Description

This error indicates that SAP S/4HANA attempted to access a critical SQL library or database object, but it was found to be in an invalid or unusable state. This typically prevents database operations or system functions from executing correctly, often occurring after system updates, database issues, or configuration changes.

ERR_SQL_INV_USABLE_LIBRARY

🔍

Known Causes

4 known causes

⚠️

Database Object Inconsistency

The metadata or internal state of the SQL library within the SAP HANA database might be inconsistent or corrupted, leading to its invalidation.

⚠️

Insufficient User Permissions

The SAP system user attempting to access the library might lack the necessary database or operating system permissions to load or execute it.

⚠️

Corrupted Library File

The underlying physical file or data associated with the SQL library could be corrupted on the file system, rendering it unusable by the database.

⚠️

Incompatible System Update

A recent SAP S/4HANA or database update, patch, or migration might have introduced an incompatibility, causing an existing library to become invalid.

Solutions

4 solutions available

1. Restart SAP Application Server Instances easy

A common cause is a temporary issue with the SQL library that a simple restart can resolve.

1

Access the SAP Management Console (SMICM) or use SAP transaction SM51 to identify and restart all relevant application server instances. Ensure you restart all instances to guarantee consistency.

N/A (GUI-based operation)

2

Alternatively, use the operating system command line to stop and start the SAP instances. Replace `<SID>` with your SAP system ID and `<instance_number>` with the instance number.

sudo su - <sidadm>
stop <SID>
start <SID>

2. Reactivate SAP ABAP Programs medium

Corrupted or inconsistent ABAP programs can lead to SQL library issues. Reactivating them can fix this.

1

Log in to your SAP S/4HANA system with an administrator user.

N/A

2

Execute transaction SE38 (ABAP Editor).

N/A

3

Enter the name of the program that is causing the error (if known) or a wildcard like `*` to search for programs. Click 'Display'.

Program name: * (or specific program)

4

From the program editor, choose 'Utilities' -> 'Maint. specs' -> 'Reactivate' or press Ctrl+F3.

N/A

5

If you have a list of programs, you can use transaction SE80 (Object Navigator) and navigate to the program, then right-click and select 'Activate'. Consider reactivating all programs in the affected package if the specific program is unknown.

N/A

3. Verify and Recreate SAP HANA Database Client Configuration advanced

Incorrect or outdated SAP HANA client configuration on the application servers can cause this error.

1

On each SAP application server, locate the `hdbcli` directory. This is typically found in the SAP system's executable path, e.g., `/usr/sap/<SID>/SYS/exe/uc/linuxx86_64/hdbcli`.

ls -l /usr/sap/<SID>/SYS/exe/uc/linuxx86_64/hdbcli

2

Check the existence and integrity of the `libsapjcr.so` file within this directory. If it's missing or corrupted, you'll need to replace it with a valid version from the SAP HANA client installation.

ls -l /usr/sap/<SID>/SYS/exe/uc/linuxx86_64/hdbcli/libsapjcr.so

3

If the library is problematic, download the appropriate SAP HANA Database Client from SAP Support Portal and extract it to a temporary location on the application server. Then, copy the `libsapjcr.so` file to the `hdbcli` directory, overwriting the existing one if necessary.

cp <path_to_downloaded_client>/hdbcli/libsapjcr.so /usr/sap/<SID>/SYS/exe/uc/linuxx86_64/hdbcli/

4

Ensure the file permissions are correct for the copied library.

chmod 755 /usr/sap/<SID>/SYS/exe/uc/linuxx86_64/hdbcli/libsapjcr.so

5

After updating the client library, restart the SAP application server instances as described in Solution 1.

N/A

4. Check SAP HANA Database and Application Server Compatibility advanced

Incompatibility between the SAP HANA database version and the SAPCAR/HANA client versions on the application servers can cause this error.

1

Determine the exact version of your SAP HANA database. You can check this via SAP HANA Studio or by executing the following SQL query in HANA Studio:

SELECT VERSION FROM M_DATABASE;

2

Identify the SAPCAR executable and the SAP HANA client versions installed on your SAP application servers. Check the file properties or version information of the relevant executables.

N/A (OS command to check file versions)

3

Consult the SAP Support Portal (SAP Note 1944755 - SAP HANA Client Versions) for a matrix of compatible SAP HANA database versions and SAP HANA client versions. Ensure your client versions are supported for your HANA database version.

N/A

4

If there's a version mismatch, download and install the correct SAP HANA client versions on all SAP application servers as per Solution 3. Remember to restart the application server instances afterwards.

N/A
