Problem
When running SAP backups, the backint.exe program may not be able to locate and load compatible versions of the needed shared library files.
Error Message
Unable to Locate Component
This application has failed to start because libnbclient.dll was not found, Re-installing the application may fix this problem.
Cause
This is most comonly due to having NetBackup installed in a non-default location on the client host. Once the backint program has been copied to the ...\usr\sap\<SID>\sys\exe\run directory, it will check both the local run directory and the default NetBackup install directory on the C: drive for dependent dll files. But since NetBackup is not installed in the default location, the files will not be located.
This can also occur if there is a failed or incomplete NetBackup installation.
Solution
1) Uninstall the NetBackup client/extension software fron the SAP client host.
2) Delete any residual copies of these files from all the disk drives. This list may vary depending on the version of NetBackup installed.
backint.exe
libVnbat.dll
libnbbase.dll
libnbclient.dll (NetBackup 7.x or higher only)
netbackup.dll
vrtsLogFormatMsg_3.dll
vrtslogread_*.dll
vxACE_*.dll
vxcPBX.dll
vxicudt24l.dll
vxicuin24.dll
vxicuuc24.dll
vxiuuc24.dll
vxlis_*.dll
vxul_*.dll
xbsa.dll
3) Reinstall the NetBackup client software.
4) Perform a manual copy installation of backint per the NetBackup for SAP Administrator's Guide, e.g.
copy "j:\Veritas\NetBackup\bin\backint.exe" "d:\usr\sap\<SID>\sys\exe\run"
5) Review the PATH environment variable that is used by the SAP BR*Tools programs (i.e. brbackup, brarchive,brrestore) to ensure that it includes the ...\NetBackup\bin directory along with any other necessary system and application directories. E.g.
SET PATH=J:\Veritas\NetBackup\bin;C:\Windows\system32 ...
brbackup -t online -m all ...
SAP backup and restore operations should then be successful. If the backint.exe continues to fail to locate and load libraries, contact NetBackup Technical Services to trouble shoot the environment for any potential problem with the linking of library files with the backint.exe program.
