Bulkload.py is intended to automate the manual steps required to load the database and build indexes from scratch.
|
|
|
|
- ipcs-pat will be built if missing
|
|
- cpimport will be removed and rebuilt
|
|
- PrimProc will be stopped and started
|
|
- shared memory sgements wil be removed using ipcs-pat
|
|
- database files will be removed
|
|
- dbgen will be run with option 5
|
|
- oid files and job files will be copied to correct locations
|
|
- column data will be parsed and loaded using Job 299
|
|
- index data will be exported, sorted and loaded using Job 300
|
|
|
|
Options:
|
|
-w or --wedir= : Specify the write engine branch to use instead of the default trunk
|
|
-n or --nocache= : Specify either col or idx and the -c flag will NOT be sent to cpimport
|
|
-u or --usage : Usage message
|
|
|
|
Example:
|
|
bulkload.py -w/home/adevelop/genii/we1.1 --nocache=idx
|
|
Load the database using the we1.1 branch for writeengine and do not use cache when building indexes
