Suspend and Resume
When you want to update the configuration data or EXPRESSCLUSTER X SingleServerSafe, you can stop the EXPRESSCLUSTER service while continuing the operation. This status is called the suspended status. Returning from the suspended status to normal status is called "resume."The suspend and resume operations request processing of the server. The EXPRESSCLUSTER service must be active when you execute a suspend operation.The following functions stop when the cluster is suspended because the EXPRESSCLUSTER service stops while active resources stay active.All monitor resources stop.
You cannot perform operations on groups or group resources (start/stop).
You cannot display or change the status by using the Cluster WebUI or clpstat command.
The following commands are disabled:
clpstat
clpcl options other than --resume
clpstdn

Remarks
- When the server is shut down, the timeout ratio you specified becomes ineffective.With the -s option, you can only refer to the current timeout ratio. You cannot see other information such as remaining time of extended period.You can see the original timeout value by using the status display command.Monitor resource timeout
# clpstat --mon monitor_resource_name --detail
-
Notes
- This command must be executed by a user with the administrator privilege.The EXPRESSCLUSTER service must be running when you execute this command.When you set the timeout ratio, make sure to specify the extension period. However, if you set "1" for the timeout ratio, you cannot specify the extension period.You cannot specify a combination such as "2m3h," for the extension period.

Remarks
If you suspend an already suspended monitor resource or resume an already started one, this command abends without changing the status of the monitor resource.
-
Notes
- Run this command as a user with the administrator privilege.Check the status of monitor resource by using the status display command or Cluster WebUI.Before you run this command, use the clpstat command or Cluster WebUI to verify that the status of monitor resources is in either "Online" or "Suspend."In the case of a monitor resource of which monitor timing is "Active", if a target resource stops temporarily in the active status, and then the target resource or the group which the target resource belongs to is activated, the monitor resource which has been stopped temporarily cannot detect an error. This is because the monitor resource does not start monitoring.The following are examples of the case described above:
Stops an application monitor that is monitoring application resource temporarily.
Reactivate the application resource or the group that the application resource belongs to.
This reactivation procedure applies both manual and automatic when a monitor resource detects an error and reactivates an application by the recovery operation.If you execute clpmonctrl command with the -v option, "FinalAction Count" is script execution count before final action for following setting.The Execute Script before Final Action check box is selected.
Final Action is No operation.

2.19. Estimating the amount of resource usage (clpprer command)¶
Estimates the future value from changes in the resource usage amount written to the input file and outputs the result to a file. It can also be used to check the result of threshold judgment for estimated data.
-
Command line
clpprer -i <inputfile> -o <outputfile> [-p <number>] [-t <number> [-l]]
-
Description
Estimates the future value from the tendency of the given resource use amount data.
-
Option
-
-i
<inputfile>
¶ The clpprer command specifies the resource data for which a future value is to be obtained.
-
-o
<outputfile>
¶ Specifies the name of the file to which the estimate result is output.
-
-p
<number>
¶ Specifies the number of estimate data items. If omitted, 30 items of estimate data are obtained.
-
-t
<number>
¶ Specifies the threshold to be compared with the estimate data.
-
-l
¶
Valid only when the threshold is set with the -t option.Judges the status to be an error when the data value is less than the threshold.
-
-
Return Value
0
Normal end without threshold judgment
1
Error occurrence
2
As a result of threshold judgment, the input data is determined to have exceeded the threshold.
3
As a result of threshold judgment, the estimate data is determined to have exceeded the threshold.
4
As a result of threshold judgment, the data is determined to have not exceeded the threshold.
5
If the number of data items to be analyzed is less than the recommended number of data items to be analyzed (120), the input data is determined to have exceeded the threshold as a result of threshold judgment.
6
If the number of data items to be analyzed is less than the recommended number of data items to be analyzed (120), the estimate data is determined to have exceeded the threshold as a result of threshold judgment.
7
If the number of data items to be analyzed is less than the recommended number of data items to be analyzed (120), the data is determined to have not exceeded the threshold as a result of threshold judgment.
-
Notes
- This command can be used only when the license for the system monitor resource (System Resource Agent) is registered. (If the license is registered, you do not need to configure system monitor resources for the cluster configuration.)The maximum number of input data items of the resource data file specified with the -i option is 500. A certain number of input data items are required to estimate the amount of resource usage. However, if the number of input data items is large, it takes a considerable amount of time to perform the analysis. So, it is recommended that the number of input data items be restricted to about 120. Moreover, the maximum number of output data items that can be specified in option -p is 500.If the time data for the input file is not arranged in ascending order, the estimate will not be appropriate. In the input file, therefore, set the time data arranged in ascending order.
-
Input file
The input file format is explained below. You need to have an input file, written in the following format, for the resource usage amount for which you want to estimate a result.
The input file format is CSV. One piece of data is coded in the form of date and time, numeric value.Moreover, the data and time format is YYYY/MM/DD hh:mm:ss.File example
2012/06/14 10:00:00,10.0 2012/06/14 10:01:00,10.5 2012/06/14 10:02:00,11.0
-
Examples
The estimation of the future value is explained using a simple example.
When an error is detected in the input data:
If the latest value of the input data exceeds the threshold, an error is assumed and a return value of 2 is returned. If the number of input data items is less than the recommended value (=120), a return value of 5 is returned.
Fig. 2.1 Error detection in the input data¶
When an error is detected in the estimate data:
If the estimate data exceeds the threshold, an error is assumed and a return value of 3 is returned. If the number of input data items is less than the recommended value (=120), a return value of 6 is returned.
Fig. 2.2 Error detection in the estimate data¶
When no threshold error is detected:
If neither the input data nor the estimate data exceeds the threshold, a return value of 4 is returned. If the number of input data items is less than the recommended value (=120), a return value of 7 is returned.
Fig. 2.3 When no threshold error is detected¶
When the -l option is used:
If the -l option is used, an error is assumed when the data is less than the threshold.
Fig. 2.4 Use of the -l option¶
-
Examples
If you use a file written in the specified format and run the clpprer command, you can output the estimate result to a file and check it.
Input file test.csv
2012/06/14 10:00:00,10.0 2012/06/14 10:01:00,10.5 2012/06/14 10:02:00,11.0

3. Notes and restrictions¶
This chapter provides cautions on using EXPRESSCLUSTER X SingleServerSafe, as well as the known problems and how to prevent them.
This chapter covers:
3.1. After starting operating EXPRESSCLUSTER X SingleServerSafe¶
This section provides notes on situations you might encounter after starting to operate EXPRESSCLUSTER.
3.1.1. Restrictions during recovery operation¶
Do not perform the following operations by using the Cluster WebUI or command line while recovery processing is changing (reactivation -> last operation), if a group resource (an application resource, service resource, or other resource) is specified as a recovery target and when a monitor resource detects an error.
Stopping/suspending the cluster
Starting or stopping a group
3.1.2. Executable format files and script files not described in the command reference¶
3.1.3. Notes on the Cluster WebUI¶
If the Cluster WebUI is operated in the state that it cannot communicate with the connection destination, it may take a while until the control returns.
When going through the proxy server, make the settings for the proxy server be able to relay the port number of the Cluster WebUI.
When going through the reverse proxy server, the Cluster WebUI will not operate properly.
When updating EXPRESSCLUSTER X SingleServerSafe, close all running browsers. Clear the browser cache and restart the browser.
Cluster configuration data created using a later version of this product cannot be used with this product.
-
When you continue to edit, click the Stay on this page button.
- Reloading the Web browser (by selecting Refresh button from the menu or tool bar), the dialog box to confirm to save may be displayed.When you continue to edit, click the Stay on this page button.
For notes and restrictions of Cluster WebUI other than the above, see the online manual.
3.1.4. EXPRESSCLUSTER Disk Agent service¶
The EXPRESSCLUSTER Disk Agent service is not used for EXPRESSCLUSTER X SingleServerSafe. Do not start this service.
3.1.5. Issues with User Account Control (UAC) in Windows Server 2012 or later environment¶
In Windows Server 2012 or later or later environment, User Account Control (UAC) is enabled by default. When UAC is enabled, there are following issues.
Monitor Resource
Following resource has issues with UAC.
Oracle Monitor Resource
For the Oracle monitor resource, if you select OS Authentication for Authentication Method and then set any user other than those in the Administrators group as the monitor user, the Oracle monitoring processing will fail.When you set OS Authentication in Authentication Method, the user to be set in Monitor User must belong to the Administrators group.
3.1.6. Screen display of application resource / script resource¶
Because the processes started from the application resource or script resource of EXPRESSCLUSTER are executed in session 0, when you start a process having GUI, the Interactive services dialog detection pop-up menu is displayed. Unless you select Show me the message, GUI is not displayed.
3.1.7. Environment in which the network interface card (NIC) is duplicated¶
- Network Initialization complete wait timeYou can configure this setting in Timeout tab of Cluster Properties. If NIC initialization is completed within timeout, the cluster service starts up.
- ARMDELAY command (armdelay.exe)The cluster service starts up after the time that you set with the command from OS startup.
For more details of above setting and command, please refer to the "Legacy Feature Guide" for EXPRESSCLUSTER X.
3.1.8. EXPRESSCLUSTER service login account¶
The EXPRESSCLUSTER service login account is set in Local System Account. If this account setting is changed, EXPRESSCLUSTER might not properly operate as a cluster.
3.1.9. Monitoring the EXPRESSCLUSTER resident process¶
The EXPRESSCLUSTER resident process can be monitored by using software monitoring processes. However, recovery actions such as restarting a process when the process abnormally terminated must not be executed.
3.1.10. JVM monitor resources¶
When restarting the monitoring-target Java VM, you must first suspend JVM monitor resources or stop the cluster.
When changing the JVM monitor resource settings, you must suspend and resume the cluster.
JVM monitor resources do not support a delay warning of monitor resources.
3.1.11. System monitor resources,Process resource monitor resource¶
To change a setting, the cluster must be suspended.
System monitor resources do not support a delay warning for monitor resources.
- If the date or time setting on the OS is changed while a system monitor resource is operating, that system monitor resource may fail to operate normally.If you have changed the date or time setting on the OS, suspend and then resume the cluster.
No error is detected even after the specified duration for detecting errors has passed.
An error is detected before the specified duration for detecting errors has elapsed.
Up to 26 disks that can be monitored by the disk resource monitoring function of System monitor resources.
4. Error messages¶
This chapter provides information on error messages you might encounter when operating EXPRESSCLUSTER X SingleServerSafe.
