We have a requirement to migrate Oracle 19c hosted on RHEL to Azure managed PostgreSQL. There are 2 options in Azure - 1) Single Server and 2) Flexible server
Single server installs PostgreSQL on windows while Flexible server uses linux. Besides the known in-compatibilities b/w Oracle and PostgreSQL, is there any thing additional to be considered while migrating from a Linux based DB (Oracle) to Windows based DB (Azure PostgreSQL - Single Server).
As per checking "NLS_DATABASE_PARAMETERS" in Oracle DB, I can see below parameters -
NLS_CHARACTERSET AL32UTF8
NLS_SORT BINARY
NLS_COMP BINARY
As per Azure postgresql single server documentation -
lc_collate English_United States.1252
lc_ctype English_United States.1252
lc_messages English_United States.1252
lc_monetary English_United States.1252
lc_numeric English_United States.1252
lc_time English_United States.1252
Is there anything specific to check to ensure seamless migration mainly w.r.t diff hosting environments (Linux Vs Windows)?

I've installed a Strapi application using Digital Ocean's App Platform. I'm also using a managed Postgres database. I can deploy with production configurations, however, Strapi is still creating and using the default sqlite database.
I followed Strapi's deployment docs here: https://docs.strapi.io/developer-docs/latest/setup-deployment-guides/deployment/hosting-guides/digitalocean-app-platform.html#add-a-managed-database
I have set the /config/env/production/database.js and /config/env/production/server.js files. In the console log when the application is being built, it also confirms that it's being run in production mode. I'm not sure why it's ignoring the database.js file though for postgres.
You can try to explicitly set NODE_ENV=production for the container/app's environment.
Oracle environment:
Guest OS: centos7 (Installed in a VMWARE)
version: Release 12.2.0.1.0 Production
Informatica Power Center:
Downloaded site: https://edelivery.oracle.com/osdc/faces/SoftwareDelivery
Software: Oracle Business Intelligence Data Warehouse Administration Console and Informatica PowerCenter
version: 9.5.1
Host OS: windows 10
While installing, informatica is asking to connect to the oracle user. So I created a user and granted dba to it. Even though I provided correct database address, Informatica test connection is failing.
But, with the same config details I can able to connect DB through SQL developer(Version: 19.2.0.206.2117) which was installed on windows (host OS).
So many possibilities, sql developer is running on your local windows client picking up your local tnsnames.ora to resolve the db connection against and with firewalls opened between your local windows client and the database. On your centos server, the Informatica install will resolve against the tnsnames.ora there which may not have an entry for the sid you're trying to hit and even then it will also only find its local tnsnames.ora file if the user doing the install has ORACLE_HOME correctly set in their profile. Not to mention firewalls and networking between the centos machine and the db may not be open.
I am a dot net developer.I am using azure students subscription. I am running a windows service app which compile cpp file, run and collect output and store in database. It uses mingw for compiling. the software hosted in a windows vm. But windows vm cost for student but container instance does'nt.Now I want to run windows server core on azure container and host the service app with remote desktop in windows server core . Is it possible? if possible what is the procedure?
Yes, now you can install Windows Server 2016 Datacenter - Server Core:

how to deploy oracle application express ( APEX ) in windows server ?
any one know about the answer for this question.
you can install Oracle Apex on windows server in the following 2 ways:
If you already have a central database server. You have to install a Java based application server such as: Tomcat, Glassfish or commercial as Weblogic. Then install Oracle Rest Data Services as Apex Integrator. I recommend that you read the following article: https://oracle-base.com/articles/misc/oracle-rest-data-services-ords-installation-on-tomcat
As a second option you would have to install the oracle database in any of its editions for windows platforms and later Install or configure Oracle Application Express (APEX) preferable version 5 or later. you can follow the following link: https://oracle-base.com/articles/misc/oracle-application-express-apex-5-0-installation.
I hope I can be of your help.
Greetings.
I'm limited to what applications I can deploy in my environment, however, standard WAR files are usually not a problem.
Can carbon 4.1.0 run as a web app?
This link describes how it can be done for carbon 3.2.2. Are these steps still valid for 4.1.0?
According to the answer in this link some functionality is limited in webapp mode for 3.2.2. What functionality is limited if 4.1.0 is deployed in webapp mode?
EDIT:
A webapp-mode folder is available in $CARBON_HOME
C:\Users\snowc\Desktop\wso2carbon-4.1.0>type webapp-mode\README.txt
Running WSO2 Carbon in Webapp mode
-------------------------------------
Standalone mode is the recommended way of running All WSO2 Carbon products. However you have the
option of running WSO2 Carbon products in Webapp mode (hosted as a web-app in an application
server).
1. The 'WEB-INF' directory contains the webapp archive
2. The 'bundles' directory contains the additional jars that needs, during the web-app mode
deployment.
Please refer the WSO2 Carbon documentation for step-by-step guide on web-app mode deployment of the
product.
"Can carbon 4.1.0 run as a web app?"
No, we stopped supporting webapp deployment in later 4.x.x carbon versions
