I am really new to datapower gateway scripts & i have small requirement.
In datapower newly Gateway script is added from firmware 7.0 onwards. now i am trying to using the GWSript to develop the code to know the domain name and it's state.
here the input is a export.xml file. from that file i need to capture the domain and state of domains and need to be display as a HTML table.
output
If you have any idea about this. Please advise.
You can get the name of the domain from a service variable:
http://www-01.ibm.com/support/knowledgecenter/SS9H2Y_7.2.0/com.ibm.dp.doc/var-service-domain-name_reference.html
Not sure what you mean by 'state' but perhaps this is helpful:
You could interrogate the var://service/system/status/DomainStatus variable
http://www-01.ibm.com/support/knowledgecenter/SS9H2Y_7.2.0/com.ibm.dp.doc/var-service-system-status_reference.html
GatewayScript to get the variables:
var sm = require ('service-metadata');
var domain = sm.getVar('var://service/domain-name');
var domainState = sm.getVar('var://service/system/status/DomainStatus');

I have added a few tables on DynamoDB using the amplify add storage command.
But the table has a suffix that is the environment name (dev, prod, etc).
How can I access the environment name on my NextJS backend so I can suffix the DynamoDB table name on my code ?
Or there is another way to achieve what I want ?
Amplify automatically creates DynamoDB tables (and also AppSync queries, etc) to match your current Amplify environment. When you create a new environment (eg, 'dev'), the Amplify will automatically create duplicate 'prod' tables, that will perform the same as you 'dev' tables. I'm guessing in your case, you won't need to access environment variables.
If you are using AppSync/GraphQL to make calls, then you can use Amplify's built in dynamic env features here: https://docs.amplify.aws/cli-legacy/graphql-transformer/function/#usage
For example, you could set up a custom Lambda function to update your DynamoDB. You could then set up an AppSync call to that Lambda in your schema.graphql file.
There are some cases where you may need to access your environment variables. You can either set them up manually in .env.local, or possibly easier to run a query in your NextJS javascript to determine the current domain:
const origin =
typeof window !== "undefined" && window.location.origin
? window.location.origin
: "";
console.log(origin); // "https://dev.<>.amplifyapp.com"
An better solution would be to follow this Amplify documentation, except I've tried it and it doesn't work.
I get this in the left nav panel. I've explored each one and no sign of the described Environment Variables section:
It describes accessing/updating env vars here, but apparently you can only find/use this feature if you've connected your Amplify app to Github first. (It would have been nice if the docs had clarified this!)

How to use odbs source DSN name from csv file?
(Answer to be expanded with additional info provided - see comments on original question)
While I have never imported a DSN name through a CSV, your saying that it works on your local machine makes me accept that this is at least possible so we'll instead focus on issues with the gateway.
My first impression here as to why this might not be working is simply permissions and visibility.
Having worked with a number of PowerBI Service setups, the issue with an unrecognized ODBC DSN usually falls into the following issues:
Is the DSN setup as a system DSN?
Is the gateway setup as a LocalService Account vs PowerBI Gateway Host Account?
Does which user the gateway is setup under actually have permissions to the directory that the data source (or custom connector) that the connection depends on?
So:
Fairly straight forward: all gateway accessible ODBC sources need to be setup on the gateway host as system DSNs, not user DSNs. See your ODBC Data Source Administrator here:
Confirm the On-Premise Gateway "Logon" User on the gateway's host machine? Generally I recommend going to Windows Services and making sure to use the "Local System account" (to inherit permissions) but just consider this during the next step of checking local permissions.
This applies to anything which is "self-hosted" on the local machine that is the gateway host: Whichever account is hosting the powerbi gateway service must also be given explicit permissions to the local resources needed. For example, if you add a custom connector to the documents directory on the gateway host under your user account - make sure the PowerBI default user has access to that directory and file. I.E. File properties -> Security -> User permission etc.
In my experience, 9/10 times one of these things isn't setup right.
Additional note - every time you upgrade or re-install a powerbi gateway host, you will have to change the service login account and double check all permissions. I don't know why but it overwrites that setting by default disabling all refresh until restored.
Edit:
After further thinking, I believe you will eventually run into the roadblock regardless - PowerBI Service's Gateway Data Source mappings are 1-1. After upload you will get this screen in the dataset settings:
Which requires that the data source has been defined in the PowerBI service's settings:
I don't believe that it is currently possible to make that definition a variably composed string per user's request.
Dsn name can be only static and only string
So say my request url to get all the Users at Location 4 is something like
./Location/Users?locationId=4 or ./Location/Users/4
but we would of course prefer to structure the request url like this:
./Location/4/Users
however, every single AWS help document and help question I can find on here uses the first syntax, so I am unsure how to proceed. It seems like there should be a way to do this, as it is a very common design pattern, but AWS seems to lock you in to only being able to append to the ./Users path instead of being able to prepend the argument.
To be clear, the first request syntax is working, but I'm not sure how to adjust the syntax to a more industry-standard way of doing it since embedding the parameter in the middle of the url instead of at the end would fundamentally change the Amazon Resource Name.
There's probably something simple that I'm missing here though.
Api gateway indeed supports URl like Location/{locationId}/Users. You first need to create locationId as a child resource and then create users as a child resource under that.
Steps
Click Location, and goto actions and click create resource.
fill the details of your new resource
resource name - give a meaningful name
resource path - {locationId}
repeat the same to add Users under LocationId
Postman has been an amazing tool for me, but I have some questions about using variables. In my collection I have 4 tabs/requests.
The first is to get a token that is used in the other three (the token expires after 15 minutes so I have to rerun that request frequently and update the other 3). It needs to be passed in the headers of the other three requests. I'm familiar with the {{variable}} syntax, but I'm not sure how to dynamically set the variable after running the first request.
The second is similar, where I'd like to be able to set a string manually in some central location and use it in all of the requests. For instance, the URL is https://the.api.com/v1/{{someidvalue}}/abc so where can I change that in a single location manually to be reused across the collection?
Thank you!
To change the value based on server response you can use the test feature Postman test script
For exemple
var jsonData = JSON.parse(responseBody);
postman.setEnvironmentVariable("Authorization","Bearer " + jsonData.result.accessToken);
The central location that you are looking for is the enviroment postman manage environments
I am completely new to Amazon Web Services, however, I did get an account and I am able to browse our list of servers. I am trying to create a database backup programmatically using .NET. I have installed AWS for .NET and I have built and run the sample Empty console program.
I can see that I can create an instance of the RDS service with the following line:
AmazonRDS rds = AWSClientFactory.CreateAmazonRDSClient(RegionEndPoint.USEast1);
However, I notice that the rds.CreateDBSnapshot(); needs a request object but I don't see anything like CreateDBSnapshotRequest in the reference .dll, can anyone help with a working example?
Like you said CreateDBSnapshotRequest is the parameter you have to pass to this function.
CreateDBSnapshotRequest is defined in the Amazon.RDS.Model namespace within the AWSSDK.dll assembly (version 1.5.25.0)
Within CreateDBSnapshotRequest you must pass the the DB Instance Identifier (for example mydbinstance-1), that you defined when you invoked the CreateDBInstance (or one of it's related methods) and the identifier for the snapshot you wish to generate (example: my-snapshot-id) for this DB Instance.
edit / example
Well there are a couple ways to achieve this, here's one example - hope it clears up your doubts
using Amazon.RDS;
using Amazon.RDS.Model;
...
...
//gets the credentials from the default configuration
AmazonRDS rdsClient = AWSClientFactory.CreateAmazonRDSClient();
CreateDBSnapshotRequest dbSnapshotRequest = new CreateDBSnapshotRequest();
dbSnapshotRequest.DBInstanceIdentifier = "my-oracle-instance";
dbSnapshotRequest.DBSnapshotIdentifier = "daily-snapshot";
rdsClient.CreateDBSnapshot(dbSnapshotRequest);
Dont't forget that the DB Instance (in the example my-oracle-instance) must exist (duh :) and must be in the available state, like this:
