Transactions

A transaction is a set of operations done on one Virtual Device.

The utility commits all operations to the management database together when the transaction ends. If the transaction fails, the utility discards all its commands.

Name the Virtual Device with a parameter in the first command (all commands have a parameter to name the Virtual Device). You do not need to name it again in other commands of the same transaction.

You cannot send operations to different Virtual Devices in one transaction.

You cannot start a new transaction until you exit the one before.

When you send commands with the "-o" parameter, you can enter multiple commands (for example: add a Virtual System and then add interfaces and routes to it). Separate the commands with a comma ( , ). All the commands are one transaction. The "-o" parameter does not support explicit transaction commands.

When you send commands with the "-f" parameter, you can use explicit transaction commands. Commands from a file can be one or more transactions:

• If not inside a transaction, the current line is one transaction, which the utility automatically commits. You can write multiple commands in one line (as one transaction), separated with a comma ( , ).
• If currently inside a transaction, the utility processes the lines, but does not take action until the transaction ends.
