Increasing filesystem space on AIX

Increasing filesystem space on AIX

To check all filesystems:

# df -g

# lslv test (Name of the logical volume)
This will give volume group name

# lsvg rootvg (Volume group name)

Verify free PP and if we have enough space than

# chfs -a size=+1G /filesystem

It will add 1 GB to the filesystem

# df -g (Verify filesystem)

Make sendmail on Solaris listen to more than localhost

Check the current configuration:

# svcprop sendmail grep -i local_only
  config/local_only boolean true
# svccfg -v -s sendmail setprop config/local_only=false
# svcadm refresh sendmail # svcadm restart sendmail

Excluding directories and files in tar command

Create a file with all the dictories and files  that you want to exclude in the tar

# less exclude
 test1

 hello

Execute following command

# tar -cvfX test.tar ./exclude *
a hello excluded

a test/ 0K
a test1 excluded
a test2/ 0K
a test3/ 0K


Extract with tar as usual

# tar -xvf test.tar

 

Setting UP private interface between two zones:

        Setting UP private interface between two zones:

1)      Connect two physical server using cross over cable

2)      ifconfig nxge3 inet 192.168.0.10 netmask 255.255.255.0 broadcast 192.168.0.255

3)      ifconfig nxge3 up

4)      Make changes to the zone so that it will persistent

bash-3.00# zonecfg -z zone

zonecfg:testzone> add net

zonecfg:testzone:net> set address=192.168.0.15

zonecfg:testzone:net> set physical=nxge3

zonecfg:testzone:net> end

zonecfg:testzone> verify

zonecfg:testzone> commit

zonecfg:testzone> exit

5)      Create interface and attach to the zone from the global

# ifconfig nxge3 addif 192.168.0.15 netmask 255.255.255.0 broadcast 192.168.0.255 zone testzone up

Created new logical interface nxge3:1

Oracle settings in /etc/project

Command to check value for project.max-shm-memory

prctl -n project.max-shm-memory -i project user.oracle

Command to increase memory to 96 GB memory for running Process

prctl -n project.max-shm-memory -r -v 96GB -i project user.oracle

Command to Make it permanent by updating /etc/project file

projmod -sK "project.max-shm-memory=(privileged,103079215104,deny)" user.oracle

Command to check all parameters for current user

prctl $$

Command to check all parameters used for Oracle user
