My PL/SQL block chokes on Amazon Web Service procedure. Asking for a second pair of eyes?

Hi, I have learned in the past two hours a lot of approaches that don't work. I'm asking for a fresh pair of eyes, please. Using Oracle 19c on aws rds, the rdsadmin schema is what allows SYS level commands to execute in place of the usual ALTER statements. Also, rds uses log groups in lieu of the expected log group members. I have tried many, many variations on the syntax on code that seemingly passes the TOAD and SQL*Dev syntax checkers, but it all fails to run.

DECLARE
loggroups NUMBER :=0 ;
stmt VARCHAR2(128);
BEGIN
    EXECUTE IMMEDIATE ('rdsadmin.rdsadmin_util.switch_logfile');
    SELECT count(1) INTO loggroups FROM v$log;
    IF loggroups < 9 THEN
        EXECUTE IMMEDIATE ('rdsadmin.rdsadmin_util.add_logfile(128M)');
    END IF;
END;
/

/* this works outside of the block EXEC rdsadmin.rdsadmin_util.switch_logfile; */

>>this works outside of the block EXEC rdsadmin.rdsadmin_util.switch_logfile;

why don't you just call these package procedures "directly" without using "execute immediate"?!

Correct. Execute immediate executes the 'string'. It has no idea that it is a procedure, a select, or what.

So, you would need to provide the entire command to execute immediate.

So:, something like:
EXECUTE IMMEDIATE ('begin rdsadmin.rdsadmin_util.switch_logfile; end;');

That said, don't do that!

Just provide the procedure:

...
BEGIN
    rdsadmin.rdsadmin_util.switch_logfile;
    SELECT count(1) INTO loggroups FROM v$log;
...

Missed that one entirely, tyvm. Alex, the log size is appropriate and is the default.

Glad, we could help ;-)
Btw, my question was rather about this one:

rdsadmin.rdsadmin_util.add_logfile(128M)

The parameter here (128M). What's the data type here?!

FWIW Alex, I see that at some point in this thread I dropped the delimiters -- the string value should be ('128M'). To answer your question, varchar2:

Parameter name	Data type	Default	Required	Description
bytes	positive	null	No	The size of the log file in bytes.
p_size	varchar2	—	Yes	The size of the log file. You can specify the size in kilobytes (K), megabytes (M), or gigabytes (G).

Thanks David ;-) Now this makes sense :-))
