TSOE_OPERSEWAIT_SETTING

Description:

This check will report whether the current setting of OPERSEWAIT matches the preferred installation setting.

Reason for check:

The default setting for OPERSEWAIT (in IKJTSOxx parmlib member) prior to z/OS® V2R2 is ON which means the SEND command will wait for a users VTAM buffer to free up and the message to be sent, instead of failing the command when a buffer is unavailable. When the SEND command is holding a resource such as the SYSIKJBC exclusive enqueue on the broadcast data set, this can hold up any TSO/E LOGONs on the system. Beginning in z/OS V2R2 the default setting of OPERSEWAIT is OFF.

z/OS releases the check applies to:

z/OS V2R2 and later.

User override of IBM values:

The following sample shows the defaults for customizable values for this check. Use this sample to make permanent check customizations in an HZSPRMxx parmlib member used at IBM Health Checker for z/OS startup. If you just want a one-time only update to the check defaults, omit the first line (ADDREPLACE POLICY) and use the UPDATE statement on a MODIFY hzsproc command. Note that using non-POLICY UPDATEs in HZSPRMxx can lead to unexpected results and is therefore not recommended. End of change
