Installation on virtual hostnames, problem with message server

Hello,

we installed a sap system crm 7.0 dc7 on a virtual hostname on instance number 00. afterwards we installed qc7 on the virtual hostname also with instance number 00 on AIX with DB2. We have no problem with the message server. Only on messenge server can run. both system are installed on the the physical host, but with a virtual hostname and with a seperate ip-address. any suggestions?

regards,

Alexander

    Hello, I thought from a technial position it should be possible, because they are running on different ips. for example in apache you can create several instances on the same port as long as they have different ip addresses.

      Hi Alexander,

      No, the instance number (and SID) need to be unique to the hardware you are installing on. The SAP system will install on a virtual host, but in the default configuration the SAP ports will listen on all available IP-addresses. You will need to install the second system using another instance number.

      Also, on AIX be aware that the nimsh process will occupy port 3901 - the installation process may default to installing the SCS with instance number 01 which will conflict with j2ee/ms/port.

      Hope this helps,

      Best regards,

    also with instance number 00

    both are 00 ? I do not know AIX, but i'm think you can check for example as on WIN-UNIX system --> the services file, or check

    command like netstat -a and see what both after start try's to use one port .... Why you install both with same number?

    Try to check also dev_disp log in work folder.

    Regards.
