The Instant Client is 64, is a 64 - bit PLSQL;
Companies have more than one database, PLSQL only including a list of database appears click on the left side of the card to death, other data] library can be used normally;
Really don't know what's the problem, because this BUG me to Windows 7 reshipment as the exotic win10, Instant Client and PLSQL from 32-bit to install into 64, and only that a library card dead!!
Have no normal processing work for quite a few days, a great god save ~ ~
