  My only concern is the result of this sql. East - reliable? It can really be used to differentiate the two lines? I mean, the result would be the same, as I do with Java?

  Not sure what you mean by "reliable"? SQL is not some kind of generator of random result (by derogation from the use of the DBMS_RANDOM package). If you ask him if 1 + 1 = 2, then it will always give you the right answer.

• How to compare premises, iSCSI and storage NFS for VMware ESXi 5 with IO Analyzer?

  Hello

  I have 2 hosts ESXi 5.0 with a few virtual machines running. I would compare the IO throughput for my local storage, iSCSI and NFS vmware storage store. Can someone point me to the right direction? I read the documents and tutorials, but I'm not sure how to compare tests from these 3 options.

  I have a need to compare the following storage options.

  Local disk on the ESX host

  iSCSI on QNAP NAS device

  iSCSI on EMC e 3100

  NFS on QNAP NAS device

  NFS on EMC e 3100

  IOmeter seems to be good tool based on reading, but still not clear where to make changes to pass tests of storage to another.

  Thanks in advance,

  Sam

  If you use IO monitor, then you must simply vmotion the VMS to the data store for the device you want to test, and then run the test (and Records results).  Can vmotion for the following data store and repeat.

• How to compare two users (2)

  Hi all

  11.2.0.1

  AIX 6.1

  I have two databases (dev & uat) on separate servers with equal facility.

  On each database, I created a schema user "batchdba" and gave them same privilege "dba".

  But when I import (impdp) the dumpfile output from other databases that encrypted table and with the same command, it runs successfully on DEV but not on the UAT.

  How can I compare that privilege is missing from the UAT for the user "batchdba". Or how to compare the privileges granted to these two patterns?

  Thank you very much

  zxy

  You can query the following views on the databases to compare the result

  dba_tab_privs

  dba_role_privs

  dba_sys_privs

  query these tables with the status RECIPIENT = "BATHCDBA."
