XAER_RMERR : A resource manager error has occured in the transaction branch oracle.jdbc.xa.OracleXAException

========================================================================
Applies To:
WLS - 10.3.6.0.11
OSB - 11.1.1.7.4
========================================================================
Problem:
We are not able to dequeue messages from AQ becuase of XAER_RMERR : A resource manager error has occured in the transaction branch oracle.jdbc.xa.OracleXAException.
If the server is restarted, it will work fine for some time. Then the exception will occur again and service stops working.

Error:
Unexpected exception while enlisting XAConnection java.sql.SQLException: XA error: XAResource.XAER_RMERR start() failed on resource 'testDS': XAER_RMERR : A resource manager error has occured in the transaction branch  oracle.jdbc.xa.OracleXAException

========================================================================
Cause:
WLS is not cleaning pending XA transactions.

========================================================================
Resolution:
We need to prepare the database for XA.Please execute below steps on DB.
connect to database as SYS user
@xaview.sql  ,the xaview.sql script resides in the $ORACLE_HOME/rdbms/admin directory
grant all on dba_2pc_pending to public;
grant all on dba_pending_transactions to public;
grant all on dba_2pc_neighbors to public;
grant select on pending_trans$ to public;
grant select on v$xatrans$ to public;

If the above steps are not performed on the database server, normal XA database queries and updates may work fine. However, when the Weblogic Server Transaction Manager performs recovery on a re-boot after a crash, recover for the Oracle resource will fail with XAER_RMERR. Crash recovery is a standard operation for an XA resource.

Also check for inactive sessions and CPU on DB side. If there are any inactive sessions clear them.
Rule for XA timeout is Global JTA Timeout (at WebLogic server level) < XA Transaction Timeout (at Data Source level) < DISTRIBUTED_LOCK_TIMEOUT (parameter in the Database)

Resolution:
We need to apply same WLS patches to managed server host as like admin server and restart the server.
This should resolve your issue.

BAD_CERTIFICATE alert was received (java.lang.RuntimeException: Cannot convert identity certificate)

========================================================================
Applies To:
WLS - 10.3.6

Services which are having HTTPS/SSL endpoints aren't working properly.

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.>

Reason:
java.lang.RuntimeException: Cannot convert identity certificate
========================================================================
Cause:
Recently target system renewed their certificates and new certificates installed on downstream side which has SHA256RSA signature algorithm and old certificates were having SHA1RSA which was working fine.
Weblogic is having default SSL implementation(CERTICOM)
========================================================================
Resolution:
We need to enforce weblogic server to use JSSE if any cipher suite is unsupported by default SSL implementation(CERTICOM).
To change SSL implementation from CERTICOM to JSSE and resolve issue kindly follow below steps,
1. Navigate Environment -> servers -> [server name] -> Configuration -> SSL -> Advanced tab -> Enable Use JSSE SSL
2. Also we need to import new root and intermediate certificates from renewed cert if they aren't existed in CACERT
Login to each domain host and perform below,
cd $JAVA_HOME/jre/bin
To list CACERTS, use below command,
keytool -list -v -keystore $JAVA_HOME/jre/lib/security/cacerts
To import cert, kindly use,
./keytool -import -alias alias_name -keystore $JAVA_HOME/jre/lib/security/cacerts -trustcacerts -file $Cert_location/cert.pem
3. Restart servers for changes to take effect and test the service.

$Domain_home/config/fmwconfig/jps-config.xml file was still referring to old DB URL. Change this to new DB URL

========================================================================
Cause: 
Thread Local Area (TLA) size for object allocation is not sufficient.
========================================================================
Resolution:
We need to fine tune thread-local areas (TLA) for object allocation in JRockit as per application requirement. Sometimes default settings might not work expected.
-XXtlaSize option sets the thread-local area size,
Usage:
-XXtlaSize:min=size,preferred=size,wasteLimit=size

Default TLA settings were,
min=2k
preferred=16k
wasteLimit=1k

Below settings resolved OOM issue in my local environment and have seen performance improvement as well.
We can configure it as startup arguments,
-XXtlaSize:min=8k,preferred=512k,wasteLimit=8k

Restart the server for changes to take effect.
