| Sample JDBC connector dbms writer and reader topology applications. |
| |
| The following configuration is assumed: |
| - Apache Derby is installed and the environment variable DERBY_HOME is set |
| |
| The writer is a simple JDBC connector sample demonstrating |
| streaming write access of a dbms to add stream tuples to a table. |
| |
| The reader is a simple JDBC connector sample demonstrating |
| streaming read access of a dbms table and creating stream |
| tuples from the results. |
| |
| The source code for the samples is in the <edgent-release>/samples directory. |
| |
| Running the simple sample |
| ------------------------- |
| |
| Modify the jdbc.properties file if required. |
| |
| # run the simple sample writer |
| # the writer runs briefly and prints out additions to the table |
| $ ./runjdbcsample.sh writer |
| Inserting into persons table: person id=1 first=John last=Doe |
| Inserting into persons table: person id=2 first=Jane last=Doe |
| Inserting into persons table: person id=3 first=Billy last=McDoe |
| $ |
| |
| # run the simple sample reader |
| # the reader runs briefly and prints out retrieved info |
| $ ./runjdbcsample.sh reader |
| retrieved person: id=1 first=John last=Doe |
| retrieved person: id=2 first=Jane last=Doe |
| retrieved person: id=3 first=Billy last=McDoe |
| Unknown person id=99999 |
