We have a migration going on in our environment where all
exalogic servers will be migrated to cloud. In this case there is a possibility
of change in hostnames present in all Connections made previously.
Please suggest how to carry out such changes on a bulk level without having to create all connections (and hence jobs and activities on a bulk level).
Because of the migration, yes you will need to update the connection strings on the .ini files. You can use SED with unix and power shell to update the .ini files.
You can also use the attributes of the sql job with the db change
