JDBC Driver Data Source Support

Up to 4.5.x, JDBC driver implementations for data sources had some limitations, such as

not allowing users to set different connection properties, such as: securityLevel, caCertFile,

loggerType, etc. In 4.6 these data sources are removed and improved data sources are

added, as shown in the following:

by this data source

directly as normal

connections. The

Data Source internally

handles the pooling.

Do not use this data

source if your server/

middleware vendor

provides a connec-

tion pooling

implementation. This

data source is pro-

vided as a

convenience only.
