"Work offline" button went away from taskbar and cannot recovered after performing CSC cache clear

Hi All,
Some Windows 7 Pro users reported DFS folder mapping issue, CSC cache was cleared by following below KB article.
- On a Windows Vista-based or Windows 7-based client computer, you can still access offline files even though the file server is removed from the network
support.microsoft.com/kb/942974/en-us
After CSC cache clear, I am not able to see "Work offline" button from file explorer taskbar.
I was recommended to look for "always available offline" by right mouse click, but the item is not available for my platform.
- "Always available offline" option and Offline Files tab disappeared in folder options

So far I tested with 4 of workstation and all of them has no "Work offline" button or "Always available offline" item with right mouse click.
We are disabling IPv6 and wondering whether this is causing not to recover "Work offline" button or not...

How can I make MUSE upload one png that it overlooks? Cache cleared & shows in Preview

MUSE uploads everything to BC except an inport png. I cleared the cache, it shows inPreview, no conflicts noted in Assets and the Browser reflects any other changes I make to the page. The space for the image is missing online and the entire page moves up to fill the space

Thanks for getting back. I had a deadline so I gave-up trying to make that (great) extracted image work and deleted it from my system -frustration. For what its worth, MUSE displayed the png in Design/ Preview/ Plan & provided an empty space for it when published. Besides this quirk, MUSE has been a great.

KM Cache and iView Cache - Pros and Cons

Hi All,
Can anyone tell me which Caching mechanism is better - KM Caching or iView Caching ?
What are the Pros and Cons of KM Caching and iView Caching ? Which type of caching is recommended ?
Any kind of help is appreciated.
Regards,
Adren

Hi Adren,
As to my understanding, with Portal Cache, we can achieve the following:
1. Significant improvement in the interface response time
2. Unnecessary, additional page generation (re-rendering) is avoided when you call a portal page
3. Web browser-like caching for server-based, dynamic pages in the Web (such as the BW Application Web)
Cache monitor to monitor the current status of all active caches in your system landscape. The data displayed in the cache monitor can be used for evaluations
KM cache might eb better than Iview cache.
Please check the below links we might get soem info about the type of cache which is preferable.

Cache.clear()

Hi,
     I have a question about the behaviour of cache.clear().
     I have a cache that is read very heavily and inserted into at a much lower rate. There is an event that occurs periodically which means that all the keys (& values) in the cache become useless. We will never lookup the old values again.
     I would like to get rid of the "useless" values at the point that this event occurs. Is it wise to use cache.clear() in this context? I understand that clearing means that all the keys in the cache must be locked while the clearing occurs, but I'm not 100% clear on the details of this.
     Given that this cache is read so heavily, I am concerned that clear() might be "stopping the cluster" while the keys are deleted.
     But then again our application will never try to lookup an "old" key after the "clear" event occurs. So if Coherence is clever enough to be locking only the "old" keys then there wouldn't be a problem anyway.
     Any thoughts or light you can shed on this would be much appreciated.
     Thanks,
     dgj

Hi,
     You can certainly use cache.clear(), but, you are right - on a very large caches it may be slow. If this event is periodic you can configure expiry-delay (see local-scheme).

For about the past week, Facebook has been taking forever to load (or just not) on my mac (OSX 10.5.8; Safari 5.0.6). Other sites are fine. I routinely empty the cache, clear history, cookies, etc. each time I shut down. Suggestions?

For about the past week, Facebook has been taking forever to load (or just doesn't) on my mac (OSX 10.5.8; Safari 5.0.6). Other sites are fine. I routinely empty the cache, clear history, cookies, etc. each time I shut down. Suggestions?

I don't use Facebook, but I can say that clearing the cache every time you shut down is excessive - unless you're sure the cache is corrupt you should leave it alone. It exists to speed up your browsing experience by loading frequently requested items from your drive rather than downloading them fresh from the internet each time. So, I would say stop clearing your cache and see what happens.
As for clearing cookies: I'm not sure what method you currently use, but I would recommend you download and install CCleaner. It's free, and allows you to build up a list of cookies that you want to clear and those you want to keep, before deleting them.
Both of these may help speed things up by reducing the amount of work Safari has to perform whilst browsing. Regardless, I'd say that, unless there's a reason you've not mentioned for performing the "purging" that you do, making these two changes should see improvements in general web browsing if not specifically when loading Facebook.

OBIEE Cache clear and refresh of reports from DAC

Hi All,
I have an existing process where OBIEE cache clear and Dashboard report refresh is happened from DAC.
But the issue is both do not happen parallely, the both tasks are kept in single text file and they are called from a batch file from DAC. Below is the code
nqcmd -d AnalyticsWeb -u Administrator -p SADMIN -s D:\OracleBI\server\Bin\PurgeAllCache.txt
So I want to make them run parellely so that Cache clear and refresh of reports happen parellely. In order to achieve do I need to create seperate batch files or can I manage by changing the above code.
Please Suggest.

Can you share the code in the file PurgeAllCache.txt
There might be some issue with code, make sure you use ';' for each statement.
or else use 2 files and 2 commands to execute them.
Pls mark if helps

IView Caching BrowserOnly setting

Hi,
Can anyone shed some light on the BrowserOnly setting that is available in the Load properties of an iView? It does not seem to do anything in particular and all i can find on SAP Help is this....
http://help.sap.com/saphelp_erp2004/helpdata/en/75/e3fc40b3c7fa6fe10000000a1550b0/frameset.htm
Apparently it is supposed to allow caching only in the browser cache and not in the PRT cache... but the iViews I am testing are not stored in the Browser Cache for some reason....
Any experience on this would be a great help.
BRgds,
Simon

Make sure:
1-your the local cache on your browser is not full
2-your system wide setting is not over riding the iView level setting - system setting can be found here:
System Administration > System Configuration
from Detailed Navigation: Service Configuration
more details are found here:
http://help.sap.com/saphelp_nw04/helpdata/en/1c/3f1c409ce22402e10000000a1550b0/content.htm
We wanted to do the opposite, to make the iViews not cache on the browser which contain sensitive data, particularly due to users that share computers. So we had to change the iView cache property to None. The BrowserOnly setting should be used with iViews that don't need to change often for improving performance of the Portal.

Setup event table cache clear for - Essbase cube table

we have event polling table for clearing the cache now having issues in setting up for essbase physical cube tables.
1. we have structure of hyperion like this for physical cube table "CONSOL"- where schema is empty.
"Hyperion"."CONSOLX".."CONSOL"
2. Event polling table is in different database/connection
When the event table is populated without schema, polling actually looking for the table in the database configured for the event pool connection pool and not "hyperion".
*[55001] The physical table Hyperion:CONSOLX:Event Polling:CONSOL in a cache polled row does not exist.*
When i read in some blogs...I understood its working as expected(when something is null it looks in event polling database)
Has anybody configured event polling for hyperion cubes table cache clear ?
Thanks
Ayaps

what is your insert statement in UET table?
Looks like you are missing one value out of 4 required. Thats why it is considering Event Pooling in between. As you have event pooling table in different physical database, you have to fill DbName,CatalogName,SchemaName and TableName in the UET tables.

BW Cache-Clear automatically via Report ?

sometimes, we had a (maybe) cache-problem?
a user starts a query (via BW-portal) with date 26.01.2012
the result is the same report but from date 25.01.2012
after a manually cache-refresh
a user starts a query (via BW-portal) with date 26.01.2012
the result is the same report with the correct date 26.01.2012
is it possible to force the cache-Clear or Cache-refresh automatically once a day e.g. with a report ?

o.k. - i just had enough time now to search the forum ........
I created an ABAP with usage of function RSR_CACHE_CLEAR_ALL_CACHES
and made an SM36 Job-Entry as every day clear-Job.
Done.

Problems with cache.clear()

Hello!
We are having some problems with cache clears in our production cluster that we do once a day. Sometimes heaps "explode" with a lot of outgoing messages when we do a cache.clear() and the entire cluster starts failing.
We had some success with a alternate method of doing the cache clear where we iterate cache.keySet() and do a cache.remove(key) with a pausetime of 100 ms after 20000 objects until the cache is empty. But today nodes started failing on a cache.size() before the removes started (the first thing we do is to log the size of the cache we are about to clear before the remove operations start).
We have multiple distributed caches configured with a near cache. The nearcache has 10k objects as high units and the back caches vary in size, the largest is around 300k / node.
In total the DistributedCache-service is handling ~20 caches.
The cluster consists of 18 storage enabled nodes spread across 6 servers and 31 non storage enabled nodes running on 31 servers.
The invalidation stategy on the near caches is ALL (or, its AUTO but it looks like it selects ALL since ListenerFilterCount=29 and ListenerKeyCount=0 on a StorageManager?)
Parition count is 257, backup count 1, no changes in thread count on the service, service is DistributedCache.
Coherence version 3.6.1.0.
A udp test sending from one node to another displays 60 megabyte/s.
Heapsize for the Coherence JVMs, 3gb. LargePages is used.
Heapsize for the front nodes JVMs, 6gb. LargePages is used.
No long GC-times (until the heaps explode), 0.2-0.6 seconds. CMS-collector.
JDK 1.6 u21 64-bit.
Windows 2k8R2.
We are also running CoherenceWeb and some Read/Write-caches, but on different coherence services. We are not doing any clear/size-operations against caches owed by these services.
Looking at some metrics from the last time we had this problem (where we crashed on cache.size()).
The number of messages sent by the backing nodes went from <100/s to 20k-50k/s in 15 s.
The number of messages resent by the backing nodes went from ~0/s to 1k-50k/s depending on the node in 15 s.
At the time the total number of requests against the DistributedCache-service was around 6-8/s and node.
To my questions, should it be a problem to do a cache clear with this setup (where the largest cache is around 5.4 million entires) ? Should it be a problem to do a cache.size()?
What is the nicest way to do a cache.clear()? Any other strategy?
Could a lock on a entry in the cache cause this problem? Should it really cause a problem with cache.size()?
Any advice?
BR,
Carl

Hi Charlie,
Thank you for your answer! Yes, actually we are using a lot of expiry and many of the items are created at roughly the same time! We haven't configured expiry in the cache configuration, instead we do a put with a expire.
Regarding the workload, compared to our peak hours it has been very low when had problems with the size and clear operations. So the backing tier isn't really doing much at the time. That's what has been so strange with this problem.
The release going live today has PRESENT as near cache invalidation strategy. We remove as much of the expire as possible in the next.
BR,
Carl

Constantly 'not responding'. Why? Cache cleared, history cleared, this happens all the time!

My Mozilla Firefox is constantly 'not responding'. I have cleared the cache, cleared all history, run disk cleaner, run defrag, yet it continues to be a problem. It also 'can't find' many common sites like yahoomail. What is wrong? It shows as being completely updated.

Hi,
Is the circle on the tab green and rotating clockwise or grey and anti clockwise when 'not responding'?

Cache clearing during high planning usage

Hi
I was going through some performance notes for Integrated Planning and one of the suggestions there was Cache clearing during high planning usage.
What does this mean and how can it be performed
Thanks
Rashmi.

Hi Rashmi,
what is the note you mentioned?
The OLAP cache usually is a mechanism to improve performace, though there might be case where the 'administration' of the cache creates some extra costs that may lead to better results without using the cache. But there are no general guidelines when this might happen. This heavily depends on the data model, queries and data access pattern.
In planning - as explained in note 1056259 - caching might be used via the planbuffer queries. These are system generated queries involved when input ready queries read transaction data. The query name is CUBE/!!1CUBE (aggregation level on an InfoCube) or MPRO/!!1MPRO (aggregation leve on a multiprovider). Via RSRCACHE (or also via RSRT, button 'Cache Monitor') you can check the caches. Via RSRT you can also deactivate the cache for a query or planbuffer query. You may play with these settings.
Caching is working best if the same data are shared for different users. But in planning different users sharing overlapping data in change mode will lock each other. So one might share actual data. One also might try to do a cache 'warm up' using a filter that creates caches that can be reused by different users. This would mean that plan users have non-overlapping selections but the warm up would be done before with a union of some of the filters used by the plan users. But how to do this in detail and whether it is worth the effort can only be answered in the customer project.

Gregor

Cache clear history

how and where can i see the cache clear history time.
lets say,if i have cleared total cache 3 times today and 4 times yesterday,where can i see the todays 3 times time and yesterdays 4 times time.
Thanks in advance

This information is captured in NQQuery.log file @ OracleBI\server\Log
You will find the lines like:
====
Administrator:fffe0000:fffe0001:----2011/09/22 12:26:17
-------------------- Cache Purge of query:
SET VARIABLE QUERY_SRC_CD='Report';SELECT TIME_DIM."YEAR" saw_0...
=======
This will give the timestamp for individual SQLs BUT all the cache purged together will have same timestamp..
Hope its clear...Give a try and do some unit testing ..
