Oracle text scheduling sync on single index

Question

I need to sync an oracle text index. But job fails to create:

declare
    v_job_id number(19,0);
begin
dbms_job.submit(
    JOB        => v_job_id,
    WHAT        => 'alter index NAME_IDX rebuild parameters (''sync'');',
    NEXT_DATE => SYSDATE + (1/24),
    INTERVAL    => 'SYSDATE + (1/24) + 7'
    );
end;
/

Or to run:

declare
    v_job_id number(19,0);
begin
dbms_job.submit(
    JOB        => v_job_id,
    WHAT        => 'CTX_DDL(''NAME_IDX'');',
    NEXT_DATE => SYSDATE + (1/24),
    INTERVAL    => 'SYSDATE + (1/24) + 7'
    );
end;
/

But if I run any of those works:

alter index NAME_IDX rebuild parameters ('sync');
call CTX_DDL('NAME_IDX');

Any idea of the correct syntax?

Thank you.

PD: Ive been searching, but the only answer I found doesnt fit my requirements. I also apologize for my english.

Answer 1

You can run an anonymous block, CALL is not in PL/SQL, ALTER INDEX is DDL, and you need to specify which procedure in CTX_DDL you want to run:

WHAT => 'BEGIN EXECUTE IMMEDIATE ''alter index NAME_IDX rebuild parameters (''''sync'''')''; CTX_DDL.sync_index(''NAME_IDX''); END',

However, personally I prefer to encapsulate it in a procedure (or, even better, a package) and call the procedure from the job:

CREATE PROCEDURE rebuild_name_idx IS
BEGIN
    EXECUTE IMMEDIATE 'alter index NAME_IDX rebuild parameters (''sync'')';
    CTX_DDL.sync_index('NAME_IDX');
END;
/

declare
    v_job_id number(19,0);
begin
  dbms_job.submit(
    JOB       => v_job_id,
    WHAT      => 'rebuild_name_idx;',
    NEXT_DATE => SYSDATE + (1/24),
    INTERVAL  => 'SYSDATE + (1/24) + 7'
    );
end;
/

Also, I'm pretty sure you don't actually need to rebuild the index - you only need to call CTX_DDL.sync_index to refresh it from any DML on the table.
