Basically I am an oracle dba.
We have a task to switch-over from primary db to standby db and we need
tns entries (host-name) to be modified from
tnsnames.ora file containing tns connection entries
SAP_PROD = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = sape-scan.walmart.net)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = SAP) ) )
sape-scan should get changed to sapi-scan if the tns entry found as SAP_PROD
