What is the negative cache?

Hi,
I generate various RFC Models that I use in my Web Dynpro. Most of them work fine. But there are some models that throw the following runtime exception:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: com.vw.idm.dbk.model.Zidm_Dbk_Id
Found in negative cache
The type Zidm_Dbk_Id is the type of an output attribute of the RFC.
Does anybody know what this could mean?
Thanks in advance
Helmut

Have you tried restarting the server?
It seems like the classloader caches "misses" when loading classes.
I have seen this error before too.
Regards
Bruno

What is the name "cache" refer to?

What is the name "cache" refer to in the following script?
Is cache a class? But I cannot find it in the Coherence Documentation.
CacheService service = cache.getCacheService();
Cluster cluster = service.getCluster();
Thank you

Thank you very much.
But I think the Oracle documentation: Oracle Coherence Getting Started is not suitable for a beginner. Some aspects are not put sufficiently clear and not in details. Could you recommend some documentations easier and more suitable for a beginner?
Many terms are cited without ant explanations. For example:
thread-local lazy-initialization pattern,
dedicated cache servers,
container connection pool,
threadpool,

What are the negative effects of shutting down often?

I use my computer everyday. Is it the best choice to shut it down every night (when i am sleeping) for:
a. Saving electricity?
b. maintaining battery life?
c. the environment???
And I am sure there are other factors I can't think of now. What are the negatives and positives of using sleep mode? When is it best to shut down?
Thank you all for reading, and answering!

I use my computer everyday. Is it the best choice to
shut it down every night (when i am sleeping) for:
a. Saving electricity?
Nominal as the computer uses very little power when it is in sleep mode. The surge when the computer starts from being off is probably more as the computer is dead and has to warm up and restart everything.
b. maintaining battery life?
Doesn't affect battery life. When the battery is charged the charge circuit turns off and the battery is idle as long as the magsafe is plugged in and powered.
c. the environment???
Letting your computer sleep or turning it off is going to have minimal impact on the environment. See first answer.
What are the negatives and positives of using
sleep mode?
No negatives I can think of. Positives are the computer wakes up right where you were. You don't need to close any programs or stop to make it go to sleep. Either close the lid or use one of the other methods to put it to sleep.
When is it best to shut down?
I always shut down when I am transporting my computer in a bag. Just personal habit. A few people transport it in a bag while it is asleep and have no problems. I also shut it down when I know I am going to be away from it for over 24 hours. Sleep would work just as well just habit.

How do you flush the negative cache?

Hi all,
I am working with NetWeaver 2004s SR3 SP14 on SuSE 10 with Oracle. I wrote a custom login module and was trying to get SAP to load it. At first I made some reference mistakes (in provider.xml under the references tab) and it wouldn't load. Then I fixed the reference errors and tried to get it to load again and it still wouldn't load. I just keep on getting the error message:
[EXCEPTION]
{1}#2#com.mycompany.dc.netweaver.MyLoginModule#java.lang.ClassNotFoundException:
com.mycompany.dc.netweaver.MyLoginModule
Found in negative cache
I shut down and restarted SAP several times (using stopsap and startsap) and undeploying and redeploying my login module (the fixed version), but still, SAP refuses to load my login module because it is in the "negative cache".
If I keep the code the same, but change the name of the Java class and component name in provider.xml, then SAP happily loads my login module.
So I can work around the issue, but it is really annoying to change your configuration every time you make a mistake with the references... So I was hoping that someone would know how to flush the negative cache. Do I have to go into the database to do it?

Hi Katrina,

What is the HTTP caching flowchart/logic in Firefox?

Hello,
I am configuring a reverse HTTP proxy and I am trying to optimize it as much as possible. I found the following article which was written on Oct. 9, 2002 and it describes the HTTP caching logic in Firefox.
http://www-archive.mozilla.org/projects/netlib/http/http-caching-faq.html
However, the article is pretty old and I don't think that Firefox uses the same flowchart in the latest versions of the browser. Do you know how exactly Firefox caches certain object. What I mean is does FF check the Cache-control header first and then the Expires header and finally the Last-Modified. What happens if there are both Cache-control header and Expires header?
Kind Regards,
Daniel K.

WebLogic Server is a single java process, that has two listen ports, one SSL
and non-ssl.
These two ports use protocol discrimination to handle multiple protocols on
a single port.
NON-SSL --> http, t3 (proprietary rmi protocol), iiop
SSL --> https, t3s, iiops
So WebLogic comes with a build in Webserver. Or you can use a third party
webserver in front of WLS with plugin to proxy to WLS.
See;

What does the "Only cache local content" box do under Caching Server?

Just upgraded to Mavericks server, but I don;t understand what the "Only cache local content option" does? Does that mean it caches content on an on-demand basis, or dowloads all availavle updates?
Thanks!
Joel

https://help.apple.com/advancedserveradmin/mac/3.0/#apd5E1AD52E-012B-4A41-8F21-8 E9EDA56583A
I suppose it's hidden in the Key 'PeerFilterRanges'
When PeerFilterRanges is boolean true, the caching server does the same as the above but uses the ListenRanges rather than the PeerFilterRanges value.

Working on two machines - what about the media cache ?

I'm a long time user of FCP just getting my head around Premiere Pro CS5.5. I quite often work on the same project at work and at home. With FCP I simply duplicated the media onto another drive and just transported the project file on a flash disk - obviously rendering of effects would have to be done locally.
Now with Premiere I notice there's the media cache which, as far as I can tell, is not necessarily anything to do with rendering and effects but related and applied to every clip.
So my question is, will the media cache have to be built from scratch on each machine every time I move the project file ?
If so, is there a way to avoid this so that I wont have to wait for it to build the media cache ?
....or on a 30 minute film with 15 hours of original media will this will this be a quick process so as not to be a problem ?
I suppose what I'm really asking is how can I easily work on the same project in different locations ?
Any help appreciated.

At the moment my media cache is in my user library folder on the system drive.
I would avoid using the system drive for media cache files.
The best would be to have a separate, identically named drive
(D for example) for your media cache.
If you use an external drive for your media, make sure that
you assign the same drive letter to this drive on both systems.
... and then duplicate the lot onto another drive ?
I have never tried to wholesale copy media cache files from one
system to another... preferring to allow Premiere to generate a
cache for each system.
One other thing. Suppose I capture some more media at work, can I just copy this media into the same location on my home drive and then will the media cache on my home machine just update the new media ?
Yes.

OSX 10.9.4 What is the best cache cleaner?

I have a MascBook Pro with 16GB of memory. My file cache is using 1.34 GB of memory. What is the best program to use for cleaning file cache?

None.
Apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, TuneUpMyMac, MacCleanse or anything like these apps, installed on your Mac, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.
Plus, these type of apps aren't really necessary OR needed. They really aren't.
There are manual methods to clear off unnecessary data off of your Mac that are safer and you have complete control over your Mac and not just leave a piece of auto cleaning software in charge of clearing off data off of your Mac. Their potential of causing OS X issues outweighs the implied good and benefits these types of hard drive or memory "cleaning" apps are written to do.
These types of system 'cleaning" apps are very poorly written and are really a scam to rob newbie and novice Mac users of their hard earned cash for a poorly written maintenance program that will do much more harm to a perfectly normal running OS X system than the good that the app developers purport these types of apps will do.
Plus, the software companies that write these apps make it hard to easily uninstall these apps if something DOES go wrong and these apps work in a way where you have no recovery or revert function to return your Mac back to its former, working state in the event something does go wrong.
It is best to never, EVER download and install these types of apps.
The risk to your system and important data is too great a risk!

List of DNS Negative Cache

Hi Folks
I'm having problems with what I believe to be intermittent negative responses for a host from DNS servers that we forward external queries to and those negative responses being cached.
Because of the intermittent nature of the problem every time it is reported I have not been able to carry out a query on the downstream DNS servers that has not produced a positive result.
I would like to know if it is possible to see if negative responses for this specific host are being cached on our DNS servers.
Thanks in advance
Kevin

You can possibly use DNSCMD, but I'm not sure if it will display negatively cached data. Have you tried using ipconfig /displaydns on the client to see what it negatively cached? And I'm not sure that will work. I can't reproduce the problem, since
none of my customers have this issue.
Keep in mind, [quoted from http://tools.ietf.org/html/rfc2308]:
"Negative caching was an optional part of the DNS specification and
   deals with the caching of the non-existence of an RRset [RFC2181] or
   domain name."
"[...] however had a fundamental flaw in that it did not allow a name
   server to hand out those cached responses to other resolvers [...]"
So my feeling is there are non-existing records in some of your DNS servers, or incorrect SOA records, or lame delegations. If your organization is that large, and DNS was not designed properly (all DNS servers in an org must have the same exact reference
to all records or issues will results, especially with AD), then I can see this may occur. So in reality, once you determined what data is negatively cached, the best way is to use DIG or nslookup testing directly against your forwarders for the records
that you believe are negative lookiong for NXDOMAIN responses (which are the records that have been negatively cached).
It may have been possible that Negative Caching was set on *some* of your Windows DNS servers, but not all. That will definitely cause problems. That's done by setting the
NegativeCacheTime to something really much higher than the default 300 seconds (15 minutes). If you are an admin and have access to those machines, you can take a look at that setting in the registry remotely.
Configuring Caching and Negative Caching

Windows DNS Server Negative Cache
"So how do I display what info is in the negative cache? From the command line…"
http://blog.joeware.net/2006/08/12/522/
Further, if your org is using ISA or TMG, and they've set negative caching on those servers, then DNS has nothing to do with it! Check this article out:

Hi Sridhar S
thanks for responding

i made a new transport with all my function in abap and sent it again to production and that solve my problem that i have about the negative cache.
thanks for the help

Custom LoginModule not found, error "Found in negative cache"

Hi all,
I am working with NetWeaver 2004s SR3 SP14 on SuSE 10 with Oracle. I am
writing a custom LoginModule and I get this error in the default trace file when my
sample app tries to use my login module:
[EXCEPTION]
{1}#2#com.mycompany.dc.netweaver.MyLoginModule#java.lang.ClassNotFoundException:
com.mycompany.dc.netweaver.MyLoginModule
Found in negative cache
The class name for my login module is: MyLoginModule and it is in library:
MyLoginModuleLibrary (so the name of the library project in Developer
Studio is MyLoginModuleLibrary and it is the component name in
server/provider.xml for that project). MyLoginModule requires the use of
classes in another library also written by my company (called
mycompany_libs). To complicate matters, mycompany_libs uses JNI. I tried
adding the JNI library directory to the LD_LIBRARY_PATH shell variable
(set before running startsap in the sidadm user's shell). Though I
could find few references to developing using JNI (so if someone out there
has references for using JNI with Netweaver, it would be great, and very
helpful if you would post them).
I was able to successfully deploy MyLoginModuleLibrary and mycompany_libs.
I put the following in the property: LoginModuleClassLoaders in the
security provider properties:
library:mycompany.com~MyLoginModuleLibrary,library:mycompany.com~mycompany_libs
(Note: I changed the provider name server/provider.xml to mycompany.com
for both libraries: MyLoginModuleLibrary and mycompany_libs and that is the
reason why I have the "mycompany.com~" prefix before each library name.)
I added mycompany_libs to the references in server/provider.xml for
MyLoginModuleLibrary. The references look good in the ClassLoader viewer.
But I still get this error. I've restarted the server several times to
try to clear the negative cache (using stopsap, then startsap), but to no
avail.
One thing that I find interesting (and it could be a possible clue to the
problem) is that neither library:mycompany.com~MyLoginModuleLibrary nor
library:mycomany.com~mycompany_libs appears in the ClassLoader name
or in the References in the error message in the log file. I don't know why not
(I would guess that both of these entries should be in the references and Class
loader name in the log file).
Any ideas?
-- Katrina

I tried 2 tests:
(1) I kept all names the same, but removed all of the complexity from the login module. This new login module would just return true when login() is called and add the principal: "sillyuser at testing dot com" to the principal list when commit() is called.
(2) Just like the first test (i.e. a very simple login module that does no real authentication at all), except I changed the name of the library, the LoginModule class, and the jar file. The provider name was still mycompany.com. I corrected references in LoginModuleLibraryLoaders property in Security Provider.
Test (1) had the same error (ClassNotFoundException "Found in negative cache"), but test (2) worked! It was able to load my login module and I was able to see the trace entries in the log file.
So, I guess the problem is that the "negative cache" is not getting cleared. Anyone know how to clear it?
Thanks,
Katrina

What's the diff btwn: Sync only chkd songs & videos and Manually manage them?

There's no way to logically logic this out. Sounds like a Mensa question. OK, the full text:
For iPhones, iPads, I assume iPod Touch too (don't have one), when you set your sync/backup prefs in iTunes, under Summary > Options: checkboxes #3 and #6 read:
Sync only check songs and videos
Manually manage music and videos
To confuse more: if I cycle thru the tabs after plugging an iDevice (Apps, Tones, Music, Movies, TV Shows, Books, Photos), except for the Apps page, each has a checkbox at the top of each page such as: Sync Tones, Sync Music, Sync Movies, etc.
Checking any of these boxes allows you to "manually" then check the content you want to move on to your iDevice, and of course unchecking an item on your iDevice will remove it upon Sync/Backup
Back to Summary > Options:
I thought I'd experiment:
I had #3 checked plus the Sync boxes on the Music, Movies, TV Shows, Books and Photos (from iPhoto). I unchecked it and nothing changed.
Then I checked #6. Oooops. #3 grayed out, and all my checks on each page unchecked.
Worse, going to the Music page, where you can see all your songs in your iTunes Library, without the Sync Music checked, the page is blank. Checking it again brings forth a very scary alert
So.. until I figure this out, seems my experimenting may cost me to cleanse my iPad Air of all it's music. Not the end of the world, I just have to recheck what I had on it from Library and reSync.
Adages a side (curiosity killed the cat comes to mind)
I have to assume there are differences, even if just nuances between all these options for managing your stuff on your iDevices. These options have been in iTunes for as long back as I can remember. Unfortunately today I was backing up readying for iOS 8 and got curious, and here I am. Woe as me.
I'd sure like to understand all this, and know what should be checked if you want to manage your media and apps manually.

How to undo unwanted changes like mine above:
I luckily opened my iPad Air in the left column of iTunes where Playlists are and clicked Music (still experimenting, will I EVER learn?) but I got a message noting that I had made a change and did I want to Apply, which as you know from above I didn't. I clicked what ever the negative was (No, Cancel, etc.) and my settings were all restored as before I started checking and unchecking. Even my Summary > Options #3 was checked as before starting all this.
Whew. Saved.
But I still as I bet many others want to know how to manage the manage checkboxes

What is the diffrence between cookies and cache, is it safe to remove cache?

what is the difference between cookies and cache , is it safe to remove cache ? . I had cleaned cookies many times but I have not removed cache , does it goes on increasing day by day ? please let me know

Cookies are small files that contain information useful to a web site -- such as password, preferences, last date visited, etc. You may remove the cookies that you don't want adn since some of them are a privacy issue, many people remove them all.
Cache is just a collection of data downloaded to help display a web page. After you leave a site, much of the cache is left on your computer and is no longer needed. You can always remove the cache because it will be replaced as needed.

What is the negative cache?
