Cause

During the Tibero BOOT process, the libtbcli.dll parses the tbdsn.tbr file. If the format of the tbdsn.tbr file is incorrect, an Access Violation (0xC0000005) exception occurs inside libtbcli.dll, causing the tbsvr.exe process to terminate abnormally.

Solutions

Please delete or correct the incorrectly written parts in the content of tbdsn.tbr and then restart.

Step 1 — Locate the tbdsn.tbr File

%TB_HOME%\client\config\tbdsn.tbr

Step 2 -- Write the tbdsn File in Correct Format

SID name =(
   (INSTANCE=(HOST=localhost)
             (PORT= port_number)
             (DB_NAME= database_name)
   )
)

Step 3 — Check the File Contents

Check the following items in order.

 Step 4 -- Start

$ tbboot
