What benefits do I lose by clearing cache?

I've been advised to "delete Cashes.db" and "to Empty Caches" as steps in speeding up by slow Safari? What advantages to having these do I lose by doing either or both of these; that is, are there any important functions, such as slower speed for a while, that I lose by doing so? Thanks.

Caches store frequently accessed data so it doesn't have to be re-loaded from the Internet or HDD both of which are slower. Deleting caches will only cause a short-term slowdown until they are re-populated automatically. Deleting a cache is only necessary if it contains old data that keeps loading in place of new data, but this is a rare occurrence.

IE work fine but I cannot get Firefox to connect even after clearing cache, reseting Firefox and re-installing, what do I do next?

Firefox recently tried to update, after that it no longer connects to the Internet. IE works fine. I tried clearing cache, reseting and re-installing. What do I do next to fix the problem.
Thanks...David Puzycki

hello david, please see [[Fix problems connecting to websites after updating Firefox]]

What to do when Clear Now button stops working - it no longer clears cache?

After browsing, I would, most times, clear cache by going to options and then pressing the Clear Now button. This always worked before. But, today it won't do anything.
Are there other ways to clear cache or to delete temporary internet files and clear any data or passwords posted to gain entry to certain websites? - matt

Saxman,
I think their parachute effort was System Preferences > Bluetooth > Advanced... > "Open Bluetooth Setup Assistant at startup when no input device is present". In your case the keyboard was there so it probably didn't open. Now that you have a mouse and trackpad, you should have at least one of them connect, so that's a bit of insurance.
I would also add those devices to bluetooth favorites located under the gear icon below the list. Select "show more information" if you don't see the favorites selection.

My Safari keeps crashing even after clearing cache/history/etc. Help?

I have tried resetting, clearing cache, and erasing the history. I'm not sure what is going on with my Safari. I did notice I kept getting those "Mackeeper" popups, but I never downloaded it or anything. Could this be the issue? I have looked through other threads and couldn't find a solution to the problem. Thanks!

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the name of the crashed application or process in the Filter text field. Select the messages from the time of the last crash, if any. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in the Console window, look under User Diagnostic Reports for crash reports related to the process. The report name starts with the name of the crashed process, and ends with ".crash". Select the most recent report and post the entire contents — again, the text, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

How to clear Cache in Safari

Quit Safari.
Click out on your desktop somewhere to get Finder menu on the top menu bar. Then look over to the right, and select the "Go" menu while holding down the "Option"button. You will then see an option for "Library" right under your home folder on that list.
That is your hidden Users Library. Open that Library, go down to Caches. Open that, and then look for apple.com.Safari. Take that file to the trash.
Restart Safari.
I tried it, I do not know what the consequences are yet

It''s a bit drastic, but that clears Safari cache. There's another way of clearing the cache:
1. Open Safari, go to Safari menu (on the menu bar) > Preferences > Advanced, and tick "Show Develop menu in menu bar".
2. Close Preferences, and go to Develop menu > Delete cache

Unable to clear cache in 3.6.10

Running 3.6.10 and not able to clear cache either manually or automatically. I don't know what else to do as I've done everything the help section says to clear the cache.
I was also unable to install Skype due to a cookie problem. I'm hesitant to reinstall Firefox due to all of my bookmarks.

Did you check that on the about:cache page?
* Make sure that you not run Firefox in [[Private Browsing]] mode
* You are in Private Browsing mode if you see "Tools > Stop Private Browsing", possibly grayed
Are the disk cache and the memory cache enabled?

I'm having to clear cache and cookies daily to have certain favorite websites appear normally - why does that intervention only work for a short period?

I'm having to clear cache and cookies from the tools menu sometimes 2-3 times daily in order to make certain websites appear normally. The websites will have mostly script, which will be placed in columns, and very little in the way of graphics, maybe just a still picture of two. After I clear the cache and cookies, the sites go back to normal, but maybe after a few hours when I go back to the website it will re-appear as described above. The url below is the most commonly affected but it also happens on others like Yahoo news.

In order to uninstall a possibly unwanted extension, please do the following:
#From the Firefox window click the Firefox button at the top left and select ''Add-ons'', or, if the Firefox button is not shown, click the ''Tools'' menu and click ''Add-ons''.
#Once the Add-on Manager has opened in a new tab, click the ''Extensions'' button on the left side of the window.
#You should now see a list of your installed extensions on the right side together with buttons on the right side of each extension.
#To remove an extension from Firefox, simply click the ''Remove'' button on PDF Viewer (what is this?). You should see a message that informs you about the successful removal of the add-on.
#Note that some add-ons require a Firefox restart to be removed completely. To perform a Firefox restart after the add-on removal, click the ''Restart now'' link in the message.
You can find further information about uninstalling extensions in the following articles:
[[Disable or remove Add-ons]]
[[Remove a toolbar that has taken over your Firefox search or home page]]

Clear Cache-Single Page Item

I need to clear the cache for a single page item. This is what I have done:
- Created button call Reset Appt Time
- Created Process - Clear Cache for items, Source has the page item I need to clear - P3_APPT_DT_TM
- Created Branch - so that when Reset button is pressed it branches back to same page (3)
Everything works, but the cache is cleared for all the items on the page not just the one page item I specified.
Please advise.

Hi,
I am not sure if you could clear cache of a single item, but you can initialize any item to null or any values, look for the Action box of Page Branch, (set these items and set these values ).

Clear cache in the session

In my application, there are multiple tabs created. Each tab has a different functiionality. When I enter some value in the first tab and after processing the page, if I navigate to another tab and again come back to the previous tab, the value entered in the text field is still displayed.
My requirement is to make the contents of the text field null when ever I navigate to that page.
In short within a session, the values entered in the text fields are not cleared when navigating between pages.
Any ways to achieve this?
Regards
Amit.

U have clear cache option in tab entries details.. set it to pages which U want f.e. 3,7 - will clear cache of page 3 and page 7.

Clear Cache of a Page using Tabs

Hello,
my problem is, that i want to clear the cache of a page, when the user accesses this page by clicking a tab.
So my Page has six items, which are used to search people in a db.
Under the items is a submit button, which submits the values in the items and the same page is loaded with the search result.
But when i go on another page and click on the tab of the "search-page" the result is still there.
Because of the submit button i can not create a process which clears the cache when the page is loaded....
I hope you understand my problem,
Thank you,
Tim

This is not possible using the built in Apex tabs. Apex tabs are meant to quickly switch between pages with all your session state intact.
You can do what you want if you use a List instead of tabs. You have full control over List entries and you can clear cache for the list target page, set other items as needed (you can control the full f?p= URL)
Hope this helps.

Command line to clear cache?

JRE 1.4.2_04
I need to clear the cache on about 2000 machines and would prefer not to visit each one physically. Is there a command line parameter I can feed to jpicpl32.exe to trigger the cache clear? I've seen several threads asking about this but it does not seem to have been addressed as other solutions were found. However, I have no access to the server side of the application, so my only option is to clear the cache.
can this be done?

Hi,
OBIEE Cursor Cache clear from Dashboard Java Script
OBIEE Cursor cache is normally cleared from the Administration - Manage Sessions Screen...
Here is a way that a piece of java can be embedded into a dashboard and call an xframe so you cant see it being called and clear the OBIEE Cursor cache - Presentation cache in effect.
1. Just insert a text box into Dashboard - Tick the "Contains HTML Markup"
2. Paste the script below into the text box
<script language="javascript">
document.write(
"<iframe width=0px height=0px src=" +
document.location.href.match(/^[^?]+/) +
"?ManageSessions" +
document.location.href.match(/&_scid=[^&]+/) +
"&Action=CloseAllCursors&Done=saw.dll%3fSessions',{ensureFreshUrl:true});return false;')></iframe>"
</script>
Voila - when ever you click on the dashboard or refresh it the cursor cache will get cleared.
Please refer the below links for more information on this.

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

Tried everything, cannot get firefox to open new tab rather than new window. set options, cleared cache, rebooted. win 7 firefox v26

Win 7 64bit desktop.
Set tools --> options --> tabs OPEN new windows in new TAB instead checked.
apply/save .. tried from there, tried exiting firefox. tried clearing cache.
what else???

Hello leelassow, '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
[[Image:FirefoxSafeMode|width=520]]
''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.
