Batch Execution on Unix like systems - File System permission

KNIME Analytics Platform

YES! I’ve got it.

The solution is not setting a -Djava.io.tmpdir system property in knime.ini not even setting TEMP environment variable before the KNIME workflow invocation.

It is setting the -Djava.io.tmpdir as system property when a workflow is being invoked in batch mode. This is the command that ended up successfully:

#!/bin/bash

workflow_name=test_workflow_01
run_identifier=knime_wf_${workflow_mame}_run_$(date +%Y-%m-%d-%H-%M-%S)


current_dir="$PWD"
nohup /opt/ders/knime  \
        -nosplash \
        -application org.knime.product.KNIME_BATCH_APPLICATION \
        -workflowFile="/home/ders/sify_int/${workflow_name}.knwf" \
        -workflow.variable=delay_in_sec,3,int \
        -workflow.variable=correlation_id,correlation_id_not_set,String \
        -workflow.variable=job_name,"unnamed_job",String \
        -credential="sify_new_vavdev;*****;*****" \
        -reset \
        -preferences=/home/ders/phaeton.epf \
        -consoleLog \
        -destDir=$current_dir/out/${run_identifier}-out/ \
        -vmargs -Djava.io.tmpdir=/opt/ders/temp -Dorg.knime.core.maxThreads=2 -Xmx4g > ${run_identifier}.log 2>&1 &
