(Back to the Previous Post in the Series) (Forward to the Next Post in the Series)
In the previous blog article in this series, we examined the output generated by one of my programs. Most of that output was centered on the analysis of the time model statistics in Oracle Database 10.1 and above. The intention of this blog article series is to try to build a similar tool using nothing more than Microsoft Excel. I do not know yet if it is possible, but we will definitely try to make it work. Unfortunately, there are a couple of features missing in Oracle Database 10.1 as well as some of the statistics being named differently from later release versions of Oracle Database, so this project will target Oracle Database 10.2.0.1 and above. This project will use a Microsoft TreeView control which might not be installed on your computer, however I verified on a Windows 7 32 bit computer with Excel 2010 installed, that if you are able to find the OCX file containing the Treeview and register that file with Windows, it can be used in the Excel development environment for this project.
If you attempted the project in the previous article of this series (that project is the starting point for today’s article), you may have received an odd error message when opening the project (at least I did on Excel 2007). The message is “Can’t execute code in break mode” – if you received that error message, there is a simple fix – just hit the F5 key on the keyboard to tell Excel to continue executing the code. The reason why this error message appears is likely related to the ShowModal property of the UserForm. When that property is set to True (apparently the default), that UserForm has the full attention of Microsoft Excel until it is closed – that of course causes problems when the worksheet opens and the form displays automatically. There are two methods to work around this issue, the first requires changing the following line in the code:
frmTimeModel.Show
to this:
frmTimeModel.Show vbModeless
In my opinion, the above is a little ugly, so let’s instead change the ShowModal property of the UserForm. View the code in the worksheet (see the directions found in the previous article), double-click frmTimeModel under the Forms heading (below Microsoft Excel Objects that was used in the previous article), click once on the background of the UserForm, and then in the Properties window, change the ShowModal property from True to False (don’t ask me why the constant is spelled differently than the property, someone was just being creative I guess):
Now double-click the UserForm’s background area – that will display the programming code that is related to what we double-clicked (the UserForm in this case). So far, only the following code should appear in the UserForm’s code – this is what causes the TimerEvent procedure to start executing once a second when the UserForm is first displayed on the screen:
Private Sub UserForm_Initialize()
TimerEvent
End Sub
Move the cursor in front of “P” in the word Private and hit the Enter key a couple of times to insert a couple of blank lines. We will need to copy in a lot of code into that blank area – some of the code will not be used immediately, but we will need it later. Add the following code above the word Private – these are all of the variables that are needed throughout our UserForm:

Now change the UserForm_Initialize procedure so that it shows the following:
Private Sub UserForm_Initialize()
Dim intResult As Integer
Dim strUsername As String
Dim strPassword As String
Dim strDatabase As String
Dim strSQL As String
On Error Resume Next
'Database configuration
strUsername = "MyUsername"
strPassword = "MyPassword"
strDatabase = "MyDB"
Set dbDatabase = New ADODB.Connection
dbDatabase.ConnectionString = "Provider=OraOLEDB.Oracle;Data Source=" & strDatabase _
& ";User ID=" & strUsername & ";Password=" & strPassword & ";ChunkSize=1000;FetchSize=100;"
dbDatabase.ConnectionTimeout = 40
dbDatabase.CursorLocation = adUseClient
dbDatabase.Open
If (dbDatabase.State <> 1) Or (Err <> 0) Then
intResult = MsgBox("Could not connect to the database. Check your user name and password." & vbCrLf & Error(Err), 16, "Charles Hooper's Oracle Database Time Model Viewer")
Exit Sub
End If
'More code will be copied here
'
'
'
TimerEvent
End Sub
At this point, after replacing MyUsername, MyPassword, and MyDB (the DB name from the tnsnames.ora file) with the appropriate logon credentials for one of your databases, you should be able to verify that the database connection works by running the UserForm_Initialize subroutine, simply by pressing the F5 key on the keyboard. If no error message appears on the screen, the macro is able to connect to the database. Now that we have verified that database connectivity works as expected, let’s close the UserForm’s window and add a little more code to the UserForm_Initialize subroutine. Move the cursor just above the ‘More code will be copied here line and press the Enter key a couple of times to move that line down a little. Move the cursor back up to one of the blank lines and paste in the following code which sets up a couple of the SQL statements that will be used by this tool:
lngTimerTriggerSeconds = 60
sglSessionMinimumPercent = 0.1 '10% of the total for the time period needed to be included in the detail

We will add more later, but that is sufficient for a starting point. Just below the End Sub in the UserForm_Initialize procedure, add the following code, which will perform clean up when the UserForm is closed:
Private Sub UserForm_Terminate()
intKillFlag = True
If dbDatabase.State = 1 Then
dbDatabase.Close
End If

Set comDataWait = Nothing

Let’s switch back to the design of the UserForm (if you cannot see the UserForm’s window, right-click frmTimeModel below Microsoft Excel Objects and select View Object from the menu), where we will add a couple of labels to the form. This will be a little time consuming, but if you create one of the white box labels and a heading label, you can copy and paste the two labels as many times as is necessary (hold down the shift key to select more than one label to copy). We will need a total of 11 labels with BackColor property set to &H00FFFFFF& (white) and with the BorderStyle property set to 1 – fmBorderStyleSingle and with the TextAlign property set to 3 – fmTextAlignRight – we will also need a total of 11 plain labels with the TextAlign property set to 2 – fmTextAlignCenter.
Set the (Name) property of the white background labels using the following list (one name per label): lblCPUs, lblBusyTime, lblIdleTime, lblBusyPercent, lblUserMode, lblKernelMode, lblUserModePercent, lblCPUUsedBySession, lblParseTimeCPU, lblRecursiveCPUUsage, lblOtherCPU
For the 11 plain labels with the centered text, change the Caption property of those labels to identify the contents (such as CPUs, Busy Time, etc.) of the closest white background label. When the additions are complete, your UserForm might look something like the picture below:
Now we need to switch back to the code for the frmTimeModel UserForm and add a little more code to actually query the database. Scroll up toward the top of the code in the UserForm, and locate this line:
Dim intExcludeIdleWaits As Integer 'Indicates whether or not to exclude idle wait events
Move the cursor to the end of that line and press the Enter key a couple of times to add a couple of blank lines. On one of the new blank lines paste the following code, which will query the database when executed:
Public Sub ReadData()
Dim i As Integer
Dim j As Integer
Dim k As Integer
Dim strSQL As String

We are almost ready to take the code for a test drive. First, we need to make a couple of changes to the code in the TimerEvent subroutine. That subroutine is found in Module1 under the Modules heading (which is below the Microsoft Excel Objects heading). Double-click Module1 to display the code in that module. Change the TimerEvent subroutine to look like this:
Public Sub TimerEvent()
lngTimerEventCounter = lngTimerEventCounter + 1
If intKillFlag = False Then
If lngTimerTriggerSeconds <= lngTimerEventCounter Then
lngTimerEventCounter = 0
frmTimeModel.ReadData
frmTimeModel.UpdateDisplay
End If
'Instruct Excel to execute the TimerEvent sub again in 1 second
Application.OnTime DateAdd("s", 1, Now), "TimerEvent"
End If
End Sub
The above code tells Excel to execute the ReadData subroutine and then the UpdateData subroutine every time the number of elapsed seconds is equal to the value specified by the lngTimerTriggerSeconds variable, which is set to 60 by default in the code.
Save the Excel workbook, close the workbook, and then open the workbook again. If everything works right, after about 60 seconds you should see the time model statistics for the previous 60 seconds, something like this:
Wow, that is a lot of code for what little is shown in the above screen capture. We will continue from here in the next segment of the series.
