SSL Connection Over JDBC for Oracle

Create Certificate

The steps demonstrated here are performed on a Windows DB2 machine version 11.5.

Before proceeding, ensure that GSKit lib is added to the PATH variable.

1. Create a key database and configure your digital certificates.

   gsk8capicmd_64 -keydb -create -db "mydbserver.kdb" -pw "changeit"  -stash
   

2. Add the certificate for the server to the key database.

   gsk8capicmd_64 -cert -create -db "mydbserver.kdb" -pw "changeit" -label "myselfsigned" -dn "CN=myhost.mycompany.com O=myOrganization, OU=myOrganizationUnit,L=myLocation,ST=ON,C=CA"
   

3. Extract the certificate to a file.

   gsk8capicmd_64 -cert -extract -db "mydbserver.kdb" -pw "changeit" -label "myselfsigned" -target "mydbserver.arm" -format ascii -fips
   

4. Set up SSL support.

   db2 update dbm cfg using SSL_SVR_KEYDB  "C:\Program Files\IBM\gsk8\bin\mydbserver.kdb"
   db2 update dbm cfg using SSL_SVR_STASH "C:\Program Files\IBM\gsk8\bin\mydbserver.sth"
   db2 update dbm cfg using SSL_SVR_LABEL myselfsigned
   db2 update dbm cfg using SSL_SVCENAME 50443
   db2 update dbm cfg using SSL_VERSIONS TLSv12
   

5. Add the value SSL to the DB2COMM registry variable.

   #bash
   db2set -i db2inst DB2COMM=SSL,TCPIP
   

   Note

   Replace db2inst with your db2 instance

6. Restart DB2 instance.

    db2stop, db2start
   

7. Verify SSL parameter.

   Field	Description
   Name	Unique name for certificate.
   Certificate	Content of the cert.txt file in .PEM format.

4. Click Upload.

The SSL setup is complete. You can now create database connection over SSL.

CipherTrust Manager's Rest interface
