There is no need to use on database if the instance names are unique across primary and standby environments.

You might ask, why are instance name not the  same on primary and standby?

I don’t know.

show instance verbose hawka1 on database hawka
show instance verbose hawka2 on database hawka

show instance verbose hawkb1 on database hawkb
show instance verbose hawkb2 on database hawkb

The InconsistentProperties monitorable property returns a table that shows all properties whose values contained in the broker configuration file are inconsistent with the values in the corresponding server parameter file or the runtime values.

show database hawka InconsistentProperties
show database hawkb InconsistentProperties

The InconsistentLogXptProps monitorable property returns a table that shows all properties related to redo transport services whose values are inconsistent between the broker configuration file and the runtime value.

show database hawka InconsistentLogXptProps
show database hawkb InconsistentLogXptProps

The LogXptStatus monitorable property returns a table that contains the error status of redo transport services for each of the enabled configuration members. This property pertains to the primary database, a physical standby database that ships redo data, or a far sync instance.

show database hawka LogXptStatus

The SendQEntries monitorable property returns a table that shows all log files on the primary database that were not successfully archived to one or more standby databases. This property pertains to the primary database

show database hawka SendQEntries

The RecvQEntries monitorable property returns a table indicating all log files that were received by the standby database but have not yet been applied. If no rows are returned, it implies all log files received have been applied. This property pertains to a standby database.

show database hawkb RecvQEntries

The TopWaitEvents monitorable property specifies the 5 events with the longest waiting time in the specified instance.

show instance hawkb1 TopWaitEvents

How to edit database properties for all instances.

edit instance * on database hawka set property logarchivetrace=0;

Lastly, all commands and be run from shell script with example below.

GoldenGate 12.2 TROUBLESHOOTING REPLICAT LAG

Time Since Chkpt and Lag at Chkpt from replicat keep increasing

Program     Status      Group       Lag at Chkpt  Time Since Chkpt
REPLICAT    RUNNING     R_NEW12C    03:49:45      06:37:47    

This occurs for due to the following reasons:

Delivering a long running transaction
Waiting on a full table scan
Blocked by another sessions
Primary extract lag or pump lag keeps increasing

Is There a Way to Make Long-running Transactions Checkpoint? (Doc ID 969684.1)

The tradeoff with GROUPTRANSOPS is with efficiency. 
The tradeoff with MAXTRANSOPS is efficiency and transaction integrity. 

There are no long running transaction from the extract and is monitored using WARNLONGTRANS 15m, CHECKINTERVAL 3m.

grep "Long Running Transaction" dirrpt/E_OLD10G.rpt

My suspicion is FTS, but how to find out?

GoldenGate Debugging

I was working on automating debug information to submit to Oracle Support and thought I share implementation for what was requested.

GoldenGate Extract RBA Not Moving LAG Increasing Appears Hung

OGG Extract RBA Not Moving And LAG Increasing And Appears Hung (Doc ID 964705.1)

Typically, when Goldengate is performing recovery:

In recovery[1] – Extract is recovering to its checkpoint in the transaction log.
In recovery[2] – Extract is recovering from its checkpoint to the end of the trail.
Recovery complete – The recovery is finished, and normal processing will resume.

Example:
Current status: In recovery[1]: Reading from data source

SEND EXTRACT

First time I have seen Processing data with empty data queue and is essentially the same process.

send e* status  
Current status: In recovery[1]: Processing data with empty data queue

send e* status
Current status: Recovery complete: Processing data with empty data queue    

The scary part is current redo vs Goldengate Checkpoint.

To prevent this, make sure there is no lag, no long running transactions before stopping extract.

Basically, NOLOGGING operation occurred from backup before resetlogs recovery
and there is no datafile/database backup following NOLOGGING operations
since database backup is performed once a day.

The Gains and Pains of Nologging Operations (Doc ID 290161.1)

However, NOLOGGING is intended for configurations in which media recovery 
or the recovery of the corresponding object is not important. 
Thus, if the disk or tape or storage media fails, 
you will not be able to recover your changes from the redo because the changes were never logged.

Windows Oracle Services Using PowerShell

Lately, I have been getting feet wet with Windows.
I know GUI can be used but not very good to reproduce.

Here is now to find Stopped Oracle Windows Services and start them.

And if you want to use GUI, run Services.msc from command line.

DBFS and XAG for Goldengate P4

I encountered a situation where I was not able to start dbfs_mount to save my life.

2 people spent over 5 hours and was not able to resolve the issue.

1 person suggested to to restart clusterware because it looks like fuse group was added to oracle after oracle clusterware was up.

During configuration:
kernel-devel was missing, /etc/rc.modules did not exists, oracle was not part of fuse group

# rpm -qa |egrep 'fuse|kernel-devel'
# cat /etc/rc.modules
cat: /etc/rc.modules: No such file or directory
# grep fuse /etc/group
fuse:x:993:

Corrections made:

# cat /etc/rc.modules
/sbin/modprobe fuse

# grep fuse /etc/group
fuse:x:993:oracle

$ crsctl start res dbfs_mount
CRS-2672: Attempting to start 'dbfs_mount' on 'hawk1'
CRS-2672: Attempting to start 'dbfs_mount' on 'hawk2'

CRS-4000: Command Start failed, or completed with errors.

$ crsctl stat res dbfs_mount
NAME=dbfs_mount
TYPE=local_resource
TARGET=ONLINE , ONLINE
STATE=OFFLINE, OFFLINE

After restarting clusterware:

Note: this was started by root which I don't think is a good idea.
# crsctl start resource dbfs_mount
CRS-2672: Attempting to start 'dbfs_mount' on 'hawk1'
CRS-2676: Start of 'dbfs_mount' on 'hawk1' succeeded

Should have been started from grid user
$ crsctl start res dbfs_mount
CRS-2672: Attempting to start 'dbfs_mount' on 'hawk2'
CRS-2672: Attempting to start 'dbfs_mount' on 'hawk1'
CRS-2676: Start of 'dbfs_mount' on 'hawk1' succeeded

$ crsctl stat res dbfs_mount
NAME=dbfs_mount
TYPE=local_resource
TARGET=ONLINE             , ONLINE
STATE=ONLINE on hawk1, ONLINE on hawk2

It really bothered me how this information was missed and where was it documented.

After hours of research, the information is not consistently documented.

To pick up the additional group (fuse) membership for the oracle user on Linux or the workaround above on Solaris, Clusterware must be restarted.
For example, to restart Clusterware on all nodes at the same time (non-rolling), you can use the following commands as root:

DBFS and XAG for Goldengate P3

Start Pump Extract at source failed as shown below.

INFO OGG-00993 Oracle GoldenGate Capture for Oracle, p_test.prm: EXTRACT P_TEST started.
ERROR OGG-01224 Oracle GoldenGate Capture for Oracle, p_test.prm: TCP/IP error 111 (Connection refused), endpoint: ggvip_hawk.local:7809.
ERROR OGG-01668 Oracle GoldenGate Capture for Oracle, p_test.prm: PROCESS ABENDING.

Hypothesis is ports are not opened from source to target and let’s verify configuration.

VIP name and address from DNS.

Name:    ggvip_hawk.local
Address: 10.10.10.201

Recall this is how goldengate instance was created.

# $GRID_HOME/bin/agctl add goldengate gg_xx \
--instance_type target \
--oracle_home /u01/app/oracle/product/12.1.0/db_1 \
--nodes hawk1,hawk2 \
--network 1 --ip 10.10.10.201 \
--user ggsuser --group dba \
--filesystems dbfs_mount \
--gg_home /u03/gg/12.2.0 

From Goldengate instance gg_xx,
Application VIP (gg_xx-vip) is created
using address (10.10.10.201).

Check for xag resource.

ggsuser@hawk1 ~ $ $GRID_HOME/bin/crsctl stat res -t|grep -A2 xag
xag.gg_xx-vip.vip
      1        ONLINE  ONLINE       hawk1                STABLE
xag.gg_xx.goldengate
      1        ONLINE  ONLINE       hawk1                STABLE

Verify Application VIP address assigned.
