The VHS Log screen presents information collected by a VHS process.
VHS, or the Virtual Hometerm Subsystem, provides a stable location for processes to log message usually related to a problem or status update. Messages received by VHS are logged to a file which may be viewed on this screen. If the screen is going forward in time and reaches the end of file, new messages are automatically displayed shortly after they are written. However, if VHS switches to a new log file, the screen will stop displaying new messages. The user must manually select a new log file in order to continue viewing new messages.
The log file used by VHS does not have a unique file code assigned by default, so It is necessary to logon to MOMI and have the necessary security to view a VHS Log.
To start viewing VHS Log files, press the Config button and Specify a log file. To aid in selecting a log file, press the locator button to display the File Locator pop-up window. Unfortunately, MOMI cannot automatically determine the active LogFile as VHS does not provide such a mechanism. However, using the File Locator, usually the file with the highest sequence number, or LOG0001 in the image below, is the current file.
A default location where the File Locator drills-down to may be set with the CONFMOMI keyword SELECTION-DEFAULT-VHS. This keyword provides two functions. First, the File Locator automatically drills down to the subvolume specified (the File Locator may display files other than VHS log files). Second, the special name of "CURRENT VHS LOG FILE" appears and will automatically select the current VHS Log file based on modification date. The automatic selection only occurs when Request is pressed.
After selecting the log file, press Request. Use the scroll bar to move forward and backward in time through the file.
