Description
In TIBCO Streaming versions 10.0 and later, the data storage location for disk-based query tables should be set via the dataAreaPath property in your engine configuration file. For example..
streamBase = {
dataAreaPath = "/tmp/myDataDir"
}
For details, refer to the Help under Home > Configuration Guide > StreamBase Configuration Types > StreamBase Engine Configuration.However, versions 10.4.3 and earlier have a defect relating to the dataAreaPath. This defect is revealed to the console via the following error message..
2019-10-30 09:56:03.105440-0400 [83572:88208] ERROR com.tibco.ep.dtm.engine: (engine.cpp:216) oscdr.cpp:499: failed C++ assertion 'SW_BOMB'It is recommended that you upgraded to 10.4.4 or later to avoid this error.
Environment
All
Resolution
If it is not possible to upgrade, you may work around this error by adding a QueryTableDerbyStoreConfig configuration to your project. This can be implemented in a separate HOCON configuration file as follows:
name = "query-table-disk"
version = "1.0.0"
type = "com.tibco.ep.dtm.store.file.config"
configuration =
{
QueryTableDerbyStoreConfig =
{
adapterSettings =
{
dbName = "/path/to/disk/query/table/storage"
}
policySettings = { }
recordSettings = [ ]
}
}
The QueryTableDerbyStoreConfig remains undocumented, as the preferred approach is to upgrade to 10.4.4 or later and use the dataAreaPath property as noted above.
