install the gcc-c++4.8.5-39.el7.x86_64.rpm to my test Centos linux box make it to emergency mode, can't start GUI anymore.

anyway to check what  gcc-c++ package has been installed ?

Fourth possibility:  Restore the system using the most recent full backup and never attempt to upgrade gcc again.  This can be enforced using yum and the yum-versionlock plugin.

probably need to destroy it totally !

linux seems very dangerous and unstable ! just once gcc installation can make this happen!

 Ideally there will be something such as "library file version mismatch" which can be corrected.

how to correct ?

Likely what's occurred is you've attempted to place a .rpm on your machine, then install the .rpm directly, rather than through the package repository.

no! I install through CentoS SW store, and it prompt for a restart, and I click yes, then can't start GUI anymore.

all rpm I install manually works well !  except that one from CentOS rps store GUI.

Said another way, some code on your machine is built to only work with the original libc installed + can no longer work with the libc version you have installed now.

you can say it in this way but I just follow what is need for Oracle on linux installattion:

1. https://docs.oracle.com/en/database/oracle/oracle-database/18/ladbi/running-rpm-packages-to-install-oracle-database.html#GUID-BB7C11E3-D385-4A2F-9EAF-75F4F0AACF02
2. https://www.oracle.com/technical-resources/articles/hunter-rac11gr2-iscsi.html#7

The most simple approach will be to remove gcc, leaving dependent software installed, then reinstall the original version of gcc.

in emergency mode I can't run this: cat /var/log/yum.log | grep gcc

it said

cat: /var/log/yum.log: No such file or directory

so you likely have a mess now which can never be fixed.

most likely! and what i did is install that rpm from CentOS application store ! amazing ! I don't like that CentoS linux thing, I downlaod all .rpm from repo of centos and all working fine except this!

but install one application destory everything doesn't make sense.

$ /usr/bin/yum list gcc

'

that linux box is in emergenecy mode, yum said to be missing!~

and I do this:

$ rpm -qa | grep -E -i "^gcc"

nothing returned!

Add following line
export LC_ALL=C
inside /etc/bashrc file.
and re-login at gui.

when I reboot I see that ;

setlocale: LC_ALL: cannot change locale (c): No Such file or directory.

cat ~/.xsession-errors.err

GUI error log ?

yum list gcc-c++
rpm -qa | grep -E -i "^gcc"

I think yum list and rpm -qa do the same thing, to list out what package was installed ?

@marrowyung

I have given my comment only when
>> following error happening: => ~/.xsession-errors.err
Hence remove the changes you have applied in /etc/bashrc

When ever you do changes take a backup

https://gist.github.com/ibrahimlawal/bfec7092cb64d46d8f9d1fd2c0c3d9c8
after testing
if not working
copy backup file to original.

>> to list out what package was installed ?
yes

sample output at my system:

what is 2>&1 for ? combine 2 x result together?

$ yum list gcc-c++ 2>&1 | grep -E -i "^gcc"

I am in emergency mode, can't do yum

This one:  

rpm -qa | grep -E -i "^gcc"

should be

rpm -qa | grep -E -i "gcc"

?

and my result is not that gcc , but libgcc-8.3.1_4.5.e1`8.x86_64

is not that !

what is 2>&1 for ? combine 2 x result together?

David Favor,

The biggest problem that occurs when the compiler + libgcc ends up... out of whack (technical term) is this can cause a cascade of other packages to have been put into odd states... which means you'll have to likely deal with a long parade of problems... fixing one, then many others pop up for each fix...

yeah ! I will remove it then! what i am doing here is learning sth, like what if next I trust a application /package from Centos GUI apps store and install it and it ask for a reboot, then SAME thing happen ?!!?

is this how Centos manage/vaildate an apps ? Windows and ios seems never has this kind of thing! andriod seems also do not have as I don't experience one!

This incident make me do not trust linux at all ! install and apps will have this problem! it should check for conflict and dependence like when we are install using yum /rpm !

amazing !  so next time I experience this agian I have to reinstall everythnig again ?


what I am trying to do is this:

https://www.experts-exchange.com/questions/29173670/procedure-to-install-oracle-on-linux-VM-if-I-have-the-RPM-package.html?anchor=a43064221¬ificationFollowed=249493482&anchorAnswerId=43064221#a43064221

you can try to help on this too ! if it is not this oracle on linux installation execrise I am not going to install that.


MURUGESAN,

rpm -qa | grep -E -i "^gcc"

for me this return nothing.

rpm -qa | grep -E -i "gcc"

this return libgcc-8.3.1-4.5.el8.x86_64

MURUGESAN,

yum -y install gcc-c++

yeah, working for me on other 2 x linux hosts which still fine after reboot

then how to remove it using rpm on the failured nodes?

again, please help on this :

on that nodes, can't do yum as it say yum command not found.

I tried rpm -e <package-name>, it seems can't !

$ sudo rpm -e wget.x86_64

doesn't work for me either.

I think I better reinstall it to save time!

svn is a command ? or you are asking me tto save history to TFS ?

I have used oracle many years ago. Hence cannot provide related help at oracle/mydb.

you mena you havent' touch Oralce on linux for years ?

>> Also save your history using svn/git/TFS, database and SMTP.

We have to save our history using svn command or git command at Linux oriented operating systems.
If they are not available TFS available at windows.
Save your data at Database.
future employee/team => can use them when they need in future => like easy search at bing/google.

All your history commands are saved in $HISTFILE

$ cat $HISTFILE

if TFS svn and git not available => share the content of $HISTFILE file (follow company policies and supervisor approval)

like other than RAC, what oracle is doing better than SQL Server? I see nothing !

era changed  ! RAC is not REAL mulitple write master anyway !  sad ! and RDBMS world experts knows multi concurrent write is not good ! that's why MS SQL Always on also not multi write! MySQL and MariaDB cluster by default is not multi write master! hard to keep ACID is they turn it on !

actually I have post asking how to display real time CPU, RAM, disk and network usage, seems linux do not have it !
