log4j trace

My personal conclusion: Recently I saw network programming come across trace statements, but I don't know where to output them. I did not find any materials for one night. Today I finally found them on csdn, the method is as follows: 1. Add a trace statement to MFC 2.

Tried so much, the result is not a good one. May be a version inconsistency issue

If the execution efficiency of a system is relatively low, a better method is to track user sessions and use the tkprof tool to format the output using the sorting function to find out problematic SQL statements. For example, first, use the top command on the OS to find the PID Number 9999 of the process that currently occupies the highest cpu resources; Then find the corresponding sid and serial in the database based on the PID # Select s. sid, s. serial # from v $ session s, v $ process p wher

This is a creation in Article, where the information may have evolved or changed. William Kennedy wrote two articles about go debugging, very good, deliberately translated a bit, deepen memory. This article is one of these: Stack traces in Go. The other is Scheduler tracing in Go. The stack trace represents the stacking trace, which is an ordered collection of one or more stack frames. When the progra
