syscheck Command—Display and Verify System Resources

Permission required: Installation owner, system administrator.

The syscheck command displays process and system resources and verifies that there are enough resources to run Ingres as currently configured.

If resources are sufficient, syscheck prints a confirming message and continues. If resources are insufficient, syscheck displays the resources needed, prints an error message, and exits with an error status.

Ingstart calls syscheck after the system is configured and before starting the servers, so you typically will have no need to call this command directly. However, if system resources have changed since installation, you can use this command to see if you are reaching operating system resource limits that might cause the system to fail.

If you use this command, run it after you have configured your system because syscheck reads the locking and logging parameters before it checks for resources.

The syscheck command has the following format:

syscheck [-v] [-ofilename] [-help]

• -v

  Displays messages on all (not just the insufficient) resources (verbose mode).

• -ofilename

  Indicates that syscheck output is to go to the specified filename.

• -help

  Displays command syntax online.
