I have one item extracted from a JMX interrogation and I want to compare it against another one extracted from a database. These values shouldn't be equal but first one should contain/include the second - if not then I need an alert.
Obviously I tried with str() function but this one doesn't accept an {item.last} as parameter for the V string:
{node1:ITEM1.str({node2:ITEM2.last()})}=0
Any other idea?
That is currently not possible with the built-in functionality. While it might be possible in Zabbix 3.4, that is not fully clear yet. Please also note that only numeric values can be compared in the Zabbix trigger expressions.

I have a Set Variable activity which uses the logic:
#range(int(pipeline().parameters.start),int(pipeline().parameters.end))
It is wierd that I cant find any logic in documents where I can mention a step so that I can generate few numbers as shown below
1,3,5,7,9,...
Is there work around to it, other than introducin a new parameter that is equal to step and generate next number using logic last = last+step.
It is possible to do this using the Filter activity and the range function. Use the range function to generate all numbers and then the Filter condition with mod to get odd numbers, ie
Property
Value
Items
#range(1,10)
Condition
#equals(mod(item(),2),1)
A screenprint of the results:
The other way to do it would be just use a Lookup activity and query a numbers table.
I agree with you that it's a shame range does not have a step argument, and that generally the ADF expression language isn't a bit more fully featured.
I am trying to pull data from DB2 via informatica, I have a SQ query that pulls few fields based on joins for 4 different tables.
When I run the query directly in the database, it returns the expected result, however when I run it in informatica and run a debugger, I see something else.
Please note all the columns data perfectly match, except one single column.
Weird thing is, this is a calculated field from the table based on a case statement:
CASE WHEN Column1='3' THEN 'N' ELSE 'Y' END.
Since this is a calculated field with a length of one string, I have connected from the source to SQ from one of the sources having 1 character length.
This returns 'Y' when executed in the database, the same query when I copy paste in SQ of information and run it, I get a data 'E', and this data can never be possible as I expect only a N or a Y. I have verified the column order, that its in the right place. This is very strange, is something going wrong because of the CASE Statement?
Save yourself the hassle, put an expression transformation after tge source qualifier and calculate, port value there then forget about it
I think i got the issue. We use Informatica PowerExchange to connect to a as400 system(DB2), and it seems that when we are trying to set a flag information in AS400, and pass it to informatica via PowerExchange, it converts it to binary, and to solve this, there needs to be an entry in the PowerExchange configuration file.
Unfortunately, i myself was not aware that it could be related to PowerExchange instead of powercenter itself.!!
Thanks for your assistance! Below is the KB about it.

I want to execute some subjob if the previously processed number of rows are greater than N. To do this, i'm using the following configuration:
tFixedFlowInput have some rows.
tAggregateRow uses the count function and outputs one row with the number.
tSetGlobalVar then stores this value into a global var that I can check in the Run If connector (In this case, (Integer)globalMap.get("tSetGlobalVar_1") > 3 ).
tMsgBox then shows if the condition is true.
What I would like is to do the same, but in a more elegant way, using the minimum components required. I would like to connect tAggregateRow with the Run If connector directly (or even tFixedFlow) with tMsgBox, but I haven't found a way to refer to the number of rows previously processed without using the output row2.count variable.
How could I do something like this?
What should I put in the If condition to refer to the tAggregateRow operation result without connecting it to another meaningless component like exposed at the beginning?
for any talend component look under outline tab under the left side workspace pane at the bottom. this lists down the properties available via global variables for that component. Some properties like count of records inserted by output components are only available once the component is executed completely (After).
for your case you can try directly using ((Integer)globalMap.get("tFixedFlowInput_1_NB_LINE")) which gives number of lines (after) given by tFixedFlowInput.
I am currently working on a job something like this
The design is to,extract some data from customers,(say first name,last name) to one excel file,other data (say address) is to goto other excel file,i added a identity to tMap Numeric("s1",1,1) but it is starting from 1,3,5,7,9,11,13.... and on other excel it getting 2,4,6,8,10,12,...
but i need both excel to have same identity 1,2,3,4,5,6,....N
so that i can map the records
so can somebody guide me on this?
edit:
The autoincrement returns 1,2,3,4,5,6,... this is fine when thers only one tMap component in the job,but not similar when 2 tMaps are used ?
This is because the numeric sequence is static. Since you have only one sequence called "s1", it will be incremented twice at every iteration (one time for each tMap it's invoked in).
Just use some unique labels (ie. "s1" and "s2") to force the use of two independent sequences, thus the solution of your problem.
In an XmlData column in SQL Server 2008 that has no schema assigned to it, how can I pull the first item at a particular node level? For example, I have:
SELECT
XmlData.value('//*/*[1]','NVARCHAR(6)')
FROM table
where XmlData.Exist('//*/*[1]') = 1
I assume this does not work because if there are multiple nodes with different names at the 2nd level, the first of each of those could be returned (and the value() requires that a singleton be selected.
Since I don't know what the names of any nodes will be, is there a way to always select whatever the first node is at the 2nd level?
I found the answer by chaining Xquery .query() and .value()
XMLDATA.query('//*/*[1]').value('.[1]','NVARCHAR(6)')
This returns the value of the first node and works perfectly for my needs.
