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...

WGET Syntax for downloading patches from Metalink

-
I am sure everyone knows this but just to emphasise the point (and ease the pain somewhat), Classic MetaLink Retires November 6, 2009.

Extract of the text of email from Oracle Support:

During the weekend of November 6 – 8, 2009, My Oracle Support, Oracle's next-generation customer support platform, will be upgraded and Classic MetaLink will be retired.

Moreover (and this is the most painful part especially for Apps DBAs), the ftp to the patch site will also retire on 06-Nov-2009. :(

Below is the extract of the message displayed on updates.oracle.com ftp site:

230-  This service will be retired on November 06, 2009 and "My  Oracle Support"
230-  will be the only interface for downloading the patches and updates. To
230-  search and download patches from "My Oracle Support" users are required
230-  to login to https://metalink.oracle.com and then go to "Patches & Updates"
230-  tab.

Though I do NOT like it, I suppose I have to force myself to use wget to download patches directly on to the server, instead of downloading them to my local machine and then transferring them to the server (a much more painful process).

So, as a heads up, I would like to share with you the syntax for using wget.

Note: The below syntax worked for Solaris 10 and might not work for other flavours of UNIX since the default installation directory may be different. 




/usr/sfw/bin/wget --http-user=<Metalink Username> --http-passwd=<Metalink Password> --output-document=<Name of patch>
"<URL>"

1. Get the URL in the following way:

a. Login to metalink and query up the patch.
b. Right click on the download button and click on "Copy Shortcut" (IE).

2. The name of the patch would be a subset of the URL.


eg:

/usr/sfw/bin/wget --http-user=<Metalink Username> --http-passwd=<Metalink Password> --output-document=p8618053_11i_GENERIC.zip  "http://updates.oracle.com/ARULink/Download/process_form/p8618053_11i_GENERIC.zip?file_id=27640717&aru=11477117&userid=ml-693674.993&email=praveen.krishnamurthy@qwest.com&patch_password=&patch_file=p8618053_11i_GENERIC.zip"


Hope this is helpful in the painful transition from the updates.oracle.com ftp site to the Flash Player based new and "improved" Metalink.

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              ...

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; / References: Metalink (MOS) Note ID: 261693.1 FND_FILE set serveroutput on exec FND_FILE.PUT_LINE(FND_FILE.LOG, 'THIS IS A TEST'); HTH....
