RWSY FN: SYNCxxx [TYPE:x]—Source TCP SYNC/RESYNC Trace Point

 

This source-side trace point records various commands and replies flown in the execution of TCP/IP two-phase commit operations.

The segment of the data represented by the preceding 'xxx' can be:

• CTL, representing a control command

• RSY, representing a resync command

• CRD, representing reply data from a control command

• RRD, representing reply data from a resync command

For the CTL and RSY records, there is also a TYPE code associated with the commands. It is not a printable character, so it is observable only in the hexadecimal data part of the record. It follows the string 'TYPE:'.
