grid Property Group

The grid property group includes the following properties that you can edit from the Properties table:

ftp.account

Defines the user name with which the product connects to the FTP server. The product uses the FTP properties for Telnet discovery operations. Configure the FTP account for each grid server so the account identifies it by host name only. Do not use a host name with a domain (for example, darkstar.ca.com) or an IP address.

ftp.password

Defines the password that is associated with the ftp.account user.

ftp.port

Defines the FTP server listening port.

Default: 21

ftp.root

Defines the root directory (that is, the FTP home directory) of the FTP server.

heartbeat.expiration.interval

Defines the interval (in seconds) during which the product considers a grid node heartbeat valid. When a grid node updates the heartbeat in the database, it also updates the heartbeat expiration to the current time plus the heartbeat.expiration.interval value. If the grid node does not update the heartbeat by the expiration time, the product considers the grid node unavailable or stopped.

Default: 300

heartbeat.refresh.interval

Defines the interval (in minutes) before the product retrieves data from other grid servers. Each grid node updates a heartbeat row in the database regularly. The constant heartbeat update indicates to other grid nodes that this node is running. For example, if you power the computer down the heartbeat eventually expires. When the heartbeat expires, other grid nodes assume the expired grid node is no longer running.

Default: 60

history.retention.days

Defines the interval (in days) to keep the event and job information about grid servers in the database for reporting.

Default: 14

job.resubmit.delay.ms

Defines the interval (in milliseconds) that the product delays an unprocessed grid job before it resubmits the job.

Default: 5000

max.jobs.master

Defines the maximum number of jobs the master grid server can run simultaneously. To conserve resources for other UI activities, this value is lower by default than it is for grid nodes.

Default: 10

max.jobs.slaves

Defines the maximum number of jobs the slave grid server can run simultaneously. Setting this value too low reduces scaling efficiency; setting this value too high can deplete resources and can cause out-of-memory exceptions.

Default: 20

rpc.connect.timeout.seconds

CA Technologies internal use only.

Default: 15

rpc.reply.timeout.seconds

CA Technologies internal use only.

Default: 0

stess.multiplier

CA Technologies internal use only.

Default: 3

system.wide.max.jobs

Defines the total jobs that all of the grid servers can run simultaneously. Setting this value too high can exhaust database resources, such as the maximum number of connections the product can support.

Default: 100

tcp.base.port

Defines the initial port for grid-to-grid communications. You can install a single UI server and any number of grid nodes on a single computer. When each of these servers starts, it creates a socket for grid-to-grid communications.

Default: 8065

tcp.port.range

Defines the range of contiguous ports from tcp.base.port that are available for grid-to-grid communications. All ports from tcp.base.port through tcp.base.port plus tcp.port.range must be open to your firewall.

Default: 15
