Problem

Bitbucket Server is setup manually with Oracle as backend, as opposed to migrating database after setup is complete.

After configuration is complete and bitbucket.properties is created with the required details, the following error(s) appear in the atlassian-bitbucket.log:

1 2 3 4 5 6 7 8 9 .... Caused by: com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: IO Error: Invalid number format for port number .... .... Caused by: java.sql.SQLRecoverableException: IO Error: Invalid number format for port number .... .... Caused by: oracle.net.ns.NetException: Invalid number format for port number ....

Cause

JDBC Url format incorrect in bitbucket.properties.

bitbucket.properties

1 jdbc.url=jdbc:oracle:thin:@//dfw-vu-devodb1.uat.svbank.com:1526:DEVOPSPOCDB

Resolution

Changed the Url as follows:

bitbucket.properties

1 jdbc.url=jdbc:oracle:thin:@//dfw-vu-devodb1.uat.svbank.com:1526/DEVOPSPOCDB

There should be a slash "/" rather than a colon ":" before the database name/SID.
