But today we are installing and Testing Program Prompt Zend optimizer not installed. this makes me very confused. Why is Zend not installed in such a common space? Then I will check info. PHP, I was surprised to find that the Zend of the server was 1.3.1, and the program I used needed at least 2.6.x or above. No way, I only needed to upgrade my Zend, it will be complicated to upgrade Zend in the future. I will post the specific method to help users w

the final database performance or the executed SQL statement. Therefore, it is particularly important to obtain the current SQL statement running environment when optimizing or debugging the database.

The cost-based optimizer (CBO) occasionally makes some wrong choices when making a full table scan, especially in Oracle7 and Oracle8. There are several situations that can cause this problem, as follows: The highest use mark (high water mark) is too tall: when you want to make a large number of deletions in one table, the maximum use of the tag may be much higher than the actual block number used. Therefore, if you rely on the highest use tag, the CB

The query optimizer supports join operations, and there are three main types of join algorithms in SQL Server: Nested Loop, Sort-merge, and hash join. Although each algorithm is not very complex, in view of performance optimization, the product-level optimizer is often implemented with improved variant algorithms. SQL Server, for example, supports block nested loops, index nexted loops, sort-merge, hash joi

Optimization process Pig philosophy of the second--pigs Are domestic Animals. The user has sufficient control. Specific to the optimization of the logical execution plan, users can choose the appropriate optimization rules according to their own situation (also can be understood as the optimization of this piece has great potential to dig). The logical execution plan is logicalplanoptimizer processed and matched with a series of optimization rules before being compiled into a physical executio

Zend Optimizer is a free PHP optimization software run by the PHP core engine "Zend" founder Zend technology company. According to Zend company revealed that the use of this software in some cases can at least improve performance of more than 30%! This is a good free meal, of course, and now we're going to talk about how to configure the software. Zend opt installation is a fool, the installation Wizard will automatically modify your choice to PHP.in

MySQL employs a cost-based optimizer to determine the most solution to the processing of queries. In many cases, MySQL is able to compute the best possible query plan, but in some cases MySQL does not have enough information about the data to have a "educated" estimate of the data. When MySQL fails to do the "right" thing, you can use the following tools to help MySQL: Use the explain statement to get information about how MySQL handles queries. To

, bump out the last row in the sort order. Return the first N rows from the queue. (If M was specified, skip the first M rows and return the next N rows .) Before 5.6.2, previusly, the server was med this operation by using a merge file for the sort: Scan the table, repeating these steps through the end of the table: Select rows until the sort buffer is filled. Write the first N rows in the buffer (M + N rows if M was specified) to a merge file. Sort the merge file and return the first N rows. (

ORACLE provides two types of SQL optimizer: CBO and RBO. CBO was introduced in ORACLE7, but it was only mature in ORACLE8i. ORACLE has explicitly stated thatIn later versions (ORACLE 10G), RBO will no longer be supported. Therefore, selecting CBO is an inevitable trend. CBO and RBO, as different SQL optimizers, have a significant impact on the execution plan of SQL statements. to port existing applications from RBO to CBOConsider these effects to avoi
