  - TRANSACTION_COORDINATOR_STRATEGY
```
static final String TRANSACTION_COORDINATOR_STRATEGY
```
    Specify the TransactionCoordinatorBuilder implementation to use for creating instances of TransactionCoordinator which the interface Hibernate uses to manage transactions.
    Accepts either:
    
    an instance of TransactionCoordinatorBuilder,
    a Class representing a class that implements TransactionCoordinatorBuilder,
    the name of a class that implements TransactionCoordinatorBuilder,
    jta or jdbc
    Since:
    
    5.0
    
    See Also:
    
    JTA_PLATFORM, Constant Field Values
    
    Implementation Specification:
    
    With non Jakarta Persistence bootstrapping, Hibernate will use jdbc as the default which will cause problems if the application actually uses JTA-based transactions.
    
    Default Value:
    
    With Jakarta Persistence bootstrapping, based on the persistence unit's PersistenceUnitInfo.getTransactionType(); otherwise jdbc.
  - JTA_PLATFORM
```
static final String JTA_PLATFORM
```
    Specifies the JtaPlatform implementation to use for integrating with JTA, either:
    
    an instance of JtaPlatform, or
    the name of a class that implements JtaPlatform.
    short name of a class (sans package name) that implements JtaPlatform.
    Since:
    
    4.0
    
    See Also:
    
    JTA_PLATFORM_RESOLVER, Constant Field Values
  - JTA_PLATFORM_RESOLVER
```
static final String JTA_PLATFORM_RESOLVER
```
    Specifies a JtaPlatformResolver implementation that should be used to obtain an instance of JtaPlatform.
    
    Since:
    
    4.3
    
    See Also:
    
    Constant Field Values
  - PREFER_USER_TRANSACTION
```
static final String PREFER_USER_TRANSACTION
```
    When enabled, specifies that the UserTransaction should be used in preference to the TransactionManager for JTA transaction management.
    By default, the TransactionManager is preferred.
    
    Since:
    
    5.0
    
    See Also:
    
    JtaPlatform.retrieveUserTransaction(), JtaPlatform.retrieveTransactionManager(), SessionFactoryBuilder.applyPreferUserTransactions(boolean), Constant Field Values
    
    Default Value:
    
    false as TransactionManager is preferred.
  - JTA_CACHE_TM
```
static final String JTA_CACHE_TM
```
    When enabled, indicates that it is safe to cache TransactionManager references in the JtaPlatform
    
    Since:
    
    4.0
    
    See Also:
    
    Constant Field Values
    
    Default Value:
    
    Generally true, though JtaPlatform implementations can do their own thing.
  - JTA_CACHE_UT
```
static final String JTA_CACHE_UT
```
    When enabled, indicates that it is safe to cache UserTransaction references in the JtaPlatform
    
    Since:
    
    4.0
    
    See Also:
    
    Constant Field Values
    
    Default Value:
    
    Generally true, though JtaPlatform implementations can do their own thing.
  - JTA_TRACK_BY_THREAD
```
static final String JTA_TRACK_BY_THREAD
```
    A transaction can be rolled back by another thread ("tracking by thread") -- not the original application. Examples of this include a JTA transaction timeout handled by a background reaper thread. The ability to handle this situation requires checking the Thread ID every time Session is called. This can certainly have performance considerations.
    
    See Also:
    
    SessionFactoryBuilder.applyJtaTrackingByThread(boolean), Constant Field Values
    
    Default Value:
    
    true (enabled).
  - ALLOW_JTA_TRANSACTION_ACCESS
```
static final String ALLOW_JTA_TRANSACTION_ACCESS
```
    When enabled, allows access to the Transaction even when using a JTA for transaction management.
    Values are true, which grants access, and false, which does not.
    
    See Also:
    
    JpaComplianceSettings.JPA_TRANSACTION_COMPLIANCE, Constant Field Values
    
    Default Value:
    
    false when bootstrapped via JPA; true otherwise.
  - ENABLE_LAZY_LOAD_NO_TRANS
```
static final String ENABLE_LAZY_LOAD_NO_TRANS
```
    Allows a detached proxy or lazy collection to be fetched even when not associated with an open persistence context, by creating a temporary persistence context when the proxy or collection is accessed. This behavior is not recommended, since it can easily break transaction isolation or lead to data aliasing; it is therefore disabled by default.
    
    See Also:
    
    SessionFactoryBuilder.applyLazyInitializationOutsideTransaction(boolean), Constant Field Values
    
    Default Value:
    
    false (disabled)
  - ALLOW_UPDATE_OUTSIDE_TRANSACTION
```
static final String ALLOW_UPDATE_OUTSIDE_TRANSACTION
```
    When enabled, allows update operations outside a transaction.
    Since version 5.2 Hibernate conforms with the JPA specification and disallows flushing any update outside a transaction.
    Values are true, which allows flushing outside a transaction, and false, which does not.
    The default behavior is to disallow update operations outside a transaction.
    
    Since:
    
    5.2
    
    See Also:
    
    SessionFactoryBuilder.allowOutOfTransactionUpdateOperations(boolean), Constant Field Values
  - AUTO_CLOSE_SESSION
```
static final String AUTO_CLOSE_SESSION
```
    When enabled, specifies that the Session should be closed automatically at the end of each transaction.
    
    See Also:
    
    SessionFactoryBuilder.applyAutoClosing(boolean), Constant Field Values
    
    Default Value:
    
    false
  - FLUSH_BEFORE_COMPLETION
```
static final String FLUSH_BEFORE_COMPLETION
```
    When enabled, specifies that automatic flushing should occur during the JTA Synchronization.beforeCompletion() callback.
    
    See Also:
    
    SessionFactoryBuilder.applyAutoFlushing(boolean), Constant Field Values
    
    Default Value:
    
    true unless using JPA bootstrap
