Create oracle ASM DISK on linux

  

I created 3 shared disks in my VM Box

DISK1 -3G

DISK2 -20G

DISK3 -10G


List Disk

 

[root@oraclelab1 dev]# ll sd*

brw-rw---- 1 root disk 8,   0 Aug  6 10:28 sda

brw-rw---- 1 root disk 8,   1 Aug  6 10:28 sda1

brw-rw---- 1 root disk 8,   2 Aug  6 10:28 sda2

brw-rw---- 1 root disk 8,  16 Aug  6 10:47 sdb

brw-rw---- 1 root disk 8,  17 Aug  6 10:47 sdb1

 

Oracle ASM Configuration

Executing Root Configuration Scripts

[root@oraclelab1 ~]# /u01/app/oracle/product/19.0.0.0/dbhome_1/root.sh

Performing root user operation.

 

The following environment variables are set as:

    ORACLE_OWNER= oracle

    ORACLE_HOME=  /u01/app/oracle/product/19.0.0.0/dbhome_1

 

Enter the full pathname of the local bin directory: [/usr/local/bin]:

The contents of "dbhome" have not changed. No need to overwrite.

The contents of "oraenv" have not changed. No need to overwrite.

The contents of "coraenv" have not changed. No need to overwrite.

 

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root script.

Now product-specific root actions will be performed.

Oracle Trace File Analyzer (TFA - Standalone Mode) is available at :

    /u01/app/oracle/product/19.0.0.0/dbhome_1/bin/tfactl

 

Note :

1. tfactl will use TFA Service if that service is running and user has been granted access

2. tfactl will configure TFA Standalone Mode only if user has no access to TFA Service or TFA is not installed

 

[root@oraclelab1 ~]#

 

Finishing Installation



Creating ASM Disk Group:

 

I am using (ASM Configuration assist) asmca and creating two disk group

 

Disk Group name :DATA,RECO

 

[oracle@oraclelab1 ~]$ cd /u01/app/19.0.0.0/grid/bin/

[oracle@oraclelab1 bin]$ ls -ltr asmca

-rwxr-x--- 1 root oinstall 7912 Aug  7 13:41 asmca

[oracle@oraclelab1 bin]$ ./asmca



Configuring Data RECO disk group 

 

Enter the Disk group name

Disk group Name: DATA



Disk group created

Database Creation


[oracle@oraclelab1 bin]$ pwd

How to troubleshoot long running concurrent request in R12.2

By -
Normally we are getting concurrent program running longer and concurrent request not picking jobs, etc. those are very frequent issue we expected from development team. Collect below basis level of information to development team 1 Oracle seeded program/Custom program? 2 How much time it used earlier? 3 Is there any recent code change done in concurrent program? 4 Is this program fetching higher data compare to last run? 5 Does this job running any specific time/ It can be run any time? 6 Does this job fetching data using DB link? 7 Does the problem happen on both the test and production instance? Once asked above questions to development team in meanwhile we need to start basic sanity check in our environment. 1 Verify the status of the concurrent program select REQUEST_ID,phase_code,status_code,ORACLE_SESSION_ID from apps.fnd_concurrent_requests where request_id=’1234567’; 2 Find which concurrent manger ran a specific concurrent request select b.USER_CONCURR
