10gr2 libaio.so.1 missing

  1. 10gr2 libaio.so.1 missing

    I've reinstalled it at least 3 times.. each time the file is missing.

    When I startup I get

    oracleWRHS: error while loading shared libraries: libaio.so.1: cannot
    open shared object file: No such file or directory
    ERROR:
    ORA-12547: TNS:lost contact

    I also tried compiling async_on/off with no success

    [WRHS@turin lib]$make -f ins_rdbms.mk async_on
    rm -f /u91/app/oracle/product/10g/rdbms/lib/skgaioi.o
    cp /u91/app/oracle/product/10g/rdbms/lib/skgaio.o
    /u91/app/oracle/product/10g/ rdbms/lib/skgaioi.o
    cp: cannot stat `/u91/app/oracle/product/10g/rdbms/lib/skgaio.o': No
    such file or directory
    make: *** [do_async_on] Error 1

    lastly, I tried linking the file into $ORACLE_HOME/lib directory from
    $ORACLE_HOME/stubs and /usr/lib directories, which is apparently not a
    great thing to do:


    !!! WARNING !!! --> libaio-2.3.2-stub.so

    This is a stub library which can be used for linking only. It must
    *not*
    be used as a runtime library. Please make sure this library is not
    found
    in LD_LIBRARY_PATH.

    On what release are you trying to install this? I don't think 10.2.0
    is certified on 3.0 (assuming you are talking about Linux, you don't
    mention it).

    Regards,

    Ugh.. my bad.

    I have 9.2.0.7 running on it just fine (but no async)

  8. Re: 10gr2 libaio.so.1 missing

    It looks like the async IO libraries were not loaded when Red Hat was
    installed on this server. Try the following:

    rpm -qa *aio*

    If you do not get any libraries loaded, then you'll have to update your
    Red Hat installation. Have your SysAdmin install these libraries.

    Brian,

    They have been loaded.. that's what's confusing. I have followed both
    'official' documentation and http://www.puschitz.com/ and installed all
    the listed RPMs

    [TEST@turin logs]$rpm -qa|grep aio
    libaio-devel-0.3.105-2
    libaio-0.3.105-2


    [root@turin /]# find / -name libaio.so.1
    /u91/app/oracle/product/920/lib/stubs/libaio.so.1
    /u91/app/oracle/product/920/lib32/stubs/libaio.so.1
    /u91/app/oracle/product/102/lib/stubs/libaio.so.1
    /u91/app/oracle/product/102/lib32/stubs/libaio.so.1
    /u91/app/oracle/product/10g/lib/stubs/libaio.so.1
    /u91/app/oracle/product/10g/lib32/stubs/libaio.so.1
    /usr/lib/libaio.so.1

    (102 is std edition, 10g is enterprise edition, both 10gR2)

    OK.. I think I resolved this.. i reinstalled AIO RPMs, I might've had
    non-x64 versions installed as per some earlier instructions. I can't
    believe I spent hours on this today.

    [WRHS@turin create]$ldd $ORACLE_HOME/bin/oracle | grep libaio
    libaio.so.1 => /usr/lib64/libaio.so.1 (0x0000002a96f3b000)


    [root@turin ~]# find / -name libaio.so.1
    /u91/app/oracle/product/920/lib/stubs/libaio.so.1
    /u91/app/oracle/product/920/lib32/stubs/libaio.so.1
    /u91/app/oracle/product/102/lib/stubs/libaio.so.1
    /u91/app/oracle/product/102/lib32/stubs/libaio.so.1
    /u91/app/oracle/product/10g/lib/stubs/libaio.so.1
    /u91/app/oracle/product/10g/lib32/stubs/libaio.so.1
    /usr/lib64/libaio.so.1
