This document discusses cursors in PL/SQL. It defines a cursor as a pointer that is used to point to individual rows in a database table. It explains that there are two types of cursors: implicit cursors and explicit cursors. Implicit cursors are used automatically for SQL statements and have attributes like %FOUND and %ROWCOUNT to check the status of DML operations. Explicit cursors must be declared, opened, values fetched from them into variables, and then closed to access multiple rows from a table in a controlled manner using PL/SQL.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.

Paketo Buildpacks : la meilleure façon de construire des images OCI? DevopsDa...Anthony Dahanne
Les Buildpacks existent depuis plus de 10 ans ! D’abord, ils étaient utilisés pour détecter et construire une application avant de la déployer sur certains PaaS. Ensuite, nous avons pu créer des images Docker (OCI) avec leur dernière génération, les Cloud Native Buildpacks (CNCF en incubation). Sont-ils une bonne alternative au Dockerfile ? Que sont les buildpacks Paketo ? Quelles communautés les soutiennent et comment ?

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
Exploring Innovations in Data Repository Solutions - Insights from the U.S. G...Globus
The U.S. Geological Survey (USGS) has made substantial investments in meeting evolving scientific, technical, and policy driven demands on storing, managing, and delivering data. As these demands continue to grow in complexity and scale, the USGS must continue to explore innovative solutions to improve its management, curation, sharing, delivering, and preservation approaches for large-scale research data. Supporting these needs, the USGS has partnered with the University of Chicago-Globus to research and develop advanced repository components and workflows leveraging its current investment in Globus. The primary outcome of this partnership includes the development of a prototype enterprise repository, driven by USGS Data Release requirements, through exploration and implementation of the entire suite of the Globus platform offerings, including Globus Flow, Globus Auth, Globus Transfer, and Globus Search. This presentation will provide insights into this research partnership, introduce the unique requirements and challenges being addressed and provide relevant project progress.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

PLSQL CURSOR

Mar. 30
PLSQL CURSOR
Cursor is a pointer, used to point individual rows in the table. It is associated each
rows from the database table. If we want to perform any operation on individual
rows from the table, we use cursor. Cursor contains more than one rows or single
which returns from sql statements. They are created by default when any DML
(inser, update and delete) operation performed on database. It is used to check
DML operation in database successful performed or not.
E.g.
Single row contains
Cursor c1 is select * from stude where roll=1;
Above cursor name ‘c1’ which contains one record of roll no. 1.
Multi Rows Contains
Cursor c1 is select * from student;
Above we have not specify condition so Cursor ‘c1’ contains all rows from table
student.
Cursor are two types
1. Implicit cursor
2. Explicit Cursor
Discuss about Implicit Cursor
No need to declare cursor keywords. Sql statements are executed in
personal sql work area. Cursor are used to point that work area
implicitly(Automatically). Then question is how we know that whether it points to
rows or not. For that to check from table we use some attributes of cursor.

Attributes of Implicit Cursor
1. %Found :-It is Boolean attributes which returns either true or false. If recent
sql statement affects single row or multiple rows then it returns true.
2. %NotFound:- It is opposite to %Found attribute. If recent sql statement
doesn’t affect any rows it returns true.
3. %IsOpen :- Though it is Implicit cursor so after executed it automatically
closed immediate. If you use %IsOpen attribute it always returns false.
Because before IsOpen attributes cursor is already closed.
4. %RowCount:- It count number of rows affected in most recent sql
statements.
Discuss about Explicit Cursor
To keep control over the cursor we explicitly declared it with Cursor keyword. And
cursor should define in declaration statement. It is created with select statement,
that returns more than one rows or single rows.
Explicit Cursor declaration
Cursor c1 is select * from stude where roll=1; returns only one rows from table
Cursor c1 is select * from student; returns more thn one rows from table.
Following steps are used for Explicit cursor
1. Declare the cursor
2. Open the cursor
3. Fetching the cursor
4. Close the cursor

Declare the cursor
The cursor declaration is specify in declare part of PLSQL. It is associated with
name and select statement.
E.g.
Declare
Cursor c1 is select roll,name,mark from student where roll=1;
Begin
End;
Above c1 is the name of cursor and that is stored single rows from table where
roll=1;
Open the cursor
Open cursor is used to active the cursor and after active it will allocate memory
for cursor. If it will not activate then it can’t fetch its value to specified variable.
E.g.
Open c1;
Fetching the Cursor
Fetching the cursor value to variable. It will fetch value from cursor at time one
row only. If you will not fetch then how you extract value from cursor.
E.g.
Fetch c1 into roll,name,mark;
After write above line you can find the value of cursor c1 populate(send) to roll,
name & mark variable.
Then You can extend your program like as
If mark > 30 then
Dbms_output.put_line(‘Student is passes’);

Else
Dbms_output.put_line(‘Student is failed’);
End if;
Close Cursor
It is used to close the PLSQL cursor. After closed it free or de-allocate the
memory.
************STEPS ARE CLOSED*********
Difference Between Implicit Cursor & Explicit Cursor
SLNO Implicit Cursor Explicit Cursor
1 It automatically associated with
database Cursor
To take control over cursor we
declare it
2 No Need Cursor Keyword for declare It require declaration Like
“Cursor C1”
3 It can associated with Single/Multiple
Rows
It can associated with
Single/Multiple Rows
4 Though cursor has no name then to
check we use SQL keyword.
“SQL%Attribute” SQL%Found,
SQL%isOpen SQL%NotFound
SQL%RowCount
It has explicit cursor name c1. So
to check we use “C1%attribute”
C1%Found C1%NotFound
C1%IsOpen like this….
5 No required Requited Fetching
6 No Requied Required To Close
Prepared By JAVATECH Search us In the World
E.g. of Implicit Cursor. Remember it has no name and declaration. And to use
attributes of Implicit Cursor use the SQL keyword.
