SAP Netweaver 7.10 Disaster Recovery

[Former Member]

Hi all,

I was testing some disaster recovery procedure for one of my SAP systems which has an Oracle 10g backend and is installed on RHEL 5.4 64bit

Practically I backed up and restored all the directories:

/usr/sap/*

/sapmnt/*

/oracle/<SID>/* (only directories containing binaries and log directories)

passwd, shadow, group and gshadow files (so SAP users and groups have the same configs and ids)

home directories of users <sid>adm and ora<mvd>

hostnames also are identical

And after that through the HP DataProtector SAP agent I restored the database and all the archived logs.

I have arranged to start the Database but when trying to restart sap instance the /startsap_DVEBMGS10.log file gives the following:

(3960) Local: rm -f ms.sapMVD_DVEBMGS10

Just to mention that in terms of memory the original machine has 8GB of RAM and 16 logical CPU meanwhile the virtual machine where I am trying to perform the restore has only 2GB and 2 logical CPU

Please help because I am kind of stuck.

Best Regards,

Hello,

Please try...

Perform command to clear any faulty shared memory at OS level:

cleanipc <instance number> remove

i.e cleanipc 00 remove (if the instance number is 00)

Hello,

I had forgotten to replicate the /etc/services file to the new machine.

Now the log files display only failure for the dispatcher process
