Oracle Audio Technologies B31679-01 manual Default installation directories

To increase the maximum data segment (malloc space) a process may use, change the kernel values per_proc_data_size and

max_per_proc_data_size

For example, to change all of these values to 10GB:

1.Create a text file, kernelparams, that contains the following:

per_proc_address_space = 10737418240 max_per_proc_address_space = 10737418240 per_proc_data_size = 10737418240 max_per_proc_data_size = 10737418240

2.Log in as root and run the command:

#sysconfigdb -m -f kernelparams proc

3.You may need to reboot the system after you have made these changes. Alternatively, you can run the command:

#sysconfig -q proc

4.To view the value of the proc kernel subsystem, run the command:

% sysconfig -r subsys ttr=value

Shared memory IPC client connections

Replication

On Tru64 UNIX, to have more than 6 ShmIpc-enabled Client DSN connections per process, you must make changes to the SHMSEG kernel parameter. Kernel parameters can be changed with either the dxkerneltuner interface or the sysconfigdb command.

For replication, TCP send and receive buffers should be increased to a minimum of 512KB. You may need to embed the following commands into a script that can be run at system boot time:

#sysconfig -r inet tcp_recvspace=524288

#sysconfig -r inet tcp_sendspace=524288

Default installation directories

The TimesTen default installation directories for release 7.0 are:

•On Windows, C:\TimesTen\tt70

•On HP-UX, Solaris and Linux, /opt/TimesTen/tt70

•On AIX, /usr/lpp/TimesTen/tt70

TimesTen creates temporary files when large amounts of space in a data store are freed by a transaction. In addition, other TimesTen operations, such as ttRepAdmin -duplicateoperations and large deletes, use the temporary directory when copying files.
