trc recreation

the trail is complete, I will see the trail file in this directory, however, when I open it, I find that there are many trace files in it, and I don't know which file I used, so next, I will return to SQL * Plus to query the process ID of the session where the trail is executed, because the file name format of the trail file is (instance name_ora _ process ID. TRC), My Instance name is orcl, so I run the query to determine the process ID. Before the

α = 0.05 2. Calculate the theoretical number (TRC). The formula is as follows: TRC = Nr. nc/n formula (20.13) In the formula, TRC indicates the theoretical number of the lattice in Column C of row R. Nr indicates the Union count of the theoretical number, NC indicates the Union count of the column with the theoretical number, and N indicates the total nu

alive, the process will not execute the close () function on the trace file. The process still holds the file descriptor pointing to the trace file. The trace file name includes the pid of the process, Therefore, unless the process is restarted, we cannot disable file descriptor or create a new file with a new or old file name. This does not mean that in an emergency, you cannot access this trace file. After the trace file is deleted, as long as the file descriptor is still open, you can get
