LDOM Issue on T2000 ldmd cannot communicate with the hypervisor as the re

966984Oct 8 2012
Hi,

There were some issues with old primary LDOM at T2000 so I installed
new o/s 64 bit on SUN SPARC T2000 and reset SC on factor-default and
also installed LDOM 1.2 version. Seems like old hypervisor is not
deleted.
Now I am getting error.

#ldm list
Failed to connect to logical domain manager: Connection refused

So far I have trying the following steps. but still no luck

I installed version 1.2 LDOM. and also I updated SC. Plus I installed
below patches:

•118833-36, Kernel update patch
•124921-02, which contains updates to the Logical Domains 1.0 drivers
and utilities
•125043-01, which contains updates to the qcn (console) drivers.

SC> bootmode config="factory-default"
SC> poweroff
SC> resetsc -y
SC> poweron



Now I tried everything but still no luck

Here are some errot which I am getting

SELECT replace(location,'MTC','XXX')

SELECT 'MTC Foxconn India' FROM DUAL UNION ALL
SELECT 'MTC_Hosiden_1798467' FROM DUAL UNION ALL
SELECT 'EMS- MTC-QISDA CORPORATION' FROM DUAL UNION ALL
SELECT 'EMS MTC-BANSHING HKG' FROM DUAL

use replace function.

Are you sure MTC will not appear any where else in the text again.. and always it's going to be upper case only?
if so.. try the option of replace..

Hi Ravi,
MTC should be replaced like below in the following scenarios
ii)abcMTC MTC -->abcMTC XXX
iii)abcmtc mtc -->abcmtc XXX
iii)abc-mtc-zzz -->abc-XXX-zzz
iii) It would be better,if more than one space is present,all the spaces can be reduced to one space.ex abc MTC dfg -->abc XXX dfg

Hi Michael,
This will be helpful.
can you please explain this or give me a link for the documentation.
MichaelS
Check the OWA_PATTERN documentation. If there are still questions, just come back ;)
riedelme
In all these,i want to replace MTC with XXX.
Since the data is hard-coded why not just change the code replacing MTC with XXX?
Hoek
OWA_PATTERN is not documented for 9i:

http://www.oracle.com/pls/db92/db92.drilldown?remark=&word=owa_pattern&book=&preference=

but it is for 10G:

There is a good news B-)

owa_pattern is documented in Oracle9i ;-)
