1. Obtain a database copy instance from cureent database pointing to another database.
   For example, asuming we have a connection to an informix database (junit_studio), we want to perform a copy from it to a database named junit_studio_oracle that belongs to a server named oracle.
   Copy

   // Ax.db points to junit_studio
   var dbcopy = Ax.db.dbcopy(Ax.db.of("oracle", "junit_studio_oracle"));
   // in DBStudio
   var dbcopy = Ax.db.dbcopy(Ax.db.of("junit_studio_oracle"));

2. Now, assume we want to copy table account. We can setup a configurator with options like in the example.
   Copy

   var dbcopy = Ax.db.dbcopy(Ax.db.of("junit_studio_oracle"));
   
   //employees
   var event = dbcopy.copy("account", f => {
       // DROP: drop table in destination and create again before copy
       // DELETE: Delete rows in destination
       // TRUNCATE: Execute a truncate command
       // MERGE: (default)
       f.setCopyType("DROP");
       // set a batch size
       f.setBatchSize(1000);
   });   
   // TableCopyEvent
   console.log(event);
   console.log(event.getSourceDatabase());
   console.log(event.getSourceTableName());
   console.log(event.getSourceEncoding());
   console.log(event.getTargetDatabase());
   console.log(event.getTargetTableName());
   console.log(event.getTargetEncoding());
   console.log(event.getRowsDeleted());
   console.log(event.getRowsInserted());

To copy a database you can simply use the tables iterator.

var dbcopy = Ax.db.dbcopy(Ax.db.of("junit_studio_oracle"));
    for (var table of Ax.db.getMetaData().getTables()) {
        var event = dbcopy.copy(table, f => {
            f.setCopyType("DROP");
            f.setBatchSize(1000);
        });
        console.log(event.getRowsInserted() + " rows copied into " + event.getTargetTableName()); 
    }
