Known Issues in Chef Client 12.0 & AIX

• Our standard bootstrap procedure doesn't work (not that I think many folks on AIX will use it). A couple problems:
  • Omnitruck doesn't understand BFFs and has invalid syntax for uname: chef/omnitruck#72
  • Bootstrap SSH fails with SSH debug returns "cipher_init: EVP_CipherInit: set key failed for aes128-cbc (when running in -VV) -- it will also fail to negotiate other cipher suites like 3des-cbc
    • Only fix I've found so far is to installp -u security.pkcs11. The one suggested by IBM does not work: http://www-01.ibm.com/support/docview.wss?uid=isg3T1019142
    • Maybe there's a patch for this. My LPAR is 7100-02-04-1341 which isn't the latest SP.
    • security.pkcs11 is safe to remove as it has to do with hardware encryption devices (a rare use case). Customers can contact IBM if they have a hardware crypto device and need this package
  • Bootstrap assumes bash is available on the system so you get something like `k

Deep Dive: PostgreSQL on AWS

When loading data

• disable backups (backup_retention=0)
• disable multi-AZ and autovacuum
• pg_dump -Fc (compressed) and pg_restore -j (parallel)
• Increase maintenance_work_mem

Chef Client 12 uses the UTF-8 locale. By default, BOS doesn't include it so Chef will throw warnings. Here's how you install it.

You need at least the AIX media (first disc), or copy all the files in /installp/ppc/*EN_US* somewhere on your LPAR. Let's say it's /tmp/rte

It's recommended that you use smit to install this charset so any WPARs you have also get the charset applied.

From a root shell type:

` $ smit lang
