  2. You should have $WEBLOGIC_HOME/lib/solaris directory in your LD_LIBRARY_PATH so that the server can load the performance pack (which is a shared library called libmuxer.so).

  3. I tried to install weblogic 6.1 on my PC. I downloaded the weblogic610sp7_win.exe from their site. Although the specification suggests for 128 MB ram(min) and win2000 or above, I went ahead with the installation ( my config is 64 mb ram and win98).
    Now when I run the startweblogic.cmd( I changed all .cmd to .bat as win98 does nt recognise .cmd) i get the following error message.
