Tried the following: dnf install jansi but nothing changes

Any help will be appreciated

Thanks in advance!

We had a similar issue with our installation, due to security controls.
You may need to move the /tmp dir used by the janusgraph service to a location that is mounted without NOEXEC, and accessible by the openiam user (EX: /usr/local/openiam/tmp/).
Editing these two files solved the issue for us.

vi /usr/local/openiam/janusgraph/bin/gremlin.sh
## near line 122, append new option...
##JAVA_OPTIONS="${JAVA_OPTIONS} -Duser.working_dir=${USER_DIR} -Dtinkerpop.ext=${USER_EXT_DIR:-${SYSTEM_EXT_DIR}} -Dlog4j.configuration=conf/log4j-console.properties -Dgremlin.log4j.level=$GREMLIN_LOG_LEVEL -javaagent:$LIB/jamm-0.3.0.jar -Dgremlin.io.kryoShimService=org.janusgraph.hadoop.serialize.JanusGraphKryoShimService"
JAVA_OPTIONS="${JAVA_OPTIONS} -Duser.working_dir=${USER_DIR} -Dtinkerpop.ext=${USER_EXT_DIR:-${SYSTEM_EXT_DIR}} -Dlog4j.configuration=conf/log4j-console.properties -Dgremlin.log4j.level=$GREMLIN_LOG_LEVEL -javaagent:$LIB/jamm-0.3.0.jar -Dgremlin.io.kryoShimService=org.janusgraph.hadoop.serialize.JanusGraphKryoShimService -Djava.io.tmpdir=/usr/local/openiam/tmp"

vi /usr/local/openiam/janusgraph/bin/gremlin-server.sh

  #JAVA_OPTIONS="-Xms512m -Xmx512m -javaagent:$JANUSGRAPH_LIB/jamm-0.3.0.jar -Dgremlin.io.kryoShimService=org.janusgraph.hadoop.serialize.JanusGraphKryoShimService"

We have permissions set on the new tmp dir location as:

drwxr-xr-x.  2 openiam openiam          6 Sep  7 07:05 tmp

Then systemctl restart janusgraph

Hello!

That solved our issue

Thank you very much!
