About the Patch Tool

Oracle WebCenter on Marketplace in Oracle Cloud Infrastructure (OCI) provides a patching utility tool to download and apply patches for the WebCenter instances. 

You can apply a patch on the WebCenter compute instances using this patch tool.

The patch tool should be executed only on WebCenter Weblogic Admin server instance which has a hostname ending with '-wls-1'.

Note: This patching mechanism involves downtime.

See the following sections:

Patch Management Using the Patch Tool

Patch Management Using the Patch Tool

Use the patch tool utility in Oracle WebCenter on Marketplace on OCI to list, download, and apply patches. 

List Patch

  1. Connect to the bastion instance as the opc user.

    ssh -i path_to_private_key opc@bastion_public_ip

  2. Connect to the weblogic admin server compute instance which has a name ending with 'wls-1'.

    ssh -i path_to_private_key opc@compute_wls-1_private_ip

  3. Change to 'Oracle' user.

    [opc@**-wls-1 ~]$ sudo su - oracle

  4. Go to the patch tool path.

    [oracle@**-wls-1 ~]$ cd /u01/scripts/patch/

  5. List the patches.

    [oracle@**-wls-1 patch]$ sh patch_tool.sh --list_available_patches
