nmon statistics shows permanently numperm < minperm
minperm is a threshold, for that if numperm reaches or falls below would make LRUD steal memory from running processes which would be very bad. While numperm is above minperm, everything is ok and only cached files are cleared for memory needs. To get not in such a bad situation, minperm is... -
Extract data from two files and create another
Looking at it again yes, you're right. Something like grep -vf ... but with awk. laters zaxxon -

performance issue 5.3
Glad you found it :) Though I would put the aio0 maxreqs up to 32768 just in case you hit the current limit of 4096. Also raising the minservers to 10 and the maxservers to 100 can improve performance in peak times. But as said, maybe monitor AIO with nmon -A and iostat -A. laters zaxxon -
performance issue 5.3
Looks fine so far, maybe check number of AIO-servers active with nmon -A and AIO-requests with iostat -A. Maybe a higher value for maxservers and minservers might help a bit for IOs, depending what you see with nmon -A on busy times. Also the maxreqs should be set to a higher value just in case... -
performance issue 5.3
And a 3rd one @khalida So run-queue should be ok. The lot of entries in the blocked-queue might come from locks in the database I guess. Observed similar on our heavy traffic Oracle DB. laters zaxxon -
performance issue 5.3
Sorry forgot the code tags; anyway the wait process are just from the kernel to fill up the idle time. They don't consume any noticable performance. Nothing to worry about. laters zaxxon -
performance issue 5.3
Please post the output of the following commands: vmstat 1 10 vmo -x| grep -iE "minperm|maxperm|lru_file|minfree|maxfree" lsdev -C| grep aio lsattr -El aio0 vmstat -v| tail -7 ioo -x| grep -iE "pv_min_pbuf|j2_maxPageReadAhead|j2_nBufferPerPagerDevice|j2_dynamicBufferPreallocation" laters zaxxon -
restrict access to performance tools
How do you prevent, like ciman already said, that the users just copy the binary from another box locally to their home? ciman wrote: laters zaxxon -

Changing multiple HACMP passwords
cl_chpasswd is a shell script - I didn't look deeper into it but maybe you can have look into it's options etc. or feed it with a while read loop. laters zaxxon -
Script to edit Crontab
@Heston If you have a script/tool to restart the cron on your OS, use it. As I am on AIX like Columb, I do it with killing cron too, as init just respawns it and there are no such scripts/tools (at least I never found any). Btw. which OS are you using (didn't find it in the posts)? laters zaxxon- zaxxon

IHS 6.1 - problem with symlinks / symbolic links / softlinks
Ok, seems to be an issue on only one server and a particular installation. First I thought it's because of a permissions problem, but currently it's working on another AIX box... nvm, thank you though. laters zaxxon -
IHS 6.1 - problem with symlinks / symbolic links / softlinks
Just found out, that it works with soft links on files, but not on directories. Too bad I need directories linked and being displayed in the index :/ laters zaxxon -
IHS 6.1 - problem with symlinks / symbolic links / softlinks
Hello, I got an IHS 6.1 installed and want to publish a directory with an index of files, directories and symlinks / symbolic links / soft links, last ones being created with the usual Unix command "ln -s .... ....". In httpd.conf I've tried following for that directory: Options Indexes...
