+.SH DESCRIPTION    
+The \f3jmap\fR command prints shared object memory maps or heap memory details of a specified process, core file, or remote debug server\&. If the specified process is running on a 64-bit Java Virtual Machine (JVM), then you might need to specify the \f3-J-d64\fR option, for example: \f3jmap\fR\f3-J-d64 -heap pid\fR\&.
+.PP
+\fINote:\fR This utility is unsupported and might not be available in future releases of the JDK\&. On Windows Systems where the \f3dbgeng\&.dll\fR file is not present, Debugging Tools For Windows must be installed to make these tools work\&. The \f3PATH\fR environment variable should contain the location of the \f3jvm\&.dll\fR file that is used by the target process or the location from which the crash dump file was produced, for example: \f3set PATH=%JDK_HOME%\ejre\ebin\eclient;%PATH%\fR\&.
+.SH OPTIONS    
+.TP     
+<no option>
+When no option is used, the \f3jmap\fR command prints shared object mappings\&. For each shared object loaded in the target JVM, the start address, size of the mapping, and the full path of the shared object file are printed\&. This behavior is similar to the Oracle Solaris \f3pmap\fR utility\&.

-<no option> 
-When no option is used jmap prints shared object mappings. For each shared object loaded in the target VM, start address, the size of the mapping, and the full path of the shared object file are printed. This is similar to the Solaris \f3pmap\fP utility. 
+Dumps the Java heap in \f3hprof\fR binary format to \f3filename\fR\&. The \f3live\fR suboption is optional, but when specified, only the active objects in the heap are dumped\&. To browse the heap dump, you can use the jhat(1) command to read the generated file\&.
+.TP
+-finalizerinfo
 .br
-.TP 3
-\-dump:[live,]format=b,file=<filename> 
-Dumps the Java heap in hprof binary format to filename. The \f2live\fP suboption is optional. If specified, only the live objects in the heap are dumped. To browse the heap dump, you can use jhat(1) (Java Heap Analysis Tool) to read the generated file. 
-.br
-.TP 3
-\-finalizerinfo 
-Prints information on objects awaiting finalization. 
-.br
-.TP 3
-\-heap 
-Prints a heap summary. GC algorithm used, heap configuration and generation wise heap usage are printed. 
+Prints information about objects that are awaiting finalization\&.
+.TP
+-heap
 .br
-.TP 3
-\-histo[:live] 
-Prints a histogram of the heap. For each Java class, number of objects, memory size in bytes, and fully qualified class names are printed. VM internal class names are printed with '*' prefix. If the \f2live\fP suboption is specified, only live objects are counted. 
+Prints a heap summary of the garbage collection used, the head configuration, and generation-wise heap usage\&. In addition, the number and size of interned Strings are printed\&.
+.TP
+-histo[:live]
 .br
-.TP 3
-\-permstat 
-Prints class loader wise statistics of permanent generation of Java heap. For each class loader, its name, liveness, address, parent class loader, and the number and size of classes it has loaded are printed. In addition, the number and size of interned Strings are printed. 
+Prints a histogram of the heap\&. For each Java class, the number of objects, memory size in bytes, and the fully qualified class names are printed\&. The JVM internal class names are printed with an asterisk (*) prefix\&. If the \f3live\fR suboption is specified, then only active objects are counted\&.
+.TP
