Last updated on OCTOBER 27, 2016
Applies to:Oracle Net Services - Version 10.1.0.2.0 to 22.214.171.124 [Release 10.1 to 12.1]
Oracle Database - Enterprise Edition - Version 126.96.36.199 and later
Information in this document applies to any platform.
Oracle Server - Enterprise Edition - Version: 10.1.0.2 to 188.8.131.52
After upgrading the Oracle database using DBUA, you find that the value for LOCAL_LISTENER has been changed in the pfile:
For example, the parameter might have been changed from:
In addition, DBUA would have added a connect string to the local tnsnames.ora file that would make this value resolvable:
(ADDRESS = (PROTOCOL = TCP)(HOST = abc)(PORT = 1532))
The DBUA upgrade log would have an entry similar to the following:
[Thread-30] [9:37:0:605] [NetworkUtils.getOneLocalListenerProtocolAddress:2856] Returning
[Thread-30] [9:37:0:606] [NetworkUtils.getOneLocalListenerProtocolAddress:2856] Returning
[Thread-30] [9:37:0:606] [EMConfiguration.run:228] Setting LISTENER_NAME=CYCLTEST,
LISTENER_HOME=/opt/oracle/10g2cyc02, REP_DB_PORT=1532, REP_DB_HOST=abc,
DBUA is designed to use the tnsnames alias reference using the nomenclature "LISTENER_<sid>" rather than a full connect string for the LOCAL_LISTENER parameter.
The goal of this Note is to answer the following questions:
1. What are the advantages of tnsnames.ora, over inline specification?
2. How to revert the changes done by DBUA to tnsnames.ora file?
