Hi, Expdp is slow in the following environment. OS:uname -a SunOS 5.10 Generic_142900-01 sun4v sparc SUNW,T5140 Oracle version: 10.2.0.5 For 200MB,it takes more than one hour. I observed that expdp takes some time in estimating operation.. Used script for expdp: expdp test\*** \ DIRECTORY=dmp_dir \ DUMPFILE=$EXP_FILE \ LOGFILE=expdp.log \ SCHEMAS=test But export(exp) is much faster in the same environment.Please let me know is there any know behavior/issue. Regards Krishna
