Max time between log

Hello,
In LabVIEW DSC 7.1 there was the parameter "maximum time between logs" setting in Configure>>Historical menu.
This parameter has been removed in LabVIEW DSC 8.2.
Is there anything I have to do to force the same "maximum time between logs" behaviour in Labview 8.2?
Thanks

Hi !
Look at the answer here.

How to use "Days to keep historical data" & "Maximum time between logs(hh:mm:ss)

Iam using LabVIEW DSC. Values are being logged continously into citadel.
Is it possible to retain data of just one month and delete the earlier data as fresh data is being logged into citadel?
Is it possible to achieve this feature with "Days to keep historical data" & "Maximum time between logs(hh:mm:ss)" options in the history menu of Tag configuration editor ?

Yes, Days to keep historical data does what you are looking for. After the specified number of days, the old data gets overwritten with new data. So, you always have only the specified number of days' of data in Citadel.
Note: You may sometimes see that old data doesn't get overwritten till after a day or so of your setting (depending on how much data is being logged). This is because Citadel logs in "pages" and waits till the current page it's logging to is full before it starts overwriting the old ones.
You do not have to use the 'Max time between logs' option for this. This option forces Citadel to log data every so-many hh:mm:ss regardless of whether or not the data has changed. Note that this is NOT a way to "log data on
demand". Because, this periodic logging of data would change for a particular tag when its data changes. So, even with this setting all data may not get logged at one shot. Anyways, as I said, you do not have to use this setting for what you're trying to do.

I miss the "maximum time between logs" - option

Hello,
with LabVIEW DSC 7.0 I could configure my Citadel Database with an option called "maximum time between logs".
I miss this in LabVIEW DSC 8.2.1.
Where ist it gone?
Thank you
Thomas

That's a good point. I will verify this behavior and report it to our developers if I find the same issue. As a workaround you could use the Database Writing vis (DSC Module >> Historical >> Database Writing). With these vis you can write data to the database programmatically at a rate that you can define by your own
I hope this helps,
Jochen

Determine max differences between times per day

What is the simplest query to determine the max time between date fields per day? In other words we have records being entered all the time to a certain table. I want to watch that table to measure the max time at the end of the day between each record that was entered. I then want to go back historically and look at what the average for max times was.

"logon time" between USR41 and security audit log

Dear colleagues,
I got a following question from customer for security audit reason.
> 'Logon date' and 'Logon time' values stored in table USR41 are exactly same as
> logon history of Security Audit Log(Tr-cd:SM20)?
Table:USR41 saves 'logon date' and 'logon time' when user logs on to SAP System from SAP GUI.
And the Security Audit Log(Tr-cd:SM20) can save user's logon history;
at the time when user logged on, the security audit log is recorded .
I tried to check SAP GUI logon program:SAPMSYST several ways, however,
I could not check it because the program is protected even for read access.
I want to know about specification of "logon time" between USR41 and security audit log,
or about how to look into the program:SAPMSYST and debug it.
Thank you.
Best Regards.

Hi,
If you configure Security Audit you can achieve your goals...
1-Audit the employees how access the screens, tables, data...etc
Answer : Option 1 & 3
2-Audit all changes by all users to the data
Answer : Option 1 & 3
3-Keep the data up to one month
Answer: No such settings, but you can define maximum log size.
4-Log retention period can be defined.
Answer: No !.. but you can define maximum log size.
SM19/SM20 Options:
1-Dialog logon
You can check how many users logged in and at what time
2-RFC login/call
Same as above you can check RFC logins
3-Transaction/report start
You can see which report or transaction are executed and at what time
(It will help you to analyise unauthorized data change. Transactions/report can give you an idea, what data has been changed. So you can see who changed the data)
4-User master change
(You can see user master changes log with this option)
5-System/Other events
(System error can be logged using this option)
Hope, it clear the things...
Regards.

When using historical datalogging, is it possible to hide the elapsed time between tag updates when viewing on a graph?

When my process stops, I am reading an array of tags(datapoints) and writing the max and average to memory tags for data logging. However, when viewing the data, the elapsed time between cycles spreads the data out unevenly. It could be 90 seconds between cycles or maybe two hours or longer. Is there a way to convert the time axis data to be just consecutive datapoints?? It would be like logging data based on a particular condition happening rather than time-based trending. Should I try to use the data set logger examples instead?? I would prefer to use the built-in datalogging features rather than writing to databases.

You could export your data to a spreadsheet file and then actually write then again in a second database using this example program in the devzone
http://zone.ni.com/devzone/conceptd.nsf/webmain/5A921A403438390F86256B9700809A53?opendocument
Using this program (if you don't want to modify it, which would take a reasonable amount of time specially if you are not familiar with VI-Based Server) You would have to generate a collum in your spreadsheet file to be the timestamp, it would be a artificial timestamp.
What you could do in your application is to first save the data to file and then read from file, substitute the collum timestamp for the "artificial one" and then write it to the database, again, with that you would not need to modify this program.
However if you have the time and is willing to work with VI-based server you could try to modify the example program to be adapted for your purposes.
I hope it helps
Good Luck

Getting error while taking MAX DB trans log backup.

Hi,
I am getting error while taking trans log backup of Maxdb database for archived log through data protector as below,
[Critical] From: OB2BAR_SAPDBBAR@ttcmaxdb "MAX" Time: 08/19/10 02:10:41
Unable to back up archive logs: no autolog medium found in media list
But i am able to take complete data and incremental backup through data protector.
I have already enabled the autolog for MAX DB database and it is writing that log file directly to HP-UX file system. Now i want to take backup of this archived log backup through data protector i.e. through trans log backup. So that the archived log which is on the file system after trans log backup completed will delete the archived logs in filesystem. So that i don;t have to manually delete the archived logs from file system.
Thanks,
Subba

Hi Lars,
Thanks for the reply...
Now i am able to take archive log backup but the problem is i can take only one archive file backup. Not multiple arhive log files generated by autolog at filesystem i.e /sapdb/MAX/saparch.
I have enabled autolog and it is putting auto log file at unix directory i.e. /sapdb/MAX/saparch
And then i am using the DataProtector 6.11 with trans log backup to backup the archived files in /sapdb/MAX/saparch. When i start the trans backup session through data protector it uses the archive stage command as "archive_stage BACKDP-Archive LOGBackup NOVERIFY REMOVE" If /sapdb/MAX/saparch has only one archive file it will backup and remove the file successfully. But if /sapdb/MAX/saparch has multiple archive files it gives an error as below,

The Job Failed Due to MAX-Time at ODS Activation Step

Hi
I'm getting these errors "The Job Failed Due to MAX-Time at ODS Activation Step" and
"Max-time Failure"
How to resolve this failure?

Hi ,
You can check the ODs activation logs in ODs batch montior >> click on taht job >>> job log
for this first you check in sm37 how many jobs are running if there are many otehr long running jobs then . the ODs activation will happen very slowly as the system is overloaded .. due to the long running jobs ..this causes the poor performance of system ..
for checking the performance of system .. you first check the lock waits in ST04..and check wether they are progressing or nt ..
check sm66 .. for the no of process running on system ..
check st22 >> for short dumps ..
check Os07> to check the cpu idle tiem if its less tehn 20% . then it means the cpu is overlaoded .
check sm21 ...
check the table space avilable in st04..
see if the system is overlaoded then the ODS wont get enough work process to create the backgorund jobs for that like(Bi_BCTL*)..jobs .the updation will happen but very slowly ..
in this case you can kill few long running jobs which are not important .. and kill few ODs activations also ..
Dont run 23 ODs activation all at a time .. run some of them at a time ..
And as for checking the key points for data loading is check st22,cehck job in R/3 , check sm58 for trfc,check sm59 for Rfc connections

Understanding Time Machine logs

I posted a similar question earlier, but retracted it when I realized I didn't know enough about how Time Machine worked, and hard links in particular. Having done my research, I still have my questions. Looking at the log below:

I have several questions.
The first is why Time Machine is backing up so much data. As you can see, on Dec 22 at 13:59:39 Time Machine backed up 1.7 GB of data. I know for a fact that I did not add anywhere near 1.7 GB of data to my machine in the time between the last backup and that one. Where did Time Machine get that number? Is it backing up files I'm not aware of but which need backing up, like system files or the swap files from /private/var/vm?
Second, in the list are two drives, Wintermoot and Feezmoe. Wintermoot is my main drive, while Feezmoe is a storage drive. Because of this, the contents of Feezmoe do not change very often. However, Time Machine always seems to back up the same amount of data from both, even when nothing has been added to Feezmoe. Is Time Machine actually wasting space in this way, or is there something I don't know about how Time Machine presents information in the log which is confusing me?
Third, there always seem to be two backup cycles for each timestamp. Is the second cycle perhaps related to the Spotlight database, or do I have a setting in my Time Machine set up which needs to be changed?
I want to say that, overall, I am delighted with Time Machine's performance, but I want to make sure it is working properly and that I have set it up properly.

Is there actually a problem, ie is your backup folder growing too quickly?
I have just looked at my TM log and in the same line as you are quoting my latest backup said 214.7 MB. Now my entire backup folder is not much greater than 40 MB so the numbers being produced by the log are clearly wrong. Could be the log is confused by the multiple hard links used by TM but I'm guessing.
TM seems to working fine for me (not that I've restored anything hugely complicated to date).

Elapsed time between 2 points

Hello,
I'm trying to measure the time between 2 datapoints.
When the data acquirement begins the time should be saved and when the signal reaches 90% of it's max.
Those 2 times then get subtracted and then you have the elapsed time.
But I'm not quite sure how to do this... I was thinking with flat sequences.
Solved!
Go to Solution.

Are you constantly capturing a signal? What is your sample rate?
What you need to do first to capture the signal. You can then find the maximum value with the Array Max & Min function. Calculate your 90% (0.9*Max). Search the data until your get greater or equal to the 90% mark. Get that sampling number. Your time is then number of samples to the 90% mark divided by the sample rate (in Samples/Second).

SQL Command to select MAX(date) & Max(time)

My am having a really hard time getting a sql command to return data with the max(date) & max(time) combination. I think I need a sub query but can not figure it out. I have looked all over the internet but still don't understand it. Below is my command which returns the max date & max time but they are not from the same row of data. Please help.
SELECT "labor"."order-no", "labor"."oper-no", MAX("labor"."end-date") AS myDate, Max("labor"."end-time") AS myTime
FROM   "E940LIVE"."PUB"."tm-log" "labor"
WHERE "labor"."order-no"='73153-bc' AND "labor"."company"='01'
GROUP BY "labor"."order-no", "labor"."oper-no"

Progress does not support the DATEADD function. Waht if I forget the number is time and look at it just as a number. Here is my data and what I have tried (again I don't understand the multiple select concept yet).
Data
oper-no   end-date    end-time

Message: "The database structure has been modified" every time I log to SAP

Hello,
"The database structure has been modified. In order to resume this process, all open windows will be closed". Every time I log to one of my companies in SAP Business One this message appears.
I haven't installed any new addons and made no changes in database structure (and any other user hasn't done any changes), but this message appears always when I log to company for the first time (when I try to log on another user or log to another company there is no message). Can anyone help me with this problem?
Best regards

Every time I log onto firefox it comes up in dutch. This also affects everything as it is all in dutch...why? I am english!

For the last couple of weeks every time I log onto firefox it is in Dutch. Someone is accessing my facebook account from Amsterdam and that also appears in Dutch. Hopefully that one has been resolved but it is a big worry. I did nothing to change my login to firefox so why is this happening as it is a major irritation!

You can find the English Firefox version here:
* Firefox 3.6: http://www.mozilla.com/en-US/firefox/all-older.html
* Firefox 4.0: http://www.mozilla.com/en-US/firefox/all.html

Every time I want to log in to my Hotmail account I have to type my password over again, and every time I log in I try to save my password. I have tried hundreds of times, but it seems impossible. What am I doing wrong?

When A person want to log in to a hotmail account to read or send an E-mail, one have to enter the e-mail adress and password. There is also a small square you can mark i you want Firefox to save your password so that you don't have to enter password every time you log in to the e-mail account (in this case hotmail)
Every time I log in to hotmail I mark the square so that Frefox will save my password, but my password has never been saved. I'm so tired of always having to enter my password, over and over again.
What do I do wrong? How can I solve tis problem?

Try restart the operating system in '''[http://en.wikipedia.org/wiki/Safe_mode safe mode with Networking]'''. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: [http://windows.microsoft.com/en-us/windows-8/windows-startup-settings-including-safe-mode Windows 8], [http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7 Windows 7], [http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-vista Windows Vista], [http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx?mfr=true" Windows XP], [http://support.apple.com/kb/ht1564 OSX]
