If we bounce Db do we need to bounce oacore services opmn services on middle tier also ?
As far i know only CM bounce is sufficient.
Yesterday I have bounced Database and restarted ICM,Please check Apache log files and the application.log files for any errors.
Client also confirmed they can access Application. BUt after almost 15 hours they got Internal server errors.
If the Db goes down all JVMs lost connection to db , after db comes up does all oacore/ JVMs gets db connection automatically ?Yes and this explains why the customer was able to access the application after you bounced the database for 15 hours. However, as I mentioned above, it is better if you bounce all the services (since you bounced the database, the application will be inaccessible during this time so bouncing all the application services in the best practice here).
