Tandem Capacity Model (TCM) Manual

NOTE: You can use a Transaction Count file instead of a Transaction Count table to count
transactions processed by your application. For information on the Transaction Count file, see the
subsection “Transaction Count Table Versus Transaction Count File” (page 120).
If you are using a Transaction Count file, each entry in the Transaction Count table can be zero
(0).
1. Open a WA model.
2. Log on as an administrator or super user. For more information about this step, see “Changing
Authorization Levels” (page 69).
3. Select Find > Transaction Count Table. If this option is unavailable, select Options > Calculate
Now to update the table. Then select Transaction Count Table under the Find tab again. The
Transaction Count table appears. Figure 17 (page 78) shows a default Transaction Count
table.

4. Select Options > Unprotect Admin Fields to unprotect the Transaction Count Table so you can
change its entries. (They are normally protected against modification.)
5. Change the entries in the Transaction Count table to best reflect your application’s
characteristics.
6. When you finish, select Options > Protect Admin Fields to protect the apportionment tables.
Although this step is optional, it is good practice. It safeguards your data from unintentional
corruption.
7. Select Options > Calculate Now to update the table.
8. If you want to save your modifications to the file, select Save or Save As under the File tab.
See “Saving the Tables” (page 78) in the next section.
Saving the Tables
If you do not save the apportionment tables, they are automatically saved when you save the entire
model. However, it is recommended that you save the tables as soon as they are created.
To save the tables:
