About Oracle WebLogic Server for Oracle Cloud Infrastructure Versions and Retirement Policy

Oracle WebLogic Server for Oracle Cloud Infrastructure versions adopt the standard Oracle multiple digits system for version numbering.

A version number for Oracle WebLogic Server for Oracle Cloud Infrastructure contains six decimal places in the form:

WLS n.n.n.n.yymmdd.n

For example:

WLS 12.2.1.3.190716.01
WLS 10.3.6.0.190716.01

The first 4 decimal places together describe the base version of a WebLogic Server release, such as:

12.2.1.3 for Oracle WebLogic Server 12c Release 2

10.3.6.0 for Oracle WebLogic Server 11g Release 1

The 5th decimal place is a quarterly patch set release date. For example, 190716 is the July 2019 patch set.

For patch set update (PSU) naming purposes, releases in a quarterly patch set for Oracle WebLogic Server for Oracle Cloud Infrastructure are named uniquely by the 6th decimal place. The first release is 01. The number is incremented by one for every patch or every update of that patch set, including one-off patches and updates to the VM image, the WebLogic scripts placed on the VM images, the Terraform scripts, and the Resource Manager schema.

An Oracle WebLogic Server for Oracle Cloud Infrastructure PSU is created from the Critical Patch Updates (CPUs) of several products, namely, Oracle WebLogic Server, Oracle JDeveloper, Oracle Java Development Kit, Oracle Platform Security Services and Oracle Web Services Manager. While the Oracle WebLogic Server for Oracle Cloud Infrastructure quarterly patch set release date (yymmdd) is mainly derived from a WebLogic Server PSU, the latest PSUs of all those products are included. See Patches Included in Oracle WebLogic Server for Oracle Cloud Infrastructure.

Oracle WebLogic Server for Oracle Cloud Infrastructure PSUs do not retire based on any fixed time range. Instead, for each WebLogic Server release (12c or 11g), only the last two patch sets (identified by yymmdd) are retained in a quarter.

For example, suppose at the end of December 2019 there are two July PSUs and two October PSUs for WebLogic Server release 12.2.1.3:

12.2.1.3.190716.01
12.2.1.3.190716.02
12.2.1.3.191016.01
12.2.1.3.191016.02

When the 2020 January PSU is released (say, 12.2.1.3.200116.01), the July PSUs are retired and only the PSUs for October 2019 and January 2020 are retained:

12.2.1.3.191016.01
12.2.1.3.191016.02
12.2.1.3.200116.01

Similarly, if WebLogic Server release 10.3.6.0 has the same number of PSUs, the following PSUs are retained when the January 2020 PSU is released:

10.3.6.0.191016.01
10.3.6.0.191016.02
10.3.6.0.200116.01

Note the following about all retained Oracle WebLogic Server for Oracle Cloud Infrastructure versions and images:

  • The Oracle WebLogic Server for Oracle Cloud Infrastructure image of a version is retained as-is, including the WebLogic Server binaries, the VM image contents, and any bugs that were inherent to the WebLogic scripts on the VM.
  • Bugs fixed in a later version are not back ported into an earlier version.
  • A version may be pulled without notice if there is a very serious security or functional issue.
