Centralized Deployment Manager

Hi,

I am currently working on a special requirement pertaining to the WebSphere Deployment Manager (Dmgr).

I am being requested by my Client to come up with a model for Centralized Deployment manager.

The detailed reqmts are as follows:

1) The Dmgr(Most probably V7.0) will sit on a high configuration windows machine.
2) Based on requirements Nodes of version 6.0,6.1 and 7.0 will be federated to this Dmgr.
3) The Dmgr will not be used to manage the WebServers (The Web Servers are in DMZ)
4) The Dmgr should manage the federated Nodes irrespective of whether they are hosted on physical machine or VMWare
5) The Dmgr should manage the nodes hosted on Diff. OSes (Win,Solaris, AIX)
6) The env will be secured and Clustered
7) Different applications uses security Certificate with diff expiration periods (validity).

My Question is

How many of the above are theoretically/technically possible in WAS?
How to manage fix pakcs if the reqmts  2&5 above are possible
Whats the best possible approach/model to implement the above requirements.

Thanks,
Rishi

Q: How many of the above are theoretically/technically possible in WAS?
A: All of them.

Q: How to manage fix pakcs if the reqmts  2&5 above are possible
A: The DM must be at the highest level of all of the V7 AppServer nodes
    Use the UpdateManager, on each (virtual) machine to install the appropriate
    fixpack on each.
    Use the OS specific version of the UpdateInstaller, and the AppServer, and
    you should be all set.

Q: Whats the best possible approach/model to implement the above requirements.
A:  Install WSAS on each machine/OS
     Install the appropriate UpdateInstaller (UPDI) on each machine
     Use the UPDI to update each AppServer
     Federate the AppServers to the active DM
     Have fun.  ;-)

Hi,

Thanks for the detailed information.

From you answers, what I have understood is, If the DMgr is at the highest version (ex V7)

1) Fixpack management of federated nodes is not a major concern for Dmgr Centralization

2) A windows hosted DMgr can manage any version and type of Nodes without any problem (is it vice versa? i e an AIX hosted dmgr can manage windows nodes?)

Let me know whether my understanding is correct.

Thanks,
Rishi

- If the DMgr is at the highest version (ex V7)

  Only a V 7 DM can manage V7 AppServer nodes
  Even more important is that before you install the latest fixpack on any of your V7 AppServer nodes, the DM must have the fixpack installed (before you start the cell anyway).  So, if you are going to have any of your AppServers at 7.0.0.7, then the DM must be at 7.0.0.7 first!

- Fixpack management of federated nodes is not a major concern for Dmgr Centralization

  Correct.

- A windows hosted DMgr can manage any version and type of Nodes without any problem

  Correct.  Remember that all of the WSAS code is Java, so all of the nodes are executing on Java Virtual Machines (JVMs).  So, it doesn't matter what OS is being used by any of the AppServers.

  I tend to prefer Aix, Linux, & Windows for the OS, since the JVMs for those Operating Systems are provided by IBM.  For HP, and Solaris, they use non-IBM JVMs, with all of the required code required by the AppServers provided as Java class libraries.

Does this make sense?

yes HonorGod,

Being everything run as Java code, It makes sense for the cross OS support of WAS for DMGR to Node management

But I have a concern with the following

"if f the DMgr is at the highest version (ex V7), Only a V 7 DM can manage V7 AppServer nodes"

Why its like that? I heard that if the V6.0 DMgr can manage both V6.0 and v5.1 Nodes (see Page 26 in the attached pdf)
Is the above constraint placed newly t in V7.0?

Thanks,
Rishi

Because only a V7 DM know about V7 nodes.

A V6.1 node doesn't have all of the code to interact with a V 7 node.
So, a V6.1 DM can only manage V 6.1 and earlier version AppServers.

So, a V7 DM can manage any earlier kind of node, as well as V 7 nodes.

ok?
