pim data synchronization

change code only becomes SCN2. Global Cache Services Refreshes the SCN in the RAC. Regardless of whether the SCN refreshes in a timely manner, subsequent data queries do not result in database errors. However, during this time, it is possible that the query result is not the latest data, resulting in a read consistency problem. All instances in a RAC environment, this parameter value must be the same. A

1. Brief Introduction: MySQL provides the database replication function after version 3.23.15. This feature allows you to synchronize two databases, master-slave mode (a-> B), and backup mode (A The settings of the MySQL Database Synchronization replication function are reflected in the MySQL configuration file. In Linux, the configuration file is usually in/etc/MySQL/My. CNF or my. CNF, my. CNF is in/etc/My. CNF; in Windows, you can find my In the My

There are some conflicts in SQL Server2005 for adding, deleting, modifying and querying, which can easily cause deadlock. Now there is a database of the Filedetail table is two sets of procedures to operate, a set of procedures to increase, delete, change, another set of procedures responsible for inquiries, the results when the volume of data, it is easy to query the set of procedures to query the data is

Event Cause: Recent research and development reaction, a database from 08 to 12 environment, the occurrence of write operation delay problem;Event Analysis: After troubleshooting problems such as system resource contention, preliminary analysis may be caused by network jitter that causes the synchronization mode AlwaysOn node to frequently have a session timeout waiting to be committed.After troubleshooting, the extended event found an irregular 35202

Label:The functionality of the transaction has been in SQL Server for a long time, because it has recently been a data synchronization scheme, so there is a chance to study it again and snapshots, and found that there are a lot of good features and improvements. Here, as an example of sqlserver2008 's transactional publishing function, the way to publish a subscription briefly introduces the operation Flow,

1. Compared with the original method, trigger/Job + DBLINK can be synchronized and refreshed regularly.2. materialized view refresh modes: Incremental refresh and full refresh.3. Advanced Replication: Multi-master replication and materialized view replication.Multi-master replication supports bidirectional synchronous replication and asynchronous replication. materialized views are used for unidirectional replication,1. Compared with the original method, trigger/Job + DBLINK can be synchronized

This paper describes the method of C # application BindingSource to realize data synchronization by example, which has some reference value for the development of C # database program. The implementation method is as follows:The following code example demonstrates how to use the BindingSource component to bind three controls (two text box controls and one DataGridView control) to the same column in the Data

Synchronizing some tables in SQLServer2005 to the Oracle database, data synchronization between different database types can be achieved using linked servers and SQLAgent.Instance:SQLServer2008 There is a table employ_epl that needs to be synchronized to an EHR system (ORACLE11G), the synchronization steps for implementing the database are as follows:1.

1. Introduction to sersync 1. sersync is developed based on inotify and is similar to inotify-tools. 2. sersync can record changes (including adding, deleting, and modifying) in the monitored directory to the name of a specific file or directory. When Rsync is used, only the changed file or directory will be synchronized. Ii. What are the differences between rsync + inotify-tools and rsync + sersync? 1. Rsync + inotify-Tools (1) inotify-tools can only record changes (including adding, deleting,

business through the stored procedures, etc.3) In addition, we have to consider cachingThe cache here means that not only hibernate,hibernate itself provides a level two cache. Here the cache is independent of the application, is still the memory of the read, if we can reduce the frequent access to the database, it is certainly greatly advantageous to the system. For example, an e-commerce system of commodity search, if a keyword product is often searched, then you can consider this part of the
