apache as a web proxy
if you want a quick web proxy for your browsers or for anything, you can define a virtualhost in apache2 as follows:
Listen *:8080 <VirtualHost *:8080> ProxyRequests On ProxyVia On <Proxy *> Order deny,allow Allow from all </Proxy> CacheRoot "/tmp" CacheMaxExpire 24 CacheLastModifiedFactor 0.1 CacheDefaultExpire 1 ServerName my-proxy ErrorLog "/opt/csw/apache2/var/log/proxy-error.log" CustomLog "/opt/csw/apache2/var/log/proxy-access.log" common </VirtualHost>
Set ownership and permissions to raw devices using udev
To have the rawdevices in /dev/raw/* have permissions set at reboot, you can add a line to /etc/udev/rules.d/60-raw.rules
added ACTION="add", KERNEL=="raw*", OWNER="informix", GROUP="informix", MODE="0600"

To enable the internal network nic sppp0 in a domain:
svcadm enable svc:/platform/sun4u/dscp:default
To enable the dynamic reconfiguration in a domain:
svcadm enable svc:/platform/sun4u/dcs:default
See the sppp0 nic with the address
sppp0: flags=10010008d1 mtu 1500 index 8

a test to see if communication is ok, from the XSCF run:

pull a proxy port to this server
you can run a non interactive ssh session and pull it to the local host, leave the tunnel running in the background
nohup ssh -g -L 8080:localhost:8080 root@jump -N &
save tsm pasword
to let the tsm client save its password you can add this option to /opt/tivoli/tsm/client/ba/bin/dsm.sys:

Remove disks from vxvm control in a m9000 for dynamic reconfig
If when you want to remove a XSB from a domain you get the message that the OS disks are being used by VxVM, and you know they’re not:
XSCF> deleteboard -c disconnect 09-0 XSB#09-0 will be unconfigured from domain immediately. Continue?[y|n] :y Start unconfiguring XSB from domain. Resource Information ------------------ ------------------------- /dev/dsk/c1t0d0s2 Device being used by VxVM /dev/dsk/c1t1d0s2 Device being used by VxVM XSB#09-0 could not be unconfigured from DomainID 2 due to operating system error.
The message “Device being used by VxVM” can be a bit misleading. They are not in use by VxVM, they’re in use by VxDMP!!!!
To remove this dependency you need to remove them from dmp by doing something like:
vxdisk -o alldgs list | egrep '^c0|^c1' | awk '{ print $1 }' | while read d;do vxdmpadm -f disable path=$d; done
After this you can remove the XSB using “deleteboard -c disconnect” without the “device being used by vxvm” error message
