Alex,    

  I don't have access to a system right now but I think x$ksmls could have the info u're looking for.    

  Thanks

I need to identify memory chunks (addresses + sizes) within large pool where certain areas are located.

I know how to do it with shared pool areas. The total area size is in X$KSMSS and chunks are in X$KSMSP:

SQL> select * from x$ksmss where KSMSSNAM = 'sql area';

ADDR           INDX    INST_ID   KSMSSLEN KSMSSNAM                     KSMDSIDX

-------- ---------- ---------- ---------- -------------------------- ----------
B70F8C88 2 1 0 sql area 0 B70F8C88 19 1 12365696 sql area 1

SQL> select * from x$ksmsp where KSMCHCOM = 'sql area' and rownum <= 10;

ADDR INDX INST_ID KSMCHIDX KSMCHDUR KSMCHCOM KSMCHPTR KSMCHSIZ KSMCHCLS KSMCHTYP KSMCHPAR

10 rows selected.

Unfortunately, I cannot find any X$ table for large pool that is similar to x$ksmsp. Large pool is managed differently than shared pool and has no LRU list for example. However, I would still expect to find large pool map somewhere. I tried to find something in X$KSMMEM but I couldn't identify there what I'm looking for.

Any suggestions are greatly appreciated.

TIA,
Alex
