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=134217728
sysctl -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.conf

kernel.shmmax=134217728
kernel.shmall=2097152

i 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.
