Sybase ASE (Adaptive Server Enterprise)
This article outlines the integration with the Sybase ASE (Adaptive Server Enterprise) connector, enabling metadata management through features such as crawling, profiling, querying, data preview, and automatic and manual lineage building. The connector extracts metadata for schemas, tables, views, columns, procedures, functions, triggers, indexes, and relationships.
The connector establishes connectivity to Sybase ASE using the jTDS JDBC driver. It authenticates using a service account configured with the required database credentials and permissions to access system catalog tables for metadata extraction and user tables and views for profiling, data preview, and lineage source code retrieval.

Set up a Connection
Prerequisites
The prerequisites to establish a connection:
Whitelisting Ports
Make sure that inbound port “5000” is whitelisted to enable successful connectivity with the Sybase ASE.
The default port number for Sybase ASE is 5000. If a different port is used, ensure that the updated port number is specified during connection setup, the port is whitelisted, and communication between the system and Sybase ASE is properly established.
Service Account User Permissions
It is recommended to use a separate service account to establish the connection to the data source, configured with the following minimum set of permissions.
👨💻 Who can provide these permissions? The Sybase ASE (Adaptive Server Enterprise) administrator grants these permissions, since users may not have sufficient access to assign them.

User Tables / Views (Data)
Target user tables and views
Select
The connector requires SELECT permission on the listed SAP ASE system tables to retrieve metadata required for schema discovery, object crawling, relationship extraction, index extraction, and source code retrieval.
SELECT permission on the target user tables and views is required to perform profiling operations, including row count, data preview, sample data retrieval, and column statistics.
Lineage building for views, stored procedures, and functions requires access to the object definitions stored in the syscomments system table.
Connection Configuration Steps
Users must have the Connector Creator role to configure a new connection.
Log into OvalEdge, go to Administration > Connectors, click + (New Connector), search for Sybase ASE (Adaptive Server Enterprise), and enter the required parameters.
Fields marked with an asterisk (*) are mandatory for establishing a connection.

Connectivity Troubleshooting
If incorrect parameters are entered, error messages may appear. Ensure all inputs are accurate to resolve these issues. If issues persist, contact the assigned support team.
1
JZ00L: Login failed / Login failed for user
Description: This error occurs when the supplied username or password is incorrect, the account is locked or expired, or the authentication configuration is invalid.
Resolution:
Verify the username and password by connecting through a SQL client such as isql or DBeaver.
Ensure the login account exists, is unlocked, and the password has not expired.
Confirm that the login has access to the target database.
2
JZ006: Caught IOException: java.net.ConnectException: Connection refused
Description: This error indicates that the application cannot establish a connection to the Sybase server because the host or port is incorrect, the database service is unavailable, or network traffic is blocked.
Resolution:
Verify that the server name and port number are correct.
Check network connectivity using tools such as telnet or nc.
Ensure the Sybase server is running and firewall rules allow the connection.
3
JZ006: Caught IOException: java.net.SocketTimeoutException: Read timed out
Description: This error occurs when the database server does not respond within the configured timeout period due to network latency, heavy server load, or unstable connectivity.
Resolution:
Increase the connection or socket timeout value.
Verify network latency and stability between the application and database server.
Review database server performance and firewall idle timeout settings.
4
UnknownHostException
Description: This error indicates that the configured hostname cannot be resolved to an IP address from the application server.Resolution:• Verify the hostname is entered correctly.• Validate DNS resolution using tools such as nslookup or dig.• Use the server IP address temporarily or update the DNS configuration if required.
5
No suitable driver / ClassNotFoundException: net.sourceforge.jtds.jdbc.Driver
Description: This error occurs when the required Sybase JDBC driver is unavailable, or the configured driver class is incorrect.
Resolution:
Ensure the Sybase-compatible JDBC driver is available in the application classpath.
Verify that the configured driver class and JDBC URL are correct.
Restart the application after updating the driver configuration.
6
JZ0C0: Connection is already closed / Stale pooled connection errors
Description: This error occurs when the connection pool attempts to reuse database connections that have already been closed due to database or network interruptions.
Resolution:
Enable connection validation before reusing pooled connections.
Configure appropriate connection idle timeout and maximum lifetime settings.
Enable connection keepalive to prevent stale connections.
7
Database '' not found / Cannot open database requested by login
Description: This error occurs when the specified database does not exist or the login account does not have permission to access it.
Resolution:
Verify that the database name is correct.
Ensure the login is mapped to the specified database.
Grant the required database access permissions if necessary.
8
Permission denied while metadata crawl (tables/views/procedures)
Description: This error occurs when the service account can connect to the database but lacks sufficient permissions to access system catalog tables or database objects required for metadata extraction.
Resolution:
Grant the required SELECT permissions on the necessary system catalog tables.
Verify metadata access using the same service account.
Use a service account with appropriate metadata access privileges.
9
SSL/TLS handshake failures (handshake_failure, certificate path errors)
Description: This error occurs due to SSL/TLS configuration issues such as untrusted certificates, protocol mismatches, or certificate validation failures.
Resolution:
Import the required certificate chain into the application's truststore.
Verify that the client and server use compatible TLS versions and cipher suites.
Ensure the certificate hostname matches the configured server name.
10
Intermittent failures only from the application node
Description: This error indicates that connectivity issues exist only from the application environment due to network policies, firewall rules, proxies, or security group restrictions.
Resolution:
Compare firewall, proxy, and security group settings between working and failing environments.
Test database connectivity directly from the application server.
Work with the network team to review routing rules and connection logs.
