Weblogic clone/ change ip of manage server



BEA-090482 - BAD_CERTIFICATE


1. Disable Flags
Put the following flags at the right places.
Node Manager: -Dweblogic.nodemanager.sslHostNameVerificationEnabled=false
Admin Server: -Dweblogic.security.SSL.ignoreHostnameVerification=true

2. Recreate the Certificates - The recommended way.
Node manager by default uses the WebLogic demo identity keystore. The keystore is generated at install time using the CertGen utility. The generated private key uses the common name (cn) resolved by Java.

2.1 Set the PATH
. $WL_HOME/server/bin/setWLSEnv.sh

2.2 Backup DemoIdentity.jks under $WL_HOME/server/lib

2.3 Generate the private key.
java utils.CertGen -cn -keyfilepass DemoIdentityPassPhrase -certfile newcert -keyfile newkey

2.4 Import the key generated above to the keystore.
java utils.ImportPrivateKey -keystore DemoIdentity.jks -storepass DemoIdentityKeyStorePassPhrase -keyfile newkey.pem -keyfilepass DemoIdentityPassPhrase -certfile newcert.pem -alias demoidentity

2.5 Copy DemoIdentity.jks to $WL_HOME/server/lib

2.6 Restart your nodemanager.

Oracle tips 2

Oracle ASM requiered packages

oracleasm-2.6.18-194.el5xen-2.0.5-1.el5.x86_64.rpm
oracleasmlib-2.0.4-1.el5.x86_64.rpm
oracleasm-support-2.1.7-1.el5.x86_64.rpm

Configuration disk for ASM
/etc/init.d/oracleasm configure
/etc/init.d/oracleasm createdisk data /dev/xvdb1

Connecting to asm from SQLPLUS
sqlplus / as sysasm

Checking ASM Groups
select g.name, d.path
from v$asm_Diskgroup g, v$asm_disk d
where g.GROUP_NUMBER=d.GROUP_NUMBER;


RMAN

Changing location of files
catalog start with '+DATA';

Checking archievelog
crosscheck archivelog all;
delete expired archivelog all;

Checking all backups
RMAN> run {
crosscheck backupset;
delete expired backupset;
}


Checking database to copy
switch database to copy;


Restoring controlfile:
restore controlfile from '/u01/app/oracle/backup/control_2012.03.28_10.44.23.0un70f5n_1_1';

Select for create new name of files
select 'set newname for datafile ' || file# || ' to ''+DATA'';' as newname
from v$datafile

Saving result to file
SYS:orclasm > save newname

Adding service name to database
alter system
set service_names='orclasm','orcl'
scope=both;

Adding listerner to database configuration
alter system
set local_listener='(ADDRESS=(PROTOCOL=tcp)(HOST=10.8.2.2)(PORT=1523))'
scope=both;

Change database unique name
alter system
set db_unique_name='orclasm'
scope=spfile;

Database restart
startup force mount


Package for undo in SQLPLUS
rlwrap-0.37-1.el5.x86_64.rpm
alias sqlplus='rlwrap -r sqlplus'
alias rman='rlwrap -r rman'


Calculating from console
echo "2147483648/1024/1024" | bc

Checking system page_size
getconf PAGE_SIZE

Recompilation binaries - turning of options
make -f ins_rdbms.mk rac_off ioracle


Opening database after unclean recovery
alter database open resetlogs;

Oracle tips

Checking from with group is runinnig instance
ORACLE_HOME\lib\config.c

Creating pfile from spfile
from sqlplus connected
create pfile from spfile

Creating instance - prepare spfile and may run database to nomount

Repair database though RMAN:
LIST FAILURE;
ADVISE FAILURE;
REPAIR FAILURE;

RMAN command
report schema
list copy of database;

catalog start with '/u01/oradata'; - changing database location


Recompiling oracle binareies without rack option
make -f $ORACLE_HOME/rdbms/ins_rdbms.mk rac_off ioracle

Relinking database
from $ORACLE_HOME/rdbms relink all

Editor from sqlplus
SQL> define _Editor=vim
SQL> ed
