要約

If the Bamboo server is paused and later resumed by navigating to ⚙️ > Administration > Manage Apps > Pause Server or Resume Server, the platform may become inaccessible. 

A restart of the server resolves the issue temporarily, allowing users to gain access again. However, the problem can recur if the server is paused and resumed again.

環境

This issue has been observed on Bamboo 9.2.3 but it could potentially affect any supported version.

The database in use is Oracle.

診断

The problem arises when the Bamboo Server is paused and then resumed. An error message appears in the <bamboo-home>atlassian-bamboo.log file: 

WARN [10-BAM::PlanExec:pool-13-thread-3] [PoolBase] HikariPool-2 - Failed to validate connection oracle.jdbc.driver.T4CConnection@1ecdba9 (IO Error: Invalid Operation, NOT Connected). Possibly consider using a shorter maxLifetime value.

原因

The issue is caused by a loss of database connection, resulting from mismatches in the configuration settings between the database driver and the database server. 

ソリューション

To address this issue, increase the wait_timeout setting in the database to align with the default maxLifeTime value, which is typically around 30 minutes. This action, as suggested by the error message, should help mitigate the problem
