Hello Dheeraj,

Please check note 1836705  - JNI adoption because of security changes in JVM             for this issue.

Hi,

you simply need to install the latest Kernel patch to resolve this issue. The solution is documented in the note

1836705 - JNI adoption because of security changes in JVM

After applying this and restarting the engine, it should come up.

Hi David,

Can we check the kernel patch level at OS level, I have tried jlaunch -v it is showing 721 but not he sp level.

In the note 1836705 - I am confused which one to download as I am unable to find the current patch level.

Thanks,
Dheeraj

Hi Dheeraj,

You can check the current Kernel patch using the following command

sapcontrol -nr <instance number> -function GetVersionInfo

This will display the details required.

David,

I tried replacing the /usr/sap/SID/SYS/exe/run with new kernel I have downloaded.

1. Downloaded latest kernel

2. used SAPCAR to uncar the kernel files(DB & DB independent)

3. stopped the system

4. replaced kernel dir

5. started system

Now DB is not starting

Below is the error from log JdbcCon.log file

Error: Couldn't connect to DB

com.sap.sql.log.OpenSQLException: Exception of type com.ibm.db2.jcc.am.DisconnectNonTransientConnectionException caught: [jcc][t4][2043][11550][4.15.82] Exception java.net.ConnectException: Error opening socket to server us6si1d01/167.105.46.87 on port 5,920 with message: A remote host refused an attempted connect operation.. ERRORCODE=-4499, SQLSTATE=08001.

Please help me

Hi Dheeraj,

Unfortunately, I am not a DB expert. Looks to be an error relating to TCP/IP
