Oracle Connection Parameters
Parameter |
Mandatory |
Description |
---|---|---|
Data Connection Type |
Yes |
ORACLE is selected by default and cannot be changed. |

Yes |
Name of the data connection to create. Data connection names can contain a maximum of 100 characters. They can contain only letters, digits, underscores (_), and hyphens (-). |
Tag |
No |
Attribute of the data connection to create. Tags make management easier.

Basic and Network Connectivity Configuration |
||
IP Address or Domain Name |
Yes |
Address for accessing the database to be connected. You can enter a public/private IP address or a domain name. |
Port |
Yes |
The port of the database to connect. |
KMS Key |
Yes |
KMS key used to encrypt and decrypt data source authentication information. Select a default or custom key.
NOTE:
When you use KMS for encryption through DataArts Studio or KPS for the first time, the default key dlf/default or kps/default is automatically generated. For more information about default keys, see What Is a Default Master Key?. |
Agent |
Yes |
Oracle is not a fully managed service and cannot be directly connected to DataArts Studio. A CDM cluster can provide an agent for DataArts Studio to communicate with non-fully-managed services. Therefore, you need to select a CDM cluster when creating an Oracle data connection. If no CDM cluster is available, create one through the DataArts Migration incremental package. As a network proxy, the CDM cluster must be able to communicate with Oracle.
NOTE:
If a CDM cluster functions as the agent for a data connection in Management Center, the cluster supports a maximum of 200 concurrent active threads. If multiple data connections share an agent, a maximum of 200 SQL, Shell, and Python scripts submitted through the connections can run concurrently. Excess tasks will be queued. You are advised to plan multiple agents based on the workload. |
