Repository Database



Overview

Repository database is used to save Raw TDS data and the analysis results.

The data is loaded by the ASE Cockpit

SAP ASE is the only supported repository database in current release.

No special platform requirement for repository database.

SAP ASE 15.7 or above version is required for repository database.

Repository database in local network with the cockpit server will bring significant performance improvement.


Overview (Cont.)

The Repository Database should be installed on a dedicated ASE server

Repository load, analysis and replay are performance intensive

Configuration and resource requirements are specific to Workload Analyzer

A license for an additional ASE server will be included with the purchase of the Workload Analyzer feature in Corona GA.

Workload Replay



Workload Replay OverviewReplay a workload and view analysis result

Prepare replay environment (outside of Cockpit)

Restore databases and configuration manually

Create corresponding logins and roles

Default configuration should be the same as source ASE server.

Connect repository database

Start a new replay

Run replay workload wizard

Replay workload wizard guides you through the workload replay process

Analyze replayed workload

Import the replay generated PCAP files using import wizard

Analyze the imported workload

View analysis result


Administration

To capture the workload during replay. Following permissions are needed.

Granular permissions disabled:

User with sa or sso role

Granular permissions enabled:

User with “set tracing any process” privilege


Installation and Configuration

•No special installation steps required

•Integrated inside ASE installation

Install a separate Cockpit server to manage replay ASE server from Cockpit server that is used to manage the source ASE server.

Prepare repository database that has captured workload.

There should be three ASE servers as part of the workload capture and replay process:

1) The original production ASE server on which the workload was captured

2) The dedicated ASE server for the Workload Analyzer repository database (sybcatdb)

3) The target server for the replay session


Upgrade

Not applicable

This feature introduced into ASE Corona.


Licensing

• Required for Corona GA release (Capture and Replay)

• There is no special license requirement for the repository database.

Import the replay generated PCAP files using import wizard

Analyze the imported workload


Similar operation as imported workload


Step 4: Replay a workload and view analysis result

Run replay wizard

Select a workload that is going to be replayed


Licensing

Licensing will be required for Corona GA

The ASE Cockpit will not be licensed but the ability to capture workload on an ASE server will be

controlled by a license.


Installation and Configuration

ASE Cockpit must be installed and running

ASE Cockpit Technical User must be configured

•See the Server menu in the ASE Cockpit Explore tab

The ASE Cockpit user must have a valid login to the ASE server

•This is required for authentication with ASE Cockpit

Before starting the workload capture, import and replay, you must prepare the repository database and make sure ASE Cockpit is connected to the repository database via the repository wizard.

It is ideal to use a separate Cockpit server to manage the replay ASE server from the Cockpit server that is used to manage the source ASE server.
