How To Capture TXs From Archive Logs To Replay On 10g Database
Feb 12, 2013I am looking for a way to capture a TXs from one database and create a script or use it with tool, so we can capture TXs close to production while testing changes being implemented in database.
Env:
OS: Redhat Linux 5.0
DB: 10.2.0.4
Actually Requirement: We have active-active Golden Gate setup done for one of our DB and once a quarter we make changes in the database using DDL (CREATE / ALTER - TABLES, FUNCTIONS, TRIGGERS, etc). We are 24/7 environment and hence no downtime is affordable. What I like to know is a way to capture all TXs from one of the DB and create a script so we can run them while we are testing new changes in the database. Something like DBMS_WORKLOAD_CAPTURE Package (Available only after 11gR1) or some tools available in the market.
I also tried looking into Load Runner but felt it works with App tier than DB, I may be wrong there.

View 5 Replies View RelatedError On Table Redefinition With LOB Segments
May 25, 2012share what can we do to over come this issue?We are running 11.2.0.2 on IBM Aix. I am trying to do an redef and this is what i see:
Received an ORA-1555 error on a table redefinition with LOB segments.
ERROR at line 1:
ORA-12008: error in materialized view refresh path
ORA-01555: snapshot too old: rollback segment number with name "" too small
[code]...
As the ORA-01555 error does have a name we know that this is LOB related.We are using Automatic Undo mode and have RETENTION specifed on the LOB segments in both the source and target tables for the redefinion.The LOB segments in the source table are stored out-of-line (DISABLE STORAGE IN ROW) while the LOB segements in the target table are stored in-line (ENABLE STORAGE in row).There are a very large number of updates occuring on the source table. The table is quite large and the redefintion failed after 36 hours.
In oracle documentation we're finding conflicting information as to whether the UNDO_RETENTION database parameter affects the LOB storage RETENTION parameter, and therefore whether increasing our UNDO_RETENTION will be useful in this issue. The SQL manual indicates that it does affect this saying 'Oracle Database uses the value of the UNDO_RETENTION initialization parameter to determine the amount of committed undo data to retain in the database.'
Our current undo_retention is set to 21600.
How can we resolve this ORA-1555 error?
