Wait Time in ST03

Hello group
We've been looking at Wait times (i.e. the time for the Dispatcher to find a free WP). Although we have plenty of DIA processes, the Wait time seems to increase steadily.
Just after IPL/SAPstart, the wait times are at less than 10ms, but growing to upto 120ms by end of the week.
SAP are on the case, but I wanted to ask the group whether anyone has experimented with giving the Dispatcher (disp+work) process even a higher priority (10 instead of 12) or even run it in a separate mem pool ?
Regards
Jo

Hi Jo,
Which kernel level you are and at what patch level.
I hope you've already searched for standard notes for this.
Are you really getting performance issues in the system? if not then it might be a good indication of the kernel problem of wrongly showing the statistics data.
Few notes you can refer 1029617, 1014072.

  • High GUI time in ST03

    I found high GUI time in ST03.
    Example: In last minute's load --> workload overview -->
    Start of interval  27.10.2008  07:43:00
    End of interval    27.10.2008  07:58:00
    Time period        0   Day(s)  00:15:01
    I found 1280ms Roll wait time and 1280 GUI time. It seems too high. How can I find what cause it? how can I locate the root case?
    Please advise. Thanks so much.
    James

    Hi,
    Here are the few things to check when the GUI time is high.
    1. Check in ST03--> Transaction Profile the Tx SESSION_MANAGER may be on top id yes, the load caused by the transaction SESSION_MANAGER, combined with the high roll in + wait time could indicate that the SAP Easy Access menu might not be configured correctly and should be tuned to improve overall response times. It is also possible that your users have been assigned disproportionately large user menus. We advise you to ensure there are a reasonable number of entries (nodes) in the User Menu.
    Generally, its recommended that users should have no more than 1000 and as an absolute maximum 2000 menu nodes configured, (for comparison, the complete SAP menu contains 70,000 entries).  A high number of entries may lead to high memory consumption on the server and to long response times for the menu. Refer to SAP Notes 203617 and 203994 for details
    2. ST06 --> Detail Analysis Menu --> Lan check by Ping with more than 10 Presentation
    servers.
    See the Average and Loss coloumn and check wether is there any problem exits.
    However, review the following recommendations to identify any network issues. Given below are the response times which are thresholds for a good network performance.
    Recommendation: Characteristic response times are:
    -  In a local area network (LAN) : <20 milliseconds
    -  In a "fast" Wide Area Network (WAN) (for example, 256 or 384 KBit/sec):   < 50 milliseconds
    -  In a "slow" wide area network (WAN) (For example, 128 KBit/sec or less): < 250 milliseconds
    -  Losses of data packets ("Loss") should not occur at all.
    Review SAP Notes 203924 (under subheading 'General Performance Analysisu2019), 8963 and 578118 for further information on SAP GUI and response time components.
    In case of long response times due to performance problems in the network (in particular when using SAPGUI in WAN), you should use configuration "Low Speed Connection" in SAPLOGON. As a result, menus are only transferred on request, and the quantity of the transferred data is reduced correspondingly. This measure reduces the network load significantly. You can find this setting option under: SAPLOGON -> PROPERTIES -> ADVANCED.
    Option for a low speed connection:
    On a low speed connection (LSC) to the network, the benefits of the improved interaction design may be outweighed by increased response times due to the heavier network traffic. To counterbalance this effect, SAP has introduced the option for a low speed connection to the network in Release 4.6. A flag can be set in the options of an SAP logon connection item or on the SAP GUI command line. This action has the following effects:
    -  Menus are loaded only on demand as before
    -  Background Bitmaps are not transferred (depending on the application)
    -  The list control transfers only the lines that are visible on the screen
    -  The application can query the flag to react to the network condition individually.
    Examine the following SAP Notes and verify that the SAP recommendations contained are fully implemented:
    -  SAP Note Number 161053   Low Speed Connection is in use
    -  SAP Note Number 164102   Network load between application servers +camera front end
    -  SAP Note Number   62418   Network Load of SAPGUI Frontend Communication (Required Bandwidth).
    Please let me know if the performance improves.
    Thank you,
    Tilak

  • High roll wait time

    For my below crm transaction for a perticular user the response time is ~18000 ms out of which 15130 is roll time. Memory used is 16 MB.

    I checked another similar instance again today with high wait time.  Most of the time was wait time. There were NO RFC RECORD. just http record with most of it being on the server (Remote exec. time ~ 16 534 ms).
    Now i assume calling time = gate way time + remote exec time. So as most of it was on the server I can rule out network.
    I checked st03 and rfc times were really small. Also we have plenty of wps .. ~ 90. So not sure why still the high wait time. Also stad does not give any RFC record. If this was rfc will it now show up ?

  • Network/roll wait time is high

    Hi,
    One of my dialog instance is showing high response time at SMLG.
    When i am checking Dialog Overview at RZ20, network response time of this server is very high.
    When i am checking the parts of response time at ST03, roll wait time is always around 70% for this instance.
    (4.7,2003 server, SQL 2000)
    Kindly suggest me to resolve this.
    Regards,
    Gayathry.

    Hai,
    Roll wait time means: During processing of some dialog steps, the user context may be rolled out; for example, during RFCs when the client is waiting for a response from the server. This wait time until the dialog step can continue is called the roll wait time.
    try to check what RFC causes this, somtimes this may lead to rollfile overflow and in turn some background jobs might fail due to rollfile overflow.
    Check SAP Notes:1100926 and 578118.

  • Roll wait time very high.

    Hi All,
    We are facing a strange problem.
    Our system is performing low just because of the share of high Roll Wait Time.
    Can anyone tell why it is so high ? and how to reduce it's time.
    Now it's taking more than 60% of Total Resp. Time.
    Thanks & Regards,
    Santosh Rajput

    Hi Santosh,
    sometimes we have the same problem when inserting records with MM41. In ST03 Top Response Times the roll wait time takes nearly  minutes, the whole response time 5 minutes.
    The SAP HELP defines roll wait time as follows:
    Wait time in the roll area.
    If synchronous RFCs are called, the work process performs a roll out and waits for the end of the RFC in the roll area. The RFC server programs can wait for other RFCs to be sent to them in the roll area.
    I'm not quite sure whether this explanation meets your or my problem because the problem occurs just two or three times a day. So - what is the process waiting for?
    Can anybody help?
    Thanks and best regards,
    Frank Ihnen

  • The wait time and resolve time is DEPLORABLE

    Today is the third day in a row I have called into Verizon for the same issue. Day one spent 25 minutes on hold and NEVER got to speak to a person before I hung up. Day 2 Had a 15 minute hold before I spoke with someone, who then told me I had to speak to directv about something that was related to the Verizon part of my service, called directv confirmed it was a Verizon thing with a supervisor. Called BACK into Verizon waited for 30 minutes before I spoke with someone, got 30 seconds worth of talk in before another 15 minute hold, he came back on no apology not anything about the absolute rudeness and lack of courtesy. He told me they would have it fixed by the end of the day. Now here it is the nest day still not resolved, So I write this (while on hold waiting to have the call answered, its been 20 minutes) She finally did answer and was down right rude and through me right back on hold. I am so fed up with big business...

  • How to keep waiting time between processed messages !!

    Hi Folks,
    I have got one scenario required waiting time between processed messages. The problem as follows !!
    File --> Proxy scenario. I receive 15 messages from sender side (same messages structure) so working with one interfaces. File picking and transforming this message and split into 2 messages. messages are receiving to receiver. I am using BPM with 7,8 steps like receiving step, block , message transformation step , internal block 1 for sender 1, internal block 2 for sender 2.
    All things are working fine, messages are going to receiver properly. But customer requirement is , wait step required between processed messages before sender1. I have put wait step still, PI picks all messages in one shot processing and waiting for 2 minutes, after 2 minutes sending all messages at the same time, this process is not working.
    I have tried with wait step in mapping (Sarvesh) given excellent idea, still PI works the same way.
    Can someone please explain a bit why the messages or not waiting message by message. I am using EOIO with Queue name and file process mode "BY NAME" and I have tried "BY TIME" as well. I have given priority to this Queue. On BPM Queue assignment : One Queue.
    Please I am expecting positive answer !!
    Many Thanks in Advance
    San

    Hi Rudolf Yaskorski ,
    Not sure about your PI release and BPM model, do you create separate process instance for each file, or do you process files collecting them in one single instance? Are you using parallelization within your ccBPM ?
    I am using serialization, I don't think bpm can do Parallization until PI 7.0, but PI 7.11 has got has queue assignment. But I am using one queue. This must be serialization.
    To me it looks like your issue is not in ccBPM but rather more in polling files (as per your post file CC polls all 15 files in one shot). So if you wish to poll the files not at the same time some workaround is required. Possible options you could check out:
    A. Either implement "wait" in your mapping based on file name or other criteria (e.g. directory name). Check out if respective BPM instances are really created at different times.
    I have used wait step in mapping. These 15 messages has to go through one interface. So I am using one interface. But I have checked mapping process time in all messages on receiver system. Shows same timing, even though I put 40000 ms waiting time in mapping.
    B. Try polling different files (or use different directories) with different channels and coordinate starting / stopping of your channels by scheduling availability for each CC in RWB. E.g. you poll file 1 with CC 1. You start 2 minutes later CC 2 and poll file 2. And so on.
    I am not clear about this . On BPM waiting step is working and it keeps wait all messages, which are coming through one interface. Then it releases all messages at the same time.
    I don't know how to resolve this. I have tried with Transport acknowledgment, but all messages are going to reciver system waiting at receiver system in priority queue and processing in EOIO, but taking so long. Rather all messages go and sits in queue, I want to stop messages by message with 2 minutes time gap. How please?
    Kind Regards

  • Waiting time between entry posting in R/3 and avail. in BW

    Dear SAP community,
    We have set up a process chain which gives us the freedom to load GL account into BW on an ad-hoc basis.
    Unfortunately it is not really ad-hoc after we have  posted an entry in GL account in R/3 we need to wait approximately 1 hour before we run process chain in order to see posted entry. If we run process chain immediatly after posting entry we woul not see the entry in BW.
    Does anyone knows if there is a waiting time from when we post an entry into SAP R3 to when we can run the process chain and see the posting in BW?
    Thanks  a lot for you help.
    Stefanie

    Hi Stefanie,
    What is the Datasource being used?
    For old GL extractors, like 0FI_GL_4, there is a safety interval upper limit of 1 day, meaning data posted till yesterday will be extracted if the chains run today. There are workarouds given by SAP to extract most recent data for these.
    For new GL extractors like 0FI_GL_10, there is a safety interval lower limit of 1 hour, meaning the most current data would be extracted and there would be an overlap of 1 hour between delta loads and some records are extracted twice.

  • How to increase the waiting time for response in Adapter Engine not in IE

    Hi Experts,
                It is a SOAP to Proxy Synchronous interface. SOAP system is sending the request to PI, PI sending the same request to ECC system, After execution of some logic response back to PI in 7 minutes. In ABAP Stack(sxmb_moni) processing the response message also successfully with success flag after completion of these 7 minutes. But exactly 5 minutes later getting the error at Java Stack RWB- in communication channel monitoring i.e
    com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.engine.interfaces.messaging.api.exception.MessageExpiredException: Message bd2bf8d0-b2c2-11e0-c383-001cc4fb5cb7(OUTBOUND) expired.  We have set the "runtime-HTTP_TIMEOUT" parameter as 3600. thats why in Integration engine it is processing successfully.
    kindly suggest me how to increase the waiting time for response in Adapter Engine. Exactly after 5 mins getting the above error in rwb, but in Integration Engine getting successful flag after 7 mins until then it is waiting for response with  status flag Log version.

  • Wait step taking longer time than the defined wait time

    Hi,
    We have very simple BPM with 3 steps: Receive, Wait and Send.
    Wait step has following parameters:
    Type: Wait Specified Time Period
    Duration: 1
    Unit: Minutes
    From the above parameters idelly it should wait only for 60 sec and start the next step which is send step. But Wait step is taking following times: 1m 09s,1m 40s, 3m 40s, 1m 41s, 2m 10s, 2m 16s, 2m 46s, 1m 09s, 1m 40s, 3m 39s
    Does anyone know what could be the reason for above longer wait time??
    Thx
    N@v!n

    Hi Naveen,
    How did you measure these times? Tha additional time might be because of the message processing time included or size of the message is bigger to process.. or may be because of the network traffic..!!
    Check the each time stamp from message monitoring tool in RWB and verify for accuracy.

  • How to change wait time-- Urgent

    Hi,
    In monitor screen, under status, I am seeing the wait time date as next month date.
    So the technical status is yellow in color though the data is loaded.
    Where can I change this time.
    Thanks in advance

    Hi,
    When changed Timeout time in Info package it will reflect to particular infopackage only .
    If u changed in RSMO tcoe and settings- menutab
    Waiting time upto status incorrect - it will reflect to all infopackages.
