Oracle Database Appliance – Installing Patch Bundle 2.2

On 17 April 2012 ODA patch bundle was released, which includes an Linux kernel upgrade (2.6.18- to 2.6.32-300.11.1.el5uek – Unbreakable Enterprise Kernel), Oracle Grid Infrastructure patchset and Oracle RDBMS patchset
Oracle made the installation of various parts of the patch bundle a lot more flexible. Now you can install the infrastructure (OS, firmware, OAK, etc.), GI and RDBMS parts independently from each other. You can even choose to just install the Oracle RDBMS software without upgrading the existing databases and keep them running on the current patchset. This way you can just install the “infra” part without upgrading the rest. Unfortunately you have to upgrade to GI patchset directly after upgrading the “infra” part if you are using ACFS, because ACFS in GI doesn’t work with the new Linux kernel.

Patch installation – part 1 (infra)

As with the previous ODA patch bundles, the installation of patch bundle 2.2 isn’t rolling and you will have downtime. The first part of the installation (infra) does a shutdown of the complete CRS stack (cluster) and will reboot both nodes at the end (at the same time). Depending on how many databases are running on your ODA, it will take 45 – 60 minutes before everything is running again.

Patch installation – part 2 (GI & RDBMS)

Especially if you are using ACFS (/cloudfs filesystem) you will have to install the Grid Infrastructure (GI) patchset as soon as possible. Installation of the GI patchset isn’t rolling, so again the complete CRS stack (cluster) will be shutdown. I have chosen to install the GI patchset and RDBMS patchset (software only) in one “oakcli update -patch –gi –database” run and it took around 45 minutes to complete (the cluster resources like databases aren’t available during this period).

Known issues

There are some “know issues” that come with this patch bundle. The most annoying ones I will sum down here:

  • The privileges on the “oracle” executable in the old ( home become incorrect after installing this patch bundle. So you have to fix them as noted in the patch readme.
  • With the installation of the patch bundle you can choose to let all or a selection of databases be upgraded to However there is a bug which prevents databases that have capitalized database names to be upgraded automatically.

Problems I ran into

Although the installation of ODA patch bundle went without visible problems, and it fixed a problem with a shared disk (state details for a disk: PredictiveFail), it introduced a new and I think a much bigger problem with the availability of our RAC databases. Whenever I reboot one of the ODA nodes, the RAC instances on the remaining node crash with an ORA-07445 (generated by the LMD0 daemon – Global Enqueue Service Daemon), see the error below. I have an Service Request opened for this and I will update this post whenever the problem is solved.

SKGXP: ospid 16245: network interface with IP address no longer running (check cable)
Exception [type: SIGSEGV, Invalid permissions for mapped object] [ADDR:0x7FEA51FBB592] [PC:0x7FEA548AA5E7, skgxp_local_status_change()+191] [flags: 0x0, count: 1]
Errors in file /u01/app/oracle/diag/rdbms/tstdb1/tstdb11/trace/tstdb11_lmd0_16245.trc  (incident=121697):

Problem solved!

Finally the problem with the crashing RAC instance (the surviving one) has been solved. You have to upgrade your databases (RDBMS) to or if you need to be running on you will have to apply patch 12628521SKGXP V3.4 – CUMULATIVE FIXES PATCH 6.1 (For description of the bug fixed see MOS note 11711682.8).

The problem is being described as an generic problem, but the problem doesn’t occur on ODA so it has be some combination of either the new GI ( that comes with ODA or the kernel/OS upgrade. I did ask Oracle about this, but they didn’t know (wanted to look further into this).

    Marcel, wondering if you got a resolution for your ORA-07445 problem following ODA 2.2 patch?

      Hi Martin,
      Oracle support has raised a new bug with their development team. I will keep you posted/update the post whenever I have new information.
      I have checked to make sure the issue wasn’t already there with ODA, but rebooting one of the nodes using this version will not
      crash the surviving RAC instance.

        Still no solution for the problem. I’ve escalated the SR so I hope they will get the problem fixed soon.

        Hi Martin,

        Finally the problem with the crashing RAC instances has been solved. The bug is registered under 14097156 (my bug) and 11711682 (existing bug). The solution is to apply patch “12628521 – SKGXP V3.4 – CUMULATIVE FIXES PATH 6.1”. After installing this patch the surviving RAC nodes keeps running. I did ask which combination (GI and RDBMS or new OS and RDBMS triggered this error (because the problem doesn’t occur on ODA but they don’t know.

        By the way the bug should be fixed in either, so if you can upgrade your databases to you should not run in this problem either.
