Hi everyone, I have two problem about prime infrastructure. The fisrt one is what's file about "ts_sam_def.dbf",this file we can show it under shell mode (root mode before PI3.x) by "du -h --max-depth=1 /opt/oracle/base/oradata/WCS/datafile/*" command.The file is so large,so whether we can delete it? The second one is i want to add disk for PI in vsphere,whether there will be a detial steps about that? I can find this blog: {Tuesday, January 15, 2013 Increasing diskspace on Cisco Prime Infrastructure NCS 1.2 "the hard way?"} but i cannot fixed it step by step. If you have a better workaround,pelase help me to fixed it. Thanks & BR.

 - Don't delete database files manually from Prime, because then it will become corrupt ; you may use to shorten data retention and or use 'ncs cleanup' to remove old data. (Google on those terms for more info). For adding disk space ; check this article :
