Persistent Server Scripting Tool Eliminates Repeated Authentication Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scripting tools for server configuration are inefficient as they require establishing and re-authenticating connections for each instruction, limiting the ability to capture repeatable and sequential configuration steps, and are slow due to the 'one-action-connection' approach.
Innovation Solution
A scripting tool that maintains a persistent connection with the server, allowing multiple instructions to be executed using the same connection, supporting interactive and batch modes, and enabling the use of local variables, loops, and flow-control constructs, which can convert existing configuration files into reusable scripts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a one-action-connection approach is used where each instruction requires establishing and re-authenticating connections, then connection security and state isolation are improved, but operational efficiency and productivity deteriorate due to repeated authentication overhead
Solution Approach 1:
The patent segments the connection lifecycle into distinct phases: authentication phase (one-time secure connection establishment) and execution phase (multiple instructions using the same connection). This segmentation allows the system to maintain strong security during authentication while enabling efficient batch operations during execution, resolving the contradiction between security and productivity.
Solution Approach 2:
The patent implements preliminary authentication and connection establishment before executing multiple instructions. By performing the authentication action in advance and reusing the established connection for subsequent instructions, the system eliminates repeated authentication overhead while maintaining security, thus improving operational efficiency without compromising connection security.
2Reliability
If a one-action-connection approach is used, then state isolation between instructions is improved, but the ability to capture repeatable and sequential configuration steps deteriorates
Solution Approach 1:
The patent introduces dynamic state management within the persistent connection context. The scripting environment maintains execution state (variables, control flow information) across multiple instructions while allowing explicit state resets when needed. This dynamic approach enables the system to adapt between maintaining state for automation purposes and isolating state for reliability, resolving the contradiction between state isolation and configuration automation capability.
Solution Approach 2:
The patent changes the parameter of connection persistence from false (one-action-connection) to true (persistent connection with state). This parameter change enables the scripting tool to capture repeatable and sequential configuration steps with flow-control constructs while maintaining controlled state isolation through explicit reset mechanisms, thus improving configuration automation capability without sacrificing reliability.
3Productivity
If multiple instructions are executed using the same persistent connection, then productivity and automation capability are improved, but connection management complexity increases
Solution Approach 1:
The patent implements self-service connection management where the scripting environment automatically handles connection persistence, state maintenance, and cleanup. The system autonomously manages the complex aspects of persistent connections (state tracking, error handling, resource cleanup) without requiring manual intervention, thus enabling high productivity while masking the underlying connection management complexity from the user.
Data Source
AI summary
The present invention provides a scripting tool through which a user can interact with and execute scripting instructions of a scripting language on a server to perform administrative tasks. It interprets scripting instructions either interactively, supplied one-at-a-time from a command prompt on a scripting interface, or in batches via a script file, and it can be used either online or offline. The scripting tool enables a user to interact with the server in a session-like manner by establishing a persistent connection with the server. Once the connection is established, each instruction that the user enters to configure the server may use the same connection that has already been established. Such “session-permanent-connection” approach eliminates the need for the user to establish and re-authenticate a connection for each instruction. The scripting tool is also capable of converting an existing configuration file into a reusable script that can be used to create duplicate configurations. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
