What convention to use for PDB?

Filed under: 12c,CDB,oracle — mdinh @ 4:55 pm

I don’t know but best to have one.

With multi-tenant database, I would use OMF to keep it simple and to avoid having to remember about FILE_NAME_CONVERT.

When creating PDB, there may be specification for ADMIN USER as show below:

CREATE PLUGGABLE DATABASE april ADMIN USER april_admin IDENTIFIED BY oracle;

Here are some examples I have come across (Names and Blogs are not provided to protect the innocents):

create pluggable database PDB1 admin user pdb1_admin 
CREATE PLUGGABLE DATABASE TESTPDB ADMIN USER TESTADMIN
CREATE PLUGGABLE DATABASE devpdb2 ADMIN USER pdb2dba
CREATE PLUGGABLE DATABASE mypdb ADMIN USER pdbadmin
CREATE PLUGGABLE DATABASE pdb3 ADMIN USER pdb_admadmin user App_Admin

It’s no big deal, right? It’s always possible to dig for it.

Just playing around.

Losing /u01

Filed under: 11g,ASM,oracle — mdinh @ 3:54 pm

There was an incident where /u01 was lost.

This means having to reinstall and patch software again.

When installing grid and I encountered:

CRS is already configured on this node for crshome=/u01/app/oracle/product/11.2.0/grid

Ah Crap! This is me being melodramatic.

The system was using Oracle Restart, it needs to be removed.

# /u01/app/oracle/product/11.2.0/grid/crs/install/roothas.pl -deconfig -force -verbose  

In hindsight, it would have been much easier to delete from /etc/oracle.

Guess what? ASM will need to be recreated and there’s a post for that.

ReCreate ASM Disks

Filed under: 11g,ASM,oracle — mdinh @ 1:33 pm

The following ASM disks were created which does not follow convention:
ASM_REDO01_006, ASM_REDO01_007, ASM_REDO01_008, ASM_REDO01_009, and ASM_REDO01_010

It should be:
ASM_REDO01_001, ASM_REDO01_002, ASM_REDO01_003, ASM_REDO01_004, and ASM_REDO01_005

Hence, we will need to recreate them. Here’s the process for me to remember.

conn / as sysasm
drop diskgroup DATA01;
drop diskgroup REDO01;

GoldenGate 12.2 Object Exclude

Filed under: 12c,GoldenGate — mdinh @ 6:06 pm

1.8 Details of Support for Objects and Operations in Oracle DDL

The following tables are excluded by default.

  "*.AQ$*", // advanced queues
  "*.DR$*$*", // oracle text
  "*.M*_*$$", // Spatial index
  "*.MLOG$*", // materialized views
  "*.OGGQT$*",
  "*.OGG$*", // AQ OGG queue table
  "*.ET$*", // Data Pump external tables
  "*.RUPD$*", // materialized views
  "*.SYS_C*", // constraints
  "*.MDR*_*$", // Spatial Sequence and Table
  "*.SYS_IMPORT_TABLE*",
  "*.CMP*$*", // space management, rdbms >= 12.1
  "*.DBMS_TABCOMP_TEMP_*", // space management, rdbms < 12.1
  "*.MDXT_*$*" // Spatial extended statistics tables

If you specify JOB_NAME for datapump, then you may have to manually add the exclusion.

Next, during migration from 10g to 12c with Goldengate, extract was failing with

2016-06-20 01:00:16  ERROR   OGG-00665  Oracle GoldenGate Capture for Oracle, e_db10g.prm:  OCI Error getting OCI_ATTR_NAME for UDT SYS.ANYDATA (status = 24328-ORA-24328: illegal attribute value), SQL.
2016-06-20 01:00:17  ERROR   OGG-01668  Oracle GoldenGate Capture for Oracle, e_db10g.prm:  PROCESS ABENDING.

The following exclusion was added to the extract.

SCHEDULER$_JOB_ARG

It might be better to add “*.SCHEDULER$*”?

GoldenGate 12.2 TROUBLESHOOTING USING GETENV

Filed under: 12c,GoldenGate — mdinh @ 2:14 am

I was faced with a very strange situation.

When using SETENV (ORACLE_SID = db01), replicat ABEND with  OGG-00664  OCI Error beginning session (status = 1034-ORA-01034: ORACLE not available

When using SETENV (ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/dbhome_1), replicat starts without any issues.

I know what you are thinking, why not set both ORACLE_SID and ORACLE_HOME and you are correct since this is best practices.

The client already knows this and wanted to troubleshoot why it was failing?

Any ideas? I scoured the internet and MOS and finally found that using get_env was the key to troubleshooting.

Tried tracing the replicat and did not work since replicat abended.

NOTE:  Environment variables are all set correctly from the OS.

BAD:

REPLICAT R_2D2
SETENV (ORACLE_SID = db01)

getenv (ORACLE_HOME)
ORACLE_HOME = /u01/app/oracle/product/11.2.0.3/dbhome_1

getenv (ORACLE_SID)
ORACLE_SID = b01
USERIDALIAS ggadmin

2016-07-21 18:33:46 ERROR OGG-00664 OCI Error beginning session (status = 1034-ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory).

GOOD:

REPLICAT R_2D2

SETENV (ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/dbhome_1)

getenv (ORACLE_HOME)
ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1

getenv (ORACLE_SID)
ORACLE_SID = db01
USERIDALIAS ggadmin

Notice, there are 2 different ORACLE_HOMEs being used.

Bad one is ORACLE_HOME = /u01/app/oracle/product/11.2.0.3/dbhome_1 since the HOME does not exists.

Wait a minute, how is it possible the HOME does not exists and where did Goldengate get this information ???

Let’s find the installation log.

/u01/app/oraInventory/logs> grep "MANAGER_PORT" installActions2016*.log|uniq

INFO: Setting variable 'DATABASE_HOME' to '/u01/app/oracle/product/11.2.0.3/dbhome_1'. Received the value from the command line.
INFO: This variable DATABASE_HOME is not added to the global context map

There it is, Goldengate is using ORACLE_HOME defined from the installation.

DATABASE_LOCATION is not required, so why set it?

Admittedly, I have have been setting DATABASE_LOCATION but will not be doing so any more.

#-------------------------------------------------------------------------------
# Specify the location of the Oracle Database.
# Required only if START_MANAGER is true.
#-------------------------------------------------------------------------------
DATABASE_LOCATION=

Lastly, I have not attempted to reproduce the error. Too lazy. May be you can help?

No more triggers!

Create 12c CDB using dbca or sqlplus ???

Filed under: 12c,CDB,oracle — mdinh @ 10:27 pm

How do you typically create database, using dbca or sqlplus?

I am still surprised with all the bloatware added for creating database using dbca.

Also, is there a reason to prefix PDB with pdb?

GoldenGate and Networking

Filed under: GoldenGate,linux — mdinh @ 4:16 am

I have never delved into networking for GoldenGate since things just work. Due to security tightening, telnet is no longer available to verify opened port.

What’s to follow is a demo for ports being listened by GoldenGate when manager started and ports listened and when PUMP Extract is started as part using DYNAMICPORTLIST.

Also, how to test opened port using (nc – arbitrary TCP and UDP connections and listens)

Both source and target are running on the same host; however, the same principles still apply.

HAWK (source): PORT 7901 and DYNAMICPORTLIST 15100-15120

THOR (target):   PORT 7801 and DYNAMICPORTLIST 15200-15220
