How to increase jms file store size in MAS

 

Steps

In order to increase the file store size we need to update the server.xml for the jmsserver bundle.

The server.xml is added in "Server bundles" option in the MAS administration Suite.

To modify the file we need to find the secret in Openshift associated with the jmsserver bundle (or whatever name you gave the bundle).

Once you are logged to the Suite Administration page:

1.) Access Catalog
2.) Select Manage application tile under Applications tab
3.) From Actions button on upper right select Update configuration option

4.) Click to edit Server bundles option

5.) For your jmsserver bundle, click on View in Additional Properties

6.) In Additional server config you will find the secret name, example: massup-manage-de--sb1--asc--sn

Go to your Openshift Console:

1.) Access WorkLoads --> Secrets

2.) Select your manage project

3.) Filter by your secret name massup-manage-de--sb1--asc--sn

4.) Actions --> Edit Secret

5.) In the example below I am changing the fileStoreSize to 4096 (4GB):

Replace:

<fileStore path="/jmsstore" />

With:

<fileStore path="/jmsstore" fileStoreSize="4096" logFileSize="1024"/>

Note the default is 400MB which is not shown since it is the default, and the logFileSize needs to be 25% of the fileStoreSize.  There is no way to set an unlimited file store size in Liberty.
