Software Distributor Administration Guide (March 2009)

The default value for retry_rpc is 1 and retry_rpc_interval is {0}.
The recommended values for the retry_rpc_interval algorithm are {1 2 4 8 15}
with retry_rpc set at 5. If the agent session fails to start for any reason, the controller
and/or target will attempt to re-connect in the following way (i.e., both options set as
above):
• after 1 minute for the first try
• then 2 minutes for the second try
• then 4 minutes
• then 8 minutes
• finally 15 minutes for the last try
If the number of values for retry_rpc_intervalis less than retry_rpc, the last
value given is repeated until the number of actual retries is equal to retry_rpc.
NOTE: If retry_rpc has a value of zero, no retry is attempted. An initial value of 5
is recommended for WAN environments.
8.6 Retry Command
SD-UX supports options that facilitate retrying operations that have failed. These can
be used in conjunction with the checkpointing features or can start the task from the
beginning.
Each execution of a command records all of the target, software, and option selections
automatically in a session file, command.last. You can also save the session information
to a different file using the GUI. The session files are stored in the directory
$HOME/.sw/sessions. The entire command can be retried by recalling the session
in the GUI or by re-executing the task:
command -S command.last
When a task is retried, any fileset that is up to date (has the same product and filesets
revisions as available or installed and is not in the transient or corrupt state) will not
attempt to be reinstalled (the default behavior), and all other filesets will be retried.
This behavior can be overridden, forcing the retry to start at the beginning of all files,
by setting reinstall=true from either your option setting or the CLI.
If the reinstall_files option is set to true, all files in that fileset are retransferred.
However, although preinstall and postinstall scripts for filesets that are being installed
are executed normally, the file transfer for up to date files can be avoided by leaving
the reinstall_files option equal to false (the default).
When the reinstall_files option is false, the user can also control which attributes
are checked in order to determine if the fileset is already installed or available. If the
reinstall_files_use_cksum option is set to true, the size, mtime, and cksum
attributes are checked.
