Home -> Community -> Mailing Lists -> Oracle-L -> HELP on how WebLogic works with ASD
Hi there,
I am investigating the different database backup strategies. It seems that Automated Standby Database is a simple and effective way which may fits into our needs.
We are using EJB (WebLogic 5.1) at the server side and the bankend is Oracle. My questions are:
The database information(login, password, sid) is configured in the weblogic.properties and the deployment descriptor file, and it's looked up through JDNI ( in the entity bean case, it's all handled automatically by WebLogic ). So how would the Weblogic works with ASD if the primary database fails?
Is it congigurable in the property and descriptor file that using the standby database if the primary database fails? How does the WebLogic server in a clustering environment know the switching happens?
If the SD can be used for read-only operations, how can we achieve that by using WebLogic?
It seems to me that the activation of ASD to serve as the primary database involves manul human operation. Is this true? Can this be done automatically?
Your reply will be appreciated.
