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:
- save command output files on the managed host
- generate command report on the managing host
- control real-time output in the command progress dialog
- create a new command specification to rerun a command on hosts where the
command did not run successfully.
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:
- In the General tab of the DCEM dialog, click the Browse
button following the Name field.
- In the Browse Command Specifications dialog, select the
My Problems tab.
- Select the command specification to run from the list.
- 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:
- A /home/User/dcem/report/ls.0001 directory would be created.
- This directory would contain node1.out, node2.out, and
corresponding .err files if any errors were encountered.
- The report ls.html HTML file would be located in /home/User/dcem/report/ls.0001.
