Change SID for Oracle XE

Question

There is supposedly a procedure for changing the default SID of an XE database on AskTom but I cannot find it. Does anyone have the link for the procedure. Thanks.

Answer 1

1) edit LISTENER.ORA to change the port from 1521 to 1522
2) alter system set LOCAL_LISTENER = (ADDRESS = (PROTOCOL=TCP)(HOST=hostname)(PORT=1522))
3) optionally change the HTTP port using EXEC DBMS_XDB.SETHTTPPORT(8082)
4) restart listener
5) restart database
In Linux (same procedures in Windows, just different commands , slashes and editor)
oracle@fuzzy:~> vi $ORACLE_HOME/
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
      (ADDRESS = (PROTOCOL = TCP)(HOST = fuzzy)(PORT = 1521))

Oh, and don't forget to change any/all client configurations that plan on using direct access
IOW, all TNSNAMES.ORA files should be updated and any stored ports in tools like SQLDeveloper or other things that use JDBC, etc.
