Advanced

The Advanced tab lets you view and change the following options for Distributed Command Execution Manager (DCEM) that are not directly related to running commands:

See the following for more detailed help on the Advanced tab:

Generate output files for the target host

This option controls whether DCEM creates output files for commands run on the target host. By default, command output files are generated on the managed host for commands initiated from DCEM. Deselect this option if you do not want command output to be saved in files on the managed host.

Disable real-time output

This option controls whether DCEM displays detailed output in the Execution Progress dialog, or only creates an HTML report that summarizes command status. This option is deselected by default, indicating that real-time output is displayed in the Execution Progress dialog. To disable display of real-time output, select this option.

Generate a command execution report on this host

This option controls whether an HTML report of command results is created on the managing host. By default, this option is selected, indicating that the report is created each time a command specification is run. To view the report, click the Report button in the Execution Progress dialog. You can also point your browser to the full path and file name to view or print the report.

Generate a new command specification for specific hosts

This option controls whether DCEM creates a command specification to run a command on hosts where the command did not complete successfully. The command specification contains all the information from the original command specification, except that the list of target hosts includes only those hosts on which the command was initially unsuccessful. To rerun the command on these specific hosts:

  1. In the General tab of the DCEM dialog, click the Browse button following the Name field.
  2. In the Browse Command Specifications dialog, select the My Problems tab.
  3. Select the command specification to run from the list.
  4. Click the OK button to return to the main dialog and run the command specification on the specific hosts where the previous attempt was unsuccessful.

Set Maximum Number of Report Directories

This option lets you specify the maximum number of directories that can be created on the managing server for storing command specification reports. Once this maximum is reached, DCEM stops creating additional reports, and a message is displayed when a command is run indicating that a report will not be created. To resume report creation, delete report directories that are no longer needed or increase the maximum number of directories allowed.

Generate output file and HTML command report

Report and output files for a command specification are generated when a command is run, if the corresponding Advanced tab options are selected. The report and output files are created in the same directory, under /home/User/dcem/reports/commandSpecificationName .ReportNumber. The /home/User/dcem/report directory contains the index.html file, which references all run commands. For each command specification a directory is created that contains the standard output and standard error files for each host the command specification was run on. The ReportNumber is the current number of reports allowed. The maximum report value is specified in the Advanced tab, which is the maximum number of directories that can be created on the management server for storing command specification reports. Once this maximum is reached, DCEM stops creating additional reports, and a message is displayed when a command is run indicating that a report will not be created. To resume report creation, delete report directories that are no longer needed in /home/User/dcem/reports/ or increase the maximum number of directories allowed.

For example, a command specification named ls, run for the first time on node 1 and node 2 would produce the following directory structure:
