Standalone IBM Traveler Maintenance Post-9.0.1.7

Beginning with IBM Traveler 9.0.1.8, the NTS_DEFRAG_INTERVAL_DAYS= ini setting is no longer valid.

If the setting is still present in the Traveler server’s ini, you will see the following warning on the server console (and/or in the log) when Traveler starts:

Traveler: WARNING *system Unrecognized IBM Traveler parameter in notes.ini: NTS_DEFRAG_INTERVAL_DAYS

If the server was upgraded with the NTS_DEFRAG_INTERVAL_DAYS= in place, the upgrade process appears to transfer the previously set interval. The same result can be achieved by issuing: tell traveler dbmaint set interval 30

You can then verify the set interval using: tell traveler dbmaint show

Don’t forget to remove the NTS_DEFRAG_INTERVAL_DAYS= setting from your post-9.0.1.7 server’s ini.

In a standalone DB situation where you want to trigger Traveler database maintenance, you can issue the following command at the console: tell traveler DBMaint run

This will set the ini parameter NTS_DEFRAG_ONCE=1 which will trigger defrag at the next Traveler restart. The server will automatically remove the NTS_DEFRAG_ONCE=1 setting after the triggered defrag completes.

Again, in a standalone DB situation, you could automate regularly scheduled defrags to run by:

  1. Using the “tell traveler DBMaint set” commands to set the desired interval, time, day
  2. Creating a Program document that issues the server command, restart task traveler, just after the time set in the command above

TLS For Domino SMTP

Those that are already using or considering enabling secure SMTP sessions using STARTTLS for Domino should either disable it / wait for now (until SPR# MKENA4SQ7R is resolved in an IF or 9.0.1 FP6), obtain hotfix(es) directly from IBM, or risk the inability to deliver/receive TLS with (at least) some @outlook.com addresses.

For those using (or planning to use) TLS, you should also look at adding the SSL_SESSION_SIZE notes.ini setting. When the setting is not used, the value defaults to 5000 and this is too low to prevent errors like:

02/25/2016 12:23:52 PM New SSL session data length of 5121 bytes is larger than the current size of 5000 bytes.
02/25/2016 12:23:52 PM You may want to set the Notes.ini variable SSL_SESSION_SIZE to at least 5121 bytes.

Note that the server suggested the 5121 value in this example (presumably based upon the handshake with the external server) and I’ve been unable, as yet, to find any other scientific method for determining what other value might be better.
