Configuring Oracle Database and Oracle Net Services for Oracle DCE Integration

Conﬁguring Oracle DCE Integration 10-11

1. Verify that these lines are in the initialization parameter ﬁle:

REMOTE_OS_AUTHENT=FALSE

OS_AUTHENT_PREFIX=""

2. Verify that the initialization parameter ﬁle does not have a multi-threaded

server (MTS) entry for DCE. For example, an entry such as the following is not

permitted:

mts_dispatchers="(PROTOCOL=dce)(DISPATCHERS=3)"

3. Ensure that you are logged on as a member of the DBA group. Restart the

database instance for the changes to take effect.

4. At the SQL*Plus prompt, deﬁne users. Before doing so, decide whether you are,

or ever will be, operating in a multi-cell DCE environment in which you let

Oracle access across cell boundaries. The way you deﬁne users depends on

whether they are connecting within a single cell or across cell boundaries.

Local Cell:

If users are connecting within a local cell, use the following format:

SQL> CREATE USER server_principal IDENTIFIED EXTERNALLY;

SQL> GRANT CREATE SESSION TO server_principal;

For example:

SQL> CREATE USER oracle IDENTIFIED EXTERNALLY;

SQL> GRANT CREATE SESSION TO oracle;

The entire CELL_NAME/SERVER_PRINCIPAL string must be 30 characters or

less (this is an Oracle Database restriction—not a restriction of the DCE adapter).

For example:

SQL> CREATE USER "CELL1/ORACLE" IDENTIFIED EXTERNALLY;

SQL> GRANT CREATE SESSION TO "CELL1/ORACLE";

Multiple Cells:

Note: The MTS_DISPATCHERS initialization parameter is obsolete

in 10g Release 1 (10.1). See Oracle Database Upgrade Guide for further

details.
