indicates that the installed Apache already supports DSO. Otherwise, you need to recompile Apache. The installation and configuration process of Apache is very simple, as shown below: 1. download the httpd-2.0.54.tar.gz (http://httpd.apache.org/) and decompress it to the prepared Directory # Tar zxvf httpd-2.0.54.tar.gz cd httpd-2.0.54 2.

start talking about PHP application code, let's take a look at PHP's DB2 driver. The IBM_DB2 driver supports two methods of connecting to a database: cataloging and non-cataloging. The catalog connection can be a local database (if a DB2 server is running locally) or a remote DB2 server node. The second method is typi

Fast-changing application environments require a flexible mechanism for storing data and passing data between different application tiers. As it turns out, JSON (Java Script Object notation) is an important technology for moving, interactive applications that reduces the overhead of pattern design and eliminates the need for data conversion. DB2 NoSQL JSON enables developers to write applications using the JSON-oriented popular query language created

Tags: User One users MIT action system meaning commit tool definitionDB2 supports session temp table. The table can only exist in a session or in a transaction context and is not visible to other users. DB2 V8 adds support for indexing of temporary tables, which is useful for increasing query speed.The following example illustrates the use of the session temp table:1. Before creating a session temp table, you must create a temporary table spaceCreate

rulesIf you can follow these guidelines before you start, the project you want to adjust will be easier and more likely to succeed.1. Check for known hardware and software issues. Some performance problems may be corrected by simply updating the Software patch or upgrading the hardware. Since it is possible to solve the problem through a simple service pack, why is it a waste of time and energy to check and adjust other parts of the system? That is t

This article will not discuss specific compression algorithms, but will focus on the application scenarios of index compression, that is, how to start index compression and what data distribution is suitable for index compression, which data is not suitable for index compression. How to enable index compression By default, index compression is also enabled after the table is compressed. For unzipped table INDEX compression disabled, you can use the

applications must comply with this Protocol. The specific interface depends on the implementation language, which is irrelevant here. The key point is that all applications must call the lock (resourceId) before accessing the resources controlled by the session lock ). When you no longer need this resource, they should call unlock (). Implement the lock () function The implementation of the lock () function must ensure that the caller can immediately obtain the requested result to grant the loc
