psm jcs precheck-patch

Use this command before actually patching the Oracle Java Cloud Service instance to identify potential issues that might prevent the specified patch from completing successfully.

Patching precheck reports on the following conditions:
  • Disk space shortage.

  • Database connectivity failure.

  • Server access failure.

  • Storage access failure

Prechecks do not check whether another administration task (backup, restoration, or scaling) is in progress, although these will also prevent patching.


In the following syntax, line breaks have been added for clarity. Do not include them when entering the command.

psm jcs precheck-patch -s|--service-name serviceName 
  -p|--patch-id patchId 
      [-of|-–output-format json|html|short]  
      [-wc|--wait-until-complete true|false] 


All parameters are required unless otherwise noted.

Parameter Description
-s|--service-name serviceName Name of the Oracle Java Cloud Service instance.
-p|--patch-id patchId Patch Id for the patch that requires to have a precheck done.
-of|-–output-format json|html|short (Optional) Output format of the command’s response:

Accepted values: json, html, short

The default output format is the one you specified when using the psm setup command to configure the psm CLI.

-wc|--wait-until-complete true|false

(Optional) A boolean value that, when set to true, makes the command behave synchronously; that is, it does not return until the submitted job is complete. The following message is displayed until the job is complete:
Waiting for the job to complete... (it cannot be cancelled)
Default: false


$ psm jcs precheck-patch -s Example1Instance -p Test_Patch_12. -of json 
        "message":"JCS-PATCHING-5227: Pre-Checking service for patch [Test_Patch_12.] is submitted as an asynchronous job."
Job ID : 34177

Note that this command returned a job ID. To see the status of your precheck-patch operation, use this ID with the psm jcs operation-status command:

$ psm jcs operation-status -j 34177 -of json

When you see the message:


the patch precheck is complete.
