEM,ITEM,ITEM)" and with process point "On Load - Before Header" through wizard, in "Process" field i`ve inserted all items what i want to be clear on page load(from list below). When i run my page, error is:
Error ERR-1002 Unable to find item ID for item "P12_BIT " in application "123".
OK
Unexpected error, unable to find item name at application or page level.
but, item P12_BIT exists!! and it`s type is "radiogroup", such error is on all items that is in process.
in another app this process works good.. Maybe error is because app 123 i`ve imported?? How can i solve it??
Thanks for help anyway!!

Jelena,
In the message:
Error ERR-1002 Unable to find item ID for item "P12_BIT " in application "123".
I see some whitespace after the item name. Looks like we're not preparing that string as well as we should. Please try removing whitespace from the comma-delimited list of item names in the process definition and let us know if that doesn't work.
Thanks for pointing this out.

How to clear cache for a tab through api

How do i clear cache for a tab programatically?

All this info applies to
Portal version 9.0.2.6.18
I found that there is portlet called "clear cache",
under provider portal tools. This when placed on a tab can clear the cache of that tab for a user.
I found this as a work around for the API.

Clear cache for items not working with multiple items

APEX 4.0, 11g. I've made a session state process that clears cache for items (item_1, item_2, item_3) but I keep getting an error "Unexpected error, unable to find item name at application or page level" I have now created 3 session state processes, each with one page item in it, and it works fine but as soon as I try to put more than one item in the process field, separated by commas, I get this error. Is there some other setting I have to change to make it accept multiple values in this field?

No, I wasn't using the parenthesis... just the items separated by a comma.
I don't want to clear the cache for all page items, just these 3. It works okay in 3 separate clear cache for item processes, just thought it was odd that I can't put all three items into one process separated by commas.

Clear Cache for Certain Items on Tab Click

I found this in the forms:
If you want to clear the cache of the page submitted when the tab is clicked, that should be the job of that page. You can create an after-submit process (before computations and validations) with:
apex_application.clear_page_cache(:APP_PAGE_ID);
However, I need to clear certain items not everything on the page. I tried substituting apex_application.clear_item_cache(:APP_ITEM); but that doesn't work. What is the process that clears the apex_application item cache?

Is the page you're clicking away from executing a submit when you click away? If so, I would try either of these in a page branch.
Assume you are on page 1 and clicking to page 2. On Page 2, let's say you want to keep the cache on items P2_A, P2_B but clear the cache for P2_C.
In your page branch (defined on page 1) that fires to take you to page 2, try either of these:
Clear cache on page: 2
Set these items: P2_A, P2_B
With these values: &P2_A., &P2_B.
That should clear all of 2 but reset A and B back to their current values from the cache before it's cleared.
Or, try this:
Clear cache on page: (don't put anything here)
Set these items: P2_C
With these values: (don't put anything here)
That should (I think) only clear P2_C

What is the cache for?

I know it's a dumb question, but before I clear/empty it, need to know what it does, is for. Thx.

The cache is used to store data off-line, so it is available without having to be downloaded another time. Firefox will contact the server to see if that data is still current. This applies to images and JavaScript and CSS files (additional content). If you clear the cache then everything needs to be downloaded with a next visit to website where Firefox had previously stored data from.

hi,
to clear the cache for a particular user go to the portal admin pages - administer - portal - global settings
navigate to the cache tab
now you can either clear the entire webcache for portal or you clear the cache settings for a particular user.
another possibility (or in addition):
go to the page group settings - access tab - click clear cache.

How to clear cache for items after submitting the page ?

db11gxe , apex 4.0 , firefox 24 ,
hi all ,
i have a non enterable pop-up lov and a report in the same page , and i search with the pop-up item , but the problem is when i click the search button ,
the value in the pop-up is not deleted , and sure i want it cleared after i search ? how to do so ?
thanks

Surely, when you click the search button, the value in your item is required by the report (as a parameter).
Create a button (RESET) with a branch back to the same page and use the clear cache in the branch

How to Clear Cache for an Old Static File in Shared Components

Hello,
I am using Apex 4.1.1.00.23, HTTP Server with mod_plsql, and Oracle Database 10.2.0.5.0.
My situation is as follow:
I have a CSS static file in the shared components that is used in different applications. I recently modified the CSS file, but the changes are not reflected in my applications.
I tried clearing the cache of my browsers, deleting the file from shared components and creating a new one with the same name, and nothing is working.
Using Firebug, I can see that the file used in my pages is the old version of it. Anyone can tell me if the server is caching the file and how can I clear it?
Thank you for your help,
Erick

What kind of document is it (e.g. is this a parsed
HTML file, or a static file)? have you adjusted your
cache settings with the nsfc.conf file? have you
enabled the nsfc report? Are the files stored on NFS
volumes?
Regardless, you can force the cache to be flushed by
enabling the nsfc report, and then accessing the URI
like so:
/nsfc?restart
See the Performance and Tuning Guide:
http://docs.sun.com/source/817-1836-10/perftune.html#w
p17232I tried to to do this. Did n't worked. /nsfc?restart is not working for me. I have IPlanet 6.1 Webserver version. Without having any backend server running, I am getting JSPs displayed from cache!! Please help me out.

How to clear cache for iplanet 6?

I had a situation where a webserver was displaying an old static index.html file after the content had been changed. This went on for sometime, and the web server was even restarted. Seems that the cache was confused.
Does anyone know how to force the cache clean?

What is "Purge Cache" for?

LR2 crashed three times yesterday and I'm wondering if it is time to purge my cache.
But I can't find any information on the preference setting which is found on the "File Handling" tab of Preferences. Would pressing "Purge Cache" help solve the program from being hung up?
Other ideas?
I have already selected "Relaunch and Optimize" under the Catalog preferences. No help. Would it help of I didn't choose full-size Previews? Would it help if I deselected "Automatically write changes to XMP"?
The problem is that the program just hangs. I get the spinning pizza wheel and have no choice but to force quit the program.
I am running LR2 on a Desktop Mac running OS 10.5.4.
The computer has 16 GB of RAM.
I have 80,000 files. All my RAW files are imported and stored as DNG.
Many of my files are quite large, coming from a Canon 1DsMk3.

It purges the Camera Raw cache.
Try it!
What might help is clearing the Previews and regenerating them, but that will take a while

Getting BT To clear cache for my webserver

Hi All,
I host a number of sites from my web server. Since thursday they have intermittently become unaccessible with the message "TCP-IP Error".
So, first port of call was to clear browser cache, try other computers, etc. Still same issue
Next to my webserver provider (Godaddy). They ran a load of checks, & could access all of my sites fine, either when trying on their local machines, or when trying their "out of network machine" to ensure that there was access from an external source.
So, as I look after a number of commercial clients IT systems, I dialled in to one of their servers (who aren't on BT) & tried to access the site from their. Bingo, worked fine.
So, I then ran some traceroute tests, & all looked ok. But still no sites going through the BT connection. So I called back Godaddy who said that I needed to request that BT cleared their Cache.
Question is, who do I call to arrange this? I've spent many lonesome expensive hours on the phone to the wrong people at BT. Is there a section that I can email or telephone to get through to the right person?
Even better, is there a BT employee on here whom can help?

Thanks. BT aren't listening anywhere it seems. The online help chappie, Abjad, couldn't help so got me to call technical help, who after explaining that their DNS server which provides DNS to my home hub hadn't updated in 18 hours (when every other DNS server in the world had managed it), told me he didn't know who to tell about that, so he could do nothing about it.
So, what I did was update my computer's DNS table to include the Google DNS servers at 8.8.8.8 and 8.8.4.4.
Problem solved worked aorund.

How to clear cache for XML data source?

Hi All,
I'm facing a problem loading XML data into Oracle using Oracle Data Integrator. The problem is ODI will cache the data of the XML file at the first time loading the data. And afterwards, when the XML file changed, ODI will load data from the cache.
I did serveral testing on this. If I run the interface in local agent of the designer, I must restart the designer to clear the cache. If I run the interface in an agent, I must restart the agent to clear the cache.
Below is my configuration:
ODI version: 10.1.3.5.0
The technology of the source: XML.
JDBC driver: com.sunopsis.jdbc.driver.xml.SnpsXmlDriver
Does anybody know how to clear the cache of the agent or XML?
Thanks.

Hi ,
Use drop_on_disc or dod in your JDBC URL .
example ,
jdbc:snps:xml?f=C:\mutation.xml&d=C:\mutation.xsd&lf=C:\mutation.log&ro=true&dod=yes
The dod (drop_on_disc) drop automatically the schema when closing the JDBC connection.
dod option must be the last option of the URL.
This option removes the reference to the schema from the driver, and if the schema is store in memory, it also drops the schema. If the schema is stored in an external database (set via db_props), the driver tries to drop the database schema.
Thanks,
Sutirtha
