RDBMS

Sybase ASE Connector

Sybase ASE (Adaptive Server Enterprise) is a relational database management system (RDBMS) designed for managing and storing structured data in enterprise-level applications.

OvalEdge enables connectivity to Sybase ASE using the jTDS driver, allowing for tasks such as crawling database objects, profiling sample data, executing queries, building relationships, and lineage.

Configuring Environment Variables

Configuring environment names enable you to select the appropriate environment from the drop-down list when adding a connector. This allows for consistent crawling of schemas across different environments, such as production (PROD), staging (STG), or temporary environments. It also facilitates schema comparisons and assists in application upgrades by providing a temporary environment that can be later deleted if needed.

Before establishing a connection, it is important to configure the environment names for the specific connector. If your environments have been configured, skip this step. 

Steps to Configure the Environment

  1. Log into the OvalEdge application.
  2. Navigate to AdministrationSystem Settings.
  3. Select the Connector tab.
  4. Find the key name “connector.environment”.
  5. Enter the desired environment values (PROD, STG) in the Value column.
  6. Click ✔ to Save.

    Note: The asterisk (*) denotes mandatory fields required for establishing a connection.

    Field Name

    Description

    Connector Type

    It allows you to select the connector from the drop-down list. By default, 'Sybase ASE' is displayed as the selected connector type.

                Connector Settings

    License Add Ons

    All the connectors will have a Base Connector License by default that allows you to crawl and profile to obtain the metadata and statistical information from a data source. 

    OvalEdge supports various License Add-Ons based on the connector’s functionality requirements.

    • Auto Lineage: Select the Auto Lineage Add-On license that enables the automatic construction of the Lineage of data objects for a connector with the Lineage feature.

    Connector Name*

    Provide a connector name for the Sybase ASE database in OvalEdge. This name will serve as a reference to identify the specific Sybase ASE database connection. Example: "SybaseASE_Connection_test"

    Connector Environment

    The Connector Environment drop-down list allows you to select the environment configured for the connector from the drop-down list. 

    For example, PROD, or STG (based on the configured items in the OvalEdge configuration for the connector.environment).

    The purpose of the environment field is to help you identify which connector is connecting what type of system environment (Production, STG, or QA).

    Note: The steps to set up environment variables are explained in the Configuring Environment Variables section.

    Server*

    Specify the name of the Sybase database instance server IP/URL, which is accessible by the OvalEdge application.

    Example

    IP : 190.x1.x3.xx90

    Server : ovalsybaserdbms.com

    Port*

    By default, port number 5000, related to the Sybase database, is displayed. If needed a new port number can be provided.

    Database*

    Enter the source database name for crawling.

    Driver*

    A JDBC driver is a Java library file with the extension .jar that connects to a database. The driver details associated with the Sybase database will be auto-populated by default.

    Username*

    Enter the Service Account Username of the Sybase ASE Server.

    Password*

    Enter the password of the Sybase server name.

    Connection String

    Set the Connection string toggle button to automatic, to get the details automatically from the credentials provided. Alternatively, you can manually enter the string.

    Admin Roles

    Integration Admins*

    To add Integration Admin Roles, search for or select one or more roles from the Integration Admin options, and then click on the Apply button.
    The responsibility of the Integration Admin includes configuring crawling and profiling settings for the connector, as well as deleting connectors, schemas, or data objects.

    Security and Governance Admins*

    To add Security and Governance Admin roles, search for or select one or more roles from the list, and then click on the Apply button.
    The security and Governance Admin is responsible for:

    • Configure role permissions for the connector and its associated data objects.
    • Add admins to set permissions for roles on the connector and its associated data objects.
    • Update governance roles.
    • Create custom fields.
    • Develop Service Request templates for the connector.
    • Create Approval workflows for the templates.

    No. of Archive Objects*

    The number of archive objects indicates the number of recent metadata modifications made to a dataset at a remote/source location. By default, the archive objects feature is deactivated. However, users may enable it by clicking the Archive toggle button and specifying the number of objects they wish to archive. 

    Select Bridge

    With the OvalEdge Bridge component, any cloud-hosted server can connect with any on-premise or public cloud data sources without modifying firewall rules. A bridge provides real-time control that makes it easy to manage data movement between any source and destination. For more information, refer to Bridge Overview.

    Connection Settings

    Description

    Crawler

    Crawler settings are configured to connect to a data source and collect and catalog all the data elements in the form of metadata. 

    Profiler




    The process of gathering statistics and informative summaries about the connected data source(s). Statistics can help assess the quality of data sources before using them for analysis. Profiling is always optional; crawling can be run without profiling. 

    Data Access 

    The Data Access Authorization is included in the crawler-specific connector settings to ensure that the right user is accessing the query sheet and queries in the data catalog. Here the system validates the user credentials and allows that particular user to access the query sheet and queries in the data catalog. 

    Query Policies

    It restricts the use of the selected query types based on your role.

    Access Instruction

    Access Instruction allows the data owner to instruct others on using the objects in the application.

    Business Glossary Settings

    The Business Glossary Setting provides flexibility and control over how they view and manage term association within the context of a business glossary at the connector level.

    Others

    The Enable/Disable Metadata Change Notifications option is used to set the change notification about the metadata changes of the data objects.

    • You can use the toggle button to set the Default Governance Roles (Steward, Owner Custodian, etc.) 
    • Using the Roles and Teams, you can select the role and team to receive the notification of metadata changes.

Note: For more information, refer to the Connector Settings.

Crawling of Schema(s)

A Crawl/Profile option allows you to select the specific schemas for the following operations: Crawl, Crawl & Profile, Profile, or Profile Unprofiled. For any scheduled crawlers and profilers, the defined run date and time are displayed to set.

  1. Navigate to the Connectors page, and click on the Crawl/Profile button.
    Select Schema For Crawling and Profiling pop-up window is displayed.
  2. The below list of actions is displayed.
    1. Crawl: It allows the crawling of the metadata of the selected schemas.
    2. Crawl & Profile: It allows crawling the metadata of the selected schemas and profiles the sample data.
    3. Profile: It allows the collection of table column statistics.
    4. Profile Unprofiled: It allows the profiling of data that has not been profiled.

Schedule: Connectors can also be scheduled for crawling and/or profiling in advance to run at prescribed times and selected intervals.

Note: For more information on Scheduling, refer to Scheduling Connector.
