Why there is only a single process RFS in v$ managed_standby?
We build a backup using Oracle Dataguard 10 g server.Steps to start this server are:
SQL > STARTUP NOMOUNT;
SQL > ALTER DATABASE MOUNT STANDBY DATABASE;
SQL > ALTER DATABASE RECOVER MANAGED STANDBY BASE DISCONNECT FROM the SESSION.
When we show the process using v$ managed_standby
SQL > SELECT PROCESS, STATUS, THREAD #, SEQUENCE #, BLOCK #, BLOCKS FROM V$ MANAGED_STANDBY;
the result is
STATUS OF PROCESS THREAD # SEQUENCE # BLOCK # BLOCKS
--------- ------------ ---------- ---------- ---------- ----------
ARCH CONNECTED 0 0 0 0
ARCH CONNECTED 0 0 0 0
MRP0 WAIT_FOR_LOG 1 81 0 0
RFS IDLE 0 0 0 0
There is only a single process RFS. Whereas, when I read articles on the GDO, they mention that there are two methods of RFS.
How to create the RFS another process? Should be to identify what are the parameters?
Thank you very much
Kind regards

Strange double NAT, although there is only a single router
My ISP (RCN) changed my modem at a speed greater than one. Although a router built-in, I told them that I didn't use their router, only my Time Capsule, so they disabled. However, my Time Capsule kept gives me an error message Double NAT and amber flashing against Green, even though everything seemed to work (wireless and wired) and said that I should switch DHCP and NAT to bridge mode. Correction of the error, but I do not understand what caused the Double NAT if there is only a single router. The ISP Technical Support people confirmed their control center is not the router feature on in the new modem, I ask. They also said that their network supports DHCP, although they have other who use the Bridge Mode, although they do not support. And they knew nothing about it, he said to ask Apple. They also offered to switch back, but because this modem is faster at the same price. (He called a bypass gateway 3-in-1). Many people online told not to use his router, it's why I unplug it and only use the time Capsule.
So if someone can give me feedback, I'd appreciate it. I must:
1. keep running the new modem and my Time Capsule in Bridge Mode.
2. run the new modem in DHCP mode, as they put in place and do not worry Time Capsule seeing amber / flashing Double NAT error.
3 swap back to the previous modem, which was 50 Mbps against it with (theoretically) 155 Mbit/s (it's only works in 50-70).
I'm not really all that, but I hope that one of you maybe. Thank you!!!
Although a router built-in, I told them that I didn't use their router, only my Time Capsule, so they disabled.
ISPS often make the mistake of simply turn off the radio on a modem/router...which service does not disable the router function of the device. You still have a wired router when ISPS are making this mistake.
However, my Time Capsule kept giving me an error message Double NAT
This confirms again that the ISP has not disabled the function of the router to your modem/router. On some modems/routers or gateways, it is not possible to get the device to act as a simple modem.
The ISP Technical Support people confirmed their control center is not the router feature on in the new modem, I ask.
The fact remains that you wouldn't see a Double NAT error unless the ISP system acted as a router... Despite what people of PSI say. You may need to get a 2nd or 3rd person-level support, who knows what they are doing.
1. keep running the new modem and my Time Capsule in Bridge Mode.
Yes, if you want to avoid the mistake of NAT Double... what you are doing. But, the time Capsule will not be your router. The device of the ISP will be.
2. run the new modem in DHCP mode, as they put in place and do not worry Time Capsule seeing amber / flashing Double NAT error.
This only if you willing to accept the fact that the ISP did not correctly change your gateway to make it work as a simple modem only. You might be able to get away with a Double NAT error on a simple network, but there is no reason more complicate things with a misconfiguration in unless whether there are a few reasons to do it and it can't be avoided.
3 swap back to the previous modem, which was 50 Mbps against it with (theoretically) 155 Mbit/s (it's only works in 50-70).
Your decision if you want to run a simple modem with time Capsule, or accept the fact that the time Capsule won't have your router when it is configured in Bridge Mode, or you see a Double NAT error on the network.
If it were me, I would go back to what I know will work properly... the simple modem and time Capsule as the router.

create a business model when there is only a single source table
Hello
How to create a business model when there is only a single source table in the physical layer
Concerning
SwathiIt is very well possible and feasible. His name as a single Table model. Good example is HIS domain system where we have just one physical source. No need to create aliases in physics. Just use the same table twice in the MDB with a single logical table as a model made... As for example the number of users (aggregated). Then apply normal complex participate MDB and present in the presentation layer.

How to hide a column in the report when there are only zeros.
Hi Experts.,.
Is it possible to hide a column in the report when there are only zeros.
Thanks in advance
VincentVincent Krishna wrote:

VincentNo out-of-the-box, but there are several workaround solutions if you want to continue an any of them:
(1) use a view selector. A single report will be a pivot table with the column, the other will have the same report less column. Users can switch reports.
(2) use a column selector. The two choices would be this column or an empty space. If white is chosen (because the user has no values), the column "will disappear" according to the report.
(3) guided use NAV. This method involves the intervention of the user. Build a small report using the single column and put a filter "is not equal to" 0. Because there is only a single column, so all lines are 0, the report returns no rows.
Use this report in the properties of guided navigation from one section of the dashboard. Assign to this "If the report returns lines" and put the report that contains the column in this section. Now add another article on your table edge and in the properties of guided navigation of this section, set on "If the report will return no rows" and it points to the small report as well. In this section, put a second version of your report without the column in it.
When the column contains all zeros, the second section with column will not display in it; the first section is not displayed. When at least a line contains a value not zero, the first section is displayed with the column, and the second part will not be.

single process SV - required generation
LV 2011 SP1 (only use DAQmx, GPIB, & RS422, not in real time)
Can't find a quick answer for that. I know how to build and deploy the network published SV with an EXE but not single-process.
I inherited someone of code that uses 2 unique processes shared in a unique LVLIB variables.
(1) the LVLIB container must be included in always included to build?
(2) are the included MS - SVs automatically included in the EXE?
(3) the Source file settings requires a line item for the LVLIB? It can simply be assigned to the item *.exe?
(4) because there is just no network not associated with SV, I see no reason to include the EVS element for installation of LVRTE. True?
(5) possibly related: once built and launched, the application cannot locate the typedef used for one of the MS - SV the typedef is used elsewhere in the code (so should be included in any case).
Thanks for a quick reply.
Dave
You did not say what the real problem - exe can not be built at all? It does not start? Something works do not?
As for point 5), go to the SV type data options and choose Disconnect in typedef (or something like that). I had a lot of problems with SV binded to typedef, they works just not in applications applications (in fact, don't use no SVs in exes and you'll do just fine ).

On my menu CC drop down why is that only Lightroom app that doesn't have a CC
I historically used Lightroom as a single product purchased and recently I bought the creative cloud.
As a new user, I am very familiar with things, but I've noticed on my cloud creative drop-down list containing a list of all my applications, I noticed that each of my apps conclude with CC in the end.

Photoshop CC
Bridge CC
Edge inspect CC
Scout CC
Lightroom NOTHING?
On my drop CC why is that only Lightroom app that doesn't have a CC at the end of Lightroom.
The system has recognized my old Lightroom and there no installed a CC version or is it the same for everybody out there and if so why?
Why no CC on the drop-down list after the word Lightroom?
Why no CC on the drop-down list after the word Lightroom?
Nothing to worry about. It's the same for everybody and it's normal.
Lightroom does not follow the version numbering (again) Cloud. She always had her own version numbering.
When the cloud came out, there was no included Lightroom.
Added Adobe Lightroom to the cloud later but never added CC to the numbering. So yet another layer of confusion has been added to the management software Cloud versions.
There are now two separate versions of Lightroom:
- 5.6 Lightroom (perpetual license, does not include Lightroom Mobile)
- 5.6 Lightroom (a cloud which includes Lightroom Mobile)

variable single process shared with the single element fifo reading arbitrary values
Hello
my request in real-time has a motion control loop and a loop of data acquisition. Before the move, the starting position is read once in the motion control loop and recorded as a shared single process with fifo variable single active element (I want to save only the last value). The starting position is then read several times in the loop of the acquisition of data and compared to the actual position. The movement is stopped in the DAQ loop when the difference between the starting position and the actual position reaches a certain displacement of the target.
Now to my problem: the starting position is read in the loop of data acquisition of the variable correctly shared in the first round after having been written. Then it keeps read an arbitrary value that I have no idea where it came from. How can this happen?
I summarize: I write the starting position once and then read it several times to calculate the actual shift...
Thanks in advance for any help! Kind regards
Grun80
Hey,.
It is a strange behavior, usually the variable should return the last value written. You write the variable in another place of the code too? You debug the application?
What is the RT platform you are working? Version of LabVIEW?
I suggest using a "functional Global Variable" and see if you still get this random values.

Why my filezilla only concert to a server?
Why my FileZilla only concert to a server?
Hi MELGENDY,-You receive an error message trying to connect to a Filezilla on the server?Disable the installed antivirus software, if any, and also disable the firewall and check if that helps connect to the server without any problem.If the problem is resolved, you may need to contact the manufacturer of the program for the settings that can be changed or if there are other updates for this program.
Note: Antivirus software can help protect your computer against viruses and other security threats. Have a computer without any security software can cause a potential danger to your computer. Therefore, make sure to activate the firewall and security software once you are finished with the test.
If that doesn't work, post your query in Filezilla Forum for assistance on this issue.
