Workarounds and Mitigations

You may apply any published fix, or disable the ConfigAPI if not in use, by
running Solr with the system property "disable.configEdit=true".

The following steps should be done:
a) Fix the Solr server start script:

  o On UNIX:
     1. Edit /opt/IBM/InformationServer/shared-open-source/solr/start-solr.sh
     2. In the third line from the end of the file, change
        $EXEC "$ROOTDIR/solr/install/bin/solr" $SOLR_START_CMD -cloud -s
        "$ROOTDIR/solr/data/$i" -p $SCPI -z $HOSTNAME:$ZKPI
        to
        $EXEC "$ROOTDIR/solr/install/bin/solr" $SOLR_START_CMD -cloud -s
        "$ROOTDIR/solr/data/$i" -p $SCPI -z $HOSTNAME:$ZKPI
        -Ddisable.configEdit=true

  o On Windows:
     1. Edit C:\IBM\InformationServer\shared-open-source\solr\start-solr.bat
     2. In the third line from the end of the file, change
        "%SOLR_ROOT_DIRECTORY%install\bin\solr.cmd" start -cloud -s
        "%SOLR_ROOT_DIRECTORY:"=%data\!NODEID!" -p !SCPI! -z %HOSTNAME%:!ZKPI!
        !FOREGROUND!
        to
        "%SOLR_ROOT_DIRECTORY%install\bin\solr.cmd" start -cloud -s
        "%SOLR_ROOT_DIRECTORY:"=%data\!NODEID!" -p !SCPI! -z %HOSTNAME%:!ZKPI!
        !FOREGROUND! -Ddisable.configEdit=true

b) Follow the instructions in Step 2 of Technote to restart the
InfoSrvZookeeper, InfoSrvKafka and InfoSrvSolrCloud services.
