| README for ODB tool. |
| |
| This readme will help you get started on using ODB tool. Documentation for ODB tool |
| can be found on Trafodion Wiki site |
| |
| 1. Install and configure Trafodion Linux or Windows ODBC driver |
| 2. Create a datasource for Trafodion |
| 3. LD_LIBRARY_PATH should contain both Trafodion ODB and unix odbc libraries |
| 4. Using isql, connect to Trafodion datasource |
| 3. Execute odb tool by executing 'odb64luo -h' which will display the parameters that can be |
| used to load/extract data to/from Trafodion tables |
| |
| The following env vars will have to be set: |
| export ODBCHOME=<path to ini files> |
| export ODBCSYSINI=${ODBCHOME} |
| export ODBCINI=${ODBCSYSINI}/odbc.ini |
| export AppUnicodeType=utf16 |
| export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<path to Trafodion odbc linux driver>:/usr/lib64:<path to unixodbc> |
| |
| Example table definition: |
| |
| |
| ( region_id INT NOT NULL |
| , region_name VARCHAR2(25) |
| ); |
| |
| Example map file: |
| |
| REGION_ID:IRAND:1:10000 |
| REGION_NAME:CRAND:25 |
| |
| Example commands: |
| |
| 1. For loading a table called REGIONS in schema QA with 10000 rows using 8 parallel threads and rowset size of 500: |
| |
| odb64luo -u xx -p xx -d traf -l src=nofile:tgt=TRAFODION.QA.REGIONS:map=regions.map:max=10000:rows=500:parallel=8 |
| |
| 2. To extract data from the same table: |
| |
| odb64luo -u xx -p xx -d traf -e src=TRAFODION.QA.REGIONS:tgt=regions.dat |
| |
| 3. To copy data from one table to similar table (table should exist): |
| |
| odb64luo -u xx:xx -p xx:xx -d traf:traf -cp src=TRAFODION.QA.REGIONS:tgt=TRAFODION.QA.REGIONS_COPY |
| |
