The following PL/SQL will not execute and simply returns ‘Invalid Argument’ as an error. I’ve gone as far as commenting out eavery line one by one and I can vary the error I receive but I cannot get the proc to run as I cannot identify where the error lies and it may well lie in permissions or the executing user but any help will be received gratefully. Here’s the proc

DECLARE     ind NUMBER;             -- Loop index      h1 NUMBER;              -- Data Pump job handle      percent_done NUMBER;    -- Percentage of job complete      job_state VARCHAR2(30); -- To keep track of job state      le ku$_LogEntry;        -- For WIP and error messages      js ku$_JobStatus;       -- The job status from get_status      jd ku$_JobDesc;         -- The job description from get_status      sts ku$_Status;         -- The status object returned by get_status  BEGIN     h1 := DBMS_DATAPUMP.OPEN('EXPORT','SCHEMA',NULL,'SQL_INSTALLER_01152009_1014','LATEST');     DBMS_DATAPUMP.ADD_FILE(h1,'SQL_INSTALLER_01152009_1014.dmp','ORACLE_SCRIPT_RUNNER_BACKUP',NULL,1);     DBMS_DATAPUMP.ADD_FILE(h1,'SQL_INSTALLER_01152009_1014.log','ORACLE_SCRIPT_RUNNER_BACKUP',NULL,3);     DBMS_DATAPUMP.METADATA_FILTER(h1, 'SCHEMA_LIST','''speccs_web_test''', NULL, NULL);     DBMS_DATAPUMP.START_JOB(h1);      percent_done := 0;     job_state := 'UNDEFINED';     while (job_state != 'COMPLETED') and (job_state != 'STOPPED') loop          dbms_datapump.get_status(             h1,             dbms_datapump.ku$_status_job_error +             dbms_datapump.ku$_status_job_status +             dbms_datapump.ku$_status_wip,             -1,             job_state,             sts);          js := sts.job_status;         if js.percent_done != percent_done then              percent_done := js.percent_done;         end if;          if (bitand(sts.mask,dbms_datapump.ku$_status_wip) != 0) then              le := sts.wip;         else              if (bitand(sts.mask,dbms_datapump.ku$_status_job_error) != 0) then                  le := sts.error;             else                  le := null;             end if;         end if;          if le is not null then              ind := le.FIRST;             while ind is not null loop                  ind := le.NEXT(ind);             end loop;         end if;     end loop;     dbms_datapump.detach(h1);  END;

  1. For this particular problem it is because the schema_name speccs_web_test is not in upper case. SPECCS_WEB_TEST is fine and the proc is now running 😉
