ReCreate ASM Disks RAC

Sun, 2018-08-05 10:01

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.

Patching GoldenGate with DBFS

Fri, 2018-07-20 18:41

There seems to be no consistency as to what directories should be on DBFS for when GoldenGate is implemented with RAC.

Here I will share my thoughts based on issues encountered.

Here are errors when applying GoldenGate Patchset.

The errors were due to the stack being down from after running opatchauto apply -norestart which results in DBFS offline for the instance.

Errors can be avoided if directories are local as they should be.

Use Oracle RAC database as a baseline.
Are alert logs, trace files, etc… on shared volume if Oracle software is installed locally?

Playing With Service Relocation 12c

Thu, 2018-07-19 09:14
With 12c, use verbose to display services running.
[oracle@racnode-dc1-1 rac_relocate]$ srvctl -V
srvctl version: 12.1.0.2.0

[oracle@racnode-dc1-1 rac_relocate]$ srvctl status database -d hawk -v
Instance hawk1 is running on node racnode-dc1-1 with online services p11,p12,p13,p14. Instance status: Open.
Instance hawk2 is running on node racnode-dc1-2 with online services p21,p22,p23,p24,p25. Instance status: Open.

[oracle@racnode-dc1-1 rac_relocate]$ srvctl status instance -d hawk -i hawk1 -v
Instance hawk1 is running on node racnode-dc1-1 with online services p11,p12,p13,p14. Instance status: Open.

[oracle@racnode-dc1-1 rac_relocate]$ srvctl status instance -d hawk -i hawk2 -v
Instance hawk2 is running on node racnode-dc1-2 with online services p21,p22,p23,p24,p25. Instance status: Open.

There is option to provide comma delimited list of services to check the status.
Unfortunately, option is not available for relocation which I failed to understand.
[oracle@racnode-dc1-1 rac_relocate]$ srvctl status service -d hawk -s "p11,p12,p13,p14"
Service p11 is running on instance(s) hawk1
Service p12 is running on instance(s) hawk1
Service p13 is running on instance(s) hawk1
Service p14 is running on instance(s) hawk1

[oracle@racnode-dc1-1 rac_relocate]$ srvctl status service -d hawk -s "p21,p22,p23,p24,p25"
Service p21 is running on instance(s) hawk2
Service p22 is running on instance(s) hawk2
Service p23 is running on instance(s) hawk2
Service p24 is running on instance(s) hawk2
Service p25 is running on instance(s) hawk2

Puzzled that status for services is able to use delimited list where as relocation is not.

I have blogged about new features for service failover: 12.1 Improved Service Failover

Another test shows that it’s working as it should be.

[oracle@racnode-dc1-1 ~]$ srvctl status database -d hawk -v
Instance hawk1 is running on node racnode-dc1-1 with online services p11,p12,p13,p14. Instance status: Open.
Instance hawk2 is running on node racnode-dc1-2 with online services p21,p22,p23,p24,p25. Instance status: Open.

[oracle@racnode-dc1-1 ~]$ srvctl stop instance -d hawk -instance hawk1 -failover

[oracle@racnode-dc1-1 ~]$ srvctl status database -d hawk -v
Instance hawk1 is not running on node racnode-dc1-1
Instance hawk2 is running on node racnode-dc1-2 with online services p11,p12,p13,p14,p21,p22,p23,p24,p25. Instance status: Open.
[oracle@racnode-dc1-1 ~]$


[root@racnode-dc1-1 ~]# crsctl stop crs
[root@racnode-dc1-1 ~]# crsctl start crs


[oracle@racnode-dc1-1 ~]$ srvctl status database -d hawk -v
Instance hawk1 is not running on node racnode-dc1-1
Instance hawk2 is running on node racnode-dc1-2 with online services p11,p12,p13,p14,p21,p22,p23,p24,p25. Instance status: Open.
[oracle@racnode-dc1-1 ~]$

[oracle@racnode-dc1-1 ~]$ srvctl start database -d hawk

[oracle@racnode-dc1-1 ~]$ srvctl status database -d hawk -v
Instance hawk1 is running on node racnode-dc1-1. Instance status: Open.
Instance hawk2 is running on node racnode-dc1-2 with online services p11,p12,p13,p14,p21,p22,p23,p24,p25. Instance status: Open.
[oracle@racnode-dc1-1 ~]$

However, the requirement is to relocate services versus failover.

Here are scripts and demo for that.

Script will only work for 2-nodes RAC and service is running on 1 instance only.

[oracle@racnode-dc1-1 ~]$ srvctl config service -d hawk |egrep 'Service name|instances'
Service name: p11
Preferred instances: hawk1
Available instances: hawk2
Service name: p12
Preferred instances: hawk1
Available instances: hawk2
Service name: p13
Preferred instances: hawk1
Available instances: hawk2
Service name: p14
Preferred instances: hawk1
Available instances: hawk2
Service name: p21
Preferred instances: hawk2
Available instances: hawk1
Service name: p22
Preferred instances: hawk2
Available instances: hawk1
Service name: p23
Preferred instances: hawk2
Available instances: hawk1
Service name: p24
Preferred instances: hawk2
Available instances: hawk1
Service name: p25
Preferred instances: hawk2
Available instances: hawk1
[oracle@racnode-dc1-1 ~]$
DEMO:
[oracle@racnode-dc1-1 rac_relocate]$ ls *relocate*.sh
relocate_service.sh  validate_relocate_service.sh

[oracle@racnode-dc1-1 rac_relocate]$ ls *restore*.sh

How To Delete Integrated Extract Replicat

Fri, 2018-07-13 19:46

Why is this important?

If processes are not unregistered from database, they are orphaned.

Hence:
unregister replicat $replicat_name DATABASE
unregister extract $extract_name DATABASE

Oracle Cloud Orchestration

Sat, 2018-06-09 08:57

Oracle Cloud has a pretty cool concept (Orchestration) to recreate an instance; however, it’s all hard coded.
The orchestration cannot be shared with some else to create the configuration with different name or from different account.
What version is the Orchestration and shouldn’t it be in the metadata.

Using Postman For REST API on Oracle Cloud Infrastructure

Mon, 2018-05-28 10:21

Just completed quick training for Oracle Cloud Infrastructure (OCI)

REST API can be used on OCI for automation and presentation.

I find presentation for JSON results from CLI on server is UGLY.

Finally, I found POSTMAN which does to very nice job of presentation.

POSTMAN has results history, command history, search function.

Using GoldenGate LogDump To Find Bad Data

Thu, 2018-05-17 23:38

GoldenGate Primary Extract from source database captured data without any issues;

however, target was not able to consume the data since GoldenGate process would ABEND.

Unfortunately, I cannot provide all the details but high level.

For database, NLS_LENGTH_SEMANTICS=BYTE; hence, 800 characters should equal 800 bytes. 
However, one character is most likely a multi-byte character which target cannot consume 
as it is not able to handle multi-byte.
  

Goldengate REPORTING P2

Mon, 2018-05-14 21:35

Previous post for Goldengate REPORTING

Goldengate reporting has to be the least implemented functionality until it is needed and often in hindsight.

Here is an example of what I would normally implement.

STATOPTIONS RESETREPORTSTATS
REPORT AT 00:01
REPORTROLLOVER AT 00:01
REPORTCOUNT EVERY 15 MINUTES, RATE
DISCARDROLLOVER AT 00:01 ON SUNDAY

If business only cares about monthly data, then would not make sense to collect daily nor would it make sense for business to request such.

DataGuard Convention

Fri, 2018-05-11 06:58

Good convention and implementation make life and automation so much simpler and more time for golfing.

I have seen some really poor and really good implementation and here’s a good one.

Wish I can take credit for it and unfortunately I cannot.

The scripts were created by whoa.

Scripts an be run from primary or standby for any instances provided profile to source database environment exists on host.

Use ORACLE_UNQNAME for DataGuard Environment

How to cleanup DBFS tablespace after removing files at DBFS filesystem (Doc ID 2331565.1)	
====================================================================================================
High level overview of the DBMS_DBFS_SFS.REORGANIZEFS procedure:
----------------------------------------------------------------------------------------------------
1) Create a NEW tablespace
2) Create a temporary filesystem with dbms_dbfs_sfs.createFilesystem in the new tablespace.
3) Run dbms_dbfs_sfs.reorganizeFS -->>
   EXEC DBMS_DBFS_SFS.REORGANIZEFS(SRCSTORE=>'FS_FS1', DSTSTORE=>'FS_TMP_FS');
4) The dbfs data is now in the smaller NEW tablespace.
5) Drop the temporay filesystem with dbms_dbfs_sfs.dropFilesystem
6) The OLD original tablespace is empty now.
----------------------------------------------------------------------------------------------------
To reuse the same tablespace again please follow the below steps
----------------------------------------------------------------------------------------------------
7) Create a temporary filesystem with dbms_dbfs_sfs.createFilesystem in the OLD ORIGINAL tablespace.
8) Run dbms_dbfs_sfs.reorganizeFS
9) The dbfs data is now in the smaller the ORIGINAL tablespace.
10) Drop the temporay filesystem with dbms_dbfs_sfs.dropFilesystem
11) The NEW small tablespace is empty now and can be dropped.

====================================================================================================
DBFS tablespace keep growing not using expired blocks (Doc ID 2327299.1)	
====================================================================================================
----------------------------------------------------------------------------------------------------
First perform the DBFS re-org to cleanup the tablespace after removing the files at file system level by following below document
----------------------------------------------------------------------------------------------------
How to cleanup DBFS tablespace after removing files at DBFS filesystem (Doc ID 2331565.1)

----------------------------------------------------------------------------------------------------
After the re-org, set the  below parameter to reuse the expired blocks
----------------------------------------------------------------------------------------------------
ALTER SYSTEM SET "_ENABLE_SPACE_PREALLOCATION" = 0;

====================================================================================================
ORA-1654 - DBFS FREE SPACE NOT RECLAIMED AFTER CLEARING FILES (Doc ID 1948305.1)	
====================================================================================================
----------------------------------------------------------------------------------------------------
a) Check Lob retention setting:
----------------------------------------------------------------------------------------------------
  ex. SQL> select 
  table_name,retention_type,retention_value,retention,securefile from dba_lobs 
  where table_name = 'T_FS1';

----------------------------------------------------------------------------------------------------  
b) Change LOB retention to none.
----------------------------------------------------------------------------------------------------
  ex. SQL> alter table DBFS_USER.T_FS1 modify lob (FILEDATA) (retention none);

After countless discussions, team found GOLD.

12.1 Shrinking and Reorganizing DBFS Filesystems STEPS:
sqlplus /as sysdba
create bigfile tablespace DBFS_NEW datafile size 8G autoextend on next 1G maxsize 70G;
grant dba to dbfs_user;
alter user dbfs_user default role all;
exit

+++ REORGANIZE DBFS FILESYSTEM FS1 IN TABLESPACE DBFS_TS INTO A NEW TABLESPACE DBFS_NEW, 
+++ USING A TEMPORARY FILESYSTEM NAMED TMP_FS, WHERE ALL FILESYSTEMS BELONG TO DATABASE USER DBFS_USER
cd $ORACLE_HOME/rdbms/admin
sqlplus dbfs_user
@dbfs_create_filesystem DBFS_NEW TMP_FS
exec dbms_dbfs_sfs.reorganizefs('FS1','TMP_FS');
@dbfs_drop_filesystem TMP_FS
purge user_recyclebin;
exit

sqlplus / aa sysdba 
revoke dba from dbfs_user;
select count(*) from dba_extents where tablespace_name='DBFS_TS'; 
select count(*) from dba_extents where tablespace_name='DBFS_NEW'; 
-- DROP TABLESPACE HAVING ZERO EXTENTS
-- BE CAREFUL IN CASE USER AND DBFS ARE USING SAME TABLESPACE
Example:
create user dbfs_user identified by **** default tablespace dbfs_ts quota unlimited on dbfs_ts;
@$ORACLE_HOME/rdbms/admin/dbfs_create_filesystem.sql dbfs_ts FS1
TRUE CONFESSION:

I created an imperfect plan at first that might have saved me from a major catastrophe.

Create DBFS_TMP in a separate Disk Group since I was concern existing may not have enough storage.
Reorg from DBFS_TS to DBFS_TMP (bad idea to name tablespace as DBFS_TMP as LOB Segments migrated here).
Reorg from DBFS_TMP back to DBFS_TS.
Drop tablespace DBFS_TMP.

There’s 29G difference between old and new. How much if this space will be reclaimable due to HWM in data file?

Performing reorg twice is really not an option in prod.

RESULTS:
SEGMENT_NAME                   TABLESPACE_NAME                        MB    EXTENTS

Multiplex Redo Log

Wed, 2018-05-02 23:14

When db_create_online_log_dest_1 is defined, REDO log is not multiplexed which is good for creating STANDBY REDO.

REDO log is created at db_create_online_log_dest_1 ONLY.

However, when creating ONLINE REDO, db_create_online_log_dest_1 should NOT be defined to be multiplexed.

REDO logs are created at db_create_file_dest and db_recovery_file_dest.

Who’s Gathering DB Stats?

Thu, 2018-04-26 22:20
There was an incident where statistics were being gathered during prime operating hours causing performance issues.
One DBA already verified GATHER_STATS_JOB has already been configured to not run during critical hours.
Speculation is stats are being gathered manually and how to prove this?

AUTO JOB has OPERATION : gather_database_stats (auto).
MANUAL JOB is not being run by scheduler either; otherwise, there would be JOB_NAME.

Half of the mystery is solve, but where is gather_table_stats running from?

Framework To Run SQL For All Active DB Instances

Sat, 2018-04-14 06:52

Requirement is to configure hugepages for multiple RAC database instances.

pmon processes

grid     13296     1  0 09:39 ?        00:00:00 mdb_pmon_-MGMTDB
oracle   13849     1  0 09:40 ?        00:00:00 ora_pmon_DEV1
oracle   13851     1  0 09:40 ?        00:00:00 ora_pmon_QA1
oracle   13854     1  0 09:40 ?        00:00:00 ora_pmon_PERF1
oracle   13855     1  0 09:40 ?        00:00:00 ora_pmon_TEST1
oracle   14998     1  0 09:40 ?        00:00:00 ora_pmon_INT1

Create parameter.sh which will run parameter.sql.
You might be thinking, WTH is this person thinking!
I wanted SQL script to be reusable.

Run parameter.sql

Oracle Different Levels of Hell

Did not know there exists many levels of hell and Oracle certainly has them.

Would it be bad if someone is searching for hell and this blog is listed as top 10? :=(

Here’s the effort one needs to go through to determine what patch to apply for Goldengate software (binary) as part of quarterly Critical Patch Updates.

Hint: Goldengate does not participate in quarterly patch updates.

Find the latest patch available and patch using Opatch or install newer database compatible version using runInstaller.

Oracle GoldenGate — Oracle RDBMS Server Recommended Patches (Doc ID 1557031.1)
Latest RDBMS version Oracle Server 12.1.0.2

Let’s create a new doc for new version but don’t provide reference to it. Make the user find it.

Good But Not Good Enough Coding Practice

Sat, 2018-03-17 13:36

Good: Alert from from localhost but what script is this? If there was only 1 cron entry and intuitive, then I would not be blogging about it.

ALERT … Goldengate process “EXTRACT(PU)” has a lag of 02 hour 22 min on localhost

Better: Alert is from localhost for monitoring_gg.sh

monitoring_gg.sh ALERT … Goldengate process “EXTRACT(PU)” has a lag of 00 hour 00 min on localhost

That is all.

 

Inconsistencies – Are they good or bad?

Fri, 2018-03-09 07:40

Different companies will have different implementations of the same, e.g. backup, naming convention, to name a few.

However, should there be different implementations of the same in the company itself?

There are pros and cons to everything and there are no wrongs or rights, just objectives and requirements.

Example: if you wants to have the same experience with coffee no matter where, you goes to Starbucks.

Don’t let it frustrate you. Think of it as freedom and the opportunity to do thing the way you want to.

Is the glass half empty or half full? For me, it’s half empty because I can fill it up with what I want.
