Esta página da IBM parece ter tudo o que você precisa saber sobre arquivos core dump no AIX.
O comando que você está procurando parece ser chcore
. Aqui está um trecho da página:
A central core file repository can be set up for all accounts on the system, but each account may override the default and install a custom repository. Select a file system with plenty of free space for this repository. All accounts will need read and write access to this directory. To prevent users from deleting core files created by other users, the sticky bit should be enabled. Permissions on this directory should normally be 1777, the same as for
/tmp
.To set up a system-wide core file repository with unique core file naming, run the following commands as root:
$ cd /path/to/filesystem $ mkdir corefiles $ chmod 1777 $ ./corefiles $ chcore -p on -n on -l ./corefiles
Note: Add the option -c on to turn on core file compression. The settings will only be effective for newly logged in accounts and will persist across reboots.
To override the system-wide default repository and set up a repository for a specific user, run the following commands as the user:
$ mkdir ~/corefiles $ chcore -p on -n on -l ~/corefiles
