Subject [jira] [Commented] (SOLR-9168) Add availability to specify own oom handing script
Date Thu, 24 May 2018 23:45:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-9168?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16490001#comment-16490001
] 

Erick Erickson commented on SOLR-9168:
--------------------------------------

Properties props = System.getProperties();

Some interesting ones are
"java.specification.version" -> "1.8"
"java.runtime.version" -> "1.8.0_151-b12"
"java.version" -> "1.8.0_151"

although I purely hate trying to parse one of these. Is "151" greater or less than "92"?

> Right now the start script always uses $SOLR_TIP/bin/oom_solr.sh  to handle OutOfMemoryException.
This script only kills instance of solr.
> We need to do some additional things (e.g sent mail about this exception)
> What do you think about adding possibility to set up own script?
> Proposition:
> {code}
> if [ -z "$SOLR_OOM_SCRIPT" ]; then
>   SOLR_OOM_SCRIPT=$SOLR_TIP/bin/oom_solr.sh 
> fi
> [...]
> nohup "$JAVA" "${SOLR_START_OPTS[@]}" $SOLR_ADDL_ARGS \
> 	"-XX:OnOutOfMemoryError=$SOLR_OOM_SCRIPT $SOLR_PORT $SOLR_LOGS_DIR" \
>         -jar start.jar "${SOLR_JETTY_CONFIG[@]}" \
> 	1>"$SOLR_LOGS_DIR/solr-$SOLR_PORT-console.log" 2>&1 & echo $! > "$SOLR_PID_DIR/solr-$SOLR_PORT.pid"
> {code}
