OracleFaq (Oracle version)

If you need to reprint it, please indicate the source. Thank you! Take 8.1.7.4.0 as an example: 8: Version 1: new feature version 7: maintenance version 4: normal patch setting number 0: the special platform patch setup number is also related to Oracle 32bit/64bit, which is described as follows: in windows/linux systems, oracle must be 32bit because the operating system is 32bit; in tru64, oracle must be 64bit. In hpux/aix/solaris, it depends on the specific situation. If 64bit is used to start sqlplus on the server, 64bit is displayed, you can also view it through select * from v $ version; or $ file $ ORACLE_HOME/bin/oracle | more, for example: $ File $ ORACLE_HOME/bin/oracle | more/data1/app/oracle/product/8.1.7/bin/oracle: ELF-64 executable object file-PA-RISC 2.0 (LP64) if you want to support SGA larger than 1.75GB, we recommend that you use 64-bit oracle. 32bit Oracle has limits on the size of SGA. Although many platforms have a way to bypass the past, it is easier to use 64 bit directly after all, and even if the past, it cannot be opened. Nothing else.
