LTL or RTL Capture Crashes During Encrypted Password Login

Issue

For LTL or RTL capture from Sybase ASE, the Capture job terminates immediately when SAP RepAgent or Replication Server attempts to connect. The Capture log may contain errors similar to the following:

A crash report file is created in '<path>/dump/crashreport_<id>.txt'.
F_JT04A5: Coprocess '<capture-job>' has exited abruptly. This could be a network problem or a fatal error in the child coprocess.

Environment

• HVR 6
• Source database: Sybase ASE
• Capture method: LTL or RTL

Resolution

This issue occurs when the HVR process running Capture uses the Sybase runtime environment from a standalone SAP ASE installation instead of the SAP Replication Server installation.

To resolve this issue:

1. Stop the HVR Agent, Scheduler, or other process that provides the runtime environment for the Capture job.
2. Source SYBASE.sh or SYBASE.csh from the SAP Replication Server installation.
3. Verify that $SYBASE, $SYBASE_OCS, and $LD_LIBRARY_PATH refer to the Replication Server runtime environment. For the complete runtime environment requirements, see SAP Open Server SDK.
4. Restart the HVR process, then restart the Capture job and retry the RepAgent or Replication Server connection.

If disabling encrypted-password authentication allows the connection to succeed, this may indicate that the Capture process is using an incorrect or incomplete Sybase runtime environment. Configure the Replication Server runtime environment correctly before re-enabling encrypted-password authentication.

Cause

The HVR process running LTL or RTL Capture is using a Sybase runtime environment initialized from a standalone SAP ASE installation instead of the SAP Replication Server installation.

LTL and RTL capture depend on SAP Open Server components and their runtime dependencies provided by the Replication Server environment. When the Capture process uses an ASE-based environment, the required Open Server libraries or dependencies may not be loaded correctly during encrypted-password negotiation.
