First of all, I am going to tell you something about IPC System on Unix Operating System and how it is related managing a Peoplesoft based environment. I took this topic first since PeopleSoft uses this for the application server and Process Scheduler server level; we need to know IPC System to understand how these PeopleSoft server processes work. We normally face issues related to this during our real-time supporting a Peoplesoft environment. A process, in Unix perspective, is a running program, created by the fork() system call. That's all. We can say, processes are created by 'forking'.  Forking means…

Did you know that users connected to DataMover will have database access similar to access id? What does this mean for you in a Production Environment? This can be really scary if you do not have security in place to ensure that DataMover access is restricted and controlled. Use the below SQL to determine who has access to DataMover, through which permission list and role. SELECT DISTINCT A.CLASSID, B.ROLENAME, C.ROLEUSER FROM PSAUTHITEM A, PSROLECLASS B, PSROLEUSER C, PSOPRDEFN D WHERE A.CLASSID = B.CLASSID AND B.ROLENAME = C.ROLENAME AND A.MENUNAME = 'DATA_MOVER' AND D.OPRID = C.ROLEUSER AND D.ACCTLOCK = 0 Ensure…

Long long ago, I started my software career as a web developer who wrote coding on Perl CGI and running them using Apache..... Good or bad, I forgot most of the coding part now, except If I see part of the code, I am able differentiate whether this is a shell script or a perl script. And one more skill(really?) that, I developed was to understand the script based on the extension provided to the script or program whether that is a shell script, perl script or python script (.sh,.ksh,.csh,.pl,.py sometimes .bash)... We were using a Linux distribution at that…

To define the term Data Warehouse (DW) especially to software developers who are new to the industry, have tried asking them a few simple questions before getting to the classic definition in the words of Bill Inmon. Some of the questions which leads to defining a Data Warehouse are: Q: What is Data? A: ‘Data’ is a collection of facts which are captured as it happens. E.g., the content present in a Survey Sheet is ‘Data’ Q: What is information? A: The details that are derived by processing the ‘Data’ are called Information. E.g., the details that are arrived from…

When I began writing this blog, I really thought that why did I even think of broaching the topic of change in the aviation sector. I am not an expert in this area so to say. But I am not a novice either. I mean around 4 years in this area has made me realize that this is an area incorporating change on a regular basis. Change is inevitable and has a deep influx in a domain that has been technology driven for ages. But the important factor is that when change is ‘properly guided’, it can yield excellent results…

This blog is opened to create a common platform for those who are working in the Travel & Distribution, Hospitality, Airlines, Transportation & Logistics Sectors. I like to encourage professionals working in these industries to share their thoughts on the latest developments, industry & technology trends and challenges, standard standards and best practices, solution needs and alternatives. This industry is characterised by early adoption of technology (and hence deployment of many legacy systems that are disparate in nature), many products that are still evolving, emergence of platform based solutions etc. The constant change in business models and operations in a…
