"Failed to start LSB: Bring up/down networking" after OEL 7 VM build

I imported newly built OEL 7.7 VM from Oracle VirtualBox to an ODA (Oracle Database Appliance).

Upon starting up the VM, the network was showing as being up for device "eth0" however the /etc/sysconfig/network-scripts/ifcfg-eth0 was existent at the moment. I restarted the network service but received the "Failed to start LSB: Bring up/down networking" error.

I followed the below steps to resolve this error.


1.  Stop and disable the NetworkManager service.

     # systemctl stop NetworkManager.service
     # systemctl disable NetworkManager.service

2.  Enable the network service.

     # systemctl enable network.service

3.  Create the ifcfg-eth0  and populate with the appropriate information.

     # vi /etc/sysconfig/network-scripts/ifcfg-eth0

contents:
TYPE=Ethernet
BOOTPROTO=static
NAME=eth0
DEVICE=eth0
ONBOOT=yes
IPADDR=<IP_ADDRESS>
NETMASK=<SUBNET_MASK>
GATEWAY=<DEFAULT_GATEWAY>


4.  Restart the network.

     # service network restart

5.  Check to see that the IP address is up and pingable.

     #  ip addr show

[root@localhost ~]# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:16:3e:2a:e4:33 brd ff:ff:ff:ff:ff:ff
    inet 192.168.10.10/24 brd 192.168.10.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::216:3eff:fe2a:e433/64 scope link
       valid_lft forever preferred_lft forever

     #  ping 192.168.10.10


6.  Remove any other miscellaneous ifcfg-e* files

     #  cd /etc/sysconfig/network-scripts    
     #  rm ifcfg-enp0s3

RMAN-10038: database session for channel prm3 terminated unexpectedly

Problem: I had an issue where I was trying to build a 1.7 TB Data Guard environment and kept receiving the highlighted error below.  I thought it was some type of fluke so I restarted the job 2 more times only to receive the same error. Fix: After researching the issue, I found it was because the sqlnet.ora needed to be configured correctly.  I added the entry " SQLNET.EXPIRE_TIME = 10 " to the sqlnet.ora on both the source and the target database servers under the RDBMS $ORACLE_HOME/network/admin.  Upon restarting the RMAN active database standby build, it was able to move past this error and built successfully.

ORA-17630: Mismatch in the remote file protocol version client 2 server 3

I was trying to create an Oracle Data Guard environment (physical standby) from an Oracle database running version 12.1.0.2. The database was running an older PSU version ("Database Patch Set Update : 12.1.0.2.161018 (24006101)") to be specific. Upon trying to build the standby by using RMAN DUPLICATE with ACTIVE DATABASE, I ran into the below error: executing Memory Script Starting backup at 16-JUL-18 RMAN-03009: failure of backup command on prm1 channel at 07/16/2018 13:51:46 ORA-17629: Cannot connect to the remote database server ORA-17630: Mismatch in the remote file protocol version client 2 server 3 continuing other job steps, job failed will not be re-run released channel: prm1 released channel: prm2 released channel: prm3 released channel: prm4 released channel: prm5 released channel: stb1 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: ====================

ORA-00338: log {n} of thread {n} is more recent than control file

I received the following error in a primary database's alert log that I was supporting recently.   ORA-00312: online log 5 thread 1: '+DATA/db_name/onlinelog/group_5.297.846947859' ORA-00338: log 5 of thread 1 is more recent than control file The database has a DataGuard environment as well and below are the steps that I took to resolve the issue. 1.  First, I checked the status of the redo logs and their current sizes and status. SQL> select group#,bytes/1024/1024,status from v$log;     GROUP# BYTES/1024/1024 STATUS ---------- --------------- ----------------          1              50 INACTIVE          2              50 INACTIVE          3              50 INACTIVE          4             250 INACTIVE          5             250 INACTIVE          6             250 CURRENT 2.  As you can see, groups 1, 2, 3 have 50 MB redo log group sizes while group 4, 5, 6 are 250 MB redo log group sizes.  This is something that I highly suspect was/is the issue.  So I
