How to Enable Agent XPs in MsSQL Server 2008 (Agent Xps Disabled)

Category: Administration,Errors and SolutionsFatih Acar @ 09:28

I upgraded MsSQL database version from MsSQL Server 2008 Express Edition to MsSQL Server 2008 Enterprise Edition. After upgrade operation, Agent XPs was disabled and MsSQL Server Agent servis could not start. I reconfigured Agent XPs configuration. The problem resolved.

Management Studio Object Explorer does not display the contents of the SQL Server Agent node unless these extended stored procedures are enabled regardless of the SQL Server Agent service state.

Agent XPs Possible Values

0, indicating that SQL Server Agent extended stored procedures are not available (the default).
1, indicating that SQL Server Agent extended stored procedures are available.

Show Current Value

EXEC SP_CONFIGURE ‘Agent XPs’

Reconfigure Agent XPs

EXEC SP_CONFIGURE ‘show advanced options’, 1;
GO
RECONFIGURE;
GO
SP_CONFIGURE ‘Agent XPs’, 1;
GO
RECONFIGURE
GO

After these parameter change operations you can restart agent service or sql server service to show Agent XPs enabled.

What is Lightweight Job in Oracle

Category: Administration,ProcedureFatih Acar @ 14:46

Use lightweight jobs when you have many short-duration jobs that run frequently. Under certain circumstances, using lightweight jobs can deliver a small performance gain.

Lightweight jobs have the following characteristics:

  • Unlike regular jobs, they are not schema objects.
  • They have a significant improvement in create and drop time over regular jobs because they do not have the overhead of creating a schema object.
  • They have lower average session creation time than regular jobs.
  • They have a small footprint on disk for job metadata and runtime data.

You designate a lightweight job by setting the job_style job attribute to LIGHTWEIGHT. The other job style is REGULAR, which is the default.

Like programs and schedules, regular jobs are schema objects. In releases before Oracle Database 11g Release 1, regular jobs were the only job style supported by the Scheduler.

A regular job offers the maximum flexibility but does entail some overhead when it is created or dropped. The user has fine-grained control of the privileges on the job, and the job can have as its action a program or a stored procedure owned by another user.

Category: SAP BasisFatih Acar @ 15:16

That scenario is required that we need to fetch data from the customer’s existing third party application. For example the customer is having some websites where the enquiries are being stored. Or The company employees who are on tour log their requests for leave in the portal. In such case we may have to provide an interface between their existing application to the upcoming SAP system.

SAP Security Audit Log Activation

Category: SAP Basis,System SecurityFatih Acar @ 14:52

As of Release 4.0, you can use the Security Audit Log to record security-related system information such as changes to user master records or unsuccessful logon attempts. This log is a tool designed for auditors who need to take a detailed look at what occurs in the SAP System. By activating the audit log, you keep a record of those activities that you specify for your audit. You can then access this information for evaluation in the form of an audit analysis report.
The Security Audit Log provides for long-term data access. The audit files are retained until you explicitly delete them. Currently, the Security Audit Log does not support the automatic archiving of the log files; however, you can manually archive them at any time.

SAP Security Audit Log

You can record the following information in the Security Audit Log

  • Successful and unsuccessful dialog logon attempts
  • Successful and unsuccessful RFC logon attempts
  • RFC calls to function modules
  • Changes to user master records
  • Successful and unsuccessful transaction starts
  • Changes to the audit configuration
