Counter for bram addressing

Hello,
i want to store incoming data @ 300MHz in a bram. The address width is 16 bit (65535 elements).
The address generation consists of address incrementation and address comparison since the bram will be devided into segments with each segment having its own address space within the bram.
To sum up the timing failed due to the address generation for the bram.
How to solve this timing violation.
Best regards

I do all of the incrementing and comparing using DSP's instead of fabric logic. You have to do a bit of reading to figure out what all of the configuration options do, but once you do the DSP's are fairly easy to use.
Here is one implementation of a simple counter: when iCount is high, the DSP counts iClk cycles. You can see the pattern detect parameters if you are comparing to a constant value or you can use the DSP to subtract two changing values and compare to zero.

Find total count for Address Book?

In Snow Leopard it was easy to find the "Total Count" for ALL CONTACTS. As soon as you clicked on ALL CONTACTS or even a GROUP in all contacts the amount showed at the bottom of the screen. LION appears to be different. I know you can click on ALL CONTACTS, scroll all the way down to find the total number of contacts (a lot of trouble). However, if you click on a GROUP the total does not show "at the bottom"??? You can go to Address Book > Edit > Edit Dirtribution List and see the totals of individual groups but ALL CONTACTS is not shown because it is a "distribution" of all contacts. Question is: Is there an easy way to find the total count not only for ALL CONTACTS but including GROUPS with out having to go to so much trouble?

I find that if you have a critical number of cards in a group it will show the total number at the bottom of the list when you scroll down (I agree, a real nuisance!). I'm not sure what the critical number is, but I have lists with 20 cards and it doesn't show, while a list of 40 does show the total.
I am not able to choose Edit > Edit Distribution List, since it is always greyed out. Is there are trick?
I really find that Address Book in Lion has lost functionality – don't understand the change to a "book" format where you have to flip back and forth – would much prefer a 3 column format.

Count() for each group, but only groups having 1+ element like... AND all elements like...

There are tables(and columns) like:
'Clients'(clientID)
'Houses' (houseID)
'Visits' (clientID, houseID, visit_date)
'Contracts'(contractID, houseID, clientID, rentDate_from, rentDate_end)
I have problem with writing MS SQL query of this kind:
how many visits to houses did each client, before renting one of them?
Its easy to count total number of Visits for each client, listing all visits + group by clientID and selecting count(*) for each group.
Lets say this is select_1, and select_2 is listing all Contracts for all clients.
Select_1 is not answer, because count must be performed only on groups, which:
-have at least 1 row "like" row in select_2 (it means that at least one of visited houses was rented, because it can happen that client visited few houses, but rented other, not visited house). my idea for this is comparing select_1 and select_2 with:
"where s1.clientID=s2.clientID and s1.houseID=s2.houseID"
-each group must have all rows(visits) with date of same day or earlier than contract date
maybe: "datediff(day, s1.visit_date, s2.rentDate_from) >= 0"

In future, please provide proper DML, DDL and example data, like I have for you below.

CAPWAP: Retransmission count for packet exceeded

We are noticing that WLAN-APs with HREAP-setup are jumping between different remotely located WLCs.
The APs are LAP1131 and LAP1242 with IOS 12.4(21a)JHC and WLC 4402-50-K9 with 6.0.202-image
All starts with the following Log-entries in the WLAN-APs:
*Jan 24 08:22:50.036: %CAPWAP-3-ERRORLOG: Retransmission count for packet exceeded max (CAPWAP_ECHO_REQUEST., 1)
*Jan 24 08:22:50.036: %LWAPP-3-CLIENTEVENTLOG: Switching to Standalone mode
*Jan 24 08:22:50.040: %CAPWAP-3-ERRORLOG: GOING BACK TO DISCOVER MODE
*Jan 24 08:22:50.040: %DTLS-5-SEND_ALERT: Send WARNING : Close notify Alert to 163.157.1.101:5246

*Jan 24 08:23:00.093: %CAPWAP-3-ERRORLOG: Selected MWAR 'SGOTWLC03'(index 1).
Who can tell me the reason for this behaviour ?
Is it possible to tune the CAPWAP-parameter retransmission count ?
Thanks in advance
Wini

Going to try to answer this a different way for anyone Googling this who needs an answer.
"Is it possible to tune the CAPWAP-parameter retransmission count?"
Yes. See here:
http://www.cisco.com/en/US/docs/wireless/controller/7.4/configuration/guides/consolidated/b_cg74_CONSOLIDATED_chapter_01110110.html
Browse to your WLC.
Choose "Wireless" from the top bar.
Under "Access Points" on the left, choose "Global Configuration."
In the main panel off to the right you will see "AP Retransmit Config Parameters" with 2 options: "AP Retransmit Count" and "AP Retransmit Interval."
AP Retransmit Count is how many times it will try to contact a WLC before failing. Maximum is 8.
AP Retransmit Interval is how long between each try. Maximum is 5.
(AP Retransmit Count) * (AP Retransmit Interval) = How long the AP can go without talking to a WLC, in seconds.
If you are using FlexConnect Local Switching and FlexConnect Local Auth, the AP SHOULD still be able to handle clients during this timeframe.
When an AP cannot contact a WLC...
Step 1.) When the retransmit count (max 8, with a max 5 second interval, so 40 seconds max) is exceeded, the AP goes into Standalone mode (similar to Autonomous) and tries to contact a WLC via its static IP for apprx 5 minutes.
Step 2.) If unsuccessful, the AP switches to DHCP, renews the DHCP lease (to get a new IP address) and tries again to contact a WLC for apprx 3 minutes. This repeats 3 times, for a total of apprx 9-10 minutes.
Step 3.) If after step 2 the AP could still not find a controller, the AP reboots itself and starts at Step 1 all over again. Reboot takes apprx 2-3 minutes.
Note if using DHCP addresses, the process may start at Step 2.
Yes, the maximum time an AP can be out of contact with its WLC then is 40 seconds. If you're just using CAPWAP to configure and reconfigure APs which are otherwise nearly autonomous, this can be quite the annoying level of neediness.
"Who can tell me the reason for this behaviour?"
I believe this behaviour is to ensure management capability, and also to support some of the more "interesting" (for lack of a better term) reasons for CAPWAP... maybe wireless client mobility, remote switching, remote authentication, etc. In those scenarios you DO want your APs to be "needy."

Hi All,
Am new to OBIEE.Pls help in this regard.

pls help in this regard and where is the excat problem?
Thanks,

How do I show a count for rows that don't exist?

Hi, I'm trying to count the number of records grouped by rank(B,C,R),month,and year. Basically, anytime a part fails testing a record is entered which records the failure Rank and occurrence date. A record is only inserted if a part failed for specific rank. So not all 3 ranks will have entries. I'm able to count all ranks by month,year that do exist. But how do I get values of 0 for the ranks that don't exist? I just created a table qa_rank that has just one column rank with 3 records(b,c,r). but its not being used as of now. rank is just a column in qa_occ record.Here is my query.
select to_char(occdate,'YY') as yr, to_char(occdate,'MM') as mn,
rank, count(occdate)
from qa_occ
where q.occdate between '1-Apr-2005'and '31-Mar-2006'
and q.supplier = '11107'
group by to_char(q.occdate,'YY'),to_char(q.occdate,'MM'),q.rank
order by to_char(q.occdate,'YY'),to_char(q.occdate,'MM')
which returns this
YY MM RANK COUNT(OCCDATE)
05 09 C 2
05 10 C 2
05 11 C 1
05 11 R 1
06 01 C 3
06 02 C 1
06 03 B 1
06 03 C 2
I need it to return C,B,R for everymonth. If no records exist then the count for the month,rank should be 0. Any ideas? Thanks.

something like:

Get the Count for each row

I'm trying to get the count for each row to total count for each month
Something like this
Hardware | Jan
Monitors | 5
Processors | 137
Printers | 57
etc........
How can I write a query for this. I can get the Hardware column but don't know how to get the next column.

If you can provide more data like sample input DML statements it would have been wonderful..
Assuming is , you need a pivot. Here is an article on basic Pivot..
http://sqlsaga.com/sql-server/how-to-use-pivot-to-transform-rows-into-columns-in-sql-server/
something like this may be..
DECLARE @Input TABLE
Hardware VARCHAR(20),
[Date] VARCHAR(20)
INSERT INTO @Input VALUES('Monitor', '01/01/2014'), ('CPU', '01/01/2014'), ('Monitor', '01/03/2014')
, ('ABC', '01/01/2014'),('Monitor', '02/01/2014')
;WITH CTE AS
SELECT Hardware, LEFT(DATENAME(M, [Date]),3) AS [MonthName] FROM @Input
SELECT *
FROM
SELECT Hardware, [MonthName], COUNT(Hardware) AS Count FROM CTE GROUP BY Hardware, [MonthName]) a

How to get row count(*) for each table that matches a pattern

I have the following query that returns all tables that match a pattern (tablename_ and then 4 digits). I also want to return the row counts for these tables.
Currently a single column is returned: tablename. I want to add the column RowCount.
DECLARE @SQLCommand nvarchar(4000)
DECLARE @TableName varchar(128)
SET @TableName = 'ods_TTstat_master' --<<<<<< change this to a table name
SET @SQLCommand = 'SELECT [name] as zhistTables FROM dbo.sysobjects WHERE name like ''%' + @TableName + '%'' and objectproperty(id,N''IsUserTable'')=1 ORDER BY name DESC'
EXEC sp_executesql @SQLCommand

The like operator requires a string operand.

Example:
DECLARE @Like varchar(50) = '%frame%';
SELECT * FROM Production.Product WHERE Name like @Like;
-- (79 row(s) affected)

How to get total number of result count for particular key on cluster

Hi-
My application requirement is client side require only limited number of data for 'Search Key' form total records found in cluster. Also i need 'total number of result count' for that key present on the custer.
To get subset of record i'm using IndexAwarefilter and returning only limited set each individual node. though i get total number of records present on the individual node, it is not possible to return this count to client form IndexAwarefilter (filter return only Binary set).
Is there anyway i can get this number (total result size) on client side without returning whole chunk of data?
Thanks in advance.

Hi,
Thanks for suggesting a soultion, it works well.
But apart from the count (cardinality), the client also expects the actual results. In this case, it seems that the filter will be executed twice (once for counting, then once again for generating actual resultset)
Actually, we need to perform the paging. In order to achieve paging in efficient manner we need that filter returns only the PAGESIZE records and it also returns the total 'count' that meets the criteria.
If you want to do paging, you can use the LimitFilter class.
If you want to have paging AND total number of results, then at the moment you have to use two passes if you want to use out-of-the-box features because LimitFilter does not return the total number of results (which by the way may change between two page retrieval).
What we currently do is, the filter puts the total count in a static variable and but returns only the first N records. The aggregator then clubs these info into a single list and returns to the client. (The List returned by aggregator contains a special entry representing the count).
This is not really a good idea because if you have more than one user doing this operation then you will have problems storing more than one values in a single static variable and you used a cache service with a thread-pool (thread-count set to larger than one).
We assume that the aggregator will execute immediately after the filter on the same node, this way aggregator will always read the count set by the filter.
You can't assume this if you have multiple client threads doing the same kind of filtering operation and you have a thread-pool configured for the cache service.
Please tell us if our approach will always work, and whether it will be efficient as compared to using Count class which requires executing filter twice.
No it won't if you used a thread-pool. Also, it might happen that Coherence will execute the filtering and the aggregation from the same client thread multiple times on the same node if some partitions were newly moved to the node which already executed the filtering+aggregation once. I don't know anything which would even prevent this being executed on a separate thread concurrently.
The following solution may be working, but I can't fully recommend it as it may leak memory depending on how exactly the filtering and aggregation is implemented (if it is possible that a filtering pass is done but the corresponding aggregation is not executed on the node because of some partitions moved away).
At sending the cache.aggregate(Filter, EntryAggregator) call you should specify a unique key for each such filtering operation to both the filter and the aggregator.
On the storage node you should have a static HashMap.
The filter should do the following two steps while being synchronized on the HashMap.
1. Ensure that a ConcurrentLinkedQueue object exists in a HashMap keyed by that unique key, and
2. Enqueue the total number count you want to pass to the aggregator into that queue.
The parallel aggregator should do the following two steps while being synchronized on the HashMap.
1. Dequeue a single element from the queue, and return it as a partial total count.
2. If the queue is now empty, then remove it from the HashMap.
The parallel aggregator should return the popped number as a partial total count as part of the partial result.
The client side of the parallel aware aggregator should sum the total counts in the partial result.
Since the enqueueing and dequeueing may be interleaved from multiple threads, it may be possible that the partial total count returned in a result does not correspond to the data in the partial result, so you should not base anything on that assumption.
Once again, that approach may leak memory based on how Coherence is internally implemented, so I can't recommend this approach but it may work.
Another thought is that since returning entire cached values from an aggregation is more expensive than filtering (you have to deserialize and reserialize objects), you may still be better off by running a separate count and filter pass from the client, since for that you may not need to deserialize entries at all, so the cost on the server may be lower.

Table creation Error "Ref Count for this object is higher than 0"

Hi All
I have a problem in creation of table using SDK on a button event. I have a procedure to create tables and fields. If I call this procedure on a menu Event than it works fine but If I call this procedure on a button event than It gives error "Ref count for this object is higher than 0" . I know this error occur When an object does not release after creating a table. but this error occur at when first table is created. My code it given below. plz see and give me your valuable suggestions.
Dim oUserTablesMD As SAPbobsCOM.UserTablesMD

Hi Gorge,
The "Ref count error..." usually occurs in case of Meta Data objects not being properly cleared. And yes, you have got the error in the right place, generally while creating tables / fields / UDOs. For this, you just need to clear the Meta Data object (At times even DI objects like Record Set) once they are used.
Eg: Release these objects in the below way in a Finally Block.
System.Runtime.InteropServices.Marshal.ReleaseComObject(oRecordSet);
Hope this helps.

Satish

Remote Desktop "Bypass RD gateway server for local addresses" no longer working in Windows 8

Hi,
After installing windows 8, it seems like the "Bypass RD gateway server for local addresses" is no longer working.
In Windows 7, when the option is checked, I could have the server name set always and the client will automatically detect whether to use the RD gateway or not. For example, from my house, if I am connecting to a computer at my work, which requires
the RD gateway, it will automatically pops up the dialog for authentication method. However, if I connect to a computer in my home network, it will just automatically connects without asking authentication for the RD gateway.
However, after installing windows 8, this does not seem to work as expected anymore. The option is checked but the Windows Security dialog pops up in both situations and so i have to either save the rdp file locally and pin it to the taskbar or switch between
disabling and enabling the RD gateway whenever I need to connect to different machines.
Is this a regression in Windows 8? Is anyone else experiencing the same issue?
Thanks

Another way to resolve this issue for me, beside of configuring RDP to connect directly to server also on unmanaged network, will be to turn the "wifi" subnet in a managed network, as the "wired" subnet is.
The differences between thoses to subnets, dynamically assigned by the same DHCP server, are:
The "wifi" is in a private IP range, the "wired" is in a public IP range
There's an ACL on the "wifi" subnet, not on the "wired"
The next step is to compare frames send/received when on the two networks. Something will likely tell for the network to be managed.
Beside, I'm still searching informations about NLA, which is responsible for setting a nework as managed or not.
Here are some clues:

1st gen ipod Shuffle not updating play count for songs

I've noticed since I updated to the iTunes version 7.2.035 that plugging in and updating the library with my iPod shuffle no longer updates the play count for the songs I've listened to. Is there a known fix for this? Anyone else experiencing the same problem with their 1st gen ipod shuffle (512)?

Well, I have that problem too. My shuffle holds about 125 songs or so, yet I've noticed there are always a good 20 or so songs that won't play, no matter how many times I load them onto the device. I have had that problem since I inherited it from a friend.
My new problem is that every time I plug my iPod into iTunes, it no longer updates the playcount for songs. In other words, if I load a song that I've heard 3 times, hear it twice during the day, and replug in my iPod at night, it used to update that song's playcount in the library to 5, but now they still read 3. It's also failing to update the "date last played" field.
I use those to help make sure that I don't load the same songs over and over again by creating a custom playlist that will comb out songs played in the last few days and have a very high play count. Since these are no longer updating, I've noticed that I keep arriving at work only to find my iPod has the same or similar songs as the day before, and dude, if I wanted that, I'd listen to the radio!

Validation error on retry count for session bean

Hi,
In our weblogic-ejb-jar.xml we have configured a retry count for a specific method on a local session bean. When I click on 'Browse' to select a specific method, it only shows '*' as a possible value. When we type the method name by hand, it shows a red cross next to the input field with the error 'Cannot find method "exampleMethod()" in the ExampleBean's Local interfaces'.
We use EJB 3.0 and OEPE 12.1.1.0.1 with Eclipse 3.7.2
The weblogic-ejb-jar.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>

</weblogic-ejb-jar>The bean looks like this:
@Stateless(mappedName = MappedName.DONNA)
@TransactionAttribute(value = TransactionAttributeType.REQUIRES_NEW)
public class ExampleBean implements Example {
}And the interface:
@Local
public interface Example {
}Does anyone else have this problem?
Thanks.
