In J2SE 5.0, the default method automatically registers the SUNSASL provider as a JCA provider in the JAVA security properties file, which is located in the $ $JAVA _home/jreaib/securitylava.securit

Aerospike-Architecture series of big data typesLarge Data Types (Big Data Type) Big Data bin can store a Large number of object sets. The object type can be Integer/String/Map/List. A single record of Aerospike can contain many such bins. Such a bin allows a large amount of data to be contained in a separate record. The limit is based on the storage capability and there is no maximum value for the record.Th

stored in a buffer cache, and the next call to the same code is made directly from the cache, meaning the same code is compiled only once. NGEN (native Image Generator) compilationThe native Image Generator (Ngen.exe) is a tool for improving the performance of managed applications.

Instead of compiling the original assembly with the

I collected some books developed by WP, almost all of which are in English. I suddenly wanted to try to translate them, not only to train myself, but also to some extent to facilitate other people's Quick Start. The firs

First, you need to expand the domain architecture before installing SCCM to ensure that there will be no problems during the installation process. This is the prerequisite for SCCM installation. The method to expand the domain architecture is very simple, but you need to manually perform the operation as follows: NOTE: If there are multiple DC servers, you must start them. Otherwise, the domain

architecture must be able to cope with emergencies and have enough space for upgrading and resizing to meet the potential business expansion needs. Otherwise, there will always be a busy day. System performance is a service aspect, and upgrading and resizing space is a guarantee for the long-term operation of the system.C) maintainability and manageability: apart from the maintainability caused by flexible system implementation, the selection of syst
