Now to resolve error failchk DB_RUNRECOVERY Fatal error run database recovery

When trying to install an application through yum [Yellowdog Updater, Modified] You may get an error message saying from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery

error message is shown below.

root@server [/home]# yum install appname
rpmdb: Thread/process 920761/140379164112640 failed: Thread died in Berkeley DB library
error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db3 -  (-30974)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed

What should we do now, its simple, You first try clearing the yum repository as below.

root@server [/home]# yum clean
rpmdb: Thread/process 920761/140379164112640 failed: Thread died in Berkeley DB library
error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db3 -  (-30974)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed

You were still shown the error message as above, You will need to rebuild the rpm database.

Try the command rpm –rebuilddb

root@server [/var/lib/rpm]# rpm --rebuilddb
rpmdb: Thread/process 920761/140379164112640 failed: Thread died in Berkeley DB library
error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db3 -  (-30974)

You will get the error message as below.

Before rebuilding, we have to first remove the existing __db. files or move it somewhere.

change the director to /var/lib/rpm where the rpm details are stored.

root@server [/home]# cd /var/lib/rpm
root@server [/var/lib/rpm]# ll -h

You see on the above command result, __db.001, __db.003 and etc.. this are the files that needs to rebuilt.

Now for safetyI created a folder named ddb and moved the files to it.

root@server [/var/lib/rpm]# mkdir ddb
root@server [/var/lib/rpm]# mv _* ddb/

After moving the files,
Use the command rpm –rebuilddb

root@server [/var/lib/rpm]# rpm --rebuilddb

Before we start installing any packages, we need to clean the rpm repository

root@server [/var/lib/rpm]# yum clean all
Loaded plugins: fastestmirror, rhnplugin, security
Cleaning repos: base cl-mysql-meta cloudlinux-x86_64-server-6 extras updates
Cleaning up Everything
Cleaning up list of fastest mirrors

You can now able to install application using yum without any issues.

root@server [/var/lib/rpm]# yum install appname

That is all, this help you in resolving the yum db corrupt issue
