Problem IT40474
|
Status: Closed |
DB2 ZLIB BACKUP AND LOG FILE COMPRESSION DOES NOT USE HARDWARE ACCELERATION ON UBUNTU
|
| product: |
DB2 FOR LUW / DB2FORLUW / B50 - DB2 |
| Problem description: |
On Ubuntu, the system-provided libz.so.1 is located in a
platform-specific path, which Db2 does not use when searching
for libz.so.1.
Db2 will automatically fall back to the libz support that is
built into the engine, which does not have hardware acceleration
support.
Currently, this only impacts zLinux, which is the only platform
with a hardware-accelerated version of libz.so.1 available. |
