The company originally in the Import Execel file, is an import; that is, each import file should have corresponding Java code to achieve, so in the reading Execel file when there is no problem, these two days, ready to waste the previous practice, unified encapsulation, To be able to parse all the Execel files and return the results as long as the configuration file is available. In the implementation process, just started with the demo, so the Execel file is a full path (similar to C://test/xxx

XML can be used on different platformsProgramData transmission and storage. it is an information transmission tool independent of software and hardware. therefore, it has become the W3C recommendation standard. currently, software and hardware configuration files are generally stored in XML files. XML files are easy to use and can be accessed in any application. access in applicationsThere are two models for operating XML files: Dom (Document Object Model) and stream model. The advantage of Dom

8.2 Opening a Standby Database for Read-Only or Read/Write Access8.2 When a standby database is open for read-only access, users can query the standby database but cannot update it. thus, you can reduce the load on the primary database by using the standby database for reporting purposes. you can periodically open the standby database for

Read/write Lock (Read-write lock)A reviewIn some programs there are reader-writer problems, that is, access to some resources there are two possible situations, one is that access must be exclusive line, that is, the meaning of exclusivity, which is called the write operation, the other is that access can be shared, that is, you can have multiple threads to access a resource at the same time, This is called

SHELL script -- read command, shell script -- read To interact with Linux, it is essential for the script to obtain the keyboard input results. read can read the keyboard input characters. read [-rs] [-a ARRAY] [-d delim] [-n nchars] [-N nchars] [-p prompt] [-t timeout] [var

The comprehensive performance aspect (data security and speed aspect), certainly is the RAID5 is good, the data reads aspect, the RAID1 is fastest, the data security aspect, the RAID1 is best, the data writes aspect, RAID0 fastest. RAID5 combines these advantages. Understanding Disk Array RAIDFirst, function1 High speed access to disk (speed-up): Raid makes a common hard drive into a disk array, writes the data in the host, the RAID controller decomposes the data which the host writes to the da

Tags: and merge expected execution MVCC read return result logs releaseIn MySQL, MVCC is used to implement the Repeatable-read isolation level, because the select operation does not lock the data, and the other reply can modify the data read by the current reply without being blocked, so read and write does not conflic

Let's take a big picture first: SQL statement used: BYS @ ocm1> select dbms_rowid.rowid_relative_fno (rowid) file #, dbms_rowid.rowid_block_number (rowid) block #, deptno from bys. test; FILE # BLOCK # DEPTNO ------------------------------ 4 391 10 For example, the text description analyzes the process of obtaining the required data block when the foreground process sends a query statement: Note:This article does not involve the parsing part of SQL statements, client-to-server interaction, and

In some cases, it is reasonable to send a read request to the backup node of the replica set, for example, a single server cannot handle the read pressure on the application, and the query request can be routed to multiple servers in a replicable set. Most MongoDB drivers now support read preferences (read preference;

Both of these methods exist as abstract methods in the abstract class InputStream ,The JDK API describes both of these: read (): NBSP reads the next byte of data from the input stream, returning 0 to 255 in the range of int byte value. If there are no bytes available since the end of the stream has been reached, -1 is returned. This method is blocked until the input data is available, the end of the stream is detected, or an exception is thrown.

It programmer development Essentials-all kinds of resources download list, history of the most IT resources, personal collection summary. 1.Lock is more object-oriented than the traditional threading model of synchronized, and the lock itself should be an object, similar to a lock in life. Code fragments executed by two threads to achieve the effect of a synchronous mutex, they must use the same lock object. 2. Read and write Lock: divided into

lost.2) Dirty read: Dirty read refers to when a transaction is accessing the data, and the data is modified, and this modification has not been committed to the database, then another transaction also accesses the data, and then used this data.For example:Zhang San's salary was 5000 and transaction a changed his salary to 8000, but transaction a was not yet submitted.MeanwhileTransaction B is reading Zhang

Single block read, block read What is single read? As the name implies, a single block can be read by a single block. The waiting event is db file sequential read. What are the situations of a single block read? Most index scans a

There is a problem when making ERP orders to access warehouse inventory. The order will read if the item is in stock. If there is then the order minus (can order inventory, the physical inventory is not the same) no indication of insufficient inventoryIn the concurrency situation will cause U1 users to order 1 of the goods 1 U2 users also order 1 of the goods 1. There are only 1 items in stock with a number of 1. So when U1 reads out the data and disc

This article describes the use of read () and read (byte[] b) in Java InputStream to see this article for friends who need to know about these two functions.Both of these methods exist as abstract methods in the abstract class InputStream,The JDK API describes both of these:Read (): reads the next byte of data from the input stream, returning an int byte value in the range 0 to 255. Returns 1 if no bytes ha
