    • JVMJ9GC019E -Xms too large for -Xmx, first of all check -Xms and -Xmx parameters -->

      Connect to "ConfigTool" > Instance_ID...>Servers General, check all parameters (compare to first server for example). Also the JRE version are? Are youdownloa special versionfor SAP?

      OK, I was during the answer, you have found the decision. Success

    Hi Christian !!!

    Probably will not be possible make the connection as you're trying to do, it's not the way you need to perform some specific connection to Visual J2EE Admin with Administrative rights.

    First of all you must verify if the user Administrator is currently enabled to log in Netweaver.

    You could do a simple test trying to connect in http://localhost:port/Ä©ndex.html a service like SystemInfo. Be sure that you are using the same password when you have configured your System Landscape for Netweaver Application Server.

    After this open the Visual Admin and start to configure a new connection directly to dispacther.

    So make sure you are including there the IP of your server, the user "Administrator" (it could be J2EE_Admin once it has all necessary grants to admin NWDI, take a look in your user administration) and correct P4 Port and Password.

    You must be able to "ping" from x terminal or cmd the server you are trying to connect and your remote client must connect directly to dispatcher, again, it's a pretty important point, dispatcher works as a reverse proxy, so if you are not allowed to connect in this way, probably you have issues in you scenario, check network, user grants and ports again.

    J2EE does not work complete.

    I have some other problems.

    It is always the same errormessage in /DVEBMGS00/work/dev_server0 at the start of J2EE

    i had searched all files on the system, and all entrys in DB with configtool and visual administrator, but i can't find this hostname.

    the hostname of the AIX system is p571vc06.

    the hosts file is correct.


    next is a error in

    server0.log = SAP_J2EECluster="" null null null

    if i click in visual administrator on jms_provider

    #1.5 #665FF000600B00760000001A000B90940004573D06EF3437#1221819527803#/System/Server##

    j2eeType=SAP_J2EEServiceRuntimePerNode,SAP_J2EEClusterNode=7913450,SAP_J2EECluster="" null null null ]#

    where is the parameter to fix it? i found nothing in configtool or visual administrator!


    and the third if i click in the transaction ICM Monitor on "jump -> HTTP Server -> show data" i get a message like

    HTTP server information could not be read (rc=1)

    But it is no longtext available.

    i could not find some sap note for this.

    no entry in syslog

    http request to http://host:8101/msgserver/text/logon shows

    version 1.0
    J2EE	p571vc06	50000	LB=1
    J2EES	p571vc06	50001	LB=1

    P4HTTP	p571vc06	50005	LB=1
    SDM	p571vc06	50018	

    logon with Visual Administrator works fine.

    any idea?
