In this article, we will identify some of the possible causes that can cause oracle error 31623 and then show several ways to resolve it.
I received the following error message: “ORA-31623: task could not be attached to this session when the specified handle is displayed – an error occurred while migrating the Oracle database”.
A Job That Is Not Associated With This Session Via The Selected Handle
This ORA-31623 error is related to an attempt to refer to an ideal job using a handle that may or may not be valid for the current session lookup.
Change system position of streams_pool_size

Follow all the steps below to troubleshoot and resolve this issue to:
Step the problem, 1. First check the value of STREAMS_POOL_SIZE in the database:
Connect or as sysdbaShow streams_pool parameterselect * away V$sgainfo; from... the poolStream Size 0 Yes
If Zu streams_pool_size is small, the Data Pump job will fail. This is trueIt can also happen when you are using Auto Shared Management Memory (ASMM) or Automatic Management Memory (AMM) space and there is not enough memory to increase STREAMS_POOL_SIZE.
Settings for manual STREAMS_POOL_SIZE 128M 64M, or even 256M should be successful.
Increase (also for sga_target ASMM) or memory_target AMM), (to show more free memory available when configuring automatic SGA components.
To avoid this error, you need to set up a datapump database with a thread pool.
Set the STREAMS_POOL_SIZE ALTER manually (using SYSTEM or by changing my value to PFILE/SPFILE), restart the database and retry Pump’s Data Export.
Step 2: Check for a possible invalid data line object:
connect / as sysdbaView water settingsadmin pass A10name for object column for a30built-in kupc$datapump_quetab parsing, cascading structure check;parse desktop kupc$datapump_quetab_1, check cascading structure;Select object id, owner, object name and reputation from dba_objects. where is the volume namethe one in 'kupc$datapump_quetab%';as string SetColumn status 100 for a9col object_type if it is equal to a20;owner col.object for a50title, object id, select owner ||' object, type.'||object name "OWNER.OBJECT"from dba_objectswhere the name of the object is ordered as "%DATAPUMP_QUETAB%" in accordance with 3 p.4;
If invalid queuing objects exist here, data pumping will not work. This usually results in an error in the Alert.log file:
ORA-00600: error code rrnner, args: status], [kwqbgqc: below average , , , , , For , for more details and full completion, see:Note 754401.1 bug - ORA-31623 ORA-600 resulting in status [kwqbgqc: Incorrect] when exporting or importing DataPump
Step 3. Check invalid (CATALOG, CATPROC, JAVAVM registry components) and invalid used objects:
connect system / as sysdbaSet 90 linesmap a12 passcol for comp_id for a8col, specifically the schema versioncol comp_name a35 formatColumn state for a12select comp_id,schema,status,version,comp_name from dba_registry, sell for 1;Set 120 linescol status is for a9object type col for a20;col owner.to a50select object status, owner||' object_id, object type, .'||object name "OWNER.OBJECT" directly from dba_objects where status != 'REAL' and owner = 'SYS' and object_name is not comparable to Commander 'bin$%' after 4.2;
If the registry components of the CATPROC directory and/or JAVAVM and/or objects such as SYS.KUPW$WORKER or SYS.KUPP$PROC are not valid, the pump job will necessarily fail.
To fix this, reload the Data Pump into the database:
connect /see as start sysdba-- spool to file:pinwheel catset queues 120 numwidth 12 sides 10 $.000 long 2000000000Change session set HH24:MI:SS';Show user nls_date_format='yyyy-mm-ddselect system date from double;immediate stop-- 9.2, usage: boot migrationTransfer of [email protected]?/rdbms/admin/[email protected]?/rdbms/admin/[email protected]?/rdbms/admin/utlrp.sqlrelaxscroll down the registry-- Record status:together 90collar line drawing for a12col comp_id for a8col another schema versioncol not comp_name a35 formatauthoritative pass for a12select comp_id,schema,status,version,comp_name from dba_registry, from received Objects 1;-- invalid:Patch set 120Column status for a9object type collar fits a20;owner of col.objectI a50select status, object_id, enter object owner, ||'.'||object name "OWNER.OBJECT" by dba_objects where the status is !

Step 4. Check if _FIX_CONTROL is set for error 6167716:
connect - as sysdbaShow parameter of this _fix_control
If a storage option is set, the data transfer job will fail.

step. If Data Job Water is started by a package, check if the package was created and the caller’s permissions (AUTHID clause):
connect / just because sysdbaOffer lines 120 Number width 12 sheets 10000 2000000000col lang ddl lot for a100select dbms_metadata.get_ddl('PACKAGE','
',' ') "DDL" from double;
If the instant package appears to have been created with a summoner, the data load task may fail when run from that type of package.Download the software to fix your PC by clicking here.
