Transform Service log

The Transform Service processes transformations on data sets, and also provides previews of the effects of the transformations on the data sets.

The Transform Service logs are stored in the BDD_HOME/logs/transformservice directory.

Logging the configuration

When it starts, the Transform Service logs its configuration. An abbreviated configuration entry is as follows:

16/03/22 13:41:40.151 - INFO  [LocalSparkClient@42]:- System configuration:
Number of processors available: 2
Total available memory: 502 MB
Free memory: 212 MB
Maximum available memory: 3403 MB

16/03/22 13:41:40.152 - INFO  [LocalSparkClient@50]:- Spark configuration:

spark.driver.host = 10.152.105.219

spark.local.dir = /localdisk/Oracle/Middleware/BDD-1.2.0.29.781/transformservice/tmp

...

If you are reporting a Transform Service problem to Oracle Support, make sure that this configuration is included.

Retrieving the Transform Service log

The bdd-admin script's get-logs command lets you retrieve all the BDD component logs, or just the Transform Service. For example:

./bdd-admin.sh get-logs -c transform /localdisk/logs/transform.zip

See the Administrator's Guide for information on the get-logs command.
