In this Document
Created from <SR 3-12890602024> Applies to:Oracle ZFS Storage ZS3-2 - Version All Versions and laterOracle ZFS Storage ZS3-4 - Version All Versions and later Oracle ZFS Storage ZS3-BA - Version All Versions and later Oracle ZFS Storage ZS4-4 - Version All Versions and later Oracle ZFS Storage Appliance Racked System ZS4-4 - Version All Versions and later 7000 Appliance OS (Fishworks) SymptomsBUI/CLI access to the ZFS-SA is slow.
CauseOracle Enterprise Manager with EM plugin version below 12.1.0.6.0 is being used to monitor the ZFS-SA. EM plugin that is running below 12.1.0.6.0 uses ssh to the ZFS SA for monitoring and it is not efficient. From the shell, there will be lots of aksh process from user orarom. zfssa# ps -ef | grep orarom orarom 8901 8900 0 03:34:41 ? 0:24 /usr/lib/ak/tools/aksh -l -N4 orarom 3035 3034 0 Apr 27 pts/20 0:01 /usr/lib/ak/tools/aksh -l -N4 orarom 9142 9141 0 03:56:14 ? 0:13 /usr/lib/ak/tools/aksh -l -N4 orarom 6229 6228 0 Feb 13 pts/3 0:01 /usr/lib/ak/tools/aksh -l -N4 orarom 21281 21280 0 Mar 24 pts/16 0:01 /usr/lib/ak/tools/aksh -l -N4 orarom 6227 6226 0 Feb 13 ? 0:40 /usr/lib/ssh/sshd orarom 6228 6227 0 Feb 13 pts/3 0:00 -aksh-wrapper orarom 24347 24346 0 Mar 05 pts/14 0:00 -aksh-wrapper root 9399 9198 0 04:19:27 pts/34 0:00 grep orarom orarom 9159 9158 0 Feb 28 ? 0:34 /usr/lib/ssh/sshd orarom 7085 7084 0 Apr 09 pts/21 0:01 /usr/lib/ak/tools/aksh -l -N4 orarom 7912 7911 0 Mar 30 pts/18 0:00 -aksh-wrapper orarom 9160 9159 0 Feb 28 pts/11 0:00 -aksh-wrapper orarom 9161 9160 0 Feb 28 pts/11 0:02 /usr/lib/ak/tools/aksh -l -N4 orarom 24348 24347 0 Mar 05 pts/14 0:01 /usr/lib/ak/tools/aksh -l -N4 orarom 7911 7910 0 Mar 30 ? 1:24 /usr/lib/ssh/sshd orarom 7913 7912 0 Mar 30 pts/18 0:02 /usr/lib/ak/tools/aksh -l -N4 orarom 24346 24345 0 Mar 05 ? 1:02 /usr/lib/ssh/sshd orarom 9140 9139 0 03:56:14 ? 0:00 /usr/lib/ssh/sshd orarom 21280 21279 0 Mar 24 pts/16 0:00 -aksh-wrapper orarom 21279 21278 0 Mar 24 ? 0:27 /usr/lib/ssh/sshd orarom 25461 25460 0 May 28 ? 0:07 /usr/lib/ssh/sshd orarom 7084 7083 0 Apr 09 pts/21 0:00 -aksh-wrapper orarom 9141 9140 0 03:56:14 ? 0:00 -aksh-wrapper orarom 7083 7082 0 Apr 09 ? 0:21 /usr/lib/ssh/sshd orarom 3031 3030 0 Apr 27 ? 0:16 /usr/lib/ssh/sshd orarom 3034 3031 0 Apr 27 pts/20 0:00 -aksh-wrapper orarom 9392 9391 0 04:19:04 ? 0:00 /usr/lib/ssh/sshd orarom 25466 25465 0 May 28 pts/30 0:01 /usr/lib/ak/tools/aksh -l -N4 orarom 8900 1 0 03:34:41 ? 0:00 -aksh-wrapper orarom 25465 25461 0 May 28 pts/30 0:00 -aksh-wrapper orarom 9394 9393 0 04:19:05 ? 0:01 /usr/lib/ak/tools/aksh -l -N4 orarom 9393 9392 0 04:19:05 ? 0:00 -aksh-wrapper
