I found this in WMB 8.0.0.2 Infocenter which removes the data using session policy automatically.

Also you can use mqsicacheadmin to clear the cache.
I got the below from one presenation on "Big Data Sharing with the Cloud - WebSphere eXtreme Scale and WebSphere Message Broker Integration"
| Quote: |
• Clear out data when you are finished! (Using remove() )
• clear() is not supported – but can be achieved administratively using mqsicacheadmin
|
The following example clears all data from the map named "myMap":
| Code: |
| mqsicacheadmin brokerName -c clearGrid -m myMap |
clearGrid
Clears all data from the specified map in the embedded cache. This command has immediate effect and does not require a broker restart. |

It's amazing what knowledge can be obtained from reading ! That's a great tip Simbu. Thanks for posting.

You really need to do your own homework.

Google is a great resource. You should learn to use it. Please don't post here until you do. Simbu was gracious enough to provide you the answer, but you should be self-sufficient and not need people to run Google searches for you.

mqsicacheadmin command
The mqsicacheadmin command provides information about the global cache that is embedded in a broker. For example, you can find out the size of a map and list the hosts that are participating in the cache. You can also use this command to clear data from a map. See Running the mqsicacheadmin command. |

This is a very useful quote Simbu. Thanks for this! |

Hi Simbu,
I already use that remove method for particular element in MbGlobalMap ,and I want to clear all elements in MbGlobalMap with in JCN .
Shall I use remove for all elements ,Is there any alter native in JCN to remove all elements in MbGlobalMap Grid.
Using command line also I tried , it's working fine. I need to know how to clear bulk of key-value pairs from MbGlobalMap with out using Command line. In JCN is it possible to remove all elements with out iterating.

So you are asking how to shell out to an OS shell from Java? You don't already know how to do this?

Please don't use tinyurl's. I know of at least three corporate networks that block all and any attempt to use them.
Until you click on them you do not have any idea where you will end up. You could end up on a site where just viewing the contents could send you to jail.
This site is read all over the world. What might be ok in the USA can and is against the law in many other places.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |
