This subsection explains the SQC extended log file.
The SQC extended log file is created automatically by the SQC Extended Log Collection when the SQC extended logs are accumulated.
Storage location
The SQC extended log file is stored in the following directory.
[Windows]
<Variable file storage directory>\extend-log\ |
[UNIX]
/var/opt/FJSVssqc/extend-log/ |
File namae format
The SQC extended log file name has the following format. A new file name is created each time the SQC extended log file is switched. The characters shown in blue indicate variables.
logyyyymmdd_nn
[Explanation of variable characters]
Symbol | Meaning |
|---|---|
yyyy | Year of creation date (1970 to n) |
mm | Month of creation date (01 to 12) |
dd | Day of creation date (01 to 31) |
nn | Serial number of the SQC extended log file among those log files created on the same day (01 to 99) |
The formula for estimating the capacity per day is as follows. The characters shown in blue indicate variables.
(Capacity per day) = (50 + A + B) * C
Symbol | Meaning |
|---|---|
A | Average number of bytes of the client field |
B | Average number of bytes of the document field |
C | Average access count to the document per day |
To simplify work such as backup of the SQC extended log file, the SQC Extended Log Collection periodically creates a new SQC extended log file (file name logyyyymmdd_nn as described in 15.2.5.1) to change the accumulation destination of the SQC extended log to the new log file. This operation is referred to as "SQC extended log file switching."
SQC extended log file switching is performed in accordance with the settings in the Extended Log Environment Definition File "ExtendLogConfig".
For details on how to set the Extended Log Environment Definition File, refer to "15.2.2 Extended Log Environment Definition File".
