Micro-PWC OPERATOR’S MANUAL

• the node name
• the size of the disk space allocated for the database in KB
• the number of KB of the allocated space actually used (and the percentage)
• the total number of KB available on the node’s hard drives
Archival data is keyed (internally) by time within the Archival Database, so the Time Section radio button
(below the list box containing disk usage information) should be selected. (See the Micro-PWC
Configuration Guide for a more detailed discussion of the Time Section and String Section radio
buttons.) This will cause the tagname of every Archival Database point in every Archival Database in the
console group (not just the local node) to be listed alphabetically in the tagname list box. The information
displayed includes:
• the tagname preceded by an s
• the node or nodes where the point is part of the Archival Database
• the percentage of the node’s Archival Database used to store that point
The Archival Database Maintenance window also contains the following buttons: Close, Delete, Prev,
Next, Find, and Clear Database.
11.3.2.1.1 Locating Specific Archival Tags
If more Archival Database points have been configured than can appear in the Archival Tag list box, the
Prev and Next buttons will become available. Click Next to display the Archival tags which follow those
currently on display in the list box. Click Prev to display the Archival tags which precede those currently on
display in the list box.
The Find button (at the bottom of the Archival Database Maintenance window) can be used to determine
the presence of a given point in the Archival Database. If the point does exist, Find quickly locates it in the
Archival Tag list box, and highlights it.
To use this feature, click Find. A window appears, which contains an entry box, and OK, Apply and
Cancel. Select the entry box and then enter the desired archival tagname. If only a portion of the tagname
is entered, the first entry where the first letters of the tagname match the entered string will be chosen. For
example, if the string HR is entered, and the first tagname to begin with these characters is HRAN01, then
this is the tagname that would be highlighted in the Archival Tag list box.
Click Apply to locate the first instance of the string; the Find window will remain open. Click Apply again to
locate the next instance of the string, or enter a new string to be located. Click OK to perform the Find
operation and close the Find window. Click Cancel to exit without attempting to find the tagname in ques-
tion, or to close the window.
11.3.2.1.2 Deleting Archival Data
To delete all data for a point from the Archival Database on all nodes, click the tagname to select it, then
click the Delete button. All data for that point in the local node’s Archival Database will be deleted. The
space allocated for the point will not be released.
To delete all data from the Archival Database on all nodes in the console group, and release the space
allocated for it, click on the Clear Database button. A confirmation window will ask:
Database will be cleared.
Are you sure?
To abort the operation, click No. To delete all the archival data stored on all nodes, click Yes. The data will
be deleted, the disk space will be deallocated, and the window will close.
