Chapter 2 Installation Steps : Post-Installation Tasks

Post-Installation Tasks
This section describes tasks that you might have to perform after completing the TIBCO ActiveSpaces installation.
Enabling Processing of Large Files with Shared-Nothing Persistence
This section discusses considerations for handling large files when using shared-nothing persistence.
Setting Resource Limits (ulimit) for the Current Shell
On some systems, the administrator might have set small ulimit values for resources that affect execution of ActiveSpaces processes, such as data segment size, stack size, and virtual memory. It is advisable to set these values to unlimited and let processes receive maximum available memory from the available resources.
You can use the following commands to change resource values to unlimited:
ulimit -d unlimited
ulimit -s unlimited
ulimit -v unlimited
Procedure for Enabling Processing of Large Files
For shared-nothing persistence, ActivesSpaces is enabled to work with files larger than 2 GB.
If you are implementing shared-nothing persistence on a UNIX or Linux platform, complete these steps before starting seeders:
1.
ulimit -a
2.
If the ulimit command does not return unlimited, enter the following to set the user resources (including file length) to unlimited:
ulimit -f unlimited
3.
a.
- The default directory is the home directory of the user running the ActiveSpaces application. If that is where you want the shared nothing files written, you do not need to change the directory.
- Set the AS_DATA_STORE environment variable to point to the directory where the shared-nothing persistence files are to be stored.
- Run as-agent with the -data_store parameter to specify the data store directory:
as-agent -data_store <path>
where path specifies the directory path for the data store directory.
