Stop the cluster 

==============
Stop the cluster
#> pcs cluster stop --all

Tag and enable 

#> for i in $(vgscan |grep Ora | cut -d '"' -f 2) ;do vgchange --addtag sometag $i ; vgchange -ay --config 'activation{volume_list=["@sometag"]}' $i ; done

Mount locally

Stop Cluster

hastop -all 

or

hastop -all -force

Perioticly check cluster status until it is unavailable - like the following message:

hastatus -summary

VCS WARNING V-16-1-11046 Local system not available

or freeze just the oracle group

hagrp -freez ora_igt_sg

Mount locally the oracle mount points

vxdg import OraDg1

vxdg import OraDg2

vxdg import OraDg3

vxvol -g OraDg1 startall

vxvol -g OraDg2 startall

vxvol -g OraDg3 startall

mount -t vxfs /dev/vx/dsk/OraDg1/db1        /oracle_db/db1

mount -t vxfs /dev/vx/dsk/OraDg3/db2        /oracle_db/db2

df -hP | grep ora

Do the Oracle stuff

Dismount locally the oracle mount points

umount /oracle_db/db1 

umount /backup/ora_online

umount /backup/ora_exp

umount /oracle_db/db2

Start the service

Run the following command on ALL cluster nodes:

node a

hastart

node b

hastart

Additional Commands

===========

move service to another node

as root

pcs status

pcs resource cleanup ora_igt_rg

pcs resource disable ora_igt_rg

pcs resource enable ora_igt_rg

pcs resouce show ora_igt_rg

To create a service

as root Check on oracle service definition

/etc/sysconfig/env.oracledb 

for oracle service - check this file:

/etc/systemd/system/dbora.service

This defines the oracle service, ORACLE_HOME, ORACLE_SID

/etc/sysconfig/evn.oracledb

run this:

systemctl status dbora

systemctl status dbora.service

systemctl start dbora.service

systemctl deamon

pcs resource create dbora_igt_ap systemd:dbora op stop interval=0 timeout=120s on-fail="block" monitor interval=30s timeout=600s start interval=0 timeout=120s --group ora_igt_rg

pacemaker cluster commands info

pcs status - this will show cluster status

pcs resource show - this will show current node status

pcs resource show dbora_igt_ap - this will show oracle service info

 Resource: dbora_igt_ap (class=systemd type=dbora)

  Operations: monitor interval=30s timeout=600s (dbora_igt_ap-monitor-interval-30s)

              start interval=0 timeout=120s (dbora_igt_ap-start-interval-0)

              stop interval=0 on-fail=block timeout=120s (dbora_igt_ap-stop-interval-0)

Check corosync in short

root>% vi /etc/corosync/corosync.conf 

root>% pcs cluster sync

server901G: Succeeded

server902G: Succeeded

root>% pcs cluster reload corosync

Corosync reloaded

root>% corosync-cmapctl | grep totem.token

runtime.config.totem.token (u32) = 5000

runtime.config.totem.token_retransmit (u32) = 1190

runtime.config.totem.token_retransmits_before_loss_const (u32) = 4

totem.token (u32) = 5000

Change corosync timeout

1. Edit /etc/corosync/corosync.conf on one of the cluster nodes

Add the required line if does not exist or update the value if the line does exist.

For 5 seconds, set the value to 5000 msec.

totem {

   version: 2

   secauth: off

   cluster_name: rhel7-cluster

   transport: udpu

   rrp_mode: passive

   token: 15000      <--- If this line is missing, add it, otherwise update the value.-->

}

2. Propagate the updated corosync.conf to the rest of the nodes as follows:

pcs cluster sync

3. Reload corosync.
    This command can be run from one node to reload corosync on all nodes and does not require a downtime.

pcs cluster reload corosync

4. Confirm changes

corosync-cmapctl | grep totem.token

For example:

corosync-cmapctl | grep totem.token

runtime.config.totem.token (u32) = 5000

runtime.config.totem.token_retransmit (u32) = 1190

runtime.config.totem.token_retransmits_before_loss_const (u32) = 4

User Permissions SQL Server

db_owner
Members of the  fixed database role can perform all configuration and maintenance activities on the database, and can also drop the database in SQL Server. 
db_datawriter
Members of the db_datawriter fixed database role can add, delete, or change data in all user tables.
db_ddladmin
Members of the db_ddladmin fixed database role can run any Data Definition Language (DDL) command in a database.

To change User permissions:

Database -> Security -> Users -> Properties -> membership -> add use to the required group

Rename files in SQL Server

USE [master];
GO
--Disconnect all existing session.
ALTER DATABASE jiradev4 SET SINGLE_USER WITH ROLLBACK IMMEDIATE
GO

--Change database in to OFFLINE mode.
ALTER DATABASE jiradev4 SET OFFLINE
GO

ALTER DATABASE jiradev4 MODIFY FILE (Name='jiradev4', FILENAME='D:\DB\jiradev4.mdf')
GO

ALTER DATABASE jiradev4 MODIFY FILE (Name='jiradev4_log', FILENAME='D:\Logs\jiradev4_log.ldf')
GO

Here - physically rename datafiles on server to the new names

ALTER DATABASE jiradev4 SET ONLINE
Go
ALTER DATABASE jiradev4 SET MULTI_USER
Go

Refresh the databases list, and check the database properties.

SQL Server Copy Database options

Need to copy database from databaseName=dba_util to dba_util_test.

In SQL Server, several options to do that.

Option 1 – Using Backup and Restore

Backup
1.      Right click on the database you want to duplicate and choose Tasks->"Back Up..."
2.     Save the back up to a .bak file

Important - When doing export: go to tab Media Options -> select "Overwrite all existing backup sets"

Restore

1.      Right click on the "Databases" ->  "Restore Database"
2.      As the source, select "File" and point to the .bak file you created earlier.
3.      Change the name of the database to restore to.

Important:  When doing import: go to tab Options -> Uncheck "Tail-long Backup"

It will make the restore much faster, and to the point of time the backup was taken.

Option 2 – using Database Copy Wizard
Database -> my_database -> Tasks -> Copy ->
Source server MY_SERVER->
Destination Server MY_SERVER->
Select option Detach + Attach (source database must be offline, faster) or "SQL Management Option" (source database can be online, slower) ->
Select database Name to copy ->
Give new Database Name -> my_database_new
Give new Database File path  D:\DB
Give new Database Log path D:\Logs ->
A new package is created under server_name/DTS Packages/Copy Database Wizard Packages CDW_MY_SERVER_dba_util_copy ->
Run Immediately ->

 

Click Finish to perform the following actions:

 Source: MY_SERVER Other SQL Server Version, Microsoft SQL Server Standard Edition (64-bit) , Build 3223, Microsoft Windows NT 6.3 (14393) NT x64

Destination: MY_SERVER Other SQL Server Version, Microsoft SQL Server Standard Edition (64-bit) , Build 3223, Microsoft Windows NT 6.3 (14393) NT x64

Using SMO online transfer

The following databases will be moved or copied:

 

Copy:dba_util

Destination file will be created: D:\DB\dba_util_test.mdf

Destination file will be created: D:\Logs\dba_util_test_log.ldf

Stop transfer if duplicate database name exists at destination

 

Package scheduled to run immediately

=====================

OPTIONS(DIRECT=TRUE)

=====================

By default, direct load is not activated in sqlldr, and the load is via regular flow.

To avoid archiving during load, one can activate direct load by:

A. set table to be NOLOGGING

B. add OPTIONS(DIRECT=TRUE) to sqlldr control file

This will cause a direct path load, and when sqlldr is running, this message with appear:

Path used:      Direct

For example:

OPTIONS(DIRECT=true)
