After 720 Kernel Update SAP not starting

[Former Member]

Hi Gurus,

I have done kernel update from 700 to 720 on BI 7.0 (ABAP+JAVA) system and followed note 1636252.

but when i start SAP it is not coming up and when i go and see work/dev* logs observed that SAP is trying to connect with SAPSR3 user but it is not able to connect and giving error as ORA12640 Authentication Adapter initialization failed

before this i have updated on another system with 720 kernel from 701 version but i did not face any error.

please find attachment for error details.

Has any one faced this issue?

Thanks,

Venkat

Hi Venkat,

Can you check the parameter  SQLNET.AUTHENTICATION_SERVICES = (NTS) in your other system where you have successfully upgraded the kernel.

Is it commented over there or active in that system also.

Hi All,

Try to enable tracing (see Troubleshooting Oracle Net Services). After unsuccessful connection post trace file

I would say...

On database server find file {$ORACLE_HOME}\NETWORK\ADMIN\sqlnet.ora  and set it to SQLNET.AUTHENTICATION_SERVICES= (NONE)

Thanks

This may solve the issue but does not answer what root cause of error.

@Venkat,

please check SBP patches installed on both systems.

Hi All,

This issue is resolved by updating oracle patch 10.2.0.5.

Thanks,

Venkat

Can you please make sure you downloaded correct version of DB Dependent files.

Make sure you installed Visual C++ patch if you have MS windows server. (File is in kernel source)

Thanks

Hi Venkat,

What is your OS?

This seems like a problem with SQLNET.AUTHENTICATION_SERVICES parameter in your sqlnet.ora.

Can you post the contents of sqlnet.ora? or compare them with the system that is running?

I can see in the log you are running windows so check that sqlnet.ora has

parameter SQLNET.AUTHENTICATION_SERVICES = (NTS)

Read,

Note 400241 - Problems with ops$ or sapr3 connect to Oracle

Hi Juan,

Thanks for information.

But parameter SQLNET.AUTHENTICATION_SERVICES = (NTS) is there. please have a look on attached screen.

OS: windows 2003 sp2 x64bit, DB: oracle 10.2.0.2

when i revert back old kernel it is working perfectly fine.

why this issue is coming with new 720 kernel?

Thanks,

Venkat

I wonder whats different between the system where the kernel upgrade worked and this one?....  Check Oracle version and patches (By the way 10.2.0.2 needs to be upgraded), oracle client, oracle parameters, etc...

You could also try to recreate the OPS$ Users using oradbusr.sql
