Setting the Time Interval for Space Check on CommServe Database

By default, the CommServe Database is monitored for insufficient disk space every 1 hour. Changing the space check time interval is effective when the services are restarted or at the next monitoring interval.

Use the following steps to change the default space check interval. Changes to the space check interval take effect immediately.

  1. From the CommCell Console ribbon, click Control Panel.
  2. Under the Configure section, click System.
  3. In the Database space check interval box, specify the new check interval (in hours and minutes).
  4. Click OK.

Enabling Connection Timeout for CommCell Console

By default, the connection timeout in the CommCell Console is disabled. You can configure the CommCell Console to disconnect users that have been inactive after a specific period of time, which by default is 180 minutes. You can also modify this timeout interval based on your needs.

Use the following steps to enable the console timeout:

  1. From the CommCell Console ribbon, click Control Panel.
  2. Under the Configure section, click System.
  3. Click the Allow GUI connections to timeout checkbox.
  4. In the GUI Timeout in minutes box, specify the timeout interval in minutes.
  5. Click OK.

Setting the Threshold Size for CommServe Database

The size limit of CommServe database can be set at various threshold levels and events can be generated accordingly in the event viewer. These events are the sent with information, minor, major and critical severity levels at the following default threshold levels:

Severity Level Default Threshold
Information 30
Minor 20
Major 10
Critical 5

The Disk Space Low alert is generated when the threshold level falls below the critical severity level. For information on creating notifications for the Disk Space Low alert, see Configuring Alerts for Low Disk Space.

Use the following steps to modify the default threshold levels:

  1. From the CommCell Console ribbon, click Control Panel.
  2. Under the Configure section, click System.
  3. Specify the new threshold levels for each event severity.
  4. Click OK.

Configuring Space Check for Software Installation and System Directories

Additional settings can be configured to check space requirements, generate events, set time intervals, and set thresholds. By default, Space Check monitors the directories:

  • Every six hours on the CommServe
  • Once per day on the remote machines
  • Whenever services are started on any of the computers within the CommCell

If the disk space is less than 75MB, no new jobs are initiated and no new phases are started for running jobs. If the free space is less than 25 MB, all of the existing jobs are killed by the system. The Disk Space Low alert is generated when the threshold level falls below the critical severity level. For information on creating notifications for the Disk Space Low alert, see Configuring Alerts for Low Disk Space.

Use additional settings to configure space check for software installation and system directories:

Additional Settings Purpose
bCHECK_GALAXY Checks the space requirements for Software Installation and System Directories.
bCHECK_SYSTEM Checks the space requirements for System Directories such as %TEMP% for Windows and tmp or var for Unix.
bCHECK_AUTOUPDATES Every 24 hours, the CVD service contacts the Automatic Updates FTP site to check if the CommServe Cache is up-to-date. If you configured your CommCell environment to install updates automatically, but some updates are missing, the missing updates will be downloaded automatically to the CommServe Cache.
bUSE_EVENTS Generates events in the Event Viewer.
nMACHINE_MAINT_INTERVAL_MINUTES Sets the time interval to check disk space, available updates, available service packs and required upgrades. When this additional setting is created or its value is changed, CVD must be recycled on the client before the new interval starts. When CVD service is recycled, the configured interval is restarted from zero.
nGALAXY_MIN Sets the threshold for minimum space available in the drive for installing software.
nGALAXY_MAX Sets the threshold for maximum space that should be consumed in the software installation directory.
nGALAXYTEMP_MIN Sets the threshold for minimum space available in the drive where software Temp directory resides.
nGALAXYTEMP_MAX Sets the threshold for maximum space that should be consumed in the software Temp directory.
nSYSTEMP_MIN Sets the threshold for minimum space available in the drive where system Temp directory resides.
nSYSTEMP_MAX Sets the threshold for maximum space that should be consumed in the system Temp directory.
nJOBRESULTS_MAX Sets the threshold for maximum space that should be consumed in the JobResults directory. This additional setting is used to set alerts when space used crosses the limit specified by this key. This does not limit the actual size of Job Results folder.
nIDA_MIN Sets the threshold for minimum space available in the drive where iDataAgent directory resides.
nIDA_MAX Sets the threshold for maximum space that should be consumed in the iDataAgent directory.
nSYSVAR_MIN Sets the threshold for minimum space available in the var volume on a Unix computer.
nSYSVAR_MAX Sets the threshold for maximum space that should be consumed in the var volume on a Unix computer.

Use the following steps to configure any of the above additional settings:

  1. From the CommCell Browser, navigate to the Client Computers node.
  2. Right-click the <Client>, and then click Properties.
  3. On the Client Computer Properties dialog box, click Advanced.
  4. Click the Additional Settings tab and then click Add.
  1. In the Name box, type the name of the additional setting. The Category and Type details will be automatically populated.

    Alternatively, you can click Lookup and search for the additional setting using the Find box.

  2. In the Value box, the default interval will be displayed. Type the interval in minutes.
  3. Click OK.
  4. Click OK to save the additional setting configuration.

Clearing Space Check Errors

  10. After the error clears, set the "minimum" additional settings back to the correct values.

Configuring Space Check for ContinuousDataReplicator Agents

For computers with ContinuousDataReplicator installed, additional monitoring is performed to avoid deletion of snapshots (in case maximum space on the COW cache volume or Recovery Point Volume was exceeded).

  • For Windows computers, all volumes and mount points on the client computers are checked verify that the source computer is not running out of disk space. If disk space is found low, replication activity is aborted.
  • For Unix computers, opt, tmp, var and the log volumes are monitored. If you are using QSnap, the COW cache volume is also monitored.

If the remaining free space is less than 20% on any monitored volume or mount point, an event is generated and, if configured, a disk space low alert is sent.

By default, Space Check monitors all drives:

  • Once per day on the remote machines.
  • Whenever services are started on any of the computers within the CommCell.

The nMACHINE_MAINT_INTERVAL_MINUTES additional setting can be configured to set the time interval to check space on all volumes on the client computer with ContinuousDataReplicator agents installed. Changing the Space Check time interval is effective when the services are restarted or at the next monitoring interval.

  1. From the CommCell Browser, navigate to the Client Computers node.
  2. Right-click the <Client>, and then click Properties.
  3. On the Client Computer Properties dialog box, click Advanced.
  4. Click the Additional Settings tab, and then click Add.
