Netweaver PI 7.10 - Very Long Startup Time

Hi Everyone,

I have a new install of Netweaver 7.10 and when I execute the sapstart command it takes approximately 10minutes to start. The startup script finishes fairly quickly but I'm only able to log-in 10mins later.

I 'm currently using kernel version 127 and we are using logical hostsnames.

I have also tried to started the database and SCS by itself to see if this doesn't improve the response time but no luck. I've searched all the trace files but nothing indicates what is delaying the startup time.

Has anyone else experienced this or do you have any suggestions?

Here is the Instance Profile:

SAPSYSTEMNAME = IP1

SAPSYSTEM = 30

INSTANCE_NAME = DVEBMGS30

DIR_CT_RUN = $(DIR_EXE_ROOT)/$(OS_UNICODE)/sun_64

    Hi Michael,

    Does it take 10 minutes before you can log on to ABAP, or can you log on to ABAP but does it then take several minutes before you can log on to Java?

    If the delay in on the ABAP side, then what behaviour do you see exactly when you try connecting from your SAPGUI:

    - You get an error pop-up indicating that the instance is not available

    - You get a logon screen but after entering your user ID and password, the session remains stuck (hourglass displayed) for a long time

    During startup the following commands are most useful (I suppose you're on UNIX):

    cd /usr/sap/IP1/DVEBMGS30/work
    # For ABAP:
    tail -f dev_disp
    tail -f dev_w0
    # For Java:
    tail -f dev_server0
    grep "state from" dev_server0

    Regards,

    Mark

    Hi ,

    There could be many resaons for this issue.May be you can try couple of them as below::

    1. Check if all the filesystem have sufficient space.

    2. Ping your host & check if this is having long responce time if yes then this can be network issue.

    3. May be you can have a look at archiver if its full?

    4. Check your GUI version & update it to latest.

    Finally check the responce time in ST03n which part is taking most time .

    Thanks..

      Hi ,

      Please check what are the process running or triggered when you start the SAP via MMC.

      I guess some process utilising resources (CPU usage,PF usage & others)when you start SAP .Many times its observed that process other than related to SAP & your database get trigered & utilise non-required resources .

      Finally check the logs dev_w0 & see if all is normal there.

      Thanks..

    Hi,

    If it is the Java Stack which takes 10 minutes to start then it is unfortunately "normal".

    The java stack is very slow to start.

    On my PI 7.0 system, the start duration of the abap stack is 30 seconds while the start duration of the java stack is more than 10 minutes...

    If you are on windows and use an on-access antivirus, it slows java a lot....

    Regards,

    Olivier

    Hi Everyone,

    Want to thank you for your reponses.

    This issue was more related to the startup of the ABAP system but also impacted the Java side.

    I changed the following parameters localhost values to the actual logical system name:

    icm/HTTP/j2ee_0 = PREFIX=/,HOST=sapip1ci30,CONN=0-500,PORT=5$$00

    icm/server_port_1 = PROT=P4,PORT=5$$04,HOST=sapip1ci30

    And I added the following parameter:

    icm/host_name_full = sapip1ci30.prasa.com

    This reduced the overall start time to just under 5 minutes.

    The ABAP still takes a while and wil continue to investigate it. For now I will set the message as answered.

    Kind Regards and thank you for the input
