UI5 negative cache

Hi
I am facing a problem with negative cache and UI5.
"found in negative cache: 'sap.m.Tile' from /sapui5/resources/sap/m/library-preload.json/sap.m.Tile: TypeError: Object doesn't support this action!"
Has anyone ever had a similar problem?
best regards
Thomas Maier

Hi Marc
Tried it a couple of times but still the same issue.

I make a new deploy and the app works fine for 5 minutes, then I get this error again....
Any idea?
Thanks a lot for your time on this thread.
RLS

Hi L. Menon:
Thanks for your answer.
There was no set up of any hotfix or SP.
Something strange is that if I test the app with the "Web Dynpro Administrator console" the apps works fine, there's no class loading issue and there's no error, but if I test it at SAP Portal the error appears.
Thanks.

Hi Sridhar S
thanks for responding
i found the solution, i found that the functions that i was calling (RFC) was not correctly transport to Production enviroment, thats way, the problem was only in production,
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

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,
did you found a way to flush the chache?

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

Counter negative cache hits and long searches

hi my name is sumit.
In my network there is a frame-relay pvc on 7206 VXR router on which 2 T1's are terminated(from S8700 EPABX) and the bandwidth of this PVC is 600 KBPS. we are using rtp and tcp header compression technique(codec g729r8).7206 router is connected to IGX through HSSI cable and there is a IGX to IGX connectivity from INDIA to US. At US site there is a same network. and it is further connected to AT&T cloud. mainly on this PVC there is inbound traffic which comes from US AT&T cloud.
we are facing a lot of voice quality issues and when i use show frame relay ip rtp header-compression.
the counter negative cache hits and long searches rapidly increases
can somebody help me to solve the problem.
and tell me is there any affect on voice quality if these counters rapidly increases

hi Neo thanks for reply.
r u from Datacraft ?
I am also from Datacraft
i have already used this URL. but it gives only one statement about counters.
but i am asking what could be an impact of these counters on voice ?
please reply

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
http://technet.microsoft.com/en-us/library/cc959309.aspx
Here was a thread that asked the same thing, but no resolution:
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:

Invisible note nu00B01000889 "Negative cache"

Hi,
By reading SAP Notes n°1044872 and n°1135138, I remark that the solution of my "negative cache" problem is described in SAP Note n°1000889.
But while attempting to access it, I get the following error message :
Note 1000889
An SAP note with the number requested could not be found.
How can I access this note ?
Any idea would be appreciated
Regards
Arnaud

Most likely the solution in that note became irrelevant, so it was taken out of availability. Or it might be temporarily unavailable.
E.g.: SAP note # 1 still exists, but # 4 is not available
Cheers,
Julius

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

Negative cache - ClassLoader

Hi,
I get this warning message when trying to access my webdynpro service :

Seems that it's a "negative cache" issue but I wonder how to solve it...
I found some posts about this: RFC found in negative cache, Found in negative cache and What's Negative Cache ??.
But I couldn't find my answer...
All I understand is that the "com.company.ayantdoit.models.zayantdroitgetascmodel.Zayantdroit_S" structure is defined twice on the server.
That would maybe be explained by the fact this DC has been duplicated in a new track, with the same name, and same package name. So we now have 2 DCs with the exact same name.
I tried undeploying this DC on the server (so it'd wipe everything out) and redeploying it with the latest version (the one from the new track) but it didn't change anything.
For information, I already tried to transport it again, but it didn't change anything.
Would someone have any idea ?

Well... our issue is repaired now.
Our problem was because of a Transport Request which wasn't present in this environment.
But for those who need to investigate the 'ClassLoader issue', you'll find some answers [here|http://help.sap.com/saphelp_nw04s/helpdata/en/25/724d457ea5ee469e35aa158d75c740/frameset.htm|ClassLoader Reference Viewer] and [here|http://help.sap.com/saphelp_nw04s/helpdata/en/25/724d457ea5ee469e35aa158d75c740/frameset.htm|Working with the Reference Viewer].

Cannot load login module , Found in negative cache?

Hello All,
I am trying out the SSO with Header Variable Login , by adding the UserId into the Header Variable.
I am able to login to the Portal as per the steps given in "HeaderVariableLoginModule" http://help.sap.com/saphelp_nw04/helpdata/en/d0/a3d940c2653126e10000000a1550b0/frameset.htm
There is another extension of HeaderVariableLoginModule called the IPHeaderVariableLoginModule, which allows login only if the request comes from the specified IP address.
But after trying this i am getting the foll error :
Cannot load login module class de.platinion.security.IPHeaderLoginModule.
[EXCEPTION]
java.lang.ClassNotFoundException: de.platinion.security.IPHeaderLoginModule

I have followed the steps given in the document, https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/069eaf4b-0901-0010-6e89-d1fcceebcbf1
but still am getting the same error,
I guess it has something to do with the ClassLoader or classpath coz it gives a ClassNotFoundException, but am not able to find a solution..
Could some1 help me out??
Thanks,
Meghana
