[ORACLE] Cleanup Repository Area - Oracle Database Appliance (ODA)



Hello everyone.

How are you doing?

Today, I'll share with you a simple tip about ODA.

When I need to clean the repository area, I use these steps:

But always remember:  

  • This step-by-step worked for me, but it may not work for you.
  • It's a test environment. The real life will be different, for sure.
  • This post is for study and testing as well and has no concern for performance and security best practices.

1) List your dbhomes.

# odacli list-dbhomes



2) Check the directory size (/opt).

df -h

[ORACLE] Redo log file status are CLEARING or CLEARING_CURRENT after Restore.

Hello everyone.

Did you have this problem after restore?


Ohhh my good! WTF?

The first command "alter database open resetlogs" is abnormally abrupted leaving the redo log file status as CLEARING or CLEARING_CURRENT in controlfile.

I'll show you:

SELECT
    l.INST_ID, 
    l.THREAD#, 
    l.GROUP#, 
    substr(lf.MEMBER,1,75) as MEMBER, 
    l.SEQUENCE#, 
    l.FIRST_CHANGE#, 
    l.BYTES/(1024 * 1024) AS "Size MB", 
    l.MEMBERS, l.ARCHIVED, 
    l.STATUS, 
    lf.IS_RECOVERY_DEST_FILE, 
    l.CON_ID
FROM gv$log l
JOIN gv$logfile lf ON 
            l.INST_ID = lf.INST_ID and 
    l.GROUP# = lf.GROUP#
ORDER BY 1,2,3;



The solution is simple, but always remember:
  • This step-by-step worked for me, but it may not work for you.
  • This post is for help you, but never take my word for it, test it well before use.

Execute the clear unarchived command:
    alter database clear unarchived logfile group 1;
    alter database clear unarchived logfile group 2;
    alter database clear unarchived logfile group 3;
    alter database open resetlogs;


Here you done!



Or, you can recreate a controlfile. If you want to know more about this solution, check the note ALTER DATABASE OPEN RESETLOGS fails with ORA-00392 (Doc ID 1352133.1).

A quick and simple tip, but one that helps a lot.

[ORACLE] Batch change EDITIONABLE property.

Hello everyone.

Hope you're doing well!

Today, I have a simple case.
 
A test database had many database objects with the EDITIONABLE property set to "N".

Why did this happen? I have no idea!

Of course, you don't have any possibility to making the change manually, object by object.

This isn't a normal thing to happen, so... let's get to the solution.

A simple script solves the problem. 😆

But always remember:  
  • This step-by-step worked for me, but it may not work for you.
  • It's a test environment. The real life will be different, for sure.
  • This post is for study and testing as well and has no concern for performance and security best practices.

1) First, count the objects that will be changed.

SELECT
    substr(OWNER,1,20) AS OWNER,
    count(1) AS TOTAL,
    EDITIONABLE
FROM
    DBA_OBJECTS
WHERE
OWNER IN (
         'AUDIT_DBAMV','DBAADV','DBACP','DBADW','DBAMV',          
         'DBAPORTAL','DBAPS','DBASGU','DBATUALIZA','EDITOR','IDCE', 
         'MPACS','MVAPI','MVBIKE','MVINTEGRA','MVMOBILE','SITEDS')
AND 
OBJECT_TYPE IN (
         'FUNCTION','LIBRARY','PACKAGE BODY','PACKAGE',
         'PROCEDURE', 'TRIGGER','TYPE','TYPE BODY',
         'SYNONYM','VIEW')
AND 
EDITIONABLE = 'N'
GROUP BY OWNER, EDITIONABLE
ORDER BY OWNER, EDITIONABLE;



2) Generate the script for change.

SET SERVEROUTPUT ON;
SET PAGES 0;
SET VERIFY OFF;
SET FEEDBACK OFF;
SET HEADING  OFF;
     
SELECT 
   'ALTER '||object_type || ' ' || owner || '.' || object_name || ' EDITIONABLE;'
FROM
DBA_OBJECTS 
WHERE
OWNER IN (
         'AUDIT_DBAMV','DBAADV','DBACP','DBADW','DBAMV',          
         'DBAPORTAL','DBAPS','DBASGU','DBATUALIZA','EDITOR','IDCE', 
         'MPACS','MVAPI','MVBIKE','MVINTEGRA','MVMOBILE','SITEDS')
AND 
OBJECT_TYPE IN (
         'FUNCTION','LIBRARY','PACKAGE BODY','PACKAGE',
         'PROCEDURE', 'TRIGGER','TYPE','TYPE BODY',
         'SYNONYM','VIEW')
AND 
EDITIONABLE = 'N'
ORDER BY OWNER;

As simple as that.

But be careful. Some objects may be in heavy use at the moment, and because of this we can generate Library Cache Pin or Library Cache Lock waits - as in the image below. 
Therefore, it's important to run the script at a time when the database workload is low, monitoring the objects in use and the wait events.  



You can check the objects in the library cache using this SQL. This won't give you 100% certainty that the object is currently in use, but it's a good indicator.

SELECT 
     substr(OWNER,1,15) AS OWNER,
     substr(NAME,1,30)  AS NAME, 
     count(1) 
FROM
     GV$DB_OBJECT_CACHE 
WHERE
     NAME IN (
      'TRG_NOTA_FISCAL_CONV_PART','TRG_NOTA_FISCAL_FNFI',
      'TRG_NOTA_FISCAL_VALIDA_CNPJ','TRG_NOTA_FISCAL_PROIBE_CANC_NF',
      'TRG_NOTA_FISCAL_PARTICULAR','TRG_NOTA_FISCAL_AJUSTES',
      'TRG_NOTA_FISCAL_DADOS_NFE','TRG_NOTA_FISCAL_SN_CONTABILIZA',
      'TRG_EVOLUCAO_NOTA_FISCAL','TRG_FNFI_NF_INTEGRA_BENNER',
      'TRG_ATUALIZA_HIST_SIT_NF','TRG_STATUS_NFE_NOTA_FISCAL',
      'TRG_IMVW_OUT_NF_SUNAT')
GROUP BY OWNER, NAME;


3) Once again, count the objects with EDITIONABLE = N.



4) And count the objects with EDITIONABLE = Y.


I hope this simple tip helps you.

Mario

[ORACLE] How to move a datafile to a new location in ASM.

Hello everyone!

I hope you're doing well!

Today, I needed to move a datafile to another ASM Disk Group.

The process was simple, but remember that this step-by-step worked for me, but it may not work for you.

So do it in a test environment if you're not sure.

Important:
  • For SYS and SYSAUX, the procedure will be slightly different, so don't use this step-by-step in these two cases. 
  • There are also other ways to do this process, today I chose to do this one.
So, let's go to the party!

1) Check the datafile path
    SQL> SELECT file#, name FROM v$datafile where name like '%zab%';


2) Create a backup as copy with RMAN
    RMAN> BACKUP AS COPY DATAFILE 69 format '+DGFRA';


3) I put the datafile offline
    SQL> ALTER DATABASE DATAFILE 69 offline;


4) I switch & recover the datafile
    RMAN> switch datafile 69 to copy;
    RMAN> recover datafile 69;



5) I put the datafile online
    SQL> ALTER DATABASE DATAFILE 69 online;


6) Check the datafile in the new location 
    SQL> SELECT file#, name FROM v$datafile where name like '%zab%';


7) Delete the old datafile
    RMAN> delete datafilecopy '+DGDATA/PRD/DATAFILE/tbs_zabbix.334.1144323691';


As simple as that!

Mario

[ORACLE] ORA-16597: Oracle Data Guard Broker detects two or more primary databases. #JoelKallmanDay

Hello everyone

I hope you're doing weel.

Last week, I was doing a test using Data Guard Broker and at the end of the switchover I got the error bellow:
    
       switchover was not sucessful - Timeout

These problems in my alert.log were the main cause of the error, propably:   

LAD:2 network reconnect abandoned
<error barrier> at 0x7ffcb2af9bf0 placed krsl.c@6774
ORA-03135: connection lost contact
*** 2023-10-04 09:57:23.145275 [krsh.c:6348]

When I checked my databases - Primary and DG, the switchover was completed with success.

        select 
            inst_id, database_role, open_mode, log_mode, flashback_on, force_logging        
       from 
            gv$database;



Everything was Ok, but when I checked my DG Broker, the error bellow occurred.

        show configuration


Okay, I admit that I thought: 
I'm a smart guy, a smart DBA, an Oracle ACE, so I'm just remove the configuration and that's it! 😄

Well done!!! Emotional damage!!! I failed, miserably!!! 😅😅😅 

         remove configuration;


The solution to this was, but always remember:
  • This step-by-step worked for me, but it may not work for you.
  • It's a basic and limited environment. The real life will be different, for sure.
  • This post is for study and testing as well, and has no concern for performance and security best practices.

1)  Check the location of the DG Broker config files

show parameter dg_broker_config_file 


2) Change the dg_broker_start parameter in both environments
     
       alter system set dg_broker_start=false scope=both sid='*';

3) Remove DG Broker config files 

rm -f /u01/app/oracle/product/19.3.0.0/db_1/dbs/dr1IMANDG.dat
rm -f /u01/app/oracle/product/19.3.0.0/db_1/dbs/dr2IMANDG.dat

4) Check if the configuration was removed
       
        show configuration



5) At the end, I'll recreate the DG Broker configs
        create configuration 'DR_IM' as primary database is imandg connect identifier is ironmandg;
 
        add database ironman as connect identifier is ironman maintained as physical;

        enable configuration;



        show configuration verbose;

            Configuration - DR_IM
            Protection Mode: MaxPerformance
              Members:
              imandg  - Primary database
              ironman - Physical standby database 
              Properties:
                FastStartFailoverThreshold      = '30'
                OperationTimeout                = '30'
                TraceLevel                      = 'USER'
                FastStartFailoverLagLimit       = '30'
                CommunicationTimeout            = '180'
                ObserverReconnect               = '0'
                FastStartFailoverAutoReinstate  = 'TRUE'
                FastStartFailoverPmyShutdown    = 'TRUE'
                BystandersFollowRoleChange      = 'ALL'
                ObserverOverride                = 'FALSE'
                ExternalDestination1            = ''
                ExternalDestination2            = ''
                PrimaryLostWriteAction          = 'CONTINUE'
                ConfigurationWideServiceName    = 'ironman_CFG'
      
      Fast-Start Failover:  Disabled
      
      Configuration Status:
          SUCCESS

Yes, it's simple and work's very well!

I'm hope this post helps you.

[ORACLE] How do I upgrade the AHF.

Hello everyone!!!

I hope you're doing well!

In my last post here, I've showed how to install the Oracle Autonomous Health Framework (AHF).  

Today, I'll show how you can upgrade the AHF and how to use the auto upgrade as well.  

But always remember:

  1. This step-by-step worked for me, but it may not work for you.
  2. It's a basic and limited environment. The real life will be different, for sure.
  3. This post is for study and testing as well, and has no concern for performance and security best practices.
So, let's get started!!! 

1) Download the AHF zip file

I'll download the last version, "AHF 23.8.0 for Linux". 






Important: I'll execute all opertations with user ROOT.

2) Check the zip file

There is no need to unzip the file.



3) Check the AHF services 

tfactl print status



4) Set to stage for upgrade (if you don't run auto upgrade process)

ahfctl setupgrade -swstage /u01/AHF


Important: If you don't run the setup upgrade, you'll receive the error below:


5) Finally, I'll run the upgrade

ahfctl upgrade



6) And now, I'll check the services

tfactl print status


The upgrade process also removes the zip file from the staging area.


You can make the process easier if you configure the auto upgrade process.

If you run this setup before upgrade, you don't need to run the stage setup (step 4):

ahfctl setupgrade -all

Enter autoupgrade flag <on/off> : on
Enter software stage location : /u01/AHF
Enter auto upgrade frequency : 30
AHF autoupgrade parameters successfully updated
Successfully synced AHF configuration
refreshConfig() completed successfully.




More information about auto upgrade here.

And that's it my friends. AHF has been updated and is ready to use!!!

So, I hope this has helped.

Mario

[ORACLE] How do I install the Oracle Autonomous Health Framework (AHF)?

Hello everyone!!!

I hope you're doing well!

Today, I'll show you how to install the Oracle Autonomous Health Framework (AHF). 

I don't have an Oracle RAC installed here on my laptop, but I'll provide it. Today I'll show you a single-node environment.

I decided to write and learn a bit more about AHF after having the privilege of attending Sandesh Rao's live session at Oracle Cloudworld 2023 in Las Vegas.

First, what is Oracle Autonomous Health Framework?

In Oracle's words, it's a "Machine learning-based solution for maintaining database availability and performance".

In Mario's words, it's a "very cool tool that collects and groups your system health information and logs and uses Machine Learning to provide you insights and predictions so that you can act preventively, avoiding problems in your environment".



For more information, feel free to click.

So, let's get started!!!

But always remember:

  1. This step-by-step worked for me, but it may not work for you.
  2. It's a basic and limited environment. The real life will be different, for sure.
  3. This post is for study and testing as well, and has no concern for performance and security best practices.
1) Download the AHF zip file

In my post, I'll download version "AHF 23.7.0 for Linux". 

Calm down, calm down, buddy!!! I know we already have version 23.8 at the time of writing this post (Sep/23), but I'll show you how to upgrade the version on next post. 




2) Unzip the zip file

Important: I'll execute all installation with user ROOT.

[root@Mariao ~]# cd /u01/AHF
[root@Mariao ~]# unzip AHF-LINUX-v23.7.0.zip


3) Create the data directory.

[root@Mariao ~]# mkdir -p /AHF/Data


3) Run install.

In red, my changes and interactions.

[root@Mariao ~]# cd /u01/AHF/

[root@Mariao AHF]# ./ahf_setup
