  • 1.  CA 11.1.7 Upgrade - Unable to Connect to Content Store

    Posted Tue December 22, 2020 12:42 PM

    I have completed an upgrade to CA 11.1.7 FP1 from CA 11.0.13.

    Upon trying to connect to the Content Store I am getting the following message:

    [Content Manager database connection]
    [ ERROR ] The database connection failed.
    [ ERROR ] Content Manager is unable to connect to the content store. Verify that the database connection properties in the configuration tool are correct and that when you test the connection, the test is successful.

    My Content Store is on Oracle and the connection defined as:

    (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCPS)(HOST=server.xxx.yyyy.com)(PORT=2484)))(CONNECT_DATA=(SERVICE_NAME=database.oracle.yyyy.com)))
    Whilst certain entities have been obfuscated, this same connection worked previous to the upgrade.

    We use SSL and SSO.
    Other than running an over-the-top install, I have made no other changes to the configuration.

    Note: I am also getting an [Check NIST 131A conformance warning] while starting Cognos services message, but as this is only a warning I want to resolve the database connection issues first.

    Thanks in advance.

    Hello Adam,

    I guess the first check is that the drivers folder still has the Oracle JDBC driver available. Set up database connectivity for an Oracle logging database (ibm.com)

    If so then the server log might have more detail about the error.

    Hi Adam,

    Did you install 11.1 R7 on 11.0 R13 ?

    Did you install on a new computer ?

    Did you check network flow are open between Cognos and Oracle ?

    What is your Content Store Configuration in Cognos Configuration ?

    Did you check with your DBA is there is any security on Oracle side ?

    Does Oracle client is installed ?

    Did you put the Oracle driver in <cognos install>\drivers folder

    ...

    Regards,

    Hi Adam,

    depending what your configuration is.

    Did you install Cognos 11.1 R7 on 11.0 R13 ?

    Did you check network port is correctly open between Oracle and Cognos ?

    Did you install Oracle client on Cognos computer ?

    Did you put the driver in the correct folder ?

    Did you double check login/password

    etc...

    regards,

    Answers below:

    No, I did not do the CA 11.1.7 upgrade on CA 11.0.13 first.
    It is my understanding (or at least was) that Cognos fix packs are now a full over-the-top install so that I could skip the CA 11.1.7 install and just do the CA 11.1.7.1 install.

    As this was an over-the-top install over a fully functional CA 11.10.13 environment, all ports, clients, drivers, and logins/password were retained from the the original previous CA 11.0.13 install - And, they were all working satisfactorily then.

    Hi,

    I have reviewed the release note for the 11.1.7 FP1, there was a fix for : 

    PH28426 :  CAN'T LOAD METADATA FROM ORACLE DATABASE SYNONYMS CREATED FOR A USER FROM A DIFFERENT SCHEMA

    Reference : https://www.ibm.com/support/pages/system/files/inline-files/ibm_fixlist_cognos_analytics_1117fp1_2.pdf

    Since you are doing an upgrade from 11.0.13, I would suggest (assuming you have a test environment), to go the at most 11.1.7 (without FP), or even lower than that, to know where your configuration breaks.

    Adam,

    Since you are using TCPS could it be some problem with the certificates? They should have been preserved with an over-the-top upgrade but might want to check into it. Also, the NIST warning means that you probably need to increase the strength of the confidentialities to 256-bit under Cryptography > Cognos and may have to remove weaker ciphers there as well. NIST is an SSL standard that requires strong encryption basically.

    I certainly understand that it might be certificate related.
    As for the NIST, this is just a warning and I will upgrade the cryptography once I have connection to the Content Store.

    Due to the Holiday, I am currently having my network team restore the pre-upgrade images with CA 11.0.13.
    Interestingly, on the first server, they restored the image and I was able to connect to the Content Store.
    However, I have not restored the pre-upgrade versions of the databases!
    It's as if the Content Store was NOT upgraded to the new release - Any thoughts on this would be much appreciated!

    Therefore, after the Holiday break, I am going to re-attempt the upgrade, but I will take a full Content Store export prior to upgrade and then have the Content Store dropped and re-created empty. Then, restore the content store by doing an import.
    I hope this will give me better results.\

    Thanks for everyone's help.
