ARIES/RL: An Extension of ARIES with Re-Logging to Support Long-Duration Transactions
Jae-Mok Jeong, Kang‐Woo Lee, Hyoung-Joo Kim · 2000
We propose the ARIES/RL which extends the with 're-logging' technique to manage the limited online 1og space efficiently even though 1ong-duration transactions exist. Re-logging isa technique that log records used in transaction rollback and restart recovery are copied forward in the log whenever the online log is not sufficient for keeping logs of on-going transactions It does not hurt the advantages of ARIES. Moreover, it handles log space efficiently in executing long-duration transactions. We also present the evaluation result of ARIES/RL and show that ARIES/RL handles online log efficiently.
