How to Change the iSQL*Plus Port

1)Stop the iSQL*Plus.

bash-3.00$ isqlplusctl stop
iSQL*Plus 10.2.0.1.0
Copyright (c) 2003, 2005, Oracle. All rights reserved.
iSQL*Plus instance on port 5560 is not running ...

2)Take a backup of the files,

$ORACLE_HOME/host_sid/sysman/config/emoms.properties
$ORACLE_HOME/oc4j/j2ee/isqlplus/config/http-web-site.xml

3)Modify the following parameters in the file $ORACLE_HOME/host_sid/sysman/config/emoms.properties

In my computer hostname is neptune and database is data1, so I edited,/oracle/app/oracle/product/10.2.0/db_1/neptune_data1/sysman/config/emoms.properties

oracle.sysman.db.isqlplusUrl=http\://host.domain\:5561/isqlplus/dynamic
oracle.sysman.db.isqlplusWebDBAUrl=http\://host.domain\:5561/isqlplus/

And,
/oracle/app/oracle/product/10.2.0/db_1/oc4j/j2ee/isqlplus/config/http-web-site.xml



4)Start the iSql*Plus server.

bash-3.00$ isqlplusctl start
And enter new post number to your browser like,
http://neptune:5561/isqlplus/
