snapshot with db link.

Hi all

I'm alittle puzzle as to why with a s/n privs,

I am able to create this summer with instant success with my dba account.

in db A

create the snapshot DGF. TBL_GHB_HOME REFRESH QUICKLY START WITH SYSDATE NEXT trunc (SYSDATE + 1) + 2.5/24 with the primary key AS SELECT * FROM DGF. TBL_GHB_HOME@B;

the strange thing is, I'm able to do for some schemas, there is little, I open a session specifically as this drawing to create the snapshot.

I don't know, when I do this in DB-> SELECT * FROM DGF. TBL_GHB_HOME@B;

I couldn't make the selection with the error as "remote database does not exist"

but has managed to create instant success.

Hi Paul M

This is the point!

SQL > conn / as sysdba

Connected.

SQL > create materialized view scott.test11_mv

full 2 refresh with rowid

3 select * from test.test@test11;

Materialized view created.

SQL > select count (*) in the test.test@test11;

Select count (*) in test.test@test11

*

ERROR on line 1:

ORA-02019: description of the connection to the remote database not found

Why are you able to create the mv even when you can not-> select count (*) in the test.test@test11;

strange, isn't it? I guess that is because of the materialized... create statement which means simply run the script to create materialzie and to ignore what else is in the rest of the statement, was it access the data from a different database. Laughing out loud

  • Snapshot with large RDM

    Hello

    I have a virtual machine with 2 virtual disks and 2 RDM. The 2 virtual drives are each about 20-30GB. The RDM is 2 TB each. Can I make a snapshot with just the 2 virtual drives? What is the best way to save before making changes

    other than the backup.

    Thank you

    Mike

    Hello

    If the RDM are in mode physical then instant does not apply to the RDM. If your RDBMS is in virtual mode, then you can make snapshots of the RDM, but to do this, I'll make sure you have PLENTY of space, up to 2 tablespoons available just in case you do something touches all the blocks of the RDM.

    Personally, I keep large RDMs like physics and save them within the virtual machine to an external source. Mitigate the need a lot of disk space.

  • XIA Pixie-4: can I use it with MXI link?

    Dear colleagues!

    Please advice me can use digital Pixie-4 (from manufacturer of XIA) spectrometer with MXI link if I know that there is a special software for LabVIEW 8.5 kit?      This kit has been tested only on 8174 embedded plc and without having tested with MXI link.

    I heard somewhere, if the software package supports LabVIEW 8.5 then MXI link will also work.

    Current 93,

    How works MXI is that he essentially developed bus PCI/PCIe to your PC to allow additional devices working on it. Since it is an instrument of third parties, we cannot make any guarantees about the reliability of their products in some systems. There are some third-party products that can not handle operating systems 64-bit, as well as some computer manufacturers who are unable to manage bridge PCI expansion and this should take into consideration when you decide to use a MXI card in a PXI chassis. However, I believe that as long as your device Pixie-4 of XIA is compatible with the version of Windows and any software on this computer, then it should not cause problems with start-up and operation. Devices may also not appear in measurement and Automation Explorer because they are third-party devices, however, if you have software installed on the PXI-8184 controller, then the same software should work on the desktop PC that uses the MXI map as the same data to which are connected the 8174, is accessible by the MXI Board.

XXX.251 and codec on XXX.252 both are the same subnet.

    Given that a single LAN port, how can I access the web interface of the codec to check and perform pairing? If in case, the codec is on firmware older supporting not pairing function so how can't I perform manual synchronization. Cannot access the ISDN link by series.

  • Yet created the animation flash with HTML link

    Having some problems with (in CS6) recently.

    Use it to create a flash with the link of file HTML file.

    Flash is installed and running, but when clicking on the index file I just get the black box and nothing else in the web browser.

    Tried Firefox, IE and Chrome, all with the same results.

    It worked well on 09/05/16 but the 15th, it had stopped working.

    The play flash file directly works without any problem.

    Any help or ideas would be appreciated.

    I took a few minutes. An old yet to Flash projects displays the player controls and does not work. A new export shows no control and does not work.

    Nothing has changed in still (it has not been updated for a long time). Flash (23.0.0.162) and I don't think that has changed. I don't remember when it worked last.

    So I headed to the forum Flash and discovered that it was a new version of flash (5 days ago) which has the default value no local file access. It's a security issue. See this link for the workaround:
