Modifying a Routing Database Resource
- In Management Console, go to Resources > Spectrum Databases.
-
Select a database that you need to modify in one of these ways:
- Click the name of the database from the Name column.
- Select the check box for the database you need to modify and click Edit button located above the table.
-
Change the Pool Size value if needed, by specifying the
maximum number of concurrent requests you want this database to handle.
Note: This setting represents the number of threads on the components that are listening for service requests from the Spectrumâ„¢ Technology Platform for executing a Spatial routing stage (that is, the maximum number of managed connections). Every web service request enters Spectrum from the platform and is passed to the components. The default value of 4 can be increased to accommodate greater request loads. A pool size that matches the number of CPUs is recommended. The maximum setting should not go above twice the number of the CPU core; for example, on a 4 CPU machine the combined number of threads for all services should not exceed 8. Performance tests should be run with various settings until optimal performance is achieved for the usage.
- Specify the Min memory (MB) and Max memory (MB) heap memory values.
-
From the Network Type, select the type of network that
is applicable for the database. You can choose between
Driving and Pedestrian.
A list of available databases appear in the table below. Each database is listed with its description and vintage.
- Select Override advanced settings, if applicable. This feature allows you to override settings such as additional command line arguments when starting process, properties, and environment variables for remote process.
-
Click Save to update the database.
- You cannot modify Name, Module, and Type fields.
- You can add, remove, or do both in the following cases:
- When a database is not an SPD, you can only remove the datasets from a database. The modify features does not allow adding new datasets.
- When a database is an Spectrum Product Data (SPD), you can add as well as remove datasets.
- The database must contain at least one dataset. If you attempt to save it after removing all the datasets, the portal throws an error.
