High Update Response Time ticket from solman

Hi Experts,
We have monitoring setup from solman. We are getting an alert for ECC prod that the there is High Update Response Time. Can you please let me know how to fix it?
Thanks,
Asad

Hi Asad ,
How many update work process do you have . See a high amount of wait time for the update process
You may increase their number if you have enough memory .
Go to SM13 , Go to -> Administration of update system
Goto - > Statistics
Response Times: Rules of Thumb - CCMS Monitoring - SAP Library
Less than 1 second is the recommended , though sometimes you may breach it .
Thanks ,

High RFC response time in SAP BW system

Hello all,
How to analyze and fine tune high RFC response time in SAP BW system ?
Regards,
Archana

Hi
Kindly Check follows
1. Check the RFC connections are correctly Configured or not? You can execute the program “RSRFCTRC” and get a full log of the RFC connections details
2 you can check the BW queries are right optimized? Is this any network issues?
3. In which time are you facing the high rfc response? (During the 24 hours which time)?
4. Kindly refer the SCN & SAP Notes for overall system performance
Short Notes on PERFORMANCE MONITORING - ABAP Development - SCN Wiki
1063061 - Information about response time in STAD/ST03

High Avg Response time for logon requests via CMS

Hi Team ,
We are continuously receiving observing high Average reponse time for logon requests to the BO system via Central Management Server.
We observe response time up to 25043 ms .
Currently we are on SAP BO 4.0 SP7 patch 9 (4.0.7.9)
DB = SQL server 2008 R2
App Server = SAP NW 7.31 SP 7.
Also the size of our CMS DB is around 15 GB .
What could be the possible reasons ?
Regards ,
Abhinav

Hi Abhinav,
As one of the issues has been raised as a bug which is resolved in BI 4.1 so you can upgrade to resolve this bug. Also if the CMS database size is large then CMS has to search for objects through huge number of rows hence that will affect overall performance. So you can try to reduce this size as per my previous upate.
Apart this you can try following steps
Try to ping CMS DB server from BO servers and confirm the response is coming in 1 ms. Run tracert <DB servers name> from CMD and check the number of hops. If response time is not 1 ms or there are more number of hops then ask your network team to resolve network latency issue
You can increase the "System database connections" for each CMS from server properties. It is set to 14 by default which means the CMS will establish 14 connections to CMS database at any time. You can increase this value, however please make sure that the system database allows more connections than default 14 from DB side. This needs to be confirmed from your DBA.
Please add CMS cluster members in platformservices.properties file under Tomcat folder. Please refer following SAP KBA for steps to add the cluster members
       http://service.sap.com/sap/support/notes/1668515
       http://service.sap.com/sap/support/notes/1766935
   4. Also please confirm number of users simultaneously login to system at peak time. Usually one           CMS is capable of handling around 500 requests. So if you have more then 1000 users then add           another new CMS on same nodes if there is enough free memory on the server

High Dialog response time

Hi,
We have a solman 4.0 system. The average dialog response time of the system is very high. What can be done to bring down this response time??
Thanks in Advance
Amit.

Hi Amit,
Please check out the breakdown of dialog response time in Workload Monitor. Also, use the Time Profile to check if this high response time is at specific timings.

Service Profile Response time values from CRM

Hi experts,
I want to capture RESPONSE TIME from SERVICE PROFILE values defined in CRM system.If you refer CRMD_SERV_SLA transaction then you can find the defined values. In 0CRM_SRV_PROCESS_H Catalog, Code group, Code these values are appearing but I unable to find RESPONSE TIME value.
Has anybody tried capturing response time value in BW? or is there any other field shows this value in Data Source?
Regards,
Priyanka Joshi

Hi experts,
to get these values RESPONSE PROFILE value must be maintained in the Transaction but in our system its not available so I used SAP Exit to get the value and solved the problem.

Virtual Machine - high disk response time

Hi Everyone,
Got something strange happening in our lab at the moment and was wondering if anyone had experienced the same thing (and maybe has a solution).
Our lab environment in a nutshell:
2x Windows 2012 Hyper hosts cluster connected to a "home-made" SAN based on Windows 2012 iSCSI target.
Each Hyper-V host has two 1Gbps network cards to connect to the SAN via the Microsoft iSCSI initiator, with MPIO in load-balancing mode (least queue depth).
The SAN (Windows 2012 server with iSCSI target) has 4x 1Gbps cards, teamed two by two, so presenting two IP addresses used by each hosts to connect to it (via MPIO).
The disk subsystem on the Windows 2012 SAN is an external HP storage works with 25x HP 500 SATA disks, connected to the server via an INTEL RAID controller with 2x 240GB SSD caching enabled for read/write.
The iSCSI network is on a dedicated HP switch, with flow-control and jumbo frame enabled (tested ok).
Now the problem:
I've built a few virtual machines on the two hyper-v nodes and I'm getting very bad disk response time as soon as there is an increase in the disk traffic.
When the virtual server is doing very little, I get a normal 6-8ms, but I soon as I increase the traffic (by for example copying a big file, or installing an application), this figure shoots up to 200ms, 300ms and more!
So I first thought that it was my disk subsystem (and the SAN server), but while the spikes are happening within the virtual machine, the disks on the SAN Server are sitting at about 10ms, with some spikes to about 20ms (which is pretty good and what I would
expect to see within the VM because of the SSD cache).
I then thought it could be the network, but during those times of activity, the network does not get saturated at all. Barely 150Mbps to 200Mbps per link.
I even tried to disable MPIO and run everything across one Ethernet link, but still the same result.
Am I missing something here? doing something wrong? or is this expected behaviour?
Thank you,
Stephane

Hi,
VR38DETT is right, if you want to use more ISCSI bandwidth or redundancy you must use the MPIO method, Multipath I/O (MPIO) is a feature that provides support for using multiple
data paths to a storage device. Multipathing increases the availability of storage resources by providing path failover from a server or cluster to a storage subsystem.
More information:

High CPU response times, altough low CPU utilization

Hi Friends,
We have a performance problem after we migrate our basis system,
The current system is :
Database server : Sun SPARC Enterprise T5240 Server - 2 CPU's with 6 core, 8 thread, 1.2 Ghz
32 GB RAM
and we use another identical configured server as an application server.
Database is Oracle 10.2.0 and operating system is Solaris 10.
The problem is average CPU response time is 450 ms, and max. CPU load is %5 percent.
Pre-migration configuration with old servers, we had CPU response : 150 ms and max CPU load: 50%.
Has anyone of you, have experinced a similar problem with this new CPU's?
Thanks in advance

> I am aware that there might be lots of reasons, but what I guess is, there should be a parameter wrong with the CPU settings. This SPARC server CPU is a new tech. 6 core 8 thread one, which is expected to work much faster than the old simple dual core CPU.
Is it?
ABAP is basically a virtual machine and what is most important: ABAP runs single threaded. This means in consequence that the processing time of a program relies on the single processing power of one core. More cores means more parallelism but the speed of the single statement always relies on the power of one core and how fast it can get the data over the bus and back. So the significant number for speed is basically the Mhz (for ABAP, Java is very different).
Your old machine may have had a DualCore SPARC 1,2 Ghz and the new machine has one 1,4 Ghz 6core CPU (assuming so).
> However its response time is very high, although it is never utilized more than %5 percent.
see above.
> The problem might be at database settings(Oracle 10.2.0) or at Solaris ? ? ?
Well - no - I don't think so
Since ABAP is a single threaded application it can't leverage the CPU power due to the fact, that a parallelism in the program itself does not take place and hence the machine scales not linear with the number of cores. So you may have factually a machine with about 1 dot something CPUs and not 6 as you would expect.
This is not specific to SPARC CPU design but for all multi-core systems. A single threaded application is only as fast as the CPU speed. ABAP programs tend to be huge so you will also see effects of cache displacement and bus congestions. Less cores and more physical CPUs perform much better than any multicore CPU.
For Java the world is very different because Java works as one process (in the SAP case jlaunch) which has many many threads that can be executed in parallel on different pipelines on the CPU.
Unfortunately this is a design problem and there's not much you can do about it.

"Windows 8 using 100% of HDD with high average response times and low read/write speed"

Turns out this is a fairly well known windows 8.1 issue that has been plaguing users since at least 2013 and there is no one simple fix, so it may not be *entirely* hp's fault; but I've had two of these laptops, both the same model, the first one needing to be returned and exchanged for an entirely unrelated issue (hardware failure: ethernet port nonfunctional with lights stuck on). Both are refurbished. Both have been extreemly slow and unresponsive even compared to a lesser Brazos powered laptop I had before, but I've only recently decided to investigate why.
So if there is something HP specific going on here, I hope there is one simple fix. My average response time has gone up as far as well over a minute (>60,000ms), so I may be an outlier case here compared to the typical windows 8.1 hardrive responsiveness/bandwidth problem.
Edit: there is a case with another HP pavilion laptop (intel powered though, so it may be an intel storage driver issue described in the first link) being much, much worse.
This question was solved.

Guess what just now happened again
So using DISM did _not_ fix it.

Dialog response time exceeds threshold (SOLMAN Alert)

Dear All,
I found an alert in Solution Manager,
2.023 msec > 2.000 msec Dialog response time exceeds threshold (56 dialog steps)
What does this alert means?
Are SAP system still in a good performance?
And what kind of action i have to do to clear this alert..?
thanks and regards
Rio(nubie)

Hi
What does this alert means?
see answer Mapp Tyrone above
Are SAP system still in a good performance?
SAP performance is not determined only by response time. you have to look globally: your free memory, your ABAP dumps, your swap, your database statistics etc.
And what kind of action i have to do to clear this alert..?
No need to clear it. All you have to do is tune your SAP system to increase your current performance, and one indicator of that is the better response time.
hope it help you.

Any way to get more statistics and response-time info from cache processes?

I'm currently involved in an evaluation of Coherence for use as a global in-core cache/DB for data in the GB range. We'll try to run multiple cache process per cache in order to stay below 512MB heap-space per cache process.
In order to tune cache access times and understand the dynamic behaviour of the app we'd like to see some statistics info for cache access, e. g.
- requests processed per cache (process)
- requests answer time (per request, min, max, avg, median etc.)
- request answer size (number of cache entries returned, size of entries etc.)
- whatever else that helps ...
We are in position to get this kind of statistics info on the application side (when we call Coherence-APIs) but we'd need to see the statistics on a technical level per cache process.
We know about JMX/MBeans but that does not allow us to come up with log-files for statistical analysis and there is no way to correlate requests from the application to any statistics information (what request did cause what effect).
Any way to tell the cache processes to provide this kind of (logging) info (mesurements per request) and some summary.

David,
In addition to statistics that you can collect at the client tier (measuring the latency of individual cache calls), you could use a number of attributes exposed by the ServiceMBean.
If you look at a ServiceMBean for your partitioned cache service, the RequestAverageDuration and RequestMaxDuration attributes describe the latency of the underlying communication tier as seen from the client and does not include the serialization/deseriation cost.
The TaskAverageDuration, TaskMaxBacklog and ThreadAverageActiveCount expose the latency and expenses as seen by the server side, excluding the network tier expenses.
Also, there are number of statistics exposed by the CacheMBean related to the underlying backing map efficiency such as AverageGetMillis, AverageHitMillis, AverageMissMillis and AveragePutMillis.
You can also create your own subclasses for backing map implementation and implement custom MBeans that would expose any addition information you wish to collect.

Gene

Performance Issue - Update response time

Hi,
I am trying to get the equipment data and I have to link with asset. The only way I could find is through m_equia view. I select the equipment number from m_equia passing the key as asset no and from there i go to equi and get the other data.
But when i am trying to select from m_equia the database time is more. So, can some one suggest me a better option for this other than the m_equia to get the equipment details with asset as the key. I also have cost center details with me.
Thanks,

Hi,
Please find the select on m_equia and further select on it.
Get asset related data from the view
IF NOT i_asset[] IS INITIAL.
   SELECT anlnr
          equnr
     FROM m_equia
     INTO TABLE i_asst_equi
     FOR ALL ENTRIES IN i_asset
     WHERE anlnr = i_asset-anln1 AND
           anlun = i_asset-anln2 AND
           bukrs = i_asset-bukrs.
   IF sy-subrc = 0.
     SORT i_asst_equi BY equnr.
   ENDIF.
ENDIF.
Get Equipment related data
IF NOT i_asst_equi[] IS INITIAL.
   SELECT equi~equnr

HOW to update real time data from sap to other application?

We have two option of passing data from sap to other system.
1. web service
2. through idoc.
can anyone tell me advantages & disadv. of these two options.
Which scenario shd we use web service & idoc.
How is idoc triggerred.?
Is it only through user exit?
Kindly suggest any other ways for interacting with a 3rd party system which does not use a file.

Dear Libin,
IF you are using sap sytem as a sender then its better to use idoc's. Actually both systems (idoc and webservice) have there own advantages and disadvantages. Look up sdn for more info.
My personal choice would be idoc since with webservices you would need special tools like xml spy or altova and the skill to analyze and run those tools.,, its a little tedious..

Higher response time after adding more CPU

Hello all,
have you ever experienced that after incresing SAPs (adding 2 more CPU + 4 GB of memory) on the VMware ESX 3.5 the DB response time went from 150 to 400-500 ms ? NO DB parameter were changed. In app server, only extended memory and program buffer were enlarged.
We are running ECC6 system on MAXDB 7.6.6.3 (SLES9). MAXCPU is set to 1
Any idea ?
Thank you.
Pavol

> We are running ECC6 system on MAXDB 7.6.6.3 (SLES9). MAXCPU is set to 1
I'd always set MAXCPU to the number of physical CPUs/cores you have. It's VERY unlikely that the database will use more CPU than the application.
The database can't scale, if one CPU is used other requests have to wait.
