I hope you don’t judge a post by its title.

Working with vagrant build and experiencing periodic timed out.

I have probably brought this upon myself since I Create Windows Symlinks to Vagrant Software Folder

However, issue is that it works from GI and not DB software is what agitates me.

Enough of the rant and there is the resolution.

The while loop will repeat the last command until successful.

echo "******************************************************************************"
echo "Unzip database software." `date`
echo "******************************************************************************"

time cp -fv /vagrant_software/${DB_SOFTWARE} ${ORACLE_BASE}
while [ $? -ne 0 ] ; do fc -s ; done
time unzip -oq ${ORACLE_BASE}/${DB_SOFTWARE} -d ${ORACLE_HOME}
while [ $? -ne 0 ] ; do fc -s ; done
time rm -fv ${ORACLE_BASE}/${DB_SOFTWARE}
while [ $? -ne 0 ] ; do fc -s ; done

Somehow, just magically works.

Create Windows Symlinks to Vagrant Software Folder

Filed under: Vagrant,Windows — mdinh @ 12:45 pm

Most Vagrant implementations have some derivative of software folder with file – put_software_here.txt

It does not make sense to have to copy software to the folder and then to delete afterwards repeatedly for every new Vagrant build.

Luckily, there is a way to create symlinks to a centralized software location.

Start vagrant failed – ERROR: gi_software does not exist because software folder was purposely deleted for demo.
Note: Using Git BASH for Windows.

Create symlinks from Windows command line.

C:\Windows\System32>mklink
Creates a symbolic link.

MKLINK [[/D] | [/H] | [/J]] Link Target

        /D      Creates a directory symbolic link.  Default is a file
                symbolic link.
        /H      Creates a hard link instead of a symbolic link.
        /J      Creates a Directory Junction.
        Link    Specifies the new symbolic link name.
        Target  Specifies the path (relative or absolute) that the new link
                refers to.

C:\Windows\System32>mklink /J "G:\oracle\vagrant-boxes\OracleFPP\ORCL_software" "E:\ORCL_software"

Just a crazy idea.
Keep the same backup tag for all backups until the next level 0.

Backup TAG for daily level 0 backup:

[oracle@db-fs-1 ~]$ echo "$(date +%Y%b%d)"
2020Feb19
[oracle@db-fs-1 ~]$

Backup TAG for weekly level 0 backup

[oracle@db-fs-1 ~]$ echo "$(date +%Y%b)_WK$(date +%U)"
2020Feb_WK07
[oracle@db-fs-1 ~]$

Backup TAG for monthly level 0 backup

[oracle@db-fs-1 ~]$ echo "$(date +%Y%b)"
2020Feb
[oracle@db-fs-1 ~]$

Tag: ARCH for archivelog backup and may not be useful.
LV=A means archivelog backup.

In writing this post, I realized the my own backup script will need some improvements.

Note to self for how to easily add user to sudoers file

Filed under: linux — mdinh @ 1:49 pm

Unable to sudo su -:

[grid@ol7-fpp-fpps ~]$ sudo su -

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[sudo] password for grid:
grid is not in the sudoers file.  This incident will be reported.

[grid@ol7-fpp-fpps ~]$ 

Group wheel has ALL privileges:

[root@ol7-fpp-fpps ~]# grep wheel /etc/sudoers
## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL
# %wheel        ALL=(ALL)       NOPASSWD: ALL
[root@ol7-fpp-fpps ~]#

Modify user grid:

[root@ol7-fpp-fpps ~]# usermod -aG wheel grid

Or: usermod -a -G sudo user

Test sudo -:

[grid@ol7-fpp-fpps ~]$ sudo su -
[sudo] password for grid:
