Sometimes i have to recreate a table on the oracle standby database to keep standby consistent with the primary. It can be performed by DBMS_LOGSTDBY.INSTANTIATE_TABLE procedure. This procedure uses three parameters. These parameters are “Schema Name”, “Table Name”, “DB Link”.

I created a dblink that connected primary database with the user.
create database link stdb_to_prm connect to <schema> identified by <password> using '<TNS NAME>';

Then instantiated the table. (Remember STANDBY SQL APPLY is stopped.)

When i first made this process, i got following error:

ORA-16279: Supplied dblink must have CONNECT, RESOURCE, and SELECT_CATALOG_ROLE roles
ORA-06512: at “SYS.DBMS_INTERNAL_LOGSTDBY”, line 5359
ORA-00942: table or view does not exist.

As mentioned in the error code, i gave the appropriate privileges to the user on the primary database.

But it still gave the same error. I checked the privileges that i gave the user.
select GRANTED_ROLE from dba_role_privs where GRANTEE=<user>;

Why was it giving same error? While i was struggling, i tried to drop dblink and recreate it. That’s it. Problem solved. It is understood that in the process of instantiation of a table, reqiured roles must be given before creating the dblink.


  1. The schema_name used in creation of DB link...should be given with these previs.

Creating Multiple VLANs over Bonding Interfaces with Proper Routing on a Centos Linux Host

In this post, I am going to explain configuring multiple VLANs on a bond interface. First and foremost, I would like to describe the environment and give details of the infrastructure. The server has 4 Ethernet links to a layer 3 switch with names: enp3s0f0, enp3s0f1, enp4s0f0, enp4s0f1 There are two bond interfaces both configured as active-backup bond0, bond1 enp4s0f0 and enp4s0f1 interfaces are bonded as bond0. Bond0 is for making ssh connections and management only so corresponding switch ports are not configured in trunk mode. enp3s0f0 and enp3s0f1 interfaces are bonded as bond1. Bond1 is for data and corresponding switch ports are configured in trunk mode. Bond0 is the default gateway for the server and has IP address Bond1 has three subinterfaces with VLAN 4, 36, 41. IP addresses are,, respectively. Proper communication with other servers on the network we should use routing tables. There are three

3 Node (Master Slave Slave) Redis Cluster with Sentinel

It is possible to make your Redis cluster Fault Tolerant and Highly Available by building a replica set and then monitor these nodes using sentinel for automatic failover. I am going to give an example setup to explain it. The structure is built with three nodes running one as a master and two as slaves. Master Node: (Centos 7.2) Slave1 Node: (Centos 7.2) Slave2 Node: (Centos 7.2) Edit System settings on each node: /etc/sysctl.conf Disable transparent hugepage (transparent_hugepage=never) on each node: /etc/default/grub Apply grub config and reboot each node: Master Node: /etc/redis/6379.conf Slave1 Node: /etc/redis/6379.conf Slave2 Node: /etc/redis/6379.conf Master Node: /etc/redis/sentinel.conf Slave1 Node: /etc/redis/sentinel.conf Slave2 Node: /etc/redis/sentinel.conf Each Node: /etc/systemd/system/ Each Node: /etc/
