If you’re looking for a user-friendly and cloud-based block storage system, Amazon EBS is the right solution for you. The system integrates with the entire AWS platform, and you’ll be able to use built-in Amazon security, backup and access control features. EBS provides you with four types of volumes for SSD-backed volumes and HDD-backed volumes..

It was only a few years ago when IT departments were able to manually handle vulnerabilities. Today, disruptive technologies and dynamic approaches to development have changed the digital landscape. Security is no longer the sole responsibility of the IT department. The borders of the security perimeter have been blurred, obscuring the visibility of digital spaces..

Migrating applications, data, and other workloads to the cloud is now commonplace among businesses of all sizes. A 2018 report on cloud computing trends revealed that 92 percent of companies now use public cloud services.
However, cloud migration remains a complex undertaking with several challenges, and getting it right is important. Read on to find out the challenges of cloud migration and ten tips for building a smart cloud migration plan..

Cloud computing is the new normal. Every time you are using a service or an application through an internet connection, you are using the cloud. Since most companies nowadays have part or all their databases hosted on the cloud, you ask how is the best way to do it. Migrating your database to the cloud can help you manage your workload by making your data available and easily scalable. Read on to learn about database cloud migration and tips to do it right..

An IT trends report has revealed that in one year alone more than 90 percent of organizations in the United States migrated critical infrastructure and applications to the cloud..

This article will discuss the connection between artificial intelligence and DevOps, with specific emphasis on the fields of machine learning and deep learning. You will then learn about five ways in which DevOps can leverage machine learning methods and AI to optimize workflows..

Through DB2 we can get the average time in ms disk access is having DB2. These times are crucial for the detection of a IO problem with DB2 instance.

Usually we take into consideration that a value close to 2-3ms is good, more than 10ms can indicate problems.

Avg ms/write:

select trunc(decimal(sum(pool_write_time))/decimal(

(sum(pool_data_writes)+sum(pool_index_writes))),3)

Avg ms/read:

When doing a snapshot from a storage array, if the server contains a DB2 instance running, there is no certainty that the snapshot contains a consistent copy of the database.

To launch a snapshot and ensure consistent copy in DB2 is possible to put the database at “write suspend”, that is, it overrides the disk access in write mode, and work in the buffer pool memory. Queries whether it will record but writes are performed only in memory.

Maybe there are other methods, in this short article, a simple way to know the port that serves DB2 server.

We get the name of the service TCP / IP:

> db2 get dbm cfg | grep SVCENAME

Capture the result:

TCP/IP Service name (SVCENAME) = db2TRP

Look at /etc/services:

> cat /etc/services | grep sapdb2QRP

db2TRP 5912/tcp # DB2 Communication Port

The listening port is 5912!
