| 2 | ============================= |
| 3 | |
| 4 | This directory contains the list of D scripts which could be used to trace |
| 5 | Java application with help of Solaris(tm) 10 Dynamic Tracing (DTrace) |
| 6 | probes. |
| 7 | |
| 8 | The directory is organized as: |
| 9 | |
| 10 | * helpers/ |
| 11 | |
| 12 | This directory contains the auxiliary script to launch Java application |
| 13 | with D script to debug. See more comments in the scripts. |
| 14 | |
| 15 | * hotspot/ |
| 16 | |
| 17 | This directory contains D scripts which demonstrate usage of 'hotspot' |
| 18 | provider probes. |
| 19 | |
| 20 | |
| 21 | * hotspot_jni/ |
| 22 | |
| 23 | This directory contains D scripts which demonstrate usage of 'hotspot_jni' |
| 24 | provider probes. |

| 28 | Requirements to run DTrace |
| 29 | ========================== |
| 30 | |
| 31 | 1. dtrace framework should be installed; (check if /usr/sbin/dtrace exists) |
| 32 | |
| 33 | 2. the user should have the following rights: |
| 34 | dtrace_proc, dtrace_user, dtrace_kernel |
| 35 | |
| 36 | To give a user a privilege on login, insert a line into the |
| 37 | /etc/user_attr file of the form: |
| 38 | user-name::::defaultpriv=basic,dtrace_proc,dtrace_user,dtrace_kernel |
| 39 | |
| 40 | or |
| 41 | |
| 42 | To give a running process an DTrace privilege, use the ppriv(1) command: |
| 43 | # ppriv -s A+privilege process-ID |
