Well, OK, so I'm totally willing to work with you to help get this
straightened out, but I'm not really going to go download orafce and
debug it for you on company time. I'm fairly sure that won't win me
any large awards.I'll do it - just need to finish some other. I hope so this night I'll know more.
In _PG_init I am creating new tranche by RequestNamedLWLockTranche("orafce", 1);
Immediately when I try to use this lock
shmem_lock = sh_mem->shmem_lock = &(GetNamedLWLockTranche("orafce"))->lock;
shmem_lock = sh_mem->shmem_lock = &(GetNamedLWLockTranche("orafce"))->lock;
I got a error
ERROR: XX000: requested tranche is not registered
LOCATION: GetNamedLWLockTranche, lwlock.c:602
ERROR: XX000: requested tranche is not registered
LOCATION: GetNamedLWLockTranche, lwlock.c:602
Because the session initialization doesn't finish, then Orafce doesn't work
