Question

A company has numerous LPARs hosting database servers, and three versions of the DBMS deployed in the environment. A critical APAR fixes data corruption for one version of the database, but it requires a server reboot. The only inventory information available is a spreadsheet with every LPAR's hostname and root password. Which sequence of tasks will determine which servers are missing the critical APAR, and only apply it to the servers running the affected level of the database?

Options

  • AUse the spreadsheet to populate the /etc/hosts file on the management node.
  • BUse the spreadsheet to create a dsh node list.
  • CConfigure a Systems Director server using the spreadsheet import function.
  • DUse the spreadsheet to create a dsh node list.

Why each option

Creating a dsh node list from the spreadsheet inventory enables the administrator to run distributed commands across all LPARs to identify affected DBMS versions and selectively apply the APAR only to those servers.

AUse the spreadsheet to populate the /etc/hosts file on the management node.

Populating /etc/hosts only provides hostname-to-IP resolution and does not supply a mechanism to remotely execute commands or filter LPARs by DBMS version.

BUse the spreadsheet to create a dsh node list.Correct

The AIX dsh (distributed shell) command uses node list files containing hostnames and credentials to execute commands simultaneously across multiple systems. By building the node list from the spreadsheet, the admin can query each LPAR's DBMS version with a single dsh invocation, construct a filtered node list of only the affected servers, and then run the APAR installation exclusively against that subset - satisfying both the discovery and targeted-apply requirements.

CConfigure a Systems Director server using the spreadsheet import function.

Configuring a Systems Director server is a heavyweight solution that requires substantial setup time and is not practical when the only available starting point is a spreadsheet.

DUse the spreadsheet to create a dsh node list.

This choice is textually identical to choice B and does not represent a distinct approach; B is the recognized correct answer for the dsh node list method.
