sybase 数据load数据出问题，请高手帮助！

ackup Server session id is:  5.  Use this value when executing the
'sp_volchanged' system stored procedure after fulfilling any volume change
request from the Backup Server.
Backup Server: 4.124.2.1: Archive API error for
device='comepress::6::/opt/sybase-12.5/backup/20101130/ksqhdb_20101130_part4.c6dmp::03': Vendor application name=<UNINIT>, Library version=0, API routine=<UNINIT>, Message=Unable to open API library for device 'comepress::6::/opt/sybase-12.5/backup/20101130/ksqhdb_20101130_part4.c6dmp'. Library path is '/opt/sybase-12.5/ASE-12_5/lib/libcomepress.so'. dlopen() returned: Code=0, Message=/opt/sybase-12.5/ASE-12_5/lib/libcomepress.so: cannot open shared object file: No

/opt/sybase-12.5/ASE-12_5/lib/libcomepress.so
是否存在？

在isql下检查backup服务是否正常？

SYB_BACKUP...sp_ps

BACKUP是起来的，不久前，还能正常load，不知道怎么搞的，现在总是出这个错，即使我不使用comepress,也无法load！

我在现在等待各位兄弟的帮助，谢谢！
