Sequence of Applying Kernel Patches

[Former Member]

Hi All,

We have ECC 5.0 (Central Instance) OS:HP UNIX and four Dialog Instances on Windows Platform.

For Applying the latest kernel patches what should be the sequence, first dialog instances or Central Instance?

For this landscape is it required that while applying kernel patch Database should be in shutdown mode?

Regards,

Prashant.

This is an heterogeneous environment.... so CI and DI's do not share the same kernel directory...

To patch the kernel... you ALWAYS patch first the CI.. so stop the DI's and patch the CI an start it on its own.. once you have check that is fine then patch the DI's and start them.

First we have to apply Support pack in the Dialog instance

The database need not be stopped.

Dear,

>First we have to apply Support pack in the Dialog instance

Its not first dialog instance.

Please follow below steps.

1. shutdown all dialog instances.

2. take backup of current kernel directory

3. stop central instance

4. switch the kernel files from new kernel

5. start the central instance.If its successfully up with new patch level then

6. One by one start the dialog instance.

Note: If the dialog instances sharing the path of Central instance Kernel directory then no need to do anything on dialog instances. Sapcpe program will copy new kernel to dialog instance local kernel directory automatically while restarting the dialog instances.

If dialog instances not sharing the path of CI then repeat the same procedure as of CI for DI's.
