~ read = the number of read table operations performed on different
tables by applications (per channel)
~ cursor = the number of cursors involved in the read table
Note: Multiple reads of the same table use only one cursor.
The following are sample calculations using various configurations and
numbers of read table operations.
• If you have a 24-channel system running an application that performs four
read table operations on four different tables per channel, the calculation
is:
24
× 4 × 1 = 96
Since 96 is less than 500, the database operations proceed properly.
• If you have a 36-channel system running an application that performs four
read table operations on a single table per channel, the calculation is:
36 × 1 × 1 = 36
Since 36 is less than 500, the database operations proceed properly.
• If you have a 48-channel system running an application with five read
table operations on five different tables per channel, the calculation is:
48 × 5 × 1 = 240
