Websphere Application Server to Oracle Database using TLS 1.2 – CentOS

I am trying to implement TLS 1.2 from Websphere Application Server v9.0.5.6 to Oracle 19c Database. Both the WAS and Oracle are on different Virtual Machines running on Centos 7. Used Websphere provided IBM Java 8 and Oracle provided ojdbc8.jar (from Oracle 19c Client). Non-ssl connection is working fine from WAS console.

I have done the following to implement TLS 1.2.

  1. Used this link and completed the Oracle Database side SSL configuration. For testing I even made the client side configuration on WAS vm and tested using sqlplus (with oracle user and oracle 19c client) and I was able to connect and get TCPS as provided in this query.
  2. Then I added the Oracle DB self-signed certificates to ‘WAS_HOME/AppServer/profiles/AppSrv01/etc/trust.p12’. I used iKeyman for adding the DB certificate to WAS. Then added the custom property in datasource
    ‘connectionProperties’ with values javax.net.ssl.trustStore=WAS_HOME/AppServer/profiles/AppSrv01/etc/trust.p12; javax.net.ssl.trustStoreType=PKCS12; oracle.net.ssl_version=1.2; javax.net.ssl.trustStorePassword=***
  3. Instead of point 2, I also tried JKS. Added the Oracle DB self-signed certificates to ‘WAS_HOME/AppServer/java/8.0/jre/lib/security/cacerts’. I used iKeyman for adding the DB certificate to WAS. Then added the custom property in datasource ‘connectionProperties’ with values javax.net.ssl.keyStore= WAS_HOME/AppServer/java/8.0/jre/lib/security/cacerts; javax.net.ssl.keyStoreType=JKS; oracle.net.ssl_version=1.2; javax.net.ssl.keyStorePassword=***

I enabled the debug logs and in both the scenarios I am getting the error ‘java.security.SignatureException: Signature length not correct: got 128 but was expecting 256’

Can anyone pls suggest on the error or how TLS 1.2 from WAS to Oracle DB can be successfully achieved?

    Steps

    1. Following is my setup, though setup should not make a difference for achieving TLS 1.2.
      WAS v9.0.5.6 on Centos VM1. WAS installed with ‘user1’. Used Websphere provided IBM Java 8.
      Oracle Client 19c on same Centos VM1. Oracle client installed with ‘oracle’ user.
      Oracle Database 19c on Centos VM2. Database installed with ‘oracle’ user.

    2. Used this link to complete the server and client side certificate configuration. Generated and exchanged the self-signed certificates on/between server and client as given in the instructions. For testing keep the password free from special characters. I have seen issues when password contains special characters.

    3. On Oracle Client host (Centos VM1 for me) convert Oracle PKCS12 to Java Key Store. I used the below command with ‘oracle’ user.

      orapki wallet pkcs12_to_jks -wallet "/home/oracle/wallet" -pwd abcd123 -jksKeyStoreLoc "/home/oracle/jkswallet/ewallet.jks" -jksKeyStorepwd abcd123

    4. Change the permission of “home/oracle/jkswallet” and “home/oracle/jkswallet/ewallet.jks" to 755 so that its accessible for ‘user1’ running WAS on same server.

    5. On WAS create a normal ‘JDBC provider’ using ojdbc8.jar. No other jar is needed. Create a ‘Data source’ using the earlier created JDBC provider. Along with Data source also create ‘JAAS - J2C authentication data’ for username and password.

    6. I used the following url format in ‘Data source’

      jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCPS)(HOST=172.16.77.11)(PORT=2484)))(CONNECT_DATA=(SERVICE_NAME=PROD01PDB)))

    7. Add a property in the ‘Custom properties’ under your ‘Data Source’
      Name: connectionProperties
      Value: javax.net.ssl.keyStore=/home/oracle/jkswallet/ewallet.jks; javax.net.ssl.keyStoreType=JKS; javax.net.ssl.keyStorePassword=abcd123; javax.net.ssl.trustStore=/home/oracle/jkswallet/ewallet.jks; javax.net.ssl.trustStoreType=JKS; javax.net.ssl.trustStorePassword=abcd123; oracle.net.ssl_version=1.2; oracle.net.ssl_server_dn_match=false
