BW cache mode under RSRT

Hi all,
Which cache mode is better for good performance? I went thru help.sap.com and I got more confused.
If possible please let me know the differences in a plain english.
Regards,
N.S.

Hi N.S,
Go over pizzamans post so that you can understand what exactly the factors to decide for cache mode and then you can decide which mode to use according to query performance.
If you go to transaction RSRT and in there the query properties then you can select the cace modes.
0.Cache inactive.
1.Memory cache without swap.
2.Memory cache with swap.
3.Persistant cache per application server.
4.Persistant cache across each application server.
Generally cache mode does increase performance of queries but you should know what cache mode to apply to which queries. There is a standard rundown I am giving you I hope it will be useful in you scenario
1. If your data changes frequently: Then use the 0 mode.
2. If there are many users and many navigations based on that query: then u can use any mode except 0.
3. If you have large result set in your query (E.g HR): then you can use 2,3,4 mode(I recommend4) but 0 and 1 may not be useful.
I hope these insigts are useful.
Regards,
Nikhil

Outlook cached mode, shared calendars, permissions and sync errors

We have the following environment -
Exchange 2010 SP2, no public folder DB; Outlook 2010 sp1 cached mode.
under very specific circumstances, but unfortunately a common circumstance, we're getting sync errors -
15:59:56 Synchronizer Version 14.0.6126
15:59:56 Synchronizing Mailbox 'Nigel'
15:59:56 Synchronizing server changes in folder 'Naomi - Calendar'
15:59:56 Downloading from server 'outlook.cri.camres.org'
15:59:56 Error synchronizing folder

15:59:56                                 You do not have sufficient permission to perform this
operation on this object. See the folder contact or your system administrator.

15:59:56 Done
This occurs if Naomi shares her Calendar with me, without granting me read "Full Details", if she changes the permissions and allows me to read Full Details, the sync error goes away.
It's repeatable, i have tested it with a few users sharing calendars with each other, and changing permissions.
The peculiar thing is that Naomi is in My Team, so her calendar is listed under Team Calendar, I get no sync errors, it's only when I add Naomi's Calendar as a Shared Calendar and don't have read Full Access permission that the sync errors appear.
User's don't necessarily want to give Full Access to their Calendars, so that's not really a viable work around for us, this smells very much like a bug with outlook, is anyone else seeing this?

Hi
Thanks for sharing

Cache mode for specific query

Hello BI guys,
This is Calvin from Korea. We are implementing BI 7.0 and have some severe performance problem. For some queries they don't use cache mode, even though the global cache are used.
When I checked these kind of queries by performance information in RSRT, I got following message,

hi Dong Suk Choi ,
the technical information which u have furnished clearly says that the settings
that u have made does not enable the query to use cache.
u can enhance cache by customizing the inforovider or in the transaction rsrt
even if the concerned query does not have required settings u can make them in rsrt tcode.
goto rsrt set the read mode and cache mode as u wish, however default settings would give optimum performance.
and run the query.
in the rsrt screen a push button execute + debug enter that and unmark the check box do not use cache.
hope this helps.
reward points if helpful.
bye.
under properties tab u can give the query settingMessage was edited by:

Questions on cache and general RSRT settings for plancube

Hi,
we would like to:
1) set request status 1 in RSRT for our planqueries, in order to automatically refresh the query after executing a planfunction (problem we have now is that the results of a planfunction are not automatically updated in the query. Only when doing something else like executing other function, saving, check locks, ... the results are visible).
2) activate delta cache for our planqueries
we have read OSS note 1136163 on RSRT settings. It says:
Aggregation level "A" is implemented internally by the automatically created query "P/!!1P" (plan buffer query). This query acts like an InfoProvider. It reads the data of the database or provides the data from InfoProvider "P", it adds the data of the delta buffer "Dp" (or the delta buffer Dpi if P is a MultiProvider with several PartProviders Pi that can be planned) and transfers the data manager as data of the InfoProvider "A" of type "ALVL". The query "P/!!1P" can use aggregates and the cache; this is exactly like each normal query in "P". If "P" is a MultiProvider, it is useful to set PARTITIONMODE to "1".
              For the query "P/!!1P" that is created automatically for an aggregation level or for all aggregation levels using the InfoProvider P, we recommend the following setting:
              Read mode "H", request status "1", cache mode "1" or higher, delta cache "true" and SP grouping "1".
              Furthermore, the selection to use the structure element (KIDSEL) should be "true".
              The input-ready queries in "A" should not, and cannot, use a cache. The request status is irrelevant since queries in "A" are automatically set to current data. The delta buffer does not currently support hierarchy processing. Therefore, aggregation level "A" cannot completely support read mode "H". For input-ready queries at A:
              Read mode "X", request status "0", cache mode "0".
             The delta cache and SP grouping are not visible
Problems we have:
1) for query P/!!1P (PCA_AGQF/!!1PCA_AGQF in our example) does not allow changing the request status (greyed out). It now has value 0 instead of 1. It also does not allow to activate the delta cache flag. How to change this? In RSDIPROP we have set partitionmode to 1 for the multiprovider and activated the delta cache flag...
2) can we use the cache / delta cache principle for our planqueries? If so, how to ensure these settings remain activated in RSRT?

Dries

Hi,
To change the cache settings for your cube.
Open the cube in RSA1 and click in 'Chance'.
- click in the 'Environment' menu;
- expand 'InfoProvider Properties'
- select the option 'Change'.
You will be able to set the cache mode for this provider.
I don't think it will be possible use cache for a multiprovider, it is
not possible.

Very slow mailbox download times in Exchange cached mode

Hi,
I am running exchange 2007 on a 2008 server and have created a new server 2012 R2 x64 Remote Desktop server with Outlook 2013.
I am making use of the use cached mode feature. However it is taking a very long time to download all mail upon first setting up the mailbox in outlook.
seems to take 2min to download 500kb.
I have disabled all firewalls and AV scanners on the TS and Mail server.
networking between the two is excellent and download speeds and upload are very good.
Seems like exchange is slow at giving out the data or something?..... have tried on a local desktop and not the TS but still have the same problem.
any ideas?

Hi CHase,
shared mailboxes shouldnt be cached,only user mailboxes should.Reason for this is because it will download all info from shared mailbox and it can take some time.All company info will also be stored locally,so its security concern.
You mention that you turn on cached mode,is this under user mailbox or additional mailbox as shown below?
The one to left should be fine to cache all,but the one to the right only first check mark should be on.We have this configuratuon and senderandfrom registry works well.
If you access OWA,then choose to open another mailbox,then choose the "support center" mailbox,do you see all folders?
By granting full access doesnt give you send as permission,for this you will need to run this command:
Get-Mailbox "[email protected]" | Add-ADPermission -User "[email protected]" -ExtendedRights "Send As"

Shared Mailbox folders missing in Outlook Cached Mode

Since I got no responses to my
original post in section, "Exchange Server 2013 - Sharing and Collaboration: Site Mailboxes and Public Folders" I'll give it a try here...
We have Exchange 2013 Server (Version 15.0 - Build 913.22). I have a shared mailbox for our support team, "Support Center". This mailbox is configured as a "SharedMailbox". Our team members have been given Full Access
either by the Admin Web Interface or by "Add-MailboxPermission -User user1 -AccessRights FullAccess".
I am seeing this issue using Outlook 2013 Pro plus that manually created subfolders either in the root of the mailbox or folders under the Inbox are not visible. These folders are just for organization, like "Work Order Entered" and are not
like contact folders or any other special folders.
We determined if the Outlook client is configured for "Online Mode"/non-cached the folders appear and are accessible, but if your enabled Cached exchange mode the folders disappear and are no longer accessible. I have cahnged the cache slider
to go all the way right to say cache everything, not just the last so many days, but this did not resolve the issue either.
Upon further testing I have the same issue when I use Search-Mailbox with Targetmailbox and TargetFolder to my "Discovery Search Mailbox". The folders is created and logs are made, but the folder does not show unless I am in exchange online
mode and not cached.
HELP PLEASE! This is very annoying and we need cached mode for the registry key to place sent mail in "SenderAndFrom" sent items. It doesn't work in online mode.

Deleted documents in caching mode

Hey folks - Experts and general DM guru's, is there anyway to get
rid of a document completely in the caching mailbox? I've asked
this question a couple of time but haven't yet received an
answer.
Currently no matter how I delete a doc from the caching mailbox,
ie: Version from library, all versions of document from library,
delete from master library, the caching mailbox never gets rid of
it. If I do a search for the document it finds it again.
How in the world do you get rid of it?

tried manage library size but I don't see the document in there. I
might be missing it. Not the most friendly utility. a filter or
find option would help when there's over 1500 documents listed.
Scanned it three times though and don't see the doc in question.

Cache Mode 5 - BLOB/ Cluster Enhanced - Variables

Hello,
I have a very large query that I need to cache for performance.
I'm using cache mode 5 - BLOB/Cluster Enhanced.
I see that for variables in Char Restrictions area, it creates a new entry in RSRCACHE under my query under new Variables/Hierarchies section. But for variables in default values section it creates new selection entry in cache.
Therefore, I have moved all my variables (mandatory + optional) into default values section. Now when I run query with say single company code (which is single mandatory variable), it builds cache as required. Now when i rerun query for same company code and specific material type (optional variable) (which is actually subset of first cache that we just built), it actually doesn't hit the cache, instead creates new cache entry as selection under our query name.
Any ideas why subset of "Optional variables" are not hitting cache in my case? Any guidelines regarding how variables should be placed for cache query?
Thanks.
Abhijeet

I think I found my own answer. Here are the findings:
1. Subset of navigation will hit cache ONLY IF we are running for variables / fields that are in rows. In my case I was adding a value for variable which was in free chars and not in rows.
2. If I have built two cache objects - say for plants 1 - 1000 and plants 1001 - 2000...and then I run for plants 500 - 1500, then it won't utilize both cache objects...Instead it will create a new one. BI is not intelligent enough to consolidate two cache objects at this moment.

Cache Mode Settings Transport

Hello,
We are planning to implement the new BLOB/Cluster Enhanced Cache Mode setting. I plan to use the Query Mass Maintenance feature of RSRT to change the setting for all existing queries of an infoprovider. My question is will this action alone generate a transport? If so what objects are in the transport? Will the transport grab all the infoprovider queries?
Thanks,
TMS

Hello,
No. A transport will not be generated, all the necessary information it is as following:
As per note: 1026944 - New cache mode for BI 7.0 without directory.
Go to SE16 -> run report/table RSADMIN and verify if the data is in there.
u201CThat you can benefit from the new cache mode you have to activate it
for all your queries. Go to RSRT -> enter query -> properties ->
cache mode: 5 BLOB/Cluster Enhanced should be selected.
Or via mass maintenance (transaction RSRT -> menu "Environment" -> "Mass
Maintenance")u201D

Outlook non cached mode

Good day,
I have been tasked to see if there is a way to enable outlook to alternate between cached on non cached mode. This must be based on whether the user is logging onto his primary device for cached mode, and whether he is logging onto a temp device for
non-cached mode.
Can this be done using group policy? I know we can determine a primary device using SCCM, but not how to enable GPO to read from SCCM and then apply the correct setting.
Windows 7 SP1 x 32
SCCM 2012 SP1
Server 2008.
Any info on how this can be achieved?
Regards
VB Knowledge = 0%

Hi Carlo,
Before going further, to use group policy to manage Office, we need to download administrative templates files for Office from Microsoft download center.
>>This must be based on whether the user is logging onto his primary device for cached mode, and whether he is logging onto a temp device for non-cached mode.
For the Outlook setting we want is under User Configuration in GPO, we can create a new GPO, enable Loopback Merge processing mode in the GPO, configure the Outlook setting in the GPO, and then utilize Security
Filtering to just apply the GPO to the user’s primary device account.
Regarding Loopback processing, the following article can be referred to for more information.

Hi Ryan,
Iam trying to activate Delta Cache for some querys in RSRT.
We have many application servers,so, as you have advised i have choosen Mode 4.
And, ticked the check box delta cache.
Apart from that do i need to do any other settings?
Can you please aslo let me know what settings needs to be done for the below:
Read Mode
Persistence Mode
Optimization Mode
It'll be very helpful for me.

Cache mode query overview.

Hi guys,
In the Early Watch report I have an overview on how many queries use a certain cache mode (chapter 12.1), but it doesn't show which queries they are.
I have 4 queries with cache switched off and I'd like to know which ones they are. Any idea if there's a table/trx somewhere where I can find this information?
Thanks.
Eduard

hi Eduard,
yes, i added the info later just in case you want go by individual query, RSRT won't serve a mass checking.
please close the thread and reward helpful answer if RSRREPDIR serve your purpose.
hope this help.

Outlook 2007 cached mode receiving emails

we're rolling out a new build and ideally want all users to be in cached mode. The main issue right now is that users aren't receiving their emails as they come in, so if something urgent comes up, they have to wait for 30 mins (default outlook setting)
before outlook checks for emails again. Is there any way around it apart from changing the send/receive settings manually to something like 1 minute?
all windows updates have been installed on the PCs and we're using exchange 2010 SP3

Mass update for Cache Mode?

Hi all,
Is there a way to update ALL queries' cache mode? I know you can change the read mode for all queries by going into RSRT and typing "rall" in the t-code box while inside RSRT, but that is only for read mode. Is there a similar functionality for cache mode?

[GS70 Stealth Pro] RAID 0 Volatile Volume Cache Mode configuration

I discovered that in IRST there is an option to set a cache mode for my 3 ssd raid 0 array.
I've read the documentation by Intel and have some questions:
Are there any overall benefits/risks from enabling cache mode?
As I'm on a laptop, would write back be recommended? I read it increases chance of data loss on power interruption. What is the difference between how windows handles data integrity and the intel driver?
Read only mode seems to have the benefit of faster reads, does it have any downsides?
Thanks for your help guys!

Quote from: 3RAD1CAT0R;103729
I just recently acquired a GS70 Stealth Pro, which came with only 1 128gb msata ssd. i picked up two more, put them in, for a total of 3 128gb ssd's, and have since enabled raid 0. upon doing so (and restoring an image i took with acronis) my laptop will now boot directly to BIOS when UEFI boot is on. If i change it to Legacy, the laptop boots fine, first to intel rapid storage, then to the OS. r/w speeds are around 1k and 500, and everything says that the raid volume is enabled. is there an issue with being on legacy instead of UEFI? and what exactly is the difference?
It seems like your system is installed under Legacy mode which doesn't allow you to boot up under UEFI mode.
You'll need to re-install the system under UEFI mode to do so. I'd suggest to use the MSI BurnRecovery to create the Recovery disks and recover the system under UEFI mode.
People share that the most obvious difference between Win8 Legacy and Win8 UEFI is the boot up time, but I've never tried it on the GS70 model.
