[Security:090482]BAD_CERTIFICATE alert was received from Hostname
javax.net.ssl.SSLKeyException: [Security:090482]BAD_CERTIFICATE alert was received from Hostname. Check the peer to determine why it rejected the certificate chain (trusted CA configuration, hostname verification). SSL debug tracing may be required to determine the exact reason the certificate was rejected.

$WL_HOME/server/bin/setWLSEnv.sh Or setWLSEnv.cmd
cd $WL_HOME/server/lib
Copy DemoIdentity.jks to another directory as backup.
then inside the WLS_HOME/server/lib run:-
Generate the private key.
java utils.CertGen -keyfilepass DemoIdentityPassPhrase -certfile newcert -keyfile newkey
Import the key generated
java utils.ImportPrivateKey -keystore DemoIdentity.jks -storepass DemoIdentityKeyStorePassPhrase -keyfile newkey.pem -keyfilepass DemoIdentityPassPhrase -certfile newcert.pem -alias demoidentity
Restart AdminConsole and Nodemanager and try to start managed server.

Timesten 15022: OraclePwd connection attribute
con1: Command> call ttgridcreate (‘samplegrid’);
15022: OraclePwd connection attribute needs to be specified and has to be non-empty for using IMDB Cache features
5109: Cache Connect general error: BDB connections not open.
As you see from the error,The OraclePWD connection attribute is not specified. which mean caching will not be enabled till you are set OraclePWD parameter , to do this reconnect with the following connection :-
connect “dsn=tt_orcldwh;uid=cacheadm;OraclePWD=cacheadm”;
Run your command again

Oracle Application Adapter installation.
The Application Adapter installer for 11g Release 1 (11.1.1.3.0) is applicable for the Oracle Service-Oriented Architecture (SOA) Suite and Oracle Service Bus (OSB). The Application Adapters that are installed can be used with Business Process Execution Language (BPEL), Mediator, Business Process Management (BPM), and OSB components. Using this installer, Application Adapters can be installed in a standalone SOA environment, standalone OSB environment, or mixed (SOA and OSB) environment.
You can check from here
The installation is not that hard , it’s all about configuration. i will post about later.
You Can Download it from here.
Operating system : Oracle Linux.
Installation Steps :-

Extend LVM Disk Linux
1- After adding New Harddisk to the server you have to ReScan The Scsi using
echo “- – -” > /sys/class/scsi_host/host?/scan
? :- Depend on you host number.
2- Use Fdisk to create new partition.
>fdisk -l
Disk /dev/sda: 107.3 GB, 107374182400 bytes

Disk /dev/sdb: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb doesn’t contain a valid partition table
Check the below :-
#fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklab el
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won’t be recoverable.The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
