CCMS and MAXDB - DlLoadLib error 126

[Former Member]

Dear Gurus,

After configuring DB59 as mentioned in note 588515, I tried to check the connection from ECC to MAXDB and got an error:

B Wed Aug 27 12:21:39 2008
B  create_con (con_name=SDB)
B  Loading DB library 'F:\usr\sap\DEV\DVEBMGS20\exe\dbsdbslib.dll' ...
M  *** ERROR => DlLoadLib: LoadLibrary(F:\usr\sap\DEV\DVEBMGS20\exe\dbsdbslib.dll) Error 126 [dlnt.c       237]
M          Error 126 = "The specified module could not be found."
B  *** ERROR => Couldn't load library 'F:\usr\sap\DEV\DVEBMGS20\exe\dbsdbslib.dll'

B  ***LOG BYG=> could not load library for database connection SDB        [dbds#1 @ 1035] [dbds    1035 ]

It seams that it can't find the dll file but unfortunately the file exists ! so why the error appears ?

Please advice,

Dimitry Haritonov

Hi there,

the

> Error 126 = "The specified module could not be found."

is rather seldom on widows platforms.

What Windows version do you use?

Are the VC++ runtime libs installed?

regards,

Lars

Well - not with managed code

Error 126 is (according to the WinAPI)

"The specified module could not be found. ERROR_MOD_NOT_FOUND"

I've seen a likewise problem on Windows 2008. I think the database client is missing. You have

libSQLDBC.dll

on your system? I think some of the new builds of dbsdbslib.dll have an implicit dependency to the SQL-C runtime...

Hi there -

yep - missing db client - could be the reason... I just assumed that this wouldn't be the problem...

Ah well. I should better watch my assumptions...

If you install e. g. an SCM 5.0 on Oracle the kernel will deliver the dbsdbslib.dll library - but not the MaxDB client (unfortunately).

Hello,

In note 990602 -> section 4 is described that I need to install:

- a MaxDB client installation (Note 649814),

- a current version of the transport program 'tp'.

- the MaxDB-DBSL (Note 325402)

Does it mean I need to install it on the machine of CCMS that will remotely monitor my MAXDB ?

Please advice,

Dimitry Haritonov

In fact you need to have this installed on all application servers that should be able to run DB50/LC10.

The CCMS connects to the MaxDB/liveCache just like any other database client - via the client software. To use this client software, the workprocesses use a standard-adapter, the DBSL.

'TP' is just needed here to provide a access to the "main" database where the logon data are stored.

best regards,

Lars

Are the permissions set correctly? Please check the exact name of the lib.

I've checked the security settings.

Is this problem can be resolved by updating the MaxDB-DBSL ?

Please advice,

[markus_doehr2]

Please check if the library has the correct bitness (32bit vs. 64bit). A 64bit kernel can only load a 64bit dll and vice versa.

Markus

already checked that. my system is x64 and the file is from the AMD KERNEL.

any other ideas ?

[markus_doehr2]

What is the "platform ID" in "System - status" (left bottom)?

Markus

[Former Member]

I didn't understand, please explain what you would like me to check ...

[markus_doehr2]

I'm sorry - your system is not up..

please post the first 15 lines of dev_w0

Ok

So I can't think of a real reason for this problem but

- permission problem (which is apparently not the case)

- bitness (you said you checked and is correct)

- corrupt library

Try to download the latest patchlevel (lib_dbsl) for Windows x64, copy to the directory and start again to start the instance.
