Oracle Database migration-basic and oracle database migrationOracle Database migration-Basics As a developer, We must master database knowledge. However, the company's database is maintained by a dedicated DBA. Generally, we provide an environment address, and then we write crud SQL. In addition, the company's product requirements can be cross-data sources, so that generally do not care about the operations

Java 9 migration notes summary, Java 9 migration issues Summary Collation This article mainly studies some precautions for migrating data to Java 9. Migration type 1. The code is not modularized. First, the code is migrated to JDK 9 to make good use of the APIs of JDK 9. 2. Code is also modularized for Migration Notes

Data Consistency Verification for data migration and data migration It is useful to perform some necessary verification during database migration, for example, whether the number of data items before and after migration is consistent or whether the data is consistent. What should I do at this time? The number of verifi

Log processing is a necessary feature in every project development, and logs are running information that is recorded in other files while the program is running. There are three purposes for exporting logs in an application: 1 Monitor the change of variables in the code, periodically record the data to the file for other applications for statistical analysis work. 2 tracking code run time trajectory, as the basis for future audits. 3 acts as a debugger in an integrated development environment,

From: http://dingjun1.javaeye.com/blog/413993 Reprinted: Http://wangjc-opal.javaeye.com/blog/309924 There is no doubt about the powerful functions of log4j, but in actual applications, it is inevitable that an independent log file needs to be output for a function. How can we separate the required content from the original log, what about creating a separate log file? In fact, you can easily implement this function with a slight configuration based o

-- By Blues (zhaochaohua@sina.com) Part 1 Introduction The advantages of log4j are: 1. By modifying the configuration file, you can determine where the log information is output (console, file,...) and whether it is output. In this way, you can print detailed log information in the system development phase to track the system operation, and close the log output after the system is stable, so that while tracking the system operation, also reduces the a

The original Web project was run on Weblogic8, but now the requirement is to run into JBOSS5, preparing for a later migration to a later version of JBossBecause I did not study WebLogic, so the previous steps have been carried out by others, in the half of the time, due to certain circumstances, and gave me to complete.At this point he encountered two main problems, the following is the main log:2016-03-31 03:36:59,787 ERROR [org.apache.catalina.core.

Cocos2d-x provides the source code for the Libnetwork library, and it also provides visual Studio 2012 project file Libnetwork.vcxproj for the Libnetwork library, which makes porting easier.Tip Some cocos2d-x engineering templates in the solution, there are already libnetwork libraries, the process described in this section is not required.Since the bottom of the Libnetwork library is dependent on the Libcurl library, we will first migrate the Libcurl library as described in the previous section

to the runtime environment when they are compiled. Please set up each of these three dynamic link library files individually.Setting file PropertiesIf the above three steps are completed successfully, we can run the test. The migration of Libcurl Library is very representative, it belongs to the header files and library files with each platform, and there is no source file situation. We can all take this as a transplant for everything.For more inform

can be obtained (which is the inverse of the eigenvalue matrix), and this c is the required composite transformation matrix.For each image to be processed, there are different transition matrix C. The values of the lαβ color space are calculated by using the adaptive processing of color images and shape images. Instead of using a fixed c to process all the images. Although this algorithm pays a little price in the computation time, the adaptive method accords with the color distribution of the
