  • 1.  Unexpected RSS authentication failure for 'leap16_2_c_tcp' during the Initialization Phase.

    Posted Sun April 26, 2026 08:32 AM

    Just an observation really, occasionally on a fully functioning cluster the following is reported leaving the RSS instance in Fast Recovery ...  a simple restart (onmode -ky; oninit) of the RSS and all is good ...

    13:17:22  ERROR on the following statement SQLCODE:-243 ISAM:-154
    select * from rss_tab_int where rss_servername = 'leap16_2_c_tcp'
    13:17:22  Unexpected RSS authentication failure for 'leap16_2_c_tcp' during
            the Initialization Phase.

            Ensure that:
              1. You are using the correct server name.
              2. If using passwords, that you are using the correct password.
              3. The HA_ALIAS setting is correct.
              4. You have run the 'onmode -d add RSS' command at the primary to
                 register the RSS node attempting to connect.

    Hummm, any circumstances that could explain this locking conflict? Any other RSS connecting/definition/deletion activity around such time? Anything in logical log for the rss_tab_int table?

    Also, I guess that instead of restarting such RSS a simple "onmode -d RSS <source_name>" might be sufficient to initiate a new connection attempt.

    Greetings!

    Hi ya 

    There is an HDR and another RSS starting around the same time. If one follows the message one could go down a rabbit hole ;) If I get this again I will try the onmode command to see if it kicks back to life.

    I had the same issue and found a simple solution: change DBSERVERNAME and DBSERVERALIAS, so that the RSS connection is using the DBSERVERNAME.
    I do not know why, but this worked for me

    Mit freundlichen Grüßen / Kind regards

    If HA_ALIAS is set and DBSERVERNAME is set to the relevant TCP connection and all onmode commands use the same setting as the HA_ALIAS then the issue is transient due to locking on a specific table as reported in the message I placed above when starting more than one HDR / RSS around the same time.

    Not even sure the setting of the DBSERVERNAME / ALIAS is relevant if HA_ALIAS is set ... but I tend to set it to the TCP connection (and all onmode commands should be referencing HA_ALIAS).

    Hi JJ,

    since you only posted the actual errors, what would've been the overall timing there, esp. how much time passed from that RSS's connection attempt to the actual error (ISAM -154 indicating a lock timeout)?  I'm wondering whether a simple retry upon hitting -154 would be advisable there... and what the actual lock timeout is.

    This was a rolling "onmode -uky; oninit" across Primary then HDR, RSS1 and RSS2 ... the attached shows the Primary log ... hopefully you can see the timelines :)
