ERROR: "Error occurred loading library [ cannot open shared object file" on running mappings from Informatica 10.2.1
Problem Description

While running mappings involving native connectivity to Oracle Database in Hadoop pushdown mode using Informatica 10.2.1 or later versions, execution fails with an error in loading Oracle drivers. However, the same mapping was working fine in Informatica versions before 10.2.1.


Log Trace


Error occurred loading library [ cannot open shared object file: No such file or directory]Database driver event...Error occurred loading library []]



The issue occurs when the Oracle Client library path is not included in the 'Cluster Library Path' attribute of the Hadoop connection, used for running the mapping.


Starting from Informatica 10.2.1 version, '' file would not be available in Informatica server machine. For ease of use, the configuration of all the Hadoop pushdown job settings have been moved to the 'Hadoop Pushdown connection'. As a result, all the settings can be configured directly, either from Informatica Developer client or from Informatica Administrator console. 


To resolve the issue, perform the following steps:


  1. Log into Informatica Administrator console or launch Informatica Developer client.
  2. Navigate to 'Connections' tab in case of Admin console and 'Windows > Preferences > Connections > [Domain]' , when Developer client is used.
  3. Select the 'Hadoop Pushdown' connection, being used for running the jobs.
  4. Navigate to 'Hadoop Cluster Properties' section.
  5. Edit the 'Cluster Library Path'  attribute in the section.
  6. In the 'Cluster Library Path'  attribute window, include the 'Oracle client library' location:




E.g. If the Oracle client is installed at '/databases/client_12.2.0.1/' location, then update the 'Cluster Library Path' attribute to include '/databases/client_12.2.0.1/lib' location.




   7. Once done, save the changes made to the Hadoop connection.

   8. Re-run the mapping and it should complete successfully. 


If the mapping is being executed in 'Blaze Engine' and if the 'Blaze Grid Manager Application' is already running in the Hadoop cluster, you need to restart the Blaze Engine for the changes to take effect. For more information on restarting Blaze Engine, refer to KB 521162.
