Parse sgi stl function static void (* _ set_malloc_handler (void (* _ f )()))() static void (* __set_malloc_handler(void (*__f)()))(){ void (* __old)() = __malloc_alloc_oom_handler; __malloc_alloc_oom_handler = __f; return(__old);} First, you must know the function expression of the function pointer as the parameter and the return function pointer (see FunctionPointer ).Therefore, void (* set_malloc_handler () indicates that set_malloc_hand

It took almost one day to implement the string of sgi stl to the c ++ standard.ProgramLibrary. Now, let's make a summary. String is also one of many containers. It complies with the container design interface and is a random reading container (similar to vector, that is, the memory structure is simpler). Its own iterator design is similar to that of vector, all use passed type pointers for iterative operations. String data is stored directly in Alloc

In 10 Gb, enqueueTX waits for four types: 1.enq: TX In 10g, enqueue TX waits are divided into four categories: 1. enq: TX-row lock contention 2. enq: TX-index contention 3. enq: TX-ITL 4. enq: T In 10g, the enqueue TX wait is

Two days ago, we saw some 00060 (deadlock) alarms in the alert logs. I checked the log file and found some strange phenomena. For example, some locks are generated during insert, and some deadlocks are generated for the same object. So while solving these problems, we carefully studied the Tx lock and summarized various situations that produced the Tx lock. Data Record lockedWe know that all the transaction

Disclaimer: The purpose of this document is to analyze the common tea algorithms of TX. The reference information is based on the information published on the Internet. The key information is also filtered and there is no attack or leakage. The simple encryption algorithm tea is so famous in China, probably because Tx is used in a large number of protocols and local data. Many people on the internet even ca

The Mail Merge function is different from the previously mentioned function of saving all TX documents to the database. The Mail Merge function is to insert specific fields in the database to a specific location in the template document. At the same time, this section also demonstrates how to add the print function based on the Mail Merge function and create the template documents required for mail merge.The source code in this section can be found in

How to find out the record V $ SESSION that causes enq: TX-row lock contention has the following four columns to record the row that causes suspension when enq: TX-row lock contention occurs.

Implementation of Linux under OD-TX-TC xxx function one, od command (1) functionThe OD command is used to display the specified file contents in eight-, decimal, 16-, floating-point, or ASCII-encoded characters, and is typically used to display or view characters in a file that cannot be displayed directly in the terminal.Common files are text files and binary files. The OD command is used primarily to view the values stored in a binary file, interpre

Internal lock or latch (internal locks or latches) for protection of internal structures In Oracle da

This is a very simple question. I have summarized this question. First, it was because it was not as simple as I thought. During the process, I encountered some bumps and bumps, and even made some detours, second, I think about troubleshooting. June 19, around five o'clock P.M., a large number of enq: TX appeared in the database This is a very simple question. I have summarized this question. First, it was because it was not as simple as I thought. Du

This article mainly introduces TM lock in Oracle, understand that when we access the same table object in the database through SQL statements, if more than one user operates on the same table object, it may result in inconsistent data and data inconsistency, please refer to the consistency and atomicity of database transactions. Oracle solves the problem of data inconsistency in multi-threaded situations, mainly through two kinds of locks, one is pessimistic lock, that is, I want to say, the oth
