Think Out of the Big Box

A bank customer of us was requesting helps to solve a sudden problem dealing with their IBM DWE server. Apparently from certain date onwards, all the processes executed within the DWE console were failed as shown in the following figure:



Interesting because there are few applications running in DWE and some of them already run for more then 2 years without any problems and now all of them failed at once?

Looking at the logs, obviously db2cmd.exe is throwing out a return code of 5 with exception code SQL1042C which means:



And oh shit, what the hell is the meaning of return code 5?

Tried to google, lookup IBM forums, contacted IBM Support and no one can tell me the definition of code 5?

The real fun is almost all other DB2/DWE components are running fine. db2cc, db2hc, db2start, db2stop, db2licm and many others I tried works. It seems like db2cmd.exe being cursed.

I did many other novel investigations. To name a few:

1. Rule out Windows environment variables
- Open up an instance of command prompt, clear off every environment variable.
- Run db2cmd.exe, still failed with the same error message.

2. Rule out Windows registry
- Open up regedit, throw away \HKEY_LOCAL_MACHINE\SOFTWARE\IBM and one under Current User(Of course, you backup it first)
- Run db2cmd.exe, still failed with the same error message.

3. Rule out corrupted files #1
- Copy db2cmd.exe and all the necessary dll files from my machine into the server.
- Open up command prompt, and point every thing to my new db2cmd.exe folder
- Run db2cmd.exe, still failed with the same error message.

4. Rule out corrupted files #2
- Reinstall DB2 Admin Client (Same FP)
- Run db2cmd.exe, still failed with the same error message.

5. Rule out corrupted files #3
- Reinstall DB2 everything (Latest FP)
- Run db2cmd.exe, still failed with the same error message.

6. Trace through AD GPO/Windows stuffs
- Use gpmc.msc, gpresult, gpedit.msc and many windows tools
- Trace into event viewers
- Look for suspicious items. Nothing found

7. Diagnosing DB2 #1
- Set DB2TEMPDIR to non-existing folder/folder where current user don't have security right to access/write
- db2cmd.exe normally will throw DB2CMD.EXE -> 0, Access denied message.
- Nope, still DB2CMD.EXE -> 5

8. Diagnosing DB2 #2
- Put DIAGLEVEL to 4, restart db2, run db2cmd.exe
- Nothing useful in db2diag.log

9. Diagnosing DB2 #3
- Use db2trc, turn it on, run db2cmd.exe, turn it off.
- Nothing useful.

10. Diagnosing DB2 #4
- Execute db2setcp and db2clpsetcp independently with success.

11. Diagnosing DB2 #5
- Fooling around using db2set, removing settings, changing value to bogus one and adding things.
- Still Error code 5 with db2cmd.exe

12. Finding what the heck is error code 5
- Open db2cmd.exe with notepad, look for any potential hints. Found a list of API used. Cross check API name with return code 5 using Google.
- Seems like return code 5 is usually associated with Access Denied error.

13. Finale
Google again "db2cmd.exe -> 5" +SQL1042C. Found one related post in a china forum. Apparently the fella who faces the problem is a student who was trying out DB2 for some homeworks or so. No solution from the post either.

Very interesting... What is the connection or similarity between a student machine in china and a production level server machine in Malaysia? Indeed, I found the answer to this question and yes, it solved the problem!

Any idea? :D

Weird IBM RPM Catastrophics Error

Our latest IBM RPM customer is opted for a relatively smaller investment in the solution, their system configuration of RPM involved the following components:

DB2 Express-C 9.5
Tomcat 5.5
JDK 5.0
Windows 2003
IBM RPM 7.1.1.2

Based on the instructions of the official guide of IBM RPM 7.1.1.2, there are some additional steps needed for the proper installation of the solution. You can refer to the guide for further information.

The installation took almost 1 day due to our unfamiliarity with such environment because we usually deal with IBM WAS and DB2 ESE. So we did it slowly to avoid unnecessary mistakes.

The installation was a successful one with no error in the logs.

However, a post installation testing procedure revealed some drastic and yet can be frigthening issues, some of them includes:

* When clicked on Investment Map in the Dashboard, it will respond with a EOleException Catastrophics error with some Windows hexadecimal code that translated to a very general error message.

* When try to save text key in the rich text control in the portlet, it will not be saved.

* More EOleException Catastrophic error in other features.

Very interesting indeed because none of the logs (Windows event, tomcat logs and DB2 logs) were unable to reveal any useful hints on the error.

We decided to open a case with IBM Support since the team will be busy doing other functional works.

The communication was established for almost 2 months with no apparent solution to the problem. We did the regular log compilation, scenario description, screen shots blah blah.... At the end, the support even suggested that the DB2 Express-C v9.5 is not supported by the RPM and thus unable to escalate it further. :-S

Since the project is almost near the completion and the risk of this error haunting us is getting more obvious and serious, the team decided to commit more efforts to fix it.

Here are the problem solving sequences we took:

Note: Our VM Test environment doesn't have the EOleException problem. Thus we believe it is environment specific, not a product bug.


1. Disable all irrelevant services in the OS and test
- Unchanged. Rule out the problem of software conflicting
- Enable back everything

2. Run the RPM Client outside the server machine, i.e. client workstation
- Unchanged. Confirmed it is server based problem. RPM Standalone and Plugins behaves the same.

3. Accidentally we had tried this scenario and found out something interesting.
We opened up the RPM Client and triggered the EOleException catastrophics error and then clicked Ok to continue. Then we recycled the Tomcat while the client was opened. The error will not triggered again and everything is fine, including the rich text control saving problem.
- This has revealed an important hint that the problem is caused by something shared between the client program and the Tomcat in the server.
- Since the client program is a Windows executable, possibly this got to do with some DLLs or something that the client program "loaded" before the Tomcat. I can't be sure since I don't have access to the source codes.

4. We checked the java.library.path from the Tomcat logs and found that there are another copy of xercesImpl.jar and xmlApi.jar in the path. To play safe, we removed these files and tested again. No luck.
- Rules out the problem of JAR class loading because logically the client program and Tomcat doesn't really use them together (I think).

5. A tip that we learnt from the Support is that we can stream out the logs generated by the client program using the "RPMStdIn.exe > logs.txt" and this log will contain information such as stored procedure called with parameters.
- By triggering the error, now the logs.txt contains the stored procedure that causes the error.

6. From 5 above, we copied the call information and executed it directly in DB2
- No errors returned from DB2. This confirmed the problem with how Tomcat or something inside Tomcat interpret or handle the SP call.

7. Confirm the JDBC Driver
- No problem as we directly used the drivers from the local DB2 Express-C.

8. Ruling out so many things and we start to suspect something more fundamental causes this, i.e. the Java execution environment. A check on the Tomcat JRE indicated the use of JRE 1.5.0.2. Cross referenced to Tomcat 5.5 and RPM 7.1.1.2 and none of the manual said anything about a particular level of J2SE 5.0 to be used.
- Since we running out of options, we decided to upgrade the JRE to 1.5.0.16 since that version was used in our VM too (LOL, we realized that too late I guess)
- Bingo, the error is no more.
- To reconfirm, we installed JRE1.5.0.2 in our VM and let the Tomcat used it and we managed to resimulate the problem, which is something that we were unable to perform since the reporting of the case to the Support.


All this havoc just because of insufficient information from the official about supported environments for RPM. Aiks.

P/S: IBM RPM guide never mentioned about the DB2 editions supported and this might be a grey area on the supportability of any RPM deployments.

Professionally, I strongly believe that CA Clarity did a great job on explicitly documented down the supported environments to the details on levels, fix packs, versions and so on. It can help to get rid of weird problem(s) like the one we encountered here.

UDF and SP in IBM RPM

IBM Rational Portfolio Manager (assuming version 7.1.1.2) is using Dynamic Linking Library (DLL) as its implementation for some of the database objects, namely stored procedure (SP) and user defined functions (UDF). More precisely the file name of this dll is IBMRPM.dll and it resides in two locations, i.e. ${DB2_INSTALL_ROOT}\FUNCTION\IBMRPM.dll and ${DB2_INSTALL_ROOT}\FUNCTION\unfenced\IBMRPM.dll.

During RPM installations/migrations, the process will define the linkage between SP/UDF to the appropriate methods in the dll and this piece of information is stored in SYSIBM.SYSROUTINES table's IMPLEMENTATION column.

The problem with IBM RPM installation is that it hardcoded the directory information in IMPLEMENTATION column. This shall causes portability issue when you desire to move the system to another environment where the ${DB2_INSTALL_ROOT} is not consistent with each other. For example, your initial RPM machine might have DB2 at drive C then the latest environment put it in drive E.

In such a setting, after you restored the database successfully into the new environment, you shall get alerts and some errors in the application server's logs specifying database errors with SQLSTATE 42724 REASON CODE 4.

You maybe be tempted to update the path information directly in SYSIBM but the column is only updateable through a proper DROP/CREATE PROCEDURE or ALTER PROCEDURE and in this case the number of objects to change is way too many even if you plan to write a batch script for it.

A shortcut to this problem is to copy the IBMRPM.dll and create the necessary dummy folders that reflect the original path information and paste them there. This works but it's not recommended because it might causes complication next time when doing patching or upgrading of RPM.

The best way to resolve this is to reuse some of the scripts from the installer.

Note: Please do this at your own risk. Backup everything first.


Step 1: Setting Up Environment

To do this, open up an instance of DB2CMD.

Change Directory (CD) to ${RPM_INSTALLER}\Database\DB2\Windows\CSP

If you are using DB2 V9, Please set the following environment variables using:

SET DB2TEMPDIR=${DB2_INSTALL_ROOT}\

Note: Please make sure the above path end with a slash (\)

Then

SET RPMDLLNAME=IBMRPM

You will then login to DB2 by using the user name where the name is the schema name of the objects. For example, DB2ADMIN. If you are not sure what name is that, you can always open up the control center and browse the list of stored procedures and check the schema name column. A common procedure is the SP_LOGON.

db2 connect to MYRPM user db2admin using your_password

Step 2: Recreate SP/UDF

Run the drop_sp.bat by using the following command:

drop_sp.bat > drop_sp.log

Check the drop_sp.log to verify the completion.

Run the create_sp.bat by using the following command:

create_sp.bat > create_sp.log

Check the create_sp.log to verify the completion.

Step 3: Bind packages

Because the dropping of previous SP/UDF invalidated package objects used by RPM, you need to bind them again. Open bindall.bat using notepad or other editor. Copy the for loop command and paste it in a new file. Name the file bindall2.bat. Change the value for QUALIFIER to DB2ADMIN. Save it and run the following command using the previous DB2 Command Window session.

bindall2.bat > bindall2.log

Check the bindall2.log to verify the completion.

You might to recycle your DB2 process to get a fresh start.

db2diag.log hexadecimal error number to DB2 SQLCODE

The error number conversion table below is intended for the hex error # in db2diag.log to db2 sqlcode. For example, the hex error number ending with 80D3 can be looked up by db2 ? command using SQL4977N sqlcode. -4977 is equivalent to 4977N (N for negative).
