A Real-World Oracle EBS OCI Migration: Why We Picked WebLogic UCM

 

Recently, one of my long-time customers, who has been running Oracle E-Business Suite (EBS R12.2 with Oracle 19c) on-premises for many years, started discussing a long overdue infrastructure refresh. Their existing servers had aged considerably, and continuing with the same setup no longer looked practical.

Since I had worked with them for quite some time, they reached out to discuss possible options and get my thoughts on the best way forward.

One thing was very clear from the beginning that is although they wanted to modernize the environment, they were not keen on maintaining annual support costs (ATS) or investing heavily in upfront licensing again.

After understanding their requirements, I suggested a simpler approach: use Oracle DBCS for hosting the Oracle Database and consider an Oracle WebLogic Suite UCM image for the EBS application tier. This allowed them to move to OCI without the burden of managing separate WebLogic licensing upfront.

Here is how we launched the instance from oci console :-

Login to cloud.oracle.com and click on navigation menu.

In the Search field, type "Oracle WebLogic Suite UCM Image".

Click "Launch instance", and on the top right of  screen, to launch the instance.

Choose the OS version on which the instance would be launched. Click on Launch instance

Select instance name and compartment under which the instance would be launched

If you wish to change the shape of the instance, you can do so by clicking on change shape option. And click on Next.

In the network section, provide vcn and subnet as per your environment. Ensure vcn and subnet is already created before launching the instance. and click on next.

Since our VM is associated with a private subnet and I chose the option “Automatically assign private ipv4 address” 

In the Add SSH keys region, select Choose generate a pair for me and download the keys.

In the Boot volume section, you can either accept the default volume size or change it if desired.

And Click Create to create your Compute instance.

 

Once the instance is launched, log in to the instance as the opc user via SSH and perform the following steps: Remove the oracle user by entering the following commands:

Remove the oracle user by entering the following commands:

$ sudo userdel -rf oracle $ sudo usermod --shell /bin/bash root

 

Install the Oracle E-Business Suite RPM using the following command: For Oracle Linux 8 installation, use the following yum command:

$ dnf install oracle-ebs-server-R12-preinstall.x86_64

 

Create the required soft link for the motif library:

sudo ln -s /usr/lib/libXm.so.4 /usr/lib/libXm.so.2

 

Run the following commands to perform required cleanup

$ sudo dnf history redo last $ sudo dnf remove --duplicates $ sudo dnf update

   

Use the following commands to remove the content of the

/u01 directory:

[opc@ebs_ucm u01]$ pwd /u01 [opc@ebs_ucm u01]$ ls -lrt total 0 drwxrwxr-x. 5 oracle oracle 65 May  22 10:57 zips drwxrwxr-x. 2 oracle oracle 6 May 22 10:57 logs $ sudo rm -rf

 

Now our ucm instance is ready for EBS installation or migration. The path is straightforward and same as we perform for any EBS application migration.

How to permanent change hostname in OCI for OEL 7 and later version

 

Step 1.

Update the /etc/hostname file following command.   [root@uat-database-dr rman_bkp]# hostnamectl set-hostname ccuine1126.xxx.co.in

 

 Step 2.

Edit the oci configuration file for hostnames and set the value to 2.     vi /etc/oci-hostname.conf     PRESERVE_HOSTINFO=2     save the changes.   Note:- By setting Value 2, it preserve user configured hostname across instance reboots; no custom changes to /etc/hosts and /etc/resolv.conf from the metadata service, but dhclient will still overwrite /etc/resolv.conf

  

Step 3.

Update /etc/hosts file with following

192.168.10.126 ccuine1126.xxx.co.in        ccuine1126

And save & exit.

 

Step 4.

Update FQDN in OCI Console

Login to OCI console and navigate to compute instance

Select the compute instance where the FQDN will be updated and click on Attached VNICs and click on the Edit vnic 

This open a window like below where we need to set the updated hostname.

Note: Only provide the sub domain name . Do not enter entire FQDN as it doesn’t accept it.

And click on save changes. 

Once done, bounce the instance from and it will show updated FQDN from OCI console as well.

 Check the hostname with hostname or hostnamectl command.

 

[root@ccuine1126]# hostname ccuine1126.xxx.co.in   [root@ccuine1126]# hostnamectl    Static hostname: ccuine1126.xxx.co.in          Icon name: computer-vm            Chassis: vm         Machine ID: aef0b6747ebeb75af2d053485bed            Boot ID: 3a4b979bdf3b4a3591328acc3e362     Virtualization: kvm   Operating System: Oracle Linux Server 7.9        CPE OS Name: cpe:/o:oracle:linux:7:9:server             Kernel: Linux 5.4.17-2136.304.4.1.el7uek.x86_64       Architecture: x86-64

Bucket named xxxx has pending multipart uploads. Stop all multipart uploads first.

So I received the above error while dropping the bucket in OCI object storage.

As the error reports there is files which are either being uploaded into the bucket or those files are stuck somewhere. As in our case there was no files were getting uploaded when I received the above error.

To find out what files are being uploaded run the following command from OS level. This should be run as os user from which the upload was initiated.

Command:- oci os multipart list –bucket-name <yourbucketname>

[prodtestdb@ccuine23 ~]$ oci os multipart list --bucket-name bucket-201120                                                  {

  "data": [

    {

      "bucket": "bucket-201120",

      "namespace": "bm626zu42e0a",

      "object": "online_L0_PRODTEST_149_1",

      "time-created": "2020-11-24T20:59:47.752000+00:00",

      "upload-id": "2e55d944-e192-ae09-bf4e-8289eb2dcea4"

    },

    {

      "bucket": "bucket-201120",

      "namespace": "bm626zu42e0a",

      "object": "online_L0_PRODTEST_153_1",

      "time-created": "2020-11-24T20:59:47.802000+00:00",

      "upload-id": "73d09a66-689d-558d-5570-4c8ae29fadcf"

    },

    {

      "bucket": "bucket-201120",

      "namespace": "bm626zu42e0a",

      "object": "online_L0_PRODTEST_156_1",

      "time-created": "2020-11-24T20:59:48.094000+00:00",

      "upload-id": "91cad581-82e6-09d5-caf8-a4d4d5fa029a"

    }

  ]

}

 

So as we can see the above objects are stuck and didn’t upload successfully , because of that we are unable to delete the bucket.

To remove pending upload files.

Command:- oci os multipart abort -ns <object_storage_namespace> -bn <bucket_name> --object-name <object_name> --upload-id <upload_ID>

 

 [prodtestdb@ccuine23 ~]$ oci os multipart abort --bucket-name bucket-201120 --object-name online_L0_PRODTEST_149_1  --upload-id 2e55d944-e192-ae09-bf4e-8289eb2dcea4

WARNING: Are you sure you want to permanently remove this incomplete upload? [y/N]: y

[prodtestdb@ccuine23 ~]$ oci os multipart abort --bucket-name bucket-201120 --object-name online_L0_PRODTEST_153_1  --upload-id 73d09a66-689d-558d-5570-4c8ae29fadcf

WARNING: Are you sure you want to permanently remove this incomplete upload? [y/N]: y

[prodtestdb@ccuine23 ~]$ oci os multipart abort --bucket-name bucket-201120 --object-name online_L0_PRODTEST_156_1  --upload-id 91cad581-82e6-09d5-caf8-a4d4d5fa029a

WARNING: Are you sure you want to permanently remove this incomplete upload? [y/N]: y

  

Now check again if anymore pending files are there for upload.

[prodtestdb@ccuine23 ~]$ oci os multipart list --bucket-name bucket-201120

[prodtestdb@ccuine23 ~]$

[prodtestdb@ccuine23 ~]$

 

As there is no files left to upload, we can now safely drop the bucket.

How to mount OCI object storage as a file system

 

In this topic I will show how to easily mount an object storage as a file system in any linux system.

In this case I am using a machine that is running on OEL 7

Step 1. Firstly, we will need to create a bucket in OCI. The steps of bucket creation is given in this post.

Step 2. Install s3fs-fuse rpm

[root@bastionhost opc]# yum install s3fs-fuse

.....

.....

Installed:

  s3fs-fuse.x86_64 0:1.86-2.el7

Dependency Installed:

  mailcap.noarch 0:2.1.41-2.el7

Complete!

[root@bastionhst opc]#

Step 3. Generate secret keys

Login to OCI console 

Click on User Settings

Under Resources section click on Customer Secret Keys

Click on Generate Secret key to generate secret keys

Provide a name for the key.

This will generate key , it’s important to save the key as it won’t be shown again.

The S3 credentials are created by using an access key and the secret key. The access key is displayed in the Customer Secret Keys area of the Console.

 

Step 4. Enter your credentials in a ${HOME}/.passwd-s3fs file and set owner-only permissions:

Run this from root user. 

echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > ${HOME}/.passwd-s3fs

Here for  ACCESS_KEY you can get it from Generate secret key page.

For SECRET_ACCESS_KEY , we already saved it while generating it in previous step

Example:-

echo xxxxxxxxxxxxxxxxxxx:yyyyyyyyyyyyyyyyyyyyyyy > ${HOME}/.passwd-s3fs

in this example xxxxxxxxxxxxxxxxx is access key and yyyyyyyyyyyyyyyyy is secret key.

Once password file is created assign proper permission to it 

chmod 600 ${HOME}/.passwd-s3fs

Step 5. Create a directory to mount the storage and mount the object storage

mkdir /s3bucket

To mount the object storage use the following command:-

s3fs [bucket_name] [destination directory] -o endpoint=[region] -o passwd_file=${HOME}/.passwd-s3fs -o url=https://[namespace of object storage].compat.objectstorage.[region].oraclecloud.com/ -onomultipart -o use_path_request_style

example:-

s3fs test_bucket /s3bucket -o endpoint=ap-mumbai-1 -o passwd_file=${HOME}/.passwd-s3fs -o url=https://bm626z56fa0a.compat.objectstorage.ap-mumbai-1.oraclecloud.com/  -onomultipart -o use_path_request_style

Here test_bucket is our bucket name

/s3bucket denotes the local mount point where the object storage is mounted

bm626z56fa0a – this denotes the namespace of the object storage.

Step 6. Verify the mount point

[root@s3bucket]# df -h /s3bucket/

Filesystem      Size  Used Avail Use% Mounted on

s3fs            256T     0  256T   0% /s3bucket

[root@ s3bucket]#

To mount the object storage when system reboots, add the following line in /etc/fstab file.

s3fs#test_bucket /s3bucket fuse _netdev,allow_other,use_path_request_style,passwd_file=/root/.passwd-s3fs,url=https://bm626z56fa0a.compat.objectstorage.ap-mumbai-1.oraclecloud.com 0 0

How to create object storage in OCI

In this topic I will show how to create an object storage in OCI 

In OCI there are two kind of object storage available.

• Standard Object storage : The standard object storage is used where we need access the data very fast and in a frequent manner.

• Archive Object Storage:  As the name suggests, this type of storage is used for archiving process , where the data is accessed rarely and kept for long time.   

To create an object storage in OCI

Click on Create bucket

 

Provide details for bucket creation.

 

Take a note of namespace value.

 

So the bucket is now created, we can now upload the files into bucket.

We can also upload files directly to bucket from server level using CLI . I have shared the steps in this post.

How to upload files from on premise to object storage using OCI CLI

In this topic I would explain how to upload files from on premise machine to oracle cloud using CLI. Many customers like to place their on premise backup into cloud object storage for various reasons. In this post I would share the steps of how to upload the files into OCI object storage.

Step 1

Install the CLI:-

[root@server1]## bash -c "$(curl -L https://raw.githubusercontent.com/oracle/oci-cli/master/scripts/install/install.sh)"

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

Step 2.

Setup OCI configuration:-

Before setting up OCI configuration , we would require following information such as OCI user OCID, tenancy OCID, Compartment OCID , region etc.

To find out OCI user OCID

Take a note of user OCID

To find out tenancy OCID

Take a note of Tenancy OCID

To find out compartment id

Select the compartment where the oci instance belongs to.

 [root@ccuine23 ~]# /root/bin/oci setup config

Config written to /root/.oci/config

 

    If you haven't already uploaded your API Signing public key through the

    console, follow the instructions on the page linked below in the section

    'How to upload the public key':

 

        https://docs.cloud.oracle.com/Content/API/Concepts/apisigningkey.htm#How2

 

 

Step 3.

Once configuration is done, go to the path where the public key has been created in the server.

Add compartment_id in the config file.

 [root@server1]# vi /root/.oci/config

compartment_id=ocid1.tenancy.oc1..**********************xhuxifteoynzcrkhheeja5c5vtrv7fhy5wefxq

 

Upload the file oci_api_key_public.pem into oci.

[root@server1]# cd /root/.oci/

 [root@server1]# cat oci_api_key_public.pem

-----END PUBLIC KEY-----

Login to OCI console

Under Resources select the option API Keys

Click on Add Public key option and paste the public key which was generated earlier .

Step 4. 

Testing the configuration:-

From the on premise instance run the following command to test the connectivity.

 [root@server1]# /root/bin/oci iam user api-key list --user-id ocid1.user.oc1..aaaaaaaadluyrev22yy5tbffzysx3wps6anbp7y3mkd3oqgkv24q7wycjgrq

{

  "data": [

    {

      "fingerprint": "9f:b9:49:35:01:6f:31:38:07:03:5f:c9:24:13:6a:64",

      "inactive-status": null,

      "key-id": "ocid1.tenancy.oc1..aaaaaaaaicv6vyqwreetlbdyf4fgghm75wottdro6ito5xg4mq/ocid1.user.oc1..aaaaaaaadluyrev22yy5tbffzysx3wpwerp7y3mkd3oqgkv24q7wycjgrq/9f:b9:49:35:01:6f:37:38:07:03:5f:c9:24:13:6a:64",

      "key-value": "-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAp0rjYTvNRnql87jbQCnJ\n9ARiS/rb3oCrUziSeAHaDrGwS+mNFkF+M5RJeM0GNdlLCUbLuaZDR+vZHLmGZGD8\nhyYPNW1K7dduG3SRsGKjILm75ioeHYFgi1bldPD16lc2emt0q4/OtdDqbMUlqj12\nbllYY0cSfVFTJzdnK/Fcb3YGg2UW3Pk3CDdyed+werewr/XwCHyfkZpCpQrOEvdkgoaEjF1C8dwNMcIINCcWCNSOTbxvPyma4\n2k+wZcmysR3TQBs8+5Ww5+UtcaVUbuPh9RHd1Ch6Eas6woxHxEoaHYlNDS4jL8Sn\nXQIDAQAB\n-----END PUBLIC KEY-----",

      "lifecycle-state": "ACTIVE",

      "time-created": "2020-11-16T08:49:24.642000+00:00",

      "user-id": "ocid1.user.oc1..aaaaaaaadluyrwer43wps6anbp7y3mkd3oqgkv24q7wycjgrq"

    }

  ]

}

 

From the above output it shows the connection is successful.

Step 5.

Uploading objects into OCI object store:-

Before uploading the objects  ,we need to create an object storage in OCI

Click on Create bucket

Provide details for bucket creation.

Take a note of namespace value.

Now lets upload files from on premise machine.

[root@server1 upload]$mkdir /test/bkp/upload

[root@server1 upload ]touch xyz

Use the following command to upload the objects into object storage

oci os object put -ns <object_storage_namespace> -bn <bucket_name> -–file <file_location>

 

[root@ccuine23 .oci]# oci os object put -ns bm64se5fa0a -bn test_bucket --file /test/bkp/upload/xyz

Uploaded xyz  [####################################]  100%

 

{

  "skipped-objects": [],

  "upload-failures": {},

  "uploaded-objects": {

    "xyz": {

      "etag": "699c6a97-6124-4da9-b801-01360e99a364",

      "last-modified": "Mon, 16 Nov 2020 09:21:03 GMT",

      "opc-content-md5": "1B2M2Y8AsgTpgAmY7PhCfg=="

    }

  }

}

 

Bulk Upload of all files inside a directory:-

oci os object bulk-upload -ns bm626zuufa0a -bn test_bucket --src-dir /test/bkp/upload

 

So this concludes the process of uploading files from on prem machine to OCI object storage.
