DataPump: UDE-00008 ORA-31626 ORA-39086

The following errors occur when exporting data by using DataPump:

UDE-00008: operation generated ORACLE error 31626
ORA-31626: job does not exist
ORA-39086: cannot retrieve job information
ORA-06512: at "SYS.DBMS_DATAPUMP", line 2772
ORA-06512: at "SYS.DBMS_DATAPUMP", line 3886
ORA-06512: at line 1

Check the log which shows exporting has been successful.

Master table "SYS"."SYS_EXPORT_SCHEMA_01" successfully loaded/unloaded
Dump file set for SYS.SYS_EXPORT_SCHEMA_01 is:
Job "SYS"."SYS_EXPORT_SCHEMA_01" successfully completed at 12:08:38

So it is a bug, and this error can be ignored.

How to Restrict Parallel Server Processes Running on Specific Oracle RAC Nodes

For this SQL, I want all the parallel processes running on this node or those nodes only.

All Oracle DBA knows, by default, the parallel server processes spawned to execute a SQL statement can operate on any or all Oracle RAC nodes in the cluster.

For big indexes rebuilding , a client wants all the parallel server processes running on specific node(s).

There are two easy ways to achieve this without bouncing database required.

An internal error has occurred at the agent: “java.lang.IllegalStateException: getAgentSubstitutionMap(“cluster.ClusterName”) == null”

While testing a named credential in OEM 13c by following command with errors:

Here “CLU-RACTEST” is the GI cluster name.

$emcli test_named_credential -cred_names="SEC_RACTEST" -target_name="CLU-RACTEST" -target_type="cluster"

An internal error has occurred at the agent: "java.lang.IllegalStateException: getAgentSubstitutionMap("cluster.CLU-RACTEST") == null". Check the agent's error logs for details.

Run “emctl config agent listtargets”, it shows there is no ‘cluster’ target type listed for any of the monitoring agents.

The <AGENT_INST>/sysman/log/gcagent.log showed the below errors.

2020-09-11 14:20:12,572 [631842:5A0FE62C] WARN - target cluster.CLU-RACTEST does not exist

From the OEM Console, go to Cluster homepage -> Target Setup -> Monitoring Configuration.
Click on the Update button (no need to make any other changes).

This will push the cluster target details to the agent side.

Then run “emcli test_named_credential” successfully.

$emcli test_named_credential -cred_names="SEC_RACTEST" -target_name="CLU-RACTEST" -target_type="cluster"

Credentials "SEC_RACTEST:SYSMAN" tested successfully

How to Relocate Base Directory of Oracle Enterprise Manager Agent

As per Oracle doc, upgraded OEM 12c agents to 13c with following steps:

To upgrade agents via OEM console->Manage Cloud Control ->Upgrade agents -> Agent Upgrade tasks-> ……

To clean up old agents home after upgrading via OEM console ->Manage Cloud Control -> Upgrade agents -> Post Agent Upgrade tasks -> ……

After Oracle Enterprise Manager Agents have been upgraded from 12c to 13c, the new agent binary is still under old agent base directory like “/u01/app/oracle/product/agent12g/agent_13.″.

For having a meaningful naming and future convenience, I’d like to relocate the agent base directory from “/u01/app/oracle/product/agent12g” to “/u01/app/oracle/product/agent” with following steps:
