Cause

In the Tibero versions with NetBackup integration functionality applied, a dummy library is provided so that the system can boot regardless of whether NetBackup is installed or not.
Note
NetBackup integration feature applied version: patch 155670i or later
 
The dummy library can be found at the following path.
$ ls $TB_HOME/client/lib
libxbsa64.so 
libnbbasecST.so 
libnbclientcST.so
libvxcPBXST.so


If connected to the dummy library as shown below, when performing tbrmgr, SVR Error: -24106 Using netbackup dummy library. Do not use netbackup with dummy library. error message occurs.

$ cd $TB_HOME/bin
$ ldd tbsvr | grep libvxcPBXST.so
libvxcPBXST.so => /tibero_engine/tibero6/client/lib/libvxcPBXST.so (0x00007f5e57434000)

 

Solutions

  • Before installing Tibero, modify the environment variable (LD_LIBRARY_PATH) to set the library path provided by NetBackup (/usr/openv/lib/) to be read first instead of the dummy library, and then proceed with the installation.
  • After installing Tibero, modify the environment variable (LD_LIBRARY_PATH) to set the library path provided by NetBackup (/usr/openv/lib/) to be read first instead of the dummy library, then restart Tibero to enable proper integration.
# Setting LD_LIBRARY_PATH (Prioritize NetBackup path)
$ vi ~/.bash_profile
export LD_LIBRARY_PATH=/usr/openv/lib/:$TB_HOME/lib:$TB_HOME/client/lib

$ tbdown; tbboot

When properly linked to the library provided by NetBackup, it runs as shown below.
$ cd $TB_HOME/bin

$ ldd tbsvr | grep libvxcPBXST.so
libvxcPBXST.so => /usr/openv/lib/libvxcPBXST.so (0x00007fa98144f000)
