The integration process is based on the previous SSM integration of the 1.0 sample as a blueprint, coupled with the latest Easyui plug-ins to organize, can be said to be an entry-level integration tutorial, I hope to provide some help for interested people.
With the integration of more and more things, the amount of code has become quite large, paste it does not make any sense, I will share the source code, the bottom will have links.

Example of how to create a single backend process in PHP and a background process
This example describes how to create a single-instance background process in PHP. We will share this with you for your reference. The details are as follows:

, Oracle first writes transaction changes to the redo log. That is to say, before dbwr works, lgwr first writes transaction changes to the redo log.
In the following cases, the lgwr process starts to work:
Commit a transaction (COMMIT ).
Every three seconds.
When the redo information exceeds 1 MB.
The redo log buffer is 1/3 full.
Before the dbwr process writes the dirty buffer to the data file.
