From device, the information is sent to the c8y platform. The parameter values are in HEX and we convert it to Integer or string using a Event processing script. The converted values are stored in the database table.
But we are facing a challenge in displaying the values in the explorer graph in the cockpit application from the database table.
It will be very helpful if you could provide any sample code to display a graph using the event processing script.
#Name("createdTempSchema") create schema UplinkUpdateEvent (msg string,time
Date,msgid string);
#Name("UplinkUpdateEvent") insert into UplinkUpdateEvent select
event.event.source.value as msgid,
event.event.time as time,
getString(event, "objectResourceValue") as msg
from EventCreated event
where event.event.type.startsWith("c8y_UpLin");
#Name("createUplinkAlarm") insert into CreateAlarm select "c8y_UpLinkMsgAlarm" as type,
u.time as time,u.msgid as source,
"CRITICAL" as severity,
"ACTIVE" as status,
msg as text from UplinkUpdateEvent u
where u.msg is not null;

I am trying to send an alert if there is no records in destination table after copy activity is completed. right now I am try with lookup activity along with if activity but getting this below error
Operation on target Alert If no records in activity ts failed: The function 'int' was invoked with a parameter that is not valid. The value cannot be converted to the target type
You can do this more simple.
Add an variable to you pipeline, varError.
In your lookup, add a select count(*) from your_table
Add an activity "Set variable" where you set the variable to
#string(div(100, int(activity('IsRecordExist').output.firstrow.yourColumn)))
This will do an device by 0 if no values are copied, and cause the pipeline to fail.
You can then sett up a monitor for pipeline failed that sends you an alert.
I've recently set some traces and extended events up and running in SQL on our new virtual server to show the access that users have to each database and whether they have logged in recently, and have set the file to save as a physical file on the server rather than writing to a SQL table to save resource. I've set the traces as jobs running at 8am each morning with a 12-hour delay so we can record as much information as possible.
Our IT department ideally don't want anything other than the OS on the C drive of the virtual server, so I'd like to be able to write the trace from my SQL script either to a different partition or to another server altogether.
I have attempted to insert a direct path to a different server within my code and have entered a different partition to C, however unless I write the trace/extended event files to the C drive I get an error message.

ADD TARGET package0.asynchronous_file_target (
SET FILENAME = N'\\SERVER1\testFolder\LoginTrace.xel',
METADATAFILE = N'\\SERVER1\testFolder\LoginTrace.xem' );
The error I receive is this:
Msg 25641, Level 16, State 0, Line 6
For target, "package0.asynchronous_file_target", the parameter "filename" passed is invalid. Target parameter at index 0 is invalid
If I change it to another partition rather than a different server:
SET FILENAME = N'D:\Traces\LoginTrace\LoginTrace.xel',
METADATAFILE = N'D:\Traces\LoginTrace\LoginTrace.xem' );
SQL server states that the command completed successfully, but the file isn't written to the partition.
Any ideas please as to what I can do to write the files to another partition or server?
I have the following lines in my ODBC Log :
(Scenario: pgAdmin4, using PostgreSQL server through ODBC32 in another application named System Administration)
System Admi 6a0-6f8 ENTER SQLExecDirect
HSTMT 0x00630718
UCHAR * 0x036B29C0 [ 63] "create table new (npages integer, ifnds integer, ifnid integer)"
SDWORD 63
I need to know the meaning of HSTMT, UCHAR* and SDWORD. What do those numbers next to them mean ?
From the article Everything You Want To Know About ODBC Tracing
In the trace log, you’ll see the data type of the handle being
SQLHANDLE, HENV / SQLHENV, HDBC / SQLHDBC, HSTMT / SQLHSTMT. This
value is unique to the particular series of items being called. You
can search in the trace log for this handle number and each call made
on the handle will be shown. This allows you to pick out only the
calls in the trace log that are relevant to your error message. Keep
in mind, some applications may create multiple handles. For example,
your application may execute three statements consecutively with each
residing on a different statement handle.
For examples and more details follow the next nice document:-
How to read an ODBC trace file.rtf
This is a record of ODBC tracing
There was a procedure "SQLExecDirect" with statement handle 0x00630718, text parameter (passed as pointer) is "create table ..." and last parameter is size of text (passed as word type). See related reply in MSDOC.
HSTMT,UCHAR, SDWORDS are data types used by C, C++ MS Windows API.
Trying to use the mv.NET by bluefinity tools. Made some integration packages with it for importing data from a d3 multi-value database into MS SQL 2012 but seem to be having some trouble with the mapping.
For the VOYAGES table have some commentX fields in the D3 application that are acting quite unwieldy and the INSERT fails after a certain number of rows with the following message
>Error: 0xC0047062 at INSERT, mvNET Source[354]: System.Exception: Error #8: dataReader[0] = LTPAC002 ci.BufferColumnIndex = 52, ci.ColumnName = COMMGROUP(Error #8: dataReader[0] = LTPAC002 ci.BufferColumnIndex = 52, ci.ColumnName = COMMGROUP(The value is too large to fit in the column data area of the buffer.))

Error: 0xC0047038 at INSERT, SSIS.Pipeline: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED.The PrimeOutput method on mvNET Source returned error code 0x80131500.The component returned a failure code when the pipeline engine called PrimeOutput().The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.There may be error messages posted before this with more information about the failure.
The value is too large to fit in the column data area of the buffer. -> tried changing the input / outputs types but can't seem to get it right.
In the SQL table the columns are of type ntext.
In the .dtsx job the data type for the columns are of type Unicode String [DT_WSTR] with length 4000 , I guess these are auto-detected.
The import worked for other D3 files like this not sure why it fails for these comment fields.
Running the query on the mv.NET Data Manager ( on the d3 server) times out after 240 seconds so maybe this is the underlying issue?
Any ideas how to proceed? Thank you ~
Most like reason is column COMMGROUP does not have correct data type or some record in source do not fit in output type
To find error record (causing) you have to use on redirect row (property of component failing component ) and get the result set in some txt.csv /or tsv file .
then check data
The exception is being thrown from mv.NET so I suggest you call (or ask your reseller) to call Bluefinity support and ask them about this. You're paying for support, might as well use it. Those programs shouldn't be allowed to throw exceptions like that.
D3 doesn't export Unicode, that might be one issue. But if the Data Manager times-out then I suspect something is wrong in the connectivity into D3. Open a Connection Monitor from the Session Monitor and watch the connection when you make the request. I'm guessing it's either hanging or more probably it's falling into BASIC Debug.
Make sure all D3-side programs related to this are either all Flash-compiled, or all Not Flashed. Your app code will fall into Debug if it's not Flashed but MVNET.BP is.
If it's your program that's in Debug, fix it. If you're not sure which program it is, LIST-RUNTIME-ERRORS in DM.
If it's a MVNET.BP program, again work with Bluefinity. If you are using MVSP for connectivity then the Connection Monitor may be useless, you'll need to change that to an IP (Telnet) connection to see the raw data exchange.
I have a question about powercenter message code: RR-4035. I have a mapping in which i am using a sql override query, this error is in sql override. This mapping is failing with an error,
'[IBM][CLI DRIVER]CLIO113E SQLSTATE 22007:An invalid datetime format
was detected, that is an invalid string representation or value was
specified'.
> Database driver error:

and s.employee_record_term_dt>sysdate;
native error code= -99999
I have tried everything, my previous mappings have run fine with the same datetime formats but this one is failing. One thing i have noticed is that if i remove all the transformations in between the source qualifier and target the mapping succeeds and data gets loaded to target, but as soon as i put any lookups or expressions between source qualifier and target except a pass through expression, the mapping fails again.
Any suggestion, any help regarding this is appreciated.
We've seen this error occurring when SELECTing from a table with a timestamp column via the IBM Data Server ODBC/CLI driver. It only happened on one Windows machine and we were able to make the error disappear by changing the regional setting main selection from Israel to USA.
While not tested yet, it may be that the IBM DB2 ODBC configuration option DateTimeStringFormat or the attributes SQL_ATTR_DATE_FMT and SQL_ATTR_TIME_FMT can be used to force a specific format (such as JIS).
