RU parameter coding

RU means count all request/response unit codes.

RU(NC(...)), RU(SC(...)), RU(DFC(...)), RU(FMD(...)), or RU(AMRU(...)) means count only the RUs in categories which have the specified codes as follows:
  • NC, SC, and DFC codes are 1 or 2 bytes 1:
    • SNA codes are 1 byte.
    • AMRU codes are 2 bytes. The first byte is X'FF'.
  • FMD codes are 3 or 4 bytes 1:
    • SNA codes are 3 bytes.
    • AMRU codes are 4 bytes. The third byte is X'FF'.

You must fully specify all codes (the VIT analysis tool does not pad codes).

RU(...) means process only the RUs with those codes. Each code is 1, 2, 3, or 4 bytes. The VIT Analysis Tool counts these codes in any and all categories. For example, X'0D' is the NC code for NC-ACTVR and the SC code for ACTLU. If you specify RU(0D), the VIT analysis tool will count both of these RU codes.

You can specify up to:
  • 32 codes for RU(NC(...)),
  • 32 codes for RU(SC(...)),
  • 32 codes for RU(DFC(...)),
  • 32 codes for RU(FMD(...)),
  • 32 codes for RU(AMRU(...)), and
  • 32 codes for RU(...).
You can specify the RU codes individually or in lists. For example,
    RU(SC)31,32,FF31,FF32))
is equivalent to
    RU(SC(31)) RU(SC(32)) RU(SC(FF31)) RU(SC(FF32))

RU(REQ) means process requests. RU(RESP) means process responses. By default (if you specify neither RU(REQ) nor RU(RESP)), the VIT analysis tool counts both requests and responses.

RU(FROM(...)) means count RUs flowing from the specified network address to any network address. RU(TO(...)) means count RUs flowing to the specified network address from any network address. RU(FROMTO(...)) means count RUs flowing from the first network address to the second network address. You can specify up to:
  • 24 RU(FROM(...)) options
  • 24 RU(TO(...)) options
  • 24 RU(FROMTO(...)) options
Each subarea field (subarea_number) is exactly 4 bytes 1. Each element field (element_number) is exactly 2 bytes. The element fields are optional. For the RU(FROMTO(...)) option, if you omit the first element address, keep its comma as a place-holder.
Note: You must specify the RU(FROM(...)), RU(TO(...)), and RU(FROMTO(...)) options individually. (You cannot combine them in lists like RU codes.)

By default [if you specify neither RU(FROM(...)), RU(TO(...)), nor RU(FROMTO(...))], the VIT analysis tool ignores the origin and destination fields in the PIUs.

RU(SORT(NAME)) means sort the request and response counts by RU name (the default). RU(SORT(FREQ)) means sort the counts by frequency (highest count first).

1 Two hexadecimal digits represent 1 byte. For example, X'FF' is 1 byte. For RU counting, you must specify all hexadecimal digits and you must omit the X and quotation marks. For example, RU(NC(X'C')) is not valid; RU(NC(0C)) is valid.
