In the CMS GC, using the parameters -xx:+printgcdetails and -xx:+printgctimestamps will output a lot of log information, to understand this information can help us better adjust parameters for higher performance. Let's take a look at the CMS GC log example in JDK1.4.2_10: 39.910: [GC 39.910: [parnew:261760k->0k (261952K), 0.2314667 secs] 262017k->26386k (1048384K), 0.2318679 secs] Cenozoic uses (parnew para

First understand CMS CMS is short for content management system, meaning "Content Management System ". CMS has many templates based excellent designs, which can speed up website development and reduce development costs. The CMS function is not limited to text processing. It can also process images, Flash animatio

1. Mambo-mambo, a foreign CMS system, features very powerful, support to add a lot of components, modules; Rich templates official: http://www.mamboserver.com 2. Limbo-limbo (Lite Mambo), as the name suggests, is evolved from Mambo. The aim is to simplify the original Mambo system and make it more lightweight and compact while inheriting mambo some powerful functions and features. At the same time, limbo support three kinds of installation methods: T

There are more than 1000 well-known CMS manufacturers in the world, and their products have their own characteristics. It is very difficult to select a suitable CMS product from the vast sea of CMS products, there are even consultants in the world who help users select CMS products, such as

Learning hibernate when the concept of cascade relationship is always unclear, especially cascade, inverse silly confused. The following is an example to illustrate briefly.Preparatory work:Start by creating a database with two new tables:Classroom Table classes (field here Province)Student Table student (field here Province)The classroom is a one-to-many relationship with students. then create a new projec

Both of these properties are used in a many-to-many or many-to-many relationship. and inverse is especially used for two-way relationships that we don't need in a one-way relationship. Cascade represents whether a cascade operation is performed, and the inverse represents whether the relationship is maintained by the self. Cascade: The possible values for the

Inverse and Cascade are the two most difficult attributes to master in Hibernate mappings. Both play a role in the object's associated operations. 1. Clarify the role of inverse and cascadeInverse determines whether changes to the collection in the object are reflected in the database, so inverse only works on the collection, which is only valid for One-to-many or Many-to-many (because only the two associations contain collections. One-to-one and Many

Ueditor is a WYSIWYG text Web Editor developed by Baidu Web Front-end R D department. It has powerful front-end editing functions and integrates practical functions such as online map, code highlight, and progress bar upload, it also supports a large number of Baidu frontend applications. Ruishang enterprise CMS is a website content management system for enterprise users. It supports the frontend website editing mode (free). Before ueditor, its built

Switch Port cascade knowledge to improve the route, when the two ports are common ports, namely MDI-X) port and MDI-II port, should use a straight-through cable. When four vswitches are uplinked, the network span can reach 500 meters. This distance is enough for a small network in the same building! Port cascade of twisted pair Switches Cascade uses both common p

Understanding of cascade and inverse in hibernate. Which hibernate book did you buy? Sun weiqin is proficient in hibernate, or is it just that hibernate...I have bought both of them. In general, it is okay. However, in some cases, it is relatively simplified, such as the inverse attribute. The two attributes are the most difficult to understand in learning hibernate.(When I first studied hibernate, I found many articles about these two attributes on t

Cascade Extension The Cascade extension mode is the most conventional and direct extension, and some of the older networks use hubs as cascaded devices. Because the hubs were already quite expensive, most enterprises could not choose a switch as a cascade device. That's because most team users are connected to a hub from a port level on the hub. In this way, the

Serial collector: Single thread, "Stop the World", must stop all worker threads when doing garbage collection threads; Parnew collector (Parallel parallel): Multi-threaded, garbage collection will also stop the worker thread; Both can be used in conjunction with the CMS (concurrent Mark Sweep) collector, and all three are concerned with minimizing the downtime of the user thread when garbage collection is minimized. Parallel (parallel): Refers to m

There are also many types of vswitch ports. Different ports have different functions. Here we will analyze the knowledge of vswitch port cascading and improve the route in all aspects of vswitch port cascading knowledge, A straight-through cable should be used when the two ports that are cascaded are normal ports (MDI-X) ports and MDI-II ports, respectively. When four vswitches are uplinked, the network span can reach 500 meters. This distance is enough for a small network in the same building!

Two classes: Book and booktype) Public class book {Private long ID;Private booktype type;} Public class booktype {Private long ID;} Okay, let's start. Scenario 1 They are not correlated. Case 2 /*** @ Hibernate. Convert-to-one column = "col_booktype_id"*/Public booktype GetType (){Return type;} That is to say, a class has multiple books. For example, many books are historical books and many others are mathematical books. So: Booktype = new booktype ();Book book1 = New Book ();Book1.settype (book

Cascade Policy: Responsible for controlling the association between the object to the object cascade, including update, delete, and so on, the other objects are also affected, such as I delete an object, then it is a many-to-one relationship of the object is also deleted.After using the crawl strategy, after interviewing a sub-operation of the note: Cascadetype.merge Way@OneToOne (

Cascade Delete, such as when you delete a table and then add the keyword, will delete the table and delete the relationship between the tableotherObject1. Cascade delete the information in table A, when the field in table A refers to the field in table B, once the information in the field in B is deleted, the information of table A is also automatically deleted. (When the parent table information is deleted
