How to handle the database objects security in database through stored procedures

February 13th, 2013 No comments

Case: An user X owns a stored procedure that access a table owned by another user Y, and that table has a trigger that updates another table owned by user Z

Clumsy Solution –> Grant explicit permissions to user X on table1 and table2, similarly grant execute permissions and table access to users Y and Z. In a production environment think of many users available in a database and thousands of objects, it is not possible.

Good Solution –> Create all objects with dbo user and provide execute permission ONLY on stored procedures to user X, thus when user would execute the stored procedure, SP would be able to modify the table1 and trigger on table1 would be able to modify tabl2, though explicit access on tables have not been granted to user X. This is how stored procedure maintain the security features. User X shall not be able to access table1 and table2 explicity but stored procedure run by user X can modify those tables.

This is how objects gets created in production environment.

How to remove an user from public group

February 13th, 2013 No comments

There is no way to remove an user from “public” group. However, you can revoke the commands permissions on given objects from “public” and thus users belongs only to given group would be able to execute those commands on those objects.

Database user group – Way to remove an user from a group

February 13th, 2013 No comments

1. Group is a database  specific.

2. An user can’t be a part of 2 different groups

3. An user can be a part of 2 groups only in case of other group is “public”.

4. An user shall always be part of “public” group .

5. To remove an user from a group (not from public) change the group of user to “public”.

sp_changegroup “public”, X

SAP SYbase ASE, SAP Sybase IQ and SAP HANA – In a snapshot

February 3rd, 2013 No comments
SAP Sybase ASE SAP Sybase IQ SAP HANA
High performance, reliable, scalable and resource-efficient OLTP database. Heavily optimize ASE for virtualized and cloud infrastructure    Aims to provide maximum performance and efficiency when running both OLTP and OLAP workloads on the SAME DATA and at the SAME TIME
Capability to handle transactional workloads. It is good to chose in case of budgetary constraints.   In- memory database, very high capability to handle transactional workloads.
SAP Sybase ASE is planned to be the preferred transactional database in the SAP Real-Time Data Platform for running SAP applications, SAP partner applications and custom applications    SAP HANA is planned to be the preferred database in the SAP Real-Time Data Platform for applications that need to run analytic and transactional workload on the same data at the same time 
  Sybase IQ is planned to focus on evolving columnar compression capabilities for effectively storing and processing data  SAP HANA is planned to leverage IP from Sybase IQ, such as in-database algorithms, Hadoop integration, index optimizations, and ELT capabilities for performing transforms in the Hana database 
  Plan to leverage Sybase IQ as near-line storage for SAP BW as well as leverage the technology in SAP ILM portfolio for archiving from the Business Suite Plan to leverage SAP HANA as database for native applications, SAP BW, as well as the Business Suite
  High-performance analytics server planned to deliver cost effectively for large volume data scenarios 

 Open platform for large scale data warehouse

 Analytical data mart for aged data in a BW+HANA+IQ scenario

 Cost effective data management scaling to extreme data volumes

 

 

 

 

 

Real-time platform for analytics and applications that simplified data management approaches to deliver real-time results 

 Operational / agile data mart for real-time scenarios

 Analytical data mart for complex real-time calculations

 Database for BW powered by SAP HANA

SAP Hana With Free Sybase Database

January 17th, 2013 No comments

“Customers could choose to deploy ASE or Hana in whatever mix of configurations they want,” explained Prakash Darji, SAP’s global VP for data warehouse solutions & SAP Hana platform. SAP customers could use Hana to accelerate certain Business Suite processes while leaving other processes on ASE”

ASE 15.7.0.030 (ASE 15.7 ESD#3) Released & Its New Features !

December 24th, 2012 3 comments

New features of ESD#2 and ESD#3 here:

  • Fixes: With ESD#3 you get all of the fixes for database issues that have been made available since the initial release of release 15.7.
  • In-row LOB compression: ASE can store LOB data in-row or off-row (on special LOB pages). Data compression was introduced with ASE 15.7, but in-row LOBs have not been compressed. With the new version you will get in-row LOB compression. For some SAP tables this can make a big difference. For an example, please have a look at this blog from Hüseyin Bilgen who shares his experiences.
  • Hash-based statistics: This feature helps speed up the updating of index statistics.
  • Plan sharing: In the past a database query that was executed more than once in parallel would result in multiple query plans which could be different (depending on the values provided at compilation time). When you are running ESD#3, plans for queries running in parallel are cloned, saving the cost of recompilation and ensuring that the queries use the same plan.
  • Enhanced monitoring: You will see more metrics on several screens of the DBA Cockpit. Since we are using early versions of the ESDs in our development systems, we have already been able to include some of these in the DBA Cockpit versions released during summer 2012 (such as SAP_BASIS 7.02 SP12). For example: enhanced SQL statement statistics, spinlock monitoring, separation of I/O time in read time and write time… There are also new monitoring features that are going to be used in future versions of the DBA Cockpit. One example is the new history of database and transaction dumps.
  • Talking about database and transaction dumps: There are several new features here that will make your life as a DBA easier. You can now run the dump transaction while a dump database is running. There is a new tool ‘sybrestore’ available with ESD#3 that will help you to restore the database when needed. We already updated our backup and recovery SAP Notes when ESD#2 was released to make use of the new features.
  • Reorg rebuild can be run online. I don’t think I need to say more.
  • The maximum size of a database is now 64TB. Just in case your compressed database was close to the 32TB limit before…
  • Asynchronous DB initialization: If you are expanding your database, the database is now available immediately and initialization is done in the background.
