Do you mean simultaneous processes from one user?
As much as the system load will tolerate. This is a matter of available memory, process slots, and I/O resources.
Do you mean different simultaneous usernames?
The comment above applies about resources, plus there is an upper limit to the number of usernames a UNIX system can have. Ex Solaris 10 allows 65000 usernames by default.
I think maybe you misunderstand. Weblogic runs as a user and creates processes that connect into oracle. So the oracle kernel has to deal with how many simultaneous users in any case. Oracle scales very well but there are limits to performance.
Guessing you are trying to do some preliminary work on setting up a weblogic server.
Anything like this requires a lot of information - number of users, kinds of transactions and so on. The list is not small.
When you ask a question, giving us the OS, system hardware configuration (memory, disk, etc) is the base requirement. I worked in a place that runs weblogic on servers that are separate from the oracle kernel, for example. We had 500-700 users online.
So in reality there is no decent answer to the questions as asked. Sorry.

NAME
Jifty::DBI::Handle::Oracle - An oracle specific Handle object
SYNOPSIS
DESCRIPTION
This module provides a subclass of Jifty::DBI::Handle that compensates for some of the idiosyncrasies of Oracle.
METHODS
connect PARAMHASH: Driver, Database, Host, User, Password
Takes a paramhash and connects to your DBI datasource.
database_version
Returns value of ORA_OCI constant, see "Constants" in DBD::Oracle.
insert
Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.
build_dsn PARAMHASH
Takes a bunch of parameters:
Required: Driver, Database or Host/SID, Optional: Port and RequireSSL
Builds a dsn suitable for an Oracle DBI connection
blob_params column_NAME column_type
Returns a hash ref for the bind_param call to identify BLOB types used by the current database for a particular column type. The current
Oracle implementation only supports ORA_CLOB types(112).
apply_limits STATEMENTREF ROWS_PER_PAGE FIRST_ROW
takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting with FIRST_ROW;
distinct_query STATEMENTREF
takes an incomplete SQL SELECT statement and massages it to return a DISTINCT result set.
