Question on PL/SQL / Insert Performance

Question

So I have a table (TABLEA) with one column that has approximately 420k records and a I have a second table (TABLEB) that stores data identified by a procedure.
I have a PL/SQL Package with the two procedures.
With the package I pass it two parameters (start and stop number).
execute id_pkg.mrs(0,10000);These numbers are used to capture information into a CURSOR like this.
I then have another procedure GET_CV that takes the value passed from emp_cur_mrs.ID and loops through each record to populate TABLEB. TABLEB is created with "NOLOGGING".
for empi_cur_mrs in
select id into v_tmpmrn from sourcemrns where id > startid  and id < endid)
loop
get_cv(empi_cur_mrs.id);
end loop;When I run this against my first 10k records it takes approximately 22 seconds to complete. As I move I continue to add more data when identifying the next 10k records (e.g. execute id_pkg.mrs(10000,20000) the performance begins to drop.
Here is the "insert" code that is stored within the GET_CV procedure.
insert /*+ APPEND */ into TABLEB(fullrec) values(v_fullrecord);Can anyone provide me with any ideas on why this could be happening?

Answer 1

Okay, this is a basic structure of what I pull and the end result of the GET_CV. I want to populate the end result into a table.
MEMBER_TBL (IDENTIFIES MEMBERS FROM ALL SOURCES; INTERNAL ID IS UNIQUE in MEMBER_TBL AND ID COULD BE SAME IN MULTIPLE SOURCES:
INTERNALID      SRCID       ID
10          100     1200
13          120     3543
14          140     1354
15          300     10980
MEMLINKED_TBL (IDENTIFIES WHICH MEMBERS ARE LINKED)
INTERNALID LINKID
10        10
13        10
14        10
15        12
MEMNAME_TBL  (NAMEID: 12=MEMBER NAME, 13=EMERGENCY CONTACT NAME, I ONLY WANT MEMBER NAME): A-active I-inactive
INTERNALID     NAMEID     NAME           STATUS          MODIFIED_KEY
10          12     SMITH,JOHN     A          222
10          12     SMIT,JON     I          099
10          13     JONES,JIM     A          222
13          12     SMITH,J          A          111
14          12     SMITH,JON     A          212
13          13     Thomas,Train     A          345The max number MODIFIED_KEY tells us the latest updated one (e.g. INTERNALID with Modified_key of 222 would be the latest for NAMEID=12)
MEMPHONE_TBL (PHONEID:11 IS HOMEPHONE AND 55=EMERGENCY PHONE)
INTERNALID     PHONEID      PHONE_AREA     PHONE_NUMBER     MODIFIED_KEY     STATUS
10          11          800          8889999          133123          A
10          11          800          8880000          000001          I
10          55          888          7729999          323431          A
13          11          888          7739999          123243          A
14          55          888          7769999          454534          AI pass the pl/sql or sql the SRCID and the ID, I then need to look at all the members linked to that one and get the lastest information.
For example, I pass it INTERNALID of '10',ID of '1200' and SRCID of '100' and expect to get back the LINKID from MEMLINKED_TBL, most recent NAME from MEMNAME_TBL and MEMPHONE_TBL.
I would get the following:
LINKID     NAME          HOMEPHONE
10     SMITH,JOHN     8008889999If I could pull this all together without passing in an "ID", that would be great. I could not figure out how without actually passing it the ID and SRCID.
Thanks for any guidance!
