1）Support automatic reading of database mode to prevent manual input errors
2）When the external database is migrated and "migrate data to the database to be enabled" is not checked, it will automatically detect whether the project versions corresponding to the new and old databases are consistent
After the BI system is configured with an external database, it can ensure the stability of the BI system in case of a cluster environment or a large amount of data.
The user can configure the external database in "initialization" or configure the external database of DB2 type in "platform".
Note: if an external database is configured, do not easily modify the user name and password of the external database, otherwise the project will fail to start.
For modification, please refer to：Modify the external database account password .
The types and versions supported by the external database are shown in the following table:
9.7、8.2、11.1
Note 1: the occupied space needs to be adjusted in combination with the usage. It can be configured according to the size of the webapps / Webroot / WEB-INF / embedded / finedb folder, and the future use size can be estimated according to the actual size, increasing by 1-2 times.
Note 2: the recommended memory is the memory reserved for the engineering configuration library.
Note 3: the external database shall be in the same network segment as the Bi project as much as possible to avoid network fluctuation and other problems.
Create a new database to store platform related data.
Standard database creation statement:CREATE SCHEMA FINEDB
Note: different finebi projects cannot share the same external database, otherwise the data may be disordered.
When the external database is a DB2 database, you need to pay attention to "mode setting" and "log space configuration", as shown below.
When connecting to the DB2 database, there is a schema option. The mode is generally the same as the user name.
Note: during DB2 migration, the user name is highly authorized. There will be a pattern with the same name as the user name. You can also create a new pattern.
If the amount of finedb data is too large and the log space is insufficient, it is likely that an error occurs during the configuration process (sqlcode = - 964, sqlstate = 57011). Therefore, it is necessary to ensure that the log space is sufficient
get db cfg for DATABASENAME
View the log configuration. The reference configuration is as follows:
Modify log file size:
db2 update db cfg for <DATABASENAME> using LOGFILSIZ 8192
Number of modified master log files:
db2 update db cfg for <DATABASENAME> using LOGPRIMARY 50
Number of auxiliary log files modified:
db2 update db cfg for <DATABASENAME> using LOGSECOND 20
Finebi 5.1 does not have a built-in DB2 database driver, so you need to manually add the driver.
1）Close the Bi project.
2）Download the corresponding version of the driver package from the IBM official website and upload it to the project webapps \ Webroot \ WEB-INF \ lib directory.
3）Restart the Bi project.
This method is applicable to configuring external database when logging in data decision system for the first time.
The user can configure the external database when entering the platform for the first time, as shown in the following figure:
Click "configure database" to enter the external database configuration interface, select the database type as DB2, and enter the corresponding information of the actual database. As shown in the following figure:
The description of each setting item is shown in the following table:
Automatic configuration without modification
Section 2.3 new database name
It is forbidden to share the database with other projects. It is recommended to create a new database
The database name can only contain numbers, letters, underscores and "."
The host name can only contain numbers, letters, underscores, "-" and "."
Users need to have create, delete, alter, update, select and insert permissions
Pattern
1）Bi projects of version 5.1.15 and later only support drop-down selection mode
After completing the above settings correctly, click "connect to database" in the mode drop-down box. The system will automatically connect to the database and read the mode. Select it (try to select the mode with the same name as the database user)
Note: if you are prompted that the database connection fails, please check the above settings.
2）Bi projects before 5.1.15 only support manual input mode
The name of the schema is the same as the name of the database user
Wait for some time, and you will be prompted that Successfully enabled the new database . As shown in the following figure:
Note: do not refresh the page during migration.
This method is applicable to configuring external database for the first time after entering the data decision system.
The administrator logs in to the data decision system and clicks "manage> System > General > external database > to be configured", as shown in the following figure:
Input the corresponding information of the actual database and configure the external database. As shown in the following figure:
After waiting for a period of time, a pop-up prompt will pop up: the target database has been successfully enabled. Click determine. As shown in the following figure:
Note 1: do not refresh the page during migration.
Note 2: there is no need to restart after the database configuration is successful.
This method is applicable to migrating to a new database after the external database has been configured.
The administrator logs in to the data decision system and clicks "Manage > System > General > external database > configured", as shown in the following figure:
Description of the "migrate data to the database to be enabled" button:
1）Check "migrate data to the database to be enabled"
When the database is switched, the data of the original external database will be imported into the new database, and the historical data backup file will not be generated under the project.
If platform data already exists in the new database, the original platform data will be cleared before importing data. The prompt is shown in the following figure:
2）Uncheck "migrate data to the database to be enabled"
If the new external database is empty, it prompts that the current data must be migrated to the target database.
If the new external database is not empty
Before migration, the configuration information of the original database will be automatically backed up, and the db.properties.bak file will be generated in the webapps \ Webroot \ WEB-INF \ config directory. As shown in the following figure:
The Bi project of version 5.1.15 and later will automatically detect whether the jar package version corresponding to the data in the target database is consistent with the jar package version of the current project.
If it is inconsistent, a prompt will pop up: unable to enable! Project version required to enable the new database: XXX. Current project version: XXX. Please ensure the project version is consistent!
If the jar package version is consistent, directly enable the new database. After the migration is successful, the prompt is as shown in the following figure:
After waiting for a period of time, a pop-up prompt will pop up: successfully switched to the target database! If there is data difference between the old and new databases, the system operation may be affected. It is recommended to restart the project to ensure normal use.
Click "determine" and restart the Bi project. The migration is successful. As shown in the following figure:
