Handling error exception in timesten

Question

how do we handle timesten specific exception in a pl/sql block.
Like TT5039...which is a exception thrown when trying to refresh a cache group using ttCacheAutoRefresh for which refresh process has already been initiated by the timesten
I require to handle it and loop till the refresh has been completed successfully so that further calculation on this refreshed data are correct.

Answer 1

I don't know your exact requirement.
Is this what you are looking for
set serveroutput on
declare
l_string varchar2(50);
begin
loop
l_string := 'call ttCacheAutorefresh(' || '''CACHEUSER''' || ',' ||'''EMP_100'''||',1)';
execute immediate l_string;
commit;
end loop;
Exception
WHEN OTHERS THEN
dbms_output.put_line(SQLERRM || ' ' || SQLCODE);
end;
TT5039: An error occurred while refreshing EMP_100: Autorefresh of specified cache group is already in progress. -57000
PL/SQL procedure successfully completed.
In this program ttCacheAutorefresh will run in a loop till it returns the error TT5039 due to autorefresh has already started bu timesten.
