the content of listener.ora file is as follow
# listener.ora Network Configuration File: C:\app\thomas\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
#Default LISTENER.ORA file
(GLOBAL_DBNAME = THOMAS)
(SID_NAME = THOMAS)
(GLOBAL_DBNAME = Oracle8)
(SID_NAME = ORCL)
(ADDRESS = (PROTOCOL = TCP)(HOST = bn-thomas)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
ADR_BASE_LISTENER = C:\app\thomas
how do I extract the port number 1521 and store it in a variable called EXISTING_PORT?
thanks a lot!
