Steps to enable Monitoring in Classic 19c GoldenGate 


Performance Metric server short form is PMSRVR 

Performance Metric Server is available in GoldenGate classic from version 12c(12.1.3.x) .
Before this version we need to write our own shell scripts to monitor if GoldenGate process are running or in ABEND mode .
With Classic architecture and MicroServices Architecture in 12c on wards Oracle
has done great job of monitoring the GoldenGate with help of PMSRVR utility .
By default it is available in Microservices installation

There are different tools available for Monitoring the GoldenGate
1.Oracle Enterprise Manager plugg-in with Monitor Agent
2.Performance Metric Server

What is the use of PMSRVR ?
  • You can monitor it from Browser this means you don't need to login to GoldenGate server and check it 
  • GUI based tool 
  • Based on Berkeley DB which is a embedded key-value database libraries providing scalable high-performance data management services to applications.
 Some of the files important to PMSRVR
  • Resources it get it from /u02/ogg_trg/dirprm/pmsrvr-resources.dat'
  • config Path: /u02/ogg_trg/dirprm/pmsrvr-config.dat
  • global Path: /u02/ogg_trg/dirprm/global.dat

Now lets configure it 
 
Login to ggsci
1. GGSCI (ggate1) 40> edit param ,/GLOBALS

ENABLEMONITORING UDP HTTPPORT 9004
2.save the file

ENABLEMONITORING is the parameter
UDP is protocol and HTTPPORT is 9004 is in one line

Remember to stop mgr and exit ggsci  else it will not work !!!

ggsci > stop mgr
ggsci > exit
./ggsci
ggsci > start manager

3.Start other process
GGSCI (ggate1) 8> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING                                          
JAGENT      STOPPED                                          
PMSRVR      RUNNING                                          
EXTRACT     RUNNING     EXTINT      00:00:00      00:37:33   
EXTRACT     RUNNING     PINT        00:00:00      00:00:09   


Open the browser

To access the PMSRVR page, just navigate to http://hostname:port/groups
This is the landing page for checking the status

http://ggate:9004/groups



You can get more information with 
GGSCI (ggate1) 19> info PMSRVR

PM Server is Running (HTTP Port TCP:ggate1.9004, Process ID 11687, Datastore BDB)

GGSCI (ggate1) 30> status PMSRVR

PM Server is Running (HTTP Port TCP:ggate1.9004, Process ID 11687, Datastore BDB)



Here you come to know which Datastore it is using (BDB -
Berkeley DB which is a embedded key-value database ) so its fast and does not consume much memory of host .

You can also check the PMSRVR.log file for more information location is same as your ggserror.log 


[oracle@ggate1 ogg_trg]$ ls -lart *.log
-rw-r----- 1 oracle oinstall 80718 Jan 16 23:07 ggserr.log
-rw-r----- 1 oracle oinstall 23712 Jan 16 23:32 pmsrvr.log
[oracle@ggate1 ogg_trg]$ pwd
/u02/ogg_trg



Hope this help in monitoring the GoldenGate 19c Classic infrastructure .

Configuring GGSCI Command Security CMDSEC in GoldenGate 19c classic

Configuring GGSCI Command Security CMDSEC You can establish command security for Oracle GoldenGate to control which users have access to which Oracle GoldenGate command line functions. For example, you can allow certain users to issue INFO and STATUS commands, while preventing their use of START and STOP commands. Security levels are defined by the operating system's user groups. To implement security for Oracle GoldenGate commands, you create a CMDSEC file in the Oracle GoldenGate directory. Without this file, access to all Oracle GoldenGate commands is granted to all users. As GoldenGate administrator you have team of GoldenGate users who has different levels of skill sets and responsibilities ,how do you manage these Users with correct responsibilities is in GoldenGate classic 19c ? CMDSEC (Command line GGSCI Security) For e.g. A person with monitoring responsibility should not able to use START and STOP commands But the same person should able to use INFO an

How to check syntax of parameters in parameter files without logging to GGSCI prompt ? Version :GoldenGate 12.2 new feature Utility Name:checkprm Location:GoldenGate Home You are working on GoldenGate environment and want to build and test the parameter files like 1.Manager parameter file 2.Extract parameter file 3.Datapump parameter file 4.Replicat parameter file So one way to do this is to do edit <Parameter file Name> and save and test it. If there is any typo you get error and then once again you need to go back to edit <Parameter file Name> and that also in GGSCI prompt . Its cumbersome and time consuming , Oracle Goldengate 12.2 onward it come up with an utility called checkprm Which you can run as below and check if everything in parameter files are syntactically correct or not [oracle@ggate1 ogg_trg]$ ./checkprm ./dirprm/mgr.prm -C mgr -v Parameter file validation context: component(s): MGR mode(s)     : N/A platform(s) : Linux database(s) : Oracle 12c ./di
