The objective of this post is to demonstrate how to gather existing GoldenGate deployment status. The rationale is to gather all the pertinent information for GoldeGate deployment using RAC in order to relocate the GoldenGate trail from DBFS to ACFS file system. Although the deployment gathering can be performed manually, I have chosen to script as much of the process as possible since this will be performed for multiple environments versus just one. Implementation created is also reusable for troubleshooting; hence, the work is not in vain.
WARNING: gi.env is used to dynamically source ASM instance provided the following requirements are met:
Last character from short host name must match ASM instance number. Acceptable: racnode-dc1-1/+ASM1 and racnode-dc1-2/+ASM2 UNAcceptable: host05/+ASM1 and host06/+ASM1 I chose to create gi.env so that the script can be deployed in any environment with the least possible change as long as the requirements above are met. $ cat gi.env
set +x
unset ORACLE_UNQNAME
h=$(hostname -s)
n=1
. oraenv <<< +ASM${h:${#h} - $n}
export GRID_HOME=$ORACLE_HOME
env|egrep 'ORACLE|GRID'
sysresv|tail -1
From ogg_status.sh, grid (+ASM[n]) is sourced using gi.env. $ cat ogg_status.sh
#!/bin/sh -ex
# MDinh : Feb 2019
. ~/working/dinh/gi.env
set -x
agctl query releaseversion
agctl query deployment
agctl status goldengate gg_xx
agctl config goldengate gg_xx
crsctl stat res -t|egrep -A2 'acfs|dbfs|xag'
crsctl stat res -t -w 'TYPE = ora.acfs.type'
crsctl stat res -t -w 'TYPE = xag.goldengate.type'
crsctl stat res -t -w 'TYPE = app.appvipx.type'
crsctl stat res -t -w 'TYPE = local_resource'
crsctl stat res -w "TYPE = xag.goldengate.type" -p|awk -F'=' '$2'
exit
Ideally, instead of hard coding goldengate instance_name (gg_xx) it can be determined using:
$ crsctl stat res -w 'TYPE = xag.goldengate.type'
NAME=xag.gg_xx.goldengate
TYPE=xag.goldengate.type
TARGET=ONLINE
STATE=ONLINE on host01
For now, I did not want to complicate the script too much. Here is a demo from the script. Do you see any potential issues from the output?
$ ./ogg_status.sh
+ . /home/oracle/working/dinh/gi.env
++ set +x
ORACLE_SID = [+ASM1] ? The Oracle base remains unchanged with value /u01/app/oracle

In conclusion, scripting the process with some simple automation will provide better efficiencies to review and troubleshoot GoldenGate deployment for RAC on DBFS or ACFS.
