Error Log information in VB Script while processing - asp.net

I am having an VBScript files which runs by many instance of jobs. I need to log the error information if any error occurs in the script processing. If i maintain a log file then how can i differentiate the log file for each instances (around 10 simultaneous instances) of vb script calling.
I dont go for any db logging.
Please suggest some good ways.

I would use the same log file for all instances. I would then have each instance create a GUID:
http://www.microsoft.com/technet/scriptcenter/resources/qanda/feb05/hey0221.mspx
When an error is logged by an instance, it uses the GUID to identify itself. This way it shouldn't matter if you have 10 or 50 instances, they will be unique in logging and you won't have a ton of log files everywhere.

Artifactory Users Management not loading

I'm trying to open the Artifactory Users Management page, following the Admin->Security->Users tab.
Then I'm getting the following error:
Any idea of what might be causing it? Also, which log I can check this? Couldn't find anything yet.
The server error generally indicates there is problem fetching the user details from Artifactory. This can happen due to any of the following reasons:
when you have a high volume of users and the request is timing out.
There is a chance that you might have created a username with a
special character which is not allowed (using the REST method or some
other method)
There is an issue with the backend database
And the best place to troubleshoot is to first check the request log a good valid entry looks like below:
20200715164402|104|REQUEST|165.225.104.49|admin|GET|/ui/users|HTTP/1.1|200|0
Next check the artifactory.log file for java stack or check catalina.out under tomcat/logs directory.

BizTalk 2006 Event Log Warnings - Cannot insert duplicate key row in object 'dta_MessageFieldValues' with unique index 'IX_MessageFieldValues'

We have been seeing the following 'warnings' in the event log of our BizTalk
machine since upgrading to BTS 2006. They seem to occur
randomly 6 or 8 times per day.
Does anyone know what this means and what needs to be done to clear it up?
we have only one BizTalk server which is running on only one machine.
I am new to BizTalk, so I am unable to find how many tracking host instances running for BizTalk server. Also, can you please let me know that we can configure only one instance for one server/machine?
Source: BAM EventBus Service
Event: 5
Warning Details:
Execute batch error. Exception information: TDDS failed to batch execution
of streams. SQLServer: bizprod, Database: BizTalkDTADb.Cannot insert
duplicate key row in object 'dta_MessageFieldValues' with unique index
'IX_MessageFieldValues'.
The statement has been terminated..
I see you got a partial answer in your MSDN Post
go to BizTalk Admin Console ,check in Platform Settings -> Hosts, in the list of hosts on the right, confirm that only a single Host has the Tracking column marked as Yes.
As to your other question. Yes you can run a Single Host Instance on a Single Server. Although when your server starts to come under a bit of load you may want to consider setting up some more so you can balance the workload better.

run oracle reports from pl/sql procedure

I'm refactoring a very old reports generating function in an ORACLE web application. It used JavaScript to construct a URL, sending to the reports server to run a reports. What I want to do is processing it in the database, in PL/SQL procedures(invoked through mod_pl/SQL). I tried to use utl_http.begin_request to do that, but sometimes when the output file is large(PDF format, about 20 pages, 1.5M), I received an error:
ORA-29259: end-of-input reached.
The test codes for sending requests are quite simple:
--------upgraded 2013/08/27----------------------------------------------------------
UTL_HTTP.set_transfer_timeout(1000);
--some params setting....
myIdent := SRW.RUN_REPORT(myPlist); --here raise the exception(ORA-29273:request_failed; ORA-29259: end-of-input reached.) and procedure stoped.
r_stat := SRW.report_status(myIdent,myPlist);
#ThinkJet, Thanks for your help.
I logon the report server, found that the report still running after I got this exception in my program, and finally finished succefully.I tested for many times, and found everytime I got the exception just 5 minutes after I started request,no matter what kind of reports I was running and what size it was (sure, all big size,running for over 5mins).I'm wondering if it's something about configuration on oracle application server?
Does anyone have idea about this? Many Thanks.
ORA-29259 while SRW.RUN_REPORT
is ias 10g , this is cause by httpd.conf timeout parameter configuration
just
1.edit $ORACLE_HOME /Apache/Apache/conf/httpd.conf
change "Timeout" great than your report running time
2.restart http server and test it.
opmnctl restartproc ias-component=HTTP_Server
It take a time on Oracle Reports side to produce a big reports so a timeouts can occur sometime. Try to increase timeout with utl_http.set_ransfer_timeout procedure before originate a request and look if it helps.

Just started getting AIR SQLite Error 3182 Disk I/O error occurred

We have a new beta version of our software with some changes, but not around our database layer.
We've just started getting Error 3128 reported in our server logs. It seems that once it happens, it happens for as long as the app is open. The part of the code where it is most apparent is where we log data every second via SQLite. We've generated 47k errors on our server this month alone.
3128 Disk I/O error occurred. Indicates that an operation could not be completed because of a disk I/O error. This can happen if the runtime is attempting to delete a temporary file and another program (such as a virus protection application) is holding a lock on the file. This can also happen if the runtime is attempting to write data to a file and the data can't be written.
I don't know what could be causing this error. Maybe an anti-virus program? Maybe our app is getting confused and writing data on top of each other? We're using async connections.
It's causing lots of issues and we're at a loss. It has happened in our older version, but maybe 100 times in a month rather than 47,000 times. Either way I'd like to make it happen "0" times.
Possible solution: Exception Message: Some kind of disk I/O error occurred
Summary: There is probably not a problem with the database but a problem creating (or deleting) the temporary file once the database is opened. AIR may have permissions to the database, but not to create or delete files in the directory.
One answer that has worked for me is to use the PRAGMA statement to set the journal_mode value to something other than DELETE. You do this by issuing a PRAGMA statement in the same way you would issue a query statement.
PRAGMA journal_mode = OFF
Unfortunately, if the application crashes in the middle of a transaction when the OFF journaling mode is set, then the database file will very likely go corrupt.1.
1 http://www.sqlite.org/pragma.html#pragma_journal_mode
The solution was to make sure database delete, update, insert only happened one at at time by wrapping a little wrapper. On top of that, we had to watch for error 3128 and retry. I think this is because we have a trigger running that could lock the database after we inserted data.

Issue running ASPX page using Scheduled Task

I have a scheduled task set up to run Scan.aspx every 3 minutes in IE7. Scan.aspx reads data from 10 files in sequence. These files are constantly being updated. The values from the file are inserted into a database.
Sporadically, the value being read is truncated or distorted. For example, if the value in the file was "Hello World", random entries such as "Hello W", "Hel", etc. will be in the database. The timestamps on these entries appear completely random. Sometimes at 1:00 am, sometimes at 3:30 am. And some nights, this doesn't occur at all.
I'm unable to reproduce this issue when I debug the code. So I know under "normal" circumstances, the code executes correctly.
UPDATE:
Here is the aspx codebehind (in Page_Load) to read a text file (this is called for each of the 10 text files):
Dim filename As String = location
If File.Exists(filename) Then
Using MyParser As New FileIO.TextFieldParser(filename)
MyParser.TextFieldType = FileIO.FieldType.Delimited
MyParser.SetDelimiters("~")
Dim currentrow As String()
Dim valueA, valueB As String
While Not MyParser.EndOfData
Try
currentrow = MyParser.ReadFields()
valueA= currentrow(0).ToUpper
valueB = currentrow(1).ToUpper
//insert values as record into DB if does not exist already
Catch ex As Exception
End Try
End While
End Using
End If
Any ideas why this might cause issues when running multiple times throughout the day (via scheduled task)?
First implement a Logger such as Log4Net in your ASP.NET solution and Log method entry and exit points in your Scan.aspx as well as your method for updating the DB. There is a chance this may provide some hint of what is going on. You should also check the System Event Log to see if any other event is associated with your failed DB entries.
ASP.NET is not the best thing for this scenario especially when paired with a Windows scheduled task; this is not a robust design. A more robust system would run on a timer inside a Windows-Service-Application. Your code for reading the files and updating to the DB could be ported across. If you have access to the server and can install a Windows Service, make sure you also add Logging to the Windows Service too!

Regarding your follow up comment about the apparent random entries that sometimes occur at 1am and 3.30am: you should:
Investigate the IIS Log for the site when these occur and find out what hit(visited) the page at that time.
Check if there is an indexing service on the server which is visiting your aspx page.
Check if Anti-Virus software is installed and ascertain if this is visiting your aspx page or impacting the Asp.Net cache; this can cause compilation issues such as file-locks on the aspnet page in the aspnet cache; (a scenario for aspnet websites as opposed to aspnet web applications) which could give weird behavior.
Find out if the truncated entries coincide with the time that the files are updated: cross reference your db entries timestamp or logger timestamp with the time the files are updated.
Update your logger to log the entire contents of the file being read to verify you've not got a 'junk-in > junk-out' scenario. Be careful with diskspace on the server by running this for one night.
Find out when the App-Pool that your web app runs under is recycled and cross reference this with the time of your truncated entries; you can do this with web.config only via ASP.NET Health Monitoring.
Your code is written with a 'try catch' that will bury errors. If you are not going to do something useful with your caught error then do not catch it. Handle your edge cases in code, not a try catch.
See this try-catch question on this site.
