Briefly, tracking the SQL emitted by one client is mainly divided into the following steps: 1 Identify the client program to be tracked to the database connection (followed by session instead), mainly to find the only one to identify a session SID and Serial#. 2 set the corresponding parameters, such as opening the time switch (you can know how long a SQL execution), the location of the file that holds the trace data, the maximum value. 3) Start

as the previous article says, SQL Server provides two capabilities to implement change tracking, and this section focuses on changing Tracking functionality. ActivateChangetrackingwe can activate and use the following steps Changetracking Features:1. Activate change Tracking at the database leveluse the following statement to activate the feature on the database

There are three types of tracking files: 1: Warning log files. Activities during database startup, running, and shutdown. When a problem occurs in the database, you must first check the file named alert_sid.log2: Background trace file. Records the running status of the oracle background process, named sid_processname_processid.t There are three types of tracking files: 1: Warning log files. Activities durin

This article describes the progress tracking of ASIHTTPRequest, including tracking the download progress of a single request, tracking the download progress of a series of requests, and tracking the upload progress of a single request, tracking the upload progress of a serie

GPS User tracking is divided into two modes:1. Real-time tracking: When GPS receives new data from the tracked point, the current view is updated to the extent with the tracking point as the center. This method is updated frequently, efficiency may not be high, but if the time interval between GPS data reception is appropriate, the

With the failure request tracking feature, you can capture the corresponding XML-formatted log when a problem occurs, so that you do not have to reproduce the problem to start troubleshooting. In addition, you can define failure conditions for an application and configure trace events to be based on a URL record. Failure request tracking can be configured at two levels: -At the site level, you can enable

To address the confidentiality of traditional SLAAC addresses, IETF proposes RFC 4941, "IPv6 automatically configures the confidentiality extension of stateless addresses", which is usually referred to as "temporary addresses ". The RFC 4941 standard solution is implemented in the following ways: • A temporary address is an IPv6 address that is repeatedly generated using a random IID. • These temporary addresses contain traditional SLAAC addresses. That is to say, nodes that implement RFC 4941 n

Oracle 8i introduced recovery management RMAN), the first implementation of real Incremental backup. Before RMAN, the database output can also be incremental, but once any part of a table changes, the entire table needs to be overwritten. RMAN Incremental Backup only needs to re-write the modified part in the given data file, which greatly saves space. However, before the 10 GB version, Incremental backup needs to scan the entire data file to determine which data blocks have changed. For large d

Micro-service Distributed Tracking System (Springboot+zipkin)First, what is Zipkin?Zipkin is an open source distributed tracking system, open-source by Twitter, dedicated to collecting timing data for services to address latency issues in microservices architectures, including data collection, storage, discovery, and presentation. Its theoretical model comes from the Google Dapper paper.Each service reports

The author's work mainly aims at the appearance model, constructs a kind of multi-instance online learning

The camera tracking feature of Unity 2D game development TutorialIn the previous chapter, we created a simple 2D game. The sprite in this game has 3 states: idle, left, and right. This looks really cool! But the only 3 states limit the ability of the genie and the imaginary space of the game logic. It seems necessary to let the Elves have more state, and this is the main content of this chapter to explain.Camera T
