Sir, I have an ASA 5500 series device and i want to configure it user licence but i dont know how to configure it plz give me a proper solution

Easiest way to is so issue the following command on the cli:
more system:/run
This will get any preshared keys you have in the config.

Here is the manual:
http://www.cisco.com/en/US/docs/security/asa/asa70/quick/guide/70_ASAqk.html

Use the Cisco ASDM or SDM software, that will give you an easy graphical interface to configure the ASA. One of them would have been shipped with the device.

Don't forget the ASA has to pre-configured, just a simple config. Have HTTPS enabled and telnet/SSH helps as well if you dont have a serial port or the console cable.

Cisco's website will give you quite a lot of info for free...

Yes, it is possible and Yes you have to purchase it from Cisco.
Sorry, that is how they make the big bucks.
Consider a service contract on the unit, then you can download the firmware much cheaper.

If you are going for factory reset use the following commands

asa>enable
asa#write erase
asa#reload

Dont save the configuration when it prompts for it.

if you want to restore the configuration from the backup

1. You need to have a TFTP server
2. Locate the config file on your TFTP server
3. TFTP server should be reachable from ASA

then

asa#copy tftp flash

give the tftp server ip address
give the configuration file name (as exactly on the TFTP server)

reload

You can do this, For your ref i hv given you a link

PPPoE is not supported when failover is configured on the security appliance, or in multiple context or transparent mode. PPPoE is only supported in single, routed mode, without failover.

This is for the pixes, I haven't upgraded an asa yet...should be close or the same

* find latest version of code, these are usually *.bin files located on http://www.cisco.com/cgi-bin/tablebuild.pl/pix
* confirm the flash and RAM requirements of the PIX OS software versus what the PIX has (”sho ver”)
* make sure you have a backup of the old PIX OS and PDM to the tftp server (or at least confirm the software is there)
Note: You cannot back them up from the PIX, so you will need to download them and put them on the tftp server * put in a change control form
* once change controls confirms date/time do the upgrade:
wri mem*** only if you save your configs via tftp wri net conf t ca save all copy tftp://your tftp server ip/pix635.bin flash:imageskip this if you don't use pdm copy tftp://your tftp server ip/pdm-304.bin flash:pdm *** if this is a failover pair, upgrade the other pair reboot
