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.
Note: The syscheck command returns limited information in Windows and VMS environments.
The syscheck command has the following format:
syscheck [ -f ] [ -v ] [ -c ] [ -kernel_bits ] [-ofilename]
‑f
Forces syscheck to revert to the old behavior and return FAIL if the system does not have sufficient resources to run Ingres.
(Currently, syscheck exits OK, rather than FAIL, if it determines that the system does not have sufficient resources to run Ingres. If II_DISABLE_SYSCHECK is set, then it immediately exits OK.)
-v
Displays messages on all (not just the insufficient) resources (verbose mode).
‑c
(Linux only) If certain kernel parameter settings are less than needed to run Ingres, print the kernel parameters that need to be changed.
‑kernel_bits
Returns 32 when run on a 32-bit operating system (not Windows or VMS). Returns 64 when run on a 64-bit operating system (not Windows or VMS).
-ofilename
Indicates that syscheck output is to go to the specified filename.
