The System Properties, Threads, and CWMS_HOME Directory tabs from the Options dialog (Figure 1), pertain to settings that deal with the CWMS software. From some of these tabs you can make changes, it is recommended that you only use this information from these tabs for debugging and viewing purposes. If you make changes to system properties, any changes made are not persistent and are not saved permanently.

System Properties Tab

The System Properties tab (Figure 1) allows you to view the system properties values set for the CWMS software. If you have the correct user access, you can edit some or all of these properties. The recommendation is that you only use this information for debugging and viewing purposes. Editing must be done with extreme caution as any changes you make can directly affect the CWMS functionality.

Threads Tab

A thread is a single sequential flow of control within software. Within Java the user has the ability to have multiple threads in a piece of software all running at the same time and performing different tasks. CWMS is a multi-threaded software application, to view CWMS threads, from the Options, click the Threads tab (Figure 6). The Threads tab displays information regarding the threads that are actively being used by CWMS. To provide an up-to-date list of the active threads, click Refresh (Figure 6).

CWMS_Home Directory Tab

The CWMS_HOME Directory tab (Figure 7) pertains to two CWMS system variables – CWMS_HOME and CWMS_EXE. In most cases, the normal user will not be doing anything to these two system variables. If you are dealing with client-side scripts, the tab provides an interface for overriding the values of CWMS_HOME and CWMS_EXE.

Figure 7 Options Dialog - CWMS_HOME Directory Tab

Local CWMS_HOME

To edit the CWMS_HOME variable, select Override local CWMS_HOME directory environment setting (Figure 7). The Local CWMS_HOME box is now active. CWMS_HOME only needs to be overridden if client-side scripts rely on CWMS_HOME as a pointer to where data and models reside on the client file-system. For example, CWMS_HOME might be set to a "watershed location", following a common convention to keep gridded DSS records in the "database" folder that is sister to a folder containing the watersheds.

Local CWMS_EXE

You should only need to override CWMS_EXE if client-side scripts rely on CWMS_EXE to locate CWMS executables or .jar files. If you need to override *CWMS_EXE, from the Local CWMS_EXE box (Figure 7) enter the new value.

Archive Tab

You can archive a forecast, the archive is posted to the selected watershed's default directory as a .zip file. If you wish to override the default directory and or the name of the archive, from the *Options dialog, click the Archive tab (Figure 8). 

  1. If you want to change the location of where the archive file is saved, you can enter a folder name in the Default Archive Folder box (Figure 8). another way to get a folder name, to the right of the Default Archive Folder box (Figure 8), click , an Open browser will open. Navigate to the location where you want archives saved, once the name displays, click Open. The Open browser will close, and name will display in the Default Archive Folder box (Figure 8).
