The number of blocks in the log file. This value is also specified when running IIBUILD or rcpconfig. Multiply by the block size to get the log file size in bytes.

The log file block size in bytes. This value is specified when running the install or configure program.

The number of log buffers. These are the same size as the log file block size.

The logging system parameter LOG_FULL_LIMIT occurs. When the Blocks in use field is equal to this value, all transaction activity is halted. A warning field is displayed in the lower right-hand corner. This value is also determined when running the install or configure program. For more information see, the System Administrator Guide.

The logging system parameter FORCE_ABORT. When the Blocks in use field exceeds this value, the oldest transaction is aborted. To find out which transaction is being aborted, use the Log Transaction Display screen. Also, see Logging System Header Screen with Transaction Display. Tab to the Status column and select the Find menu item to look for the word FORCE. A warning indicator is also displayed. For more information, see the System Administrator Guide.

A consistency point occurs when the log file size (Blocks in use field) reaches a multiple of this number.

The number of blocks in use in the log file. This is determined by the Begin (BOF) and End (EOF) values. This value is used for the Log file in use diagram.

The number of remaining blocks in the log file

The number of blocks set aside to write compensation records in the event that transactions need to rollback.

The logical beginning of file. This is the position in the log file that holds the oldest transaction.

The logical end of file. This is the position in the log file that holds the newest uncommitted transaction.

The log file address of the last consistency point. This is the position in the log file where the last consistency point was taken.

The log file address of the next expected consistency point

The status of the logging and recovery systems. For a list of valid status fields, see Logging System Header Screen—Status Field Values.

Depicts a logical view of the log file with the left side of the field representing page 1 and the right side representing Block count pages (for example, 1024 pages). Within this field an arrow diagram (">------>") represents the portion of the log file in use. If the portion of the log file in use spans only one position in the field, an "*" is displayed. As the EOF and BOF change, the arrow moves from left to right and wrap around the diagram.

The percentage of the log file in use. This is determined by the Begin (BOF) and End (EOF) values.
