Use JDBC connection cache from PB component- Real's PowerBuilder Howto

This example is for a JDK1.2 or better configured Jaguar.

The latest PB build (like 10135) includes a new DLL called PBJDB70.DLL (must be in the Shared directory).
PBJDBC12.JAR (for JDK 1.2) must be in your BOOTCLASSPATH (or CLASSPATH?).
EAS3.6.1, if running as a service, you must define the following environment variable
```
      JAGUAR_JAVAVM=jdk12
```

transaction t
t = Create transaction
t.dbms  = "JDB"
t.DBParm = "UseContextObject='Yes',CacheName='jdbccachename'"
CONNECT using t;
