SAP S/4HANA Error 5155: Data Stream Read Failure
Description
Error 5155, 'ERR_TEXT_COMMON_STREAM_READ_ERROR', indicates a fundamental issue when SAP S/4HANA attempts to read data from a stream. This typically occurs during operations that involve processing data from files, network connections, or internal memory buffers, leading to an interruption in data flow.
Error Message
ERR_TEXT_COMMON_STREAM_READ_ERROR
Known Causes
4 known causesCorrupted Data Source
The file or data stream being accessed by SAP S/4HANA is corrupted, incomplete, or incorrectly formatted, preventing a successful read operation.
Network Connectivity Interruption
When reading data from a network stream (e.g., another server, external system), a temporary network disconnection or timeout has occurred.
Insufficient Access Permissions
The SAP system or the user executing the process lacks the necessary read permissions for the specified file or stream location.
Resource Limitations
The server or system processing the stream has run out of memory, disk space, or other critical resources required to complete the read operation.
Solutions
4 solutions available1. Verify Database Connection and Credentials easy
Ensures the SAP system can establish a stable and authenticated connection to the underlying HANA database.
1
Log in to your SAP S/4HANA system using SAP GUI.
2
Navigate to transaction SM59 (RFC Destinations (Client/Server)).
3
Locate and select the RFC destination that connects to your SAP HANA database. This is typically an 'HANA' or 'TCP/IP' type destination.
4
Click the 'Connection Test' button. If the connection fails, check the following:
5
Ensure the Hostname/IP Address and Instance Number (or System Number) in the RFC destination are correct.
6
Verify the credentials (Username and Password) used for the RFC connection are valid and have the necessary privileges in the HANA database. You might need to regenerate or reset these credentials.
7
Check network connectivity between the SAP application server and the HANA database server. Ensure firewalls are not blocking the necessary ports (default for HANA SQL is 3<instance_number>15).
8
If the connection test passes, proceed to test the 'Authorization Test' in SM59 to confirm user permissions.
2. Check HANA Database Resource Utilization medium
Addresses potential performance bottlenecks in the HANA database that could lead to read failures.
1
Log in to your SAP HANA database using SAP HANA Studio or SAP HANA Cockpit.
2
Monitor key performance indicators (KPIs) such as CPU utilization, memory usage, disk I/O, and network traffic on the HANA server.
3
Specifically, check for any processes or queries that are consuming excessive resources. This might indicate a runaway query or a resource contention issue.
SELECT * FROM M_CONNECTIONS WHERE CONNECTION_STATUS = 'RUNNING';4
Examine the 'M_ACTIVE_STATEMENTS' and 'M_STATEMENT_STATISTICS' views for long-running or resource-intensive SQL statements that might be causing the read failure.
SELECT * FROM M_ACTIVE_STATEMENTS ORDER BY ELAPSED_TIME DESC;5
If high resource utilization is observed, consider identifying and optimizing problematic queries, or scaling up the HANA hardware resources if necessary. Restarting the HANA database instance can sometimes temporarily alleviate resource exhaustion.
3. Investigate HANA Database Logs for Specific Errors medium
Provides detailed error information from the HANA database to pinpoint the root cause of the data stream read failure.
1
Access the SAP HANA database alert log. This can typically be found in the HANA trace directory.
2
Search for entries around the time the error 5155 occurred. Look for keywords like 'stream', 'read', 'error', 'failure', or specific SQL error codes.
3
Examine the 'indexserver' trace files for more detailed information on the specific operation that failed. The trace files are usually located in the `trace/` subdirectory of your HANA installation.
4
If the error message in the HANA logs points to a specific table, partition, or data corruption, further investigation into that specific object might be required. This could involve running HANA consistency checks.
CALL SYS.CHECK_CONSISTENCY();5
If you find recurring errors related to network issues, disk problems, or specific SQL statements, consult SAP Notes or engage SAP Support with the detailed log information.
4. Review and Patch SAP S/4HANA and HANA Components advanced
Ensures that the SAP S/4HANA system and its underlying HANA database are running on supported and stable versions with the latest relevant patches.
1
Determine the exact SAP S/4HANA version and Support Package Stack (SPS) you are currently running.
2
Check the SAP Support Portal (SAP ONE Support Launchpad) for any known issues related to error 5155 and your specific S/4HANA version. Search for SAP Notes using the error code and keywords.
3
Identify any available Support Packages or Enhancement Packages for your S/4HANA system that address stability or database connectivity issues.
4
Determine the SAP HANA database version and revision you are running.
5
Consult the SAP HANA certification matrix and product availability matrix to ensure your HANA version is compatible and supported for your S/4HANA version.
6
If your SAP HANA database is not on the latest recommended revision or patch level, plan and execute a HANA database update. Always perform such updates during a scheduled maintenance window and after thorough testing in a non-production environment.
7
After applying any relevant patches or updates to either S/4HANA or HANA, perform comprehensive testing to confirm the error is resolved.
