WMQ Installation in Linux , Websphere MQ installation in Linux.

 In this post we are going to cover complete installation of websphere messsage queue

There are three basic part to cover installtion

1. Prerequisite to install wmq
2.Kernel configuration
3.Install the websphere mq component

1.Prerequisite to install wmq

Create the user and group and directory

1.step to create user mqm and group mqm

login as root in the linux box

[root@localhost Desktop]# groupadd mqm
[root@localhost Desktop]# useradd -g mqm mqm
[root@localhost Desktop]# passwd mqm
Changing password for user mqm.
New password:
BAD PASSWORD: it is too simplistic/systematic
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.


2. Step Set the kernel configuration

go to the /etc dir and open the file sysctl.conf and change the value for below parameter if in case parameter value is already greater than leave.

kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.shmmax = 268435456
kernel.sem = 500 256000 250 1024
net.ipv4.tcp_keepalive_time = 300

after changing the value in this file then execute the command "sysctl -p"

[root@localhost etc]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
kernel.shmmni = 4096
kernel.sem = 500 256000 250 1024
net.ipv4.tcp_keepalive_time = 300
[root@localhost etc]#

Enter the entry for the mqm user in the limit.conf file in the following location
"/etc/security/limit.conf"

mqm              hard    nofile          10240
mqm              soft    nofile          10240

mqm                      noproc          40966

3. Copy the binary setup websphere mq in the system and extract
    run the command.
./mqlicense.sh -accept
[root@localhost WebSphere_MQ]# ./mqlicense.sh -accept

Install WebSphere MQ Components

At minimum Webspere MQ server installation you must install MQSeriesRuntime and the MQSeriesServer components. However, this example show the minimum installation of the following components
    MQSeriesRuntime
    MQSeriesServer
    MQSeriesClient
    MQSeriesSDK
    MQSeriesSample
    MQSeriesJava
    MQSeriesMan
    MQSeriesJRE
    MQSeriesExplorer

Comman Syntax for each component:-

rpm -ivh MQSeriesRuntime-7.5.0-3.x86_64.rpm
