Introduction
This chapter introduces the various diagnostic and monitoring tools which can be used with J2SE 5.0.
The tools described here include command line utilities, command line options, and log files.
In almost all cases the command line utilities described in this chapter are either included in the Java
2 Platform Standard Edition Development Kit (JDK 5.0), or are operating system tools and utilities.
Although the JDK 5.0 command line utilities are included in the JDK download, it is important to note
that they can be used to diagnose issues and monitor applications that are deployed with the Java 2
Platform Standard Edition Runtime Environment 5.0 (JRE 5.0).
In general, the diagnostic tools and options described in this chapter use various mechanisms to
obtain the information they report. In many cases the mechanisms are specific to the virtual machine
implementation (5.0 in the case of this document), operating system, and version of each.
Consequently, there is some overlap of the information reported by some of the tools. This should be
viewed in the context of the various problems and issues for which these tools are intended. In many
cases only a subset of the tools will be applicable to an issue at a particular point in time.
Here are 10 tips I'd like to share to help extend your BB's Battery life:
- Options > Screen/Keyboard > Backlight Brightness -> (set to no higher than 50) --My setting: 10-- (effect = high)
- Options > Screen/Keyboard > Auto Dim Backlight -> this setting also brightens the backlight automatically beyond the above setting. Therefore, set above to as low as possible and enable this setting which will auto brighten when needed.
- Options > Screen/Keyboard > Backlight timeout -> Set to 30 seconds or lower --My setting 20sec-- (effect = medium)
- Options > Screen/Keyboard > LED coverage indicator -> set to off. (effect = low)
- Options > Screen/Keyboard > Key tone -> set to off (effect = low)
- Options > Screen/Keyboard > Audible roll -> set to off (effect = low)
- Profiles > Advanced > (Active) > If vibrate feature is used for phone, sms, IM's BBM's etc. Set Number of Vibrations to no more than 2 and for best battery life 1. (effect = high)
- Repeat step 6 for Number of Beeps (e.g set to 1 and set volume tohigh or set as 2 and set volume to medium...) (effect = medium)
- Profiles > Advanced > (Active) -> Set all Out of Holsterprofiles are set to Tone only. As much as possible avoid using vibrate or vibrate+tone for Out of holster. Here is were you'll need to enable repeat notification/LED flashing. (effect = high)
- Profiles > Advanced > (Active) > Repeat Notification -> For those who use a hip-mounted holster set LED flashing to None under the In holster profile. (effect = medium)
