I was looking at db/dbCaTest.c today, and I found that dbcar() is looping through all record instances of all types, and taking dbLockSetGblLock() when investigating a CA link. dbcaStats() is looping through all record instances of all types, and NOT taking dbLockSetGblLock() when investigating a CA link. Why? Why not? dbcar() is doing more CA investigation, and using the formatter in-between. But other than that, dbcaStats() could also encounter another thread changing the link type from CA to DB or CONSTANT. Can anyone explain why these similar cases are handled differently? Thanks a lot! Clueless, ~Ralph |
