RE: upgrade to AIX 5I know this is terrible design, but the GUI was = created by a software engineering group that is seperate from the = database group. Its not scalable. So Im trying to come up with a more = scalable method. I have no power to change their gui. It rides on the = database. I have to live with it. This is not a high enough transaction = database to warrant seperate instances.=20
We have a variety of customers. Each of them has their own versions of = data. However, the schema is exactly the same. These tables can get = huge, so we dont want to throw them all into the same schema.
Right now, due to the fact that the GUI has a series of logins that are = the same across clients, each client has its own instance. This isnt = very scalable as we get more business. We have to create another = instance and ingest data to it.=20
Id like to find a way to get all the clients in the same instance with = just different schemas and tablespaces. One thing I may have control = over would be to slightly rename the executable. If you check v$session, = in a client-server application the name of the product connecting to the = database is recording. I can handle security based off of that.=20
My question is what would be the best way? Cant do synonyms for this = since its the same login. I think I saw somewhere that there is a = session based 'set' command where you can say use this schema. I think = it was on asktom and in reference to a question about public synonyms. I = cant find it. Anyone know it?=20
Also is it viable to base a context off of what is in v$sesion with a = logon trigger? How would I 'redirect' all queries to a specific schema?
To stress, I cant change the application. Different group with different = skillsets. Any suggestions?=20
