- Client starts automatically at system boot
- Specify whether or not the client is to start automatically whenever the system starts. The default is that this check box is selected; however, the default setting may change depending on the network environment.
- In normal operation, the client starts automatically at system startup and executes requested processing on the basis of instructions from the connection destination. However, this means that any job the user is executing will be terminated abnormally if installation of another company's software begins during that job. Also, the system uses memory and CPU resources while the client is active, even when the system is not using the client. You can avoid these problems by clearing the Client starts automatically at system boot check box.
- Note that if a client is not started automatically at system startup, it can execute automatic polling only when the system is started. If polling is necessary during system startup for a client that is not started automatically, choose the Execute Job Backlog icon to execute polling.
- This item cannot be specified during setup of client facilities for JP1/Software Distribution Manager or JP1/Software Distribution Client (relay system).
- Client will poll the managing server
- Specify whether or not the client is to poll (monitor for instructions from the managing server).
- Normally, the client executes requested processing on the basis of instructions from the managing server. However, instructions from the managing server may not reach the client in the event of a communications error or if the client PC has not been started. In such cases, the client can execute polling to receive instructions. If you use the client control facility, it is recommended that you perform polling. If the system uses a low-speed WAN, you may want to disable polling to minimize unnecessary data transmissions.
- The default is that the Client will poll the managing server check box is selected. If you enable polling, you must also specify the polling timing.
- Organization of this subsection
- (1) Polling timing
- (2) Polling method
Specify the polling timing. The default is Start polling when the client program starts.
- Start polling when the client program starts
- Select this check box to set polling at the time of system startup. Also select either Execute polling only once or Execute polling once every.
- The default is Execute polling once every. The default polling interval depends on the program.
- For setup of client facilities for JP1/Software Distribution Manager or JP1/Software Distribution Client (relay system):
Polls every two hours.
- For setup of JP1/Software Distribution Client (client) and creation of setup information in an installation set:
Polls every 30 minutes (however, the default value may change depending on the network environment).
- Execute polling only once
- The client polls the managing server only once at system startup.
- Execute polling once every
- The client polls the managing server at a fixed interval. The permitted range of the polling interval is 1 minute to 12 hours. To lighten the network load, specify the largest possible interval.
- The client uses this value as a timer value for monitoring failure recovery when a communications error occurs and the client cannot recognize remote installation instructions.
- The first polling is executed
- Select Before the client starts or After the client starts as the polling timing during system start. If the client has not started at the time of job execution, this setting can control the installation timing of a package with Install when system starts specified. The default is After the client starts.
- When Before the client starts is selected
When the client system starts, polling takes place first and then downloaded packages are installed.
If a package with Install when system starts specified is downloaded by polling during system startup, the package is installed immediately after that. Therefore, installation is completed after the first system startup.
- When After the client starts is selected
When the client system starts, downloaded packages are installed and then polling takes place.
If a package with Install when system starts specified is downloaded by polling, which takes place after starting the client system and installing downloaded packages, this package is not installed until the time of the next system startup.
- Selecting Before the client starts provides the advantage of completing installation at the time of the first system startup. However, if programs are registered in the Software Distribution Client Startup folder, startup of these programs is delayed by installation of packages that are downloaded by polling.
- To start the programs in the Software Distribution Client Startup folder sooner, select After the client starts. In this case, these programs start without waiting for polling.
- For details about the differences in the installation time depending on the polling setting, see 11.2.2 Preparing to install software during system startup in the manual Administrator's Guide Volume 1.
- Maximum polling delay before or after starting the client
- Specifies the timing and delay before polling begins after system startup.
- Start polling at a specified time
- Starts polling anytime before the specified amount of time (in seconds) elapses after the client starts. Specify the polling time in the range from 0 to 300 seconds. The default is 0 seconds. If you specify 0, polling starts at the time of client startup.
- This setting prevents multiple PCs from being connected to the higher system at the same time even when they are started at the same time, thereby distributing the load on the network. If system performance is inadequate to keep up with the number of PCs connected to the higher system, or if the load on the network is too high, you can reduce the load by increasing this setting's value.
- Start polling after waiting
- Starts polling when the specified amount of time (in seconds) has elapsed after the client has started. Specify the amount of time the client stands by in the range from 0 to 7,200 seconds. The default is 0 second. When 0 is specified, polling starts at the same time as startup.
- This setting can delay polling in an environment where polling starts after the client establishes connection with the higher system, such as an environment using IEEE802.1X that requires user authentication when the network is connected.
- In such an environment, set this value based on the amount of time required for login after OS startup.
- Polling is executed
- If you select Execute polling only once and specify Before the client starts for The first polling is executed, you can specify either Every time the system boots or When the system boots for the first time each day. The default is Every time the system boots. This setting is not available during setup of client facilities for JP1/Software Distribution Manager or JP1/Software Distribution Client (relay system).
- Specify the time to execute polling
- Select this check box to execute polling once a day at a specified time. When you select this check box, you must specify a polling execution time. If you change the pooling execution time after executing polling based on the When the system boots for the first time each day setting, no polling takes place on that day when the new polling execution time is reached.
- Polling at a specified time cannot be specified during setup of client facilities for JP1/Software Distribution Manager or JP1/Software Distribution Client (relay system).
Specify the polling method the client will use if it cannot connect to the higher system to be polled (due to a relay system error, for example). The default setting is Hot standby. This item is not available at setup of client facilities for JP1/Software Distribution Manager or JP1/Software Distribution Client (relay system).
Specify this item if you set Poll multiple higher systems on the Connection Destination page.
- Hot standby
- This method polls the relay systems that were set in the Specify Higher Systems dialog box in order of their priorities, starting with the relay system with the highest priority. The client then recognizes the relay systems that can be connected as the higher systems to be polled.
- If connection to a higher system becomes disabled, the client polls the relay systems in sequence, starting each time it polls with the highest-priority relay system. The client thus determines the higher systems to be polled.
- However, you can select one of the following three polling methods as the method to be used when the system starts (first polling):
- Poll all higher systems when the system starts
- Poll only main higher system when the system starts
- Perform polling according to priority when the system starts
- The default is Poll all higher systems when the system starts.
- Multiple hosts
- This method polls all relay systems that were specified in the Specify Higher Systems dialog box.
