RFUTIL ROLL FORWARD RETRY Qualifier

Enhances the support of 24 X 7 database operations. The use of this qualifier is limited to RFUTIL roll-forward operations that fail because of power outages or system failures. The ROLL FORWARD RETRY qualifier restarts the roll-forward operation on the after-image extent that was in the process of rolling forward. The retry operation finds the transaction in process at the time of failure and resumes rolling forward. It recovers the (transaction log) TL extents. Entries noting the use of the retry operation appear in the LG file of the database. If subsequent failures occur during the retry operation, the retry operation can be restarted.

db-name

Specifies the database you are using.

endtime

Specifies to roll forward to a certain point in time. You must specify the ending time as a string of digits and separate the date and time components with a colon. Transactions are included in the partial roll forward only if they end before the specified time. For example, to roll forward to 5:10 PM on July 18, 2002, type 2002:07:18:17:10:00. For Progress to include a transaction in this partial roll forward, the transaction must have ended on or before 2002:07:18:17:09:59.

endtrans

Specifies to roll forward up to but not including the transaction beginning that contains the transaction-number. For example, if you specify endtrans 1000, Progress rolls forward the AI area to transaction 999. If you want to include transaction 1000, you must specify endtrans 1001.

-B n

Specifies the number of database buffers. The single-user default value is 20.

-r

Directs Progress to use buffered I/O.

verbose

Produces one line of information for every note in the AI area.

-a ai-area

Identifies the AI area of the specified database.
