Disabling Real-Time Alerts outside of RTMT

Running CCM 4.1, we have some alerts setup in RTMT to email people when certain events happen. The schedule feature only allows us to set a begin and end time per day and doesn't allow us to exclude weekends. This causes people to get email bombed on Saturday's, Sunday's, and holidays.
I dug around for a bit in the CCM database to see if there was a table that stored the disabled/enabled state of each alert without luck. Does anyone know where this status is stored and/or if there is a way to disable/enable alerts outside of the RTMT? I would love to be able to run a script to modify these. Thanks in advance!

How to disable REAL TIME QUERY in DG 11gr2 ?

Hi,
With 11gr2, by default, on STARTUP, the standby database is open
-> in READ ONLY mode
-> with Intended State: APPLY-ON
so the ACTIVE DATAGUARD option is in use ....
is there a way to deactivate REAL TIME QUERY permanently,
so whether on STARTUP or STARTUP MOUNT, the standby stay only mounted with Intended State: APPLY-ON
The only way i found is to do the following :
SQL> startup
DGMGRL> edit database 'PHNXENT' set state='APPLY-OFF';
then
SQL> startup mount
DGMGRL> edit database 'PHNXENT' set state='APPLY-ON';
but this can leads to mistake ....
Thanks

it is for standalone database (not RAC)
yes, users can start the database with mount option, but they have to keep in mind that they do not have to issue a "STARTUP",
so it is a production rule that oracle doesn't handle.
Second, it will give a little more complexity in startup scripts (first mount, identify the role, and then open if it is a primary.
In 10gr2 just startup in all cases ....
that's why i'd like to know if there is a possibility to permanently disable REAL TIME APPLY ...

How to carry out real-time or near real-time alerts?

I just wonder when the source audit data transfer to audit vault server, does it done by Refreshing the Warehouse , or another process? Refreshing the Warehouse seems only normalize the raw audit data into the data warehouse. And can we control the frequency of transfering source audit data from soucre to audit valult server ?

I was traced into transfering audit data from source to audit vault server, and found that it's very quickly to get the new audit data from source db into the audit vault server's table named avsys.av$rads_flat, it's almost realtime, but I have no idea about which process has done this, which process? how to control the frequecy ?
Although the server has gotten the new audit data into the avsys.av$rads_flat, the warehouse still cann't get the new audit data whatever I refreshed the warehouse via Audit Vault Console or using command "avctl refresh_warehouse -wait" until 24 hours later. user579967 seems has the same problem, it really frustrated me. Is there anyone knows how ?

Disabling Intego Virus Barrier Real Time Scanning Solved my Problem

I was having terrible problems trying to get time capsule to work with my macbook pro until i permanently disabled Intego Virus X5 Barrier's Real Time Scanning. This solved my problem. Hopefully it might help somebody out there too.

Often times, considering how advanced malware has gotten, a System Restore will simply result in getting infected again. Most infections I've come across tend to occur months before they actually strike and are found. If they are one of those infections that slip in overnight (those JavaScript ones that slip in through Advertisements and infected search results), those tend to infect even the System Restore points. System Restore is a handy tool to have, but it isn't bulletproof.
When such issues happen, MalwareBytes Anti-Malware and SUPERAntiSpyware are wonderful, free pieces of software to have around. Best scanners out there for Malware that are updated daily. To be on the safe side before you start messing with the system anymore, download and install MalwareBytes (http://www.malwarebytes.org) along with SUPERAntiSpyware (http://www.superantispyware.com) and perform a full scan with both scanners. Clean out any infections found, reboot if needed, and then we can go from there to see why the Security Suite is acting up.
When you install the Verizon Internet Security Suite (McAfee under the hood), one of the first things it does is disables the built-in Windows Defender as well as the Windows Firewall, since the Security Suite includes a Firewall and a Spyware scanner with itself. Having two Firewalls and/or real-time scanners in operation can cause some rather nasty problems, besides dragging down system performace. So yes, if the security suite is installed, it's normal for Defender and Windows Firewall to be disabled. When the suite is removed, Defender and Windows Firewall should automatically be re-enabled.

Anyone know if there is an adapter to record audio from an outside source in real time to an iphone 4s or 5s video?

Hi @imobl,
You sound like an Apple support guy who hasn't been able to answer my questions.
To respond to some of the points you made,
- I did not ignore Ocean20's suggestion. If you has read my post, you would have known that I took my phone to the apple service centre where they tried this restore on THEIR machines. I am assuming that Apple guys know how not to block iTunes. So I actually do not understand your point about me trying the hosts file changes on my machine. Do you not believe that apple tested this issue with the correct settings?
- you also give a flawed logic of why the issue is a hardware issue. You mentioned that If I thought that the issue was with the software, i should try a restore and getting it to work. The problem is that my error (23), and many others comes up when the restore fails. And you would be astonished to know that not all errors are hardware errors. Sometimes even software errors prevent restores. Funnily enough Apple itself mention that 'in rare cases, error 23 could be hardware related'.
- all Apple has done so far is replicate the issue. I don not know how anyone can conclude that the issue is a hardware issue.
And by the way, I am not certain that this is a software bug. Again if you read my Posts, you will notice I only want a confirmation,/proof that the issue is hardware related as they mention..
Please refrain do. Responding if there is nothing to add.

Is it possible to disable some popups from FEP Client on the desktop. But how to disable popups from real time protection

Is it possible to disable some popups from FEP Client on the desktop. But how to disable popups from real time protection. This is so that end users who are non technical are not disturbed and only the I.T is aware of the viruses in teh environment.Shahid Roofi

You could set policies which when a malware detected an action perform automatically without user interaction but there is no GPO which stop the notification, one reason could be that when notification keep appearing, then user will know something is wrong
otherwise why FEP should display any warning.

How can I generate a real-time highchart from my database data?

I have looked several links; however, I couldn't find a working demo showing how to implement a highchart using data from a database.
Objective: I want to generate a real time highchart line graph getting data from my database. What I want is very similar to the
HighChart Demo which provides a real-time highchart with randomly generated values. It is also similar by X-axis and Y-axis, for I want my x-axis to be "Time" (I have a DateTime column in my database) and y-axis to be an integer (I have
a variable for that as well in my database).
Please I need help in sending the model data to my razor view.
Note that I am already using SignalR to display a realtime table. I also want to know if it can be used to automatically update the highchart as well.
Below is the code snippet of my script in the view. I have used the code provided in
HighChart Demo link for generating the highchart. Please tell me where should I apply the changes on my code.

How to save data in a 4D array and make partial plots in real time?

Hi, this is a little complex, so bear with me...
I have a test system that tests a number of parts at the same time. The
experiment I do consists of measuring a number of properties of the
parts at various temperatures and voltages. I want to save all the
measured data in a 4-dimensional array. The indices represent,
respectively, temperature, voltage, part, property.
The way the experiment is done, I first do a loop in temperature, then
in voltage, then switch the part. At this point, I measure all the
properties for that condition and part and want to add them as a 1D
array to the 4D array.
At the same time, I want to make a multiple plot (on an XY graph) of
one selected property and part (using two pull-down selectors near the
XY graph) vs. voltage. (The reason I need to use an XY graph and not a
waveform graph, which would be easier, is that I do not have
equidistant steps in voltage, although all the voltage values I step
through are the same for all cases). The multiple plots are the data
sets at different temperatures. I would like to draw connection lines
between the points as a guide to the eye.
I also want the plot to be updated in the innermost for loop in real
time as the data are measured. I have a VI working using nested loops
as described above and passing the 4D array through shift registers,
starting with an array of the right dimensions initialized by zeroes. I
know in advance how many times all the loops have to be executed, and I
use the ReplaceArraySubset function to add the measured properties each
time. I then use IndexArray with the part and property index terminals
wired to extract the 2D array containing the data I want to plot. After
some transformation to combine these data with an array of the voltage
values in the form required to pass to the XYGraph control, I get my
plot.
The problem is: During program execution, when only partial data is
available, all the zero elements in the array do not allow the graph to
autoscale properly, and the lines between the points make little sense
when they jump to zero.
Here is how I think the problem could be solved:
1. Start with an empty array and have the array grow gradually as the
elements are measured. I tried to implement this using Insert Into
Array. Unfortunately, this VI is not as flexible as the Replace Array
Subset, and does not allow me to add a 1D array to a 4D array. One
other option would be to use the Build Array, but I could not figure
out if this is usable in this case.
2. The second option would be to extract only the already measured data
points from the 4D array and pass them to the graph
3. Keep track of the min. and max. values (only when they are different
from zero) and manually reset the graph Y axis scale each time.
Option 3 is doable, but more work for me.....
Option 2: I first tried to use Array Subset, but this always returns an
array of the same dimensionality of the input array. It seems to be
very difficult, but maybe not impossible, to make this work by using
Index Array first followed by Array Subset. Option 3 seems easier.
Ideally, I would like option 1, but I cannot figure out how to achieve
this.
Your help is appreciated, thanks in advance!

Scheduling in Real-Time Java

Hello,
I have some questions concerning how scheduling in fact is intended to be performed in a RTSJ based Real-Time Java System.
As far as I understood, RTSJ requires pre-emptive priority-based dispatching of Schedulable objects.
This means that the execution eligibility of a schedulable entity is mainly its priority.
That causality is reflected within the specification with the (one-and-only specified) PriorityScheduler, which is the base scheduler for actual Real-Time Java applications.
Furthermore, there is a notion of extensibility of that PriorityScheduler described by RTSJ,
in order to provide further scheduling mechanims and feasibility analysis algorithms (please correct me if there are any wrong assumptions).
This is the point, where everything becomes really weird to me ...
As far as I could investigate, in most RTSJ implementations based on a POSIX compliant system underneath (like Java RTS does on RTLinux or Solaris)
each (Realtime)JavaThread is mapped 1-to-1 to a light-weight process on the operating system level (e.g. a pthread).
So far, we have no "green threads" within the JVM, but real LWPs scheduled by the OS.
The difference between "normal" and "real-time" threads lies in the scheduling policy used for that mapping.
While normal Java threads probably map to SCHED_RR or SCHED_OTHER, real-time threads are scheduled by the OS via the SCHED_FIFO policy in order to achieve a better real-time predictability.
However, the OS's scheduling mechanisms automatically make decisions about the right positioning of a LWP within an appropriate run-queue, due to thread's preemption, blocking or release (even dynamic priority changes) activities and its scheduling policy.
That's exactly why I ask myself, what is the need of a Scheduler representation within a JVM?
Furthermore, how a Scheduler extension is able to incorporate with the threading model and the underlying scheduling mechanisms of the OS?
One point could be a situation where a real-time JVM runs directly on top of the bare hardware and has to perform scheduling decisions on its own.
The Scheduler API could then be understood as an extension mechanism of a kind of JVM-intern scheduler (e.g. the PriorityScheduler), thereby allowing scheduling decisions to be made even in user defined Scheduler implementations.
A similar use case for an OS-based scenario could be if a JVM is intended to pass scheduling/threading routines of the underlying OS (eg. a part of the POSIX API)
up to the Java application level in order to provide the opportunity for a kind of application defined scheduling (like e.g. in the MaRTE OS).
Unfortunatelly, after introspecting the RTSJ API, both conclusions seem to me to be wrong.
So far, Java RTS seems not to provide any mechanism for reaction on scheduling events/decisions, neither intra-JVM nor from an underlying OS outside of the JVM.
Furthermore, there is no notion for incorporation with the base PriorityScheduler for making extended scheduling decisions.
I hope this post could bring me more light into the scheduling idea behind Real-Time Java systems as intnded by the RTSJ.
Sincerely,
Vladimir

Vladimir.Nikolov wrote:
That means, that a scheduling policy different to PriorityScheduler can only be assigned to a Schedulable object if it is supported by the OS and the JVM?Well it has to be supported by that implementation of the RTSJ. Howe that is done - ie whether it requires OS support - depends on that VM, the OS and the actual scheduling policy.
It also seems that at the current state of the art the PriorityScheduler representative within the JVM is intended only for manipulating a feasibility set of Schedulable objects (supporting online feasibility analysis)?
However, since user-defined scheduling is not intended by the specification, applications have to rely on the feasibility analysis based on the underlying/supported scheduling mechanisms.
Thus, in the current Java RTS implementation this would be the "default" feasibility mechanism based on the PriorityScheduler.
Unfortunatelly I can not figure out the need of maintaining a feasibility set, since feasibility, as specified for the PriorityScheduler, is a simple asumption that we have "an adequatly fast machine to handle the periodic and sporadic load"?
I actually assumed that feasibility analysis performs real cost budgeting taking into account deadlines and so on, but it seems to be specified simply to make a negative statement always when aperiodic tasks are involved ?The RTSJ scheduling framework provides support for feasibility analysis by defining the admission control methods eg setXXXIfFeasible. However the RTSJ does not, and can not, mandate any non-trivial feasibility algorithm because in simple terms no such general algorithms exist. There are some static feasibility tests in the literature and you could apply those offline to your application (assuming you can find the values of all the "magic" numbers in such formulae - which is generally not the case). At present the RTSJ doesn't support even these simple feasibility tests because blocking-time is not recorded in the release parameters - something being addressed in RTSJ 1.1. In any case unless there is a pluggable framework for feasibility tests it would be a waste of time for VMs to implement them given they can (more) easily be done offline using other tools.
Only dynamic admission control is really of interest and as far as I am aware no such general dynamic admission control policies exist (anything you find in the literature is very context specific). So it is left up to an implementation as to whether they try and define dynamic admission control algorithms - and so far none have because they don't have one.
In "Getting More Flexible Scheduling in the RTSJ" Wellings and Zerzelidis propose some (more or less) "minor" extensions to the RTSJ API in order to enable hierarchical scheduling within the fixed priority framework.
Since Andy Wellings is a member of the RTSJ Technical Interpretation Committee, is there any attempt to evolve the specification in a similar direction as described above, in order to support more flexible scheduling mechanisms and feasibility analysis?If there is ever a RTSJ 2.0 then more sophisticated scheduling support is one of the items on the wishlist. But there's no guarantee there ever will be a RTSJ 2.0

Premiere Pro 8.1 won't play sped-up clip in real-time smoothly

Just upgraded my computer to an x99 MB, Haswell E process (5820k), GTX 970, and 64 GB of RAM (only using 24 GB due to nvidia issue with 32 GB ram +).
I have a few clips from a 5D MKII-III (h264 MOV) that I'm speeding up significantly (2500%).
Premiere doesn't, and has never liked to play sped up clips smoothly for me in real-time. I thought this latest hardware upgrade would help, but same result.
Has anyone experienced this?
I can provide my clip offline if anyone wants to test it.
My CPU util goes up significantly during playback, but doesn't spike on the new system (only 70% ish).

Luke,
I ran your .MOV clip in a fresh project, put it on the timeline, and set the speed to 2500%. Observations below were largely the same (most unexpected by the way!) for 3 very different systems (listed below):
Initial playback was dropping some frames, but didn't really look too bad; CPU is definitely working the hardest for this workflow
After changing two rather random things, all 3 systems could play this back with zero lost frames. Settings included: Memory: set so 8GB is available outside of Premiere Pro (default is 3GB), Sequence Setting: checked Max Render Quality box (default is off), and performed a "Render Audio" on the sequence (this takes less than one second and seems to help a bit).
Rather interestingly, this particular workflow actually seemed to work a bit better when MPE was set to software only (GPU off)
Systems tested included (all running CC 2014):
3 year old x58 6-cor i7-970 with SSD array, 24GB RAM, GTX 480
2x Xeon e5-2687w, 128GB RAM, GTX Titan, single Samsung 830 SSD for everything (OS/Programs/media/projects/swap/cache/scratch)
1x Xeon e5-2687w v2, 64GB RAM, SSD array, GTX Titan
Questions:
What version of Premiere Pro are you using?
How many dropped frames are you getting when you just playback this clip?
Have you ever tried doing just a small project with just this clip (at 2500%)?
Regards,
Jim

Jmx with java real time

Hi David,
my question for now is very general.
can we use jmx with jrts???
Gabi

Hi Gabi,
Some additional information:
- JavaRTS does support the JMX protocol
- JavaRTS supports most of the monitoring & management functionalities provided
by HotSpot MBeans
- some functionalities are disabled by default because they would create jitter (like
getting the stack trace of java threads). Default can be changed through the
realtime.debug MBean)
- JavaRTS comes with a few additional realtime specific monitoring beans.
Note that JMX relies on threads to do its work. These threads are not real-time.
Hence, if the realtime threads (including the RTGC) are consumming all the CPU,
you may not be able to call MBeans to see what is happening and take corrective actions.

Real Time Communication

HI Gurus,
Can any one tell me what is REAL TIME COMMUNICATION.
Also I request information / details on RTCIS.
Regards
Ajoy

Hi Ajoy,
1.1 Application Scenarios for Real Time Communications
There are two classes of applications: client and server. Client class applications have one real-time client per computer, such as the traditional instant messenger (IM) application. Server class applications typically act on behalf of multiple users or communicate with many hundreds of users simultaneously. Server class applications are often based around intelligent applications that interact with users. These applications can be divided into two categories: notification Apps that send information to a client and interactive Apps that accept and respond to a client. A third type of server class applications, Web-based clients, interacts with users through a Web server.
1.2 Notification Applications
Notification Apps are real-time applications that send information to multiple clients from a centralized server (see Figure 1). The one-way transmission means that clients cannot communicate directly with the notification App. Instead, clients must choose which events they wish to receive by using some other technique, such as a Web application.
One example of a notification App is an application that notifies all of the users of a particular e-mail server that the server is about to go offline. Another useful notification App would send alerts in cases of severe weather.
1.3 Interactive Apps
Interactive Apps are applications that allow multiple clients to communicate with a central server in real-time, as Figure 2 shows. They are different from notification bots in that interactive bots support two-way communications with a client. Using this approach, you can build an application that interacts with users in real-time. Within this scenario, there are two main sub-scenarios. The first provides a user with information and waits for the user to respond, such as an application that notifies users about changes in stock prices and then gives the user the option to buy or sell. The second waits for the user to request a session with the App and then responds to requests that the user supplies, such as a calendar application that allows a user to schedule meetings and other events while receiving reminders just prior to the meeting or event.
1.4 Web-Based Clients
Web-based clients provide the same basic functionality as the traditional IM client through a Web interface, thus allowing the widest possible audience to use the application, as Figure 3 illustrates. It also has the side effect of eliminating the need for a user to download local software, which reduces user concerns about the download containing a potential virus. These types of clients are useful to organizations that wish to provide a Web-based front end to their internal IM system. For example, a company might wish to use a Web-based IM client to connect customers with a support group. Doing so maximizes the number of customers that can connect with the support group.
Real Time Communications Data Flow
It's critical that organizations planning large deployments of real-time communications applications ensure that those applications can scale to meet the desired goals. The RTC Client API is very efficient for client class applications for which each client runs on its own computer. To build a scalable RTC Client API application that services multiple clients with a single computer, you need to ensure that the application is scalable when you design it.
The Real-time Communications (RTC) Client API is a set of COM interfaces and methods designed to create PC-PC, PC-phone, phone-phone audio/video calls, or text-only Instant Messaging (IM) sessions over the Internet. Application sharing and whiteboard (An application that displays a window for two users to exchange information) can also be added to PC-PC sessions. Presence information is used to track the location of buddies (or contacts) for communication purposes. This information is available through the RTC Client API on a SIP registrar server.
The RTC Client API:
1.Supports multiparty phone-phone calls
2.Uses SIP-based signaling and presence communications
3.Integrates with the Microsoft Office RTC proxy and registrar server
4.Supports provisioning with ITSPs or third-party corporate-deployed servers
5.Integrates signals over IP and PSTN networks
I hope this will be useful for you.
Thanks,
Swamy Kunche

Real time bpm business scenarios

<b>could some one please clearly explain me real time business scenarios where BPM(XI) implemented, this would help me a lot for my interview preparation</b>.
i really appreciate any help

Hi Vijay,
BPM is mainly used in senarios where extra functionalities are to be done with the source message which cannot be done using the normal mapping and user-defined functions, like
->Collecting of messages till a certain count or for a specific criteria.
->Merging messages
->Spliting messages
->Processing of error files and sending to specific location and sending alerts.
->Parallel processing of two criterias at the same time can also be done using BPM.
Hope this helps.

Real Time kernel questions

I decided to compile myself a new kernel using a PKGBUILD from AUR, which contains Ingo Molnar's real time patch. I know that there are some entries int the wiki about this (Kernel Compilation with ABS, Custom Kernel Compilation with ABS, Kernel Patches and Patchsets), but they don't answer all of my doubts.
The major question is related to my graphic card's drivers. I'm a happy Radeon user using fglrx proprietary drivers. At the moment they are working fine on a vanilla kernel form [core], the problem is whether I would have to do some voodoo to make them work on a rt-kernel? Now I know what is written in wiki about installing Catalyst drivers on a custom kernel, but when on Mandriva I tried to install 8.1 on my rt-kernel, I had to do some tricks and recompile fglrx to make it work. Does anyone tried installing Catalyst drivers ver. 8.2 on a real-time kernel from AUR?
Another thing: I have a .config file from the previous rt-kernel. Would it be suitable for 2.6.24?
Finally, I recently read about grsecurity patchset. Did anyone tried it on Arch, especially on a real time kernel? Any problems?
Waiting for suggestions

broch wrote:first I hope that you understand that RT kernels on desktops are slower than preempt default or vanilla kernel?
I'm using one on my Mandriva 2008.0 and didn't notice any slowdown.

grsec will not work with anything messing up with memory (even Kolivas patches in past had issues with grsec). This can be fixed but then what is the point of enabling hardened kernel with disabled features?
I simply patch vanilla with grsec.
Remember that some pax options are incompatible with X (all explained when option is selected, so no way to make mistake)
finally it works well lowest overhead, best speed and easies to manage among kernel hardening patches (I do not count Apparmor, as this is rather limited tool)
If I understood you, then it's a choice between real time and more security, right?
