The FlexDeploy distribution for Tomcat includes the binaries for Tomcat, the FlexDeploy WAR, and the base configurations, leaving only a few simple steps to complete the install. The distribution contains the following components.

...

Step 4. Modify Tomcat configuration file (context.xml) for database connectivity depending on your database type.

Replace the contents of context.xml with the contents the context-<type>.xml if using PostgreSQL or MySQL. The default context.xml file is for Oracle.
Replace URL and Password with the actual values.

File - <FlexDeploy Home>/apache-tomcat-flexdeploy/conf/context.xml

Tip

title	Example JDBC URL (CONNECT_STRING)

Oracle
- The JDBC short format of host:sid:port should not be used. URL must be in the format listed below as we are recommending user of UCP based connection pooling.
  - Example - jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=**HOSTNAME**)(PORT=**PORT**)))(CONNECT_DATA=(SERVICE_NAME=**SERVICE_NAME**)))
  - If RAC is used for the database, multiple nodes can be listed in the address list of the URL or it can point to the scan listener for the cluster. See below sample URL for a RAC implementation that has a primary and secondary scan listener connecting to to a service name GOLD-CLOUD. This includes connection timeout, retry, and retry delay settings.
  - Example - jdbc:oracle:thin:@(DESCRIPTION = CONNECT_TIMEOUT=120) (RETRY_COUNT=20) (RETRY_DELAY=3) (TRANSPORT_CONNECT_TIMEOUT=3) (ADDRESS_LIST =(LOAD_BALANCE=on) (ADDRESS = (PROTOCOL = TCP) (HOST=primary-scan) (PORT=1521))) (ADDRESS_LIST =(LOAD_BALANCE=on) (ADDRESS = (PROTOCOL = TCP) (HOST=secondary-scan) (PORT=1521))) (CONNECT_DATA=(SERVICE_NAME = gold-cloud)))
- For more information about using UCP please check here.
PostgreSQL
- Syntax - jdbc:postgresql://hostname:port/flexdeploy
- Example - jdbc:postgresql://dkrlp01:5432/flexdeploy
- If you are using database name other than flexdeploy, then update URL accordingly.
MySQL
- jdbc:mysql://hostname:port/FD_ADMIN
- Example - jdbc:mysql://dkrlp01:3307/FD_ADMIN
