You can identify a Zero Downtime (ZDT) patch by the value of the patch uptime option in the patch metadata.

After you download a patch, open up patchdeploy.xml in the PATCH_HOME/etc/config directory, where PATCH_HOME is the location of the patch directory that contains the patch.

If the value of patch-uptime-option is FMW_ROLLING_ORACLE_HOME, as shown in the following example:

<patch-uptime-option>FMW_ROLLING_ORACLE_HOME<patch-uptime-option>

OR the value is FMW_ROLLING_SESSION:

<patch-uptime-option>FMW_ROLLING_SESSION<patch-uptime-option>

Then, the patch is suitable for ZDT patching.

If FMW_ROLLING_ORACLE_HOME or FMW_ROLLING_SESSION does not appear in the patch metadata, then you know that the patch is not suitable for ZDT patching, and as a result, not compatible with a ZDT patch plan. The value of the patch uptime option will help you select the appropriate patch plan for applying the patch
