5 Database Administration Database Interface Process

UCS 1000 R4.2 Administration 585-313-507 Issue 3 April 2000 216

~ 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:

× 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

1 2 ... 250 251 252 253 254 255 256 257 258 259 260 ... 744 745
