VET Change Websphere security configuration to allow non-Security Admin managers to generate heapdump/javacore/core files

Websphere 8.0 introduced new functionality that allows administrators to generate heapdumps/system dump/java cores on demand.
This is very useful for administrators investigating particular problem types.

The default Websphere configuration means that these options are only available to administrators with the following role:
Admin Security Manager

This role gives a number of other security related abilities that our customers are unhappy to give to administrators.
This RFE is to request that these options are granted to the following roles:
- Operator
- Administrator

An alternative to this would be to create a new role and grant the access to that role:
- Troubleshooter

There is a risk that making it easier to generate these will make it easier to obtain contain confidential information e.g. by generating a system dump and analysing that.
This should not be a major concern for the following reasons:
1. The tools/knowledge to successfully analyse a heapdump are not wide spread – there are articles on how to do it but someone analysing a dump would need detailed knowledge of the structures in the heap to be able to find/extract the key information
2. In a default configuration any dumps would be generated onto the Websphere server so they would be protected by server level access restrictions

If this is implemented then please deploy it to version 8 and 9 because Maximo installations can use both versions.

    Hi Alasdair,

    I appreciate what the MBean documentation says but when I have tried to generate these dumps from the WAS console I could not do it unless I granted the Admin Security Manager role to the user that I was logged in as.


    I'm happy to have a webex to demonstrate this in theh WAS console.

    best regards,

    Mark

    The ability to create a heapdump, systemdump or Java Core makes use of the JVM MBean. The documentation for the MBean documents the roles that enable it and AdminSecurityManager is not required, either Operator or Administrator is provided. Any user with Operator access or above can perform this function.

    Hi. please provide some instructions about how to see/use this functionality for a user account that does NOT have the Admin Security Manager role.


    Thanks Mark
