Hibernate DB2 no Mainframe

Boa tarde pessoal

estou com o seguinte problema estou começando um projeto e nele utilizo o hibernate para se conectar ao banco de dados DB2.

quando me conecto no DB2 da baixa, consigo fazer todas as operações de CRUD. Só que o projeto mau saiu do papel e já existe uma mudança, não teremos mais o DB2 na baixa e sim na ALTA(Mainframe). Gostaria de saber se alguém já trabalhou com o hibernate se conectando no Mainframe.

Estou utilizando o arquivo de licença para poder acessar o mainframe.

Até ai blz eu consigo acessar o banco de dados de boa, mais quando tento fazer alguma funcionalidade do CRUD ele sempre retorna o erro. Será que alguem já passou por isso ou sabe me dizer como resolver o problema? Lembrando que quando eu redireciono para o DB2 da baixa ele funciona normalmente sem nenhum tipo de alteração no código.

Erro
