为了在 DB2 中启用 SSL，我已经完成了以下链接中解释的所有过程。

之后，我使用以下命令将证书添加到 cacerts，

keytool -import -file "C:\\Program Files\\IBM\\gsk8\\bin\\keystore.arm" -alias keystore -keystore "C:\\Program Files\\Java\\jre6\\lib\\security\\cacerts"

我在代码中写了以下几行，

DB2ConnectionPoolDataSource dataSource = new DB2ConnectionPoolDataSource();
dataSource.setSslConnection(true);    
dataSource.setSslTrustStoreLocation("trust store file path");
dataSource.setSslTrustStorePassword("changeit");
PooledConnection ps = dataSource.getPooledConnection();
connection = ps.getConnection();

我收到握手异常。下面是堆栈跟踪，

    com.ibm.db2.jcc.am.DisconnectNonTransientConnectionException: [jcc][t4][2030][11211][4.16.53] A communication error occurred during operations on the connection's underlying socket, socket input stream,
