When the COBOL program mapped to a DB2 user defined function, in one of our apps is triggered. It fails with the SQLCODE = -927 & SQLSTATE=51006. There is explanation that Language interface was called without establishing connecting environment. But can someone please advise how to solve this.
Should I be using any specific compiler options or bind parameters while compiling the above mentioned COBOL program which gets triggered by DB2 function.
It seems your batch components includes JCL and Cobol + DB2 and you are trying to execute the Cobol program in the job like PGM = Cobol program name but since your are executing a DB2 component, you need to execute the program via utility like IKJEFT01 and it will solve your problem.

I have a generic question (not an issue). I am trying to run a big query with (lot of join conditions connecting 15-20 tables). Do we have any limitations in ibm_db while running big queries ? The query has been running in our production environment for more than 15 years. I am able to run the query in a in-home .Net tool. However, while running it using ibm-db in pycharm I keep getting sqlcode -905 resource limitation error. Is there anything I am missing with ibm-db usage ?
Any insight will be helpful. Thank you for the help.
Most likely this -905 sqlcode has nothing to do with python or ibm_db.
Instead, it is more likely due to how the workload/resource management is configured at the Db2 server. Your question gave zero facts about the target Db2 environment, or about the difference(s) between the execution that works (.net) versus the execution that triggers the limitation.
One specific detail to eliminate is that the account (auth-id) used for the .net application might be different to the account you use when connecting from python. The Db2-server may be configured to allocate based on User-Id (auth-ID) , or other client side factor (depending on the Db2-server platform and version).
You can prove that the -905 symptom has nothing to do with python or ibm_db by temporary eliminating both, for example by submitting the same query from the db2cli tool (or db2 clp if your client workstation has it), or by submitting the query from jdbc (as long as you use the same account name for connecting as you do with python).
Contact your DBA team for details of the configuration of the WLM or RLF or whatever resource management tooling is deployed at the target Db2 subsystem. In addition, use python ibm_db to print out the full details of the exception (including the resource name, limit amount1/2, limit source, as they can also yield more information).
Is there a way to run a Firebird stored procedure at specific time from the server itself ? something like a schedule task service in SQL Server.
There is no builtin scheduler in Firebird. But it should be relatively easy to set up a task in system scheduler which uses isql to execute an sql script which does what you want.
No it's not possible internally. You should use a third party tool.
Please take a look at this issue
I'm new to AS400 DB2 , I have 3 procedures in AS400, now those procedure should be execute by calling single job in AS400.
Can you tell me please how to create a job and execute job in AS400 DB2 Mainframe ?
You're probably not using an AS/400 running OS/400; they have been obsolete for 10 years. You're probably using a POWER server running IBM i.
POWER servers are not mainframes, they are mid-range systems.
On the IBM i, a job is how the operating system organizes, tracks, and processes work. On other platforms, you'd call it a process.
Jobs are the basis of work management
When you sign onto a 5250 session, the system starts an "interactive job" to service your requests. You can't call procedures directly, but you can call a program that then calls the procedures.
There are plenty of common jobs tasks. Including the use of Submit Job (SBMJOB) command to submit a job to run in batch.
From what I understand, you want to run 3 programs in by invoking a single command. Is that it?
In OS/400 (haven't used it in over a decade) you put the commands for the programs into a CL source and compile it. Unlike .bat files on Windows, CL isn't going to run without compilation.
Refer to https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_73/rbam6/creat.htm for how to create a CL program.
I have written a program in java that reads .csv files and stores them into a database table. But the performance of the storing operation is very slow. When I use DB2 Command Line Processor there is a drastic change in performance and it's very fast. So, I am trying to customize DB2 Command Line Processor according to my requirement. I searched on Google but I only found topics for how to use it. I would like to get clear on following subjects before I start.
Is "DB2 Command Line Processor" open source?
Which programming language is used?
Is there alternative like DB2 Command Line Processor with open source-code in java?
Is there a way to call DB2 Command Line Processor out of a java program?
It may be worth investigating the Java program, the slow run times may be related to how often you are commiting the data (i.e. you may running in auto-commit mode (commiting after every insert)).
Committing after every 500 insert may be a lot faster than commiting after every record
see DB2 autocommit for details on auto-commit
1) DB2 CLP (command line processor) is part of DB2. It is not open source, and it is included in all editions (Express-C, express, workgroup, extended), and in the Data Server client. This last is free to download, and install in all clients.
2) The best way to use the capabilities os DB2CLP is via scripts, such as bash scripts or windows scripts.
You can also call the db2clp from another program, such as a java application (runtime).
3) There are shells for databases with open source licence, however, you are mixing two things: a shell, that is normally a black screen where you type commands. And a driver to query a database from a program developed by yourself.
4) Again, via Runtime, http://docs.oracle.com/javase/6/docs/api/java/lang/Runtime.html
Finally, the best is to use a JDBC driver, in order to do things directly, and not with a lot of tiers. You have to check your Java code, probably the reading is not efficient. And also, check the properties of the DB2 Java driver.
One more thing, if you want the fatest, try to use LOAD to insert data in the database. It does not perform any log. You can call LOAD from a java application (remember to load the db2 environment before executing any command)
I am deploying project with developer-targeted setup using Inno Setup. I've wrote some code to make some actions that are a bit too custom for the original Inno Setup.
One of such actions was connecting to and running SQL files, thanks to StackOverflow users I've found some code for doing so. The problem is that whenever I try deploying the project on a new Windows Server 2008 machine (x86), I'm getting such cryptic error on every sql command apart from the first one:
"Not enough storage space is available to complete this operation ProgID: ADODB.Connection"
So. The first command fires and works, next stop with error. If I'd run the code again, some of the commands might work, but at some point, the installer would hung. The problem does not exists on windows XP I am writing it on.
I use the code linked above for every SQL command I run (new ole object ADODB.Connection, new command, execute... end) - I don't make the second query for results of insert (as it's there just for showing purpose).
Any thoughts what can be happening here or how can I make a workaround?
