Hello all,.
I hope you can help me. We have a 2 node rac. the first node cannot be started due to:

The failed node can be started in exclusive mode, and I'm able to connect to the asm, but of course without disks. When I am trying to mount starts, I get the following:
SQL > alter the data carrier diskgroup.

ERROR on line 1:

ORA-15017: diskgroup 'DATA' cannot be mounted
ORA-15063: ASM discovered an insufficient number of drives for diskgroup "DATA".
ORA-15085: ASM disk "" the size of incompatible sector.

We seem to be affected by the similar problem as written:

kernel cannot be updated thus affecting the ORACLEASM_USE_LOGICAL_BLOCK_SIZE is not possible.
What we do not understand why the failed node has different physical block size / logic. Why the oracle on the failed node linux recognize different value? If it was the same thing, no doubt the cluster could start up:

Thank you for the help

I have changed accounts.

We managed to find the reason. First of all, it is a virtual machine. An expert colleague told me to check the hardware of vmware. We managed to find out that there is a difference of ILO to host vmware hardware. Even if the guest OS virtual material seem to be the same, but the difference between the results of operating system host different logical and physical size of block on 2 nodes. This is the reason.

We had to update the kernel to apply the setting ORACLEASM_USE_LOGICAL_BLOCK_SIZE to repair the block size for clusterware difference. Everyone was puzzled about why, but the most important is the host VMware system in this issue.

Thanks for the help

Discs with right to vote
Hello

How is it possible that the RAC cluster nodes will see only some of the records of voting in the cluster?
I ask because I fell on the topic on Oracle docs: http://docs.oracle.com/cd/E11882_01/rac.112/e17264/adminoc.htm#TDPRC570

If this sutuation is possible, is this normal? How will this affect my cluster?

Kind regards
Igor.
Hello Igor

1. some nodes in a cluster accesses not all discs with right to vote in the cluster?

Laughing out loud...
nodes in a cluster must need access to at least former numbers voting disk 1 or 3 etc...

without voting disk access to the nodes become unhealthy means network and disk heartbeats are not in this case this node restarts.

2. If the above situation is possible, is this normal and how it affects the cluster?
Not possible...
It is not a normal situation

purpose of the voting disk is used to communicate the disk heartbeat and heat network between cluster nodes so without access to voting disk how cluster remain in good health so that nodes must at least
odd numbers of voting drive.

3. (new question) don't exit command "crsctl query css votedisk" discs with right to vote the current node can have access, or is that the command returns a global information?

The crsctl query css votedisk command to view the voting disks used by Services synchronization Cluster, the State of the disks with voting rights and the location of the discs, if they are stored on Oracle ASM or elsewhere.

Concerning
Hitgon

: Cannot communicate with the Cluster ready Services

Hi all
We have a two-node cluster for our QA environment. Version database 11.2.0.2. UNIX people upgraded the kernel version and we relinked binaries. After the restoration of the links, the CRSD is not coming, and therefore the RAC database is DOWN.

Here are some checks:

History of clear ranking with only refers to the cluster

I have a group of UI elements that I save them as a strict type def be reused between various programs. I can send data in each of these elements. However, I use graphic waveform instead of waveform graphs so that I can stack data. In my application, the user can select data at different points in time so I need clear history graphic waveform and then update the graph with the necessary values. It works fine if I make a direct reference from the graph but I can't operate using just the reference to the cluster. I get either a mismatch of type if I use a strict reference, or I don't see the historic property at all if an appending reference is used. I've seen people putting this problem before but had not seen the right solutions that work with just the reference of the cluster. Any thoughts?

In the comic book, do a right-click on the reference to the "table of waveform" and select Create-> constant. Strictly typed constant wire at the entrance of "class of target" of "more class specific.

Access and manipulate elements of the cluster

I have a group of 4 elements. One of the elements is a ring with 4 data entry. Is it possible to manipulate these entires 4 data based on a condition?
For example, when a condition = 1; then 3 ring entries will be disabled and grayed out. When not, all 4 entries must be enabled.

Is it possible to get the local variable for those inputs of the ring in a cluster. or ideas?

Hello

When you right-click the control of the ring, you will have a Create-> property Node-> disabled]

AS LONG AS you call the command is not strictly Type Def or the cluster that contains the control of the ring is not strictly of Type defined, you can use property "Disabled items []" to get the behavior programmatically.

When a condition is true, the index numbers of items that need to be disabled for this hardware node of wire.

Table of clusters and the cluster is a bar counter, how can I change the color individually?

Table of clusters and the cluster is a bar counter, how do I change the color of the bar individual meter for each element of the array? I just realized that you cannot change the properties of an element of the array without changing everything. For scale, I had to make digital for each graduation of the scale indicators so that each measure meter in the table in the cluster has individual scales. I also had to do some calculations for each barmeter to display the correct proportions of 0 to 100% on the scale. Now, I'm stumped on the color of the bar counter. Basically, if the value exceeds a set value, the meter bar should turn red. It must be in a table to be infinitely scalable.

Thank you

Matt

And yet anothr approach...

Right click on the bar of > Options to fill > maximum fill.

The fill color of the same color as the background color, then make the background color transparent.

Drop a box of color BEHIND the bar and the size correctly.

He has this strange background 3D with flat bar, but what the Hey, his relatives. If its important a custom color box.

How does the cluster?

Hi all

I am subsequently helps him learn how to use the cluster to reduce the number of inputs/outputs, but it is quite confusing that how do you know which is which. It follows from the order, whether or not we have added to the cluster? I put a cluster contains 4 numbers DBL as an entry of my Subvi. I name the elements of each DBL as A, B, C, D. In the main code, I create a cluster contains 4 DBL and trying to feed on this cluster in the Sub - VI. But how do I know what number I feed in the main code is A, B, C and D?

For example, I create a Subvi with the participation of a single cluster. The cluster has 4 numbers DBL named A, B, C and D.

Now if want to feed a cluster in this sub - VI, I create a cluster and connect the 4 digits in this cluster. But if I use the bundle cluster, I need to connect the number in order thus to fill A, B, C and D. But if this Subvi was created by someone else, how can indicate the order of the elements in the cluster WAITED?

First, you must give the elements of the cluster in the control Subvi the same names (A, B, C, D) as used in the VI call and also to ensure that the order of cluster is the same. If you are not sure fight the cluster command, you can reorder the items (right click) and select the desired command. And Yes, the initial cluster order is the order in which you have added the items.

Generally, it is preferable that the cluster a typedef and used worldwide. This way to the typdef change is propagated to all the places where it is used.

It is often more auto-documentent and cleaner to use together and ungroup by name. A constant of diagram of typedef wire upward 'bundle by name' to make the labels available.

Just a quick question about the appearance of the cluster

Hello, this is Matthew, just a quick question about the appearance of the cluster

Is there anyway to rearrange the order of the elements? I know cutting automatic resizing, I could move the items by hand. But if I use the cluster somewhere else, I have to move the items again...

What I want is of the order of "Mx My Mz Ax Ay Az Temp voltage CS".

Is there a quicker way to deal with?

THz so much!

You can right-click the border of the cluster and choose "arrange control cluster...". "The user interface is not as intuitive as it could be, but it will allow you to reorder items. If you use the cluster in several places, you should make the cluster in a type definition and replace all current uses of the latter with the type definition, so that they all match. They will also update automatically when you make changes to the type definition. Otherwise, you could have a situation where you have multiple groups with the same data types, but with elements in a different order, and your data will be getting a new denominated, when wire you the whole clusters. The data will be in the same order, but given that the item labels are in a different order, you can't get the data you want, when ungroup you by name.

Insert into the cluster by string name

Hello

I am writing a Labview program to query .NET database management system and get the connected device (like USB CDC) listed with Port of corresponding Com, VID, PID, manufacturer of SN name ect...

I got to the point where I get the channels I need and want to organize them in a cluster table.

Here is my code, I wanted a better way to replace section circle of the code.

Basically, I can get programmatically the cluster name, but when the cluster wads, I can't figure out a way to do it programmatically inside the while loop: a loop on the number of items in the cluster and by placing values in the right place.

Is it possible to do?

Thank you very much

Amine

Altenbach says:

If the cluster contains exactly three elements of the chain (nothing else!) and they are classified as in the node of your 'bundle by name", all you have to do is on the"table of cluster"output size 3 and it wire in a table build node (upper entrance wired to your array of cluster and botton imput cable to the new cluster) Wired output by the right side of the image).

Here is a simplified illustration which simply sets the value of the label. (top image). Because the labels are defined at compile time, all you need is perhaps to get the names of once at the beginning of the program, and then use a range of simple string instead.

Another possibility would be to use the reference to the element to set the value inside the loop, and then get the final cluster value later (at the bottom of the image).

(There are some simplified examples. All you need is to replace the code that gets your new string instead.)

Initialize the cluster with data types different (lots of data)

Hello

I have data, which are composed of different data types. First of all, I have initialize cluster with these types of data and then "print" to light (photo). In case of photo data carries 8 characters than ja 4 floats. It was easy to initialize, but here's the question: How can I do this even if I have data that look like this (interpreter):

floating point number

name char [32]

Short value [16]

What I create loooong cluster which have a fleet of 32 characters, 16 short films? Or I can create these 'paintings' in a different way?

THX once again

-Aa-

I suggest using the table-cluster and configuration of the cluster size to match the size of your berries, then package these groups together. In terms of storage of LabVIEW, there is no difference between a group of

floating point number

Name1 tank

name2 tank

...

short value1

short value2

...

and a bunch of

floating point number

-> cluster shipped from

Name1 tank

name2 tank

...

-> cluster shipped from

short value1

short value2

So you can use the cluster table to get the right sizes rather than individually create all these values in a single giant cluster.

How to use the cluster VI elements in TestStand

I have a LabVIEW VI, which has an output cluster containing 10 hooks and 10 Boolean values. In TestStand 4.1.1 I inserted a VI of pass/fail in my test sequence and that related the LabVIEW VI VI of success/failure. I have seen all the strings and Boolean values listed separately in the table of settings under the tab module. I wanted to have each of these cluster items listed in the report, so in the value fields, I inserted Step.Result.ReportText, but elements of the cluster were not included in the report.

I then tried to turn the cluster in a custom, data type that has been a success. In TestStand to sub tab module to LabVIEW adapter, I created a customized data type under space corresponding to the cluster of exit from VI. If I go in the variable pane of TestStand, I can see the custom data type and each of the 10 channels and 10 Boolean values are present in the form of individual variables. I tried right clicking on the variables of cluster and selecting Properties and then go advanced and checking the PropFlags_IncludeInReport box, but the values of variables have not appeared in the report.

What I want to do is to have each of the string values and Boolean values appear in the test report. So what I am doing wrong?

Hello

You can use the additional result.

You assign inhabitants out of the VI and then you can insert an Additionl result for this step. See in the parameters of the step.

Don't forget to insert your Local in the area concerned in the additional result.

Table 2d to the cluster

Anyway is to convert a table to 2 dimensions to a cluster? im making a parking lot (which has columns and rows of parking spaces) and I want to convert it to an inorder to cluster to unbundle the components to use them for some other stuff, how do I do this?

A cluster is a set of elements, so it makes no sense with regard to a 2D array.

If you have a 2D array, you will need for each of the items in the index and assign them to the cluster.

Another possibility is to reshape the 2D in a 1 d table table, and then use the table to cluster (with the number of items correctly defined in the right click menu of the function).

shows how to create the cluster of refnum user event

I try to understand and copy this sup - VI, but I have problem in the construction of this cluster of refnum user event, and how to build the local variable?

\

It looks like your confusion comes from not knowing how to make a group of data, it's an accurate observation?

To a cluster, you must create an empty cluster and new drag and drop in the cluster. In this case, how to make a refnum of the event, which is the right type of data, you must follow these steps:
1. Set up the user event create with datatype.
2. Right-click in the output, and then click on create Constant. This constant is now your refnum of correct data type
3. Drag the new constant to a cluster to add it to the cluster. This could be within your DataSet defined Type called "Private Events" or another cluster.
If you change the data type of your event, the wires that connect this event to the cluster of data interrupts the measure where you will have a data type mismatch.

Help with the cluster in table for the cluster size difference, please!

I will admit to still hurt with the berries of LabVIEW, and as usual, the behavior in the vi attached is meaningless to me! The attached vi shows a cluster 6 element being converted into a table, then immediately to a cluster. The reconstructed cluster has 9 elements, even if the table size indicator display properly 6. How to maintain the initial cluster size when converting to and then since then, a table?

The f

Well, if you have worked with context-sensitive help running you would see:

"With the right button of the function and select the Size of Cluster in the context menu to set the number of items in the cluster."

The default is new. The maximum cluster size for this function is 256. »

You must set the size. There is no way for the function to know how many elements in the table.

The loss of the right to vote disk hogging the Cluster?
