IMS protected memory requirements:
APP_SIZE_TBL = 10
MSG_SIZE_TBL = 20
LTN_TN_TBL = 255
LTN_LINK_TBL = 65
Note 16
If New Flexible Code Restriction (NFCR) is chosen for a customer, the
following memory requirements are also needed:
• A 129 word block that contains:
— A 128 word table containing the pointers to the FRL block for each
route
— A pointer to the tree root address table
• A table that contains the pointers to the NFCR trees. Its length will be
defined by the maximum number of trees (defined in the customer data
block)
• Four words will be required for each route that has defined FRL codes
• Storage for customer defined trees. Amount of memory used depends on
the size of code restriction trees the customer has defined.
It is possible to calculate an upper bound for the amount of memory that a tree
is using by applying the following:
• The INIT condition occupies 14 words
• For each digit sequence after the INIT condition:
— if the digit sequence is greater than 1 digit, then memory required for
digit sequence increases by 1.
— if the digit sequence has a count field, then memory required for
digit sequence increases by 1.
— if the digit sequence is from a BYPS, then memory required for digit
sequence increases by 1.
