How to Disable Web Based System Manager on AIX 6.1

AIX has a neat feature that allows to manage a system completely from a browser interface. Since AIX 6.1 TL3, this interface runs on port 80, which makes it easy to find it. However there might be several reasons one might not want to run the AIX Web Based System Manager. For example:

  • Something else already running on port 80
  • Save the memory and CPU overhead associated with the System Manager
  • Already using IBM Systems Director

So, if you decide that you do not need the Web Based System Manager, you can disable it very easily with these two simple commands:

stopsrc -s http4websm
rmitab webserverstart

Installing IBM Systems Director on an AIX 6.1 LPAR with a DB2 back-end

IBM Systems Director is a very powerful management tool that comes free with PowerVM (that is: free to anyone that purchases a Power System). I have gathered here the different steps. Most of the information comes from the official documentation: Installing IBM Systems Director on the management server. In this guide I focus on the installation using AIX 6.1 in an LPAR with DB2 as the back-end database server.

  • First, prepare the database as described in Preparing the IBM DB2 Universal Database. The DB2 client can be installed following the steps described in Installing the DB2 9.5 Client on AIX 6.1
  • Then, make a note of the following configuration parameters for the Director installer:

    DbmsApplication = DB2
    DbmsServerName = fqdn_of_db2_server
    DbmsTcpIpListenerPort=database_port (for example 50000)
    DbmsDatabaseName = database_name
    DbmsDatabaseAppHome = path_to_sqllib (for example /home/db2inst1/sqllib)
    DbmsUserId = database_user_name
    DbmsPassword = (encrypted_user_password populated by /opt/ibm/director/bin/

    Create a database for IBM Systems Director (ISD), and make sure you can connect to the DB2 database from the AIX LPAR that will serve for the ISD install.

  • Next, the network is prepared, as described in Preparing firewalls and proxies for IBM Systems Director. Remember to also open up access from the management server to the other LAPRs and servers that ISD will have to access.
  • make sure the ports needed for ISD are available:
    netstat -an | grep LISTEN | egrep "951(0|4|5)"
    If the ports are in use, modify them as follows:
    netstat -an | grep LISTEN | egrep "991(0|4|5)"
    if there is no output, then:
    /var/opt/tivoli/ep/runtime/agent/toolkit/bin/ -unmanaged -port 9910 -jport 9914 -nport 9915 -force
  • Next, AIX needs to be patched if necessary, as described in Preparing to install IBM Systems Director Server on AIX. Since we are on AIX 6.1, there is little to do if all the fixpacks are up to date. Installing CSM is one step I recommend if you have IVM managed systems (having csm.hc_utils already installed from the install CD is necessary):

    mkdir csm
    wget ''
    gtar xvzf csm-aix-
    cd installp/ppc
    inutoc .
    installp -acgXYd . csm.hc_utils
    cd ../../../director (where you unpacked the director download see below if you haven't done that part yet)
    installp -acgXYd . Director.Server.ext.FSPProxy.rte

  • Download IBM Systems Director if not already done from IBM, unpack it, and run the installer:
    mkdir director
    gtar xvzf path_to_download/SysDir6_1_Server_AIX.tar.gz
  • Configure the database access:
    cd /opt/ibm/director/proddata/
    cp cfgdbcmd.rsp cfgdbcmd.rsp-dist
    vi cfgdbcmd.rsp

    Edit the file cfgdbcmd.rsp and select the lines that apply to DB2. Then populate the password with:
    /opt/ibm/director/bin/ -dbAdmin db2_instance_user -dbAdminPW db2_instance_user_pass
    this will take a while to complete, as there are over 1,000 tables to create, with constraints and indexes, and then the tables are pre-populated.
  • Then a final configuration to create the resource manager user ID
    This is very simple, just provide a user id and a password for the ISD to use internally.
  • Now you are ready to start the ISD:
    This will take a while, and it will probably hang if you don’t have enough memory. A minimum of 2GB is necessary.
  • Follow the startup progress:
    /opt/ibm/director/bin/smstatus -r
    The output should be as follows:
    I didn’t time, but it takes over 10 minutes for the ISD to become ready in a small LPAR on a p5

That’s it, from here, you can continue on with the ISD documentation: Configuring IBM Systems Director Server after installation.
Let me know how it goes and how you like ISD.
