vertical bar is not 0?
With these questions, let's look at the following example:
Console. log (3 | 4); // 7Console. log (4 | 4); // 4Console. log (8 | 3); // 11Console. log (5.3 | 4.1); // 5Console. log (9 | 3455); // 3455
Here we mention the single vertical bar "|" but there is no javascript.
Okay, let me publish the answer here. In fact, a single vertical bar "|" is the result obtained after being converted to a binary hexadecimal notation. For example, let's take a simple example:

Other SGA components are placed in the regular memory, instead of in this shared memory file system, do not include shmfs in the shmfs, which is slightly larger than the actual size, in this example, I use 3G shmfs as the cache.
