Valid for
Coordinator
Description
Use READER
to trigger the creation of a Reader process to monitor a local trail and communicate with the system Coordinator. The HOST
parameter from GLOBALS
file will be used to determine the location of the object to be used. Typically this will be the installation location for Oracle GoldenGate, but if it varies the PROGRAM
option can be used to point to another object.
Syntax
READER EXTTRAIL trail_name [, PROCESS process_name], [, CPU primary_cpu] [, BACKUPCPU cpu] [, PRI priority] [, PROGRAM program_name]
EXTTRAIL
trail_name
The fully qualified identifier of the trail that will be monitored by the Reader. This is a required entry.
PROCESS
process_name
The process name of the associated Reader.
Oracle GoldenGate recommends you allow the process name to be generated by the system. However, if you must specify an alternative process, PROCESS
process_name
lets you do so.
CPU
primary_cpu
Specifies the primary CPU on which the Reader process runs. The default is the CPU on which Manager runs.
BACKUPCPU
cpu
Specifies an alternate CPU on which the process runs if the primary CPU becomes unavailable.
PRI
priority
The NonStop priority for the process. This defaults to the priority assigned to the TACL process underlying the ADD
.
PROGRAM
program_name
This specifies the name of the program that Manager uses when starting the Reader process. Typically this is not entered, and Manager uses the HOST
parameter in the GLOBALS
files to determine the Oracle GoldenGate installation subvolume as indicated in the GGSSUBVOL
option.
Example
The following example identifies a Reader process to monitor Oracle GoldenGate trail AA on \NY. READER EXTTRAIL \NY.$DATA5.GGSDAT.AA, PROCESS $GGRD1, CPU 1, PRI 180
