Anyone have a good way of managing output from
V$LOGMNR_CONTENTS.SQL_UNDO when the undo statements span 3 rows within
V$LOGMNR_CONTENTS?
I'm on Oracle 9.2.0.6 and need to undo about 200,000 INSERTs from last
night. Unfortunately, I'm finding that the undo statements are
sometimes near 12000 characters (4000 per SQL_UNDO x 3 rows). If I
spool the results at the UNIX level, lines > 2048 are cut in 2. If I
spool to c:\ on my laptop, sqlplus/sql*worksheet changes long, I get
4000 per line like SQL_UNDO is defined as, but even that splits in mid
column_name at times.
Here's what I'm using to grab the undo statements:
SET ECHO off FEEDBACK off HEADING off LINESIZE 4000 PAGESIZE 10000
TERMOUT off
spool undo_inserts.sql
SELECT REPLACE(sql_undo,'"')
FROM v$logmnr_contents
ORDER BY rs_id, scn;
spool off
I tried using DBMS_LOGMNR.PRINT_PRETTY_SQL when starting logmnr, but
still some lines get cutoff in mid column name.
Anyone else dealt with this (successfully)? I started playing around
with using layered SUBSTRs with INSTR on ' ', to grab 2048 of a line, up
through the next to last word, but after 34+ hrs of no sleep I'm
starting to lose it.
