[GENERAL] PostgreSQL to Oracle
Hi All, I want to migrate from PostgreSQL to Oracle and need any tool preferably open source. And I am specially concerned with stored procedures / functions. Regards, Abdul Rehman.
[GENERAL] Oracle Functions to PostgreSQL
Hi all, Is there any preferably open source tool to convert Oracle Functions to PostgreSQL Functions. Thanks, Abdul Rehman.
Re: [GENERAL] Download link for 'Bristlecone'
Thanks Huxton & Gerd; I think pgbench is not suitable for those who want to test application on desired tables. pgbench is highly hard coded and tests only self generated tables. I used Mercury LoadRunner but it is not freeware. The link http://bristlecone.continuent.org/HomePage only has details about this software but not the download link. Secondly it is for Unix not for Windows. And I found AppLoader freeware but it does not include PostgreSQL in its database list. My research is ongoiung and will prompt you as I get something fruitful and expecting the same from you. Regards, Abdul Rehman.

Sorry - never heard of Bristlecone. You might want to start with "pgbench" which is in the contrib/ directory of the source distribution: http://www.postgresql.org/docs/current/static/pgbench.html Make sure you read the manual page above, and also search the mailing-list archives for tips on how to get useful information from it. You might also be interested in the sourceforge DBT project http://sourceforge.net/projects/osdldbt/ Read this msg first though, there is more up-to-date code available than the sf.net download page. http://archives.postgresql.org/pdxpug/2008-12/msg00010.php Really though, unless you're doing this as part of an academic paper you'll want to write your own test cases. It doesn't matter whether PostgreSQL is fast or slow on the tests above, what matters is how it performs *for your purposes*. The only way to test that is to generate the sort of data and workload that you plan to have. Oh, and it's very easy to end up with data that tells you nothing useful. Make sure your tests are long enough, and that they're not too sensitive to minor changes in configuration or load. HTH -- Richard Huxton Archonet Ltd
Re: [GENERAL] Appending \o output instead of overwriting the output file
Simply use '\o filename' as you are doing so. Write the queries as much as you want. It will automatically append the result in the specified file. Untill you use '\o' command again with new file name.

Kindly let me know two things to answer you. First, Are you trying to start postgres service or psql prompt? second, what OS is in your use.
Re: [GENERAL] Multiple postgres.exe On Processes
Dear All, Thanks John R Pierce for replying fruitful text. I wold like to add some text in your reply from PostgreSQL document for further clarification. i.e. Each connection runs one process, plus the 3 master processes for the postmaster, the writer, etc. with two logins, I'd expect to see 5 processes. with 102 concurrent logins, 105 processes.[From Pierce] The PostgreSQL server can handle multiple concurrent connections from clients. For that purpose it starts (“forks”) a new process for each connection. From that point on, the client and the new server process communicate without intervention by the original postgres process. Thus, the master server process is always running, waiting for client connections, whereas client and associated server processes come and go.[From PostgreSQL Document] Thanks all. Regards, Abdul Rehman
[GENERAL] Multiple postgres.exe On Processes
Dear All, I have fear that sufficient increase in number of postgres.exe after one or two logins on servers may down the speed of the server or even server. Is there any solution or technique to overcome this overhead. Regards, Abdul Rehman.
Re: [GENERAL] Key Vs Index
I have found the answer. PostgreSQL creates index on primary key implicitly and can be seen via \d tablename; command on psql prompt. But PG_Admin-III does not show this index. Sorry to say that I faced several problems because of PG_Admin-III. And I advise you to use psql prompt instead of GUI. From: Abdul Rahman To: pgsql-general@postgresql.org Sent: Wednesday, February 11, 2009 12:09:25 PM Subject: Key Vs Index In Oracle, the index is automatically created during the creation of Primary Key. But in PostgreSQL either index is implicitly created of the user hast create it explicitly. I don't find any index against Primary Key and have to create index on this key.

Re: [GENERAL] Rollback of Query Cancellation
Well Jaime, I executed all the delete queries one by one. Now I am unable to understand that why it took sufficient time to run the last query before cancellation. i.e. delete from ci_cif_v where req_id='0824100207'; This morning it performed the delete operation and deleted certain number of rows within few seconds. Then what it was doing yesterday. Here it seems that it was performing something else (as guessed by Sim Zacks) before the execution of delete query. And when I canceled, the query was not executed till that time. Then why it didn't take sufficient amount of time to perform something else before the execution of same query today.

Re: [GENERAL] Rollback of Query Cancellation
Very nice! Most probably it was waiting for something else. This is the reason the query executed today and clearly showed certain number of rows deleted. But what ELSE?

Dear All, Yesterday I canceled a running query because it was taking long time (more than 12 minutes) to delete lots of records.

Re: [GENERAL] [ADMIN] PgAgent Job Scehduler is NOT running
Thanks Vishal, I followed the document and now the statistics of the job is appearing and showing successful but actually backup is not made via this job. In output tab it gives the following error: could not open the file "D:\xxx.backup":Permission denied. I tried to perform the task from both (normal & postgres) users of OS. But no benefit.

Re: [GENERAL] Scheduling backup via PgAgent
Oh! I have got the mistake made by me. Actually I didn't start the PostgreSQL Scheduling Agent - pgAgent service. Now its working fine. I also have attached the complete document of my work for the sake of knowledge share. Regards, Abdul Rehman.
[GENERAL] Scheduling backup via PgAgent
Dear all, After installing PgAgent I have successfully created a job for auto scheduled backup. But it is not working. I have tried both method i.e. via .bat and via SQL. Kindly guide me and give chance to pay thanks. Regards, Abdul Rehman
Re: [GENERAL] Replication with slony-I
TOO MANY THANKS RAY! I have got success in doing replication to an existing database. I did test on a dummy databases. But I am sure that I can implement to live project. Regards, Abdul Rehman.
Re: [GENERAL] Replication with slony-I
The detail of my work is as under: As I mentioned earlier that platform is windows xp and using postgres 8.2 in which Slony- I is included. And all databases are at localhost. After reading the document entitled “Replicating Your First Database” which is for Linux I optimized the instructions for windows and performed the following tasks: I didn’t find any line like tcpip_socket=true in my postgresql.conf. Because there is another option and i.e. listen_addresses = '*'. I changed it to listen_addresses = 'localhost'. In pg_hba.conf, I changed the line host all all 127.0.0.1/32 md5 To host all all 127.0.0.1/32 trust Then created 2 databases named: master and slave Executed the command pgbench -i -s 1 -U $PGBENCHUSER -h $MASTERHOST $MASTERDBNAME After optimizing it i.e.: pgbench -i -s 1 -U postgres -h localhost master Slony-I does not automatically copy table definitions from a master when a slave subscribes to it, so we need to import this data. I did this with pg_dump. pg_dump -s -U postgres -h localhost master > schema.sql psql -U postgres -h localhost slave < schema.sql Executed the command: pgbench -s 1 -c 5 -t 1000 -U postgres -h localhost master Optimized the given script (and used slonik to run this) as follows: cluster name = pgbench; node 1 admin conninfo = 'dbname=master host=localhost user=postgres'; node 2 admin conninfo = 'dbname=slave host=localhost user=postgres'; init cluster ( id=1, comment = 'Master Node'); table add key (node id = 1, fully qualified name = 'public.history'); create set (id=1, origin=1, comment='All pgbench tables'); set add table (set id=1, origin=1, id=1, fully qualified name = 'public.accounts', comment='accounts table'); set add table (set id=1, origin=1, id=2, fully qualified name = 'public.branches', comment='branches table'); set add table (set id=1, origin=1, id=3, fully qualified name = 'public.tellers', comment='tellers table'); set add table (set id=1, origin=1, id=4, fully qualified name = 'public.history', comment='history table', key = serial); store node (id=2, comment = 'Slave node'); store path (server = 1, client = 2, conninfo='dbname=master host=localhost user=postgres'); store path (server = 2, client = 1, conninfo='dbname=slave host=localhost user=postgres'); store listen (origin=1, provider = 1, receiver =2); store listen (origin=2, provider = 2, receiver =1); On MASTERHOST (localhost) the command to start the replication executed the command: slon pgbench "dbname=master user=postgres host=localhost" On SLAVEHOST (localhost) the command to start the replication executed the command: slon pgbench "dbname=slave user=postgres host=localhost" To start replicating the 4 pgbench tables (set 1) from the master (node id 1) the the slave (node id 2), executed the following script: cluster name = pgbench; node 1 admin conninfo = 'dbname=master host=localhost user=postgres'; node 2 admin conninfo = 'dbname=slave host=localhost user=postgres'; subscribe set ( id = 1, provider = 1, receiver = 2, forward = no); Got SUCCESS up to this point. Now I think this is pgbench which is responsible for replicating tables. Now my question is that how to include the tables which are already present in an existing database
Re: [GENERAL] Replication with slony-I
Ok Ray! I will send the detail of my work soon. Thanks to All participants.
Re: [GENERAL] Replication with slony-I
The link of the document, entitled "Replicating Your First Database" is as under: http://slony1.projects.postgresql.org/slony1-1.2.6/doc/adminguide/firstdb.html
Re: [GENERAL] Replication with slony-I
I followed the document entitled entitled "Replicating your first database" and got SUCCESS In implementing the given example. But, the implementation on existing database is not working for the tables already exists in the database. The replication is being only among four tables created via pgbench tool (accounts, history, branches, tellers). whats going on! --- On Tue, 10/28/08, Abdul Rahman <[EMAIL PROTECTED]> wrote: From: Abdul Rahman <[EMAIL PROTECTED]> Subject: Re: [GENERAL] Replication with slony-I To: [EMAIL PROTECTED] Cc: pgsql-general@postgresql.org Date: Tuesday, October 28, 2008, 9:05 AM Thanks a lot Ray!

There's a pretty good step-by-step guide in the Slony documentation - I haven't it to hand, but it's entitled "Replicating your first database" or something like that. As I recall, it's based on a *nix setup, but Windows is mentioned too. Off the top of my head, the only major difference is that instead of running a separate slon daemon for each node, on Windows you run a single slon as a service, and then invoke it with "/addengine" for each node...it's all in the docs.

May any one support step by step procedure for the replication with slony-I in windows xp.
Re: [GENERAL] Replication using slony-I
Dear all, Due to personal reason (to celebrate EID) I will rejoin my work from 06-Oct-2008. Regards, Abdul Rehman
Re: [GENERAL] Replication using slony-I
How will I get know that all slons are running? However in the replication "pgbench" properties the value of Slon PID is Not Running in each node. Yes, every node is listed with its path and listen. And what do you mean by "do you see the connections on each node".
