Redis user permissions (ACL) and python connection

-
 Recently, I was working on setting up a redis cluster along with separate users for readwrite and readonly. I setup the readonly user using the below privileges (ACLs):   user redisreadonly on >mySuperSecretPassword ~* resetchannels -@all +@read +ping +asking   Once this is setup, I wrote a simple program in python to connect to the redis cluster using the readonly credentials and print the number of keys.   #!/usr/bin/env python3 """ pip3 install redis """ from redis.cluster import RedisCluster, ClusterNode # ─────── Cluster connection ─────── startup_nodes = [ ClusterNode("redis_host_1", 6379), ClusterNode("redis_host_2", 6379), ClusterNode("redis_host_3", 6379) ] rc = RedisCluster(startup_nodes=startup_nodes,decode_responses=True,username='redisreadonly',password='mySuperSecretPassw...

Check if UTL_FILE and FND_FILE are working fine

-
Yesterday, while troubleshooting a vexing ORA-29280 error, I came across 2 useful PL/SQL anonymous blocks that can be used to test FND_FILE and UTL_FILE to find out whether they are indeed working fine.


UTL_FILE
set serveroutput on 
DECLARE 
  file_location VARCHAR2(256) := '<first entry on utl_file_dir>'; 
  file_name VARCHAR2(256) := 'utlfile1.lst'; 
  file_text VARCHAR2(256) := 'THIS IS A TEST'; 
  file_id UTL_FILE.file_type; 
BEGIN 
  file_id := UTL_FILE.fopen(file_Location, file_name, 'W'); 
  UTL_FILE.put_line(file_id, file_text); 
  UTL_FILE.fclose(file_id); 
EXCEPTION 
  WHEN UTL_FILE.INVALID_PATH 
  THEN dbms_output.put_line('Invalid path ' || SQLERRM); 
    WHEN OTHERS 
  THEN dbms_output.put_line('Others '|| SQLCODE || ' ' || SQLERRM); 
END; 
/

FND_FILE
set serveroutput on
exec FND_FILE.PUT_LINE(FND_FILE.LOG, 'THIS IS A TEST');

HTH.

Interesting Oracle Applications (EBS) Interview Questions

-
Below are some interesting interview questions that I have faced over the years. What is the difference between a concurrent manager and a cron job? Can one patch a CRS Oracle home with the CRS services up? Suppose, there are 2 nodes node1 and node2 with CRS cluster and one wants to patch node1. Can it be done with node2 being up? Suppose one fires a select statement and the data does not in the library cache, then the data, obviously, has to be fetched from the data files. Which background process is used for this purpose? What are the sizing requirements for say, a 100 concurrent users Oracle Apps Installation? What is the difference between a shared appl_top and a staged appl_top?

Modify retention period of workflow queues

-
Yesterday, there was a requirement to increase the retention period of WF_DEFERRED and WF_BPEL_Q so that the developers could troubleshoot issues involving business events. This can be done this way: 1. Check the retention period of existing workqueues. SQL> SELECT owner, name, retention FROM all_queues WHERE name LIKE 'WF%'; OWNER           NAME                                                RETENTION --------------- --------------------------------------------- ------------------------------ APPS                 WF_BPEL_Q                                                0 APPLSYS         WF_INBOUND_QUEUE              ...
