3.4.2 Estimating the size of the trace log file

This subsection explains how to estimate the size of the trace log file. The trace log file is set as follows in the initial status.

• Storage location

  For Windows Server 2012 or Windows Server 2008, if the installation folder is in the default folder or a folder protected by the system:

  %ALLUSERSPROFILE%\Hitachi\JP1\JP1_DEFAULT\JP1AJS2\log\tracelog

  The default %ALLUSERSPROFILE% value is system-drive\ProgramData.

  A folder protected by the system is the path to a folder in any of the following:

  - system-drive\Windows

  - system-drive\Program Files

  - system-drive\Program Files (x86) (for 64-bit Windows)

  For Windows Server 2012 or Windows Server 2008 in which an installation folder other than the above is used:

  JP1/AJS3-installation-folder\log\tracelog

  In Windows Server 2003:

  JP1/AJS3-installation-folder\log\tracelog

  In UNIX:

  /var/opt/jp1ajs2/log/tracelog

• Size

  A size that can accommodate the trace log from the execution of approximately 2,000 jobs (specifically, 20 megabytes (20,480 kilobytes))

The required trace log file size differs greatly depending on the jobnet structure, the number of JP1/AJS3 - View connections, and the nature of the operations. Estimate an appropriate size for the trace log file and expand the current size if necessary.

The formula for calculating the size of the trace log file is as follows:

Appropriate trace log file capacity (units: kilobytes) = 3,072 x (number-of-jobs-executed-per-day / 500 + number-of-AJS3-operations^#1-executed-per-day /1,000) x number-of-scheduler-services x 1.5 x number-of-days-to-save-trace-logs^#2

#1

Refers to operations performed on units by commands or from JP1/AJS3 - View.

#2

Specify the number of days from the occurrence of the error to the collection of data.

Example: Saving the trace log for one day (only for a physical host with one scheduler service)

• 3,000 jobs are executed per day.

• 500 hold-release and other commands are executed per day.

  Appropriate trace log file capacity = 3,072 x (3,000 / 500 + 500 / 1,000) x 1 x 1.5 x 1 = 29,952 kilobytes
