IBM Websphere Portal in linux containers [part2]

Continuing the installation with database transfer from derby to db2 and configuring websphere cluster.

By Kostas Koutsogiannopoulos

In the previous post we created a SLES container with Installation Manager to use it as template and a full installation of Websphere Portal Server with Cumulative Fix 08 to use it as primary node:

~ # lxc-ls --fancy
sles  STOPPED  -     -     -       NO         
wsp1  STOPPED  -     -     -       NO         

We start now with database installation.

Firstly we are cloning the template:

~ # lxc-clone sles dbserver
Created container dbserver as copy of sles

Edit the file /var/lib/lxc/dbserver/config with your network preferences and rw filesystem mounts necessary for db2:

# Common configuration
lxc.include = /usr/share/lxc/config/opensuse.common.conf
# Container specific configuration
lxc.arch = amd64
# Network configuration = veth = lxcbr0 = up                 =         = = 00:16:3e:59:00:b0
lxc.rootfs = /var/lib/lxc/dbserver/rootfs
lxc.utsname = dbserver = proc:rw sys:rw

Then you can boot it and login with ssh -X:

~ # lxc-start -n dbserver

~ # lxc-ls --fancy
dbserver  RUNNING  -     -       NO         
sles      STOPPED  -           -     -       NO         
wsp1      STOPPED  -           -     -       NO         

~# ssh -X

dbserver:~ # 

Extract db2 package inside the container and run the installation:

~ # tar -xvf DB2_10.5.0.3_limited_Lnx_x86-64.tar.gz -C /var/lib/lxc/dbserver/rootfs/IBM_packages/

dbserver:~ # /IBM_packages/server_r/db2setup

db2 installation is creating the user db2inst1 needed for configuration wizard and portal server to connect. When the installation is finished, boot wsp1:

~ # lxc-start -n wsp1

~ # lxc-ls --fancy
dbserver  RUNNING  -     -       NO         
sles      STOPPED  -           -     -       NO         
wsp1      RUNNING   -     -       NO         


Transfering database

IBM Websphere Portal comes with configuration web app running in a different websphere profile. We are connecting to "wsp1" to run the application server's profile where the configuration wizard is running:

wsp1:~ # /opt/IBM/WebSphere/AppServer/profiles/cw_profile/bin/ server1

Use your browser to open this url:

Login with credentials you give at the portal's installation:

Select "Set Up a Cluster":

Select "Database Transfer":

For our configuration we are using db2 instance (obviously) with multiple databases.
At some point you need to copy from database server to the portal server the jdbc drivers:

  • /opt/ibm/db2/V10.5/java/db2jcc4.jar
  • /opt/ibm/db2/V10.5/java/db2jcc_license_cu.jar

You need to give the path of jar files to comfiguration wizard.

At last we are runnning all the manual and automated steps in configuration wizard to transfer the databases to the new database server:

During transfer or after Portal start you can comfirm that the new database server is working well with the command:

db2inst1@dbserver:~> db2 list applications

Auth Id  Application    Appl.      Application Id                                                 DB       # of
         Name           Handle                                                                    Name    Agents
-------- -------------- ---------- -------------------------------------------------------------- -------- -----
DB2INST1 db2jcc_applica 1289                                   WPREL    1    
DB2INST1 db2jcc_applica 1273                                   WPREL    1    
DB2INST1 db2jcc_applica 1340                                   WPJCR    1    
DB2INST1 db2jcc_applica 1339                                   WPJCR    1    
DB2INST1 db2jcc_applica 1358                                   WPJCR    1    
DB2INST1 db2jcc_applica 1338                                   WPJCR    1    
DB2INST1 db2jcc_applica 1290                                   WPJCR    1    
DB2INST1 db2jcc_applica 1341                                   WPCOMM   1    
DB2INST1 db2jcc_applica 1306                                   WPCOMM   1    
DB2INST1 db2jcc_applica 1322                                   WPCUST   1    
DB2INST1 db2jcc_applica 1342                                   WPLM     1    

As you see we have some connections from wsp1 node to the database server.
The transfer database procedure is complete.


Create deployment manager

Connect to configuration wizard:

Select "Set Up a Cluster"

Select "Create a Deployment Manager"

We choose to install deployment manager in the same server as the primary node.

Run all the steps at the end.

Our primary node is now managed by deployment manager.


Create a cluster

Connect to configuration wizard:

Select "Set Up a Cluster"

Select "Create a Cluster"

We use the deployment manager in the same host as our primary node to federate the node

Add another node to the cluster

Connect to configuration wizard:

Select "Set Up a Cluster"

Select "Create an Additional Cluster Node"

We want to create an additional cluster node in a different machine from our primary node.

In order to avoid installation from the begining with all the updates and fixes we can clone the primary node "wsp1" to create our secondary wsp2:

~ # lxc-clone wsp1 wsp2
Created container wsp2 as copy of wsp1

Before booting "wsp2" configure the container editing the file /var/lib/lxc/wsp2/config

In our example:

~ # cat /var/lib/lxc/wsp2/config

# Common configuration
lxc.include = /usr/share/lxc/config/opensuse.common.conf
# Container specific configuration
#lxc.arch = amd64
# Network configuration = veth = lxcbr0 = up = 00:16:3e:9a:45:72
#lxc.rootfs = /var/lib/lxc/wsp1/rootfs
#lxc.utsname = wsp1
lxc.arch                         = amd64                 = veth            = vethwsp2                 = lxcbr0                 =         =            = /var/lib/lxc/wsp1/                = up               = 00:16:3e:92:da:40
lxc.rootfs = /var/lib/lxc/wsp2/rootfs
lxc.utsname = wsp2

Then you can boot wsp2 and delete all the was profiles listed with:

wsp2:~ # /opt/IBM/WebSphere/AppServer/bin/ -listProfiles
[cw_profile, wp_profile, dmgr01]

So we run:

wsp2:~ # /opt/IBM/WebSphere/AppServer/bin/ -delete -profileName cw_profile
wsp2:~ # /opt/IBM/WebSphere/AppServer/bin/ -delete -profileName wp_profile
wsp2:~ # /opt/IBM/WebSphere/AppServer/bin/ -delete -profileName dmgr01

After that we can follow the steps from configuration wizard:

This is a screen from Deployment manager at after succesfull node addition to the cluster. Follow:

Servers > Server Types > WebSphere application servers

In the following post we 'll setup the two IBM HTTP servers in front of the websphere cluster and a load balancer in front of them.
