Error: /node_modules/ibm_db/build/Release/odbc_bindings.node: ELF file's phentsize not the expected size about node-ibm_db HOT 4 CLOSED

@kevin-omi The error says the processor architecture of system where you installed ibm_db and where you copied are not same. If processor architecture is different, you need to install ibm_db locally. Try below commands:

cd /opt/nodejs/node12/node_modules/ibm_db
npm install

Also, we need complete output of below commands from Amazon Linux 2 system:

uname
uname -m
node -v
npm ls ibm_db
db2level
echo $IBM_DB_HOME
echo $PATH
echo $LD_LIBRARY_PATH $DYLD_LIBRARY_PATH
npm install ibm_db

If you see architecture is arm64, ibm_db will not work as ibm_db is not supported for arm64 architecture. Thanks.

The following command is pointless because the ibm_db need write permissions to the license file and other directories, and the Lambda function does not have write permissions to its file system except for the mounted EFS or /tmp folder.

cd /opt/nodejs/node12/node_modules/ibm_db
npm install

@kevin-omi I suspect the odbc_bindings.node file is getting corrupted when ibm_db get copied from S3 to EFS via AWS DataSync. Please check the transfer mode. If it is not a binary transfer, the binary files will get corrupted.
You may try to install ibm_db under /tmp folder where lambda function has the write permission. Thanks.

@kevin-omi Let us know if you tried file transfer in binary mode and any update about the issue? Thanks.
