Connection Manager (connectionManager)

Connection Manager configuration

Attribute name Data type Default value Description
agedTimeout A period of time with second precision -1 Amount of time before a physical connection can be discarded by pool maintenance. A value of -1 disables this timeout. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), or seconds (s). For example, specify 30 seconds as 30s. You can include multiple values in a single entry. For example, 1m30s is equivalent to 90 seconds.
connectionTimeout A period of time with second precision 30s Amount of time after which a connection request times out. A value of -1 disables this timeout. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), or seconds (s). For example, specify 30 seconds as 30s. You can include multiple values in a single entry. For example, 1m30s is equivalent to 90 seconds.
id string   A unique configuration ID.
maxConnectionsPerThread int

Minimum: 0

  Limits the number of open connections on each thread.
maxIdleTime A period of time with second precision 30m Amount of time after which an unused or idle connection can be discarded during pool maintenance, if doing so does not reduce the pool below the minimum size. A value of -1 disables this timeout. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), or seconds (s). For example, specify 30 seconds as 30s. You can include multiple values in a single entry. For example, 1m30s is equivalent to 90 seconds.
maxPoolSize int

Minimum: 0

50 Maximum number of physical connections for a pool. A value of 0 means unlimited.
minPoolSize int

Minimum: 0

  Minimum number of physical connections to maintain in the pool. The pool is not pre-populated. Aged timeout can override the minimum.
numConnectionsPerThreadLocal int

Minimum: 0

  Caches the specified number of connections for each thread.
purgePolicy
  • ValidateAllConnections
  • FailingConnectionOnly
  • EntirePool
EntirePool Specifies which connections to destroy when a stale connection is detected in a pool.
ValidateAllConnections
When a stale connection is detected, connections are tested and those found to be bad are closed.
FailingConnectionOnly
When a stale connection is detected, only the connection which was found to be bad is closed.
EntirePool
When a stale connection is detected, all connections in the pool are marked stale, and when no longer in use, are closed.
reapTime A period of time with second precision 3m Amount of time between runs of the pool maintenance thread. A value of -1 disables pool maintenance. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), or seconds (s). For example, specify 30 seconds as 30s. You can include multiple values in a single entry. For example, 1m30s is equivalent to 90 seconds.
