Member Function Documentation
| int drizzled::plugin::XaResourceManager::commitOrRollbackXID | ( | XID * | xid, |
| bool | commit | ||
| ) | [static] |
The below static class methods wrap the interaction of the vector of registered XA storage engines.
Definition at line 46 of file xa_resource_manager.cc.
| virtual int drizzled::plugin::XaResourceManager::doXaCommit | ( | Session * | session, |
| bool | normal_transaction | ||
| ) | [private, pure virtual] |
Does the COMMIT stage of the two-phase commit.
| virtual int drizzled::plugin::XaResourceManager::doXaCommitXid | ( | XID * | xid | ) | [private, pure virtual] |
Commits a transaction identified by a XID.
| virtual int drizzled::plugin::XaResourceManager::doXaPrepare | ( | Session * | session, |
| bool | normal_transaction | ||
| ) | [private, pure virtual] |
Does the PREPARE stage of the two-phase commit.
| virtual int drizzled::plugin::XaResourceManager::doXaRecover | ( | XID * | append_to, |
| size_t | len | ||
| ) | [private, pure virtual] |
Notifies the transaction manager of any transactions which had been marked prepared but not committed at crash time or that have been heurtistically completed by the storage engine.
- Parameters:
-
[out] Reference to a vector of XIDs to add to
- Return values:
-
Returns the number of transactions left to recover for this engine.
| virtual int drizzled::plugin::XaResourceManager::doXaRollback | ( | Session * | session, |
| bool | normal_transaction | ||
| ) | [private, pure virtual] |
Does the ROLLBACK stage of the two-phase commit.
| virtual int drizzled::plugin::XaResourceManager::doXaRollbackXid | ( | XID * | xid | ) | [private, pure virtual] |
Rolls back a transaction identified by a XID.
