share external database(urgent)

[ivyeibsoft]

Hi all,
When clustering,I expect to build another database for two server instances to share instead of their own default database--hypersonic.
And I want to choose MySql.
Can you help me ?Could you tell me what should I do?
Thank you very much!
I will appreciate for your reply very much!
Best regards!
