Fabric manager install fails on Linux

Question

Hi folks,trying to install Fabric Manager 3.2(3a) on Redhat 4 U6 and it keeps failing at the same place every time with this error message: 'Cisco Fabric Manager installer 3.2(3a) has encountered a problem and must quit. Cause: nullthis is what i see in the log file:2008-04-14 19:49:52,952 [ INFO] db/share/man/man7/drop_sequence.7.gz could not change directory to '/root/MDS/software' 2008-04-14 19:50:54,684 [FATAL] Install encountered a problem. An installation log can be found at /root/.cisco_mds9000/install.log 2008-04-14 19:50:54,687 [FATAL] if you look in installation log ..you see exact same error.I have tried this install on another machine, same place same error. Also tried an older version of Fabric Manager ..same thing. I am logged in locally to the box as root. Java version is the one that was provided on the cd with Fabric Manager. Has anybody seen this ?Thanks

Elizabeth,would you know what values i need to change, this is what's currently in the file:# Kernel sysctl configuration file for Red Hat Linux # # For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and # sysctl.conf(5) for more details. # Controls IP packet forwarding net.ipv4.ip_forward = 0 # Controls source route verification net.ipv4.conf.default.rp_filter = 1 # Do not accept source routing net.ipv4.conf.default.accept_source_route = 0 # Controls the System Request debugging functionality of the kernel kernel.sysrq = 0 # Controls whether core dumps will append the PID to the core filename. # Useful for debugging multi-threaded applications. kernel.core_uses_pid = 1 Thank you

Java doesn't have enough memory to run the install. Adjust the memory settings in the sysctl.conf file.

these two commands got me going:sysctl -w kernel.shmmax=134217728sysctl -w kernel.shmall=2097152 this makes changes to kernel on the fly but will be lost after reboot, to make them permanent add them to /etc/sysctl.confkernel.shmmax=134217728kernel.shmall=2097152i got these two values from PostgreSQL website.

This is what we have in the sysctl.conf file that's not on yours.
kernel.shmall=7549746
kernel.shmmax=1073741824
# Default kernel.shmmni=4096.
kernel.shmmni=4096
kernel.msgmni=16384
kernel.msgmnb=65536
kernel.msgmax=65536
# Default fs.file-max=392024
fs.file-max=262144
kernel.sem=250 32000 32 2048
vm.swappiness=0
# Default vm.nr_hugepages=0.
vm.nr_hugepages=0
vm.dirty_ratio=10
vm.dirty_background_ratio=5

Some of it might be overkill but it works.

thank you Elizabeth ...i believe many of these values depend on physical memory resources in your system. I had my system admin print his /etc/sysctl.conf file for me and his has a lot of entries just like your file but they did a lot of kernel tuning for Oracle 10g ...i just tried the two lines above and ta-da ..installer finished successfully. Without your hint i had no idea where to look as the error is so unhelpful.
