For failure interval determination, a determination module determines a failure interval for transactions in a transaction queue based on a number of processed transactions. A transaction timeout module fails a first transaction in response to the first transaction not processing within the failure interval.

Failure interval determination

According to one embodiment, a method includes receiving, at a host, an instruction to execute a command that instructs at least one system at a site and in communication with the host via one or more fiber channels to each execute a script, the script being for automatically shutting down components of the at least one system in an order defined by the script, and issuing the command to the at least one system at the site via the one or more fiber channels.

Automated shutdown methodology for a tiered system

Various aspects of the present invention relate to automated shutdown of a tiered system. In one embodiment, at a host, an instruction is received to execute a command that instructs at least one system at a site and in communication with the host via one or more fiber channels to each execute a script, the script being for automatically shutting down components of the at least one system in an order defined by the script. The command is issued to the at least one system at the site via the one or more fiber channels.

Automated shutdown for a tiered system

In one aspect of the present description, in response to receiving a request from a system administrator or other user of a distributed computing system for a log report generated by the system, the system can remotely access various nodes of the system and obtain the log reports at those nodes in response to that user request. In the illustrated embodiment, such remote access and log retrieval may be undertaken whether or not the system administrator is logged into any of the reporting nodes or has direct access to the reporting nodes. As a result, obtaining pertinent log reports from various nodes of the distributed computing system may be facilitated. Other features and aspects may be realized, depending upon the particular application.
