Azure: yum install returns [Errno 14] curl#58 – “SSL peer rejected your certificate as expired.”

November 27, 2018 1 Comment

Action:

I have deleted tigervnc rpm and was trying to reinstall it but got the following error:

yum install tigervnc*

https://rhui-3.microsoft.com...x86_64/dotnet/1/debug/repodata/repomd.xml: [Errno 14] curl#58 - "SSL peer rejected your certificate as expired."
Trying other mirror.

Actually, the problem is not related to tigervnc only, it is global. During this time I was not able to run yum update or any installation using yum.

Causes:

Red Hat Update Infrastructure (RHUI) certificate has expired and it needs to be updated.

Solution:

Update RHUI certificate using the following rpm:

For RHEL 7:

# curl -o azureclient.rpm https://rhui-1.microsoft.com/pulp/repos/microsoft-azure-rhel7/rhui-azure-rhel7-2.2-74.noarch.rpm
# sudo rpm -U azureclient.rpm

For RHEL 6:

# curl -o azureclient.rpm https://rhui-1.microsoft.com/pulp/repos/microsoft-azure-rhel6/rhui-azure-rhel6-2.2-74.noarch.rpm
# sudo rpm -U azureclient.rpm

ORA-17635: failure in obtaining physical sector size for ‘+DATA’

November 4, 2018 Leave a comment

Action:

I was trying to create a spfile on asm diskgroup from standby database.

SYS @ shcat > create spfile='+DATA' from pfile='/tmp/initshcat_stby.ora';
create spfile='+DATA' from pfile='/tmp/initshcat_stby.ora'
*
ERROR at line 1:
ORA-17635: failure in obtaining physical sector size for '+DATA'
ORA-12547: TNS:lost contact
ORA-12547: TNS:lost contact

Troubleshooting:

I’ve checked the sector size and it was ok:

SQL> select name,sector_size from v$asm_diskgroup;

NAME       SECTOR_SIZE
---------- ------------
DATA       512

I’ve checked if oracle account was able to see ASM diskgroups in DBCA and it was not. The diskgroup list was empty.

Causes:

There are several causes:

1) File permissions in <Grid_home>/bin/oracle executable not set properly.

2) Oracle user is not a part of asmdba group

Solution: 

1)  Change permissions:

[root@stbycat ~]# chmod 6751 /u01/app/18.3.0/grid/bin/oracle

2)  Add oracle to asmdba group

[root@stbycat ~]# usermod -g oinstall -G oper,dba,asmdba oracle

In my case it was 1st.

My permissions:

$ ll /u01/app/18.3.0/grid/bin/oracle
-rwxr-x--x 1 grid oinstall 413844056 Nov 4 09:14 /u01/app/18.3.0/grid/bin/oracle

Must be:

$ ll /u01/app/18.3.0/grid/bin/oracle
-rwsr-s--x 1 grid oinstall 413844056 Nov 4 08:45 /u01/app/18.3.0/grid/bin/oracle
