Question

我们正在实现Jups EAP 7.1，其带有将Hiera和代码分离的puppet模块。我们使用以下命令

设置了最大和最小堆大小

wildfly::java_xmx:        '2048m'
wildfly::java_xms:        '2048m'

我现在在{hiera代码中添加wildfly::java_opts: '-XX:+UseG1GC'，已成功将其添加到standalone.conf中，如下所示：

#
 if [ "x$JAVA_OPTS" = "x" ]; then
    JAVA_OPTS="-Xms2048m -Xmx2048m -XX:MaxPermSize=128m"
-   JAVA_OPTS="$JAVA_OPTS "
+   JAVA_OPTS="$JAVA_OPTS -XX:+UseG1GC"
 else
    echo "JAVA_OPTS already set in environment; overriding default settings with values: $JAVA_OPTS"

当我进一步添加

 wildfly::java_opts: '-Xloggc:/opt/jboss-eap/gc_logs/jvm-gc.log  -XX:+PrintGCDetails   -XX:+PrintGCDateStamps'

第一个被删除:JAVA_OPTS="$JAVA_OPTS -XX:+UseG1GC"被删除。输出如下：

 if [ "x$JAVA_OPTS" = "x" ]; then
    JAVA_OPTS="-Xms2048m -Xmx2048m -XX:MaxPermSize=128m"
-   JAVA_OPTS="$JAVA_OPTS -XX:+UseG1GC"
+   JAVA_OPTS="$JAVA_OPTS -Xloggc:/opt/jboss-eap/gc_logs/jvm-gc.log  -XX:+PrintGCDetails   -XX:+PrintGCDateStamps"
 else
echo "JAVA_OPTS already set in environment; overriding default settings with values: $JAVA_OPTS".

无法向JAVA_OPTS添加新选项
