Classes in TypeScript

12. November 2017 Nagnath M. Kendre Articles, Scripts, Typescript (0)

TypeScript classes 

TypeScript extends JavaScript classes to include type parameters, implements clauses, accessibility modifiers, member variable declarations, and parameter property declarations in constructors.

In following example created class employee with filed “fullname” and constructor which Constructs full name and assigned to class property.

TypeScript class code example:

class Employee {
    fullname: string;
    constructor(public firstName: string, public
middleInitial: string, public lastName: string) {
        this.fullname = firstName + "
" + middleInitial + " " + lastName;
    }
}
 
var user = new Employee("Shourya", "Nagnath", "Kendre");
 
window.onload = () => {
    var elFullNameName =
document.getElementById('lblFullNameName');
    elFullNameName.innerHTML = user.fullname;
};

HTML code:

<html lang="en">
<head>
    <meta charset="utf-8" />
    <title>TypeScript HTML App</title>
    <link rel="stylesheet" href="app.css" type="text/css" />
      <script src="ClassesExample.js"></script>
</head>
<body>
    <h3>Classes example</h3>
<label id="lblFullNameName"></label>
</body>
</html>

SQL Server 2016 User Logins Management

2. October 2017 Vaibhav S Articles, Database, SQL, SQL Server (0)

This is my 2nd article on SQL server 2016, in this article I will explain in detail how to maintain user permissions or security.

SQL Server Security Management

A. Developers Access Control

It is very crucial to manage each user’s access rights as it can become hectic when need to manage 10-20 users with multiple permissions on their windows authentication.

To manage permissions among users, SQL has provided access management using windows groups.

Below are the steps to create any local windows group

1.  Search “Computer Management” and open it.
2.  Expand “Local Users and Groups” and then open Groups.

3.  Add new local windows user group and map windows users under it. Eg. “SQLUserGP_Read”, “SQLUserGP_Write” and “SQLUserGP_DBA”

Windows group can be added in same fashion like windows user.
It is always advisable to provide execute rights to all developers so execute below query for same.
GRANT EXECUTE TO [VSPC0129\SQLUserGP_Read]
GRANT EXECUTE TO [VSPC0129\SQLUserGP_Write]


B.  SQL/Web User Access Control

To restrict hackers from manipulate our database, we should always provide minimal access to users.
It can be done at object level and database level.

Object Level

Advisable to provide access to only required objects so that other objects can’t be accessed in case of any hacking attempts.

Database Level 

Keep all the interactions through stored procedure and user should only be allowed to execute SPs (will not have even select rights).

SQL server 2016 Transfer Maintenance Plan from One Server to Another

2. October 2017 Vaibhav S Articles, Database, SQL, SQL Server (0)

 Hi this is Vaibhav Shringi, This is my 3rd article on SQL server 2016, in this article, will explain in detail how to transfer maintenance plan from one server to another.

In the following example, I will use two servers NMK135 and VS12345 for explanation and sample users Vadmin and nmk12345.

Transfer Maintenance Plan from One Server to Another

1. Connect to Source Integration server

Connect to Integration Services in SQL Server Management Studio (Where Maintenance plan already present Say SERVER-1)


2. Export Maintenance plan package from SERVER-1.

Connect with appropriate permissions and export the “DBMaintenancePlan” package.


3. Select Package Location as File System and browse for Package path to save “DBMaintenancePlan.dtsx” file.

4. Save and OK to complete the export process in SERVER-1.

5. Transfer the newly exported file to new server file system (say SERVER-2).

6. Transfer any required Rebuild Indexes and UpdateStatistics SPs from SERVER-1 to SERVER-2(if any).

7. Connect to Integration Services of SERVER-2. (use step 1). Import the previously exported package.


8. Connect to Database Engine of SERVER-2


9. Verify imported Maintenance Plan on SERVER-2.


10. Modify Plan to change some config entries.


11. Follow below steps ONLY IF WANT TO change Job Schedule Timing.

Click on Calendar button present right side of “Schedule” tab. Change appropriately and save the changes.


Below Step 12 to 14 are for “Nightly_DB_maintenance” Subplan.

Click on Nightly_DB_maintenance Subplan to see below screen.


12. Verify Rebuild and update statistics tasks.

13. Verify Database Backup Location and database names.

      => Double click on “Full Backup Database task”.
      => Verify Folder location.


14. Verify Backup File Cleanup Period.

     => Double click on “CleanUp BackUp Files”.
     => Verify File Age. (Prefer to have 2 weeks) 


Below Step 15 is for “Every2Hrs_DB_Tran_Bkp” Subplan.

Click on Nightly_DB_maintenance Subplan to see below screen


15. Verify Transactional backup location and databases names.

      =>Double click on “Back Up Database Task”
      =>Verify Folder location. 



16. Save the Maintenance plan and close it. 

How to VERIFY Maintenance Plan Jobs?

VERIFY Maintenance Plan Jobs:

1. Open property window of both the jobs (right click on Job name)

  a. DBMaintenancePlan.Every2Hrs_DB_Tran_Bkp
  b. DBMaintenancePlan.Nightly_DB_Maintenance


2. Job owner:

    => If face any access related issue with Vadmin then change Job owner to “SA”.
    => We are facing this issue in VS12345 because of SQL agent service default configuration. 

3. Review Schedule Time etc.
