Click on the links above to download and configure SQLcl on your environment. Then configure the connection. For example, to propagate between 2 different ATP instances, download the regional wallet from one of the autonomous instances ( a regional wallet put in tnsnames.ora the connection strings of all your autonomous instances in your tenancy). Then put the content of the wallet in a directory and set
export TNS_ADMIN=<your wallet directory>
Finally edit sqlnet.ora in wallet directory and put the path of the wallet directory
Add to tnsnames.ora other configurations as well in case you want to connect to other Oracle database flavours such as Exadata, on-prem instances, etc.
PROPAGATION OF CHANGES
Either you want to promote all the schema objects from one source to an empty destination or you want to promote changes made in source because software evolutionand versioning, the following procedure will help you.
The script below provides an easy way to promote changes between schemas. For that purpose create a file named as you wanted, for example update.sql with the following (put your appropriate values in the placeholders in bold):
/* source database schema user */ connect <user>/<password>@<sourceconnstring> -- creating a working directory !mkdir <a path in your machine> cd myversion; pwd -- Generates changelogs and controller file for the connected schema lb genschema; /* destination database schema user*/ connect <user>/<password>@<destinationconnstring> pwd -- Applies the specified change log using the current connection lb update -changelog controller.xml; exit;
connect scott/tiger@atpext_tp !mkdir myversion pwd cd myversion; lb genschema; connect scott/tiger@atpext1_tp pwd lb update -changelog controller.xml; exit;
Go to directory where you have put the SQLcl binaries:
./sql -nolog @update.sql

Shortly we’ll explain how to put this together with other automation tasks in a CI/CD pipeline.
That’s all, hope it helps!! 🙂
