Hi, Yes Chris, Open J9 have an issue on their backlog for this: https://github.com/eclipse/openj9/issues/8195 This is related to the GC_LOG_OPTS in solr.cmd. Unfortunately, this can't be set in solr.in.cmd due to: "For Java 9 or higher: GC_LOG_OPTS is currently not supported. If you set it, the startup script will exit with failure." As the -verbose:gc option works, we've found that having the OpenJ9 java set the pre Java 9 GC_LOG_OPTS in solr.cmd appears to work, and doesn't change how HotSpot options are set. if !JAVA_MAJOR_VERSION! GEQ 9 IF "%JAVA_VENDOR%" IF NOT "IBM J9" ( REM instead of: if !JAVA_MAJOR_VERSION! GEQ 9 IF "%JAVA_VENDOR%"( IF NOT "%GC_LOG_OPTS%"=="" ( echo ERROR: On Java 9 you cannot set GC_LOG_OPTS, only default GC logging is available. Exiting GOTO :eof ) set GC_LOG_OPTS="-Xlog:gc*:file=\"!SOLR_LOGS_DIR!\solr_gc.log\":time,uptime:filecount=9,filesize=20M" ) else ( IF "%GC_LOG_OPTS%"=="" ( rem Set defaults for Java 8 set GC_LOG_OPTS=-verbose:gc ^ -XX:+PrintHeapAtGC ^ -XX:+PrintGCDetails ^ -XX:+PrintGCDateStamps ^ -XX:+PrintGCTimeStamps ^ -XX:+PrintTenuringDistribution ^ -XX:+PrintGCApplicationStoppedTime ) if "%JAVA_VENDOR%" == "IBM J9" ( set GC_LOG_OPTS=!GC_LOG_OPTS! "-Xverbosegclog:!SOLR_LOGS_DIR!\solr_gc.log" -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=9 -XX:GCLogFileSize=20M ) else ( set GC_LOG_OPTS=!GC_LOG_OPTS! "-Xloggc:!SOLR_LOGS_DIR!\solr_gc.log" -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=9 -XX:GCLogFileSize=20M ) )
Any chance that something like this can be put in a patch/future release?
