Hi,
I have a fresh installation liveCache 7.6.0 Build 29 on AIX.
Just after the installation, while giving command db_admin or db_warm, I'm receiving below error : (from log file knldiag.err)

memory usage is as below :

Total(MB) 16384.0MB 55296.0MB
Any idea?

Fist, I´d check, if the required operating system patchlevels are there:
Note 720261 - System requirement AIX - liveCache/MaxDB 7.4, 7.5, 7.6
Also check if the OS kernel parameters are set correctly:
Note 628131 - SAP DB / MaxDB operating system parameters on Unix
Basically, this seems to be your error since the system can´t allocate enough memory. Also check the ulimits of the user starting the x_server (see above note also).

Hello Gökhan
For me, it looks like, that some memory depending parameters are set too high. How are CACHE_SIZE, MAXUSERTASKS etc. set?
