    This error is happening at a client site. I am not exactly sure of their version - probably 11.0.13 or 11.0.9.

    DPR-ERR-2019. The dispatcher cannot service the request at this time. The dispatcher is still initializing. 

    happens when they are signing on. i found some decent google results yesterday but am having trouble today (on a different machine) getting decent hits today. Anyone have any info on this? 

    Also, where inside IBM is the best place to search for cognos error messages? I usually go to google. But seems somewhere in IBM should be a good place to look.

    looking at the cognosserver.log

    do these files get updated automatically? very recent dates and a bkup? think i could try swapping the CAMKeystore and CAMKeystore.bkup files?

    Hi,

    This message is because your APP tier/dispatcher is initializing, after a crash, for example.

    It could be happen because you may set less memory to WLP in your Cognos Configuration.

    Default is 8GB, that is too low for production environments.

    Try increasing memory that can be used: Cognos Configuration > Environment > IBM Cognos Services > IBM Cognos > Maximum memory for Websphere Liberty Profile in MB.

    If you don't have a distributed installation (Content/Data Tier, App Tier and GW), it is recommend, mainly first two.

    OK, a bit beyond my knowledge. But ... why is the cognosserver.log message "contents of the keystore 'E:/Program Files/IBM/CognosAnalytics/StoreXX/configuration/certs\CAMKeystore'. Reason: java.io.IOException: stream does not represent a PKCS12 key store"  complaining about a PKCS12 key store, when it seems that I have jks (look at cert screen print). IBM doc says that there would be an PKCS12 file extension and i have a jks extension. Honestly, i do not know what either of these mean. But when i went to look at the certs in IBM Key management I had to enter jks type to view them. What makes it think that i have PCKS12?

    Another possibility is that file became corrupt for some reason. The most common is to run out of disk space. If the memory is undersized, especially for dynamic cubes or DMR models, then Cognos Analytics is forced to cache a lot of files to the ../temp and ../data folders. This is a good reason to separate them to another drive or file system.

    Hi Brenda

    In the \ibm-jre\jre\bin there is an ikeyman application that you can use to look at the cacert, default pw is NoPassWordSet.  Likely there will be a cert with the name of the server in it. You can check to see if the signer certificate is expired. 

    The default certificate lifetime set in the configuration is 730 days but configurable. 

    You should see errors just saving the configuration if the certs are expired but I don't know if you have tried that or just started with the services option or a bat file.
