ZFECB-Display Active ECB Information

Use this command to display a list of active entry control blocks (ECBs) or a formatted display of a particular ECB and any data event control blocks (DECBs) attached to that ECB.

Requirements and Restrictions

You can only enter this command in a basic subsystem (BSS), although it can be used to display information about non-BSS ECBs.

Format




time
is the number of seconds or minutes for which you want to check active ECBs. Specify a 3 digit number from 000-999. If you do not specify any additional parameters, a list of ECBs that are older than the specified time, in seconds, is displayed.

M
displays a list of ECBs that are older than the input time in minutes.

H
displays a list of ECBs that are older than the input time, in seconds, that are also holding one or more records.

svcname
is a supervisor call (SVC) mnemonic. This parameter displays a list of ECBs that are older than the input time, in seconds, and whose last SVC issued was the SVC entered.

address
is a valid 6- or 8-character ECB system virtual memory (SVM) address. This parameter displays a formatted version of the specified ECB.

*lniata
displays a list of active ECBs, where lniata is the terminal address.

Additional Information

Enter ZFECB without any parameters to display the state change ECB.

Examples

The following example shows an active ECB display, where:

 ECB 
is the SVM address of the active ECB.

 SVC 
is the primary SVC last issued by the ECB.

 PROG 
is the name of the program that issued the last SVC.

 TIME 
is the amount of time, in minutes (0000) and seconds (00), that this ECB has been active.

 TYPE-ECB 
is the method in which the ECB was created. If it was created with a create macro, the display also shows the name of the creating program.

 IO 
indicates if input/output (IO) is outstanding for this ECB.

 BLK 
is the number of core blocks in use by this ECB.

 HLD 
is the number of records held by this ECB.

 PSW 
is the program status word (PSW) as last saved in field CE1PSW of the ECB.

 IS 
is the I-stream number that is currently assigned.

 ACTIVATION NUMBER 
is the activation number of the program currently in use by this ECB.
