OIC - Get object from OCI object storage using OIC | Oracle Integration Cloud

Usecase: Here, we will create an object storage rest connection and using that connection, we will create an app driven integration, configure rest call to object storage and get the file from object storage.

Implementation Steps:

Step1: Create Rest connection.

Oracle home >> Integrations >> Connections >> Create >> Rest 

Provide rest API base URL


Select Securtiy as OCI Signature version 1


Provide Tenancy OCID, user OCID, private ley and fingerprint.


Test and save.

Step2: Create an app driven integration 

Integration flow:


Configure Rest input as object name and output as Binary




Call the rest connection to get the file or object from object storage

URI: /n/{namespaceName}/b/{bucketName}/o/{objectName}
Verb: GET
Configure Request Payload as Binary Format




Map the bucket name, object name and namespace.


Map the object storage response file reference to rest response.


Test


How to create a OCI object storage bucket, how to get Tenancy OCID, User OCID, API private RSA key and finger print and Namespace, everything mentioned in the previous blog. Pleae check below link.

OIC How to use OCI Object storage from the Oracle Integration Cloud | Put a file to OCI Object storage from Oracle Integration Cloud

UseCase: Here, we will create a OCI object storage bucket. From OIC, read a file and put that file to bucket using Rest connection.

Step 1 : Create a bucket in OCI object storage

In the Oracle console >> Storage >> object storage & Archive storage >> select the required compartment >> create bucket






Step 2 : Create a Object storage Rest connection

To create a Rest connection , we need to collect the following information:

Connection type : REST API Base URL

Connection URL : https://objectstorage.<region>.oraclecloud.com

My case, region is: us-ashburn-1

Securtity: OCI Signature Version 1

Tenancy OCID and Object storage Namespace: get the Tenancy OCID from the OCI console on the Tenancy Details page.

Search Tenancy in the search box


Or from profile >> Tennacy


Here we also got the Object storage namespace.

User OCID : get the user's OCID in the console on the User details page.

Profile >> User Settings




Private Key & FingerPrint: 

Profile >> User settings >> API Keys >> Add API Key >> download private key >> add >> note the fingerprint.






Oracle home >> Integrations >> Connections >> Create >> Rest 




Test and save.

Step 3:  Create the Integration

Integration flow:


Read the file 





Call the rest connection to put the file to object storage

URI: /n/{namespaceName}/b/{bucketName}/o/{objectName}
Verb: PUT
Configure Request Payload as Binary Format.




Map the namespace, bucket name, object name and fileReference to stream reference.

Save, Add Tracking and activate and test

See the below file uploaded to object storage bucket.



Note: Private key downloaded from the Oracle Cloud Infrastructure Console are in PKCS8 format. The OCI Signature version 1 security policy available with the Rest adapter only supports reading of the private key in RSA format(PKCS1) format.

If you receive the following error, you must convert the private key from PKCS8 to RSA(PKC1) format:

oracle.cloud.connector.impl.rest.security.signature.signatureException: java.lang.ClassCastException: org.bouncycastle.asn1.pkcs.PrivateKeyInfo can not be cast to org.bouncycastle.openssl.PEMKeyPair.

Convert the private key with the following command:

openssl rsa -in private_key_in_pkcs8_format.pem -out new_converted_file.pem

We can also convert it using online availavle site like below:

https://8gwifi.org/pemconvert.jsp

OIC Tracing | How to enable and use OIC Tracing | Oracle Integration Cloud

Why we need tracing: 

  • When Tracing is enabled, OIC integration prints detailed information before and after each action / activity that is executed. It also prints the message / payload of needed. 
  • We should make sure that it is enabled only for debugging purposes and turned off before going into production.
  • When tracing is enabled, integration activity can be viewed in Activity Stream.
Types of Tracing:
  1. Integration Level : If your requirement is to enable the tracing for one or more integrations and disable tracing for the rest of the integrations, you can ise Integration level tracing.
  2. Global Tracing On : It will turn tracing on for all activated flows and we can't enbale/disable it at individual level on the integration page.
  3. Global Tracing Off :  It will turn tracing off for all activated flows and we can't further enbale/disable it at individual level on the integration page.

How to change the level of Tracing:

Oracle home >> Settings >> Integrations >> Tracing





If we choose the Integration level tracing, we can enbale or disable the tracing at individual integration level following below steps:

Go To Integrations Page >> select actions >> Tracing >> Enable Tracing & Include Payload >> Save

OIC to ERP : Move custom report | download custom report based on ess job id and then move to desired folder

Usecase: Here, we will create a sub integration which will take a request id and check if ESS job status, if its succceeded, it will download the report and move the file to desired mail dl or sftp directory.

HighLevel steps:

  • Main flow (where import and child process runs) call to callback integration
  • Archive the success file
  • Execute the execution accounting report based on child request id for support help.
  • Call ESS job which internally calls the BI report to execute the SQL query to get the callback report
  • Call a Sub Integration like MoveCTRLReport and feed the ESS job process id
    • Here, check the ESS job status using getESSJobStatus(Interesting fact is that we are looping max 55 times to check if the ESS process completes )
    • If ESS process gets completed,
      • Download the control report using downloadESSJobExecutionDetails operation
      • Write the control report in stage
      • Unzip the report
      • Read the text report
      • Move the report to FTP location

Request payload:

{

"RequestId":"",

"directoryAdapter":"",

"sourceFileName":"",

"targetDirectory":""

}

Implementation logic steps:

  1. Configure rest request with post verb. Request json payload spacified above.
  2. Assign looping variables like
    1. LoopCounter = -45.0
    2. ESS_Status = ""
    3. MaxLoopCount = 9
  3. Take a while loop with condition $Loopcounter < $MaxLoopCount and $ESS_Status != "SUCCEEDED"
    1. Call Erp cloud adapter - operation: getESSJobStatus and service : erpIntegrationService and map request Id.
    2. Wait 59 sec
    3. Assign status like
      1. LoopCounter = Loopcounter +1
      2. ESS_Status = result of the getESSJobStatus
  4. Take a switch and check if ESS_Status = SUCCEEDED 
    1. If yes,
      1. Call erp cloud adapter and download control report using service: erpIntegrationService and operation: downloadESSJobExecutionDetails. And map request id
      2. Write control reports to stage location using sourceFileName, temp stage location and using opaque schema and map the content to opaque element.
      3. Unzip the zipped contents using stage
      4. Read text control report using stage and xsd opaque file. Specifying file name as unzipcontrolreport/properties[filetype='text']/filename
      5. Call another sub integration like OIC_File_Handler to move the control report to desired sftp or s3 folder. Or send a mail attaching the report.
    2. If no, throw new fault with code, reason, details.
