Configuring ECC Variables for Use by CTI Server
Before entering ECC variables using the configuration tool, the total size of the ECC variables
must be validated against the following rules and limits.
must be validated against the following rules and limits.
Step 1
Since the total size of the buffer used to store the variables in CTI Server internally is 2500
bytes, the total sum of all the maximum buffer sizes for each scalar variable and arrays must be
no greater than 2500.
bytes, the total sum of all the maximum buffer sizes for each scalar variable and arrays must be
no greater than 2500.
Step 2
The maximum buffer size for each scalar variable = 4 + length of the ECC name + the maximum
length of the variable where the 4 bytes includes a 1 byte tag, 1 byte to define the length, and
2 terminating NULL characters.
length of the variable where the 4 bytes includes a 1 byte tag, 1 byte to define the length, and
2 terminating NULL characters.
Step 3
The maximum buffer size for each array = (5 + length of the ECC name + the maximum length
of array element) * (the maximum number of elements in the array) where the 5 bytes includes
a 1 byte tag, 1 byte to define the length, 1 byte for the array index, and 2 terminating NULL
characters.
of array element) * (the maximum number of elements in the array) where the 5 bytes includes
a 1 byte tag, 1 byte to define the length, 1 byte for the array index, and 2 terminating NULL
characters.
For example, if you intended to use one scalar ECC variable with a maximum length of 100
bytes named user.var, one scalar ECC variable with a maximum length of 80 bytes named
user.vartwo, and an ECC array named user.varthree with a maximum of 9 elements with each
element having a maximum length of 200 bytes, the buffer size would be:
bytes named user.var, one scalar ECC variable with a maximum length of 80 bytes named
user.vartwo, and an ECC array named user.varthree with a maximum of 9 elements with each
element having a maximum length of 200 bytes, the buffer size would be:
(4+8+100) + (4+11+80) + ((5 + 13 + 200)*9)) = 2169
where 8 is the length of user.var, 11 is the length of user.vartwo and 13 is the length of
user.varthree.
user.varthree.
User Variables
You can also create global user variables; for example, you could create a user variable called
usertemp to serve as a temporary storage area for a string value used by an If node.
