SPARC IIIi: End of Life for SUN Fire V125, V215, V245 and V445

SUN Microsystems announced end of life (EOL) for V125, V215, V245 and V445. For SUN Fire servers powered by UltraSPARC IIIi last shipment is July 11, 2008. After this date only SUN Netra servers with UltraSPARC IIIi processors will be available.
If you are interested in the SPARC family follow this link to wikipedia.
SUN provides several upgrade paths:

Move to UltraSPARC T1 or T2 if single thread performance is not critical (e.g.:Sun Fire T1000 Server, Sun Fire T2000 Server)

Move to SPARC IV+/IV single thread performance is critical and you have to stay on SPARC architecture (e.g.: Sun Fire V490 Server, Sun Fire E2900 Server)

Move to AMD Opterion if single thread performance is critical and you only have to stay on Solaris (e.g.: Sun Fire X4200 Server, Sun Fire X4200 Server)

BPEL: timeout behaviour of synchronous processes

Everyone who ever used a synchronous BPEL process, has seen this exception in the opmn/logs of the BPEL engine, if the process needs more time than 45s:
Failed to handle dispatch message ... exception ORABPEL-05002
Message handle error.
An exception occurred while attempting to process the message "com.collaxa.cube.engine.dispatch.message.instance.PerformMessage"; the exception is: An exception occurred during transaction completion: ; nested exception is: javax.transaction.RollbackException: Timed out

If you search for this error on forums.oracle.com, you will get an easy answer:
change the syncMaxWaitTime via BPELConsole and you are done.

But this does not help... So what parameters have to be changed, to achieve that synchronous BPEL processes do not get this timeout?
The Oracle BPEL team knows about this problem, because they have written the answer in this document in the paragraph "Troubleshooting and Workarounds". But the problem is the misleading title "Setting Properties for BPEL Processes to Successfully Complete and Catch Exception Errors".

Here a short summary what you have to do:
1.) $Oracle_Home\j2ee\home\config\transaction-manager.xml:
change the transaction-timeout parameter t1

2.) $Oracle_Home\j2ee\home\application-deployments\orabpel\ ejb_ob_engine\orion-ejb-jar.xml:
change the transaction-timeout parameter t2, t2<t1

3.) BPELConsole:
Change the syncMaxWaitTime in all domains, where you need a bigger timeout

4.) OPMNCTL:
restart the application server


Now you can write synchronous BPEL processes without getting this timeout error after 45 seconds. But be careful! You will block threads by using long-running synchronous invokes. And if many of this processes are invoked, this can stall your BPEL engine ...

take a look at this link
The following specs were shown

CPU 1,6 GHz
512 MByte RAM (up to 2 GB)
533 MHz FSB
10" LCD
OS: XP or Vista

But nothing about about harddisk or the price. But it should be a competitor to ASUS EEE....
