6.5 Connect OML4R Client to OML4R Server

Instructions for connecting to an OML4R server.

To connect an OML4R client to an OML4R server, start R using the ORE script:

$ ORE
R> library(ORE)

The following examples connect as user OMLUSER with password OMLUSERpsw:

• For a remote database, specify the Oracle Database service identifier (SID), the host name, and the port for the connection.

  ore.connect(user="OMLUSER", sid="orcl", host="severname", password="OMLUSERpsw",
                 port=1521, all=TRUE)

  Note:

  To avoid specifying the password and other connection details in embedded R scripts, you can use Oracle Wallet. See Create an Oracle Wallet for an Oracle Machine Learning for R Connection.

• For a local database, specify the connection as follows:

  ore.connect("OMLUSER", password="OMLUSERpsw", conn_string="", all=TRUE)
