The procedure for switching single server mode to database multiplexing mode for the purposes of high reliability and load distribution of the system is explained below.
This procedure is equivalent to the setup procedure explained in "Chapter 6 Setting up Database Multiplexing Mode".
Note
If the data storage destination directory name is not comprised of ASCII characters excluding spaces
Stop the application job and then migrate to a directory with a name that uses only ASCII characters excluding spaces:
Stop the database instance on the primary server.
Change the name of the data storage destination directory to one that uses only ASCII characters excluding spaces.
See
When encrypting the storage data, refer to "Database Multiplexing Mode" in the Operation Guide, and then perform the setup for encryption on the primary and standby servers.
Install on the standby server
Install Symfoware Server on the server to be started as the standby server.
Refer to "Installation" in the Installation and Setup Guide for Server for information on how to install Symfoware Server.
Use ASCII characters excluding spaces in the data storage destination directory.
Stop the application jobs
Stop the application jobs to be connected to the primary server.
Change the primary server settings
To allow connections from the server to be started as the standby server, configure the settings in step 2 and thereafter of "6.3.2 Creating, Setting, and Registering the Primary Server Instance" on the primary server.
Set up database multiplexing mode on the standby server
Refer to "6.4.1 Setting up Database Multiplexing Mode on the Standby Server" for details.
Create the standby server instance and start it
Refer to "6.4.2 Creating, Setting, and Registering the Standby Server Instance" for details.
After the above steps are completed, refer to the remaining explanations in "Chapter 6 Setting up Database Multiplexing Mode" and ensure that the required settings and operations are completed.
