IBM Enterprise Console Adapter Administrator Roles for Windows NT, Low Memory Registry Variables

drive:\adapter_dir, where drive and adapter_dir are the drive and directory, respectively, that contain the adapter executable files and run-time files. Only change the TECInstallPath variable if you move the adapter executable files and run-time files after you have installed the adapter.

Low Memory Registry Variables

When enabled, this feature checks the amount of available memory before the adapter attempts to send an event. If the amount of free memory is extremely low, the adapter returns to a suspended state until more memory is available, which prevents the adapter from failing. However, because of the amount of resources this consumes, only enable this feature when available memory is so low that the adapter is failing and you have no other way to solve the problem.

To enable this feature, you must set at least one of following registry variables in the \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\TECNTAdapter\ registry path:

yellow_alert_limit

When free memory is below this level, the adapter sends a warning that indicates the adapter might return to a suspended state until more memory is available and lists the amount of free memory. The default value is 40 Mb.

red_alert_limit

When free memory is below this level, the adapter sends a warning and lists the amount of free memory, then returns to a suspended state for 1 minute. After 1 minute, the adapter checks free memory again; if free memory is still below this level, the adapter returns to a suspended state for another minute and repeats until free memory is higher than this value. The default is 20 Mb.

emergency_memsize

This is the amount of memory the adapter keeps in reserve for low memory situations. When the red_alert_limit is reached, the adapter frees this memory to make sure there is enough memory available to send the red_alert_limit warning. The default is 2 Mb.

Any values, which you do not set, use the default values when you enable this feature. The adapter only checks these values at startup.

Adapter Administrator Roles for Windows NT

Both the service and non-service version of TME adapters on Windows NT run under the local SYSTEM account (the built-in Windows NT account). You must create a Tivoli administrator that grants the Tivoli role of senior (or higher) to the SYSTEM account so that the adapters can send events to the event server. Otherwise, the TME adapters exit on the first event.

To create a Tivoli administrator with senior (or higher) authorization role, do the following:

1.Select Create Administrators from the Administrators icon.

2.You can leave the User Login Name and Group Login Name fields blank.

3.Type in SYSTEM in the Set Login Names dialog.

4.Select senior (or higher) in the Set TMR Roles dialog.
