New My Oracle Support – updates and issues

This entry was posted in My Oracle Support Oracle on by

Oracle is taking seriously the confusion created with the abrupt migration to the new My Oracle Support (MOS) portal. Today there was a meeting between several VPs and other responsible and the Oracle ACE community. Thanks a lot!

We see many things are being improved and solved and the team is working hard to get the trust back from the community. We are here to help!

My top issues today (15.Dec.2025) with the new MOS are here:

Content related issues

  1. A list with “Last viewed Docs” + “Last searches” sections would very useful to find again documents. The list should include the last updated date in a column
  2. In “My Favorites” section, it is important to see the “last updated date” as a column. Old DocId may be removed. Folders/Categories were useful
  3. The “Favorites” were the base for the “Oracle Support HOT Topics” daily email, and this was where users can get information if any of our favorites was updated. This email seems not to exist anymore.
  4. Bugs are not part of the search – it is useful to know the bug exists, even if it is marked “not public”. This was the case in old MOS;
  5. Missing wget script to download patch – this was important, as usually we do not have browsers where we need the patch;
  6. SRs in “Pending Final Closure” do not appear any where (neither open, nor close). Should be in “need your attention” part. (Example SR 4-0001431240)
  7. There are still too many “Request Header Or Cookie Too Large” errors!
  8. Login timeout even when actively using the portal!
  9. Search results do not prioritize recent and most viewer content (example, search for “CPU October 2025” – it does not give KB795208 which is a top50 document)
  10. Internal links are not working (low priority)

UX related issues

  1. Choose sections to have in front page
    • My Favorites + My last viewed searches are important for me in first page
    • Archived Service Requests are not important to me in first page
  2. The Search box should be visible on every page, without need to return to the Home!
  3. Some text overflows the defined column and cannot be read (see KI35841)
  4. Instead of having two columns (left column with Title, DocID, Last Updated, Service | right with Doc text)
    • better would be two cells, top cell with content of the left column, followed by bottom cell with text
    • both cells would have 1296px width, which would give more place for tables (and the document title in top)

E-Mail related issues

  1. SR update emails do not have the “Title” of SR neither information the “Tenancy” the SR relates. As consultant I’ve about 50 CSI/Tenancies and this is important to prioritize my work
  2. SR Creation and Update emails do not have the information about the “Tenancy”.

I’m sending this information also by email to my contacts at MOS, hoping it helps prioritizing the issues.

New Oracle Support portal DocID to KB link translation 2

This entry was posted in My Oracle Support on by

Here is a table with the correspondence between the Document ID from the legacy My Oracle Support portal and correspondent KB document and link on the new portal.

Sometimes it is possible to find the new DocID by using these URLs:
https://support.oracle.com/support/?kmContentId=<oldDocID without ending .1>
or
https://support.oracle.com/epmos/faces/DocumentDisplay?id=<oldDocID>

For instance, DocID: 888.1 can be found with (note removed ending .1): https://support.oracle.com/support/?kmContentId=888

To download patches, you can use this URL: https://support.oracle.com/support/?patchId=<patchID>

These are the new links for the documents I use the most…

Update 10.12.2025: Oracle provided a similar link translation table with the Top50 Documents.

Classic My Oracle Support is gone

This entry was posted in My Oracle Support Oracle 19c on by

This morning I wanted to look for a note and to my surprise the old Metalink, then My Oracle Support portal, did not exist anymore.

All is now merged in the new “My Oracle Support” site, previously known as “My Oracle Cloud Support”.

The link to bookmark is https://support.oracle.com/support/

New DocID, now is KB

Important to notice is, The  DocID number were changed. For instance, to find the following note:
    ”How to add an Additional Listener in RAC setup (Doc ID 2456650.1)”

You need to look for the title. The document has now a new ID, starting with KB (Knowledge Base):

The links from Google are still not updated and do not work.

The solution is to search for the title in the new Oracle Support site.

Or use the MOS DocId to KB link translation I’ve compiled.

Old SRs, new SRs

The SRs from the “classic” portal are now at the end of the list as “Archived Service Requests”.

There are three headings now:

  1. These service requests need your attention
  2. Oracle is working on these service requests for you
  3. Archived Service Requests (last 2 years from old portal)

To create new SRs for On-premises, you need to search for “Oracle Database”:

Feedback

Unfortunately there is not anymore the possibility to:

  • see last searches
  • see last views documents/notes
  • favorites
  • use old DocID in the search (would be enough to keep in the text of the new note!)
  • No wget script to download patches
  • Search engine does not prioritize most viewed notes

I’ll get used to the new portal, but as everytime, changes are not easy.

Status 10.12.2025:

Recognize Oracle Client installation

This entry was posted in Oracle Oracle 23ai and tagged client on by

On my environment script I want to recognize if an ORACLE_HOME belongs to a database or is just a client installation. Oracle does the following in its Oracle 26ai client runInstaller:

...
ORACLE_SERVER_PATH="${ORACLE_HOME}/inventory/Components21/oracle.server";
ORACLE_GSM_PATH="${ORACLE_HOME}/inventory/Components21/oracle.dslm";
# Check if the directory oracle.server exists
# If it exists, then the product is db otherwise is client
if [ -d $ORACLE_SERVER_PATH ]; then
...
  ${ORACLE_HOME}/perl/bin/perl -I${ORACLE_HOME}/perl/lib -I${ORACLE_HOME}/bin ${ORACLE_HOME}/bin/dbSetup.pl -J-D${CVU_OS_SETTINGS} "$@"   # bug 33519960 - support paths with whitespaces
else
  if [ -d $ORACLE_GSM_PATH ]; then
    ${ORACLE_HOME}/perl/bin/perl -I${ORACLE_HOME}/perl/lib -I${ORACLE_HOME}/bin ${ORACLE_HOME}/bin/dbSetup.pl "$@"      # bug 33519960 - support paths with whitespaces
  else
    ${ORACLE_HOME}/perl/bin/perl -I${ORACLE_HOME}/perl/lib -I${ORACLE_HOME}/bin ${ORACLE_HOME}/bin/clientSetup.pl "$@"      # bug 33519960 - support paths with whitespaces
  fi
fi

Basically here the logic:

  • Directory ${ORACLE_HOME}/inventory/Components21/oracle.server exists ➡️ Oracle Database installation
  • Directory ${ORACLE_HOME}/inventory/Components21/oracle.dslm exists ➡️ Global Data Services installation

On my script I simplified by checking:

  • File ${ORACLE_HOME}/bin/clientSetup.pl exists ➡️ Oracle Full client installation

Otherwise is a DB installation, as I don’t expect to use my script in any GDS server.

Extend Swap in Oracle Linux

This entry was posted in Linux Oracle 19c and tagged Oracle Linux 9 on by

The client has also configured a small Swap mountpoint, when looking at all memory available on the server. Oracle documentation says this:

The VM has 116GB memory, and 32GB reserved for HugePages. The actual swap mountpoint is 4GB big and, based on the Oracle Server Configuration Checklist for 19c, the swap mountpoint should be in this case 16GB.

I’m using Oracle Linux 9, xfs filesystems. I’ll increase the swap mountpoint online, with the databases running.

Extend partition from VMWare in Oracle Linux – part 2 2

This entry was posted in Linux and tagged Oracle Linux 9 on by

The client uses VMWare as virtualization platform for the Oracle Database VMs (yes, he is aware of the License implications).

The VM is running out of space in two partitions. The VMWare Admin extended the disks on their platform. Now I need to make this extension visible in Oracle Linux. This things we do once every 10 years, when versions, filesystems and tools already changed.

For this post in 2025, I’m using Oracle Linux 9, xfs filesystems. All operation are online, with databases running.

I divide this post in two parts:

Extend a mountpoint within several partitions in a block device

oracle@vmware-vm01 MIG01C $ cat /etc/system-release

The partition tree is below, and I need to increase the /u01 from 50G to 100G. The disk is /dev/sda

TDE misconfigured and ORA-28353: failed to open wallet

This entry was posted in Oracle Oracle 19c Oracle 23ai Security TDE on by

I did script the TDE wallet configuration for my client.

  • Script 1 – Set the static parameters TABLESPACE_ENCRYPTION and WALLET_ROOT in the spfile.
  • Script 2 – Restart the database
  • Script 3 – Create the wallet, open the wallet, set the Masterkey, create the autologin wallet.

When running this 3rd script on a database it failed on the second command:

SQL> ADMINISTER KEY MANAGEMENT CREATE KEYSTORE IDENTIFIED BY  "wallet_password";
keystore altered.

SQL> ADMINISTER KEY MANAGEMENT SET KEYSTORE OPEN IDENTIFIED BY "wallet_password";
ADMINISTER KEY MANAGEMENT SET KEYSTORE OPEN IDENTIFIED BY "wallet_password"

Recover missing Masterkey – the famous ORA-28374

This entry was posted in Oracle Oracle 19c Oracle 23ai Security on by

The client plugged a non-encrypted PDB into a CDB with TDE Encryption Wallet enabled. All works fine, we can read the data. However when trying to create a tablespace we get:

CDB1 SQL> create tablespace TBS_NEW;
Error starting at line : 1 in command -
create tablespace t1
Error report -
ORA-28374: typed master key not found in wallet
28374. 0000 -  "typed master key not found in wallet"
*Cause:    You attempted to access encrypted tablespace or redo logs with a typed master key not existing in the wallet.
*Action:   Copy the correct Oracle Wallet from the instance where the tablespace was created.

What is wrong?

Encrypt the whole Oracle database online with TDE

This entry was posted in Oracle Oracle 19c Security on by

Some programs are part of Oracle ISV – Independent Software Vendors – program and include various types of Oracle licenses. This allows to install the application database in various Oracle configurations. At my customer, the software includes Advance Security Option Oracle license. This was the reason we decided, even before moving to the cloud, to encrypt the database.

Here is a summary on how to perform full online encryption (TDE) of a database. The process is quite simple, but there are known surprises you might want to avoid.
