Transaction Inventory Page
Page Type 3 is a transaction information page (TIP). The TIP header includes the address of the next TIP.
The body of a TIP is an array of pairs of bits that reflect the state of transactions. If both bits are 0, the transaction is active or has not started. If both bits are 1, the transaction is committed. If the first bit is 1 and the second bit is 0, the transaction rolled back. If the first bit is 0 and the second is 1, the transaction is in limbo.
Limbo is the state of a two phase transaction that has completed the first phase, but not the second.
