Configure Database Manager

Database Manager

Read-only field showing the description of the database as shown in the 'Database Manager' List. The format of the description quickly identifies the database, as illustrated here:

{odbc provider}:{user}@{datasource}

Enabled

Select this checkbox to allow the Data Manager to respond to requests for the connection.

Alias

The database Alias. This is the value Enterprise Architect clients will need to enter in the 'Model Name' field of the 'Cloud Connection' screen. Whenever a database manager is created the system will define a value for 'Alias' automatically, but if necessary you can change this value to a more meaningful or appropriate name for your Enterprise Architect and WebEA users.

Database Type

Read-only field showing the DBMS of the defined database, such as Firebird, MySQL, Postgres, SQLSvr or Oracle.

Connection String

Read-only field showing the full connection string used to connect to the database.

Copy Button

A convenient button for copying the connection string to the clipboard.

Max Simultaneous Queries

Type in the maximum number of queries that the Pro Cloud Server can process simultaneously for the selected Database Manager. You can use the up/down arrows to adjust this figure to balance resource usage with concurrent user performance.

There is no explicit limit for this value, but the higher the value the more resources are consumed on your server, without a matching increase in benefit in user performance. Connections are held so briefly that the reduction in user wait time due to more connections being opened is not usually noticeable. If you are reaching the number of queries/connections you have defined here, increase it by small increments.

At regular intervals the Pro Cloud Server will write out log entries that summarizes each database connection's usage, for example:

[AUDIT] sqloledb.1:[email protected],1433.eapos | Free:  10 | Max Active:  12 | Acquisitions:  125 |

The 'Max Active' value indicates that within the audit period there were at most 12 simultaneous queries running, therefore to ensure that queuing does not occur the max simultaneous queries setting should be larger than 12. Perhaps try 15 to start with and afterwards this can be reassessed.

Minimum EA Build

Optional. If you want to ensure that all users of the model are on an appropriate build of Enterprise Architect, type in the lowest build number required.

OSLC Access Code

Optional. Type in the access code that all OSLC clients, including WebEA, are required to send in an HTTP header.

Leave blank to indicate that the OSLC clients are not required to send an access code.

Require a secure and authenticated connection

Select this checkbox to ensure that all clients (such as Enterprise Architect, WebEA and Prolaborate) connecting to this Database Manager use SSL authentication.

Note: Before setting this option, make sure the repository has been enabled for User Security (see Enable Model Security); if the repository is enabled for User Security after setting this value, the Pro Cloud Server will not recognize the correct User Security state until after it has been restarted.

Read-only connection

Select this checkbox to prevent users from modifying the database.

Enable Pro Features (OSLC, WebEA and Integration)

This option is only available in Pro Cloud Server editions. A checked state indicates that the current model has 'Pro Features' enabled, which includes OSLC, WebEA and Integration to external systems.

If this option is disabled then the reason for disabling it will be shown in the text. For example:

No License - There is no license defined or the license has expired

Model Limit Reached - Both the 'Token' and 'Team' editions of the Pro Cloud Server are limited to a certain number of models that can be Pro-enabled; this reason code implies the maximum number of models has already been Pro-enabled

Run Scheduled Chart Generation

When this option is checked the Pro Cloud Server will update Time Series charts in the current model as a schedule task. 

To configure the Scheduled Chart Generation , select the checkbox, then click the Configure button.

• Start Time: The time of day that the schedule task should run
• Number of times to retry: In the event of repeated errors, how many times should the process retry
• Interval between retries: The number of minutes between retries
• Next Run: The calculated next run date and time. Note: this value only updates after the various settings has been saved.

Periodically Generate Diagram Images for WebEA & Prolaborate

This option is only available in Pro Cloud Server editions when a Database Manager has Pro Features enabled.

In order to generate diagram images and linked documents (which are required by WebEA and Prolaborate) a worker can be configured to run periodically; the Pro Cloud Server is capable of automatically starting these workers whenever it starts.

To configure a worker, select the checkbox, then click on the Configure button.

See the Configure Worker Help topic for more details.
