I am trying to call an Oracle stored procedure from Spring Data R2DBC. I have currently set up querying either by annotation or R2DBC entity template and those work fine. However, I have not been able to call a proc with input/output parameters.
I saw some documentation mentioning support for procedure calls in R2DBC but have not found any concrete examples on how it is done. Any help or link to documentation or examples would be greatly appreciated.
The documentation for how to do procedural-calls can be found in the readme on github for the oracle-r2dbc driver:

In a project that I am working with Spring and JPA, I need to call a stored procedure but it does not have any table stored on the application side, only an input parameter is sent and returns an output parameter to know if I finish the process.
In all examples with JPA it always relates to JPA entities and the BD Tables.
Thank you for your contributions.
Take JPA out the pricture then. Assuming your application has a Datasource configured then inject that to the relevant code and get a connection:
https://docs.oracle.com/javase/7/docs/api/javax/sql/DataSource.html#getConnection()
Then just use standard JDBC.

I am relatively new to both, BIRT and gemfire but I know the basics. Thought I wasn't able to find how BIRT can fetch data from gemfire cache.
Can someone please help me on the procedure or whether it is possible or not?
It looks like BIRT uses JDBC (amongst other means) to talk to a backend datasource. Unfortunately GemFire does not provide a JDBC driver. You would need to develop a custom ODA Data Source as described here: https://wiki.eclipse.org/Use_Case_-_Create_a_Custom_ODA_Data_Source
I am using Spring SimpleJBDCTemplate for a DB2 stored procedure call, the stored procedure returns around 200k records and it's kind of timing out from my java code.
I tried setMaxRecords option, it helps to an extent.
Is there something like a batch read or a page read that are part of Spring?
Spring has a library that is called Spring Batch. You should definitley see documentation and try to adapt it to your problem.
Please refer to this: Spring-Batch
Is it possible to implement a stored procedure call in oracle, which has more than 3 output (OUT)
using Ibatis 2.3.4 integrated with Spring version 2.7,
If possible please provide link for reference,
Thanks in Advance
I implemented oracle store procedure called using iBatis on Spring, and can't find the limitation about 3 OUT parameter as you described above. In my opinion, it's possible to create store procedure for your purpose, use this link as reference:
Ibatis and Oracle Procedure
If you got any problem, please let me know.
HTH.
im quite new to EJB3 and was wondering if it is possible to edit a specific record from a table using EJB3?
If so, are there any tutorials and examples on how to do this?
Thanks in advance
Since entity beans were deprecated in the EJB3 standatd, you'd do this using either plain JDBC or JPA, but neither of these requires EJBs to be used.
