SOLUTION:

I have been discussing this with LDC and agree the better solution is to TRUNCATE the partition.

How To Avoid ORA-14758 in Interval Partitioned Table (Doc ID 1526571.1)
(iv) Temporarily disable the interval partition.

Here is one example of Temporarily disable the interval partition.
This has side effects as shown which has worked until one day it stopped working.
Test cases are simple and real world may not be as such.

Just a crazy idea.
Keep the same backup tag for all backups until the next level 0.

Backup TAG for daily level 0 backup:

[oracle@db-fs-1 ~]$ echo "$(date +%Y%b%d)"
2020Feb19
[oracle@db-fs-1 ~]$

Backup TAG for weekly level 0 backup

[oracle@db-fs-1 ~]$ echo "$(date +%Y%b)_WK$(date +%U)"
2020Feb_WK07
[oracle@db-fs-1 ~]$

Backup TAG for monthly level 0 backup

[oracle@db-fs-1 ~]$ echo "$(date +%Y%b)"
2020Feb
[oracle@db-fs-1 ~]$

Tag: ARCH for archivelog backup and may not be useful.
LV=A means archivelog backup.

Find Database Growth Using OEM Repository

Filed under: 12.2,oracle — mdinh @ 2:20 pm

Typically, what as been done is to schedule job for each database to collect database growth.

This may be problematic as it can be forgotten when new databases are created versus the likelihood of forgetting to add database to monitoring for OEM.

EM12c, EM13c : Querying the Repository Database for Building Reports using Metric Information (Doc ID 2347253.1)

Those raw data are inserted in various tables like EM_METRIC_VALUES for example. 
EM aggregates those management data by hour and by day. 
Those raw data are kept 7 days; the one hour aggregated data are kept 31 days, while one day aggregated data are kept one year.

How to obtain the Historical Database Total Used and Allocated Size from OEM Repository

The above blog post provided a good starting point.

This post is using query to collect database size (metric_name=’DATABASE_SIZE’) vs tablespace size (metric_name=’tbspAllocation’) to avoid having to sum all tablespaces to determine database size.

OMS: 13.2.0 and EMREP DB: 12.2.0

Comparison for METRIC_COLUMN between DATABASE_SIZE and tbspAllocation.

For tbspAllocation, the size was not clear and did not research further but it does appear to be GB.

SQL> select distinct metric_name, METRIC_COLUMN from sysman.mgmt$metric_daily where metric_name='tbspAllocation' order by 1;

ReCreate ASM Disks RAC

Filed under: 12.2,ASM — mdinh @ 3:01 pm

A long time ago I had written about ReCreate ASM Disks; however this was single instance.

Basically, need to duplicate 11.2.0.4 database to 12.2 RAC. Unfortunately, compatible.rdbms=12.1.0.2.0.

alter diskgroup DATA set attribute ‘compatible.rdbms’ = ‘11.2’ does not work.

You are thinking, “Why not create with 11.2 to start with?”

I am using oravirt (Mikael Sandström) · GitHub to build RAC environment.

This is the best, hands down resource to build sand box and unfortunately for me, have not figured out how to configured all the details.

NOTE: This is a newly created environment and does not contain any database.

Goldengate 12.3 Automatic CDR

Filed under: 12.2,GoldenGate,oracle — mdinh @ 11:51 pm

Automatic Conflict Detection and Resolution

Requirements: GoldenGate 12c (12.3.0.1) and Oracle Database 12c Release 2 (12.2) and later.

Automatic conflict detection and resolution does not require application changes for the following reasons:

  • Oracle Database automatically creates and maintains invisible timestamp columns.
  • Inserts, updates, and deletes use the delete tombstone log table to determine if a row was deleted.
  • LOB column conflicts can be detected.
  • Oracle Database automatically configures supplemental logging on required columns.

I have not had the chance to play with this yet and just only notice the documentation has been updated with details.
