Configure mailx and Send email alert from OS Solaris

 

* Configure in file below:

# vi /etc/mail/cf/cf/email.cf

DMemail.mydomain.com.kh

 

# vi /etc/mail/cf/cf/email.mc

MASQUERADE_AS(`email.mydomain.com.kh')

 

 # vi /etc/mail/main.cf

DSemail.mydomain.com.kh

DMemail.mydomain.com.kh

 

#vgrep mydomain*

 

 * Restart Service sendmail 

# svcadm disable svc:/network/smtp:sendmail

# svcadm enable svc:/network/smtp:sendmail

# svcs -a network/smtp:sendmail

* Send test

/usr/bin/mailx -s "Test Mail" -v hornrim@mydomain.com.kh < /dev/nul

Change hostname in Solaris 11

 1. To list the current hostname (i.e. config/nodename property) :

# svccfg -s system/identity:node listprop config
config                       application
config/enable_mapping       boolean     true
config/ignore_dhcp_hostname boolean     false
config/loopback             astring
config/nodename             astring     labsvr

2. Change the hostname to geekserver by setting the property config/nodename to geekserver

# svccfg -s system/identity:node setprop config/nodename="labserver"

3. Refresh and restart the system/identity:node service for the changes to take effect.

# svcadm refresh system/identity:node
or
# svcadm restart system/identity:node

4. Verify the changes

# svccfg -s system/identity:node listprop config
config                       application
config/enable_mapping       boolean     true
config/ignore_dhcp_hostname boolean     false
config/nodename             astring     labserver
config/loopback             astring     labserver

# hostname
labserver

5. Changes to /etc/hosts

– In Solaris 11, the loopback interface entry acts as the server’s own entry (In Solaris 10 it was the primary interface IP) and thus there is no need to add the hostname entry to the /etc/hosts file.
– But some application installers may fail due to this. So make sure you edit this file and change the hostname.

# cat /etc/hosts
#
# Copyright 2009 Sun Microsystems, Inc.  All rights reserved.
# Use is subject to license terms.
#
# Internet host table
#
::1             localhost
127.0.0.1       localhost    loghost
192.168.1.20    labserver

Change IP Address in Solaris 11

 Check IP Detail
# ipadm show-addr

Delete network interface
# ipadm delete-ip net0

Recreate network interface
# ipadm create-ip net0

Add IP Address to network interface
# ipadm create-addr -T static -a 192.168.10.2/24 net0/v4


if we want to change IP Address from Static to DHCP:

Configure an interface with DHCP:

# ipadm delete-addr net0
# ipadm create-addr -T dhcp net0/v4

Configure DNS client on Solaris 11

List the domains to search and the IP addresses for the DNS name servers, then update the SMF repository.

# svccfg -s network/dns/client
        svc:/network/dns/client> setprop config/search = astring: ("domain.com")
        svc:/network/dns/client> setprop config/nameserver = net_address: (DNS_IP)  
* If we want to remove "delprop config/domain"
        svc:/network/dns/client> select network/dns/client:default
        svc:/network/dns/client:default> refresh
        svc:/network/dns/client:default> quit

Make sure to refresh the service for the changes to take effect.
Update the name service switch information to use DNS.

The first command updates the DNS configuration information in the SMF repository.

    # svccfg -s system/name-service/switch
        svc:/system/name-service/switch> setprop config/host = astring: "files dns"
        svc:/system/name-service/switch> select system/name-service/switch:default
        svc:/system/name-service/switch:default> refresh
        svc:/system/name-service/switch:default> quit

Start the services that are needed to run the DNS client.
 
  # svcadm enable network/dns/client
  # svcadm enable system/name-service/switch
Verify that the DNS client is enabled by using one or both of the following commands:

    # dig EXAMPLE.domain.com
  # getent hosts EXAMPLE.domain.com
The dig command when used alone checks that the DNS client is enabled. The getent hosts command verifies the /etc/nsswitch.conf file's use of the DNS client.

The following example shows how you would set multiple /etc/resolv.conf options.

  # svccg
    svc:> select /network/dns/client
        svc:/network/dns/client> setprop config/options = "ndots:2 retrans:3 retry:1"
    svc:/network/dns/client> listprop config/options
config/options astring     ndots:2 retrans:3 retry:1
         svc:/network/dns/client> exit
  # svcadm refresh dns/client
  # grep options /etc/resolv.conf
options ndots:2 retrans:3 retry:1

Topas command on AIX

Description

The topas command reports selected statistics about the activity on the local system. The command uses the curses library to display its output in a format suitable for viewing on an 80 x 25 character-based display or in a window of at least the same size on a graphical display. The topas command requires the bos.perf.tools and perfagent.tools file sets to be installed on the system.
The topas command can also report a limited set of performance metrics from remote AIX® partitions that belong to the same hardware platform

Creating users and groups for database for AIX server

For AIX® installations, create and configure the oinstall and dba groups and the oracle user on the server that hosts the Oracle database.

About this task
Use the following table to help you create the required users and user groups for the database server.

Procedure

1. Log on to the database server as root.
2. To create a group called oinstall, open an AIX shell and type the following command:

Code:

mkgroup id=500 oinstall
mkgroup id=501 dba

This group is the primary group for the oracle user. This group is the inventory group.
Note: The Oracle database requires these names.
3. Create a user called oracle, assign the initial login group (oinstall), and add the user to the dba group.
• Go to the /usr/sbin/ directory
• Type the following command:

Code:

/usr/sbin/useradd -m -g oinstall -G dba oracle

4. Change the password for the oracle user by using the following command:

Code:

passwd oracle

5. At the New Password prompt, enter a new password.
6. To limit the size of a file the user can create, configure the oracle user by typing the following command:

Code:

chuser fsize=-1 data=-1 stack=-1 rss=-1 nproc=-1 oracle

The following list describes the parameters:
• fsize sets the largest file that a user process can create or extend
• data sets the largest data segment for a user's process
• stack sets the largest process stack segment for a user's process
• rss sets the largest amount of physical memory a user's process can allocate
• nproc Maximum number of processes available to a single user

IBM AIX commands

          As you know, AIX has a vast array of commands that enable you to do a multitude of tasks. Depending on what you need to accomplish, you use only a certain subset of these commands. These subsets differ from user to user and from need to need. However, there are a few core commands that you commonly use. You need these commands either to answer your own questions or to provide answers to the queries of the support professionals. In this article, I'll discuss some of these core commands. The intent is to provide a list that you can use as a ready reference. The behavior of these commands should be identical in all releases of AIX. The exceptions have been noted where that is not true.

Command to display/show Hardware specs of an AIX Server

#  prtconf
In order to be able to read the info, you should off course pipe to more:

#  prtconf | more

Set terminal connection time out (TMOUT TIMEOUT) on AIX

# vi /etc/security/user

# set a 60 min timeout policy for bash shell
TMOUT=3600;
TIMEOUT=3600;
readonly TMOUT TIMEOUT;
export TMOUT TIMEOUT;

Set JAVA_HOME environment variable for root user on AIX

Setting variables in /etc/profile

For setting JAVA_HOME in /etc/profile enter following statements:

    JAVA_HOME=/usr/java6_64/jre
    export JAVA_HOME

    PATH=$JAVA_HOME/bin:$PATH
    export PATH

You have to login again to see the changes. I am using putty, so will re-open it and login with root user.
Verifying variables

To verify your changes you can echo JAVA_HOME and PATH variables.

    # echo $JAVA_HOME
    /usr/java6_64/jre

  # echo $PATH
    /usr/java6_64/jre/bin:/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin

  # which java
    /usr/java6_64/jre/bin/java

Count file on AIX

Count Files

Verb: countFiles

Counts the number of files contained in a directory, and a mask can be used as a filter.

Example:

# cd /tmp/test/
# ls -1 *.txt | wc -l

Command search file in tar on AIX

Overview

    We usually pack multiple files into one single archive using the tar command. Further, tar with the -z option allows us to compress the archive using gzip to save disk space.
    We’ll learn how to do grep on a .tar archive to find which files contain an interesting pattern for us.

Command:

# tar -tvf Folder.tar|grep testing.txt
