How to clone Oracle Software fast and easy

This is the approach I’m usually taking to clone the Oracle Software from one server to another.

[oracle@PROD product]$ zip -r 11204_clone.zip 11.2.0.4/
 adding: 11.2.0.4/ (stored 0%)
 adding: 11.2.0.4/owm/ (stored 0%)
 adding: 11.2.0.4/owm/jlib/ (stored 0%)
 adding: 11.2.0.4/owm/jlib/owm-images.jar (deflated 2%)

..........

  adding: 11.2.0.4/bin/okinit0 (stored 0%)  adding: 11.2.0.4/bin/okinit0 (stored 0%)  adding: 11.2.0.4/bin/nmozip warning: Permission denied zip warning: could not open for reading: 11.2.0.4/bin/nmo  adding: 11.2.0.4/bin/agtctlO (stored 0%)  adding: 11.2.0.4/bin/nmcbufp (deflated 65%)  adding: 11.2.0.4/bin/impdpO (stored 0%)

...........

adding: 11.2.0.4/odbc/mesg/oraodbcus.msb (deflated 68%)
 adding: 11.2.0.4/odbc/mesg/oraodbcja.msb (deflated 68%)

zip warning: Not all files were readable
 files/entries read: 40416 (4.9G bytes) skipped: 3 (144K bytes)
[oracle@PROD product]$ exit

Now send the zip file to the target server:

[oracle@PROD software]$ scp /u01/app/oracle/product/11204_clone.zip DEV:/tmp

Create the same oracle path for the ORACLE_HOME

mkdir -p /u01/app/oracle/product

Unzip the archive to previously created folder:

unzip 11204_clone.zip -d /u01/app/oracle/product/

Navigate to this clone folder within the unzipped oracle software:

cd /u01/app/oracle/product/11.2.0.4/clone/bin

[oracle@DEV bin]$ pwd
/u01/app/oracle/product/11.2.0.4/clone/bin
[oracle@DEV bin]$ perl clone.pl ORACLE_BASE=/u01/app/oracle ORACLE_HOME=/u01/app/oracle/product/11.2.0.4 ORACLE_HOME_NAME=OH_11204

ORA-16631: operation requires shutdown of database or instance

On short, after upgrading one of my databases from 11203 to 11204, I’ve noticed that the standby database was in a DISABLED state:

 

DGMGRL> show configuration

Configuration - DG_CONFIG

Protection Mode: MaxPerformance
 Databases:
DB_PRI- Primary database
 DB_STANDBY - Physical standby database (disabled)

Fast-Start Failover: DISABLED

Configuration Status:
SUCCESS

 

I tried to set it to ENABLED state like this:

DGMGRL> enable database 'DB_STANDBY'
Error: ORA-16631: operation requires shutdown of database or instance ""

Failed.
DGMGRL> exit

To fix this, I’ve found the following document on Metalink:

Ora-16631: Operation Requires Shutdown Of Database Or Instance “” On Physical Standby (Doc ID 1258074.1)

DGMGRL> show configuration

Configuration - DG_CONFIG

ORA-01450 maximum key length (3118) exceeded

All of a sudden, deploying a new version of the apps, I got this error. The fix is simple. The error is related to the block size of the tablespace where you want to deploy your object. In my case it was about the creation of an index an the key was exceeding the size of the default block size of the default tablespace. All I had to do is to enable the 16K block size and to create a new tablespace using the 16k block size.

SQL> ALTER TABLE "USER"."TABLE1" ADD CONSTRAINT "CONSTR_UK" UNIQUE ("COL") USING INDEX TABLESPACE "TBS_DEFAULT";
ALTER TABLE "USER"."TABLE1" ADD CONSTRAINT "CONSTR_UK" UNIQUE ("COL") USING INDEX TABLESPACE "TBS_DEFAULT"

DIA-48322: Relation [INCIDENT] of ADR V[2] incompatible with V[2] tool

I got this issue while using ADRCI tool to maintain the logs. This is how I fixed it:

[oracle@dbserver ~]$ adrci

Find the Oracle session that’s using a lot of resources on a Linux system

To find that, I did the following:

[oracle@dbserver marius]$ ps aux | sort -nrk 3,3 | head -n 10
oracle 28986 75.8 1.6 10739264 1602896 ? Rs Jan24 137897:06 ora_q002_DBINST

oracle 8342 13.3 5.9 10736636 5858864 ? Rs May28 319:50 oracleDBINST (LOCAL=NO)

 

And then on the sqlplus:

SYS @ DBINST > select s.sid, s.serial#, s.username,
 to_char(s.logon_time,'DD-MON HH24:MI:SS') logon_time,
 p.pid oraclepid, p.spid "ServerPID", s.process "ClientPID",

where p.spid=nvl('&unix_process',' ')
and s.paddr=p.addr
order by s.sid 2 3 4 5 6 7 8 9 
 10 ;
Enter value for unix_process: 28986

So it seems that the STREAMS are very busy 🙂
