Have a new issue with xplan.

Running against v11.1 linux rh5 with multibyte characterset:
NLS_NCHAR_CHARACTERSET AL16UTF16
NLS_LENGTH_SEMANTICS CHAR

( I have a hunch the issue is related to the characterset because xplan works fine against another v 11.1 db)

Issued: @xplan “” “” (have tried different options, same results)
get this:

new 147: :OPT_ASH_PROFILE_MINS := 15;
old 148: &COMM_IF_LT_10G. end if;
new 148: end if;
declare /* xplan_exec_marker */ — process options
*
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 28

SQL>
SQL> — print current options values

SQL> begin

3 ‘inst_id=’ || :OPT_INST_ID
4 || ‘ plan_stats=’||:OPT_PLAN_STATS

Any ideas?

I’m happy to see that you find xplan useful and that you are so kind in letting me know :)

I have added your suggestion in the header of xplan.sql and I have also expanded the example description
a bit more – it is indeed possible to add full expressions in the order-by list, provided that you turn
commas into semicolons:

– order_by: (default: null)
– Order statements by the specified columns/expressions. Ties are ordered by sql_text and child_number.
– Use the semicolon instead of the comma in expressions.
– For example: “order_by=elapsed_time desc;buffer_gets”
– “order_by=elapsed_time/decode(executions;0;null;executions) desc;buffer_gets”

This is useful also in your scenario, since it happens far too often that you get an executions=0 row, and
all it takes to spoil the fun is just one row ;)

I’ve chatted before with you about your xplan routine.

I’ve been using it some more and I read your documentation again.
I learned by trial and error that I could get it to sort the output by execution time per execution.
Here is what I used:
@xplan “%” “parsed_by=ONEADMIN,order_by=elapsed_time/executions desc”

If you are so inclined you may want to add this sort option to your samples.

Thanks for the xplan routines, I am finding them more useful. We have the sql tune / addm big dollar utilities. I find good info in your output that does not show up with addm report.

thanks for writing a such a beautiful script, I can’t say. how useful it was for me ..

Rich ..

can you tell me :

- the version of the database you are connecting to
- the version of sqlplus you are using

The most recent the version of sqlplus, the better; I usually use 11.2 to connect even to older databases.

but no luck ..any suggestions ..

@xplan “” “sql_id=akwwmt0txutp3″

Rich ..

a) are you using a recent version of sqlplus (e.g. 10g, 11g) ?

b) have you extracted all the files contained in xplan.zip in the current directory ?

regards
Alberto

used all option but no luck ..

@xplan.sql “%select jp.cp_job_id%” “”

@xplan.sql “” “sql_id=ab4rjccnt8dvx”

@xplan.sql “” “sql_id=ab4rjccnt8dvx,hash=697579389″
