Manually Adding Resources
You can manually add servers and Oracle databases to MgC. To gather details about these resources, you need to install the MgC Agent (formerly Edge) in the source environment.
Preparations
- Create a project on the MgC console.
- Install the MgC Agent in the source intranet environment and connect the MgC Agent to MgC.
- Add resource credentials to the MgC Agent.
Adding a Server
- Sign in to the MgC console. In the navigation pane, under Project, select an application migration project from the drop-down list.
- In the navigation pane, choose Discover > Source Resources.
- On the Servers tab, click Add above the list.
Figure 1 Adding a server
- In the displayed dialog box, configure parameters listed in Table 1 and click Confirm. The system automatically checks the credential status and starts collecting resource details.
Table 1 Parameters for adding a server Parameter
Description
Name
Enter a server name.
MgC Agent
Select the MgC Agent installed in the source environment.
Type
Select the OS type of the source server.
Access IP Address
Enter the IP address of the source server.
If the source server is in the same VPC as the MgC Agent, you can enter the private IP address of the server. Otherwise, you have to enter its public IP address.
Port
Enter the port on the source server that allows access from the MgC Agent.
- By default, port 5985 on Windows source servers must be opened to the MgC Agent. The port cannot be changed.
- By default, port 22 on Linux source servers must be opened to the MgC Agent. You can specify a different port if needed.
Credential
Select the server credential. If the credential is not displayed in the list, go to the MgC Agent console, add the server credential, and synchronize it to MgC.
- After the server is added, view it in the list.
Adding a Database
- Sign in to the MgC console. In the navigation pane, under Project, select an application migration project from the drop-down list.
- In the navigation pane, choose Discover > Source Resources.
- Click the Databases tab.
- Click Add above the list.
Figure 2 Adding a database
- Set the parameters listed in Table 2.
Table 2 Parameters for adding a database Parameter
Description
Name
Enter a name.
MgC Agent
Select the MgC Agent you connected to MgC.
Type
Select Oracle.
IP Address
Enter the IP address for connecting to the source Oracle database server.
Port
Enter the listening port of the source Oracle database. The default value is 1521.
Service Name/SID
Enter the service name of the source database. The default value is ORCL.
You can log in to the Oracle database server and run the following command to view the service name of the database you want to add to MgC:SELECT instance_name FROM v$instance;
Credential
Select the database credential. If the credential is not displayed in the drop-down list, go to the MgC Agent console, add the credential, and synchronize it to MgC. When you add the credential to the MgC Agent, set Resource Type to Database and Authentication to Username/Password.
- Click Confirm. The system automatically starts collecting details about the database. When Collected is displayed in the Deep Collection column, the collection is complete. Click the database name. On the displayed database details page, you can view the collected information.
