Known Limitations

Table 1 describes the known limitations for Oracle Tuxedo and provides recommended workarounds.

 

Table 1 Known Limitations

1.	[TLISTEN] Slave node cannot be started. CMDTUX_CAT:4291 error message
	Description	Using Tuxedo 11gR1 as master in MP mode, if you installed a previous Tuxedo version and did not change tlisten password after installation, you will receive a security negotiation error message (CMDTUX_CAT:4291).
	Platforms	All
	Workaround	In the previous Tuxedo version, you must add one blank line to $TUXDIR/udataobj/tlisten.pw tail.

 

Product Constraints

Table 2 describes product constraints for Oracle Tuxedo and provides recommended workarounds.

 

Table 2 Product Constraints 

1.	BBL may fail to boot on AIX platform if MAXSERVICES value defined in UBBCONFIG is more than approximate 700000
	Description	• Tuxedo system binaries were compiled on AIX platform without using the Large Address-Space Model. Thus Tuxedo system servers can only access up to 256MB (only 1 segment) for heap and stack size altogether by default due to AIX process model constraints. If MAXSERVICES defined is very large and the needed heap size exceeds 256MB, BBL will result a malloc() failure and fail to boot. • Upper limit of the MAXSERVICES value on AIX platform by default is approximate 700000.
	Platforms	IBM AIX
	Workaround	Starting from AIX 5, environment variable LDR_CNTRL is introduced to control the number of memory segment that a process can use for data. 2 segments are enough to support the maximum MAXSERVICES value 1,048,575. It's recommended to set environment variable LDR_CNTRL only for booting Tuxedo, other Tuxedo command utilities with LDR_CNTRL setting may not work properly. Do the following sample steps: 1. ulimit -d unlimited 2. export LDR_CNTRL=MAXDATA=0x20000000 3. tmboot 4. unset LDR_CRTRL
