Opening Bex analyser on Excel takes long time on some client

Hi,
We have installed BEx analyser on several PC client, on my PC BEx is opening in 2 or 3 seconds, on others it can takes 30 or 40 seconds.
We have checked the configuration and the problem is the same on two PC having same parameters.
Has anyone seen this problem and solved it ???
Thank you for your help !

Hi,
The OS installed for everyone is XP SP2 and we are using sap logon 710 Final Release, 7100.1.3.1029 version.
Every user works on a pc with 512 Mo RAM and 2,8 Ghertz.
We try to maintain the same configuration for everyone that why I don't understand this difference when opening Bex Analyser .
Thank you for your help.

BEx query selection screen takes long time to popup

Hi,
I have a query which is taking long time to popup the selection screen. I have tried in RSRT the generate report option, the generating report takes 45 to 60 mins. After the report is generated the query selection screen comes up in couple of seconds. The first time I run the query everything its fine but then for the second time the problem comes back again.
The selection screen takes +/- 40 mins to comes up in RSRT and in the portal it times out.
I have run the statistics of the query and according to the statistics report the query takes a lot of time for the following component :
OLAP: Query Gen. 2681,312682
I have removed the query from the cache monitor and after that regenerate the report. But these steps didnu2019t solve my problem.
I made two test queries, in one query I have made the CKFu2019s and RKFu2019s directly at the infoprovider, and dragged and dropped in the KF structure. In the other query I made the CKFu2019s and RKFu2019s in the query KF structure itself. The query where I have the CKFu2019s and RKFu2019s at the infoprovider that query times out, the other query where I put the CKFu2019s and RKFu2019s in the query KF structure doesn't has this performance problem.
What I donu2019t know is why the query is failing when I use RKFu2019s and CKFu2019s from the infoprovider, the other query donu2019t have this problem.
Please advise how to proceed.
Thanks in advance,

BeX Analyzer Variable screen takes long time

Hello,
Recently migrated 3.5 workbooks/queries to 7x.
When clicking on 'Change Variable values' button, the variable pop up screen takes about 10 seconds to appear for some users.
It takes somewhere between 30-40 seconds for some users...
All users are in same patch level. In 3x all users were experiencing same time delays.
But from 7x it has got worse. Now we are on 730 release, Patch 7.
Searched forums and SAP Notes. Didnt get any good solutions.
Some said clearing %tmp% files helps. It works for 1 or 2 users only. Its not the solution.
Any other solutions please?
Thanks

The problem is not associated with the selection/results.
Problem is the time it takes to bring up the variable screen itself.
Thanks

Database Connectivity takes long time if one of the Node is down .. ??

Hello All,
Env: 10.2.0.4 on Solaris 10
I have 2 nodes.
When Node1 server is down, it takes long time to connec to the database.
tnsping would give "OK(2050ms)". Below is the tnsalias.
RAC_test =
(DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST=20.268.169.123)(PORT= 1521))
     (ADDRESS = (PROTOCOL = TCP)(HOST=20.268.169.127)(PORT= 1521))
     (LOAD_BALANCE = yes)
          (CONNECT_DATA =
        (SERVICE_NAME = DK.com)
      (FAILOVER_MODE =
        (TYPE = SELECT)
        (METHOD = BASIC)
        (RETRIES = 180)
        (DELAY = 5)
)I put the trace on sqlnet.ora and found that first it pings to the "20.268.169.123",
since the Server is down there will not be any reply and this consumes the delay and
later it would ping "20.268.169.127" and connect to it.
If i keep "20.268.169.127" above "20.268.169.123" in tnsalias, and keep "LOAD_BALANCE=no",
it gets connected very fast, as its directly connecting to Node2. In tnsping i get Ok(40ms).
How do i reduce the connect timing if i use the first step. Why does it take long time for
Oracle Client to understand that the Node1 Server is down ?
TIA,
J J

I hope the IP's you are using in the TNS are Virtual IP's.
You must use Virtual IP's / hostnames for the failover to be quick. If Node 1 is not available then then it's (Node 1's) virtual IP would also get assigned to Node 2 hence all client connections are still able to get a response from the Node Virtual IP address without needing to wait for TCP/IP timeouts. This helps clients to get notified immediately that node 1 is unavailable and the connection tries the 2nd ip/host in the connect descriptor.
Hope this helps.

Hi Chetans,
I have had the same problem, and I had to create a OSS message to SAP in order to solve this issue, until now I don't have an answer. They made me to change a lot of configuration in Java and BW without luck. To tell you more, when we try to export to excel the java instance restarts aumotatically.
But we have this problem, when we try to export a huge quantity of data, so I found a note which says the limitation of exporting to excel. Take a special attention to the Performance section.
Note 1178857
[https://service.sap.com/sap/support/notes/1178857|https://service.sap.com/sap/support/notes/1178857]
I recomend you that you create a message to SAP. If you find a solution, please let me know.

Payables Account Analysis report takes long time to produce xml output

Hi,
I am trying to get xml data for the Payables Account Analysis report. I have changed the output format of the concurrent program to XML.
The report takes long time to produce the xml data irrespective of the number of rows fetched. But the same report with Text output runs very fast.
Any reason why the xml output takes long time?
thanks in advance

Hi,
Thanks for the reply.
As mentioned above, i deleted the Q_FLEXDATA and ran the report. it takes less time.
But Will the report data not affected when we delete Q_FLEXDATA Group? and Why this flexdata group affects the running time?

One Form 10g takes long time to open

We have created one form using Object Library and all objects are inherited.
It takes long time to open as compared to other forms which are inherited from Object Library.
Anybody having any idea. It would be great if somebody can provide some help

This form contains 3 tabs and one tab is completely inherited from Object Library (the whole block, items etc). I have tried to remove this inherited tab then it works better. So i think its definitely something to do with object library.
Thanks alot.

My mac shutdown suddenly fr0m time to other and take long time to open

hi everybody,
I think i have big problem ,i have macbookpro I5 13" early 2011 , i just changed the board to I7 ( used board got it from net ) after USB ports in my original logicboard are damaged due to drop , after changing the board the mac is unstable, it take long time(half hour!) to show up anything after press power, yes I press power and there are no response from the mac (black monitor as its ) , just i hear a noise from the empty CD drive . once it open it work fine for a while (may 2 hours or more ) and then shutdown suddenly! and you have wait more than half hour to open it again if im lucky.
Itried to rest the mac many times, replace the RAM places , i thought may the problem come from overheating the CPU, i monitored the CPU tempreture just before the suddenly shutdown was 57C
please help ,any suggetions ?

App-V 5 Full Infrastructure Apps take long time to stream to the client

Hi was wondering if anyone has the same issue as i am or knows a fix for this, below is my problem and the troubleshooting i have done.
Overview of problem
App-V 5 apps delivered via App-V 5 full infrastructure take a long time to stream to the client and this means the user has to wait if they try and run an application before it has streamed to the client. Users sometimes have to
wait 2 or 3 minutes for an application to stream and this is about 40 times slower than basic SMB and HTTP transfer tests show the system is capable of (see performance results below).
App-V 4.6 apps delivered via App-V 4.6 full infrastructure and HTTP streaming are fine.
Overview of environment
App-V 5.0 SP1 Full Infrastructure.
App-V servers are running Server 2012 on Hyper-V 3 or ESX 5.1 with 2 x vCPU and 4GB RAM.
SQL servers are a SQL 2012 cluster.
Separate servers for SQL, management, publishing, content and reporting.
Management, Publishing and Content servers have two servers per role and NLB to provide load balancing. So 7 servers (2 x Man, 2 x Pub, 2 x Content, 1 x Reporting)
Two further sites with 2 x Pub and 2 x Content each. All publishing servers pointed at the load balance address for management.
Content delivered via HTTP
Clients are physical desktops and laptops running Windows 7 SP1 x86 and Windows 8 x86
App-V client is 5.0SP1
Clients are pointed at their nearest publishing server NLB via a script which looks up the client IP address and uses PowerShell to configure the publishing server
Content is streamed from the nearest content server NLB by setting the PackageSourceRoot to the nearest content NLB (via the same PowerShell script above).
App-V apps delivered per-user via AD group. One AD group per application. Approximately 200 App-V apps published so far - will eventually reach 400 as we sequence more. About 9000 users.
Analysis performed so far
Servers not heavily loaded. CPU averages 5%. Lots of RAM free. Very low disk IO. Problem also occurs out-of-hours so we are 99.9% certain that server resources are not a cause.
Streaming performance is the same from all 6 content servers and all 3 NLB addresses (tested by changing the value of PackageSourceRoot). Wireshark used to confirm packages are really streaming from the correct location, enforcing
our belief that the problem isn't at the server end (unless all 6 servers are affected).
Streaming via both HTTP and SMB2.1 is approximately the same (tested by changing the value of PackageSourceRoot between http://xxxx and \\server\AppVContent).
Wireshark used to confirm we really are using the protocol we think we are using.
All clients exhibit the same behaviour. Issue reported by many users. 5 test PCs chosen at random at all 3 sites confirmed to have the slow streaming problem.
Slow streaming from both Hyper-V and VMware ESX servers.
Client not heavily loaded.
Affects all App-V apps although it obviously affects the larger ones more.
All App-V apps have a Feature Block 1 setup.
If we copy the ".appv" file from the server to the client via either HTTP or SMB then it's reasonably quick (up to 480Mb/s). So we don't believe the network or servers are at fault. For example:
We can copy a 149MB .appv file via SMB from the content server to the client in 5 seconds.
We copy HTTP download the .appv file from the content server using IE on the client in 5 seconds.
But if you ask the App-V 5 client to fully download the sequence then it takes 2 - 3 minutes.
The App-V 4.6 client takes about 8 - 10 seconds to fully download a similar sized application.
App-V 5 publishing works fine - when a new user logs on they get their list of application straight away, it's just the streaming which is slow.
Once the App-V app has streamed locally it runs fine and with a decent performance.
Looking at a Wireshark trace of the streaming you can see that the slow performance is due to the transfer stopping and starting a lot. You only notice this when you zoom into the performance graph a fair bit.
Each time the HTTP server stops sending traffic, it doesn't start again until the client sends a "TCP Window update". Each "stop" is of a different length, but just taking a few from the middle I get 0.06s, 0.11s,
0.13s wasted etc.
I can see that it's the client stopping the transfer by reducing its advertised TCP Window Size. I'll provide an example:
Server sends 9 x 1514 bytes. Client responds with an ACK and a Window size of 54016 bytes (256x211)
Server sends 11 x 1514 bytes. Client responds with an ACK and a Window size of 37888 bytes (256x148)
Server sends 10 x 1514 bytes. Client responds with an ACK and a Window size of 23296 bytes (256x91)
Server sends 15 x 1514 bytes. Client responds with an ACK and a Window size of 1280 bytes (5 x 256)
Server stops sending (I'm guessing because the client advertised Window size was less than a single packet's worth of bytes)
<0.1 seconds passes>
Client sends a "TCP Window Update" re-advertising a TCP window size of 65536 (256x256).
Server starts transmitting again
So the way I see this is that the App-V 5 client is controlling the transfer speed by utilising TCP Window flow control. The trace was taken at the client end so there's no room for anything on the network to be fiddling with flow
control (and we've confirmed there are no traffic shapers in the loop).
We've also tried streaming directly from the local client by copying some App-V 5 apps down to the client, creating a SMB share on the client and changing PackageSourceRoot to \\localhost\AppVContent (i.e. so we are streaming directly
from the client to the client - to remove the network from the equation) and there is only an improvement of 5 to 10 seconds. So we know it's nothing to do with the network or the servers.
We've tried turning off TCP auto-tuning on the client with:
netsh interface tcp set global autotuninglevel=disabled
and turning off TCP chimney offloading (which is off anyway because the NIC doesn't support it and Netstat -t output shows "InHost" for offload state for all connections) with:
netsh int tcp set global chimney=disabled
and nothing has improved.
So we've now focussed on the extraction of the .appv (ZIP) file on the client.
Using Windows Explorer it takes 75 seconds to extract the ZIP file
Using 7ZIP it takes 9 seconds to extract the ZIP file
Yeah we've always known that the Explorer ZIP engine is terrible. That's why we use 7ZIP or WinRAR on our clients.
So we've started to wonder if the problem with the slow App-V 5 streaming is because the client is downloading the .appv file and extracting it as it goes along in a single thread. If the App-V 5 client is using the same terrible
ZIP engine that Explorer does then that would explain the slow performance. The "download" appears to take a long time because the client is using TCP flow control to slow the transfer since it's extracting the .appv file using a very slow ZIP engine
and it's all in a single thread.

Guys,
Just wanted to give you a brief update basically close this thread as Answered.
We had submitted 4 App-V 5 Bugs to Microsoft and these were reproducible and an explanation was given on work around to them. Microsoft
sent down a App-v developer to have a look at our problems. They said they will try and include the Bug fixes in SP2 which should be out in a few weeks or they will definitely be included in SP3.
In regards to the slow streaming it all came down to the Disk IO.
We found that you could simply enable "Turn off
Windows write-cache buffer flushing on the device", then start streaming the app and then disable "Turn
off Windows write-cache buffer flushing on the device" immediately after
(we don't want to leave it on) and that basically fixed the issue.
But a normal user would not have permissions to do
this, so a code was written to enable and disable this option.
Apology for not going in detail, like my opening thread, its very late.
but if you would like a detailed analysis please message me.
I would like to Thank the Talented Consultant who designed and implemented are App-V infrastructure who found the bugs and created all
the work around and who also emailed the detailed analysis of the problems to Microsoft that got them interested.
Simon Bond from Ultima Business Solutions.
Thank you

10.4.8 Client takes long time to get to login window when bound to OD.

I am working on a system in a school. We have a dual processor g5 xserve with 4 gb of ram, the raid card, and 3 500 gb drives.
Fresh install of 10.4.8 with all the updates.
Raid 5 split in 2 volumes, one for server and one for data.
AFP service running.
Local dns running.
Promoted to open directory master.
This is the following test scenario i have.
there is a user called studenttest and he belongs to a group called cccarstarmembers and is in a workgroup called student.
the studenttest users home folder exists in a sharepoint called students that is set up on the data partition.
there is a sharepoint called cccarstar that holds data for some educational software we use. The owner is administrator with rw access, the group is cccarstarmembers with rw access and others have no access.
The student workgroup only has a few changes like dock location just for testing purposes to verify that the work group is working properly.
When i bind a newly built 10.4.8 client with all the updates to the od server it intermittantly takes a long time for the client to get to the login window when it is powered up. Sometimes it will get to the login window in 45 seconds and other times it will take 5 minutes. This is not consistant. if you unbind the client then the computer will behave properly consistantly.
I have tried binding the client to the od master using the fully qualified domain name and the ip address with the same results.
the search path on the server is "dc=osx1,dc=erm,dc=sd,dc=bc,dc=ca" and on the client it auto populates at cn=config,dc=osx1,dc=erm,dc=sd,dc=bc,dc=ca".
I have changed the search path on the client to match the search path on the server with no success as this is what used to work for us on panther setups.
But this school has a panther client i am working on at the same time with the same applications installed and system preference settings and when i bind it to the same od master with the same search path that is displayed on the server it works fine. all users work, all groups and work groups work.
Dns appears to be working. lookup provides the correct forward and reverse lookup info on the server, if i use either the panther or tiger client and use lookup with the servers fully qualified domain name and ip address i get the correct answers back.
I had this problem before where tiger gave me slow to login screen problems but panther wouldnt when bound, and apple told me that it was because i had afp guest access disabled on the server. Enabling it resolved the issue about 6 months ago at another site but this time when building the server i made sure it was on from the start even thoug it is off by default.
Any suggestions, i am pulling my hair out and about 8 working hours from a deadline.

I've seen this a lot.
This Knowledge Base article refers to Active Directory but we've seen this fix login delays with OD-only environments too:
http://docs.info.apple.com/article.html?artnum=303841
Another one of the causes is when you have multiple network mounts and your AFP service has guest access disabled. The loginwindow is trying to authenticate to each share with the username given and it is failing when that user account is not authorised for that share.
Another can be the LDAP timeout value(s). Try adjusting these in the LDAPv3 plug-in.
Also make sure your network ports have portfast/faststart set on the Mac ports. Sometimes because of STP the port isn't initialised fast enough for the OS when it's ready to start LDAP'ing.
Let me know if any of this helps.

BPM Process chain takes long time to process

We have BI7, Netweaver 2004s on Oracle and SUN Solaris
There is a process chain (BPM) which pulls data from the CRM system into BW. The scheduled time to run this chain is 0034 hrs. This chain should ideally complete before / around 0830 Hrs. <b>Now the problem is that every alternate day this chain behaves normally and gets completed well before 0830 hrs but every alternate day this chain fails</b> there are almost 40 chains running daily. Some are event triggered (dependent with each other) or some run in parallel. In this, (BPM) process chain, usually there are 5 requests with 3 Delta and 2 full uploads (Master Data). The delta uploads finishes in 30 minutes without any issues with very few record transfers. The first full upload is from 0034 hrs to approximately 0130 hrs and the 2nd upload is from 0130 hrs to 0230 hrs. Now if the 1st upload gets delayed then the people who are initiating these chains, stop the 2nd full upload and continue it after all the process chains are completed. Now this entire BPM process chain sometimes takes 17 -18 hrs to complete!!!!!
No other loads in CRM or BW when these process chains are running
CRM has background jobs to push IDOCS to BW which run every 2 minutes which runs successfully
Yesterday this chain got completed successfully (well within stipulated time) with over 33,00,000 records transferred but sometimes it has failed to transfer even 12,00,000 records!!
Attaching a zip file, please refer the 21 to 26 Analysis screen shot.doc from the zip file
Within the zip file, attaching Normal timings of daily process chains.xls the name explains it.
Also within the zip file refer BPM Infoprovider and data source screen shot.doc please refer this file as the infopackage (page 2) which was used in the process chain is not displayed later on in page number 6 BUT CHAIN GOT SUCESSFULLY COMPLETED
We have analyzed:--
1)     The PSA data for BPM process chain for past few days
2)     The info providers for BPM process chain for past few days
3)     The ODS entries for BPM process chain for past few days
4)     The point of failure of BPM process chain for past few days
5)     The overall performance of all the process chains for past few days
6)     The number of requests in BW for this process chain
7)     The load on CRM system for past few days when this process chain ran on BW system
As per our analysis, there are couple of things which can be fixed in the BW system:--
1)     The partner agreement (transaction WE20) defined for the partner LS/BP3CLNT475 mentions both message types RSSEND and RSINFO: -- collect IDOCs and pack size = 1 Since the pack size = 1 will generate 1 TRFC call per IDOC, it should be changed to 10 so that less number of TRFCs will be generated thus less overhead for the BW server resulting in the increase in performance
2)     In the definition of destination for the concerned RFC in BW (SM59), the Technical Setting tab says the Load balancing option = No. We are planning to make it Yes
But we believe that though these changes will bring some increase in performance, this is not the root cause of the abnormal behavior of this chain as this chain runs successfully on every alternate day with approximately the same amount of load in it.
I was not able to attach the many screen shots or the info which I had gathered during my analysis. Please advice how do I attach these files

Hi,
Normally index creation or deletion can take long time in case your database statistics are not updated properly, so can check stat after your data loading is completed and index generation is done, Do creation of database statistics.
Then try to recheck ...

SSRS 2012. ReportServer takes long time to be up.

SSRS 2012 Sp1
Hi guys,
I am using SSRS as my reporting platform, but I have always got the following issue.
SSRS ReportServer takes time to load.
The first time takes long, then less time but only if the ReprotServer web page is continuosly retrived.
HERE the problem:
If the ReprotServer page is not used after a short time (let me say 10 min), the page takes long time to be up again.
I have checked the configuration that is set as for default 12 hours.
Is there a way to speed up the ReportServer opening page time?
Thanks for your help

Hi Fasttrack2,
According to your description, you want to optimize the performance of your report. Right?
In this scenario, when your report page is not active for a short time, it will take long time to render again. This is because the you have the report timeout. You can select "Do not timeout report" in Processing. Please refer to the link below:
SQL Server Reporting Services – Timeout Settings
For the performance issue, it can be many reason cause the report running slowly. Please refer to the articles below to optimize the report:
More tips to improve performance of SSRS reports.

If you have any question, please feel free to ask.

Takes long time for shutdown after adding to domain

Hi,
Workstation OS - Window 7
Domain Controller OS - Window server 2008 R2 standard
Following thing i have measure with Stopwatch.
1) When the laptop is in workgroup, it takes just 17 second for shutdown.
2) when i added the same laptop in domain ( corp.abc.com ), now it takes 1minutes and 22 second for shutdown. ( it just show shutting down screen )
Why the shutdown time increased so much?
Do you have any idea?
Note:- i have not make any changes in laptop, nor added any software. I have done the above testing because user start complaining that after putting laptop in domain it takes long time for shutdown. It's happening to all laptop where the OS is window 7
There is no logoff scripts / gpo's as well as we don't have roaming profiles.
Please advice.
Thanks & Regards,
