Tracking exp with 10046 AND exp with 10046
I wrote a blog about why Oracle expdp is faster than exp. What is the principle? I learned from the official documentation. Now I am going to analyze the exp process through 10046.
C: \ Users \ Administrator> exp LCAMTEST/LCAMTEST@10.10.15.25 _ LCAM file = d:/test. dmp tables = (BPMS_RU_ACTIVE_INS)
SQL> SELECT p. spid, p. addr, p. pid, s. sid, SUBSTR (s. username, 1, 15) "USERNAME ",
SUBSTR (s. program, 1, 15) "PROGRAM"
FROM v $ process p, v $ session s
WHERE s. paddr = p. addr
AND addr = (SELECT paddr FROM v $ session where upper (program) LIKE 'exp % ');
SPID ADDR PID SID USERNAME PROGRAM
