Getting ORA-28579: network error during callback from external procedure agent on executing Rscript

User13140240-OracleMar 31 2017 — edited Apr 11 2017

Hi,

We are using rqEval to call a Rscript that builds AssociationRule model

We are working on a data set with approx. 1.1k rows & 10 predictors.

After the model is built successfully and when we try load the rules we get the error.

When we give confidence & support as 0.00001, with maxRuleLength - 4 it works fine and load the rules, but when we choose maxRulelength as 10 or any high value it fails with ORA -28579 error

   

Sql Query

SELECT *
   from table(rqEval(cursor(select 1 "ore.connect" , 'DISC_WOY_15793;' as
"rhs.filter", '' as "lhs.filter" , '1805' as "model.id",'1795' as
"model.func.id",'DMModelsList' as "model.list",'IoTAppsModelsDS' as "ds.Name"
from dual),   'select cast(''a'' as varchar2(4000))
"rules", 1 as "support", 1 as "confidence", 1 as "lift", 1 as "kulc" from
dual','IOTAppsGetAssocRules'))

How can we solve the issue?

Thanks,
Pushkala
